The Degree of Inferior Vena Cava Filter Tilt Associated with Challenging Retrieval.

BACKGROUND: Inferior vena cava (IVC) filter tilt is associated with technical difficulties at the time of retrieval. However, the degree of tilt that predisposes patients to undergo complex or failed retrieval has not been defined. METHODS: The electronic charts of patients undergoing IVC filter removal between 2010 and 2019 at a single tertiary center were reviewed. Patient and procedural characteristics were recorded. Venograms of placement and retrieval procedures were reviewed, and IVC filter tilt was determined based on its deviation from the IVC axis. IVC diameter and the distance from the lowest renal vein were measured using corresponding filter's length for calibration. All measurements were performed by 3 reviewers and confirmed by 2 reviewers. Patients were divided into 2 groups: those who underwent successful removal procedures requiring standard retrieval methods ("simple retrieval group") and those who required advanced endovascular techniques or had failed completely IVC filter retrievals ("challenging retrieval group"). A regression analysis was performed to determine factors associated with challenging retrieval. RESULTS: There were 365 patients who underwent IVC filter retrieval (n = 294 (80.6%) and n = 71 (19.4%) in the simple and challenging groups, respectively) with no difference in age, sex, comorbidities, or indication between the 2 groups. Failed retrieval occurred in 21 patients (5.8%) and was more common among patients requiring advanced endovascular techniques compared to standard techniques (18.0% vs. 3.2%, P < 0.001). In the overall cohort, the mean filter tilt at the time of retrieval was 4.9° ± 4.4° [0c27°], and 145 patients (39.7%) had a filter tilt ≥5.0°. Compared to the simple retrieval group, patients in the challenging group had significantly longer dwell time, greater tilt of IVC filter during placement and retrieval, as well as higher tilt change between the 2 venograms. There was no correlation between the access site during placement and challenging retrieval. However, patients undergoing filter placement via right jugular vein had lower filter tilt as compared to femoral access. Patients with filter tilt ≥5.0° were more likely to have a challenging filter retrieval compared to patients with ˂5.0° tilt (29.7% vs. 12.7%, P < 0.001). Regression analysis showed that tilt ≥5.0° (odds ratio [OR] = 1.18 [1.11-1.25]), dwell time (OR = 1.04 [1.01-1.07]), and age (OR = 0.97 [0.95-0.99]) were independently associated with challenging retrieval. CONCLUSIONS: IVC filter tilt ≥5.0°, dwell time and age are associated with challenging retrieval. Right jugular vein access, multiple imaging projections, and careful filter manipulation during deployment should be considered to maintain tilt at ˂ 5.0° and decrease the likelihood of challenging retrieval.

Intravascular Ultrasound Use is Associated with Improved Patency in Lower Extremity Peripheral Arterial Interventions.

BACKGROUND: Intravascular ultrasound (IVUS) facilitates detailed visualization of endoluminal anatomy not adequately appreciated on conventional angiography. However, it is unclear if IVUS use improves clinical outcomes of peripheral vascular interventions (PVIs) for peripheral arterial disease. This study aimed to evaluate the impact of IVUS on 1-year outcomes of PVI in the vascular quality initiative (VQI). METHODS: The VQI-PVI modules were reviewed (2016-2020). All patients with available 1-year follow-up after lower extremity PVI were included and grouped as IVUS-PVI or non-IVUS PVI based on use of IVUS. Propensity matching (1:1) was performed using demographics and comorbidities. One-year major amputation and patency rates were compared. A generalized estimating equation model was used to identify predictors of 1-year outcomes. Subgroup analysis based on Trans-Atlantic Intersociety Consensus (TASC) classification, treatment length and treatment modalities were performed using same modeling approaches. RESULTS: There were 56,633 procedures (non-IVUS PVI = 55,302 vs. IVUS-PVI = 1,331) in 44,042 patients. Propensity matching yielded a total cohort of 1,854 patients matched (1:1), with no baseline differences. Lower extremity revascularization for claudication was performed in 60.4%, while one-third (33.9%) had chronic limb threatening ischemia (CLTI). IVUS was more commonly used for lesions >15 cm in length (46.6% vs. 43.3%) and for aortoiliac disease (31.8% vs. 27.2%). Rates of atherectomy and stenting were significantly higher with IVUS-PVI (21.1% vs. 16.8%), while balloon angioplasty was less common (13.5% vs. 24.4%). One-year patency was better with IVUS-PVI (97.7% vs. 95.2%, P = 0.004). On subgroup analysis, IVUS (odds ratio [OR] 2.20, 95% confidence interval [CI] 1.29-3.75) was associated with improved patency in CLTI patients, TASC C or D lesions, and treatment length >15 cm. Adjunctive IVUS use during PVI did not significantly impact 1-year amputation (OR 1.7, 95% CI 0.78-3.91). On multivariable regression, adjunctive use of IVUS (OR 2.46 95% CI 1.43-4.25) and aortoiliac interventions (OR 2.91, 95% CI 1.09-7.75) were independent predictors of patency. Treatment modalities such as atherectomy, stenting or balloon angioplasty did not significantly impact patency at 1-year. CONCLUSIONS: IVUS during lower extremity PVI is associated with improved 1-year patency, when compared to angiography alone. Certain subgroups, such as CLTI patients, lesions>15 cm, and TASC C or D lesions might benefit from adjunctive use of IVUS.

Comparative analysis of negative pressure wound therapy (PICO) and standard dressing application after arterial vascular reconstructions.

INTRODUCTION: Surgical site infections following arterial reconstructions with femoral exposures are common and potentially preventable. Negative pressure wound therapy has emerged as a potential solution to minimize groin wound complications. Our study evaluates efficacy of a negative pressure therapy (PICO dressing) in reducing groin wound complications after vascular reconstructions. METHODS: A retrospective single center comparative analysis of vascular reconstructions involving common femoral artery dissection was performed between July 2021 and June 2023. Patients were divided into two groups: patients treated with PICO device and patients who received standard dressing (non-PICO). Patient demographics, comorbidities, vascular evaluation, and procedure indications were compared. Previous interventions, incision orientation and procedure types were noted. The wound complication categories were graded according to the Szilagyi classification: grade 1 (superficial infection/minor dehiscence), grade 2 (deep infection/major dehiscence), and grade 3 (artery or prosthetic involvement). Statistical significance level was determined at p < .05 for all analyses. RESULTS: A total of 217 groin dissections in 184 patients were analyzed with 132 and 85 groin dissections in the PICO and non-PICO groups, respectively. The baseline characteristics were similar between the groups in terms of age, sex, BMI, and procedure indications. Prior endovascular procedures and re-operative groin surgeries were more prevalent in the PICO group. The use of antibiotics post-operatively for groin wound complication was greater in the non-PICO group. The incidence of wound complications was higher in the non-PICO group (29.4% vs 10.6%, p < .001). Multivariate logistic regression analysis determined that PICO dressing as well as hybrid and endovascular index procedures were associated with lower risks of groin complications. CONCLUSION: PICO dressing decreased the incidence of groin wound complications in patients undergoing open vascular reconstructions. This study highlights the value of adjunctive negative pressure therapy in reduction of wound complications after arterial reconstructions in the inguinal region.

Automatic measurement of short-term variability of repolarization to indicate ventricular arrhythmias in a porcine model of cardiac ischaemia.

AIMS: An automated method for determination of short-term variability (STV) of repolarization on intracardiac electrograms (STV-ARIauto) has previously been developed for arrhythmic risk monitoring by cardiac implantable devices, and has proved effective in predicting ventricular arrhythmias (VA) and guiding preventive high-rate pacing (HRP) in a canine model. Current study aimed to assess (i) STV-ARIauto in relation to VA occurrence and secondarily (ii-a) to confirm the predictive capacity of STV from the QT interval and (ii-b) explore the effect of HRP on arrhythmic outcomes in a porcine model of acute myocardial infarction (MI). METHODS AND RESULTS: Myocardial infarction was induced in 15 pigs. In 7/15 pigs, STV-QT was assessed at baseline, occlusion, 1 min before VA, and just before VA. Eight of the 15 pigs were additionally monitored with an electrogram catheter in the right ventricle, underwent echocardiography at baseline and reperfusion, and were randomized to paced or control group. Paced group received atrial pacing at 20 beats per min faster than sinus rhythm 1 min after occlusion. Short-term variability increased prior to VA in both STV modalities. The percentage change in STV from baseline to successive timepoints correlated well between STV-QT and STV-ARIauto. High-rate pacing did not improve arrhythmic outcomes and was accompanied by a stronger decrease in ejection fraction. CONCLUSION: STV-ARIauto values increase before VA onset, alike STV-QT in a porcine model of MI, indicating imminent arrhythmias. This highlights the potential of automatic monitoring of arrhythmic risk by cardiac devices through STV-ARIauto and subsequently initiates preventive strategies. Continuous HRP during onset of acute MI did not improve arrhythmic outcomes.

Sex differences in long-term outcomes of patients with deep vein thrombosis.

OBJECTIVE: Sex differences in short-term outcomes of patients with deep vein thrombosis (DVT) have been reported, but differences in long-term outcomes remain poorly characterized. This study aimed to evaluate sex differences in long-term mortality, venous thromboembolism (VTE)-related mortality, and bleeding-related mortality in patients with DVT at a tertiary care center. METHODS: A retrospective chart review from 2012 to 2018 of all consecutive patients diagnosed with DVT was performed. Patients were grouped by sex, and baseline characteristics and treatment modalities were compared. Long-term outcomes of recurrent VTE, bleeding, and related mortalities were analyzed. Multivariable regression analysis was performed to determine factors associated with overall mortality. RESULTS: A total of 1043 (female = 521 and male = 522) patients with DVT were captured in this study period. Female patients were older (64.7 vs 61.6 years old, p = 0.01) and less likely to be obese (68.2% vs. 71.1%, p = 0.04),but had a higher average Caprini score (6.73 vs 6.35, p = 0.04). There was no difference in anatomic extent of DVT, association with PE, and severity of PE between sexes. Most patients (80.5%) were treated with anticoagulation, with no differences in choice of anticoagulant or duration of anticoagulation between females and males. Male patients were more likely to undergo catheter-directed thrombolysis (CDT) for DVT (4.2% vs 1.7%, p = 0.02) and PE (2.7% vs 0.9%, p = 0.04). Female patients were more likely to receive systemic thrombolysis for PE (2.9% vs 1.1%, p = 0.05). After an average 2.3 years follow-up, there was significantly higher bleeding complications among females (22.2% vs 16.7%, p = 0.027). The overall mortality rate was 33.5% and not different between males and females. Females were more likely to experience VTE-related mortality compared to males (3.3% vs 0.6%, p = 0.002). On regression analysis, older age (OR = 1.04 [1.03-1.06]), cancer (OR = 7.64 [5.45-10.7]), and congestive heart failure (OR = 3.84 [2.15-6.86]) were independently associated with overall mortality. CONCLUSIONS: In this study, there was no difference in overall long-term mortality between sexes for patients presenting with DVT. However, females had increased risk of long-term bleeding and VTE-related mortality compared to males.

Trends in Utilization and Outcomes of Orbital, Laser, and Excisional Atherectomy for Lower Extremity Revascularization.

PURPOSE: The aim of this study is to analyze the utilization pattern of atherectomy modalities and compare their outcomes. MATERIALS AND METHODS: All patients undergoing atherectomy in the 2010-2016 Vascular Quality Initiative Database were identified. Utilization of orbital, laser, or excisional atherectomy was obtained. Characteristics and outcomes of patients treated for isolated femoropopliteal and isolated tibial disease by different modalities were compared. RESULTS: Atherectomy use increased from 10.3% to 18.3% of all peripheral interventions (n = 122 938). Orbital atherectomy was most commonly used and increased from 59.4% in 2010 to 63.2% of all atherectomies in 2016, while laser atherectomy decreased from 19.2% to 13.1%. Atherectomy was mostly used for treatment of isolated femoropopliteal disease (51.1%), followed by combined femoropopliteal and tibial disease (25.8%) and isolated tibial disease (11.7%). In isolated femoropopliteal revascularization, excisional atherectomy was associated with higher rate of perforation (1.2%) compared with laser (0.4%) and orbital atherectomy (0.5%). The technical success of orbital atherectomy (96.7%) was lower compared with excisional atherectomy (98.7%). Concomitant stenting was significantly higher with laser atherectomy (43.0%) compared with orbital (27.2%) and excisional (26.1%) atherectomy. Nevertheless, there was no difference in 1-year primary patency, reintervention, major amputation, improvement in ambulatory status, or mortality. Multivariable analysis also demonstrated no difference in 1-year primary patency and major ipsilateral amputation among the modalities. In isolated tibial revascularization, there were no differences in perioperative outcomes among the modalities. Excisional atherectomy was associated with the highest 1-year primary patency (88.1%). After adjusting for confounders, excisional atherectomy remained associated with superior 1-year primary patency compared with orbital atherectomy (odds ratio [OR] = 2.59, 95% confidence interval [CI] = [1.18-5.68]), and excisional atherectomy remained associated with a lower rate of 1-year major ipsilateral amputation compared with laser atherectomy (OR = 0.29, 95% CI = [0.09-0.95]). CONCLUSION: Atherectomy use has increased, driven primarily by orbital atherectomy. Despite significant variation in perioperative outcomes, there were no differences in 1-year outcomes among the different modalities when used for treating isolated femoropopliteal disease. In isolated tibial disease treatment, excisional atherectomy was associated with higher 1-year primary patency compared with orbital atherectomy and decreased major ipsilateral amputation rates compared with laser atherectomy. These differences warrant further investigation into the comparative effectiveness of atherectomy modalities in various vascular beds.

Alternative Endograft Aortoiliac Reconstruction for Iliac Branch Endoprostheses.

BACKGROUND: Endovascular treatment of complex common iliac artery (CIA) and internal iliac artery (IIA) aneurysms using iliac branch endoprostheses (IBE) has proven safe and effective. Instructions for use (IFU) require deployment of current IBE technology with the corresponding manufacturer's modular bifurcated aortic endograft. Concomitant aortoiliac occlusive disease, inadequate renal artery-iliac bifurcation length, and unfavorable aortic anatomy preclude on-label IBE deployment. This study aimed to evaluate the technical feasibility and safety of Alternative Endograft Aortoiliac Reconstruction (AEGAR) for branched endovascular treatment of complex iliac artery aneurysms. METHODS: In 7 consecutive patients with CIA or IIA aneurysms, computed tomography angiography (CTA) and center-line reconstruction revealed aortoiliac anatomy incompatible with the current IBE IFU due to inadequate proximal CIA landing zone (n = 7), inadequate renal artery to iliac bifurcation length (n = 2), compromised aortic anatomy (n = 3), or short infrarenal neck <15 mm (n = 1), either alone or in combination. To overcome these restrictions and facilitate IBE deployment, aortoiliac reconstruction was performed using the Endologix AFX, Endologix Ovation limbs or the Medtronic Endurant II platforms (AEGAR technique). All internal iliac artery reconstructions and external iliac artery extensions were performed using the Gore VBX or Viabahn stent grafts. Technical success was defined as successful delivery of all endograft components without migration or endoleak. RESULTS: The mean patient age was 69 years (range 52-82 years; 6 male). Four patients had bilateral CIA aneurysms and 3 patients had unilateral CIA aneurysms (mean diameter 4.3cm; range 2.2-7 cm). There were 13 IIA VBX stent grafts used for a total of 9 IIAs treated with IBE (bilateral IBE = 2 patients). The mean fluoroscopy time was 38.8 min (range 21.3-64.3 min) and the mean contrast volume was 168.5 mL (range 122-226 mL). Technical success was achieved in all patients and there were no perioperative complications. Mean hospital-stay was 2.2 days (range 1-3 days). Follow-up ranged from 82-957 days (mean = 487 days). At last follow-up, all patients were alive without cardiovascular morbidity; and CTA revealed stable or decreased aneurysm size, patent endografts, and no evidence of endoleak or migration. CONCLUSIONS: The AEGAR technique can be used to safely and effectively overcome certain aortoiliac anatomic constraints that preclude use of current IBE technology. We encourage broader use of these alternative endografts in pertinent anatomic configurations.

Masticatory performance and oral health-related quality of life in edentulous maxillectomy patients: A cross-sectional study to compare implant-supported obturators and conventional obturators.

OBJECTIVE: The aim of this cross-sectional study was to compare the masticatory performance and oral health-related quality of life (OHRQoL) of edentulous maxillectomy patients with and without implant-supported obturator prostheses. MATERIAL AND METHODS: Nineteen edentulous maxillectomy patients with completed prosthetic obturator treatment in the upper jaw participated in this study. In nine patients, the obturator prosthesis was supported by implants in the remaining bone of the midface and/or skull base to improve retention. Masticatory performance was measured objectively by the mixing ability test (MAT) and subjectively by three OHRQoL questionnaires: (a) the Oral Health Impact Profile for EDENTulous people (OHIP-EDENT), (b) the Obturator Function Scale (OFS), and (c) the Dutch Liverpool Oral Rehabilitation Questionnaire version 3 (LORQv3-NL). The independent t test and the Mann-Whitney U test were used to test for differences in outcomes of patients with and without implant-retention of their obturator prostheses. RESULTS: Patients with implant-supported obturator prostheses had significantly better masticatory and oral function, reported fewer chewing difficulties, and had less discomfort during food intake than did patients with a conventional obturator. CONCLUSION: Supporting prosthetic obturators after maxillectomy with implants improve oral functioning, chewing, and eating comfort. This treatment modality is a viable technique to improve the functionality of prosthetic rehabilitation in patients who have undergone maxillectomy.

Comparison of Atherectomy to Balloon Angioplasty and Stenting for Isolated Femoropopliteal Revascularization.

BACKGROUND: The use of atherectomy for lower extremity revascularization is increasing despite concerning reports about its long-term safety and effectiveness. This study compares the outcomes of atherectomy to percutaneous transluminal angioplasty (PTA) and stenting for treatment of isolated femoropopliteal disease. METHODS: All patients undergoing endovascular treatment of isolated femoropopliteal lesions in the Vascular Quality Initiative (2009-2018) were identified. Patients with concomitant open surgery, acute limb ischemia, or iliac or tibial intervention were excluded. Patients were divided into 3 treatment groups: atherectomy with or without PTA, PTA alone, and stenting alone. Propensity matching was performed based on age, gender, race, ambulatory status, diabetes, smoking, hypertension, coronary artery disease, chronic obstructive pulmonary disease, congestive heart failure, dialysis, prior inflow bypass and intervention, prior major ipsilateral amputation, indication, length of treated lesion, American Society of Anesthesiologists class, and Trans-Atlantic Society Consensus II classification. The perioperative and one-year outcomes of the matched groups were compared. RESULTS: A total of 10,007 cases of atherectomy, 22,000 cases of PTA, and 27,579 cases of stenting of isolated femoropopliteal disease were identified. After matching, there were 6,372 procedures in atherectomy and PTA groups, respectively. Atherectomy was associated with higher likelihood of technical success (98.3% vs. 97.5%; P < 0.001) and shorter length of stay (1.8 ± 8.2 days vs. 2.7 ± 15.7 days; P < 0.001), but had increased rate of distal embolization (2% vs. 1.1%; P < 0.001) compared with PTA. At one year, atherectomy was associated with improved primary patency (84.2% vs. 82%; P = 0.047) and survival rate (91.1% vs. 90%; P = 0.044), but was also associated with a higher reintervention rate (15.7% vs 13.6%; P = 0.033) compared with PTA. There was no difference in the rates of major amputation, ambulatory status improvement, or ankle brachial index (ABI) improvement. In the second analysis, after matching, there were 6,877 procedures in the atherectomy and stenting groups, respectively. Atherectomy was associated with lower rate of dissection (3.7% vs. 8.2% <0 .001), lower rate of perforation (0.6% vs. 1.2%; P < 0.001), and a shorter length of stay (1.9 ± 8.1 vs. 2.9 ± 9.8 days; P < 0.001) than stenting. However, patients treated with atherectomy had a lower rate of technical success (98.3% vs. 99.2%; P < 0.001) and a higher rate of distal embolization (2% vs. 1.2%; P < 0.001) than stenting. At one year, atherectomy was associated with a higher rate of major ipsilateral amputation (5.3% vs. 4.1%; P = 0.046) and less improvement in ABI (0.19 ± 0.42 vs. 0.25 ± 0.4; P < 0.001) than stenting. There was no difference in rates of primary patency, survival, reintervention, and ambulatory status improvement at one year. CONCLUSIONS: Atherectomy does not seem to confer any significant additional clinical benefit compared with balloon angioplasty or stenting. Further research is needed to justify its additional cost over other endovascular modalities.

Management of foot/ankle osteoarthritis by Australian general practitioners: an analysis of national patient-encounter records.

OBJECTIVE: To document the management of foot/ankle osteoarthritis/arthritis (OA) by general practitioners (GP) in Australia. DESIGN: We analysed data from the Bettering the Evaluation and Care of Health Program April 2010-March 2016 inclusive. Patient and GP encounter characteristics were extracted. Data were classified by the International Classification of Primary Care, Version 2, and summarised using descriptive statistics and 95% confidence intervals (95% CIs) around point estimates. RESULTS: The dataset included 583,900 patient-encounter records among which foot/ankle OA was managed 621 times, at a rate of 1.1 per 1000 encounters, with an annual estimated 152,000 GP encounters nationally. The management rate was most frequent among patients aged 65-74 years (2.25 per 1000 encounters). Comorbidities were managed at a rate of 105.8 per 100 encounters, the most common being hypertension, and few being other musculoskeletal problems. Foot/ankle OA was mostly managed using medication (64.6 per 100 problems), with prescription rates far exceeding non-pharmacological strategies such as counselling, advice or education (17.7 per 100), or allied health referral (10.1 per 100). When considering specific health/medical professionals, patients were referred to orthopaedic surgeons 8.4 times per 100 foot/ankle problems, podiatrists 6.3 times per 100 foot/ankle problems, and physiotherapists 2.6 times per 100 foot/ankle problems. CONCLUSIONS: Pharmacological management rates of foot/ankle OA were high and substantially exceeded non-pharmacological management such as lifestyle advice and allied health referral. Longitudinal studies are needed to determine the effectiveness of this care compared to self-management and conservative non-drug treatment in people with foot/ankle OA.

Better survival for African and Hispanic/Latino Americans after infrainguinal revascularization in the Society for Vascular Surgery Vascular Quality Initiative.

OBJECTIVE: Inferior survival outcomes have historically been reported for African Americans with cardiovascular disease, and poorer outcomes have been presumed for peripheral arterial disease (PAD) as well. The current study evaluates the effect of race and ethnicity on survival of patients undergoing open or endovascular interventions for lower extremity PAD. METHODS: Data of patients from the Society for Vascular Surgery Vascular Quality Initiative database were obtained for patients undergoing open infrainguinal (INFRA) or suprainguinal (SUPRA) bypass, peripheral vascular intervention (PVI), and amputation (AMP). Patients were further stratified as suprainguinal (SupraPVI) if any of the first three interventions listed included the aorta or iliac vessels or infrainguinal (InfraPVI) if not. The primary outcome was the patient's death (overall mortality) as recorded in the database or determined by cross-reference with the Social Security Death Index (SSDI). The secondary outcome consisted of perioperative mortality during the index hospitalization. Generalized linear modeling provided multivariate analysis, with entry of variables dependent on results of univariate analysis. RESULTS: From January 2003 through September 2015, a total of 24,241 INFRA bypass, 8028 SUPRA bypass, 48,048 InfraPVI, 21,196 SupraPVI, and 3423 AMP patients met criteria for analysis, with a median follow-up of 18 (interquartile range, 8-33) months. Combining all procedures, overall mortality was lower among African Americans than among white Americans (12.4% vs 14.2%; P < .0001) but not death in the periprocedural period (1.1% vs 1.2%; P = .26). To account for differences in length of follow-up, Cox proportional hazards analysis confirmed that the African American race was independently associated with a significantly lower occurrence of overall mortality after INFRA bypass (hazard ratio [HR], 0.78; 95% confidence interval [CI], 0.70-0.88; P < .0009), InfraPVI (HR, 0.72; 95% CI, 0.67-0.78; P < .0001), and SupraPVI (HR, 0.77; 95% CI, 0.66-0.90; P = .0009) interventions but not after SUPRA bypass or AMP. Similarly, by Cox proportional hazards, Hispanic/Latino ethnicity was also independently associated with lower overall mortality after INFRA bypass (HR, 0.75; 95% CI, 0.62-0.91; P = .0030), InfraPVI (HR, 0.69; 95% CI, 0.62-0.78; P < .0001), and SupraPVI (HR, 0.68; 95% CI, 0.52-0.89; P = .0045) but not after SUPRA bypass or AMP. CONCLUSIONS: Contrary to the published data for other forms of cardiovascular disease, African American patients as well as patients identified with Hispanic/Latino ethnicity with PAD included in the Society for Vascular Surgery Vascular Quality Initiative undergoing INFRA revascularization for lower extremity PAD experienced better overall survival compared with white Americans.

Primary health care for people with an intellectual disability: an exploration of consultations, problems identified, and their management in Australia.

BACKGROUND: People with an intellectual disability (ID) have more complex and different patterns of health care needs than the general population. They experience a greater burden of multi-morbidity, high levels of undetected and unmanaged health issues, and premature mortality than the general population. Primary care has a key role in the health care of people with an ID. Currently, very little is known about the consultation type and length, problems managed, and how general practitioners (GPs) manage these problems for people with an ID compared with the general population. This information would provide valuable insights into how GPs are achieving the health guidelines and facilitating people with an ID to achieve the highest attainable standard of health. METHODS: A secondary analysis of data was collected from January 2003 to December 2012 from the Bettering the Evaluation and Care of Health (BEACH) programme. Consultation type, consultation length in minutes, problem(s) managed during the consultation, medications, treatments provided, and referrals made, pre and post age-sex standardisation, at all GP encounters with people identified in the encounter record as having an ID ('ID' encounters, n = 690) were compared with those at 'non-ID' encounters (n = 970 641). Statistical significance was tested with 95% confidence intervals. RESULTS: This study identified significant differences in consultation types, consultation length, problem(s) managed during the consultation, medications, treatments provided, and referrals made at 'ID' encounters compared with 'non-ID' encounters. 'ID' encounters had more indirect encounters, longer consultations, more problems managed, but an under management of common health conditions in people with an ID. Administrative rather than medically related actions dominated clinical treatments for people at 'ID' encounters, and they received fewer procedural treatments, referrals to specialists, and medications compared with those at 'non-ID' encounters. CONCLUSION: The significant differences in consultations, problems identified and managed suggest that GPs may require additional support to (1) identify and manage common medical conditions experienced by people with an ID; (2) manage the increased time required for consultations; and (3) directly consult with people with an ID. Further research is required to determine why GPs managed problems in a significantly different way for people with an ID.

Predicting outcomes for infrapopliteal limb-threatening ischemia using the Society for Vascular Surgery Vascular Quality Initiative.

OBJECTIVE: The outcomes of open surgical or endovascular intervention for limb-threatening ischemia (LTI) involving the infrapopliteal vessels are dependent on complex anatomic, demographic, and disease factors. To assist in decision-making, we used the Vascular Quality Initiative (VQI) to derive a model using only preoperatively available factors to predict important outcomes for open or endovascular revascularization. METHODS: National VQI data for the infrainguinal bypass and peripheral vascular intervention (PVI) modules were reviewed in a blinded fashion for patients who underwent intervention for LTI of the infrapopliteal vessels. Primary outcomes consisted of major adverse limb event (MALE) and amputation-free survival (AFS). Generalized linear modeling was used for the multivariate analyses, with entry of variables dependent on results of univariate analysis. RESULTS: From January 2003 through August 2014 a total of 19,053 infrainguinal open bypass and 48,739 PVI procedures were identified, among which 5264 and 5252, respectively, represented infrapopliteal (tibial-peroneal-pedal) revascularization for LTI. From these, 3036 infrapopliteal open bypass patients and 1319 infrapopliteal PVI patients had sufficient follow-up data for study inclusion. For open surgery, the reduced generalized linear model revealed that American Society of Anesthesiologists class 4 or 5, previous major amputation, living at home, and female sex had the greatest adverse effect on MALE, and dialysis dependence, low body mass index, and lack of great saphenous vein as a conduit had the greatest negative effect on AFS. For PVI, lesion length from 10 to 15 cm, treatment of three or more arteries, and classification other than A on the Trans-Atlantic Inter-Society Consensus demonstrated the largest adverse effects on MALE, and dialysis dependence, low body mass index, and congestive heart failure most negatively affected AFS. CONCLUSIONS: This study on a cross-section of patients selected for intervention in academic and community hospitals offers a "real world" glimpse of factors predictive of outcome. The VQI can be used to derive models that predict the outcomes of open surgical bypass or PVI for LTI involving the infrapopliteal vessels.

Primary health care for people with an intellectual disability: an exploration of demographic characteristics and reasons for encounters from the BEACH programme.

BACKGROUND: People with an intellectual disability (ID) have complex and different patterns of healthcare needs. Poor participation in primary health care contributes to the high levels of undetected and unmanaged health issues and premature deaths of people with an ID. Limited research is available on the characteristics of people with an ID, their reasons for consulting general practitioners (GPs), and if these differ to people without an ID. Gaining such insights may provide an avenue to better understand patterns of primary care use and potential gaps in usage by people with an ID given their complex health profile compared with people without an ID. METHOD: A secondary analysis of data collected January 2003 to December 2012 from The Bettering the Evaluation and Care of Health programme was used. Participant characteristics and their reasons for encounter, pre- and post-age-sex standardisation, at all GP encounters with people identified in the encounter record as having an ID ('ID' encounters, n = 690) were compared with those at 'non-ID' encounters (n = 970 641). Statistical significance was tested with chi-squared statistics or 95% confidence intervals as appropriate. RESULTS: This study identified significant differences in participant characteristics and their reasons for consulting GPs at ID encounters compared with non-ID encounters. Participants at ID encounters had a skewed demography, an over-representation of presentations for psychological, social and 'general and unspecified' reasons, and an under-representation of presentations for core physical health and preventive health measures. Administrative rather than medically related reasons dominated presentations to general practice at ID encounters. CONCLUSION: There are significant differences in the characteristics of participants and their reasons for presentation to general practice in Australia for participants at ID encounters compared with non-ID encounters. This work suggests that there is a difference in service use patterns between these two groups. These findings may suggest that people with an ID experience barriers to participating in essential primary healthcare services.

The infraclavicular approach for venous thoracic outlet syndrome.

Venous thoracic outlet syndrome (vTOS) is an esoteric condition that presents in young, healthy adults. Treatment includes catheter-directed thrombolysis, followed by first-rib resection for decompression of the thoracic outlet. Various techniques for first-rib resection have been described with successful outcomes. The infraclavicular approach is well-suited to treat the most medial structures that are anatomically relevant for vTOS. A narrative review was conducted to specifically examine the literature on infraclavicular exposure for vTOS. The technique for this operation is described, as well as the advantages and disadvantages of this approach. The infraclavicular approach is a reasonable choice for definitive treatment of uncomplicated vTOS.

Endovascular stenting of external iliac vein injury during anterior spine exposure.

Anterior lumbar interbody fusion (ALIF) is a standard approach for the surgical management of patients with severe degenerative disease at the L4-L5 and lumbosacral (L5-S1) levels. ALIF is performed through retroperitoneal exposure but harbors a small risk of major vascular injury. In this case, we describe an emergent endovascular repair of an external iliac vein injury that occurred during ALIF with long-term follow-up. We discuss specific strategies in the decision making and technique that led to a successful outcome in this case. Endovascular stent grafting is a potential bailout option for serious iliac vein injury.

Open management of complex infrarenal aortic occlusive disease.

Open aortic reconstruction for complex aortoiliac occlusive disease is a time-honored and durable solution. Symptoms manifest as disabling claudication or chronic limb threatening ischemia in patients with multilevel disease. Advanced endovascular techniques have supplanted a large volume of aortic surgery. Nonetheless, it is essential for surgeons-in-training to learn and hone their skills in open aortic surgery. Comprehensive literature review over the past 50 years was conducted on the topics of "aortic occlusive disease," "aortic bypass," and "iliofemoral bypass." Pertinent articles were selected for inclusion as references. The technical aspects of the various aortoiliac exposures are described and selected case images were chosen from the senior author's experience. This review paper details the various operative approaches to open aortoiliac revascularization with emphasis on "tips and tricks" for the learner.

Quantifying the Differences between 3D Virtual Planning and Attained Postoperative Reduction on CT for Patients with Tibial Plateau Fractures; a Clinical Feasibility Study.

Background: Three-Dimensional Virtual Planning (3DVP) has been proven to be effective for limiting intra-articular screw penetration and improving the quality of reduction for numerous fractures. However, the value of 3DVP for patients with tibial plateau fractures has yet to be determined. Purposes: The research question of this study is: Can Computed Tomography Micromotion Analysis (CTMA) provide a reliable quantification of the difference between 3DVP and the postoperative reduction on CT for tibial plateau fractures? Methods: Nine consecutive adult patients who received surgical treatment for a tibial plateau fracture and received pre- and postoperative CT scans were included from a level I trauma center in the Netherlands. The preoperative CT scans of the patients were uploaded in a 3DVP software. In this software, fracture fragments were reduced and the reduction was saved as a 3D file (STL). The quality of the reduction from the 3DVP software was compared with the postoperative results using CT Micromotion Analysis (CTMA). In this analysis, the translation of the largest intra-articular fragment was calculated by aligning the postoperative CT with the 3DVP. Coordinates and measurement points were defined in the X, Y, and Z axes. The combined values of X and Y were used to define the intra-articular gap. The Z-axis was defined as the line from cranial to caudal and was used to define intra-articular step-off. Results: The intra-articular step-off was 2.4 mm (Range 0.5-4.6). Moreover, the mean translation of the X-axis and Y-axis, which was defined as the intra-articular gap, was 4.2 mm (Range 0.6-10.7). Conclusions: 3DVP provides excellent insight into the fracture and its fragments. Utilizing the largest intra-articular fragment, it is feasible to quantify the difference between 3DVP and a postoperative CT using CTMA. A prospective study to further analyze the use of 3DVP in terms of intra-articular reduction and surgical and patient-related outcomes has been started by our team.

The Journal Club 3.0: A qualitative, multisite study examining a new educational paradigm in the era of open educational resources.

BACKGROUND: The journal club is a ubiquitous and time-honored tradition within medical education. However, in recent years, open educational resources (OERs) have become increasingly influential in how physicians interact with the medical literature across multiple specialties. The authors sought to explore how emergency medicine (EM) resident physicians reconcile different perspectives across OERs into their educational experience at the journal club. METHODS: From January 2018 to September 2019, the authors enrolled 25 EM residents from four teaching sites associated with the University of British Columbia, Canada, to participate in either a focus group (seven residents) or individual interviews (18 residents). The authors used a snowball sampling technique. Using a constructivist grounded theory analysis, two investigators independently reviewed transcripts, meeting regularly to discuss themes until sufficiency was achieved. RESULTS: The study data expand the theoretical understanding of the resident journal club experience. Residents used multiple sources including OERs to learn about new evidence in the specialty. The rise of OERs helped residents to focus on developing critical appraisal skills and social bonds during the journal club. The local journal club gained a new relevancy in acting as a quality control mechanism against the premature adoption of research findings discussed in OERs. DISCUSSION: To date, most educators assume that residents prepare for a journal club by reading the selected articles and applying knowledge from their previous education. Instead, our findings suggest a more dynamic experience that integrates OERs. OERs enhance the journal club experience by allowing junior residents to more easily participate in discussions and to broaden the discussion to multiple clinical settings. Understanding these processes could inform future educational strategies around the journal club.
