Association of depression and anxiety disorders with outcomes after revascularization in chronic limb-threatening ischemia hospitalizations nationwide.

OBJECTIVE: Patients with chronic limb-threatening ischemia (CLTI), the end stage of peripheral artery disease, often present with comorbid depression and anxiety disorders. The prevalence of these comorbidities in the inpatient context over time, and their association with outcomes after revascularization and resource usage is unknown. METHODS: Using the 2011 to 2017 National Inpatient Sample, two cohorts were created-CLTI hospitalizations with endovascular revascularization and CLTI hospitalizations with surgical revascularization. Within each cohort, the annual prevalence of depression and anxiety disorder diagnoses was determined, and temporal trends were evaluated using the Cochran-Mantel-Haenszel test. Hierarchical multivariable logistic and linear regression analyses were used to examine the association of depression and anxiety disorder diagnoses with inpatient major amputation, mortality, length of stay (LOS), and cost, adjusting for illness severity, comorbidities, and potential bias in the documentation of depression and anxiety disorder diagnoses stratified by patient sociodemographic data. RESULTS: Across the study period were a total of 245,507 CLTI-related hospitalizations with endovascular revascularization and 138,922 with surgical revascularization. Hospitalizations with a depression or anxiety disorder diagnosis increased from 10.8% in 2011 to 15.3% in 2017 in the endovascular revascularization cohort and from 11.7% in 2011 to 14.4% in 2017 in the surgical revascularization cohort (Ptrend < .001). In the endovascular revascularization cohort, depression was associated with higher odds of major amputation (odds ratio, 1.15; 95% confidence interval, 1.03-1.30). In addition, depression (9 vs 8 days [P < .001]; $105,754 vs $102,481 [P = .018]) and anxiety disorder (9 vs 8 days [P < .001]; $109,496 vs $102,324 [P < .001]) diagnoses were associated with a longer median LOS and higher median costs. In the surgical revascularization cohort, depression was associated with a higher odds of major amputation (odds ratio, 1.33; 95% confidence interval, 1.13-1.58) and a longer LOS (median, 9 vs 9 days; P = .004). CONCLUSIONS: Depression and anxiety disorder diagnoses have become increasingly prevalent among CLTI hospitalizations including revascularizations. When present, these psychiatric comorbidities are associated with an increased risk of amputation and greater resource usage.

The Effect of Arterial Disease Level on Outcomes of Supervised Exercise Therapy for Intermittent Claudication: A Prospective Cohort Study.

OBJECTIVE: To assess whether level of arterial obstruction determines the effectiveness of SET in patients with IC. BACKGROUND DATA: Guidelines advocate SET before invasive treatment for IC, but early revascularization remains widespread, especially in patients with aortoiliac disease. METHODS: Patients were recruited from 10 Dutch centers between October 2017 and October 2018. Participants received SET first, followed by endovascular or open revascularization in case of insufficient effect. They were grouped according to level of stenosis (aortoiliac, femoropopliteal, multilevel, or rest group with no significant stenosis). Changes from baseline walking performance (maximal and functional walking distance on a treadmill test, 6-minute walk test) and vascular quality of life questionnaire-6 at 3 and 6 months were compared, after multivariate adjustment for possible confounders. Freedom from revascularization was estimated with Kaplan-Meier analysis. RESULTS: Some 267 patients were eligible for analysis (aortoiliac n = 70, 26%; femoropopliteal n = 115, 43%; multilevel n = 69, 26%; rest n = 13, 5%). No between group differences in walking performance or vascular quality of life questionnaire-6 were found. Mean improvement in maximal walking distance after 6 months was 439 m [99% confidence interval (CI) 297-581], 466 m (99% CI 359-574), 353 m (99% CI 210-496), and 403 m (99% CI 58-749), respectively (P = 0.40). Freedom from intervention was 73.9% for aortoiliac disease and 88.6% for femoropopliteal disease (hazard ratio 2.46, 99% CI 0.96 - 6.30, P = 0.013). CONCLUSIONS: Short-term effectiveness of SET for IC is not determined by the location of stenosis. Although aortoiliac disease patients improved walking performance and health-related quality of life similarly compared to other arterial disease level groups, they underwent revascularization more often.

Open Preperitoneal Inguinal Hernia Repair, TREPP Versus TIPP in a Randomized Clinical Trial.

OBJECTIVE: The aim of this study was to compare chronic postoperative inguinal pain (CPIP) in patients with an inguinal hernia after the TransREctus Sheath PrePeritoneal (TREPP) and the TransInguinal PrePeritoneal Technique (TIPP). BACKGROUND: The preperitoneal mesh position for inguinal hernia repair showed beneficial results regarding CPIP with low recurrence rates. Two open preperitoneal techniques, TREPP and TIPP, were compared in a randomized clinical trial with the hypothesis of fewer patients with CPIP after TREPP due to complete avoidance of nerve contact. METHODS: Adult patients with a primary unilateral inguinal hernia were randomized to either TREPP or TIPP in four hospitals. Before the trial's start the study protocol was ethically approved and published. Outcomes included CPIP after 1 year (primary outcome) and recurrence rates, adverse events, and health-related quality of life (secondary outcomes). Follow-up was performed at 2 weeks, 6 months, and 1 year. RESULTS: Baseline characteristics were comparable in both groups. Pain was less often present after TREPP at 2 weeks and 6 months, but CPIP at rest at 1 year was comparable: 1.9% after TREPP vs 1.4% after TIPP, P = 0.535). The overall recurrence rate was higher in the TREPP group, 8.9% vs 4.6%, P = 0.022). Corrected for a learning curve for TREPP, no significant difference could be assessed (TREPP 5.7% and TIPP 4.8%, P = 0.591). CONCLUSION: Both the TREPP and TIPP technique resulted in a low incidence of CPIP after 1-year follow-up. The TREPP method can be considered a solid method for inguinal hernia repair if expertise is present. The learning curve of the TREPP techniques needs further evaluation. TRIAL REGISTRATION: ISRCTN18591339.

Editor's Choice - A Systemic Evaluation of the Costs of Elective EVAR and Open Abdominal Aortic Aneurysm Repair Implies Cost Equivalence.

OBJECTIVE: The suggested high costs of endovascular aneurysm repair (EVAR) hamper the choice of insurance companies and financial regulators for EVAR as the primary option for elective abdominal aortic aneurysm (AAA) repair. However, arguments used in this debate are impeded by time related aspects such as effect modification and the introduction of confounding by indication, and by asymmetric evaluation of outcomes. Therefore, a re-evaluation minimising the impact of these interferences was considered. METHODS: A comparative analysis was performed evaluating a period of exclusive open repair (OR; 1998-2000) and a period of established EVAR (2010-2012). Data from four hospitals in The Netherlands were collected to estimate resource use. Actual costs were estimated by benchmark cost prices and a literature review. Costs are reported at 2019 prices. A break even approach, defining the costs for an endovascular device at which cost equivalence for EVAR and OR is achieved, was applied to cope with the large variation in endovascular device costs. RESULTS: One hundred and eighty-six patients who underwent elective AAA repair between 1998 and 2000 (OR period) and 195 patients between 2010 and 2012 (EVAR period) were compared. Cost equivalence for OR and EVAR was reached at a break even price for an endovascular device of €13 190. The main cost difference reflected the longer duration of hospital stay (ward and Intensive Care Unit) of OR (€11 644). Re-intervention rates were similar for OR (24.2%) and EVAR (24.6%) (p = .92). CONCLUSION: Cost equivalence for EVAR and OR occurs at a device cost of €13 000 for EVAR. Hence, for most routine repairs, EVAR is not costlier than OR until at least the five year follow up.

Gentamicin Containing Collagen Implants and Groin Wound Infections in Vascular Surgery: A Prospective Randomised Controlled Multicentre Trial.

OBJECTIVE: The aim of this study was to assess the effectiveness of gentamicin containing collagen implants in the reduction of surgical site infections (SSIs) in patients undergoing an inguinal incision for vascular surgery. METHODS: Prospective blinded randomised controlled multicentre trial (RCT), performed in four hospitals in The Netherlands and Belgium. This study included 288 patients who underwent an inguinal incision for primary arterial repair (femoral endarterectomy, femorofemoral or femoropopliteal bypass, aortobifemoral bypass, thrombectomy, embolectomy, endovascular aneurysm repair) between October 2012 and December 2015. Patients were randomised to receive a gentamicin implant (study group) or no implant (control group). The calculated sample sizes of 304 patients per group were not reached. Primary outcome was SSI incidence after six weeks. Secondary outcomes were time to onset of infection, length of hospital stay, allergic reactions, treatment with antibiotics, need for re-admission, re-operation and mortality. RESULTS: One hundred fifty-one patients were allocated to the study group (mean age 69 ± 9.2 years) and 137 patients were allocated to the control group (mean age 70 ± 10.4 years). Both groups were homogeneous regarding baseline and intra-operative characteristics. Gentamicin implants did not result in a significant overall reduction of SSIs in the study group (7% vs. 12%, p = .17). In a post hoc analysis comparing two study sites with low (<10%) and two study sites with high (>10%) infection rates in the control group, gentamicin implants significantly reduced SSIs in high risk centres (22% vs. 1%, p < .001), whereas there was no significant effect in low risk centres (13% vs. 7%, p = .30). There were no allergic reactions and all secondary outcomes were comparable between groups. CONCLUSION: Gentamicin implants did not result in a significant overall reduction of SSIs in this RCT. Gentamicin implants did reduce the incidence of SSIs in high risk centres and may be a valuable adjunct to improve outcomes in such vascular centres with a high incidence of wound infections. However, the limitation of not reaching the calculated sample sizes should be considered.

A Comparison of Quality of Life in Elderly Patients with Intermittent Claudication and Chronic Limb-Threatening Ischemia.

BACKGROUND: Intermittent claudication (IC) and chronic limb-threatening ischemia (CLTI) are both associated with a decreased health status and possibly quality of life (QOL). A better understanding of the differences in QOL between patients with IC and CLTI could be of additional value in shared decision-making. The aim of this study was to compare the QOL at baseline between patients with IC and patients with CLTI. METHODS: The study population was based on 2 study cohorts, 1 cohort consisted of patients with IC (ELECT registry) and the other cohort of patients with CLTI (KOP-study). Patients with an age of ≥70 years were included. QOL at baseline was measured by the WHOQOL-BREF questionnaire. Nonresponders were excluded from data analyses. Student's t-tests and analysis of covariance (ANCOVA) analyses were used to compare QOL between the 2 groups. Outcomes of the ANCOVA analyses were expressed as estimated marginal means. RESULTS: In total, 308 patients were included, 115 patients with IC and 193 patients with CLTI. Patients with CLTI were older (median age 80 years vs. 75 years, P < 0.001) and had more comorbidities. Patients with IC had a statistically significant higher QOL regarding physical health (mean 13.7 [standard deviation (SD) 2.3] vs. 10.8 [SD 2.8], P < 0.001), psychological health (mean 15.3 [SD 2.1] vs. 14.1 [SD 2.4], P < 0.001), environment (mean 16.3 [SD 2.4] vs. 15.5 [SD 2.0], P < 0.002), and the overall domain (mean 3.5 [SD 0.7] vs. 3.1 [SD 0.9], P < 0.001). After correcting for the confounding effect of age and sex, patients with IC still had a statistically significant higher QOL in the physical, psychological, environment, and overall domain. CONCLUSIONS: Patients with IC had a significantly higher QOL in the physical, psychological, environment, and overall domains of the WHOQOL-BREF questionnaire compared with patients with CLTI. This underlines the importance of strategies that reduce disease progression as disease progression is associated with a decrease in QOL.

Penetrating Neck Injury in Two Dutch Level 1 Trauma Centres: the Non-Existent Problem.

OBJECTIVES: Penetrating neck injuries (PNIs) have a low incidence in European trauma populations. Selective non-operative management of PNI has been suggested as a safe alternative to standard surgical neck exploration, but evidence is lacking. This clinical scenario evaluates institutional PNI management, specifically the associated carotid artery injury, and compares it with current guidelines. METHODS: Retrospectively, PNI patients presenting at two Dutch level 1 trauma centres from 2007 to 2015, were identified. International guidelines on PNI management were reviewed and recommendations were assessed in relation to current institutional management, and considering an illustrative case. RESULTS: Two current guidelines on PNI management were reviewed. Both advocate a zone based approach; one recommends a prominent role for computed tomography angiography (CTA) scanning in stable patients, supplemented by endoscopy when indicated. A combined total of 43 PNI patients were identified over a nine year period. Haemodynamically unstable patients and patients with other hard signs (i.e. active bleeding, expanding haematoma, air/saliva leak, massive subcutaneous emphysema) received immediate exploration (n = 9). Haemodynamically stable patients and those responding to resuscitation (transient responders) had a CTA scan (n = 31). Three asymptomatic patients were treated conservatively, and had an uncomplicated clinical course regarding the PNI. In 10 of 14 patients who received surgical exploration, a significant vascular or aerodigestive injury was found and repaired (71%). All patients treated conservatively after CTA scanning had an uncomplicated clinical course regarding the PNI (n = 17). Six patients with penetrating carotid artery injury underwent primary arterial reconstruction, of whom five survived. CONCLUSIONS: This clinical scenario evaluates institutional management in two trauma centres for PNI and associated carotid artery injury, and compares it to current guidelines. In comparison with guideline recommendations, CTA scanning and the so called "No zone" approach appears to have assumed a more prominent role in management of PNI.

Evolution of Computed Tomography Imaging the First Year after Endovascular Sealing of Infrarenal Aortic Aneurysms Using the Nellix Device.

BACKGROUND: The Nellix endovascular aneurysm sealing (EVAS) system is an alternative endovascular treatment option for infrarenal aortic aneurysms (AAAs), with a unique appearance on computed tomography angiography (CTA). Normal evolution of post-EVAS CTA appearance follow-up is still largely unknown and important to timely detect eventual complications. The objective is to assess the normal appearance of CTA images 30 days and 1 year after EVAS in 50 consecutive patients. METHODS: Fifty patients treated with Nellix EVAS for an infrarenal AAA were included from 3 hospitals. Using dedicated software, a total of 150 CTA scans were analyzed by predetermined variables per anatomical segment. RESULTS: Thirty days post-EVAS, there was a slight, but not statistically significant, increase in AAA diameter that returned to the preoperative value after 1 year. A shift in total aortic volume distribution was observed without changing aortic diameter, including a trend toward a decreased thrombus volume (85.6 ± 49.1 mL and 78.8 ± 35.5 mL at 30 days and 1 year, respectively, P < 0.242) and a slight, but statistically significant, increase in polymer volume (68.2 ± 34.1 mL and 71.9 ± 35.2 mL at 30 days and 1 year, respectively, P < 0.001). The ß-angle (P = 0.06) and iliac artery angulation (P < 0.001) decreased after implant. The latter returned to its original state after 1 year, whereas the neck straightening remained. Over time, there was a significant decrease in radiodensity in the middle of the polymer-filled endobags with an increase at its edges (P < 0.05). Thrombus radiodensity significantly increased over the first year (P < 0.05). Diameters of the infrarenal neck and common iliac arteries remained unchanged, no endoleaks were observed, and the position of the device was stable. CONCLUSIONS: Change of CT appearance after EVAS is unique, and as such, the judgment of these images requires experience. The appearance of the endobags in respect to volume and radiodensity differ from classic EVAR. Normal changes over time are observed in aortoiliac angulation, volumes, and radiodensities.

Determinants of invasive treatment in lower extremity peripheral arterial disease.

OBJECTIVE: Since it is unknown what factors are weighed in a clinician's decision to refer patients with symptomatic lower extremity peripheral arterial disease (PAD) for invasive treatment, we examined the relationship between health status, lesion location, and site variations and invasive treatment referral ≤1 year following diagnosis in patients with PAD. METHODS: This was a prospective observational cohort study on ambulatory patients that presented themselves at two vascular surgery outpatient clinics. A total of 970 patients with new symptoms of PAD or with an exacerbation of existing PAD symptoms that required clinical evaluation and treatment (Rutherford Grade I) were eligible, 884 consented and were included between March 2006 and November 2010. We report on 505 patients in the current study. Prior to patients' initial PAD evaluation, the Short Form-12, Physical Component Scale (PCS) was administered to measure health status. Anatomical lesion location (proximal vs distal) was derived from duplex ultrasounds. PCS scores, lesion location, and site were evaluated as determinants of receiving invasive (endovascular, surgery) vs noninvasive treatment ≤1 year following diagnosis in Poisson regression analyses, adjusting for demographics, ankle-brachial index, and risk factors. RESULTS: Invasive treatment as a first-choice was offered to 167 (33%) patients. While an association between poorer health status and invasive therapy was found in unadjusted analyses (relative risk [RR], 0.98; 95% confidence interval [CI], 0.97-1.00; P = .011), proximal lesion location (RR, 3.66; 95% CI, 2.70-4.96; P < .0001) and site (RR, 1.69; 95% CI, 1.11-2.58; P = .014) were independent predictors of invasive treatment referral in the final model. CONCLUSIONS: One-third of patients were treated invasively following PAD diagnosis. Patients' health status was considered in providers' decision to refer patients for invasive treatment, but having a proximal lesion was the strongest predictor. This study also found some important first indications of site variations in offering invasive treatment among patients with PAD. Future work is needed to further document these variations in care.

Report of two in situ reconstructions with a saphenous spiral vein graft of Coxiella burnetii-infected aneurysms of the abdominal aorta.

Coxiella burnetii is a rare cause of vascular infections. Yet, Q fever is endemic in the southern part of The Netherlands. This report describes two patients--from the southern part of The Netherlands--with infected aneurysms of the abdominal aorta caused by Coxiella burnetii. Both patients underwent surgical debridement, in situ reconstruction with a great saphenous vein spiral graft, and a transmesenteric omentumplasty. One patient fully recovered, while the other died due to ischemic complications. A multidisciplinary work-up approach to treat infected abdominal aneurysms is proposed, including adequate surgical treatment and long-term antibiotic administration.

A shift toward endovascular repair for vascular complications in lumbar disc surgery during the last decade.

BACKGROUND: The purpose of this study is to evaluate 2 patients who underwent endovascular repair directly after acute life-threatening vascular injury complicating lumbar disc surgery, and to update an overview of the literature from 2002 to gain insights into characteristics, diagnosis, treatment, and outcomes of this rare, life-threatening complication. METHODS: PubMed was searched for English language studies on vascular injury (lacerations, arteriovenous fistulas, and pseudoaneurysms) complicating lumbar disc surgery by a posterior approach published from 2002. Two cases from the authors' institute were added to the review. Information on patient characteristics, diagnosis, treatment strategies, and outcomes were extracted by 2 independent reviewers. CASE REPORTS: The first case describes a 54-year-old man who underwent lumbar disc surgery through a posterior approach (L5-S1) and became hypotensive intraoperatively. Angiography revealed an injury of the right internal iliac artery. Bleeding was successfully repaired by endovascular repair (acute balloon occlusion followed by coiling). The second case describes a 51-year-old women who suddenly became hypotensive during L4 through L5 discectomy caused by bleeding from a laceration in the right common iliac artery. Angiography confirmed the diagnosis, and the bleeding was successfully treated through endovascular repair with a covered stent. RESULTS: A total of 56 cases from 34 articles were found in the literature since 2002, including lacerations, arteriovenous fistulas, and pseudoaneurysms. Two cases from the authors' institute were added to the review. Vascular injury was recognized intraoperatively in 36%, and within 24 hours postsurgery in 28%. The common iliac artery was most frequently affected (51%), followed by the iliac vein (23%). All lacerations were detected during surgery, whereas most arteriovenous fistulas and pseudoaneurysms were detected in the long term. Treatment consisted of open surgical repair (57%) or endovascular repair (43%). All patients survived surgery. CONCLUSIONS: Publication bias might play a role in the literature of this area because all cases survived surgery, whereas mortality rates for this condition are high. However, early recognition, diagnosis, and prompt surgical repair are essential to prevent fatal outcomes in vascular injuries complicating lumbar disc surgery. Endovascular repair is a minimally invasive, fast, and efficient treatment modality that is increasingly and preferably used because of its low morbidity and mortality.

Histological evaluation of the aortic wall response following endovascular aneurysm repair and endovascular aneurysm sealing.

Objective: The Nellix endovascular aneurysm sealing (EVAS) system was developed as an alternative to conventional endovascular aneurysm repair (EVAR) to minimize endoleaks. A significantly higher failure rate of EVAS may be related to an interaction between the filled endobags and the AAA wall. In general, biological information on aortic remodeling after traditional EVAR is scarce. In this light, we provide here the first histologic evaluation of aneurysm wall morphology after EVAR and EVAS. Methods: Fourteen histological human wall samples of EVAS and EVAR explantation were systematically analysed. Primary open aorta repair samples were included as reference. Results: Compared with primary open aortic repair samples, endovascular repair aortic samples were characterized by more pronounced fibrosis, a greater number of ganglionic structures, decreased cellular inflammation, less calcification, and a lower atherosclerotic load. EVAS was specifically associated with the presence of unstructured elastin deposits. Conclusions: The biological response of the aortic wall after endovascular repair resembles the maturation process of a scar rather than a bona fide healing response. Moreover, the inflammatory response in the aortic wall after placement of endovascular protheses is less prominent than after primary open repair. A specific post-EVAS aortic wall characteristic was unstructured elastin fragments.

The association of depression with mortality and major adverse limb event outcomes in patients with peripheral artery disease: A systematic review and meta-analysis.

BACKGROUND: Peripheral artery disease (PAD) is highly prevalent and associated with poor outcomes. Depression is a risk factor for adverse outcomes in patients with coronary artery disease. Despite evidence showing that depression is common in patients with PAD, less is known about its association with adverse prognostic outcomes. To address this, we conducted a systematic review and meta-analysis to summarize the association between depression and outcomes in patients with PAD. METHODS: We performed a systematic search of eight databases to January 2022 including studies that reported a risk estimate for the association of depression or depressive symptoms with all-cause mortality or major adverse limb events (MALE) in patients with PAD and pooled results in a meta-analysis. Risk of bias was assessed using ROBINS-I. RESULTS: Of the 7048 articles screened, 5 observational studies with 119,123 patients were included. A total of 16.2 % had depression or depressive symptoms. Depression was associated with a statistically significant increased risk of all-cause mortality (HR 1.24, confidence interval 1.07-1.25, p = .005). The association between depression and MALE was not significant but trended toward a positive association. LIMITATIONS: Due to lack of data, results were limited by a single study with a large sample size, overrepresentation of men, and lack of information of depression severity or treatment status. CONCLUSION: Depression or depressive symptoms are associated with a 24 % increased risk of all-cause mortality in patients with PAD. Future work should explore the mechanisms and directionality of this association and identify depression as an important comorbidity to address for patients with PAD.

Eversion technique versus traditional carotid endarterectomy with patch angioplasty: a systematic review with meta-analyses and trial sequential analysis.

Introduction: The use of an 'eversion' technique is not unequivocally proven to be superior to carotid endarterectomy with patch angioplasty. An up-to-date systematic review is needed for evaluation of benefits and harms of these two techniques. Methods: RCTs comparing eversion technique versus endarterectomy with patch angioplasty in patients with a symptomatic and significant (≥50 %) stenosis of the internal carotid artery were enrolled. Primary outcomes were all-cause mortality rate, health-related quality of life and serious adverse events. Secondary outcomes included 30-day stroke and mortality rate, (a) symptomatic arterial occlusion or restenosis, and adverse events not critical for decision making. Results: Four RCTs were included with 1272 surgical procedures for carotid stenosis; eversion technique n = 643 and carotid endarterectomy with patch closure n = 629. Meta-analysis comparing both techniques showed, with a very low certainty of evidence, that eversion technique might decrease the number of patients with serious adverse events (RR 0.47; 95% CI 0.34 to 0.64; p ≤ 0.01). However, no difference was found on the other outcomes. TSA demonstrated that the required information sizes were far from being reached for these patient-important outcomes. All patient-relevant outcomes were at low certainty of evidence according to GRADE. Conclusions: This systematic review showed no conclusive evidence of any difference between eversion technique and carotid endarterectomy with patch angioplasty in carotid surgery. These conclusions are based on data obtained in trials with very low certainty according to GRADE and should therefore be interpreted cautiously. Until conclusive evidence is obtained, the standard of care according to ESVS guidelines should not be abandoned.

Self-reported symptoms on questionnaires and anatomic lesions on duplex ultrasound examinations in patients with peripheral arterial disease.

OBJECTIVE: Whether a typical patient and symptom profile is associated with proximal or distal lesions in lower extremity peripheral arterial disease (PAD) is unknown. Knowing which patient characteristics, exertional leg symptoms, and cardiovascular risk profile accompany the anatomic lesion location may facilitate a more tailor-made management of PAD. METHODS: This cross-sectional study comprised 701 patients from two vascular surgery outpatient clinics with new-onset symptoms of PAD (Fontaine 2) who underwent duplex ultrasound (DUS) examinations from March 2006 to March 2011. The main outcome measures were patient characteristics, self-reported leg symptoms, and cardiovascular risk factors as documented from questionnaires and medical records. Peripheral lesion information, categorized by proximal and distal lesions, was obtained from DUS examinations. Multivariable logistic regression analyses were performed of proximal vs nonproximal lesions, distal vs nondistal lesions, and proximal and distal vs absence of having both lesions to assess relationships between patient characteristics, leg symptom categories (typical vs atypical leg symptoms), cardiovascular risk factors, and anatomic lesion location. RESULTS: Lesions were proximal in 270 (38.5%), distal in 441 (62.9%), and proximal and distal in 94 (13.4%). Patients with proximal lesions were younger (odds ratio [OR], 0.94; P < .0001) and less likely to be obese (OR, 0.34; P < .0001) than those without proximal lesions. Older age (OR, 1.07; P < .0001), male sex (OR, 1.96; P = .003), being without a partner (OR, 2.24; P = .004), and lower anxiety scores (OR, 0.42; P = .003) were associated with distal lesions. Patients with both lesions were more likely to be single (OR, 2.30; P = .010) and less likely to be obese (OR, 0.24; P = .009). No distinguishing leg symptom pattern was observed for patients with proximal lesions. Intermittent claudication was more frequently reported in those with distal lesions (P = .011). Although buttock and thigh pain seemed to be somewhat more present in proximal lesions (P < .01) and calf pain more in distal lesions (P < .001), patients still reported pain at a variety of levels throughout their legs, regardless of the anatomic lesion location. CONCLUSIONS: Two distinctive PAD phenotypes-each with its own characteristics and risk factors-emerged by anatomic lesion location; however, PAD-specific leg symptoms did not always reflect the anatomic lesion location. These findings may open new opportunities to better tailor PAD management to these two PAD subgroups and may raise awareness about not relying on self-reported symptoms to guide further diagnostic imaging and peripheral lesion management.

Infected abdominal aneurysm due to Salmonella sepsis: report of a unique case treated using the superficial femoral vein.

We describe a 61-year-old patient with an infected aneurysm of the abdominal aorta due to Salmonella sepsis. Treatment was successful and included aneurysm resection, extensive debridement, and reconstruction of the abdominal aorta using the superficial femoral vein, combined with long-term antibiotic therapy.

A histopathological classification scheme for abdominal aortic aneurysm disease.

OBJECTIVE: Two consensus histopathological classifications for thoracic aortic aneurysms (TAAs) and inflammatory aortic diseases have been issued to facilitate clinical decision-making and inter-study comparison. However, these consensus classifications do not specifically encompass abdominal aortic aneurysms (AAAs). Given its high prevalence and the existing profound pathophysiologic knowledge gaps, extension of the consensus classification scheme to AAAs would be highly instrumental. The aim of this study was to test the applicability of, and if necessary to adapt, the issued consensus classification schemes for AAAs. METHODS: Seventy-two AAA anterolateral wall samples were collected during elective and emergency open aneurysm repair performed between 2002 and 2013. Histologic analysis (hematoxylin and eosin and Movat Pentachrome) and (semi-quantitative and qualitative) grading were performed in order to map the histological aspects of AAA. Immunohistochemistry was performed for visualization of aspects of the adaptive and innate immune system, and for a more detailed analysis of atherosclerotic lesions in AAA. RESULTS: Because the existing consensus classification schemes do not adequately capture the aspects of AAA disease, an AAA-specific 11-point histopathological consensus classification was devised. Systematic application of this classification indicated several universal features for AAA (eg, [almost] complete elastolysis), but considerable variation for other aspects (eg, inflammation and atherosclerotic lesions). CONCLUSIONS: This first multiparameter histopathological AAA consensus classification illustrates the sharp histological contrasts between thoracic and abdominal aneurysms. The value of the proposed scoring system for AAA disease is illustrated by its discriminatory capacity to identify samples from patients with a nonclassical (genetic) variant of AAA disease.

Younger women with symptomatic peripheral arterial disease are at increased risk of depressive symptoms.

OBJECTIVES: Gender disparities, particularly among young women with cardiovascular disease, are a growing cause for concern. Depression is a prevalent and prognostically important comorbidity in peripheral arterial disease (PAD), but its prevalence has not been described as a function of gender and age. Therefore, we compared depressive symptoms at the time of PAD diagnosis and 6 months later by gender and age in PAD patients. METHODS: The study enrolled 444 newly diagnosed patients with PAD (32% women) from two Dutch vascular outpatient clinics. Patients' depressive symptoms were assessed with the 10-item Center for Epidemiological Studies Depression Scale (CES-D) at baseline and 6 months later (CES-D scores >or=4 indicate significant depressive symptoms). Logistic regression models were constructed to evaluate the relationship among four gender-age groups (women <65 and >or=65 years; men <65 and >or=65 years [reference category]) and baseline and 6-month follow-up depressive symptoms. RESULTS: Initially, 33% of women <65 years had significant depressive symptoms, and 6 months later, significant depressive symptoms had developed in 19% of the other younger women. These rates were much higher than other gender-age groups (range at baseline, 11%-16%; 6-month incidence, 6%-10%; P or=65 years, whereas other gender-age groups were not at risk. Additional adjustment for change in the ankle-brachial index did not explain the increased depression risk in younger women (OR, 3.5; 95% CI, 1.2-10.2). CONCLUSIONS: Significant depressive symptoms are more common in younger women with PAD than in other gender-age groups, both at the time of diagnosis and 6 months later. To eradicate gender-based disparities in PAD, depression screening and monitoring in younger women may be an important direction for future research and intervention.

Eagle Syndrome: A Unique Cause of Carotid Bleeding.

Eagle syndrome is a rare aggregate of symptoms caused by an elongated styloid process. We present the unique case of bilateral vascular Eagle syndrome in a patient who experienced a unilateral acute swelling due to bleeding at the level of the right internal carotid artery. This complication has never been described before. (Level of Difficulty: Advanced.).

Giant true hepatic aneurysm mimicking Mirizzi syndrome.

Giant true aneurysms of the hepatic arteries are rare. Pseudoaneurysms of the hepatic arteries are more common and are mostly caused by intra-abdominal infection, iatrogenic injury, or trauma. Hepatic or cystic pseudoaneurysms are often successfully treated by embolization owing to their saccular nature as opposed to true aneurysms. We present a case of a patient with a giant true aneurysm of the proper hepatic artery, mimicking Mirizzi syndrome. Open reconstruction was successfully preformed, and the patient made a full recovery.
