RESUMO

OBJECTIVES: Rotational atherectomy can offer a viable treatment for occlusive peripheral artery disease; maintaining the minimal invasiveness of an endovascular procedure, while allowing for a more complete lesion debridement compared with balloon angioplasty. This case report outlines a complication of guidewire entrapment associated with rotational atherectomy in the superficial femoral artery (SFA). METHODS: A 57-year-old male underwent an atherectomy with Rotorex for left lower limb foot pain. During the procedure, the guidewire was suctioned into the atherectomy device, preventing any further advancement of the device and damaging the SFA and posterior tibial artery (PTA). RESULTS: The atherectomy device was withdrawn and a new vascular access site was gained in the left PTA. A covered stent was inserted to treat the original SFA lesion, and balloon angioplasty was used to repair the device-induced damaged to the PTA. CONCLUSION: While guidewire complications have been previously reported, this case report details the first reported case, to our knowledge, of guidewire entrapment while using a rotational atherectomy device. Knowledge of this possible complication of rotational atherectomy can aid in clinical decision making when choosing between treatments for peripheral vascular disease.

RESUMO

OBJECTIVE: Cerebrovascular accidents (CVA) are potential sequelae of blunt cerebrovascular injuries (BCVI). To minimize their risk, medical therapy is used commonly. It is unclear if anticoagulant or antiplatelet medications are superior for decreasing CVA risk. It is also unclear as to which confer fewer undesirable side effects specifically in patients with BCVI. The aim of this study was to compare outcomes between nonsurgical patients with BCVI with hospital admission records who were treated with anticoagulant medications and those who were treated with antiplatelet medications. METHODS: We performed a 5-year (2016-2020) analysis of the Nationwide Readmission Database. We identified all adult trauma patients who were diagnosed with BCVI and treated with either anticoagulant or antiplatelet agents. Patients who were diagnosed with index admission CVA, intracranial injury, hypercoagulable states, atrial fibrillation, and or moderate to severe liver disease were excluded. Those who underwent vascular procedures (open and/or endovascular approaches) and or neurosurgical treatment were also excluded. Propensity score matching (1:2 ratio) was performed to control for demographics, injury parameters, and comorbidities. Index admission and 6-month readmission outcomes were examined. RESULTS: We identified 2133 patients with BCVI who were treated with medical therapy; 1091 patients remained after applying the exclusion criteria. A matched cohort of 461 patients (anticoagulant, 159; antiplatelet, 302) was obtained. The median patient age was 72 years (interquartile range [IQR], 56-82 years), 46.2% of patients were female, falls were the mechanism of injury in 57.2% of cases, and the median New Injury Severity Scale score was 21 (IQR, 9-34). Index outcomes with respect to (1) anticoagulant treatments followed by (2) antiplatelet treatments and (3) P values are as follows: mortality (1.3%, 2.6%, 0.51), median length of stay (6 days, 5 days; P < .001), and median total charge (109,736 USD, 80,280 USD, 0.12). The 6-month readmission outcomes are as follows: readmission (25.8%, 16.2%, <0.05), mortality (4.4%, 4.6%, 0.91), ischemic CVA (4.9%, 4.1%, P = not significant [NS]), gastrointestinal hemorrhage (4.9%, 10.2%, 0.45), hemorrhagic CVA (0%, 0.41%, P = NS), and blood loss anemia (19.5%, 12.2%, P = NS). CONCLUSIONS: Anticoagulants are associated with a significantly increased readmission rate within 6 months. Neither medical therapy is superior to one another in the reduction of the following: index mortality, 6-month mortality, and 6-month readmission with CVA. Notably, antiplatelet agents seem to be associated with increased hemorrhagic CVA and gastrointestinal hemorrhage on readmission, although neither association is statistically significant. Still, these associations underscore the need for further prospective studies of large sample sizes to investigate the optimal medical therapy for nonsurgical patients with BCVI with hospital admission records.

RESUMO

OBJECTIVE: Readmission after vascular procedures is a burden to hospitals and the Medicare system. Therefore, identifying risk factors leading to readmission is vital. We examined the frequency of and risk factors for 30-day readmission after open aneurysm repair (OAR) and explored post-operative outcomes with special attention for those with preexisting chronic kidney disease (CKD). METHODS: Patients who underwent OAR were identified in the National Readmission Database (2016-2018). Demographic information and comorbidities were collected. Patients readmitted within 30 days after their index hospitalization were identified and compared to patients without readmission records. RESULTS: A total of 5090 patients underwent OAR during the study timeframe with 488 patients (9.6%) were readmitted within 30 days. Females were more readmitted than males (F = 11.1% vs M = 9.0%, P < 0.001). Readmitted patients had more comorbidities (median ECI 12, P < 0.05), were on Medicare (73.7%, P < 0.001), had higher surgery admission cost ($146,844, P < 0.001), longer length of stay (8 days, P < 0.001), and were discharged to a lower level care facility (62.7%, P < 0.001). Comorbidities that predisposed patients for readmission include: peripheral arterial disease (OR 2.15, P < 0.01), asthma (OR 1.87, P < 0.01), chronic heart failure (OR 1.74, P < 0.05). On readmission visit, acute renal failure (23.8%) was the most common diagnosis, while intestinal surgery (13.7%) was the most common procedure. Patients with CKD (n = 968, 18.9% of total population) had double the mortality rate compared to non-CKD patients on surgery admission (10.4%, P < 0.001) and readmission (10.1%, P < 0.001). CONCLUSION: Certain factors were noted to increase readmission rate, special attention need to be paid when dealing with such group of patients requiring OAR. Vascular surgeons should meticulously weigh benefits and risks when considering OAR in patients with CKD who are not a candidate for endovascular repair, and optimize their kidney function before considering such approach.

RESUMO

OBJECTIVES: Non-traumatic lower extremity amputation (LEA) is associated with significant morbidity and mortality. Diabetes mellitus (DM) and peripheral vascular disease (PVD) are associated with increased risk for LEA. As such, DM and PVD account for 54% of all LEA's, performed in the United States annually. As obesity is highly associated with both DM and PVD, our study sought to explore the relationship between LEA and obesity defined by BMI. METHODS: Using the National Inpatient Sample (NIS) database, a retrospective review of patients who underwent non-traumatic LEA (LEA) between 2008 and 2014 was performed. The International Classification of Diseases 9th edition (ICD-9) codes were utilized to determine the diagnoses, comorbidities, and procedures. Patient BMIs were classified as follows: Non-obese [BMI <30], Obesity class I [BMI 30-34.9], Obesity class II [BMI 35-39.9], and Obesity class III [BMI ≥40]. Predictors for LEA were compared between groups using chi-square test and binary logistic regression to identify possible underlying factors associated with LEA. We also conducted a multivariate analysis to measure the effect of multiple variables on LEA. RESULTS: We identified 16,259 patients with non-traumatic LEA and a mean age of 59.9 years. Rate of amputation in females was lower than males at 0.35% vs 0.87% respectively (p < 0.001). Of patients that underwent amputation there was a V-shape trend based on BMI, with 30.4% in non-obese patients, 18.2% in obesity class I, 17.3% in obesity class II, and 34.1% in obesity class III. The incidence of diabetes increased with obesity class, while the incidence of PVD decreased. Interestingly, of those with DM there was an inverse relationship between amputation rate and BMI class, with LEA rates in non-obese versus obesity class III patients were 1.63% vs 0.98% respectively (p < 0.001). Similarly, patients who had both diabetes and PVD showed a downward trend in LEA rate as obesity class increased; non-obese patients had a LEA rate of 8.01%, while obesity class III had 4.65% (p < 0.001). Patients in higher income bracket have lower odds of LEA (OR 0.77, p < 0.001) compared to the lowest income patients. Also, patients with comorbidities such as PVD (OR 10.78), diabetes (OR 5.02), renal failure (OR 1.41), and hypertension (OR 1.36) had higher odds to get an LEA (p < 0.001). Individuals with obesity class III are almost at half the odds (OR 0.52) to get an LEA compared to non-obese (p < 0.001). CONCLUSIONS: Higher BMI and female gender are protective factors against lower extremity amputation. Factors that predisposing to LEA include lower household income and certain comorbidities such as PVD, diabetes, renal failure, and hypertension. These findings warrant further research to identify patients at high risk for LEA and help develop management guidelines for targeted populations.

RESUMO

BACKGROUND: The objective of this study was to create an algorithm that could predict diabetic foot ulcer (DFU) incidence in the in-patient population. MATERIALS AND METHODS: The Nationwide Inpatient Sample datasets were examined from 2008 to 2014. The International Classification of Diseases 9th Edition Clinical Modification (ICD-9-CM) and the Agency for Healthcare Research and Quality comorbidity codes were used to assist in the data collection. Chi-square testing was conducted, using variables that positively correlated with DFUs. For descriptive statistics, the Student T-test, Wilcoxon rank sum test, and chi-square test were used. There were six predictive variables that were identified. A decision tree model CTREE was utilized to help develop an algorithm. RESULTS: 326,853 patients were noted to have DFU. The major variables that contributed to this diagnosis (both with p < 0.001) were cellulitis (OR 63.87, 95% CI [63.87-64.49]) and Charcot joint (OR 25.64, 95% CI [25.09-26.20]). The model performance of the six-variable testing data was 79.5% (80.6% sensitivity and 78.3% specificity). The area under the curve (AUC) for the 6-variable model was 0.88. CONCLUSION: We developed an algorithm with a 79.8% accuracy that could predict the likelihood of developing a DFU.

RESUMO

OBJECTIVES: This study examined the current demographic and outcome trends regarding endovascular and open revascularization for people with diabetes. METHODS: The National Inpatient Sample database was utilized to identify diabetic patients who underwent lower extremity revascularization and amputation procedures between 2008 and 2014. International Classification of Diseases 9th edition codes were used to identify the procedures, diagnoses, and comorbidities. RESULTS: We identified 38,143 diabetic patients who underwent endovascular revascularization and 25,415 who underwent open revascularization between 2008 and 2014. The number of endovascular and open revascularization procedures decreased steadily by 17.5% and 12.43% during the study period, respectively. The total charges for the endovascular procedure were greater than the open procedure ($98,761 vs. $80,782, p ≤ 0.001) despite similar median length of stay (5 days (inner quartile range (IQR) = 1-10) vs. 5 days (IQR = 3-10), p ≤ 0.001). Compared to open, the in-patient amputation rate for endovascular patients has been increasing faster for both minor (11.75% vs. 0.37%) and major amputations (3.08% vs. 0.19%). Although the post-procedure amputation rates between endovascular and open procedures were increased for endovascular patients (odds ratio [OR] = 1.71, confidence interval [CI] = 1.35-2.18, p ≤ 0.001) in 2008, by 2014 the risk of major amputation was doubled in endovascular patients (OR = 2.88, CI = 2.27-3.64, p ≤ 0.001). African Americans were more likely to undergo minor amputation than Whites (p ≤ 0.001). Lastly, diabetic patients with uncontrolled diabetes, systemic infection, weight loss, congestive heart failure, gangrene, and end-stage renal disease were more likely to undergo endovascular repair. CONCLUSIONS: As more medically complex patients undergo endovascular revascularization, endovascular revascularization for diabetic patients is becoming associated with higher total cost despite similar length of stay, minor amputation, and major amputation rates. Further studies are needed to continuously evaluate the post-procedural outcomes and cost effectiveness of this trend.

RESUMO

OBJECTIVE: We describe the development and evolution of a surgical technique that uses the robotic da Vinci Surgical System (Intuitive Surgical, Inc, Sunnyvale, Calif) for the transaxillary approach to repair the disabling thoracic outlet syndrome (TOS). We report our patient outcomes associated with the use of this robotic technique. METHODS: We present a retrospective review and analysis of data collected from a 16-year experience of a single surgeon using a robotic surgical system and technique for TOS surgery. From the initial design of an endoscope attached to a microvideo camera in 1982 to the adoption of the monorobotic arm with integrated voice in 1998, the main objective of the transaxillary approach has always been to improve visualization of congenital cervical anomalies of the scalene muscles. From February 2003 to December 2018, we performed 412 transaxillary decompression procedures using the robotic da Vinci Surgical System. The surgical procedure has been described in further detail and includes the following steps: (1) positioning of the patient into a lateral decubitus position and using a monoarm retractor; (2) creation of a mini-incision in the axillary area and creation and maintenance of the subpectoral anatomic working space; (3) placement of endoscopic ports and engagement of the robotic instrumentation; (4) dissection of extrapleural and intrapleural soft tissue; (5) creation of the "floater" first rib; (6) excision of the cervical bands and first rib; and (7) placement of thoracostomy tubes for drainage and closure of the incisions. RESULTS: None of the patients died, and no patient experienced permanent neurovascular damage of the extremity. Of the 306 patients, 22 (5% of 441 operations) experienced complications. One patient developed postoperative scarring that required a redo operation with a robotic-assisted transaxillary approach. CONCLUSIONS: With its three-dimensional visual magnification of the anatomic area, the endoscopic robotic-assisted transaxillary approach offers safe and effective management of disabling TOS symptoms. The endoscope facilitates observation of the cervical bands and the mechanism (pathogenesis) of the neurovascular compression that causes TOS, thereby allowing complete excision of the first rib, cervical bands, and scalene muscle. We sought to develop and perfect this robotic approach. The present study was not intended to be a comparative study to nonrobotic TOS surgery.

RESUMO

BACKGROUND: There is currently little consensus on the role of thrombectomy compared with catheter-directed lysis (CDL) for acute, extensive, proximal deep vein thrombosis (DVT). We sought to determine whether any differences in outcomes exist between thrombectomy and CDL in terms of postoperative venous patency, pulmonary emboli (PE), and bleeding/hematoma. METHODS: In an institutional review board-approved retrospective cohort study, patients from a single academic medical center with confirmed lower extremity DVT were divided into thrombectomy and CDL cohorts. Demographic information, comorbidities and laboratory data, postoperative patency, postoperative bleeding, postoperative PE, popliteal hematoma, and recurrence of DVT were collected. Type I error level was set at 0.05. RESULTS: Eighty-seven patients were identified, 51.7% received CDL, and 48.3% underwent thrombectomy. Patient comorbidities and hypercoagulable states were not significantly different among the groups. The two techniques did not have significantly different postoperative patency (P = 0.472), bleeding (P = 0.598), PE (P = 0.868), popliteal hematoma (P = 0.331), or recurrence of DVT (P = 0.835). CONCLUSIONS: In selecting optimum treatment for acute, extensive, proximal DVT, our retrospective cohort study found no significant differences among treatment groups in safety, efficacy, recurrence, and progression to PE. We conclude that modality of treatment should be decided based on hospital resources, surgeon experience, and comfort with each technique, patient's physiologic status, and associated costs.

RESUMO

BACKGROUND: Postoperative mortality after open and endovascular repair of thoracic aortic dissection (AD) has been the focus of previous research. However, a little has been published on the far less common isolated abdominal aortic dissection (IAAD). The aim of our study was to identify risk factors associated with 30-day postoperative mortality in patients with IAAD. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) was queried for patients who underwent open or endovascular AD repair from January 2010 to December 2015. Information regarding patient demographics, comorbidities, preoperative laboratory values, procedure details, and postoperative complications were analyzed, and predictors of 30-day mortality were identified. Risk stratification by the type of aortic repair and surgery setting was performed, and patient characteristics associated with mortality in each setting were determined. We employed chi-squared test, Student's t-test, and Mann-Whitney U test for the univariate analysis, while the multivariate analysis was performed using a stepwise binary logistic regression test. RESULTS: There were 229 patients who met the specified criteria, 15 died within 30 days postoperatively, and 214 survived beyond the same period (mortality rate was 6.5%). Among preoperative factors, a history of chronic obstructive pulmonary disease (COPD), preoperative ventilator dependence, preoperative transfusion of ≥1 unit packed RBCs, emergent operation, and advanced American Society of Anesthesiologists (ASA) class were associated with increased risk of mortality. Postoperative complications associated with a higher risk of mortality were acute kidney injury, mechanical ventilation ≥48 hours, unplanned intubation, myocardial infarction, septic shock, and blood transfusion. On multivariate analysis, risk factors independently associated with increased risk of mortality were a history of COPD (adjusted odds ratio [AOR], 10.5; P = 0.013), postoperative acute renal failure (AOR, 12.8; P = 0.003) and septic shock (AOR, 15.3; P = 0.014). CONCLUSIONS: Multiple preoperative and postoperative factors are associated with a high risk of death after IAAD repair. A better control of COPD and prevention of postoperative acute renal failure and septic shock may result in better outcomes.

RESUMO

OBJECTIVE: Acute stroke due to tandem cervical internal carotid artery (ICA) and intracranial large-vessel occlusion (ILVO) has a high rate of morbidity and mortality. The most appropriate treatment strategy for the extracranial culprit lesion remains unclear. In this study, we report our institutional outcomes with two approaches: emergent carotid endarterectomy (CEA) and carotid artery stenting (CAS). METHODS: Patients with tandem ICA-ILVO were identified in a prospective mechanical thrombectomy (MT) database between July 2012 and April 2016. Patients had a concomitant complete ICA origin occlusion and occlusion of the intracranial ICA or M1 or M2 middle cerebral artery segment. Baseline characteristics, procedural data, and treatment times were reviewed. End points included good recanalization of both ICA and ILVO, symptomatic intracerebral hemorrhage (defined by clinical decline of >4 points on the National Institutes of Health Stroke Scale), and functional outcome at 90 days. RESULTS: Forty-five patients had tandem ICA-ILVO occlusion; 27 patients underwent emergent CAS and 12 patients underwent emergent CEA after MT. Successful Thrombolysis in Cerebral Infarction grade 2B/3 recanalization was achieved in 92% of the CEA and 96% of the CAS patients (P = .53). Three CAS patients (11%) and none of the CEA patients had symptomatic intracerebral hemorrhage (P = .54). At 90 days, 75% (9/12) of the CEA patients were functionally independent compared with 70% (19/27) in the CAS group (P = 1.0). No deaths were noted in the CEA group compared with five (18.5%) in the CAS arm (P = .30). CONCLUSIONS: Our study indicates that early recanalization with MT followed by emergent CEA is safe and feasible, which suggests that both CAS and CEA should be considered in the emergent treatment of patients with tandem occlusion.

RESUMO

Carotid artery stenting (CAS) has been adopted more in the treatment of carotid artery stenosis recently. The vast majority of studies about this procedure have concentrated mainly on the short- and long-term clinical complications, that is, stroke, myocardial infarction, and restenosis. However, mechanical complications including both stent fracture and carotid pseudoaneurysm are under-reported. In the present report, we present a patient with a common carotid artery psuedoaneurysm as a complication of CAS.

RESUMO

OBJECTIVE: To evaluate retrievable IVC filters in our institution and assess their retrieval following a well-structured follow up program. DESIGN: Retrospective cohort study. MATERIALS: The medical records of patients implanted with retrievable IVC filters were reviewed. METHODS: All retrievable filter insertions between July 2007 and August 2011 at our institution were reviewed. Data was analyzed for age, gender, indication, complications, retrieval rate, and brand of filter inserted. Statistical analysis was done using SPSS software v19. Chi-square was used to compare discrete data and t-test for continuous data. P < 0.05 was significant. RESULTS: A total of 484 patients were reviewed of which 258 (53.1%) had a complete medical record. And 96 (37.2%) filters were placed as permanent at the time of insertion. An additional 40 (15.5%) filters were converted to permanent (total permanent filters 136; 52.7%). Death was reported in 26 (10%) patients and 96 (37.2%) out of the remaining 232 patients presented for potential retrieval. Also, 73 (28.2%) had an attempt to retrieve the filters, 69 (94.5%) were successful and 4 (5.4%) failed to retrieve. The remaining 23 (8.9%) patients declined retrieval. Filters studied include Celect (38%), Bard (31.4%), Option (26.2%), Tulip (4.1%), and Recovery (0.2%). Bard was more commonly used as a retrievable filter (80.9%). Retrieval on the first attempt was 90.4% (n = 66) successful. Of the remaining seven filters, three were successfully retrieved on a second attempt, and four failed to retrieve due to filter tilt. The success rates of retrieval for Celect and Tulip were significantly lower than for Bard (p = 0.04 and 0.023, respectively). CONCLUSION: Our study showed that a variety of IVC filters can be retrieved successfully with minimal complication rates. In more than half of our patients, IVC filters were used as permanent.

RESUMO

STUDY OBJECTIVES: 1. Describe the prevalence of Meniere's disease in the United States. 2. Recognize important patient and environmental factors in Meniere's disease. METHODS: • Discharge data from the Nationwide Inpatient Sample, the largest US all-payer inpatient care database was analyzed for Meniere's disease between 2008 and 2010 in patients > 10 years old. Patient characteristics including prevalence, age, sex, race, household income, and geographic location were studied to determine any correlation with disease prevalence. • T-test, Chi-square and logistic regression testing was used to compare the differences between groups for continuous and categorical data. RESULTS: • The lower limit of Meniere's prevalence in the United States population was 73 per 100,000, females 84 per 100,000 compared to 56 per 100,000 among males (OR = 1.51, 95% CI 1.48-1.54, P < 0.01). • Prevalence was highest in Caucasians 91 per 100,000, and was significantly higher than other ethnic groups (P < 0.05). • Prevalence increased as age with the highest prevalence found in 81-90 year age group. • Midwest prevalence (94 per 100,000) was significantly higher than other regions (P < 0.001). • Meniere's is more common in less populated locations and the prevalence decreased as population increased. • Meniere's prevalence increased with household income. The highest prevalence was found among the 76th-100th quartile with rates of 86 per 100,000 for MD. CONCLUSIONS: Environmental factors, race and ethnicity, gender and age appear to be important factors in the prevalence of Meniere's disease.

RESUMO

BACKGROUND: This case report presents the challenges associated with the existing screening modalities in the diagnosis of carotid artery dissection, and also reviews the diagnostic efficiency, limitations, and recent advances in imaging technology. CASE PRESENTATION: A 54-year-old man with blunt trauma and subsequent development of ischemic stroke and no clear initial evidence of carotid dissection with noninvasive screening, including magnetic resonance imaging, magnetic resonance angiography, and computed tomography angiography. CONCLUSIONS: Despite emerging noninvasive imaging techniques, conventional angiography should still be considered to establish a diagnosis of carotid artery dissection, particularly when other imaging modalities are negative or inconclusive but a high degree of clinical suspicion exists based on symptoms or mechanism of injury.

RESUMO

Persistent sciatic artery (PSA) is an uncommon medical condition that can result in limb loss if it is not recognized or corrected. It is associated with 14% limb loss and 86% formation of aneurysm of the sciatic artery. In this study we describe a patient with bilateral persistent sciatic arteries associated with multiple aneurysms who presented with a large aneurysm formation and limb ischemia. The patient was treated with PSA embolization and exclusion of the aneurysm in the right leg with vein bypass. All reported cases in the English literature between 1965 and 2012 were reviewed and management options were compared.

RESUMO

BACKGROUND: Venous thromboembolism (VTE) stands as the leading cause of preventable death within hospitals in the United States. Although there have been some studies investigating the incidence rates of VTE, there has yet to be a large-scale study elucidating disparities in sex, race, income, region, and seasons in patients with VTE. The goal of this study was to report the disparities in race, sex, income, region, and seasons in patients with VTE, pulmonary embolism (PE), and deep vein thrombosis (DVT), in hospitalized patients from 2016 to 2019. METHODS: We used the United States National Inpatients Sample database to identify inpatients diagnosed with PE, DVT, and PE and DVT from 2016 to 2019. The inpatient incidence per thousand was calculated for sex and race using the weighted sample model. The regional and monthly incidence of DVT and PE per thousand inpatients and risk of incidence were calculated. Patients' characteristics including hospital type, bed size, median length of stay, median total charges, and mortality were also collected. RESULTS: We examined 455,111 cases of VTE, 177,410 cases of DVT, 189,271 cases of PE, and 88,430 cases of both DVT and PE combined. Over the study period, we observed a statistically significant trend among PE hospitalization incidences. There was a strong and positive correlation between DVT and PE inpatients. Black inpatients had the highest cumulative incidence of hospitalizations in all cohorts with 10.36 per 1000 in PE and 9.1 per 1000 in DVT. Asian and Pacific Islander inpatients had the lowest cumulative incidence with 4.42 per 1000 in PE and 4.28 per 1000 in DVT. Females showed the lowest cumulative incidence with 7.47 per 1000 in PE and 6.53 per 1000 in DVT. The Mountain region was the highest among PE hospitalizations with 9.62 per 1000. For DVT, the Middle Atlantic region was the highest at 8.65 per 1000. The in-hospital mortality rate was the highest among the PE hospitalizations at 7.3%. Also, the trend analysis showed significant increases among all groups. CONCLUSIONS: Over the study period (2016-2019), we report the racial, biological sex, and geographical disparities from the National Inpatient Sample database, highlighting that Black inpatients had the highest incidence of PE and DVT, whereas Asian/Pacific Islander inpatients had the lowest incidences of PE and DVT. Moreover, women had a lower incidence compared with men. The observed regional variations indicated that the incidence of PE was highest in the Mountain region, whereas the incidence of DVT was lowest in the Middle Atlantic region. There was an increase in the mortality of inpatients diagnosed with VTE reflecting the growing burden of this condition in the US health care system.

RESUMO

OBJECTIVES: Patients with peripheral artery disease (PAD) often require treatment with open lower extremity revascularization (LER). Patients with PAD often have other comorbidities and associated conditions that affect procedural outcomes, including abdominal stomas. The aim of this work is to investigate the impact that stomas may have on postoperative outcomes and complications. METHODS: We performed a 5-year (2016-2020) analysis of the Nationwide Readmission Database. We identified all adult patients undergoing open LER. These patients were categorized into 2 groups: stoma and no-stoma. Propensity score matching (1:1) was used to control for demographics and comorbidities. Index admission outcomes and readmission rate were examined. RESULTS: 212,275 open LER patients were identified. A matched cohort of 3088 patients (1:1 stoma vs no-stoma) was obtained. Patients with stomas had higher rates of several postoperative complications: acute posthemorrhagic anemia (29.1%, P < 0.01), acute kidney injury (21.4%, P < 0.001), index sepsis (10.3%, P < 0.001), and index SSI (2.8%, P < 0.001). There were no significant statistical differences between the 2 groups for acute myocardial infarction. Those with stomas had worse outcomes: greater in-hospital mortality (4.7%, P < 0.05), length of stays (median 7 days, P < 0.001), total charges (median 108,037 dollars, P < 0.001), discharges to long-term care facilities (30.8%, P < 0.001), discharges to their own homes needing home health care (30.1%, P < 0.001), 30-day readmission rates (23.2%, P < 0.01), and 30-day readmission mortality (6.1%, P < 0.01). CONCLUSIONS: Concurrent abdominal stoma is associated with increased postoperative morbidity and mortality after open LER. Further prospective studies are needed to validate these results.

RESUMO

OBJECTIVES: Studies have shown that coronavirus disease 2019 (COVID-19) is associated with a hypercoagulable state. Studies have yet to examine the interconnectedness between COVID-19, hypercoagulability, and socioeconomics. The aim of this work was to investigate socioeconomic factors that may be associated with pulmonary embolism (PE), deep vein thrombosis (DVT), and COVID-19 in the United States. METHODS: We performed a 1-year (2020) analysis of the National Inpatient Sample database. We identified all adult patients diagnosed with COVID-19, acute PE, or acute DVT using unweighted samples. We calculated the correlation and odds ratio (OR) between COVID-19 and (1) PE and (2) DVT. We executed a univariate analysis followed by a multivariate analysis to examine the effect of different factors on PE and DVT during the COVID-19 pandemic. RESULTS: We identified 322,319 patients with COVID-19; 78,101 and 67,826 patients were identified with PE and DVT, respectively. PE and DVT, as well as inpatient mortality associated with both conditions, are significantly correlated with COVID-19. The OR between COVID-19 and PE was 2.04, while the OR between COVID-19 and DVT was 1.44. Using multivariate analysis, COVID-19 was associated with a higher incidence of PE (coefficient, 2.05) and DVT (coefficient, 1.42). Other factors that were significantly associated (P < .001) with increased incidence of PE and DVT along with their coefficients, respectively, include Black race (95% confidence interval [CI], 1.23-1.14), top quartile income (95% CI, 1.08-1.16), west region (95% CI, 1.10-1.04), urban teaching facilities (95% CI, 1.09-1.63), large bed size hospitals (95% CI, 1.08-1.29), insufficient insurance (95% CI, 1.88-2.19), hypertension (95% CI, 1.24-1.32), and obesity (95% CI, 1.41-1.25). Factors that were significantly associated (P < .001) with decreased incidence of PE and DVT along with their coefficients, respectively, include Asians/Pacific Islanders (95% CI, 0.52-0.53), female sex (95% CI, 0.79-0.74), homelessness (95% CI, 0.62-0.61), and diabetes mellitus (0.77-0.90). CONCLUSIONS: In the Nationwide Inpatient Sample, COVID-19 is correlated positively with venous thromboembolism, including its subtypes, PE and DVT. Using a multivariate analysis, Black race, male sex, top quartile income, west region, urban teaching facilities, large bed size hospitals, and insufficient social insurance were associated significantly with an increased incidence of PE and DVT. Asians/Pacific Islanders, female sex, homelessness, and diabetes mellitus were significantly associated decreased incidence of PE and DVT.

RESUMO

Laparoscopic sleeve gastrectomy (LSG) is the most frequently performed bariatric procedure. To study the safety of LSG done with Nissen Fundoplication (NF) in patients affected by obesity and GERD and assess the complication rate. A retrospective cohort study using the Nationwide Readmissions Database from 2016 to 2019. A total of 236111 patients underwent LSG with and without NF. A matched cohort of 1096 without NF and 548 with NF was obtained. The median age of patients was 47 years old. Median length of hospital stay was higher in the LSG with NF group. Median total charge was higher in the LSG with NF group. There was no statistically significant difference in 30-day readmission rates in patients with obesity and GERD who received LSG with NF compared to those who received LSG alone. Complications after both procedures were low, which highlights the safety of both procedures.

RESUMO

BACKGROUND: Peritoneal dialysis is a popular option for patients with end-stage renal disease. A recent presidential executive order has incentivized in-home end-stage renal disease treatments, leading to an increase in peritoneal dialysis use. Guidelines exist for creating and maintaining peritoneal dialysis access without addressing the optimal technique. This study evaluates nationwide peritoneal dialysis catheter placement practices and their long-term outcomes. METHODS: Retrospective cohort analysis of Nationwide Readmission Database from 2017 to 2019. Patients with end-stage renal disease undergoing inpatient peritoneal dialysis catheter placement were included. Six-month readmissions, mortality, and peritoneal dialysis catheter-specific outcome measures were assessed among survivors of admission, including catheter leakage, mechanical breakdown, displacement, revision or replacement, removal, exit site infections, intra-abdominal abscess, and sepsis. Binary logistic regression analyses were performed. RESULTS: In the study, 14,863 patients with inpatient peritoneal dialysis catheter insertions were identified, of which 7,096 were analyzed (4,150 [59%] laparoscopic, 1,781 [25%] fluoroscopic, 1,165 [16%] open), 847 (12%) had major complications, 931 (13%) were readmitted, and 102 (1.4%) died within 6 months. Univariate analyses demonstrated that laparoscopy had higher mechanical complications, exit-site infections, catheter revision, and removal within 6 months, and fluoroscopy had higher sepsis and mortality. Multivariate analyses showed fluoroscopy was associated with intraabdominal abscess (adjusted odds ratio, 2.36; P = .025), laparoscopy with exit-site infections (adjusted odds ratio, 0.49; P = .005), and open surgery with catheter displacement (adjust odds ratio, 2.95; P = .021). CONCLUSION: This is the first large-scale study on inpatient peritoneal dialysis catheter placement outcomes in the United States. Fluoroscopic and open surgical placements are routinely performed, but laparoscopy remains the mainstay with fewer exit-site infections. Overall, peritoneal dialysis is a safe option, with 1 in 9 patients having an infectious or mechanical complication within 6 months. Furthermore, large-scale prospective studies are warranted to identify the optimal placement technique.
