OBJECTIVES: Studies have demonstrated socioeconomic status, insurance, race, and distance impact clinical outcomes in patients with abdominal aortic aneurysms (AAA). The purpose of this study was to assess if these factors also impact clinical outcomes in patients with thoracoabdominal aortic aneurysms (TAAA). METHODS: We conducted a retrospective review of patients with TAAAs confirmed by CT imaging between 2009 to 2019 at a single institution. Patients' zip codes were mapped to American Community Survey Data to obtain geographic poverty rates...

OBJECTIVE: Comorbid chronic kidney disease (CKD) is associated with worse outcomes for patients with chronic limb-threatening ischemia (CLTI). However, comparative effectiveness data is limited for lower extremity bypass (LEB) vs. peripheral vascular intervention (PVI) in patients with CLTI and CKD. We aimed to evaluate 1) 30-day all-cause mortality and amputation and 2) 5-year all-cause mortality and amputation for LEB vs. PVI in patients with comorbid CKD. METHODS: Individuals undergoing LEB and PVI were queried from the Vascular Quality Initiative with Medicare claims-linked outcomes data...

OBJECTIVES: Society for Vascular Surgery guidelines recommend revascularization for patients with intermittent claudication (IC) if it can improve patient function and quality of life. However, it is still unclear if IC patients achieve a significant functional benefit from surgery compared to medical management alone. This study examines the relationship between IC treatment modality (operative vs. non-operative optimal medical management) and patient reported outcomes for physical function (PROMIS-PF) and satisfaction in social roles and activities (PROMIS-SA)...

OBJECTIVES: To evaluate the 5-year outcomes of fenestrated/branched endovascular aortic repair (F/BEVAR) for the treatment of complex aortic aneurysms stratified by the aneurysm extent. METHODS: Patients with the diagnosis of complex aortic aneurysm, who underwent F/BEVAR at a single center were included in this study and retrospectively analyzed. The cohort was divided according to the aneurysm extent, comparing group 1 (types I-III thoracoabdominal aneurysms-TAAA), group 2 (type IV TAAA), and group 3 (juxtarenal, pararenal, or paravisceral aortic aneurysms - JRAA, PRAA, PVAA)...

OBJECTIVE: Indirect revascularization is a common and effective treatment for pediatric moyamoya disease. However, in several cases postoperative angiogenesis is not sufficient. It is not fully understood which factors are involved in the development of postoperative collateral circulation. In this study, the authors aimed to elucidate the factors related to postoperative angiogenesis in indirect revascularization. METHODS: Among the patients who underwent indirect revascularization for moyamoya disease from January 2015 to December 2022, those whose angiogenesis was evaluated using angiography were included...

OBJECTIVE: Vascular injuries in anterior lumbar interbody fusion (ALIF) occur due to the vascular manipulation needed to achieve optimal disc space exposure. In this study, the authors aimed to evaluate intraoperative vascular injuries in patients undergoing single- and multilevel ALIF at a large tertiary academic center. METHODS: Prospectively collected data specifically addressing postoperative complications in patients who underwent ALIF by neurosurgery spine faculty working with a specialized vascular surgeon were retrospectively reviewed...

OBJECTIVE: Chiari malformation type I (CM-I) is a congenital disorder occurring in 0.1% of the population. In symptomatic cases, surgery with posterior fossa decompression (PFD) is the treatment of choice. Surgery is, however, associated with peri- and postoperative complications that may require readmission or renewed surgical intervention. Given the associated financial costs and the impact on patients' well-being, there is a need for predictive tools that can assess the likelihood of such adverse events...

RATIONALE: Due to the lack of specificity symptoms and site of onset of castleman disease (CD), it is difficult to diagnose and poses unique challenges for both patients and clinicians, leading to confusion in diagnosis and delays in treatment. To enhance understanding, we present 3 cases of CD treated at our hospital, including a single-center, multicenter, and mixed-type CD. PATIENT CONCERNS: Case 1: A 53-year-old female patient was admitted with a chief complaint of "abdominal pain and fever for 10 days...

OBJECTIVE: The objective of this study was to investigate the flow effects in different degrees of thoracic aortic stent graft protrusion extension by creating bird beak effect simulations using accurate 3D geometry and a realistic, nonlinear, elastic biomechanical model using computer-aided software SolidWorks. METHODS: Segmentation in 3D of an aortic arch from a computed tomography (CT) scan of a real-life patient was performed using SolidWorks. A parametric analysis of three models was performed: (A) Aortic arch with no stent, (B) 3 mm bird-beak configuration, and (C) 6...

Situs inversus totalis is a rare congenital malformation in which organs are positioned in a mirror-image relationship to normal conditions. It often presents with vascular and biliary malformations. Only a few reports have pointed out the surgical difficulties in patients with situs inversus totalis, especially in those with perihilar cholangiocarcinoma. This report describes a 66-year-old male patient who underwent left hemihepatectomy (S5, 6, 7, and 8) with combined resection of the caudate lobe (S1), extrahepatic bile duct, and regional lymph nodes for perihilar cholangiocarcinoma with situs inversus totalis...

PURPOSE: Pancreatic ductal adenocarcinoma (PADC) still has nowadays a very impaired long-term survival. Most studies are focused on overall survival; however, local recurrence occurs about up to 50% of cases and seems to be highly related with margin resection status. We aim to analyze the impact of vascular resection margins on local recurrence (LR) and to assess its impact on overall and disease-free survival. METHODS: Eighty out of 191 patients who underwent pancreatoduodenectomy in a university hospital between 2006 and 2021 with PDAC diagnosis were analyzed and vascular margin status specifically addressed...

BACKGROUND: Vascular surgical site infections have been reported with an overall incidence of 5-10% for patients undergoing arterial interventions and as high as 10-20% for lower-limb bypass grafting procedures. Given that vascular surgery patients are known to be at a higher risk of postoperative wound infections and other complications, our objective was to evaluate a potential method to reduce such complications. This study compares the rate of wound healing complications between incisional negative pressure wound therapy (NPWT) and conventional dressings in vascular surgery patients with infra-inguinal incisions...

OBJECTIVE: To explore whether there is an association between serious mental illness (SMI) and hearing loss (HL) among US Hispanic adults. STUDY DESIGN AND SETTING: Cross-sectional epidemiological study (Hispanic Community Health Study), including multicentered US volunteers. METHODS: Multivariable linear regressions were conducted to study the association between SMI and HL. Adjustments were made for potential confounders including age, sex, education, vascular disease (hypertension or diabetes mellitus), and cognition...

BACKGROUND: Malignant atrophic papulosis (MAP) is a rare obliterative vasculopathy whose etiology and pathophysiological mechanisms remain unknown, and the treatment is still empirical. It can involve multiple systems, especially the gastrointestinal tract and central nervous system, and has a poor prognosis. CASE PRESENTATION: A 20-year-old Chinese male appeared to have Widespread atrophic papules and plaques, intermittent abdominal pain, recurrent bowel perforation, and psoas abscess...

AIM: To report the clinical outcomes of thoracoscopic left atrial appendage occlusion (LAAO) with the AtriClip PRO2 device (Atricure Inc, Mason, OH, USA). Stroke risk reduction with LAAO in patients with atrial fibrillation is now well-established. Many surgical and percutaneous techniques have been used, with varying rates of success. The percutaneous devices have had issues with procedural complications and peridevice flow. Thoracoscopic AtriClip offers an epicardial linear closure of the appendage at its ostium...

Cerebrovascular surgery has many intraoperative imaging modalities available. Modern technologies include intraoperative digital subtraction angiogram, indocyanine green (ICG) angiography, relative fluorescent measurement with ICG, and ultrasound. Each of these can be used effectively in the treatment of open aneurysm and arteriovenous malformation surgeries, in addition to arteriovenous fistula surgery, and cerebral bypass surgery.

Multidisciplinary teams are necessary to treat complex patients with Chronic Limb Threatening Ischemia (CLTI). The need for adequate wound care and control of comorbid conditions cannot be accomplished by the vascular specialist alone. Numerous specialties have a role in this group to include surgical podiatrists, orthopedic surgery, plastic and reconstructive surgery endocrinology, and wound care. However, the vascular specialist must drive this team as the patients are usually referred to them and numerous studies have shown a direct correlation between major amputations and the lack of vascular involvement...

BACKGROUND: Endovascular treatment (EVT) for aortoiliac (AI) occlusive lesions is now conducted worldwide, but there are challenges in EVT for complex AI lesions. The VIABAHN VBX (W.L. Gore & Associates, Flagstaff, AZ) is a next-generation balloon-expandable covered stent designed for use with complex AI lesions. The purpose of this study is to evaluate the medium-term outcomes of VIABAHN VBX for such lesions. METHODS: Symptomatic patients who underwent EVT with VIABAHN VBX for an AI lesion from 2018 to 2020 at 7 Japanese centers were reviewed retrospectively...

OBJECTIVES: The primary treatment for lower extremity peripheral arterial occlusive disease (PAOD) is angioplasty-stenting. Its main complication is in-stent restenosis. Poor selection of stent dimensions has been identified as a factor contributing to early in-stent restenosis. The aim of this study is to determine whether the implantation of stents, selected based on arterial morphological reconstruction using sizing software, reduces the occurrence of in-stent restenosis. The study also aims to evaluate the potential benefits of routine preoperative sizing...
