Background: The treatment outcomes of vein and bovine pericardial patches in thromboendarterectomy (TEA) for common femoral artery (CFA) lesions in patients with peripheral arterial disease (PAD) remain unclear. The purpose of this study was to evaluate the efficacy and safety of the bovine pericardial patch by comparing it with vein patch angioplasty.
Methods: This was a multicenter retrospective study.
Background: To examine the influence of liver function on patients with chronic limb-threatening ischemia (CLTI), we classified patients with CLTI after revascularization according to their modified albumin-bilirubin (ALBI) grades.
Methods: We retrospectively analyzed single-center data of patients who underwent revascularization for CLTI between 2015 and 2020. Patients were classified with ALBI grades 1, 2a, and 2b and 3 according to the ALBI score, which was calculated, based on serum albumin and total bilirubin levels.
Background: This study aimed to analyze the clinical outcomes after revascularization for chronic limb-threatening ischemia (CLTI) in patients aged ≥ 80 years and < 80 years.
Methods: We retrospectively analyzed multicenter data of 789 patients who underwent infrainguinal revascularization for CLTI between 2015 and 2021. The end points were 2-year overall survival (OS), amputation-free survival (AFS), limb salvage (LS), and postoperative complications.
Objective: This study aimed to evaluate treatment outcomes after bypass surgery or endovascular therapy (EVT) in average- and high-risk patients with chronic limb-threatening ischemia (CLTI).
Methods: We retrospectively analyzed multicenter data of patients who underwent infra-inguinal revascularization for CLTI between 2015 and 2022. A high-risk patient was defined as one with estimated 30-day mortality rate ≥5% or 2-year survival rate ≤50%, as determined by the Surgical Reconstruction vs Peripheral Intervention in Patients With Critical Limb Ischemia (SPINACH) calculator.
Background: Postoperative lymphatic leakage is a complication of ineffective conservative treatment for retroperitoneal mass. Herein, we report a case of lymphatic leakage that arose after retroperitoneal tumor resection and that was treated with retrograde transvenous thoracic duct embolization.
Case Presentation: A 28-year-old man with persistent abdominal pain was diagnosed with a large retroperitoneal metastatic tumor measuring 10 cm and a subdiaphragmatic lymph node originating from a testicular tumor.
Objective: This study aimed to evaluate three survival prediction models: the JAPAN Critical Limb Ischaemia Database (JCLIMB), Surgical Reconstruction Versus Peripheral Intervention in Patients With Critical Limb Ischaemia (SPINACH), and Vascular Quality Initiative (VQI) calculators.
Methods: Multicentre data of patients who underwent infrainguinal revascularisation for chronic limb threatening ischaemia between 2018 and 2021 were analysed retrospectively. The prediction models were validated using a calibration plot analysis with the intercept and slope.
Objective: To examine limb salvage (LS) and wound healing in dialysis-dependent and -independent patients with chronic limb-threatening ischemia (CLTI) after infrainguinal bypass surgery or endovascular therapy (EVT).
Methods: We retrospectively analyzed the multi-center data of patients who underwent infrainguinal revascularization for CLTI with Wound, Ischemia, and foot Infection (WIfI) stage 2 to 4 between 2015 and 2020. The primary endpoint was LS.
Background: The present study aimed to determine the preferred initial revascularization procedure between bypass surgery and endovascular therapy (EVT) in patients with chronic limb-threatening ischemia (CLTI) categorized as indeterminate according to the Global Vascular Guidelines (GVG).
Methods: We retrospectively analyzed the multicenter data of patients who underwent infrainguinal revascularization for CLTI categorized as indeterminate according to the GVG between 2015 and 2020. The end point was the composite of relief from rest pain, wound healing, major amputation, reintervention, or death.
Background: Left renal vein division (LRVD) is a maneuver performed during open surgical repair for abdominal aortic aneurysms. Even so, the long-term effects of LRVD on renal remodeling are unknown. Therefore, we hypothesized that interrupting the venous return of the left renal vein might cause renal congestion and fibrotic remodeling of the left kidney.

Methods: We retrospectively analyzed data from two vascular centers for patients who underwent revascularization for CLTI between 2015 and 2020. The primary endpoint was overall survival (OS), and the secondary endpoints were changes in ambulatory status and postoperative complications.
Background: To evaluate limb salvage outcomes and risk factors for major amputation in chronic limb-threatening ischemia (CLTI) patients classified as stage 4 per the wound, ischemia, and foot infection (WIfI) classification following infrainguinal revascularization.
Methods: We retrospectively analyzed multicenter data of patients who had undergone infrainguinal revascularization for CLTI between 2015 and 2020. The endpoint was secondary major amputation defined as an above- or below-knee amputation following infrainguinal revascularization.
Objective: Postoperative limb infection is associated with a poor prognosis and a low amputation-free survival rate after surgical revascularization in patients with critical limb-threatening ischemia. The Global Vascular Guidelines 2019 recommend antibiotic therapy for patients with deep space foot infection or wet gangrene; however, no study is cited as evidence for this recommendation. The present study was performed to offer new evidence supporting the use of perioperative therapeutic antibiotics in patients with critical limb-threatening ischemia (CLTI) undergoing surgical revascularization.

Interleukin-38 (IL-38) is a member of the IL-1 family, which binds to IL-36 receptor (IL1RL2) and has an anti-inflammation effect. Because macrophages express IL1RL2, we hypothesized that IL-38 suppresses AAA formation by controlling macrophages.

The relationship between abdominal aortic aneurysm and the gut microbiota remains unknown. This study aimed to detect bacterial translocation in the aneurysmal wall and blood of patients with abdominal aortic aneurysm, and to investigate the effect of the gut microbiota on abdominal aortic aneurysm.

The endpoints were major amputation, major adverse limb events (MALE), and wound healing.
Results: Overall, 276 patients and 340 limbs were analysed.
Objective: Ureteroarterial fistula (UAF) is lethal condition. However, no consensus has been reached regarding the diagnosis and treatment of UAF owing to its rarity. The aim of our report was to present an actual case of UAF and systematically review the symptoms, risk factors, diagnosis, and treatment of this condition.

Method: We retrospectively analyzed data of patients who underwent revascularization for CLTI between 2008 and 2020. The endpoints were 2-year overall survival and limb salvage.
We report a case of an 83-year-old man with a ruptured internal iliac artery (IIA) aneurysm after endovascular repair, which was treated via the ligation of IIA and tight suture of the aneurysm sac. Although there were no findings of obvious endoleak after endovascular treatment, the IIA aneurysm increased in size and eventually ruptured. We presumed that pressure to IIA aneurysm via the embolized IIA led to rupture.

Methods: In the present study, we retrospectively analyzed data from 268 patients with fusiform aneurysm and sac behavior who had been evaluated for ≥1 year after EVAR. Hostile neck anatomy was defined as a proximal aneurysmal neck length of <10 mm or proximal neck angle of ≥60°.

Objective: The present study aimed to determine the factors related to relief from rest pain, wound healing, major adverse limb events (MALEs), and prognosis after infrainguinal revascularisation in patients with chronic limb threatening ischaemia (CLTI).
Methods: The data of patients who underwent infrainguinal revascularisation for CLTI between 2010 and 2020 was analysed retrospectively. The endpoint was the composite of relief from rest pain, wound healing, MALE, or death.
Background: Iliac artery aneurysms (IAAs) are life-threatening once ruptured. Although some studies have revealed the pathology of IAAs, clinical information on IAAs is still limited. Moreover, previous studies were conducted in Western countries; thus, we aimed to identify the natural history of iliac artery aneurysms in a Japanese cohort.
