Effect of preoperative heart failure on arteriovenous access patency and prognosis in patients on hemodialysis.

Background: The risk of arteriovenous (AV) access failure is associated with hemodynamic factors, clinical factors, or technical issues. Although several studies have shown the detrimental effects of AV access on heart function, few studies have assessed whether heart function affects AV access patency. We investigated the impact of cardiac function on AV access patency.

Endovascular Treatment versus Open Surgical Repair for Isolated Iliac Artery Aneurysms.

Purpose: Endovascular treatment (EVT) has been shown to be effective and safe for isolated iliac artery aneurysms (IAAs). However, concerns remain regarding the lack of consideration to recent advances in perioperative care and surgical techniques, as well as a significant number of re-interventions with EVT. This study compares the outcomes of open surgical repair (OSR) and EVT using recent clinical data.

Management strategy for extracranial carotid artery aneurysms: A single-center experience.

Abstract: This single-center, retrospective study aimed to describe the anatomic and clinical characteristics of extracranial carotid artery aneurysms (ECAAs) and to compare various ECAA management strategies in terms of outcomes.A total of 41 consecutive patients, who underwent treatment for ECAAs between November 1996 and May 2020, were included in this study. The ECAAs were anatomically categorized using the Attigah and Peking Union Medical College Hospital (PUMCH) classifications.

Aortoiliac diameter and length in a healthy cohort.

Objective: Diameter is currently the only screening and diagnostic criterion for asymptomatic aneurysms. Therefore, aortic and lower-extremity arterial diameter has diagnostic, therapeutic, and prognostic importance. We aimed to determine aortic and lower-extremity arterial reference diameters in a general population and compare them according to age, sex, and other characteristics.

Long-term outcomes of large artery thromboangiitis obliterans and comparison with small artery thromboangiitis obliterans.

Although the distribution of arterial involvement is still the subject of controversy for defining the diagnostic criteria for thromboangiitis obliterans (TAO), several reports have described TAO involving the more proximal arterial segment. This study aimed to investigate the clinical characteristics and outcomes of large artery TAO in comparison with those of small artery TAO.Between January 2007 and July 2019, 83 consecutive symptomatic patients with a diagnosis of lower extremity TAO were stratified according to the most proximal arterial involvement, with the cutoff level of the adductor canal as a reference (large artery TAO versus small artery TAO), and analyzed retrospectively.

Impact of Chronic Kidney Disease Under Nephrology Care on Outcomes of Carotid Endarterectomy.

Objective: This study aimed to investigate the impact of chronic kidney disease (CKD) and the delivery of nephrology care on outcomes of carotid endarterectomy (CEA).

Methods: This was a single centre, retrospective observational study. Between January 2007 and December 2014, 675 CEAs performed on 613 patients were stratified by pre-operative estimated glomerular filtration rate (eGFR) values (CKD [eGFR < 60 mL/min/1.

Risk Factors for Early and Late Type Ib Endoleak Following Endovascular Abdominal Aortic Aneurysm Repair.

Objectives: A type Ib endoleak (T1bEL) is a postoperative complication that usually requires additional interventions following endovascular aortic aneurysm repair. Previous studies have focused on iliac artery tortuosity or common iliac artery (CIA) diameter. However, we investigated the various risk factors for early and late T1bELs more comprehensively.

Risk Factors for Early and Late Iliac Limb Occlusions of Stent Grafts Extending to the External Iliac Artery after Endovascular Abdominal Aneurysm Repair.

Background: Iliac limb stent grafting to the external iliac artery (EIA) is a commonly performed procedure in various situation during endovascular abdominal aneurysm repair (EVAR). However, this procedure is associated with a risk of graft occlusion. We evaluated risk factors affecting occlusion among patients who underwent iliac limb stent-graft extension to the EIA.

Risk Factors of Bacteremia following Multiple Traumas.

Background: Bacteremia is a major nosocomial infection that frequently occurs in trauma patients, increasing morbidity and mortality. The aim of this study was to identify risk factors and to describe epidemiological patterns for early onset (EOB) and late onset (LOB) bacteremia after trauma.

Methods: We retrospectively reviewed medical records of all trauma patients admitted to the surgical intensive care unit and general ward between January 2011 and December 2015.

Fate of Pure Type II Endoleaks Following Endovascular Aneurysm Repair.

Purpose: Type II endoleaks (T2ELs) are the most common type of endoleaks observed after endovascular aneurysm repair (EVAR). However, whether T2ELs should be treated remains debatable. In the present study, we aimed to describe the natural course of T2ELs and suggest the direction of their management.
