Importance: In a recent meta-analysis of randomized clinical trials, femoropopliteal artery revascularization with paclitaxel drug-coated devices was associated with increased long-term all-cause mortality compared with non-drug-coated devices. However, to our knowledge, these findings have not been replicated in other data sources and may be subject to confounding from missing data associated with patient withdrawal and loss to follow-up. Objective: To evaluate differences in all-cause mortality between patients who were treated with drug-coated devices vs non-drug-coated devices for femoropopliteal artery revascularization...

Background: Acute iliac arterial thrombosis during surgery is very rare complication. There were few reports on this complication relative to gastroenterological surgery, and the risk has not been recognized. Case presentation: A 70-year-old man, diagnosed with a rectal cancer (adenocarcinoma of rectum) with known history heavy cigarette smoking with no known history of peripheral vascular disease underwent a laparoscopic abdominoperineal resection. He presented severe pain in the left leg in the recovery room...

Coronary artery disease (CAD) is a leading cause of death worldwide, and percutaneous transluminal coronary angiography (PTCA) and/or percutaneous coronary intervention (PCI; angioplasty) are commonly used to diagnose and/or treat the obstructed coronaries. Exercise-based rehabilitation is recommended for all CAD patients; however, most guidelines do not specify when exercise training should commence following PTCA and/or PCI. Catheterization can result in arterial dysfunction and acute injury, and given the fact that exercise, particularly at higher intensities, is associated with elevated inflammatory and oxidative stress, endothelial dysfunction and a pro-thrombotic milieu, performing exercise post-PTCA/PCI may transiently elevate the risk of cardiac events...

Background: Percutaneous interventions help patients with various cardiovascular diseases, however radiation exposure is a safety concern for both patients and health care providers. We previously reported that dose area product (DAP) is apparently different in central body and upper-limb areas during percutaneous transluminal angioplasty for arteriovenous shunt dysfunction. In this study, we investigated the precise radiation dose at the patients' back and at the non-targeted organs of the operators...

BACKGROUND: Although several studies have evaluated the change of cognitive performance after severe carotid artery stenosis (CAS), the results still remain elusive. The objective of this study was to assess changes in cognitive function, depressive symptoms and health-related quality of life (HRQoL) after CAS revascularisation and best medical treatment (BMT). METHODS: Study involved 213 patients with severe (≥70%) CAS who underwent assessment of cognitive function using Montreal Cognitive Assessment scale (MoCA), depressive symptoms - using Patient Health Questionnaire-9 (PHQ-9) and HRQoL - using Medical Outcome Survey Short Form version 2 (SF-36v2)...

BACKGROUND: Five years of prospective clinical trials confirm that paclitaxel drug-coated balloons (DCB) is safe and effective to treat femoropopliteal artery disease. A recent meta-analysis of heterogenous trials of paclitaxel-based balloons and stents reported they are associated with increased mortality and higher doses are linked to higher mortality from 2-5 years. OBJECTIVES: Determine if there is a correlation between paclitaxel exposure and mortality by conducting an independent patient-level meta-analysis of 1,980 patients with up to 5-year follow-up...

BACKGROUND: As patient care is increasingly transitioned out of the hospital and into the outpatient setting, there is growing interest in developing office-based angiography suites, i.e. office-based labs. Office-based care has been associated with increased efficiency and greater patient satisfaction, with substantially higher reimbursement directly to the physicians providing care. Prior studies have demonstrated a shift of revascularization procedures to office-based labs with a concomitant increase in atherectomy use, a procedure with disproportionately high reimbursement in comparison to other peripheral revascularization techniques...

The distal forearm is the preferred site for hemodialysis access. However, forearm vessels have small diameter, which may lead to complications of arteriovenous fistulas constructed at this site. Indeed, the mean patency rate of such fistulas has been reported at 65.2% (range, 56-79%) at 1 year postoperatively. In this study, we aimed to evaluate the patency rate of Brescia-Cimino arteriovenous fistulas constructed under microscopic guidance. We retrospectively evaluated the records of patients with chronic renal failure who received a Brescia-Cimino arteriovenous fistula between 2014 and 2015 for hemodialysis access...

BACKGROUND: Xerosis, defined as abnormal skin dryness and scaling, is a common disorder in patients with diabetes. The skin may crack and develop fissures, potentially allowing bacterial entry and increasing vulnerability to ulceration and infection. Therefore, maintaining adequate skin hydration may be crucial for diabetic wound healing. However, no clinical study has addressed this issue. This study aimed to determine and compare the effect of the skin hydration level on diabetic wound healing with that of the tissue oxygenation level, which is recognized as the most reliable parameter in predicting diabetic wound healing...

BACKGROUND: Intracranial arterial stenosis (ICAS) is an important cause of ischemic stroke worldwide due to its higher risk of recurrence with medical therapy. Although some large randomized studies failed to show the superiority of surgical treatment compared with medical therapy, the results of medical therapy are not sufficient. There are patients who still benefit from surgical treatment. This retrospective analysis aimed to evaluate the long-term efficacy of surgical therapy with percutaneous transluminal angioplasty and/or stenting (PTA/PTAS) or extracranial-intracranial (EC/IC) bypass surgery for patients with ICAS...

BACKGROUND: Post-thrombotic obstruction can be adequately treated by percutaneous transluminal angioplasty and stenting. This procedure is rapidly emerging as a minimally invasive alternative to traditional open surgical operations. However, the patient will be exposed to a significant amount of radiation during preoperative planning and operation. The aim of this study was to evaluate the amount of radiation exposure to patients during venous recanalization. METHODS: All patients undergoing endovenous recanalization from February 2016 to February 2018 were included in this study...

Background: Unstable angina (UA) has been one of the most common presentations of acute coronary syndrome. The numbers of admitted UA patients have been diminishing in the recent past. However, we are seeing higher costs and higher length of inpatient stay. We attempt to identify the trends and characteristics of length of hospitalization in patients admitted with UA using a nationally representative dataset. Methods: We used the nationwide inpatient sample (NIS) from 2002-2014 to assess the factors associated with length of stay in patients admitted with unstable angina using ICD-9-CM primary diagnosis codes (411...

A well-functioning vascular access is a mainstay to perform an efficient hemodialysis procedure, which directly affects the quality of life in hemodialysis patients. We use three main types of access: native arteriovenous fistula, arteriovenous graft, and central venous catheter. Arteriovenous fistula remains the first and best choice for chronic hemodialysis. It is the best access for longevity, the lowest related complications, and for this reason, arteriovenous fistula use is strongly recommended by guidelines from different countries, including Vietnam...
