Complications of central venous catheterization at a vascular surgery service in a teaching hospital: a prospective cohort study.

Background: Central venous catheters are essential for management of hospitalized patients, but their insertion is subject to complications that can make them unusable and/or cause patient morbidity. There are few data on the incidence of these complications and the variables associated with these outcomes in Brazil.

Objectives: To determine the incidence of mechanical complications and failures of short stay central venous catheters fitted by the vascular surgery service at a teaching hospital and identify variables associated with their occurrence.

6-Month Follow-up of Lateral Femoral Circumflex Artery Embolization to Control Pain Related to Hip Osteoarthritis and Greater Trochanteric Pain Syndrome.

Purpose: To present the preliminary results of a cohort of 13 patients with hip osteoarthritis (OA) and great trochanteric pain syndrome (GTPS) refractory to conservative management or physical therapy and no indication for surgery treated with embolization of the lateral femoral circumflex artery.

Material And Methods: This is a single-center prospective cohort from July 2019 to September 2020. Visual analogue scale (VAS) and Western Ontario and MacMaster Universities (WOMAC) were used to compare the symptoms before and after 6-month follow-up.

GAUCHO - Trial Genicular Artery Embolization Using Imipenem/Cilastatin vs. Microsphere for Knee Osteoarthritis: A Randomized Controlled Trial.

Genicular artery embolization (GAE) has emerged as a treatment option to improve quality of life in patients suffering from moderate-to-severe pain refractory to conservative treatment of knee osteoarthritis, with encouraging results. This paper describes the study protocol of a single-center, double-blind, randomized controlled trial designed to evaluate and compare the safety and efficacy of GAE using imipenem/cilastatin vs. microspheres for the treatment of moderate-to-severe pain associated with knee osteoarthritis.

Population-Based Trends in Amputations and Revascularizations for Peripheral Artery Disease From 1990 to 2009.

Objective: To determine trends in amputations and revascularizations for peripheral artery disease (PAD) in a well-defined population.

Methods: A population-based cohort study of Olmsted County, Minnesota, residents with PAD undergoing amputation or revascularization was conducted between January 1, 1990, and December 31, 2009. Population-level 5-year incidence trends for endovascular, open surgical, and hybrid revascularizations and major and minor amputations were determined.

Coarctation of the abdominal aorta associated with renovascular hypertension and incapacitating claudication: repair with iliac-birenal bypass and paving and cracking technique.

Coarctation of the abdominal aorta is a rare etiology of intermittent claudication and refractory hypertension. Treatment is complex and requires knowledge of several vascular reconstruction techniques. We report a case of aortic coarctation at the level of the renal arteries, describing its treatment and presenting a literature review.

Prevalence of left iliac vein compression on computed tomography scans from a population.

Background: May-Thurner syndrome (MTS) is defined as compression of the left iliac vein between the right iliac artery and the lumbar vertebral body in the presence of signs and symptoms of unilateral left chronic venous insufficiency. However, imaging findings of compression are not manifest in symptoms of the syndrome in all subjects.

Objectives: To evaluate findings of compression in an asymptomatic population.

Short-term follow-up of embolization of hip synovitis.

Background: Osteoarthritis (OA) is the most frequent joint disease, affecting 10% of men and 18% of women older than 60 years worldwide. Traditionally, treatment is based in pain management with joint replacement of end-stage disease. In this setting, transcatheter embolization has emerged as an alternative in reduction of pain in patients with OA.

Pelvic congestion syndrome and embolization of pelvic varicose veins.

Pelvic congestion syndrome (PGS) is defined as chronic pelvic pain for more than 6 months associated with perineal and vulvar varicose veins caused by reflux or obstruction in gonadal, gluteal, or parauterine veins. PGS accounts for 16-31% of cases of chronic pelvic pain, and is usually diagnosed in the third and fourth decades of life. Interest in this condition among vascular surgeons has been increasing over recent years because of its association with venous insufficiency of the lower limbs.

Technical aspects of repair of juxtarenal abdominal aortic aneurysms using the Zenith fenestrated endovascular stent graft.

Fenestrated endovascular aortic repair has been used with increasing frequency to treat complex aortic aneurysms. The Zenith fenestrated stent graft system (Cook Medical Inc, Brisbane, Queensland, Australia) was approved for commercial use in the United States in April 2012, offering a custom-made design with up to three fenestrations to treat short-neck infrarenal and juxtarenal abdominal aortic aneurysms. This report and the Video presentation (online only) summarize the preoperative planning, stent graft design, and technique of implantation of a Zenith fenestrated stent graft using a totally percutaneous approach in an 80-year-old female patient with a 6-cm juxtarenal abdominal aortic aneurysm.

Preloaded guidewires to facilitate endovascular repair of thoracoabdominal aortic aneurysm using a physician-modified branched stent graft.

Branched stent grafts have been widely applied to treat complex aortic aneurysms. The technique often requires brachial or axillary approach to provide antegrade access to directional branches, which are bridged to target visceral arteries by self-expandable stent grafts. Preloaded guidewire catheterization may facilitate access into directional branches, decreasing or eliminating catheter manipulations required during this step of the procedure.

The use of cryopreserved aortoiliac allograft for aortic reconstruction in the United States.

Background: Aortic infections, even with treatment, have a high mortality and risk of recurrent infection and limb loss. Cryopreserved aortoiliac allograft (CAA) has been proposed for aortic reconstruction to improve outcomes in this high-risk population.

Methods: A multicenter study using a standardized database was performed at 14 of the 20 highest volume institutions that used CAA for aortic reconstruction in the setting of infection or those at high risk for prosthetic graft infection.

Pelvic revascularization during endovascular aortic aneurysm repair.

Endovascular repair of aortic aneurysms (EVAR) has gained widespread acceptance in the treatment of abdominal aortic aneurysms (AAAs). Prospective studies have shown advantages compared with open surgical repair, including decreased blood loss, operating time, hospital stay, morbidity, and mortality. Approximately 30% of patients treated by EVAR have ectatic or aneurysmal common iliac arteries not suitable for distal sealing zones.
