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.

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.

Open surgical and endovascular conduits for difficult access during endovascular aortic aneurysm repair.

Endovascular aortic aneurysm repair has gained widespread acceptance as the primary method of treatment of abdominal and thoracic aortic aneurysms. Difficult access because of small, narrowed, tortuous, or severely calcified iliac and femoral arteries poses a significant challenge and remains a common cause of inadvertent arterial disruption and conversion to open repair. Vascular complications associated with difficult access are associated with major morbidity and mortality.
