Symptomatic benign prostatic hyperplasia (BPH) typically occurs in the sixth and seventh decades, and the most frequent obstructive urinary symptoms are hesitancy, decreased urinary stream, sensation of incomplete emptying, nocturia, frequency, and urgency. Various medications, specifically 5-α-reductase inhibitors and selective α-blockers, can decrease the(More)
Prostatic artery embolization requires a refined technique to achieve good imaging and clinical success. The PErFecTED (Proximal Embolization First, Then Embolize Distal) technique has produced greater prostate ischemia and infarction than previously described methods with clinical improvement of lower urinary symptoms and lower recurrence rates. The(More)
PURPOSE To describe the safety and efficacy of prostatic artery embolization (PAE) with spherical microparticles to treat lower urinary tract symptoms associated with benign prostatic hyperplasia in patients with prostate volume > 90 g. MATERIALS AND METHODS This prospective, single-center, single-arm study was conducted in 35 patients with prostate(More)
To compare clinical and urodynamic results of transurethral resection of the prostate (TURP) to original and PErFecTED prostate artery embolization (PAE) methods for benign prostatic hyperplasia. We prospectively randomized 30 patients to receive TURP or original PAE (oPAE) and compared them to a cohort of patients treated by PErFecTED PAE, with a minimum(More)
The purpose of this study was to evaluate the mid- and long-term results of percutaneous transhepatic cholangiography (PTC) and biliary drainage in children with isolated bilioenteric anastomotic stenosis (BAS) after pediatric liver transplantation. Sixty-four children underwent PTC from March 1993 to May 2008. Nineteen cholangiograms were normal; 10 showed(More)
The purpose of this study was to describe the preliminary results of prophylactic temporary balloon occlusion of the internal iliac arteries for bleeding control in patients with placenta accreta during cesarean hysterectomy. From May 2006 to March 2010, 21 patients diagnosed with placenta accreta using ultrasound and/or magnetic resonance imaging were(More)
Prostatic artery embolization (PAE) is an alternative treatment for benign prostatic hyperplasia. Complications are primarily related to non-target embolization. We report a case of ischemic rectitis in a 76-year-old man with significant lower urinary tract symptoms due to benign prostatic hyperplasia, probably related to nontarget embolization. Magnetic(More)
To describe and categorize the angiographic findings regarding prostatic vascularization, propose an anatomic classification, and discuss its implications for the PAE procedure. Angiographic findings from 143 PAE procedures were reviewed retrospectively, and the origin of the inferior vesical artery (IVA) was classified into five subtypes as follows: type(More)
INTRODUCTION The incidence of intravascular embolization of venous catheters reported in the world medical literature corresponds to 1% of all the described complications. However, its mortality rate may vary between 24 to 60%. Catheter malfunction is the most likely signal of embolization, since patients are usually asymptomatic. OBJECTIVE To report the(More)
Although operative techniques in hepatic transplantation have reduced the time and mortality on waiting lists, the rate of vascular complications associated with these techniques has increased. Stenosis or thrombosis of the portal vein is an infrequent complication, and if present, surgical treatment is considered the traditional management. This article(More)
