PURPOSE To prospectively compare radiologically created pigtail gastrostomy (PG), in which the tube is inserted directly through the abdominal wall, versus peroral image-guided gastrostomy (POG), in which the tube is inserted through the mouth. Pain profiles (primary outcome measure), fluoroscopy times, total room times, technical success, complications,(More)
PURPOSE To compare pain levels as measured by visual analog scale (VAS) and analgesic requirement between intercostal and anterior subcostal ultrasound (US)-guided biopsy. MATERIALS AND METHODS Seventy consecutive patients were randomized to undergo biopsy via an intercostal (n = 33) or subcostal (n = 37) approach. The groups were matched with regard to(More)
Genes play a very important role in the etiology of hypertension. This paper reviews the current pool of candidate genes for human hypertension. Some of the genes studied in rat models of hypertension are also discussed. The methods for studying the genetics of hypertension are reviewed. A discussion of the role of cardiac gene libraries and gene databases(More)
PURPOSE Ultrahigh-pressure (UHP) balloon catheters were compared with high-pressure (HP) balloon catheters to determine if there was a difference in patency after percutaneous transluminal angioplasty (PTA) of venous anastomotic stenoses. MATERIALS AND METHODS A retrospective study was conducted from January 2001 to September 2005 that included 22(More)
PURPOSE Describe outcomes after endovascular intervention of TransAtlantic Inter-Society Consensus C and D femoro-popliteal disease. MATERIALS AND METHODS Retrospective cohort study. Patient demographics, ankle-brachial indices, and lesion details were analyzed from a prospectively maintained database. In all, 980 limbs treated with percutaneous(More)
PURPOSE To assess efficacy of two different techniques of lidocaine injection in the uterine arteries to reduce pain following uterine artery embolization (UAE) for leiomyomas. MATERIALS AND METHODS This prospective randomized single-blinded study was performed with 60 patients enrolled between November 2014 and December 2015 equally randomized to 3 arms.(More)
BACKGROUND Atherosclerotic peripheral arterial disease (PAD) can lead to disabling ischemia and limb loss. Treatment modalities have included risk factor optimization through life-style modifications and medications, or operative approaches using both open and minimally invasive techniques, such as balloon angioplasty. Drug-eluting balloon (DEB) angioplasty(More)
OBJECTIVE It has been accepted that the implementation of the a preprocedural surgical checklist can reduce perioperative morbidity and mortality in the operating suite. From this success, there has been focus on applying this intervention to other clinical areas. The objective of this study was to evaluate the acceptance and culture change after the(More)
PURPOSE To assess the pullout force (POF) of bridging stent-grafts used in thoracoabdominal stent-grafts and iliac bifurcated grafts. METHODS In an experimental setup, the POFs of Viabahn or Fluency with or without a Zilver stent were measured when deployed into the renal and celiac branches of a Zenith thoracoabdominal cuff-bearing branched stent-graft.(More)
