OBJECTIVE We evaluated therapeutic microcoil embolization in a group of patients with severe colonic hemorrhage. MATERIALS AND METHODS Twenty-seven patients with severe colonic bleeding due to diverticular disease (n = 19), angiodysplasia (n = 6), cecal ulcer (n = 1), or unknown cause (n = 1) underwent attempted microcoil embolization (n = 25).(More)
OBJECTIVE We conducted a retrospective study to evaluate two different types of percutaneous fluoroscopic gastrostomy procedures and catheters. MATERIALS AND METHODS Between July 8, 1999, and August 4, 2000, 80 percutaneous gastrostomy catheters were placed in 80 patients in 80 attempts. Twenty-five 16-, 18-, or 20-French balloon-retained catheters and 55(More)
The purpose of this study was to review the use, safety, and efficacy of retrievable inferior vena cava (IVC) filters in their first 5 years of availability at our institution. Comparison was made with permanent filters placed in the same period. A retrospective review of IVC filter implantations was performed from September, 1999, to September, 2004, in(More)
The OptEase vena cave filter (Cordis, Piscataway, NJ) is commercially available as a retrievable or permanent filter with short recommended indwelling time, presumably due to extensive contact of the filter side struts with the inferior vena cava wall and subsequent neointimal hyperplasia leading to incorporation. Our purpose was to evaluate OptEase filter(More)
To determine the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) creation in patients with liver cirrhosis complicated by thrombosed portal vein. This study reviewed 15 cases of TIPS creation in 15 cirrhotic patients with portal vein thrombosis at our institution over an 8-year period. There were 2 women and 13 men with a mean(More)
With modern cross-sectional imaging techniques, cystic lesions are very common and usually incidental findings, especially if small. However, when cysts enlarge, become infected, bleed, or undergo torsion, they can be symptomatic, and percutaneous drainage can be effective in the management. When cysts recur after aspiration, which is often the case for(More)
Although recommended placement of IVC filters is with their tips positioned at the level of the renal vein inflow, in practice, adherence is limited due to clinical situation or IVC anatomy. We seek to evaluate the indwelling and retrieval complications of IVC filters based on their specific position within the infrarenal IVC. Retrospective, single(More)
We report a case of a 12-year-old girl with a mesenteric pseudoaneurysm and abdominal tuberculosis presenting with massive lower gastrointestinal hemorrhage requiring multiple blood transfusions. The pseudoaneurysm was treated successfully with transarterial microcoil embolization. Pseudoaneurysms are a rare and life-threatening complication of tuberculosis(More)
To determine the safety and efficacy of conversion of non-tunneled (temporary) catheters to tunneled catheters in hemodialysis patients. A retrospective review of 112 consecutive conversions in 111 patients was performed over a period of 4 years. Fourteen patients were lost to follow-up. The remaining 97 patients had clinical follow-up. Temporary catheters(More)
We appreciate the input regarding our recently published paper on TIPS creation in patients with cirrhosis and concomitant portal vein thrombosis (PVT) [1]. It is interesting to note that our data correlated well with those of Senzolo et al. [2] as described in their letter, although their study included of 12 non-cirrhotic patients with PVT. We agree that(More)
