PURPOSE To evaluate the long-term effectiveness of the percutaneous treatment of portal venous stenoses in children and adolescents with reduced-size hepatic transplants. MATERIALS AND METHODS During the past 5 years, percutaneous transhepatic balloon venoplasty was attempted in 25 children and adolescents with anastomotic portal venous stenoses that(More)
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 evaluated the technical success and complications of percutaneous transhepatic biliary drainage in patients with nondilated intrahepatic bile ducts. MATERIALS AND METHODS Between January 1, 1996, and August 31, 1998, 130 percutaneous transhepatic biliary drainage procedures were performed on patients with nondilated intrahepatic bile ducts.(More)
OBJECTIVE The aim of this study was to describe the appearances obtained and the pitfalls involved with the use of Doppler sonography for detecting portal vein stenoses after surgery in 198 recipients of pediatric reduced-size transplants. SUBJECTS AND METHODS We analyzed sonographic and Doppler studies after surgery for 167 children (average, 2.5 years(More)
OBJECTIVE Two different types of percutaneous fluoroscopic gastrostomy procedures were prospectively evaluated. SUBJECTS AND METHODS Between January 1, 1998, and August 10, 1999, 127 percutaneous gastrostomy catheters were placed in 128 patients in 128 attempts. Seventy-five 12- or 14-French pigtail-retained catheters and fifty-two 20-French(More)
The purpose of this article is to review the angiographic appearance of the major visceral arteries, the more common variants, their embryologic origins, and some of the most common sources of collateral flow. A brief review of the physiology of the mesenteric circulation is also provided, including a discussion of the intrinsic and extrinsic mechanisms of(More)
OBJECTIVE In children with liver transplants, percutaneous transhepatic cholangiography has a critical role in evaluation and treatment of biliary complications. The purpose of this study was to evaluate the technical success and complication rates of percutaneous transhepatic cholangiography and biliary drain placement in children who underwent liver(More)
OBJECTIVE We conducted a retrospective study to evaluate two different types of percutaneous fluoroscopic gastrostomy procedures and catheters.
