title: [Radiological interventional procedures for the acute abdomen].
abstract: In patients with acute thrombo-embolic occlusion of the superior mesenteric artery, catheter-assisted thrombolytic therapy represents a procedure of increasing importance in addition to surgery and intensive care treatment. The thrombolytic drugs utilized for this purpose are urokinase, streptokinase and recombinant tissue plasminogen activator (rtPA).Therapeutic embolization is predominantly used in the treatment of arterial bleeding from the gastro-intestinal tract, the liver, the intestines (due to an aneurysm or vascular malformation) and in bleeding from intestinal anastomoses. Polyvinyl alcohol particles, embospheres, gelfoam and microcoils can be utilized as embolic agents. Percutaneous transhepatic cholangiodrainage and stent implantation are applied in patients with biliary obstructions caused by inoperable tumors of the gall bladder or bile ducts, of the pancreatic head or duodenum and by metastases located in the liver parenchyma or hepatic hilum.Image-guided percutaneous drainage is a valuable option in the management of abscesses in the peritoneal cavity; less common indications are lymphoceles, biliomas, urinomas, hematomas, necrosis and pseudocysts.
