Percutaneous transhepatic cholangiography with external drainage of obstructive biliary lesions.

Transhepatic cholangiography was performed in 83 patients using a technique of catheterization of the bile ducts and external drainage. After drainage, the jaundice decreased, and the condition of the patients improved preoperatively. Emergency exploratory examination had to be performed in two patients after the examination, in both because of bile leakage. The complication rate is lower than that for the 22 patients who did not undergo drainage in conjunction with percutaneous transhepatic cholangiography.

Control of hepatic tumor hemorrhage by transcatheter embolization with Ethibloc.

Two patients with abdominal hemorrhage from a hepatic tumor underwent transcatheter embolization using Ethibloc. The hemorrhage ceased rapidly in both patients. No complications related to the embolization procedure were observed. One patient is doing well after 4 years. The second patient died of extensive metastatic disease eleven weeks after embolization. Control angiography after 14 months and 2 weeks, respectively, demonstrated persistent occlusion of the embolized hepatic arteries. Ethibloc offers the advantage of permanent vascular occlusion and appears to be a safe and effective embolization material for partial occlusion of the hepatic arteries.

Vascular grafts in below-knee femoro-popliteal bypass. A comparative study.

In 40 patients below-knee femoro-popliteal bypass grafts (autogenous saphenous vein, ePTFE, ring-supported ePTFE, double-helix supported ePTFE, noncrimped coil-supported Dacron) have been analysed by an early postoperative angiography in 90 degree knee bent lateral position. Autogenous vein grafts almost constantly show an ideal position. Coil-supported Dacron as well as ring-supported ePTFE and double-helix-supported ePTFE proved to be a valuable substitute, whereas the conventional ePTFE bypass showed considerable kinking due to its minimal longitudinal elasticity. Those kinks lead to turbulence, jet phenomena and, in the long term, to neointimal proliferations. This might be the cause of late failures. The most important advantage of the three different ePTFE grafts in our experience is the possibility of thrombectomy at any interval after the operation.
