The surgical management of patients whose pulmonary arteries are discontinuous from the ventricular mass depends in part on adequate visualization and quantification of the pulmonary arteries. Pulmonary vein wedge angiography has proven effective technique in demonstrating the true mediastinal(intrapericardial) pulmonary arteries(when present) when standard anterograde injections do not suffice. Pulmonary vein wedge angiography was performed in 11 patients during cardiac catheterization at Serverance Hospital Yonsei University College of Medicine between June, 1984 and December, 1985. In all the patients, venous angiography gave a more complete, clear picture of the pulmonary arteries. We feel that pulmonary venous wedge angiography often is superior to and at least complements standard angiographic methods of opacifying the pulmonary artries in patients with pulmonary atresia or occluded pulmonary arteries. We recommend it as a routine part of the evaluation of these patients.

Endoscopic variceal ligation (EVL) is effective for the management of bleeding esophageal varices, and its use is widespread now. EVL necessitates the use of overtubes. Two primary techniques have been used for overtube placement; one is with endoscope, and the other is with bougie dilator. Overtube placement with endoseope is not without risk. There are reportd of esophageal or pharyngeal laceration or perforation. Overtube placement with bougie dilator circumvents this risk, but it is rather cumbersome to use. The authors devised a safe and easy method for overtube placement, and applied it to a number of patients to test its safety and convenience. First, overtube-dilator assembly was prepared as follows. A Rigiflex achalasia dilator (balloon 30mm OD, 10cm length; Microvasive Co) was lubricated and inserted into the overtube. A tenth of the balloon tip was protruded out of the overtube, then the balloon was insufflated with air at 10-15 psi. Second, standard endoscopy was performed, followed by placement of guide wire in the stomach. Overtube-dilator assembly was lubricated and introduced over the wire as a rail. Once the overtube was properly positioned, the balloon was deflated, and the balloon and wire were removed as a whole, which completed overtube placement. For 65 patients with esophageal variceal bleeding, 82 procedures of EVL were performed using the new technique. Overtube-dilator assembly was easy to prepare and handle. This technique added little time to the procedure and minimizes patients discomfort. No patient suffered major complications such as bleeding, laceration or perforation. This novel method for overtube placement was safe and convenient for use in EVL. It can also be applied to other procedures using overtube such as endoscopic foreign body removal.

Percutaneous biliary dilation was done in 3 patients with benign strictures. The first case was 50-year-oldmale who had multiple intrahepatic stones with biliary stricture. The second 46-year-old female and the third25-year-old male suffered from recurrent cholangitis with benign stricture of anastomotic site aftercholedochojejunostomy. In the first case, a 6mm diameter Grunzig dilatation balloon catheter was introducedthrough the T-tube tract. In the second case, the stricture was dilated with two balloons of 5mm and 8 mm in eachdiameter sequentially thorugh the U-loop tract formed by surgically made jejunostomy and percutaneous transhepaticpuncture. In the third case, the dilatation catheter was introduced through the percutaneous transhepatic tract.Dilatation was made with a pressure of 5 to 10 atmospheres for 1 to 3 minutes duration for 3 times. In all 3cases, the structures were successfully dilated and in second and third cases internal stent was left across thelesion for prevention of restenosis.
