[Scope and late results of transluminal angioplasty (author's transl)].

Transluminal angioplasty represents an alternative to operation in treatment of arteriosclerotic stenosing and obstructive lesions. The authors report their experience since 1973 with 64 cases treated in the iliac, femoral or popliteal region and 2 cases of stenosis of the renal artery. Arterial tract may be dilated or recanalized depending on stage of the lesion. Patient's follow up with angiography and flow controls showed 70% of success for dilatation and 60% for recanalization at 5 and 4 years respectively. The rate of success and low incidence of complications are particularly encouraging and suggest this type of treatment not only for inoperable high risk patients but also as an elective procedure in well selected patients. Moreover technical facilities and skill of the operator may extend the applicability of angioplasty to treatment of other stenosed segments at the level of renal, coronary and visceral arteries and of iliac veins.

Emergency transhepatic obliteration of bleeding varices.

Transhepatic obliteration of gastroesophageal varices was performed in 18 actively bleeding patients. The success of the procedure was related to the complete obliteration of the varices, as demonstrated by their disappearance at angiography. In 13 of the 14 patients in whom obliteration was complete, bleeding did not recur. Three of the 13 died of hepatic insufficiency within 18 days of embolization, and three refused surgery and were lost to follow-up. The remaining seven patients had portacaval or mesocaval shunts, and are doing well at a follow-up of 12 months. Transhepatic obliteration has, therefore, proved to be an effective emergency procedure in patients who will be acceptable surgical candidates at a later date.

Angiographic diagnosis of jugular venous system dilatation in children. A report of five cases.

We report five children with a soft mass in the neck due to congenital jugular venous ectasia. Three had fusiform dilatation of the internal jugular vein, which in one case was associated with dilatation of the ipselateral external jugular vein. Two children had aneurysmal dilatation of the superficial cervical communicating vein. The first four cases required angiographic studies for final diagnosis. Venography via the femoral vein was most valuable for visualization of the dilated segments of internal jugular veins but failed to show the vascular mass communicating with the superficial vein of the neck. These were best visualized by direct injection of the contrast medium into the vessel. In the fifth case a correct diagnosis was obtained with xeroradiography alone.

Percutaneous transhepatic portal venography in the diagnosis and management of gastroesophageal varices.

Percutaneous transhepatic portal venography is a relatively safe method of obtaining both physiologic and morphologic information in patients with portal hypertension. Precise "road mapping" is performed, as well as measurement of free portal pressure. Additionally, transcatheter obliteration of gastroesophageal varices may produce effective cessation of hemorrhage in patients bleeding from this site, as was done on an emergency basis after failure of intra-arterial vasopressin infusion.
