Recurrent bleeding after variceal hemorrhage: predictive value of portal venous duplex sonography.

Objective: Risk assessment of recurrent variceal bleeding is essential for therapeutic decisions and is usually performed by endoscopy of the upper gastrointestinal tract. We studied the value of portal venous duplex sonography in predicting subsequent variceal bleeding in patients with cirrhosis.

Subjects And Methods: Thirty patients with cirrhosis who received sclerotherapy because of acute variceal hemorrhage for the first time (hemorrhage group), 30 patients with cirrhosis who had no previous hemorrhage (nonhemorrhage group), and 30 control subjects were examined prospectively.

The role of colour flow duplex screening in infra-inguinal vein grafts.

To assess the indications for routine colour flow duplex surveillance, 43 infra-inguinal autogenous vein grafts were prospectively entered into a surveillance protocol. Screening consisted of measurements of ankle brachial indices (ABIs) and colour flow duplex imaging of the entire graft length. Twelve significant stenoses have been detected in 10 grafts (23%) using duplex, all within 6 months of surgery.

[Changes in diagnostic imaging of non-Hodgkin's lymphoma in recent years].

The following examinations have been carried out with various methods of diagnostic imaging: 148 CT, 69 US, 56 Ly. Data on the rate of accuracy of the various methods of examination in the individual abdominal regions. CT examinations rose from 1980 to 1985 from 83 percent to 100 percent.
