Some normal variations of knee arthrograms and their anatomical significance.

Knees obtained after amputation were fixed with formalin after the joint space was distended with air. The joints were then either dissected or frozen and sectioned vertically with a band saw in planes comparable to those visualized during arthrography. By comparing these anatomical specimens and arthrograms, the anatomical explanations for some normal variations visible or arthrograms could be identified. These variations included the appearance of the popliteus tendon and the posterior part of the lateral meniscus, the air-filled cul-de-sac posterior to the medial meniscus, and the interconnections of the joint space and the gastrocnemius and semimembranosus bursae.

An angiographic approach to hepatobiliary diseases.

Abdominal aortography and celiacomesenteric angiography preceded or followed by cholangiography and portography provide the most comprehensive approach and thorough angiographic evaluation of hepatobiliary-pancreatic diseases. Transhepatic catheterization and subsequent embolization of gastroesophageal veins are of great value in actively bleeding, as well as in stable, varices. Exit embolization of the needle tract minimizes the possibility of the leakage of blood or of bile.

Arteriographic bleeding: a new sign.

A new sign of arteriographic bleeding, diastolic clearance of angiographic contrast medium selectively from the bleeding vessel, is described. The use of this sign must be confined to rapidly bleeding end-vessel distributions or when nonopacified collateral circulation is not a consideration. It should not be confused with the normal washout of contrast substance in areas of multiple parent vessel collateral circulation where intermittent opacification is a normal feature.
