The results of surgical treatment of 17 patients with complete acrominoclavicular dislocation are presented. The operative procedure described is technically easy, gives good results, has few complications which often follow operations using metallic fixation devices. A second operation to remove fixation devices is avoided.
Popliteal vessel injury still carries a high amputation rate despite the progresses which have been made in vascular surgery. Three patients with such injuries treated with vascular repair are reported and a review of the recent literature is given. Prognostic factors as early diagnosis, delay in treatment, associated injuries as fracture/dislocation and venous injury, soft tissue injuries, adequate vascular repair, and postoperative complications are discussed.

A case of the rare portosystemic arteriovenous fistula is presented. This lesion, although basically simple, is not trivial. The predominant cause of death is variceal bleeding. Most often, the fistulas are due to rupture of an aneurysm of the hepatic or splenic artery, gunshot wound of the abdomen, or the use of mass ligature during abdominal surgery. The treatment is excision when possible, reconstruction of the vessels when vessels cannot be sacrificed, and ligation when everything else fails. Angiography is indispensible in defining the fistula. Because of the circulatory strain produced by these fistulas and of the danger of portal hypertension even in the asymptomatic patient, the presence of a portosystemic arteriovenous fistula is sufficient indication for surgical treatment.
A typical case of liver abscess is reported. The mortality rate of this surgical entity, previously very high, has been reduced markedly in recent years. The most important factors are the new diagnostic developments such as liver scans and coeliacography, making an early and exact diagnosis possible and thus forming the basis for an early and adequate surgical drainage.
