Partial versus complete arterial transection, fact versus fancy.

Traditionally, hemorrhage from the partially transected artery exceeds that from its completely divided counterpart. The clinical significance of this distinction is pertinent to the control of the hemorrhage in the field as well as in the operating room. To test the hypothesis the femoral arterial blood flow (Q) of seven anesthetized (pentobarbital, 30 mg/kg, IV) dogs, whose average weight was 19.

A nonheparinized muscle model for studies of ischemia-reperfusion injury.

An understanding of the basic metabolic, functional, and histologic features of skeletal muscle injury secondary to ischemia and reperfusion has thus far been hampered by the lack of an adequate animal model. We have developed an in vivo isolated skeletal muscle preparation amenable to ischemia-reperfusion studies and the investigation of therapeutic modalities. The model is autoperfused and, most importantly, nonheparinized.

A comparison of isobutyl 2-cyanoacrylate glue, fibrin adhesive, and oxidized regenerated cellulose for control of needle hole bleeding from polytetrafluoroethylene vascular prostheses.

Prolonged anastomotic and needle hole bleeding from synthetic vascular prostheses is a common surgical problem in heparinized patients and in the patient with a coagulopathy. The relative effectiveness of various hemostatic agents has not previously been determined by controlled comparisons. In this study 6 mm polytetrafluoroethylene (PTFE) vascular prostheses were used to perform carotid-carotid and femorofemoral bypasses in eight heparinized dogs.

Tuberculous retroperitoneal lymphadenopathy mimicking metastatic pancreatic carcinoma.

A case of retroperitoneal lymphadenopathy of tuberculous origin is reported. Despite clear representation of retroperitoneal lym-phadenopathy by abdominal ultrasonography and computerized tomography (CT), fine-needle aspiration was inconclusive. Exploratory laparotomy was necessary to make the diagnosis.
