Among 1142 patients with head injuries hospitalized in the Neurosurgery Department of Gazi University Medical School during the period between 1979 and 1992, 583 had initial CT scans. A retrospective analysis of these initial CT images revealed intracranial air on admission in only 21 cases. These were classified as acute traumatic intracranial pneumocephalus: a potentially serious complication of head injury. CT scans were re-evaluated so as to reveal whether air was situated in the epidural, subdural, or subarachnoid spaces or intracerebrally; whether associated space-occupying lesions were present and whether the air bubbles were single or multiple. Clinical data such as the presence of persistent rhinorrhea and/or otorrhea, tension pneumocephalus, severity and type of trauma, and outcome were were also assessed to determine the significance of this rare finding.

A new technique of arteriovenous anastomosis is presented which lessens the complication of intravascular turbulence and thrombosis seen with elongated and narrow anastomotic segments. The axillary artery and jugular vein were anastomosed in 10 ZBZ-Cara rats using microsurgical techniques. The jugular vein was prepared as a tubular structure facilitating two end-to-end anastomoses rather than the customary end-to-side technique. Angiographic patency was demonstrated at 3 weeks in 10/10 rats. Two of ten anastomotic segments were considered quite narrow; however, angiographic demonstration of flow was excellent.
