Five thousand seven hundred sixty cardiovascular injuries in 4459 patients. Epidemiologic evolution 1958 to 1987.

Large epidemiologic analyses of cardiovascular injuries have been limited to studies of military campaigns compiled from many surgeons working in many hospitals with variable protocols. A detailed civilian vascular trauma registry provides a unique opportunity for an epidemiologic evolutionary profile. During the last 30 years in a single civilian trauma center directed by a consistent evaluation and treatment philosophy, 4459 patients were treated for 5760 cardiovascular injuries. Eighty-six per cent of the patients were male, and the average age was 30.0 years. Penetrating trauma was the etiology in more than 90% (GSW,51.5%; SW,31.1%; SGW,6.8%). All other injuries were iatrogenic or secondary to blunt trauma. Truncal injuries (including the neck) accounted for 66% of all injuries treated, while lower extremity injuries (including the groin) accounted for only 19%. Injuries to the abdominal vasculature accounted for 33.7% of the injuries. One thousand fifty-seven patients had 2 or more concurrent vascular injuries, and 32 patients had 4 or more separate vascular injuries. The 27 patients-per-year average of the early 1960s has risen to a current average of 213 patients per year. Economic and population factors influenced wounding agents and injury patterns during the evaluation period. This extensive civilian series presents epidemiologic profiles that are distinctly different from military reports and serves as a guide for current trauma center and health planners.

Civilian trauma in the 1980s. A 1-year experience with 456 vascular and cardiac injuries.

During 1982, 312 patients with 408 vascular injuries and 48 cardiac injuries were seen. Two or more vascular or cardiac injuries were present in 34% of patients. Over 87% of injuries were secondary to gunshot wounds, stab wounds, or shotgun wounds. Vascular injuries were most commonly seen in the extremities (39.9%) or abdomen (31.9%). The most common arterial injuries occurred in the brachial artery (39 patients), while the most common venous injuries occurred in the internal jugular vein (26 patients). Arterial injuries were treated by the insertion of substitute vascular conduits (33.9%), ligation (22.6%), lateral arteriorrhaphy (18.6%), or end-to-end anastomosis (15.4%). Venous injuries were treated by lateral venorrhaphy (63.7%) or ligation (25.1%). In the 272 patients admitted with only vascular injuries, survival was 84.2%. Cardiac injuries in 38 patients most commonly occurred in the right ventricle (50%) and right atrium (25%). In the 34 patients who had only cardiac injuries and less than 4 minutes of prehospital cardiopulmonary arrest prior to arrival in the emergency center, survival was 64.7%.

Complete occlusion of the infrarenal abdominal aorta: management and results in 64 patients.

Sixty-four patients with complete occlusion of the infrarenal abdominal aorta were reviewed. The clinical findings, diagnostic procedures, and surgical management are described. Sixty-one patients underwent thromboendarterectomy and bypass grafts from the infrarenal abdominal aorta to the iliac or common femoral arteries. Because purulent material was found in the retroperitoneum of two patients, the proximal anastomosis was performed to the descending thoracic aorta in one patient and to the upper abdominal aorta in the other. One patient underwent thromboendarterectomy and patch graft angioplasty. The hospital mortality rate was 4.6 percent. Sixty-one patients discharged from the hospital were followed (average length of follow-up was 37 months). There were three late deaths (4.9 percent). Two patients have had occlusion of one limb of their bypass grafts and, along with four others, have developed recurrent symptoms of vascular insufficiency of the lower extremities. These symptoms were due to progressive atherosclerotic occlusive disease of the distal arterial tree for which additional distal procedures were required.

Double prosthetic aortic valve. Case report.

A 55-year-old man underwent insection of a Hufnagel valve into his descending thoracic aorta for aortic valve insufficiency 18 years ago. He remained asymptomatic for 16 years. Because of progressive left ventricular failure his incompetent aortic valve was replaced with a De Bakey carbon ball aortic valve prosthesis 2 years later. Currently, 21 months after the operation, he is doing well with two aortic valves. Review of the literature suggests that he is the first patient reported with two aortic valves functioning concomitantly and one of the longest surviving patients with a Hufnagel valve.

Inadvertent femoral artery "stripping": surgical management.

Following "vein stripping" for varicosities, two patients were referred to our service for evaluation of arterial insufficiency of the lower extremities. Both patients had had surgical interruption of the femoral arterial system which required reconstruction. This paper emphasizes the importance of understanding surgical anatomy and presents the techniques of successful surgical management of both cases.
