Rural vascular trauma: a twenty-year review.
A 20-year review documented 248 vascular injuries in 210 patients from principally rural areas. The average time between injury and treatment from 1970 to 1983 was 6 hours. Between 1983 to 1990, when 46% of patients were transported by helicopter, the average delay was 4 hours. Blunt trauma (41%, with 29% motor vehicle accidents and 12% farm/industrial accidents) caused the most severe injuries and accounted for most amputations (89%) and deaths (80%). All of the blunt trauma patients had associated injuries. Penetrating injuries occurred in 59% of the patients and accounted for 11% of the amputations and 20% of the deaths. Extremity vessels were injured 73% of the time (upper extremity, 47%; lower extremity, 26%). Eighty-seven percent of the vessels injured were arteries and 13% were major venous injuries. Preoperative arteriograms were obtained in 30% of our patients. Vascular injury was determined in the others at the time of operative exploration. Vascular repair included direct anastomosis or lateral suture repair (51%), autogenous vein graft (16%), synthetic graft (6%), and ligation (19%). Primary amputation and thrombectomy were other (8%) initial treatments. In the past 10 years concomitant major peripheral venous injuries were repaired in six patients (one amputation) and ligated in one patient (no amputation). The mortality rates (4.8% total) for patients with blunt and penetrating trauma were 9.3% and 1.6%, respectively. Survival rates have not improved since the implementation of a helicopter transport system in 1983, but the amputation rate declined from 18% to 7%.
