[Vascular injuries in everyday practice]

It was the objective of this retrospective study to analyse the causes of injury, surgical approaches, outcome, and complications in patients with vascular trauma and to report our experience with vein homografts for arterial reconstruction in the upper and lower limbs and cervicothoracic region in patients operated on over a period between 1981-2001.In 128 patients with peripheral arterial injuries the mechanism was direct penetration in 90 cases and blunt injury in 20 cases. In 4 cases a chronic damage (false aneurysm, AV fistula) was observed. Isolated vascular trauma was present in 97 patients (75.8%), 31 cases (24.2%) were aggravated by concomitant bone fractures, and nerve or soft tissue damage. Most frequently injured vessels were the superficial femoral (22.6%), crural (22.6%), and ulnar and radial (13.2%) arteries. 16 patients with penetrating cervicothoracic arterial injuries were registered during this period. 8 patients underwent emergency exploration and 8 patients angiography prior urgent exploration.Saphenous vein interposition grafting was applied with good results in 34 patients, polytetrafluoroethylene and Dacron grafts were used in eight cases, end to end anastomosis in 12 cases, venous bypasses in 5 cases, venous patches in 7 cases. 17 patients underwent arterial repair and 9 venous repair. Vein homografts as an arterial substitute were implanted in 8 patients. Five secondary amputations were performed and five patients died. The limb salvage rate was 95% and the primary patency rate of vein homografts was 75% (excluded primary amputations). The penetrating cervicothoracic injuries were all repaired with improvement in level of consciousness and neurological deficit when present.Most vascular injuries of the extremities can be managed successfully unless associated with severe concomitant damage of the bones, nerves and soft tissues. In the absence of suitable autologous vein grafts, homografts appear to be an interesting alternative for arterial repair. In penetrating cervicothoracic vascular injuries immediate operative repair offers the best chance of recovery.
