Gunshot injuries of the abdominal aorta: a continuing challenge.

This is a retrospective study of 57 patients with gunshot injuries of the abdominal aorta. The aortic repair was achieved by various means: lateral aortorraphy, patch aortoplasty and graft insertion. There was an 85 per cent mortality rate from bleeding or secondary coagulopathy directly related to the aortic injuries. The need for resuscitative thoracotomy, shock, lack of response to fluid resuscitation and intraperitoneal bleeding were directly related to mortality. We feel that shortening of prehospital transfer time will increase the absolute number of patients surviving this grave injury.

Gunshot arterial injuries to the groin: comparison of iliac and femoral injuries.

In a prospective study of 69 patients with gunshot arterial injuries to the groin, there were 18 patients with iliac and 51 with femoral artery injuries. In the former group, the majority of patients were admitted with gross physiological derangement that did not respond to pre-operative resuscitation, so were taken directly to theatre. There was a 39 per cent peri-operative mortality. A prompt operation is mandatory to improve the chances of survival of patients with this injury. In the latter group all patients responded to pre-operative resuscitation and in the great majority, the diagnosis was established by the presence of 'hard' signs of arterial injury alone. There was a 4 per cent amputation rate and no mortality.

Diaphragmatic herniation after penetrating trauma.

A study was made of 45 patients with diaphragmatic herniation after penetrating trauma. In 29 the diagnosis was established during the first admission (early presentation) and in 16 during a subsequent admission (delayed presentation). The mortality rate in the early presentation group was 3 per cent compared with 25 per cent in the delayed presentation group. The presence of gangrenous or perforated abdominal viscus in the chest cavity was the single most common and severe aggravating factor. The need for diagnosis of diaphragmatic herniation during the initial admission is emphasized. As isolated diaphragmatic injuries provide few helpful clinical features to aid diagnosis, appropriate investigations and good follow-up are of paramount importance in preventing late herniation of intra-abdominal viscera through a penetrating diaphragmatic injury.

Gunshot injuries of the head of the pancreas: conservative approach.

This study is comprised of 48 patients with gunshot injuries of the head of the pancreas, many of which were high velocity injuries. The purpose of this study was to evaluate our management policy for these injuries based on our recent wide experience. Patients with grade II and III injuries underwent conservative surgery, with 0% and 21% postoperative mortality, respectively, directly related to the pancreatic injury. For patients in whom the duodenum was involved, pyloric exclusion was applied depending on the grade of the duodenal injury. We concluded that moderate gunshot injuries of the head of the pancreas (grade II) can be safely treated by débridement and suture repair, with or without drainage. Severe (grade IV) injuries warrant a pancreaticoduodenectomy. Most grade III injuries can be treated by débridement and drainage unless an associated severe duodenal injury is present, in which case resection may be indicated.

Arterial gunshot injuries of the extremities: a South African experience.

This is a retrospective study of 173 patients with gunshot injuries of the major arteries of the extremities. A selective policy for the use of angiography was followed. The arterial repair was achieved by various means: primary end-to-end anastomosis, vein interposition graft, and polytetrafluoroethylene (Teflon) interposition grafts. Overall, there were nine amputations in the lower limb. Ninety-eight percent of the patients had a palpable pulse on discharge. There were 3 preoperative deaths, 1 intraoperative death, and 5 postoperative deaths (overall perioperative mortality, 3.5%). We conclude that the results of vascular extremity gunshot injuries are satisfactory when standard methods of management are used. Morbidity and mortality can be further reduced by prompt admission to appropriate centers.

Penetrating injuries of the popliteal artery: the Baragwanath experience.

This study describes the management of 43 patients with penetrating injury of the popliteal artery. Of these patients, 33 (76.5%) had bullet wounds, four patients (9.5%) pellet wounds and 6 (14%) knife wounds. Patients with 'hard' signs of arterial injury underwent exploration without preoperative angiograms. There were no negative explorations. Patients with only 'soft' signs of arterial injury underwent preoperative angiograms. Of this group, 75% had positive angiograms and underwent exploration. There were no false-positive or false-negative preoperative angiograms in the group of patients with 'soft' signs in this study. Definitive orthopaedic management of associated fractures followed vascular reconstruction. There was no difference in the short-term patency of autologous saphenous vein graft as against PTFE grafts. Fasciotomy was performed on patients who had arterial and venous injury or presented late. Overall amputation rate was 14% and for bullet injuries 18%.
