An observational study of 256 cases of vascular trauma in the north western province of Pakistan.
During the past 10 years Peshawar has dealt with increasing casualties with penetrating trauma inflicted by a wide variety of missiles. The aim of this study was to assess whether delay in arrival and mode of presentation affects the outcome of patients with penetrating vascular trauma. Prospective data were collected on 256 vascular injuries in 248 patients (median age, 29 years; range, 7-60 years) between January 1995 and June 1998. Early presentation (group A, 55 cases, < 12 h) was compared with late presentation (group B, 201 cases, > 12 h). The majority of injuries (93%) were caused by fire-arms. Arterial injuries accounted for 71% of the total, venous injuries accounted for 10% and 19% were mixed. The site of injury was the lower limb (61%), upper limb (32%), abdominal cavity (5%) and neck (2%). Patients presented with absent pulses (56%), haemorrhage (46%), false aneurysms (8%), A-V fistula (5%) and 11% presented with more than one sign. There were significantly more lower limb amputations in group A than group B (23% versus 5%; P < 0.05), with fractures having a positive association with lower limb amputations (odds ratio, 0.32; 95% CI, 0.13-0.94; P < 0.05). Group A had a higher mortality than group B (18% versus 7%; P < 0.05). This study shows that patients with vascular trauma can be managed successfully with clinical assessment alone. Patients with fractures were more likely to suffer eventually from lower limb loss. Due to self-selection, arrival at the hospital less than 12 h after sustaining vascular injury was associated with a higher mortality than those presenting after 12 h.
