Management of penetrating injuries of the upper extremities.

Background: Routine surgical exploration after penetrating upper extremity trauma (PUET) to exclude arterial injury leads to a large number of negative explorations and iatrogenic injuries. Selective non-operative management (SNOM) is gaining in favor for patients with PUET. The present study was undertaken to assess the validity of SNOM in PUET and to present a practical management algorithm.

Methods: All consecutive patients presenting to a tertiary referral center following PUET were included in this prospective observational cohort study. Patients were managed along Advanced Trauma Life Support (ATLS©) guidelines, and based on clinical manifestations, either underwent emergency surgery or were treated conservatively with or without additional diagnostic investigations. Computed tomography angiography (CTA) was indicated by a preset protocol based on the physical examination.

Results: During the four-month study period, 161 patients with PUET were admitted. Sixteen (9.9%) patients underwent emergency surgery, revealing 14 vascular injuries. Another 8 (5.0%) patients underwent vascular exploration following CTA. The remaining patients (n=137) were managed non-operatively for vascular matters. Eighteen (11.2%) patients required semi-elective surgical intervention for fractures or nerve injuries. During the follow- up, no missed vascular injuries were detected.

Conclusion: Neither routine exploration nor routine CTA is indicated after PUET. Stable patients should undergo additional investigation based on clinical findings only. SNOM is a feasible and safe strategy after PUET.
