Anti-coagulation management in pediatric traumatic vascular injuries.

Background: Pediatric traumatic vascular injuries are rare. Given the paucity of data to guide anti-coagulation (AC) management of these injuries in children, who have a lower overall risk for thrombosis compared to their adult counterparts, we sought to examine and summarize our recent experience.
Method: We conducted a retrospective review of all patients (<18 years old) who sustained traumatic vascular injuries between 2010-2018 at a Level 1 and Level 2 Pediatric Trauma Center.
Results: Ninety-nine patients had traumatic vascular injuries. Eighty-four patients sustained a major arterial injury, 26 had a major venous injury, and 11 had both arterial and venous injuries. The arterial injury cohort had a median age of 13.3 years. Most of the arterial injury patients (65/84, 77%) required vascular repair. In-hospital AC management for the arterial injury patients consisted of a post-operative heparin drip (18%, 15/84), aspirin (39%, 26/84), enoxaparin (23%, 19/84), or none (42%, 43/84). Approximately one-half of the patients with arterial injuries (54%, 45/84) were discharged home on AC therapy, most commonly aspirin. Fifty-six patients (66%) followed up post-injury, of which 25% (14/56) had experienced complications.
Conclusion: Pediatric traumatic arterial injuries that require surgical intervention other than ligation should be considered for discharge AC - most commonly aspirin - in the absence of contraindications. Pediatric patients with vascular injuries to the aorta, carotid artery, inferior vena cava, portal vein, or lower extremities that are managed non-operatively should also be considered for AC. The preferred AC for pediatric venous injuries is enoxaparin, in the absence of contraindications.
