The American Association for the Surgery of Trauma PROspective Observational Vascular Injury Treatment (PROOVIT) registry: Multicenter data on modern vascular injury diagnosis, management, and outcomes

BACKGROUND: There is a need for a prospective registry designed to capture trauma-specific, in-hospital, and long-term outcomes related to vascular injury. METHODS: The American Association for the Surgery of Trauma PROspective Vascular Injury Treatment (PROOVIT) registry was used to collect demographic, diagnostic, treatment, and outcome data on vascular injuries. RESULTS: A total of 542 injuries from 14 centers (13 American College of Surgeons-verified Level I and 1 American College of Surgeons-verified Level II) have been captured since February 2013. The majority of patients are male (70.5%), with an Injury Severity Score (ISS) of 15 or greater among 32.1%. Penetrating mechanisms account for 36.5%. Arterial injuries to the head/neck (26.7%), thorax (10.4%), abdomen/pelvis (7.8%), upper extremity (18.4%), and lower extremity (26.0%) were identified, along with 98 major venous injuries. Hard signs of vascular injury, including hypotension (systolic blood pressure <90 mm Hg, 11.8%), were noted in 28.6%. Prehospital tourniquet use for extremity injuries occurred in 20.2% (47 of 233). Diagnostic modalities included exploration (28.8%), computed tomographic angiography (38.9%), duplex ultrasound (3.1%), and angiography (10.7%). Arterial injuries included transection (24.3%), occlusion (17.3%), partial transection/flow limiting defect (24.5%), pseudoaneurysm (9.0%), and other injuries including intimal defects (22.7%). Nonoperative management was undertaken in 276 (50.9%), with failure in 4.0%. Definitive endovascular and open repair were used in 40 (7.4%) and 126 (23.2%) patients, respectively. Damage-control maneuvers were used in 57 (10.5%), including ligation (31, 5.7%) and shunting (14, 2.6%). Reintervention of initial repair was required in 42 (7.7%). Amputation was performed in 7.7% of extremity vascular injuries, and overall hospital mortality was 12.7%. Follow-up ranging from 1 month to 7 months is available for 48 patients via a variety of modalities, with reintervention required in 1 patient. CONCLUSION: The PROOVIT registry provides a contemporary picture of the management of vascular injury. This resource promises to provide needed information required to answer questions about optimal diagnosis and management of these patients-including much needed long-term outcome data.
