The PROspective Observational Vascular Injury Trial (PROOVIT)

Обзор

Evidence suggests that the rate of treatable vascular injury is increasing due to improved pre-hospital strategies. The increased rate of vascular trauma occurs in an era of increased sub-specialization, shifting training paradigms and the emergence of endovascular therapies. These factors, in combination with the baseline complexity of vascular trauma, make it particularly important that the management of this injury pattern be evidence-based. However, because all forms and distributions of vascular injury represent only 4% to 9% of trauma admissions, meaningful study of one injury pattern, patient population, therapeutic or surveillance strategy is difficult at a single institution. Further complicating such efforts is the fact that vascular trauma is managed by a wide range of surgical and now endovascular specialists, further fragmenting even a busy trauma institution's experience with vascular injury.

Подробное описание

Several institutions and groups have contributed important insight into the understanding of vascular injury management. However, many of the studies have been single-institution, poorly powered and retrospective. The lack of evidence-based practice is even more concerning given the devastating consequences associated with mismanaged vascular trauma. In light of the stated challenges associated with single-institution study of this injury pattern, the logical method with which to proceed is a prospective, multicenter, observational trail. To date no such registries exists which would allow the prospective aggregation of larger amounts of data pertaining to all phases of vascular trauma management.

Contemporary experience confirms that the management of vascular injury is more complicated than in the past. A multitude of new or updated diagnostic technologies including computed tomography angiography (CTA), magnetic resonance angiography (MRA), duplex and arteriography now exist and are in various degrees of vogue. A damage control approach to vascular trauma is widely championed and includes options for the use of tourniquets, temporary vascular shunts and fasciotomies. Controversies regarding the definitive management of vascular trauma abound and include the advisability of open versus endovascular treatment, decisions about the type of vascular conduit and the utility of venous injury repair lo list a few. Recommendations for surveillance after vascular trauma may include the use of duplex ultrasound or CTA to confirm long-term patency as well as choices related to the use of long-term anti-thrombotic therapy. Finally, it is not uncommon for an institution to find itself facing many of these decision points in the most challenging of all scenarios, the extremes of age including pediatric vascular injury.

• Процедура Vascular Injury
  The Society of Vascular Surgery has established a robust vascular disease registry but this organization's focus is on vascular disease and lacks capture of the data points necessary to discern trauma-specific outcomes. Recent military experience from the United States and United Kingdom, including the Balad Vascular Registry and the Global War on Terror (GWOT) Vascular Registry have provided a contemporary assessment of wartime vascular injury, but again these studies have been retrospective ca
