Endovascular therapy can offer faster, easier access to the extremity vascular injury facilitating revascularization and avoiding long incisions and dissections.
Background
Rates of major venous injury are now being reported at between
1% and 15%. Risk factors for injury include the previous
spine surgery, level of exposure, and number of retractors used. To review
and describe the evolution of our use of stent grafts for repair of
life-threatening ilio-caval injuries encountered during anterior exposure
lumbosacral (L-S) spine surgery from rescue utilization after failed direct
repair to preferred modality using occlusion balloons and covered stents
akin to the modern management of the ruptured abdominal aortic aneurysm
(AAA) with endovascular aneurysm repair.
Methods
Five-year retrospective review of all anterior and retroperitoneal
spine procedures was performed at our institution.
Results
One hundred two procedures were done. Major ilio-caval injury
occurred in 3/102 (2.9%) cases. Average blood loss per case
decreased as our approach evolved from unsuccessful direct open repair with
percutaneous endovascular rescue to primary percutaneous endovascular
repair. All treated patients had patent venous repair in short-term
follow-up with computed tomography angiography.
Conclusions
Identification and rapid direct repair of major ilio-caval injuries
during anterior approach spine surgery can be extremely challenging. When
control of these potentially fatal injuries is required, our choice is
primary endovascular repair using the modern techniques for endovascular
management of ruptured AAA with endovascular aneurysm repair.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
