Incidence of Vascular Complications Arising from Anterior Spinal Surgery in the Thoraco-Lumbar Spine
Abstrakt
tudy Design Modern biomaterials and instrumentation have popularised surgery of the thoraco-lumbar spine through an anterior route. The advantage of anterior surgery is that it allows for a direct decompression of the compromised spinal canal.
However, the potential for devastating long-term sequelae as a result of complications is high. Purpose The aim of this study was to give a general overview and identify the incidence of vascular complications.
Overview of Literature There is limited literature describing the overall incidence and complications of anterior spinal surgery. Methods A retrospective review of a prospective database of 1,262 consecutive patients with anterior surgery over a twelve-year period.
Results In our study, 1.58% (n=20) of patients suffered complications. Injury to a major vessel was encountered in 14 (1.11%) cases, of which nine involved an injury to the common iliac vein.
In six cases, the original procedure was abandoned due to a life-threatening vascular injury (n=3) and unfavourable anatomy (n=3). Conclusions The incidence of vascular and other complications in our study was relatively low.
Nevertheless, the potential for devastating long-term sequelae as a result of complications remains high. A thorough knowledge and awareness of normal and abnormal anatomy should be gained before attempting such a procedure, and a vascular surgical assistance especially should be readily accessible.
We believe use of access surgeons is mandatory in cases with difficult or aberrant anatomy.
