Aortic rupture is a rare but possible complication during spine surgery. It may manifest as severe intraoperative hemorrhage or present in a delayed manner after the formation of an aneurysm or an arteriovenous fistula. Though it is commonly encountered during anterior surgeries involving the surgical field close to the thoracic or abdominal aorta, it can also occur during a posterior surgery. Aortic injury could be associated with surgeries ranging from the commonly performed pedicle screw instrumentation to a complex three-column osteotomy. It can also occur, as in the reported case, while performing complex procedures in the presence of a pre-existing aneurysm or aortic adhesions due to coexisting infectious or inflammatory pathologies. The treatment options for such aortic ruptures range from open repair to endovascular stenting techniques. We discuss a case of an aortic rupture that occurred during a posterior vertebral column resection (PVCR) procedure performed on a 58-year-old female with spastic paraparesis secondary to tuberculous spondylodiscitis and the lessons learnt.
