Iatrogenic arterial injuries of spine and orthopedic operations.

Objective: To describe the results of contemporary management of iatrogenic arterial injuries following spine and orthopedic operations.

Methods: Patients with major arterial injuries following spine and orthopedic operations in four teaching hospitals (Henry Ford Hospital, Detroit, Mich; Henry Ford Macomb Hospital, Clinton Township, Mich; St John Macomb Hospital, Warren, Mich; and St John Hospital, Detroit, Mich) over the last 10 years were studied. Data were collected on a continuous basis from vascular registries and analyzed retrospectively.

Results: Seventeen patients (8 spine, 9 orthopedic operations) had iatrogenic arterial injuries manifest as thrombosis or laceration with bleeding, pseudoaneurysm, or arteriovenous fistula. The majority of arterial lacerations with bleeding and pseudoaneurysms were treated with open surgical repair while the majority of thromboses and arteriovenous fistulae were treated with endovascular techniques. Fasciotomy was necessary in three of seven patients with arterial complications of knee and hip operations. There was no mortality or limb loss. Significant morbidity in the form of foot drop (1), iliac vein thrombosis (2), delayed ambulation due to hematoma and swelling of the lower extremity (2), and ischemic myonecrosis of calf muscles (1) occurred. Two patients launched legal action.

Conclusion: Arterial injuries following orthopedic and spine operations can be successfully managed by both open and endovascular techniques. Significant morbidity and increased length of stay is common. Patient dissatisfaction with the complication and need for ensuing treatment can have significant medicolegal consequences.
