Salvage operations of free tissue transfer following internal jugular venous thrombosis: a review of 4 cases.

Abstract

The internal jugular vein (IJV) is used as the optimal recipient for free-tissue transfer in reconstruction following modified radical neck dissection. Some reports documented rare cases of flap compromise following IJV thrombosis, but large sample studies are few. We present cases of emergent exploration and an analysis of factors to improve salvage rates of compromise due to IJV thrombosis. From a survey of 756 patients, four developed congestion due to IJV thrombosis and returned to the operating room. A restrospective analysis was made from the case records. This represents a rate of 0.5% for the entire series. Three flaps survived,and one failed. Detection of compromise ranged from 7-25 h postoperatively. All four IJVs recovered to provide adequate drainage after thrombectomy. While flap compromise following IJV thrombosis is rare, careful observation and early exploration are crucial for salvage, as in other microvascular venous crises.
