Carotid rupture and tissue coverage.

Abstract

Carotid rupture following the treatment of head and neck malignancy is the most dreaded complication faced by the head and neck surgeon. Tissue coverage of the carotid artery has been advocated as the method of protection likely to prevent carotid rupture. A retrospective study was carried out to assess the benefit of carotid coverage and whether such protection plays a role in decreasing mortality and morbidity. A brief history of carotid protection is presented. A series of 194 head and neck cancer patients who underwent resection of their mucosal primary in continuity with radical neck dissection over a ten-year period was reviewed. No coverage was used in 120 cases, while 72 cases received carotid coverage. There was a 13% fistula rate and a 15% rate of wound complication without fistula. Six patients without recurrence who had carotid rupture or ligation for imminent rupture were identified. This group was scrutinized with regard to several parameters. Three received tissue coverage of the carotid system, while the other three were left unprotected. There was 50% mortality rate and 25% rate of neurologic sequelae amongst the survivors. This review tends not to support the premise that tissue coverage is a major factor in the prevention of carotid rupture.
