Interventional treatment with stent graft implantation of pseudoaneurysm following blunt dissection of carotid body tumors

Abstract

Abstract: PURPOSE: To evaluate the clinical effect of surgical treatment of carotid body tumor and interventional treatment with stent graft implantation of pseudoaneurysms following blunt dissection of the tumor treated. METHODS: Six cases were classified as Shamblin I, II and III in 1, 1, and 4 cases, respectively. The tumor sizes varied from a minimum of 2 cm×3 cm to a maximum of 5 cm× 6 cm (median: 3.7 cm×4.7 cm). Two of them underwent blunt dissection of carotid body tumor, two underwent blunt dissection and ligation of external carotid artery of carotid body tumor and 2 had common carotid artery-internal carotid artery artificial vascular reconstruction. RESULTS: No perioperative mortality and stroke occurred. The range of mean blood loss was 455 mL (range, 250-650 mL). Two patients had pseudoaneurysm or vocal cord paralysis postoperatively and both recovered with stent graft implantation and medical treatment respectively. The patients were followed up for 6-17 months, no recurrence was seen at the follow-up period. CONCLUSIONS: Surgical treatment of carotid body tumor is acceptably safe and effective according Shamblin classification; Pseudoaneurysms following blunt dissection of the tumor can occur and using a stent graft was feasible for treating the lesion.
