Abstract:
OBJECTIVE/BACKGROUND: Carotid bifurcation resection with subsequent reconstruction is performed infrequently. While internal carotid artery (ICA) revascularisation is regarded as mandatory, the external carotid artery (ECA) is severed in most instances. Indications for and results of an autologous bifurcated carotid artery reconstruction are discussed. METHODS: This was a single centre retrospective analysis of a consecutive series of patients treated at an academic vascular surgery centre. RESULTS: From December 2006 to August 2015, 47 patients underwent reconstruction of the carotid artery using an autologous bifurcated interposition graft (36 men; median age 68.3 years [range 41-87 years]; 33 asymptomatic [70%]). The indication for reconstruction was recurrent carotid stenosis unfavorable for endovascular treatment/redo patch plasty (n = 29; symptomatic: n = 12), carotid aneurysm (n = 10), neck tumour with vascular involvement (n = 7), and trauma (n = 1). Groups were not different with regard to vascular risk factors. Non-reversed valve depleted saphenous/accessory saphenous vein from the groin was used in 44 (94%), and reversed valve depleted cubital vein bifurcation graft in three patients (6%). Median ICA cross clamp time was 17 min (range 8-30 min). Five patients suffered from intra-operative ischaemic neurological deficits (11%), of which all were temporary except one. One tumour patient died on post-operative day 1 due to bleeding. Median follow up was 28.3 months (range 0.1-97.4 months). Tumour erosion required graft ligation in one patient 7 months after reconstruction. Five significant stenoses of the ICA (11%), nine (19%) stenoses of the ECA, and two (4%) common carotid artery stenoses, with four (8%) re-redo interventions, were observed. Thirteen patients (28%) died after a median follow up of 6.7 months (range 1.7-56.7 months), all unrelated to the vascular procedure. CONCLUSION: Autologous bifurcated carotid artery interposition graft avoids the use of prosthetic graft material, the ECA remains patent in 80%, and it provides mid-term results comparable with other redo carotid artery procedures. Therefore, this procedure should be reserved for symptomatic patients with no other revascularisation option.
