Background. The authors report their experience of internal carotid artery (ICA) replantation.
Methods. Between 1990 and 1997 a total of 412 patients underwent carotid surgery. In 33 cases carotid surgery was associated with another operation. In this series 42 patients (11.9%) underwent ICA replantation. 14 patients revealed symptomatic kinking, 9 of which were operated bilaterally; 19 presented marked tortuosity of the ICA associated with hemodynamically significant and/or symptomatic stenosis affecting the same artery. The aim of this study was to illustrate the replantation technique used and the medium-term results (follow-up of 1-65 months, mean follow-up 35.5 months). The scope of surgery was to eliminate the elongation causing the underlying dysmorphia, as well as treating any associated lesions. The technique used can be divided into two basic stages:
— exposure and freeing of dysmorphia;
— transverse resection of ACI, eversion TEA, longitudinal arteriectomy of the common carotid artery, TEA of the latter, end-to-end anastomosis of the ICA and common carotid artery. A total of 35 patients (83.3%) were followed up.
Results. Three patients died (7%). One patient died 4 months later for reasons directly linked to surgery, due to the consequences of cerebral hemorrhage which occurred eight hours after the operation (2.38%); two died from other causes (AMI in both cases after 24 and 30 months of follow-up) (4.76%). The remaining 32 patients were controlled as outpatients and underwent colour Doppler sonography (32 out of 32) and angiography (18 patients, 42.8%).
Conclusions. Good patency was observed in all replantations with no residual functional deficits.
