Results of surgical treatment of patients with internal carotid artery kinking depending on methods of its reconstruction

: It was analyzed the results of surgical treatment of 60 patients with internal carotid artery kinking operated in the department of vascular surgery of acad. B.V. Petrovsky Russian Scientific Center of Surgery of RAN. Indications for surgery included symptoms of cerebrovascular insufficiency (CVI) and instrumentally confirmed hemodynamically significant kinking of ICA. Criteria for surgical treatment were linear flow velocity gradient more than 2 and turbulent blood flow in the kinking segment diagnosed by ultrasonic scanning. All patients were divided into 2 groups depending on methods of surgery. The first group included 36 (60%) patients who underwent resection of ICA with orifice bringing down. The second group included 8 (13%) patients after ICA replacement and 16 (27%) cases with eversion endarterectomy, resection of ICA and orifice bringing down. The analysis of immediate surgery results did not reveal significant differences in dynamics of CVI and velocity parameters in reconstructed ICA (p>0.05). The index "stroke+mortality from stroke" was higher in the second group (p<0.05). Thrombosis of ICA reconstruction area has been developing more frequent (p<0.05) after ICA replacement (8%) in comparison with resection of ICA with orifice bringing down (0) and eversion endarterectomy, resection of ICA and orifice bringing down (0). Our data show that resection of ICA with orifice bringing down is preferable for surgical treatment of ICA kinking. ICA replacement is associated with significantly more frequent complications. Eversion endarterectomy with resection of ICA is optimal in case of combination of kinking with stenosis of ICA.
