Title: Carotid surgery under cervical block anesthesia. A simple method of heart and brain protection in high risk patients. Author: Bergeron P, Benichou H, Dupont M, Mery A, Boldrini A, Alessandri C, Varlet P, Jausseran JM, Reggi M, Rudondy P. Journal: Int Angiol; 1989; 8(2):70-80. PubMed ID: 2809334. Abstract: Between January 1, 1985, and December 15, 1987, 60 patients underwent surgery for carotid lesions under local cervical block anesthesia. Sixty-seven reconstruction procedures were performed including 64 endarterectomies and 3 vein bypasses. During the same 3 year period, 938 other reconstruction procedures were carried out under general anesthesia for a total of 1005 procedures. These 60 patients, who accounted for 6.7% of our indications, were selected for surgery under local anesthesia because they were at high risk for cardiac and neurologic complications. As far as staging is concerned, this subgroup of patients included: 14 asymptomatic cases (stage 0), i.e., 21%; 44 transient ischemic attacks (stage I), i.e., 66%; 2 progressive stroke (stage II), i.e., 3%; 7 patients with neurologic sequels (stage III), i.e., 10%. In all 79% of the patients were symptomatic. The asymptomatic patients all presented bilateral tight stenosis sometimes with thrombosis of the contralateral carotid. The technique of local anesthesia and endarterectomy were classic: closing with a bougie to calibrate the lumen, systematic intraoperative arteriography and immediate correction of technical failures (2 times); no death occurred among the patients in stages 0, 1 and II; 1 early asymptomatic occlusion that was not corrected was noted; in one case, a ligation of the carotid was necessary after technical failure, without consequences; one death occurred in stage III after intracerebral hemorrhage. On the basis of our experience local cervical block anesthesia appears to be a simple and reliable method of ensuring intraoperative diagnosis of cerebral ischemia. It eliminates all intraoperative cerebral complications secondary to ischemia and allows a better understanding of the physiopathologic mechanisms underlying perioperative neurologic complications. The absence of neurologic and cardiac complications in this series of very high risk patients enables us to extend eligibility for surgery to include patients with unstable cardiac and cerebral disease.[Abstract] [Full Text] [Related] [New Search]
