Carotid endarterectomy (CEA) is a surgical procedure performed to restore carotid blood flow and reduce the incidence of embolic and thrombotic strokes. Although it is a preventive procedure, CEA carries the risk of perioperative complications: neurologic and cardiac. Major complications of CEA are intra and postoperative stroke, myocardial infarction, and death. To reduce the number of intraoperative stroke events, one of them is to develop intraoperative monitoring technology with electroencephalogram (EEG). In this case, a male patient, 62 years old, with statistics of recurrent stroke and left leg weakness was approved for CEA under general anesthesia. Surgeons decide to use shunt selectively by assessing EEG monitoring when clamping. Finally the shunt was not performed, the operation lasted for 6 hours, tinged with hemodynamic shocks that often occur in patients with carotid disease due to baroreceptor disorders. By managing anesthesia meticulously during and after surgery, the operation was successfully performed, and the results of the post on the left leg strengthening motor increased from 2 to 4.

Abstract The importance of cerebral ischemia produced by carotid clamping during carotid endarterectomy remains controversial. In an effort to determine the importance of cerebral ischemia during carotid endarterectomy. 369 patients undergoing 431 consecutive carotid endarterectomies were studied by Xenon-133 (133Xe) clearance and electroencephalogram (EEG) monitoring. None of the patients was shunted during the procedures. The severity of ischemia as indicated by 133 Xe clearance from the ipsilateral hemisphere during 20 to 30 minutes of carotid occlusion did not predict the appearance of complications in this group of patients (x2 = 1.417: P = 0.841). There was a highly significant relationship between the depth of cerebral ischemia as demonstrated by 133Xe clearance and the appearance of abnormalities on the EEG (x2 = 42.043, P < 0.0001). In the subgroup of patients developing abnormalities as shown by EEG. there was a negative correlation (x2 = 17.495; P < 0.002) between reduction in blood flow and the appearance of complications, in that the higher the blood flow during occlusion the more likely the patient developing EEG changes would develop complications.

Background: Cross-clamp ischemia during carotid endarterectomy (CEA) can cause perioperative stroke. Selectively shunting patients based on intraoperative monitoring modalities that assess risk for ischemia can reduce the occurrence of immediate stroke. An experience with combined cerebral oximetry and stump pressure measurement to direct selective shunting is presented here. Methods: Study comparing intraoperative monitoring data, the decision to shunt, and presence of immediate post-operative deficits. Patients were shunted if either cerebral oxygen saturation dropped by more than 10% by cerebral oximetry, or stump pressure during cross-clamping was less than 40 mmHg. Cross-clamp ischemia was determined by the presence of ipsilateral neurological deficit upon awakening. Results: 245 patients were included in this study. 22% were shunted. Patients who were not shunted were significantly more likely to have collateral blood flow detected on angiography. Immediate post-operative stroke was not encountered in any of the patients included in the study. One patient who met shunting criteria but was excluded since he could not have a shunt inserted due to difficult anatomy did suffer stroke. Conclusions: With the dual-monitoring criteria presented here, 22% of patients were shunted. With the exception of one patient who could not have a shunt placed, no immediate post-operative stroke was encountered.

✓ Ninety-three endarterectomies for carotid stenosis were monitored with cerebral blood flow (CBF) measurements, and 113 with both CBF measurements and a continuous electroencephalogram (EEG). Significant CBF increase occurred only when carotid endarterectomy was for a stenosis greater than 90%. A high correlation between CBF and EEG indicated when a shunt was required. To sustain a normal EEG, the CBF ascertained by the initial slope technique must be 18 ml/100 gm/min at an arterial carbon dioxide tension (PaCO2) of 40 torr. The degree of EEG change below this level during occlusion reflected the severity of reduced blood flow and was reversible with replacement of a shunt. The value and limitations of these monitoring techniques and a concept of ischemic tolerance and critical CBF are discussed.

Background: In the present study the perioperative complication rate is compared between high- and low-risk patients when carotid endarterectomy (CEA) is routinely performed under local anaesthesia (LA). Patients and methods: From January 2000 through June 2008 1220 consecutive patients underwent CEA under LA. High-risk patients fulfilled at least one of the following characteristics: ASA 4 classification, “hostile neck”, recurrent ICA stenosis, contralateral ICA occlusion, age ≥ 80 years. The combined complication rate comprised any new neurological deficit (TIA or stroke), myocardial infarction or death within 30 days after CEA, which was compared between patient groups. Results: Overall 309 patients (25%) were attributed to the high-risk group, which differed significantly regarding sex distribution (more males: 70% vs. 63%, p = 0,011), neurological presentation (more asymptomatic: 72% vs. 62%, p = 0,001) and shunt necessity (33% vs. 14%, p < 0,001). In 32 patients 17 TIAs and 15 strokes were observed. In 3 patients a myocardial infarction occurred. Death occurred in one patient following a stroke and in another patient following myocardial infarction, leading to a combined complication rate of 2,9% (35/1220). In the multivariate analysis only previous neurological symptomatology (OR 2,85, 95% CI 1,38-5,91) and intraoperative shunting (OR 5,57, 95% CI 2,69-11,55) were identified as independent risk factors for an increased combined complication rate. Conclusions: With the routine use of LA, CEA was not associated with worse outcome in high-risk patients. Considering the data reported in the literature, it does not appear justified to refer high-risk patients principally to carotid angioplasty and stenting (CAS) when LA can be chosen to perform CEA.
