Abstract:

Objective

Case data of carotid endarterectomy(CEA) were analyzed to obtain the characteristics of perioperative cerebrovascular events and associated risk factor.

Methods

We retrospected 209 cases of CEA in Beijing Tiantan Hospital from January 2012 to April 2015, and analyzed the clinical characteristics. Relevant factors of perioperative cerebrovascular events were tested by χ2 and the odds ratio (OR) was calculated.

Results

There were more males than females (177∶32). Cerebal infarction was the most common clinical manifestation (68.42%). Hypertension was the most common comorbidity (68.42%). There were 9 cases with hyperperfusion, 3 cases with cerebral hemorrhage in 5 cases with stroke during perioperative period. The proportion of hyperlipidemia in patients with hyperperfusion (8/9), chronic obstructive pulmonary disease (COPD) and chronic renal insufficiency (CRI) in patients with cerebral hemorrhage (2/3) were high. Univariate analysis by χ 2 test showed that hyperlipidemia was a risk factor for perioperative cerebrovascular events (OR=3.861, P=0.029). Besides concomitant hyperlipidemia was a risk factor for perioperative hyperperfusion (OR=17.397, P=0.001).The presence of chronic obstructive pulmonary disease in patients was a risk factor for perioperative stroke (OR=33.333, P=0.007), and also a risk factor for perioperative intracerebral hemorrhage(OR=101.000, P=0.002)., Chronic renal insufficiency was a risk factor for perioperative intracerebral hemorrhage (OR=51.000, P=0.043).

Conclusion

Hyperperfusion was the most common cerebrovascular events during perioperative period of CEA, and cerebral hemorrhage was the most serious cerebrovascular events. Hyperlipidemia increased the risk of hyperperfusion.Patients with COPD and CRI had a higher risk of perioperative cerebral hemorrhage.
