RESUMO
Objective To investigate the clinical efficacy of carotid endarterectomy ( CEA) for the treatment of patients with dolichoarteriopathies of internal carotid artery combined with carotid artery severe stenosis. Methods From January 2013 to February 2018,the clinical data of 18 consecutive patients with dolichoarteriopathy of internal carotid artery combined with carotid artery severe stenosis admitted to the Department of Neurosurgery,the First Affiliated Hospital of Soochow University were analyzed retrospectively. All patients underwent color Doppler ultrasound,CT angiography (CTA),and DSA to assess the diseased vessels before operation,and blood perfusion of the cerebral hemisphere was evaluated by CT perfusion (CTP) imaging. Six patients of Metz grade Ⅱ and 4 of grade Ⅲ underwent valgus CEA +excision of the redundant internal carotid arteries;8 patients of Metz grade I were treated with standard CEA. Postoperative cervical vascular ultrasound,CTA,and CTP examinations were performed in order to understand the vascular patency of the surgery and correction of dolichoarteriopathies of internal carotid artery. The follow-up time was 6 to 72 months. The color Doppler flow imaging and CTA were used to assess the presence or absence of restenosis and MRI was used to evaluate the presence of new cerebral infarction. Results All 18 patients were successfully operated, and they had good vascular patency after operation. The Postoperative CTA showed that the distorted blood vessels had been straightened to varying degrees for ten patients who underwent valgus CEA treatment and the plaques were removed satisfactorily without stenosis for 8 patients treated with standard CEA. After operation,one patient developed sublingual nerve injury symptoms,which was improved after 3 months. One patient developed mild hyperperfusion syndrome,which was improved after 2 weeks. No patients died. Follow-up reexamination showed that all patients had no carotid artery restenosis and new stroke events. Conclusions CEA is a safe and effective treatment for patients with internal carotid artery dolichoarteriopathy combined with severe carotid stenosis. According to the characteristics of the lesions evaluated before surgery, surgical methods should be selected reasonably.
RESUMO
Objective To investigate the surgical efficacy for the treatment of ruptured anterior communicating artery aneurysms with different dome projections in acute phase via supraorbital lateral approach.Methods From January 2014 to March 2017,the clinical data of 79 patients with acute ruptured anterior communicating artery aneurysm with different dome projections in acute phase treated via supraorbital lateral approach in the First Affiliated Hospital of Soochow University were retrospectively analyzed.The operative efficacy was analyzed.The Glasgow outcome scale (GOS) score was used to evaluate the prognosis at 3-36 months after procedure.Results In the 79 patients,34 were superior dome projections,37 was inferior dome projections,and 8 were complicated dome projections.All the anterior communicating artery aneurysms were successfully clipped.The patients were followed up for 3-36 months after procedure.GOS showed good prognosis in 70 cases (88.6％),of which 26 were superior dome projections,36 were inferior dome projections,and 8 were complicated dome projections;9 suffered mild disability (11.4％),of which 8 were superior dome projections and 1 was inferior dome projection.There were no severe disability,persistent vegetative state,and death.The prognosis in patients with inferior dome projection was better than that of superior dome projection (97.3％ [36/37] vs.76.5％ [26/34]).The difference was statistically significant (χ2=5.19,P<0.05).Conclusions The lateral supraorbital approach is an effective option for treating ruptured ACoAA with different dome projections in acute phase.The prognosis in patients with inferior dome projection is better than that of superior dome projection.
