PURPOSE: The purpose of this study is epidemiological analysis of patients with cerebral aneurysmis submited an embolization at Sao Jose Avaí Hospital.
METHODS: This coorte retrospective study analyses clinical and epidemiological variables.It was conducted from the database of patients submitted an ablation in the neurosurgery department of São José do Avaí Hospital in the period of Dec 2006 to Dec 2009.
RESULTS: We studied 1504 patients submitted to ablation. These 1120 were females (74,46%) and 384 males.The average age was 52 years. Hunt-Hess scale prevalence:1-67,88%, 2-18,62%, 3-8,19, 4-4,92%, 5-2,32%,and Fisher:1- 62,58%, 2-7,91%, 3-17,08%, 4-7,58%.The main risk factors involved into cerebral vascular accident were:Systemic arterial hypertension 40,4%(n=608)and smoking 30,8%(n=463). The arteries more involved were:posterior communicant=381(25,33%),median cerebral=296(19,61%) and anterior communicant=254(16,87%). 72,67% of patients presents only one aneurysm(n=1093)and 27,33% two or more aneurysms(n=411).Noticed the occurrence of 1217(80,91%) ruptured aneurysms and 287 incidental.The size of the aneurysms we had were: 46,30% standard aneurysms (between 5 and 25mm),47,95% smaller than 5mm and 5,75%giants.The aneurysms were narrow neck in 37,78% of the cases (n=1082), and large in 14,34% (n=412). Among the 218 events that occurred,there were coil into the vascular lumen in 96 cases(6,38%),bleeding in 58(3,85%) and others. The material used were:334 balloons and 136 stents. Angiographic vasospasm occurred in 178 patients.
CONCLUSION: Predominance of females for the occurrence of cerebral vascular aneurysmatic accident. The average age was 52years.Systemic hypertension and smoking showed strongly association with the rupture of intracranial aneurysms.The arteries of the previous segment were those that had higher incidence of aneurysms. More than half of the patients did not had complication during the procedure. Embolization of cerebral aneurysms revealed to be low lethality method.
CLINICAL IMPLICATIONS: The Cerebral aneurysms reach between 1 to 5% of adult population and are responsible for significant rates of morbility and mortality.The treatment of intracranial aneurysms evolved substantially endovascular neurosurgery.The ablation overtook a clipping as the initial method in many centers, including Brazil, because of the safety and feasibility of this method.
