ABSTRACT
Objective To investigate the relation between the balloon occlusion test ( BOT) and the anatomy of the circle of Willis ( CW) , and to explore the role of balloon occlusion test in the treatment of internal carotid artery permanent occlusion. Methods Selected the clinical data of 49 patients (52 sides) who had BOT in our hospital from October 2009 to June 2015,and analyzed the relationship be-tween the occurrence rate of anterior communicating artery ( AcoA) / posterior communicating artery ( PcoA) and the positive rate of BOT retrospectively. Results The occurrence rate of the AcoA was 97. 9%, and the occurrence rate of PcoA in one side was 82. 7%. Negative rate BOT accounted for 92. 3% and AcoA occurred in all, while the positive rate accounted for 7. 7%, including 2 cases of right superior ar-teria cerebri anterior combined with ipsilateral PcoAs absence, 1 case of left superior arteria cerebri anterior combined with ipsilateral PcoAs absence, and 1 case of AcoA and PcoAs absence. Conclusion Before the permanent occlusion of the internal carotid artery, it’ s necessary to clarify the redistribution of the compensatory way of blood flow in the AcoA-absent cases. Implementing permanent occlusion for cases with complete circle of Willis would cause less ischemic risk.
ABSTRACT
Objective To discuss the importance of balloon occlusion test before interventional treatment of the intracranial giant intemal carotid artery aneurysms and to sum up the nursing experience in assisting the procedure. Methods Proper perioperative nursing measures were carried out for 12 patients, who suffered from intracranial giant internal carotid artery aneurysm and underwent spring coil occlusion treatment. Nursing measures included mental care, observation of the vital signs, prevention of the complications, etc. Results Neither death nor exacerbation of the condition occurred in all the 12 patients. The patients were discharged from the hospital with a mean hospitalization of nine days. During a follow-up period ranged from 4 months to one year, seven patients had no disagreeable feeling, one patient complained of discomfort but no abnormality was found on follow-up DSA, and disappearance of the aneurysm was observed in 4 patients. Conclusion The monitoring of the vital signs, the prevention of the complications and the standard nursing care are the key points for ensuring a successful operation in treating intracranial giant intemal carotid artery aneurysms with spring coil occlusion.
