RESUMEN
Objective To identify the risk factors of delayed cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH). Methods The clinical data of 74 patients with SAH were retrospectively analyzed. The severity of delayed cerebral vasospasm in these patients was assessed according to the findings by digital subtraction angiography, and the risk factors for delayed cerebral vasospasm following SAH were analyzed. Results The patients' age, number of SAH episode, histor yof smoking, Hunt-Hess grade, Fisher grade and peak white blood cell count were found to significantl ycorrelated to the occurrence of delayed cerebral vasospasm. Among these factors, the patients' age, number of SAH, Hunt-Hess grade, and Fisher grade were identified as the independent risk factors of delayed cerebral vasospasm. Conclusions Patients with younger age, SAH more than twice, and Hunt-Hess or Fisher grades over Ⅲ are at higher risk of delayed cerebral vasospasm. Close monitoring fo rearly detection of delayed cerebral vasospasm and timely management are crucial in these patients.
RESUMEN
Objective To analyze the effect of NexusTM coils for endovascular occlusion of intracranial aneurysms. Methods In 41 patients with intracranial aneurysms, endovascular occlusion of 43 aneurysms was performed using NexusTM coils. The follow-up data of the patients for 6 to 12 months were reviewed, and the imaging data from digital subtraction angiography (DSA), CT angiography (CTA) or magnetic resonance arthrography (MRA) alter the treatment were analyzed. Results In the 41 patients, 1 died, 1 had aneurysm recurrence, 3 had cerebral infarction, 1 showed ocular paralysis, and 2 developed hydrocephalus after the surgery. Evaluation with modified Rankin Scale showed grade 0 in 8 cases, grade 1 in 19 cases, grade 2 in 7 cases, grade 3 in 3 cases, grade 4 in 1 case, grade 5 in 1 ease and grade 6 in 1 case. Conclusion Endovascular embolization with NexusTM coils is effective for treatment of intracranial aneurysms especially in cases of small aneurysms and parent artery occlusion. Caution should be taken with the coil for endovascular occlusion of the neck of anterior and middle cerebral artery aneurysms with thin parent arteries, as the fibers in the coil may cause thrombosis and potential cerebral infarction.
