摘要:
OBJECTIVE:Colloid cysts of the third and lateral ventricles have traditionally been treated by transfrontal and transcallosal microsurgical resection or by stereotactic aspiration. Recently, rigid and flexible ventricular endoscopic techniques have been used to treat these lesions. Our study was undertaken to examine the efficacy of rigid endoscopy in the resection of colloid cysts.METHODS:Fifteen patients with a radiological diagnosis of colloid cysts were given the option of undergoing either endoscopic surgery or craniotomy. The average tumor size was 1.43 cm. Fourteen patients underwent planned endoscopic resections, and a craniotomy was performed initially in one patient.RESULTS:Entire tumor resection was achieved with the endoscope in 12 patients (86%). A craniotomy was required for two colloid cysts that could not be resected endoscopically. In total, complete radiographic resections were achieved in 14 patients (93%). There were no permanent complications, although postoperative deficits included short-term memory loss and hemiparesis, each in one patient.CONCLUSION:Rigid endoscopy affords good optical resolution, high magnification, and excellent illumination. Total or near total resection of colloid cysts should be the goal for all patients and can be achieved using the rigid endoscope, with little morbidity, shortened operative time, reduced length of stay, and resolution of symptoms. Although long-term follow-up is needed, we think that endoscopy should be considered as a primary treatment for most patients.

摘要:
OBJECTIVE AND IMPORTANCE:After developing subarachanoid hemorrhage, patients may deteriorate from a variety of well-known causes, including rebleeding, hydrocephalus, and vasospasm. Many patients now undergo empirical hyperdynamic vasospasm therapy with hypervolemia, induced hypertension, and nimodipine.CLINICAL PRESENTATION:We report two cases of iatrogenic hypertensive encephalopathy occurring during hyperdynamic therapy for cerebral vasospasm after subarachnoid hemorrhage. Hypertensive encephalopathy is a syndrome of rapidly evolving generalized or focal cerebral symptoms occurring in the setting of severe hypertension, which is reversible with antihypertensive therapy.INTERVENTION:The syndrome can be diagnosed in the appropriate clinical setting with computed tomographic or magnetic resonance imaging that demonstrates characteristics findings. In both cases, decreasing the blood pressure resulted in neurological improvement.CONCLUSION:In the setting of induced hypertensive/hypervolemic therapy for vasospasm, hypertensive encephalopathy should be considered as a potentially reversible cause of delayed neurological decline.

摘要:
OBJECTIVE AND IMPORTANCE:Recanalization and subsequent rupture of giant aneurysms of the posterior circulation after Hunterian ligation is an extremely rare event that has been noted to occur with basilar apex, basilar trunk, and vertebrobasilar junction aneurysms. We report the case of a giant, previously unruptured right vertebral artery aneurysm, which recanalized from the contralateral vertebral artery and subsequently ruptured after previously performed angiography showed complete thrombosis of the aneurysm.CLINICAL PRESENTATION:A 72-year-old woman presented with headaches, ataxia, and lower extremity weakness. A giant 3-cm right vertebral artery aneurysm was found during the patient evaluation.INTERVENTION:Because of the size of the aneurysm and the absence of a discrete neck, Hunterian ligation was performed. After treatment, angiograms showed no filling of the aneurysm from either the right or left vertebral artery. Nine days later, after the patient developed lethargy and nausea, repeat angiography showed that a small portion of the aneurysmal base had recanalized. The next day, the patient had a massive subarachnoid hemorrhage and subsequently died.CONCLUSION:We think that this is a previously undescribed complication associated with direct arterial ligation of giant vertebral artery aneurysms. Patients with aneurysms treated using Hunterian ligation need to be followed up closely. Even aneurysms that have minimal recanalization are at risk for subarachnoid hemorrhage.
