Review Case Reports
Management of acute hemorrhage due to cerebral AVM during pregnancy ---- case series and literature review.
Acute hemorrhage caused by cerebral arteriovenous malformation (cAVM) during pregnancy is uncommon but life-threatening for both mother and fetus and presents a great challenge to clinical management. However, there is still no consensus on the treatment strategy and the treatment timing of acute hemorrhage from cAVM during pregnancy. The aim of this study was to amalgamate reported case series and our cases regarding the clinical management of pregnant patients under this special condition. ⋯ A high rebleed rate and high mortality from rebleeding indicate that the intervention of ruptured cAVM should not be delayed. Intervention of ruptured cAVM within 2 weeks after initial hemorrhage is advisable in patients at gestational age <34 weeks, whereas termination of pregnancy as soon as possible followed by timely intervention of ruptured cAVM is practicable in patients at gestational age ≥34 weeks.

Few studies have evaluated the cost burden borne by neurosurgical patients in the developing world and their potential implications for efficient and effective delivery of care. This study aims to assess the cost associated with obtaining pediatric neurosurgical care in a hospital in Kaduna. ⋯ The mean cost of pediatric neurosurgical procedures in our setting is $895.99, which is 40.18% of our gross domestic product per capita. The main drivers of cost are the cost of operation, investigations, and intensive care unit length of stay.

Single-stage spinal correction without previous neurosurgical intervention has been attempted in patients with scoliosis associated with syringomyelia (SM). However, evidence to demonstrate its potential influence on associated SM from direct spinal correction is still lacking. The aim of the present study was to explore the role of spinal shortening in the prognosis of SM-associated scoliosis after single-stage spinal correction without previous neurosurgical intervention. ⋯ The reduction of spinal cord tension is an important factor influencing SM improvement. As the most powerful spinal-shortening osteotomy, PVCR can effectively correct severe spinal deformities and improve associated SM. Single-stage posterior spinal correction can be a potential choice for selected patients with scoliosis and untreated SM using strict inclusion criteria, which will not only achieve safe spinal correction but could also steadily improve and stabilize SM.

We sought to examine the conservative treatment of symptomatic spinal cavernomas and evaluate the efficacy and safety of surgical management of spinal cord cavernous malformations. ⋯ Patients who have experienced a hemorrhagic episode should consider surgical intervention, which decreases the risk of recurrent hemorrhage and further neurologic deterioration. In addition, surgical decompression obtained by resection of the hemorrhage and cavernoma seems to lead to slight neurologic improvement in some patients. In nonhemorrhagic cavernomas, conservative treatment might be optimal due to surgery-related morbidity risks.

The use of balloon guide catheters (BGCs) for proximal flow arrest during neurointerventional procedures has been limited owing to the incompatibility of BGCs with large-bore aspiration catheters and difficulty in device navigation. The objective of our study was to describe the use of the Walrus catheter (Q'Apel Medical, Fremont, California, USA), a new 8F BGC, with a variety of aspiration catheters and procedures requiring flow arrest. ⋯ Our results have demonstrated that the Walrus BGC is a highly navigable 8F guide catheter compatible with most available aspiration catheters. Owing to its compatibility with most available aspiration catheters and ease of use, the Walrus BGC is a valuable addition to the tools available for mechanical thrombectomy.
