PURPOSE: Subarachnoid hemorrhage (SAH) is a rare but life-threatening clinical event for pediatric patients. Cerebral vasospasm is a common complication of SAH that often leads to poor outcomes. This case report describes the use of dual intraventricular (IVT) vasodilators in a pediatric patient. SUMMARY: An 11-year-old male presented with traumatic diffuse SAH and cranial vasospasm. Despite treatment with IVT nicardipine, intravenous (IV) milrinone by continuous infusion, enteral nimodipine, and intraarterial verapamil and milrinone given during digital subtraction angiography, transcranial Doppler (TCD) mean velocities continued to rise. IVT milrinone was then added to IVT nicardipine and IV milrinone. The combination of IVT nicardipine, IV milrinone, and rescue therapy with IVT milrinone was continued for a total of 7 days. TCD mean velocities decreased into the mild to moderate range within 2 days of the patient receiving this combined regimen and remained globally low thereafter. CONCLUSION: This case illustrates the potential benefit of using dual IVT vasodilators to improve outcomes for pediatric patients with refractory cerebral vasospasm.
RESUMEN
There are several methods to achieve the therapeutic sacrifice of the vessel, coiling brings the most commonly used. Penumbra occlusion device (POD) system is a newer modality for therapeutic large vessel occlusion, and it is the Food and Drug Administration approved only for peripheral vessels. We report a case where therapeutic vertebral artery (VA) occlusion was achieved with the POD system and Ruby coils for the first time. A patient was diagnosed with a new malignant-appearing tumor of the cervical spine. A conventional angiogram showed multiple tiny arterial feeders from the VA beyond scope of coil/onyx embolization, so we performed a balloon occlusion test followed by therapeutic sacrifice of the VA. A successful VA occlusion was achieved with significant reduction in the tumor blush, followed by open resection of the tumor. The patient had favorable postoperative course and without any neurological symptoms attributed to the VA occlusion.
RESUMEN
Solitaire FR device is a Food and Drug Administration-approved device for mechanical thrombectomy. It has been tested in various clinical trials for its safety and efficacy. We report a case of inadvertent detachment of the Solitaire FR device at stent-stent wire interface while performing mechanical thrombectomy. We review a rare phenomenon of retained Solitaire FR stent retriever in situ and discuss technique of avoidance and its management.
