Preparedness of neurosurgery graduates for neuroendovascular fellowship: a national survey of fellowship programs.

OBJECT: Endovascular interventions have become an essential part of a neurosurgeon's practice. Whether endovascular procedures have been effectively integrated into residency curricula, however, remains uncertain. The purpose of this study was to assess the preparedness of US neurosurgery graduate trainees for neuroendovascular fellowship. METHODS: A multidomain, global assessment survey was sent to all directors/faculty of neuroendovascular fellowship programs involved in training of US neurosurgery graduates. Surveyees were asked to assess trainees as they entered fellowship. RESULTS: The response rate was 78% (25/32). Of respondent program directors, 38% reported that new fellows did not know the history and imaging of the patient and 50% were unable to formulate an appropriate treatment plan. As many as 79% of fellows were unfamiliar with endovascular devices and 75% were unfamiliar with angiographic equipment. Furthermore, 58% of fellows were unable to perform femoral access, 54% were unable to perform femoral closure, 79% were unable to catheterize a major vessel, 86% were unable to perform a 4-vessel angiogram, and 100% were unable to catheterize an aneurysm. Additionally, program directors reported that over 50% of fellows could not recognize neurovascular anatomy and 54% could not recognize/classify vascular abnormalities. There was an overall agreement that fellows demonstrated professionalism and interest in research and had good communication/clinical skills. CONCLUSIONS: The results of this study suggest potential gaps in the training of neurosurgery residents with regard to endovascular neurosurgery. In an era of minimally invasive therapies, changes in residency curricula may be needed to keep pace with the ever-changing field of neurosurgery.

Endovascular stroke intervention in the very young.

OBJECT: This study aims to evaluate the use of endovascular therapy to treat very young (≤ 35 years) patients with acute ischemic stroke from large vessel occlusion. METHODS: We identified from a prospectively maintained database young patients (≤ 35 years) undergoing endovascular intervention for AIS at two cerebrovascular referral centers. The study only included patients with a confirmed large vessel occlusion. Modified Rankin scale (mRS) scores were determined at 90 days during a follow-up visit. RESULTS: A total of 15 patients met the inclusion criteria. Mean age was 27.93 years ± 6.75 years (range: 9-35 years). On admission, the mean NIHSS score was 14.07 ± 9.16. Mechanical thrombectomy was performed using the Solitaire FR device in 4 of 15 (26.67%) patients and the Merci/Penumbra systems in 11 (73.33%) patients. Successful recanalization (TICI 2-3) was achieved in all but one patient (14/15; 93.33%). Only one patient (6.67%) had a hemorrhagic conversion following intervention; he later expired. The rate of 90-day favorable outcome (mRS 0-2) was 86.67% (13/15). CONCLUSION: Endovascular treatment in the very young population may be carried out with limited complications and attain remarkably high rate of recanalization and favorable outcome. This study supports the role of aggressive management strategies for very young patients with large vessel occlusion.

Update on intra-arterial chemotherapy for retinoblastoma.

The tools for managing retinoblastoma have been increasing in the past decade. While globe-salvage still relies heavily on intravenous chemotherapy, tumors in advanced stage that failed chemotherapy are now referred for intra-arterial chemotherapy (IAC) to avoid enucleation. However, IAC still has many obstacles to overcome. We present an update on the indications, complications, limitations, success, and technical aspects of IAC. Given its safety and high efficacy, it is expected that IAC will replace conventional strategies and will become a first-line option even for tumors that are amenable for other strategies.
