RESUMEN
Spinal dural arteriovenous fistulae (SDAVF) are rare diseases that exhibit abnormal connections between arteries and veins. They are even rarer in the pediatric population and pose diagnostic and treatment challenges for physicians. Its presentation varies depending on the site and size of the SDAVF. Multiple management options are available, which are usually tailored depending on the patient's condition. Here, we present a rare case of SDAF in a four-year-old girl who initially presented with bilateral lower limb weakness. The patient was then treated successfully using primary major fistula point stenting and intra-stent coiling, with complete closure achieved. Full recovery was achieved over the course of follow-ups. The deep analysis of SDAVF, its classification, and the utilization of the best available endovascular tools by a dedicated neurovascular team offer the best outcome in dealing with complex spinal neurovascular pathologies.
RESUMEN
OBJECTIVE: Endovascular treatment of cerebrovascular diseases is often challenging due to small caliber, tortuous distal vessels. Several devices and techniques have evolved to overcome these challenges. Recently, a low profile dual lumen microballoon catheter, specifically designed for distal navigation is employed for neurovascular procedures. Due to its recent advent, scarce data is available on clinical utility and safety of Scepter Mini. The aim of this case series is to report our initial experience with Scepter Mini in the management of various cerebrovascular diseases. METHODS: All interventional neurovascular cases performed using Scepter Mini between January 2020 till April 2021 were included. Data regarding patient demographics, procedural details and complications was retrospectively collected from patient's electronic medical record and procedure reports. RESULTS: Total twelve embolization procedures were performed in eleven patients, including six brain arteriovenous malformation, two dural arteriovenous fistula, one vein of Galen malformation and three hyper-vascular glomus tumor embolizations. All procedures were successfully performed with adequate penetration of the embolic agent. Complete embolization was performed in six procedures, while intended partial embolization was performed in the rest of procedures. Scepter Mini was solely used in ten procedures, however in the other two embolization procedures it was used as an additional conjunct tool to complete the intended embolization. No balloon related complication was observed in any procedure. CONCLUSIONS: Scepter Mini dual lumen microballoon catheter is safe and feasible for delivery of liquid embolic agents for cerebrovascular embolization procedures.
RESUMEN
BACKGROUND: Recently there is a trend for radial first which advocates radial artery access as the first choice to perform diagnostic and interventional neurovascular procedures. Although safer than the conventional common femoral artery access, it is associated with a high rate of radial artery occlusion. Distal radial artery access is recently proposed to avoid this complication. This study aims to assess the feasibility and safety of distal radial artery access across a wide range of interventional neurovascular procedures. MATERIALS AND METHODS: All Interventional neurovascular cases attempted via distal radial artery access from September 2019 till March 2021 were included in the study. Data regarding patient demographics, distal radial artery diameter, access site cannulation, size of the sheath, procedural details including success rate and complications were collected. RESULTS: During the study period, 102 patients underwent 114 procedures via the distal radial artery approach. The mean age of patients was 41.9 ± 15.2 years. Overall procedure success rate via DRA was 94.7% (108/114). 72 diagnostic cerebral angiograms and 36 interventional procedures were successfully completed while six procedures required switching to alternate access. CONCLUSION: Distal radial artery access is a safe and feasible option for diagnostic cerebral angiography and a wide range of neurovascular procedures.
