Here, we present two patients with radial arteries less than 2 mm. One patient had a narrow neck intracranial aneurysm at the bifurcation of the left vertebral artery and posterior inferior cerebellar artery, which was embolized with the primary coiling technique. The other was a patient with a wide-necked extracranial aneurysm in the cavernous portion of the right internal carotid artery, which was embolized with the transcell technique with stent. We utilized a 3-Fr GS, distal access catheter, and a 0.0165-inch microcatheter for coil embolization. All aneurysms were completely occluded, without neurological or puncture site-related complications including subcutaneous hematoma, radial artery occlusion, and vasospasm. This report provides the first description of neurointervention using a 3-Fr GS.

Trends were evaluated using multivariable regression modeling, controlling for patient and hospital characteristics.ResultsA total of 8,935 patients underwent endovascular treatment for cerebral AVMs (6,500 unruptured and 2,435 ruptured). Endovascular treatment for unruptured AVMs declined significantly from 1195 cases in 2016 to 780 in 2022 (-34.7%, <i>p</i> = 0.020). Over the same period, the proportion of AVMs presenting ruptured increased from 15.7% to 25.7%, a 63.7% relative increase (<i>p</i> = 0.015). Multivariable analysis confirmed rising odds of rupture over time among endovascularly treated patients (OR = 1.12, 95% CI 1.00-1.25, <i>p</i> = 0.042).

The primary outcome was recurrence of cSDH requiring surgical rescue during follow up, and secondary outcomes were defined as >50% decrease in the maximum width of cSDHs on the longest follow-up computed tomography (CT) scan, complications following procedure, and improvement in modified Rankin scale (mRS) score.ResultsA total of 51 patients successfully underwent 72 MMA embolization procedures (96% of the total 75 cases in the cohort) combined with surgical evacuation. Seventy cases (93.3%) achieved at least 50% reduction in the size of the cSDHs on the last CT imaging. A surgical evacuation was required in five cases (6.7%) due to cSDH recurrence during the follow-up period. There were three complications (6.0%) related to embolization procedure.

It was used to treat carotid cavernous fistulas (CCFs), vertebro-jugular fistulas, arteriovenous malformations (AVMs), and aneurysms. The DBC became the foundation for neurointerventional techniques, leading to the development of coil embolization and bioactives. Our team selected relevant articles from PubMed published between 1974 and 2023. Articles were excluded if they did not discuss the use or development of the detachable balloon catheter or subsequent technologies. The DBC was used to occlude vessels, either temporarily or permanently. Dr Gerard Debrun implemented findings from Dr Fedor Serbinenko's research to develop an intravascular detachable balloon technique. He developed many variations using type I and type II balloon catheters that differed in size, length, and material, allowing for the personalization of treatment based on the lesion. This revolutionary thinking showed that every pathology has a different shape and anatomy that require a unique approach. The DBC would offer the first alternative to the conventional practice of carotid occlusion in CCF treatment at the time. The DBC would later be used in aneurysm occlusion and the embolization of AVMs, with additional benefit in traumatic vascular sacrifice. Although the DBC has largely been replaced, it is still useful in a small subset of patients, and has financial incentive as it is more affordable than coils.
