Abstract
The detachable balloon catheter (DBC) was a revolutionary technique for the treatment of cerebrovascular pathologies. 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. This technique was a monumental stride in the history of neurointervention and helped propel the specialty to the current era of patient-specific interventions.
