Abstract:
Detachable tip microcatheters represent a novel advancement in neurovascular interventions, enhancing embolization procedures through improved precision, particularly in complex anatomical regions. These devices are especially advantageous for treating arteriovenous malformations (AVMs) and arteriovenous fistulas (AVFs), where traditional approaches are associated with risks such as catheter entrapment or vessel injury. In this study, the clinical application of second-generation detachable tip microcatheters was evaluated in three cases involving AVMs and AVFs. Microcatheters of varying lengths were employed for embolization, with pre-procedure assessments conducted using CT, MRI, and angiography. Procedural steps included access site preparation, guide catheter insertion, microcatheter navigation, embolic agent delivery, and controlled tip detachment. Post-procedure imaging and clinical evaluations were performed to assess outcomes. Successful embolization was achieved in all three cases, with significant lesion reduction, occlusion of feeding arteries, and resolution of fistulous components. Minimal complications were reported, and follow-up evaluations demonstrated symptom resolution, including reduced headaches and improved neurological function. The sleeve plays a crucial role in controlling the detachable tip of the microcatheter. During the pull-out procedure, the applied force causes the tip to detach precisely at the target location, ensuring accurate delivery of embolic agents or other therapeutic materials. In conclusion, detachable tip microcatheters were effective in achieving precise embolization with favorable outcomes. Further research is required to assess their long-term safety, efficacy, and cost-effectiveness and to facilitate their integration into standard neurovascular practices.
