Due to technical limitations, small, distal, and tortuous intracranial pathology is sometimes out of reach of the current armamentarium of microcatheters designed for intracranial coil embolization. The Marathon microcatheter (Medtronic, Minneapolis, Minnesota, USA), designed specifically for the delivery of Onyx, is longer and more flexible than most coil delivery catheters. We report on nine patients (three with arteriovenous fistula, three with arteriovenous malformation, two with intracranial aneurysm, and one with tumor) where Marathon was used to deliver commercially available platinum coils. We also conducted laboratory compatibility testing and conclude that the Marathon can be used as a coil delivery catheter for Barricade coils (Blockade Medical, Irvine, California, USA) with diameter less than 0.012 in.

The anatomical characteristics of middle cerebral artery aneurysms make endovascular treatment difficult. This study evaluated the efficacy and safety of endovascular treatment of unruptured middle cerebral artery aneurysm in preventing rupture. A retrospective review of patients who underwent coil embolization for unruptured middle cerebral artery aneurysm between 2006 and 2022 at Nagoya University Hospital with at least 12 months followed up was conducted.

Selecting an appropriate microcatheter tip shape for paraclinoid aneurysms is difficult. Therefore, we devised an original simple and uniform three-dimensional (3D) spiral-shaping method of microcatheter and validated the characteristics and usefulness of this method for coil embolization of paraclinoid aneurysms using patient-specific silicone models. These silicone models were produced based on clinical data from four patients with four paraclinoid aneurysms that underwent endovascular treatment using the 3D spiral-shaping method.

Background: This study evaluates the safety and effectiveness of coil embolization of the superior rectal artery for both emergency and elective treatment of rectal bleeding caused by Goligher grade 4 hemorrhoids, where surgery is contraindicated.
Methods: Between 2019 and 2024, 18 patients (11 males, 7 females) with a mean age of 65±10.3 years were included in the study.
Transapical coil embolization for subannular aortic pseudoaneurysm.
Multimed Man Cardiothorac Surg
January 2025
Aortic pseudoaneurysm is a rare but life-threatening complication following aortic surgery. Although surgical repair remains the gold standard for treatment, alternative approaches such as transcatheter strategies are increasingly considered viable options, particularly in patients with high surgical risk due to comorbidities, anatomical challenges or technical constraints. We present the case of a 72-year-old male patient who developed a subaortic pseudoaneurysm during radiological follow-up after a previous Bentall operation.
