Background: No cerebral aneurysms on the feeder associated with hemangioblastomas that ruptured before resection have been reported. We report a patient with a ruptured flow-related aneurysm associated with cerebellar hemangioblastoma and a tumor feeder treated simultaneously by a single procedure of embolization using N-butyl cyanoacrylate before tumor removal.
Case Description: A 36-year-old female with a cerebellar tumor was admitted to our institute. Four days later, she suffered a massive subarachnoid hemorrhage mainly in the posterior fossa. Left vertebral angiograms showed an aneurysm on the feeding artery, posterior inferior cerebellar artery. Both the aneurysm and its main feeder were simultaneously treated by a single procedure of embolization using N-butyl cyanoacrylate. Their complete obliteration was confirmed angiographically. Four days after the procedure, we removed the tumor and the embolized aneurysm. The pathological diagnosis was hemangioblastoma and flow-related ruptured aneurysm.
Conclusion: Cerebral angiography should be performed to rule out vascular abnormalities such as cerebral aneurysms adjacent to the tumor in patients with hemangioblastoma who present with intracranial hemorrhage. We emphasize the usefulness of embolization with N-butyl cyanoacrylate for hemangioblastoma with ruptured feeder aneurysm, by which the aneurysm and the feeder could be simultaneously embolized.

Scalp arteriovenous fistula (AVF) is a rare vascular malformation that may present as a pulsatile scalp mass with complications like hemorrhage. We report a case of a large scalp AVF with recurrent bleeding, managed successfully with a multimodal approach. A 46-year-old man presented with a recurrently bleeding pulsatile scalp mass in the left temporal region, initially diagnosed as AVF following trauma.

Objective: A Leonis Mova (LM; SB Kawasumi, Kanagawa, Japan), one of the steerable microcatheters, has a remote-controlled flexible catheter tip manipulated with a dial in the hand grip, which enables operators to overcome complicated branching in endovascular surgeries. We report a case of a pituitary tumor in which the LM worked effectively as a distal access catheter (DAC) in tumor embolization.
Case Presentation: A female patient in her 70s complained of bitemporal hemianopsia, and an MRI revealed a pituitary tumor that appeared hypervascular.

This study aims to investigate the degree of penetration, permanence of occlusion, and vascular changes induced by a newly modified mixture of n-butyl cyanoacrylate (Glubran 2), ethanol, and Lipidol (GEL) in the endovascular treatment of experimental aneurysms induced in swine. Bilateral pouch aneurysms were created in the wall of the internal carotid artery in eighteen pigs. The sixteen aneurysms were treated with a new mixture of GEL with different component proportions.

This report details a 59-year-old female who underwent total gastrectomy with Roux-en-Y esophagojejunostomy for early gastric cancer, followed by percutaneous embolization for esophagojejunal (EJ) anastomotic leakage. Despite initial percutaneous drainage for fluid accumulation at the EJ site, subsequent CT revealed significant anastomotic dehiscence.

Article Synopsis
- The study focuses on evaluating the long-term outcomes and natural history of chronic subdural hematoma (cSDH) treatment using middle meningeal artery (MMA) embolization over a 12-month period.
- A retrospective analysis was conducted involving 49 patients who underwent MMA embolization, detailing patient demographics and various clinical outcomes, including symptom resolution and recurrence rates.
- Results indicated significant clinical improvement in patients within one month post-procedure, with many elderly patients (average age 73) experiencing previous trauma mainly due to falls.
