Bridging the gap between neuroimaging and neurosurgery: a case of epidural arteriovenous fistula with an intradural presentation. Illustrative case.
J Neurosurg Case Lessons

Department of Neurosurgery, Miller School of Medicine, University of Miami, Miami, Florida.
Article Synopsis
- Epidural arteriovenous fistulas (eAVFs) are rare vascular issues often confused with intradural ones, impacting treatment and outcomes.
- A case of a 68-year-old man initially diagnosed with a likely intradural fistula was actually found to have an epidural lesion during surgery, leading to significant improvement after treatment.
- The findings emphasize the need for better imaging techniques and a collaborative medical approach to accurately identify and treat spinal vascular malformations.

Article Synopsis
- Hemorrhagic brain micro-AVMs are common in pediatric cases but usually have low bleeding rates, even in conditions like hereditary hemorrhagic telangiectasia that involve multiple malformations.
- A 10-year-old girl with multiple hemorrhagic micro-AVMs required emergency surgery due to hematoma; intraoperative findings revealed complex vascular structures and atypical bleeding sources.
- Superselective angiography proved essential for identifying micro-AVMs and informing treatment, while also highlighting the need for caution due to the potential impacts of invasive procedures on vascular sensitivity and visibility.
Comparison of Superselective Renal Artery Embolization versus Retroperitoneal Laparoscopic Partial Nephrectomy in Ruptured Hemorrhagic Renal Angiomyolipoma: A Single-Center Study.

Department of Vascular Surgery, The Second Hospital of Tianjin Medical University, Tianjin 300211, China.
Article Synopsis
- The study aimed to evaluate the effectiveness of two treatment methods—superselective arterial embolization (SAE) and retroperitoneal laparoscopic partial nephrectomy (RLPN)—for ruptured hemorrhagic renal angiomyolipoma, providing guidance for treatment choices.
- A total of 24 patients from the Second Hospital of Tianjin Medical University were analyzed, with 10 receiving SAE and 14 undergoing RLPN, comparing various clinical outcomes like operation time, blood loss, and recovery metrics.
- Results showed no major differences in recovery time or costs, but notable distinctions in surgical duration and intraoperative blood loss, with SAE resulting in less blood loss and shorter surgery time while both methods effectively reduced tumor size over a
Transarterial Embolization With N-Butyl-2-Cyanoacrylate for Rapidly Enlarging Distal Anterior Choroidal Artery Aneurysm Associated With Moyamoya Disease: A Case Report.

Peripheral aneurysms associated with moyamoya disease, particularly those originating from the anterior choroidal artery, often have a poor prognosis and are typically managed with endovascular treatments. Comprehensive imaging diagnostics and anatomical expertise are critical in minimizing ischemic complications during treatment. We present a case of a 55-year-old woman with a rapidly enlarging distal anterior choroidal artery aneurysm identified during an intracerebral hemorrhage associated with moyamoya disease.

Anastomotic leaks and stenoses remain critical complications in esophagectomy and are related to conduit perfusion. Surgical gastric preconditioning has been described but requires additional surgery and creates scar tissue, potentially hindering future operation. We sought to evaluate the feasibility and safety of percutaneous gastric preconditioning by angioembolization to improve perfusion of gastric conduits before esophagectomy in a high-risk patient cohort.
