Efficacy of Pressure Cooker Technique in Redo Embolization for High-Flow Torcular Dural Sinus Malformation.
Neurointervention
February 2025
Department of Interventional Neuroradiology, Alfried Krupp Hospital Rüttenscheid, Essen, Germany.
Torcular dural sinus malformations (tDSMs) with high-flow fistulas pose complex management challenges due to their vascularity and the delicate neuroanatomy involved. This report presents the case of a child with tDSM and hydrocephalus, who underwent 3 staged embolization procedures but required a redo intervention due to residual malformation and venous hypertension. Utilizing the pressure cooker technique (PCT) in a redo setting allowed for high-pressure, targeted embolic delivery with minimized reflux, achieving near-complete occlusion and significant symptom relief.

Background: Previous studies have shown that when thrombectomy has failed, rescue intracranial stenting is associated with better clinical outcomes compared with failed reperfusion. However, comparative data regarding stent type are lacking.
Objective: To compare the procedural and clinical outcomes of balloon-mounted stents (BMS) with those of self-expandable stents (SES).
Subdermal contraceptive implant migration to pulmonary artery branch.
BMJ Case Rep

Radiology, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent, UK.
Subdermal contraceptive implants are now commonly used throughout the world. One of the rare complications of these implants is migration to the lungs due to misplacement of the implant during insertion, with only a limited number of cases documented. Here, we present a case where a subdermal contraceptive implant embolised in the subsegmental branch of the pulmonary artery within the anterobasal segment of the left lower lobe.

Neurological outcomes of patients with PA undergoing TAVI with modern valves require clarification as most trials examined balloon-expandable valves (BEV) and self-expandable valves in intermediate or high-risk patients, but not specifically in patients with PA. Our aim was to compare outcomes, including stroke and mortality, in well-matched patients with and without PA who received BEV during transfemoral TAVI procedures.

No Shinkei Geka
January 2025
Department of Neurosurgery, Japan Community Health Care Organization Tokyo Shinjuku Medical Center.
Middle meningeal artery embolization(MMAE) is an effective treatment for chronic subdural hematoma(CSDH). Retrospective analyses have indicated that MMAE for CSDH is not only minimally invasive but also highly safe, and is associated with a significantly lower recurrence rate than that of conventional treatments. However, there is no consensus regarding treatment strategies, including the patient-selection criteria, embolic materials, and procedural techniques.
