SummaryEthmoidal dural arteriovenous fistulas (DAVFs) are rare lesions, accounting for approximately 10% of intracranial DAVFs.1 2 As ethmoidal DAVFs commonly demonstrate cortical venous drainage, treatment is always warranted.2-6 Endovascular transvenous embolization has been increasingly reported as an effective and safe treatment for ethmoidal DAVFs, and since occlusion of the central retinal artery and resulting blindness are not a concern, it has an advantage over transarterial embolization.3-6 To ensure curative embolization, we adopted the transvenous retrograde pressure cooker technique (RPCT), creating a plug with n-butyl cyanoacrylate (NBCA) in the draining vein to allow a more comprehensive and efficient injection of Onyx (Medtronic, MN) while avoiding excessive reflux.7 8 In this technical video (video 1), we report the first case using the transvenous RPCT for successful Onyx embolization of an ethmoidal DAVF, with emphasis on the technical nuances of the RPCT and important tips to avoid periprocedural complications. neurintsurg;16/7/742/V1F1V1Video 1 Video demonstrating Onyx embolization of an ethmoidal dural arteriovenous fistula using the transvenous retrograde pressure cooker technique.

This is a novel case of idiopathic chylopericardium and chylothorax in a young male who had no significant medical history. He first presented with dyspnea due to idiopathic chylopericardium, which was refractory to medical and surgical treatments, including a medium-chain triglyceride diet, octreotide, and video-assisted pericardial window. The chylopericardium persisted and progressed to concomitant left-sided chylothorax.

Purpose: To assess the treatment outcomes of vascular plug-assisted retrograde transvenous obliteration (PARTO) for gastric varices based on hemodynamic changes observed in pre- and post-procedural CT scans.
Methods: This single-center study included 43 patients with gastric varices who underwent PARTO between June 2017 and December 2023. Peri-procedural CT and endoscopic findings were retrospectively reviewed to analyze the afferent and draining veins of gastric varices, identify any residual varices or afferent veins after treatment, assess the technical and clinical successes, and determine statistically significant variables associated with clinical success.

Ectopic Variceal Bleeding is a rare complication of portal hypertension, often difficult to manage and potentially life-threatening. However, established guidelines directing treatment are lacking. This report presents a 51-year-old female with hepatitis B-related cirrhosis, who experienced rare small intestinal bleeding due to varicose veins in the superior mesenteric vein and left ovarian vein.

Article Synopsis
- A 52-year-old woman with a history of liver surgery developed gastric varices, which posed a risk of rupture.
- A specialized procedure called balloon-occluded retrograde transvenous obliteration (BRTO) was attempted using a double-balloon catheter, but initial venography did not visualize the varices.
- Ultimately, the treatment was successful by injecting a sclerosing agent through the catheter system, effectively embolizing the varices and highlighting the method's effectiveness for complex vascular cases.
