Background: A case of high-flow cervical vertebro-vertebral arteriovenous fistula (VVAVF), which was occluded with detachable coils by the transarterial/transvenous double-catheter technique and balloon anchoring technique, is reported.
Case Description: A 32-year-old male who had a history of dilated cardiomyopathy, heart failure, and arrhythmia under anticoagulation presented with a neck bruit after a right internal jugular vein puncture. A high-flow VVAVF between the right vertebral artery (VA) and vertebral vein (VV) was revealed by ultrasonography and angiography. To extirpate the shunt while preserving the right VA without using a stent to avoid antiplatelet therapy, the double-catheter technique was used to occlude the vein and shunt tightly, 1 catheter from the venous side and the other from the VA to the VV through the shunt. Finally, stabilization of the coil cage in the dilating VV was secured by placing a balloon distally as an anchor and successfully occluding the shunt with small amounts of coils only on the venous side. The shunt and cervical bruit disappeared immediately after the treatment, and no recurrence was observed.
Conclusions: The double-catheter technique and balloon anchoring technique used in this case seem effective for transvenous embolization of VVAVF when preservation of the VA is desired.

Transcatheter aortic valve replacement for aortic regurgitation following valve sparing root replacement: a case series.

Background: Valve sparing aortic root replacement (VSARR) is a treatment for aortic root dilatation and aortic regurgitation (AR), which preserves the aortic valve. However, AR may recur, and redo surgery often carries high risk. Transcatheter aortic valve replacement (TAVR) can be performed but there is a paucity of literature to guide procedural planning.

Purpose: The double-flap technique (DFT) is an anti-reflux reconstruction procedure performed after proximal gastrectomy (PG), but its complexity and high incidence of anastomotic stenosis are problematic. We conducted this study to demonstrate the efficacy of robot-assisted DFT, with refinements, to address these issues.
Methods: Surgical outcomes were compared between the following procedures modified over time at our institution: conventional open DFT (group O, n = 16); early robotic DFT (group RE, n = 19), which follows the conventional open PG approach; and late robotic DFT (group RL, n = 21), which incorporates refinements to the early robotic DFT technique by exploiting more of the robotic capabilities available.

Article Synopsis
- - Colorectal cancer is highly prevalent, accounting for nearly 10% of cancers and 9.2% of annual deaths, making improved detection methods critical.
- - Robotic "front-wheel" navigating colonoscopes provide a less painful alternative to traditional methods by reducing discomfort during examinations through enhanced anchoring technologies.
- - The study introduces a dumbbell-shaped balloon anchoring actuator (DBAA) that improves anchoring force while minimizing trauma to the colonic wall, with experimental results supporting its effectiveness compared to traditional techniques.
Safety and Efficacy of Pivot-Balloon for Severe Tricuspid Regurgitation: The First-in-Man Experiences.

Background And Objectives: Among various emerging catheter-based treatments for severe tricuspid regurgitation (TR), the spacer device can reduce the regurgitation orifice without manipulating the valve leaflet. However, its clinical application has been hampered by traumatic anchoring to the myocardium and the coaxial alignment of the balloon resulting in insufficient TR reduction. This study aimed to evaluate the early-stage safety, technical feasibility, and preliminary efficacy of the novel atraumatic vertical spacer in patients with isolated severe TR.

Article Synopsis
- - Hemorrhage is the main cause of preventable death in trauma situations, leading to military and civilian advancements in medical practices, particularly through the use of tourniquets to manage extremity bleeding and save lives.
- - While tourniquets have significantly decreased deaths from bleeding in military settings, noncompressible hemorrhage still poses a major risk, especially before patients receive definitive medical care.
- - The study explores using a small, disposable pressure monitor during resuscitative endovascular balloon occlusion of the aorta (REBOA) to enhance blood pressure monitoring, facilitate better resuscitation practices, and reduce the need for blood products in extreme environments.
