Recanalizing acute ischemic stroke with carotid tandem occlusion (CTO) is technically challenging because distal embolic migration during revascularization can significantly influence outcomes. In this study, we aimed to introduce our coaxial balloon technique using a balloon-guiding catheter (BCG), angioplasty catheter, and aspiration catheter sequentially to prevent thrombus migration to a new vascular territory. We used this technique for six patients with CTO. Technical success with good revascularization of the CTO was achieved in all six patients (100%) without neurological complications, including one and five cases of modified Thrombolysis in Cerebral Infarction 2b and 3, respectively. The median duration of the procedure was 61 (interquartile range, 52-90) min. The mean National Institutes of Health Stroke Scale score at discharge was 3.5 (2-8), with favorable clinical outcomes at 90 days for three of six patients (50%). The coaxial balloon technique for CTO is safe and effective for revascularization in patients with acute ischemic stroke. Thrombectomy before proximal stenting was associated with shorter reperfusion times and better clinical outcomes. Therefore, this approach is recommended for tandem occlusions requiring stent angioplasty.

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.

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.

Coaxial trapping of guide extension catheters within a coronary artery allows for maximal support in delivering equipment; however, use of this technique within the left main coronary artery has been avoided due to concerns surrounding hemodynamic instability and vessel injury. We describe our initial experience with impromptu coaxial trapping of guide extension catheters within the left main coronary artery using the dual access rapid trap (DART) technique. Coaxial trapping of guide extension catheters within the left main coronary artery using DART enabled successful equipment delivery across balloon-uncrossable lesions.

Aerodynamic investigation of a bionic coaxial-rotors unmanned aerial vehicle (UAV) is performed. According to Chinese parasol seed features and flight requirements, the bionic conceptual design of a coaxial-rotors UAV is described. A solution procedure for the numerical simulation method, based on a multi-reference frame (MRF) model, is expressed, and a verification study is presented using the typical case.
