Dissecting aneurysm involving the posterior inferior cerebellar artery (PICA) are challenging because of its nature and anatomic relationship to medulla and lower cranial nerve. We introduce a case of ruptured dissecting aneurysm located at the proximal PICA treated with telescoping stents for flow diversion and dissection healing. A 49 years old female visited to the emergency room for ruptured dissecting aneurysm at right proximal PICA. Telescoping stent was deployed along the right vertebral artery to PICA covering the dissecting aneurysm bleb using two Low-profile Visualized Intraluminal Support Jr (LVIS Jr) stents. Three months follow up angiography revealed a disappearance of aneurysm bleb and healing of dissection by parent artery remodeling. Telescoping stent with LVIS Jr may be an effective treatment for dissecting aneurysm with small diameter (<2 mm) parent artery. Convenient navigation and targeted telescoping stent for minimizing metal coverage at perforating arteries are an advantage for this method.

According to the Japanese Association for Thoracic Surgery annual surgery survey, the number of aortic surgery has been increasing constantly in the last two decades, with the rates approximately doubling in each decade (5,167, 11,956, and 22,708 cases in 1999, 2009, and 2019, respectively). In 2019, aortic surgery was performed for 11,036 (49%) nondissecting unruptured aneurysm, 730 (3%) ruptured aneurysm, 6,351 (28%) acute type A aortic dissection, 1,412 (6%) chronic type A aortic dissection, 2,385 (11%) acute type B aortic dissection, and 703 (3%) chronic type B aortic dissection cases. The outcomes have been improving annually.

Objective: Evaluate sex differences in patients undergoing repair of acute type A aortic dissection (ATAAD).
Methods: Sex-stratified, single-center cohort study of patients undergoing ATAAD repair from 1997 to 2022. The primary outcome was aortic diameter at time of presentation with ATAAD.

Objective: To investigate the influence of cannabis consumption on the mid- and long-term surgical outcomes of patients with aortic aneurysms or dissections.
Methods: All individuals aged 18 years and older with more than 6 months of cannabis use at the time of surgical repair for cardiovascular disease (aortic aneurysms or aortic dissection) between 2007 and 2023 were eligible. Patients were stratified into 2 groups based on their preoperative history of cannabis use: cannabis users and noncannabis users.

Objective: A novel approach to 3-dimensional morphometry of the thoracic aorta was developed by applying centerline analysis based on least-squares plane fitting, and a preliminary study was conducted using computed tomography imaging data.
Methods: We retrospectively compared 3 groups of patients (16 controls without aortic disease, and 16 cases each with acute type B aortic dissection and congenital bicuspid aortic valve). In addition to the standard assessment indices for curvature κ and torsion τ, we conducted coordinate transformation based on the least-squares plane, divided the centerline into 3 representative features (transverse, anterior-posterior, and longitudinal displacements), and analyzed the overall and local displacement in each direction.
