Objectives: Radial artery (RA) grafting has a clear survival advantage after coronary artery bypass grafting (CABG) in studies with predominantly male populations, but the impact on women's long-term survival is unclear. We sought to determine if the reported long-term survival benefit of RA versus saphenous vein (SV) grafting in the general CABG population is valid for women.
Methods: Between 1995 and 2010, 1339 female patients were alive 30 days after primary, isolated CABG with left internal thoracic artery (LITA) and additional RA or SV conduits as needed. Patients were evaluated based on RA use: 332 patients had RA and 1007 patients had SV. Of these, 283 RA patients were matched to SV counterparts using a nonparsimonious propensity model based on 45 patient variables.
Results: Kaplan-Meier estimated survivals for the matched RA women at 1, 5, 10, and 15 years were 99%, 93%, 80%, and 70% versus 97%, 87%, 72%, and 58% for the SV women (log rank, P = .018). For symptomatic patients, overall RA patency was 80%, which was not different from the LITA patency rate of 84% but was superior to the SV conduits patency rate of 56% (P < .001).
Conclusions: In women undergoing CABG with LITA grafting, use of an RA graft improves survival compared with use of an SV graft.

Background: The presence of significant tortuosity in access routes to aneurysms can interfere with catheter guidance and manipulation and significantly impact treatment strategies.
Observations: In this report, the authors combined intentional staged aneurysm embolization with the construction of a new direct access route, which they call a "highway bypass," for a symptomatic posterior circulation cerebral aneurysm that was difficult to access with a catheter. Notably, the highway bypass is used for catheter passage, and technical tips should be considered.

Background: Recurrent pregnancy loss (RPL) often stems from a hypercoagulable state that exacerbates conditions such as antiphospholipid syndrome (APS) and thrombophilia, leading to early placental issues. Although treatments such as low-molecular-weight heparin (LMWH) and low-dose aspirin (LDA) are used, outcomes vary. This study proposes using first-trimester Doppler ultrasound - specifically, uterine radial artery resistance index (URa-RI) at 8 weeks and uterine artery pulsatility index (Ut-PI) with pre-diastolic notching (Ut-notch) at 11-13 weeks - to better predict successful pregnancies and reduce risks of adverse outcomes.

Background: Ischemia with nonobstructive coronary arteries (INOCA) has high morbidity, mortality, and poor quality of life. Metabolic syndrome (MetS) is a complex of multiple cardiac metabolic risk factors, significantly increasing the risk of major adverse cardiovascular events in INOCA patients. The study aimed to investigate the aggravating effect of MetS on left ventricular (LV) deformation and function impairment in INOCA patients.

Background: Vascular thymus transplantation has been explored in animal models but remains untested in humans. Current approaches to congenital athymia involve avascular transplantation of allogeneic thymic tissue, which may delay immune recovery. Building on animal studies, we propose revascularization of thymic tissue in a human model.

Background: This study aims to demonstrate the 3-dimensional pattern of the nutrient vessels of the triquetrum using micro-computed tomography and determine the safe region for screw applications to the bone.
Methods: Seven fresh frozen cadavers' ulnar and radial arteries were injected with Microfil MV-117. Triquetral bones were dissected and examined using micro-computed tomography.
