Intentional staged embolization via the "highway bypass" using a radial artery graft for a large posterior circulation aneurysm: illustrative case.
J Neurosurg Case Lessons
January 2025
Department of Neurosurgery, Kanto Rosai Hospital, Kanagawa, Japan.
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.
First-trimester Doppler Ultrasound for Predicting Successful Management of Pregnancy with Recurrent Pregnancy Losses Due to Antiphospholipid Syndrome and Thrombophilia: A Cohort Study.
J Hum Reprod Sci
December 2024
Department of Obstetrics and Gynecology, Faculty of Medicine Airlangga University, Airlangga University Hospital, Surabaya, Indonesia.
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.

Cardiovasc Diabetol
January 2025
Department of Radiology, West China Hospital, Sichuan University, 37# Guo Xue Xiang, Chengdu, 610041, Sichuan, China.
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.

Transplant Proc
January 2025
Departamento de Imágenes Diagnósticas, Fundación Valle del Lili, Cali, Colombia.
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.

January 2025
Department of Anatomy, Ankara University School of Medicine, Ankara, Turkey. Electronic address:
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.
