Successful Mechanical Thrombectomy for Bilateral Anterior Cerebral Artery Occlusions in a Rare Anatomical Variant: A Case Report.
Int Med Case Rep J
January 2025
Department of Cardiology, Rugao Affiliated Hospital of Nantong University, Rugao People's Hospital, Nantong, Jiangsu, People's Republic of China.
Background: Acute ischemic stroke (AIS) is usually caused by acute occlusion of the cerebral artery. Bilateral anterior cerebral arteries (ACAs) originating from the anterior communicating branch of the same internal carotid artery are a rare anatomical variation in clinical practice. Mechanical thrombectomy (MT) of simultaneous acute occlusion of the bilateral ACAs with this variation has rarely been reported.

Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is an unwarranted complication associated with high mortality. The current TAVI practices recommend a multidetector computed tomography (MDCT) evaluation of the aortic valve, the left ventricular outflow tract, and the aortic root to determine the conventional risk factors for coronary obstruction like low-lying coronary ostia and narrow sinuses of Valsalva, mandating prophylactic coronary protection or native valve leaflet modification in high-risk patients. Despite optimal anatomy, acute coronary occlusion can still occur due to multiple mechanisms, one of which is coronary embolism due to thrombus, calcium, or native aortic valve fragments.

To access its online representations, visual working memory (VWM) relies on a pointer-system that creates correspondence between objects in the environment with their memory representations. This pointer-system allows VWM to modify its representations using a process called updating. When the pointer is invalidated, however, VWM triggers a process called resetting in which the no longer relevant representation and pointer are replaced.

A 45-year-old female with poorly controlled HTN presented with sudden, painless bilateral vision loss over 12 hours. On examination, she had only light perception in both eyes, with normal fundoscopy and no focal neurological deficits. Laboratory tests revealed mildly elevated creatinine and proteinuria.

J Med Case Rep
January 2025
Faculty of Medicine, Nangarhar University, Nangarhar, Afghanistan.
Background: Central retinal vein occlusion and cilioretinal artery occlusion are rare but serious ocular conditions that can lead to significant visual impairment. While few cases of central retinal vein occlusion and cilioretinal artery occlusion have been individually reported, concurrent occlusion of both vessels is extremely rare, particularly in younger patients without traditional vascular risk factors. We present the first reported case of simultaneous central retinal vein occlusion and cilioretinal artery occlusion in a young female patient associated with short-term use of progestin-only oral contraceptives (OCPs).
