Cerebral amyloid angiopathy (CAA) is a degenerative neurovascular disease in which the protein amyloid-beta accumulates in the vessel wall of cortical and leptomeningeal arteries. This may lead to acute lobar cerebral haemorrhage, which in case of CAA is fatal in 10-30% of cases. CAA may also present with transient focal neurological episodes (TFNE), the symptoms of which may mimic a transient ischaemic attack (TIA). Read More

Embryonic vascular development is achieved through the complex arrays of differentiation, proliferation, migration and mutual interaction of different cell types, and visualization as well as purification of unique cell populations are fundamental in studying its detailed mechanisms using in vivo experimental models. We previously demonstrated that Tmem100 was a novel endothelial gene encoding a small transmembrane protein, and that Tmem100 null mice showed embryonic lethality due to severe impairment of vascular formation. In the present study, we generated an EGFP reporter mouse line using a 216 kb genomic region containing mouse Tmem100 gene. Read More

Objective: The aim of this study was to evaluate the maternal-fetal Doppler patterns in pregnant women recovered from COVID-19.

Methods: This prospective case-control study was conducted in Ankara City Hospital between July 1, 2020 and August 30, 2020. Thirty pregnant women who were diagnosed with COVID-19 and completed the quarantine process were compared with 40 healthy pregnant women in terms of the fetal Doppler parameters. Read More

Microvascular anastomosis is a critical procedure in cerebral bypass surgeries. In some rare cases, the extraluminal interrupted technique is not optimal because the vessels are immobile and cannot be rotated, and anastomosis can be performed effectively through the intraluminal continuous suturing technique. The authors reported the application of the intraluminal continuous suturing technique in microanastomosis training with silicone tube, rat's common iliac arteries and abdominal aorta. Read More

Background: Dural arteriovenous fistulas (DAVFs) are pathologic vascular connections that shunt dural arterial flow directly to dural venous drainage. Only a few isolated case reports describe syncope on presentation. We report the first case of DAVF causing recurrent, progressive syncope in an otherwise asymptomatic patient. Read More
