Parieto-occipital scalp arteriovenous malformation with drainage into the posterior superior sagittal sinus: A case report.
SAGE Open Med Case Rep
March 2024
Al Ahli Hospital, Hebron, Palestine.
This case report presents the unique clinical presentation of an 18-year-old female patient with an 8-year history of a progressively enlarging pulsatile mass in the left parieto-occipital region of her scalp. Remarkably, there was no history of trauma, headache, or other associated neurological deficits. Advanced imaging techniques, including computed tomography angiography and magnetic resonance imaging, revealed a vascular lesion consistent with an arteriovenous malformation beneath the scalp.

Venous malformation (VM) of bladder is uncommon. We report the case of a VM involving bladder that was initially misdiagnosed as endometriosis based on symptomatology, histology and imaging. After failure of hormonal agent and increasing symptoms, a laparoscopic partial cystectomy was performed with a rapid improvement.

Large head and neck arteriovenous malformations are notoriously difficult to manage given their location and propensity for extreme hemorrhage. We propose a unique approach utilizing a Hyperform balloon and percutaneous Surgiflo sclerotherapy to provide intraoperative hemostatic stability during the excision of a left-sided scalp arteriovenous malformation. In a hybrid operating room a microcatheter balloon was fed into the left external carotid artery for occlusion of the malformation's main blood supply, and subsequently followed with digital subtraction angiography guided sclerotherapy of selective vessels.

Department of Radiology, Obafemi Awolowo University Teaching Hospitals Complex, Ife, Nigeria.
Aim: To determine the Doppler indices of the umbilical arteries in normal singleton pregnancy with a view to generating local reference ranges.
Methods: In this prospective, cross-sectional study, 400 pregnant women at 15-39 weeks' gestational age, with estimated fetal weight within the 10th and 90th percentile, no fetal malformation(s), and without any history of maternal medical disease, were recruited. Umbilical arteries were assessed on ultrasound, with the subjects in the supine position.
Endovascular treatment of arteriovenous malformations.
Handb Clin Neurol

Department of Neurosurgery, Methodist Hospital, Houston, TX, USA.
Cerebral arteriovenous malformations (AVM) are tangles of blood vessels that permit shunting of blood from the arterial to venous phase without intervening capillaries. The malformation's arterialization of a low-pressure system creates a risk of rupture that is substantially higher when associated with an aneurysm. The annual hemorrhage rate is 2.
