High-resolution computed tomography (HRCT) and MRI allow the accurate detection of inner ear malformations
and are complementary to each other.
This volume contains 31 chapters that detail the management of intracranial arteriovenous malformations
and arteriovenous fistulas, focusing on surgical techniques, embolization, and radiosurgery, with emphasis on the risks and benefits of each therapeutic strategy, as well as the limitations of different treatments and situations favoring conservative management.
If lymphatic malformations
are dominant, soft-tissue swelling and enlargement will occur.
5%) system involved and total 41 types of individual malformations
were observed (Table 1).
Later, more congenital malformations
were linked to valproic acid, including oral cleft, cardiac and limb defects, developmental delays, lower IQ, and even autism.
MRI is the best imaging method for the diagnosis of VMs because it can distinguish low-flow VMs from high-flow arteriovenous malformations
and fistulas (3).
(ARM) are embryonic developmental disorders characterized by an absence of the anus or the rectum opening to an abnormal anatomical location.
Brain arteriovenous malformations
(AVMs) are abnormal, congenital connections between arteries and veins leading to arteriovenous shunting without intervening capillary network of vessels .
CHICAGO -- Thanks to convoluted terminology, not to mention confusion in the literature, physicians have been known to frequently misdiagnose vascular malformations
as hemangiomas, but an evolving understanding of their differences may lead to more precise diagnoses, according to a report at a symposium on vascular surgery sponsored by Northwestern University.
SUMMARY--Developmental venous anomalies are cerebral vascular malformations
that present normal venous drainage of cerebral tissue.
A hatch-year Swainson's hawk (Buteo swainsoni) recovered from Modoc County, California, USA, on August 12, 2012, had malformations
of the rear limbs consisting of bilateral polymelia and syndactyly.
are a heterogeneous group of congenital disorders that are defined by anatomic anomalies of the cerebellum, brainstem, and craniocervical junction, with downward displacement of the cerebellum, either alone or together with the lower medulla, into the spinal canal.
