Endovascular access to the meningohypophyseal trunk.

چکیده
SUMMARY We describe a novel technique to selectively catheterize the meningohypophyseal trunk (MHT) and its branches. We emphasize the difficulty in accessing the MHT via an ipsilateral approach because of the geometric orientation of this vessel to the parent internal carotid artery.

The artery of Bernasconi and Cassinari: a morphometric study for superselective catheterization.
BACKGROUND AND PURPOSE The artery of Bernasconi and Cassinari is an important infraclinoid branch of the internal cerebral artery. It is of neuroendovascular relevance in view of its supply to complex lesions such as meningiomas and arteriovenous malformations in the tentorial and falcotentorial regions. The present microanatomic study attempts a morphometric elucidation of this slender but imp...

Pseudoaneurysms (PsA) and arteriovenous fistulae (AVF) of the thyrocervical trunk and its branches are rare complications of traumatic or iatrogenic arterial injuries. Most such injuries are iatrogenic and are associated with central venous catheterization. Historically, thyrocervical trunk PsA and AVF have been managed with open surgical repair; however, multiple treatment modalities are now a...
