Cavernous malformations (CMs) have long been recognized as one of the major clinicopathologic categories of vascular malformations of the nervous system. CMs have been included in the descriptions of cryptic or occult vascular malformations , a term that has been…
Dural arteriovenous fistulas (DAVFs) are abnormal arteriovenous shunts within the dural leaflets. DAVFs have similar hemodynamics to brain arteriovenous malformations (AVMs), with low resistance, high-flow arteriovenous shunting, and a higher annual rupture risk than AVMs. They are usually located within…
Acknowledgments The authors thank the staff of Neuroscience Publications at Barrow Neurological Institute for their assistance with the preparation of this manuscript. Background Aneurysms of the midbasilar and lower basilar artery (BA) are located below the level of the superior…
The anterior communicating artery (ACoA) aneurysm is the most common aneurysm encountered in neurosurgical practice, accounting for one-quarter to one-third of all microsurgically treated aneurysms in published experiences and 18.4% of the senior author’s experience with 4545 aneurysms. This aneurysm…
Clinical Pearls Superior cerebellar artery aneurysms are often favorable for clipping because they tend to project laterally off of the midline, which places them directly in the well-visualized carotid-oculomotor triangle. They are associated with less morbidity than basilar apex aneurysms…
Acknowledgments We thank the staff of Neuroscience Publications at Barrow Neurological Institute for assistance with manuscript preparation. Pearls The dynamic nature of iAVMs is ascribed to complex molecular and physiologic processes that contribute to their growth, regression, remodeling, and de…
Acknowledgment We thank the staff of Neuroscience Publications at Barrow Neurological Institute for assistance with manuscript preparation. Pearls Intraoperative bleeding from an iAVM is best categorized as arterial, venous, or nidal. Arterial bleeding is best managed with bipolar cautery directly…
