Flow- and caliber-matched dual bypass for fusiform MCA bifurcation aneurysm.
Complex fusiform aneurysms of the middle cerebral artery (MCA) bifurcation remain challenging when the diseased segment incorporates both M2 trunks, precluding reconstructive clipping or endovascular options. We present a video article demo…

Contemporary adverse event profile of microsurgery for intracranial unruptured aneurysms in high-volume microsurgical centers: the international PRAEMIUM study.
[OBJECTIVE] Objective values on procedural risk are essential to facilitate informed consent and optimize clinical decision-making in patients with unruptured intracranial aneurysms (UIAs). While robust heuristics, such as the PHASES (popul…

Risk Models for Adverse Events in Microsurgery for Intracranial Unruptured Aneurysms.
[BACKGROUND AND OBJECTIVES] Preventive treatment of unruptured intracranial aneurysms (UIAs) requires assessment of treatment risks vs expected benefit. Although established scores exist to estimate rupture and growth risk, currently, no ex…

The role of surgical disconnection for posterior fossa pial arteriovenous fistulas and dural fistulas with pial supply: an illustrative case series.
[BACKGROUND] Pial arteriovenous fistulas (pAVFs) are rare vascular malformations characterized by high-flow arteriovenous shunting involving a cortical arterial supply directly connecting to venous drainage without an intermediate nidus. Du…

Microsurgical Obliteration of Craniocervical Junction Dural Arteriovenous Fistulas: Multicenter Experience.
[BACKGROUND] Dural arteriovenous fistulas (dAVFs) located at craniocervical junction are extremely rare (1%-2% of intracranial/spinal dAVFs). Their angio-architectural complexity renders endovascular embolization to be challenging given mul…

Adjuvant stereotactic radiosurgery with or without postoperative fractionated radiation therapy in adults with skull base chordomas: a systematic review.
[OBJECTIVE] The objective of this retrospective study was to compare the survival of patients with biopsy-proven skull base chordoma who had undergone stereotactic radiosurgery (SRS) with versus without prior fractionated radiation therapy …

Combined Internal Maxillary Artery to Middle Cerebral Artery and In Situ Middle Cerebral to Middle Cerebral Artery Bypass for Complex Middle Cerebral Artery Aneurysm: 3-Dimensional Operative Video.
Flow-replacement revascularization and/or flow augmentation surgery may be necessary for safe deconstruction of complex middle cerebral artery (MCA) aneurysms. Roughly 1% to 2% of all MCA aneurysms have angiographic features prohibiting sta…
