“Subclinoid” aneurysms grow superolaterally beneath the clinoid & can cause its erosion. Preoperative recognition can prevent intraoperative rupture during clinoidectomy. Read this old sobering classic paper by Roberto Heros.#MedEd #Neurosurgery #Medtwitter Eva Wu @thejns

There is no contralateral occlusion. “High bifurcation” is a relative concept, splitting the mandible is NEVER necessary. Mobilizing the posterior belly of digastric w/ fish hooks increases the upper limit of exposure &makes CEA doable. #Neurosurgery #MedEd #Medtwitter Eva Wu

How would you manage this 42F w/ intracranial recurrence of optic nerve sheath meningioma initially biopsied at OSH 5 yrs ago. R eye blind, L 20/20, EOMI. Observation? Radiation? If surgery, approach/extent of resection? #Neurosurgery #MedEd #MedTwitter Eva Wu  Journal of Neurosurgery WFNS

Launching the new #MorcosChallenge series of daily 8am EST educational tweets in #Neurosurgery #SkullBase #BrainTumor #Cerebrovascular. See attached explanation. Hope you will participate and share!

#MorcosChallenge: Given growth toward chiasm,modified cranioorbital w/anterior clinoidectomy &transection of R optic nerve used. Intracranial portion resected to prevent spread to left. Radiate orbit after. Complete resection avoided to prevent ophthalmoplegia, unless recurs.

#MorcosChallenge 22F w/sickle cell&bilat moyamoya now w/ transient LUE weakness. Neurointact. During STA-MCA bypass (1D2R), after sidetoside anastom to TM4&before endtoside to FM4 was done, there was intraop SAH&hyperemia. How do you handle this? #neurosurgery #MedEd Eva Wu

#MorcosChallenge: We did not do 2nd anastomosis to FM4&intentionally stenosed STA to decrease flow. Final bypass flow after clip-narrowing 40cc/mn. Ultrasound no hematoma. SSEP no change. Kept BP low-normal postop. No deficits. #neurosurgery Eva Wu CV Section Neurosurgical Atlas

#MorcosChallenge: 60M with horizontal diplopia with left gaze, hypacusis, gait instability. MRI included. How would you classify this lesion&what surgical approach if you operated? #neurosurgery #MedEd #MedTwitter Eva Wu @theJNS Neurosurgery Publications AANS Neurosurgical Atlas

Last week, we hosted a Surgical Techniques in Neurosurgery course at our facility in Salt Lake City. 25 residents got practical hands-on experience with Stryker's expansive cranial and spine portfolio. Special thanks to course directors: Dr. Morcos and Dr. Refai! #StrykerNS

#MorcosChallenge 26F w/HA, n/v, lesion in 4th ventricle&obstructive hydro. Underwent VP shunt&suboccip transtonsillar, tiny tumor carpet intentionally left on 4th ventricle floor. Path slides included. MRI 10mo postop w/recurrence throughout ventricular system. What is ddx?

An interesting exercise to understand pedicle anatomy. Screw trajectories are generally predictable and intra-op safety (in the absence of navigation) is aided by obtaining true AP fluoroscopy. Images taken from learnmuscles.com
