Microvascular transposition using Teflon sling technique

Mitchell W. Couldwell, Vance Mortimer, AS, and William T. Couldwell

Microvascular decompression is a well-established technique used to relieve abnormal vascular compression of cranial nerves and associated pain. Here the authors describe three cases in which a sling technique was used in the treatment of cranial nerve pain syndromes: trigeminal neuralgia with predominant V2 distribution, hemifacial spasm, and geniculate neuralgia and right-sided ear pain. In each case, the artery was mobilized from the nerve and tethered with a sling. All three patients had reduction of symptoms within 6 weeks.

Right frontotemporal craniotomy for ECA-to-MCA direct and indirect bypass and occipital artery indirect bypass to the posterior circulation: case report

Mitchell W. Couldwell, Samuel Cheshier, Philipp Taussky, Vance Mortimer, and William T. Couldwell

Moyamoya is an uncommon disease that presents with stenoocclusion of the major vasculature at the base of the brain and associated collateral vessel formation. Many pediatric patients with moyamoya present with transient ischemic attacks or complete occlusions. The authors report the case of a 9-year-old girl who presented with posterior fossa hemorrhage and was treated with an emergency suboccipital craniotomy for evacuation. After emergency surgery, an angiogram was performed, and the patient was diagnosed with moyamoya disease. Six months later, the patient was treated for moyamoya using direct and indirect revascularization; after surgery there was excellent vascularization in both regions of the bypass and no further progression of moyamoya changes. This case illustrates a rare example of intracerebral hemorrhage associated with moyamoya changes in the posterior vascularization in a pediatric patient and subsequent use of direct and indirect revascularization to reduce the risk of future hemorrhage and moyamoya progression.
