Open surgical management of a ruptured intracranial aneurysm in Klippel-Trenaunay-Weber (KTW) syndrome.

A 24-year-old man with a history of Klippel-Trenaunay-Weber syndrome presented with severe headache and neck pain. Work-up revealed subarachnoid hemorrhage and evidence of multiple intracranial aneurysms. The patient was treated with open surgical clipping of his ruptured aneurysm and is currently doing well.

Technical note: Resolution of spontaneous electromyographic discharge following disk-space distraction during lateral transpsoas interbody fusion.

Purpose: The lateral transpsoas interbody fusion (LTIF) is an increasingly popular minimally invasive technique for lumbar interbody fusion. Although a posterior approach to the lumbar spine has traditionally been favored for the treatment of canal stenosis and neural foraminal stenosis, a growing body of evidence suggests that indirect decompression of the spinal canal and neural foramen can be achieved using a lateral transpsoas approach to the lumbar spine. We present 2 cases that may suggest a role for spontaneous electromyography (s-EMG) monitoring in assessing the adequacy of decompression during LTIF.
