A 67-year-old woman presented with an 8-mm-diameter pulsatile mass in her right forearm. The mass had been present for a year and has increased in size. She had a negative relevant medical history and no history of trauma, intervention, or venipuncture on the right arm. She did not complain of pain, numbness, or functional deficit of the arm or hand. Computed tomography angiography revealed a s...

BACKGROUND AND PURPOSE Long-term patency in untreated experimental aneurysms represents a critical attribute of any system proposed for the testing of aneurysm occlusion devices. Our purpose was to evaluate the long-term patency in elastase-induced saccular aneurysm models in rabbits. METHODS Serial intravenous digital subtractive angiography (IVDSA) was performed in 20 elastase-induced saccu...

BACKGROUND AND PURPOSE The endovascular treatment (EVT) of intracranial aneurysms is no more limited by the presence of a branch at the neck or by the neck width. Saccular aneurysms with a branch arising from the sac, however, are mostly candidates for surgery rather than embolization. We prospectively evaluated the feasibility and safety of the EVT in such cases. METHODS Between May and Nove...

Vestibular-evoked myogenic potentials (VEMPs) are proposed as a reliable test to supplement the current vestibular test battery by providing diagnostic information about saccular and/or inferior vestibular nerve function. VEMPs are short-latency electromyograms (EMGs) evoked by high-level acoustic stimuli and recorded from surface electrodes over the tonically contracted sternocleidomastoid mus...

Adult bullfrog were given single intraotic injections of the aminoglycoside antibiotic gentamicin sulfate and sacrificed at postinjection times ranging from 0.5 to 9 days. The saccular and utricular maculae of normal and injected animals were examined in wholemount and cross-section. Intraotic 200 microM gentamicin concentrations resulted in the uniform destruction of the hair bundles and, at l...
