Unexpected bleeding from the dural sinus can sometimes occur when performing a dural opening during microvascular decompression. We conducted dural opening safely by performing indocyanine green (ICG) videoangiography before making a dural incision. We introduce two specific cases in which surgery was performed to treat a trigeminal neuralgia. In both cases, a small craniectomy was performed in...

The dura mater is a vascularized membrane surrounding the brain and is heavily innervated by sensory nerves. Our knowledge of the dural vasculature has been limited to pathological conditions, such as headaches, but little is known about the dural blood flow regulation during behavior. To better understand the dynamics of dural vessels during behavior, we used two-photon laser scanning microsco...

BACKGROUND AND PURPOSE Basilar trunk aneurysms (BTAs), defined as aneurysms distal to the basilar origin and proximal to the origin of the superior cerebellar artery, are rare and challenging to manage. We describe the natural history and management in a consecutive series of BTAs. METHODS Between 2000 and 2013, 2522 patients with 3238 aneurysms were referred to our institution for aneurysm m...

An unusual case of a 23-year-old woman was referred to our hospital with a palpable aortic pulse in the epigastric area (Picture 1 white arrow). Her medical history revealed dilation of the ascending aorta, hind foot deformity, pectus excavatum, dural ectasia, scoliosis, skin striae and mitre valve prolapse typical signs associated with Marfan’s Syndrome (1). Recent CT angiography findings of t...

Pulse-synchronous tinnitus suggests a vascular etiology and is deemed rare by the otologic literature. During the period 1978-1985 we evaluated 20 patients with the sole or initial complaint of pulsatile tinnitus. Fourteen patients had objective pulsatile tinnitus, perceived by the patient and the examiner alike, and 6 had subjective pulsatile tinnitus, perceived by the patient only. Angiograph...

A 53-year-old man presented with a 5-month history of visual loss in his left eye. Visual acuity could be corrected to 20/20 with an increased hyperopic correction. Dilated funduscopy showed faint choroidal folds and elevation of the left optic disc. The coronal view of T2-weighted magnetic resonance imaging demonstrated a fluid-filled dilated sheath surrounding normal optic nerves. General phy...

background: according to the angiographic findings, 3%-8% of atherosclerotic coronary artery patients suffer from coronary artery ectasia (cae). we conducted this study to estimate the prevalence of cae among patients who underwent angiography and compared this group with those patients without cae and atherosclerosis in terms of common coronary heart disease (chd) risk factors. methods : this ...

a 22 year old male referred with palpitation. general appearance and physical exam impressed us in that the patient has marfan syndrome. cardiac catheterization showed diffuse arterial ectasia. we found no previous report of this generalized diffuse ectasia.

Metrizamide computed tomographic myelography demonstrates well: partial- and full-thickness diastematomyelia; the presence, shape, and (a)symmetry of the two hemicords; focal persistence of two anterior spinal arteries, one supplying each hemicord; the single or double subarachnoid space(s), arachnoid tubes, and dural tubes which encompass the hemicords; the dural septum formed by the medial wa...

background: spinal anesthesia is usually applied for urologic surgeries. postdural puncture headache (pdph) is among common complications which has not been reduced during last years despite all advances in the field of medicine. therapeutic effects of conventional therapy (paracetamol and novaphen) are being compared to intravenous meperidine in patients suffering from pdph. methods: one hundr...
