The evidence for the existence of secondary endolymphatic hydrops in patients with perilymphatic fistulas is reviewed and the indications for treatment of such hydrops in patients with fistulas are discussed. The indications for and results of combined fistula repair by middle ear exploration and
Presented are ten cases of patients with perilymphatic fistula and/or endolymphatic hydrops who had tinnitus as a major complaint. Tinnitus and its degree of severity often correlate closely with the state of health or hydrodynamic integrity of the inner ear, as these cases illustrate.
Dural arteriovenous fistulas of the craniocervical junction are rare but the most dangerous of spinal fistulas. The concurrent brainstem edema has been attributed to increased pressure within the venous outflow of the brainstem and upper cord, but the differential diagnosis of A series of 15 ears were explored for perilymph fistulas. Fifteen fistulas were found in 13 ears. Two cases are presented which developed hydrops-like symptoms only after closure of their fistulas. Closure of the other patients' fistulas was successful in relieving vertiginous symptoms, although
CONCLUSIONS
SDAVFs cause hypertension and hence outflow obstruction in the perimedullary venous system resulting in swelling and edema of the cord followed by dysfunction. Clinical presentation is usually with gradual progressive paraparesis, numbness, and sphincter problems. MR imaging typically
OBJECTIVE
To present a case report on a patient with retinal complications from a carotid-cavernous fistula.
METHODS
Observational case report.
RESULTS
A 26-year-old patient sustained head trauma following a motorcycle accident. Examination and retinal imaging demonstrated a venous stasis
OBJECTIVE
We investigated whether pial venous reflux (PVR) is associated with hemorrhage or edema in dural arteriovenous fistula (DAVF).
METHODS
We evaluated the association of hemorrhage or edema with the occurrence of PVR or cortical venous reflux (CVR) in 222 patients with DAVF. We determined
The authors report a very rare presentation of traumatic carotid-cavernous fistula (CCF) with extensive edema of the basal ganglia and brainstem because of an anatomical variation of the basal vein of Rosenthal (BVR). A 45-year-old woman was admitted to the authors' institution for left hemiparesis,
We have tested the hypothesis that the cause of cochlear dysfunction associated with perilymphatic fistula (PLF) is closely related to endolymphatic hydrops (ELH). Using guinea pigs, we studied the tone-burst elicited compound action potential (CAP) and its modulation as caused by a 50 Hz biasing
Aortocaval fistula (ACF) is a rare complication of abdominal aortic aneurysm (AAA), and its preoperative diagnosis is often difficult. A 71-year-old woman was admitted to our hospital due to unilateral leg edema. Abdominal computed tomography (CT) showed an abdominal aortic aneurysm (AAA), a common
BACKGROUND
Massive ipsilateral edema in patients with cerebral dural arteriovenous fistula (DAVF) is poorly documented. The present study better characterizes this condition through assessment of venous anatomy and potential underlying mechanisms.
METHODS
One hundred and two consecutive patients
Brainstem edema caused by traumatic carotid-cavernous fistula (TCCF) is rare, and there is little information available regarding its clinical characteristics. The present report describes the case of a 51-year-old man with TCCF, who presented with right exophthalmos and intracranial bruit for 1
The authors report a rare case of pial single-channel arteriovenous fistula presenting with significant brain edema. A 51-year-old woman was admitted with a 5-day history of headache and nausea, followed by consciousness disturbance. Computed tomography showed cerebellar swelling with obstructive
Cochlear hydrops was produced either by injecting artificial perilymph into the subarachnoid space or by sucking perilymph through the round window membrane. The animals were either vitally fixed immediately or kept alive for 1 to 3 months before fixation. Conventional celloidin embedding method was
The endolymphatic-perilymphatic shunt operation between the scala media and scala tympani was performed in 22 guinea pigs with endolymphatic hydrops induced by the silver nitrate injection method 2 months before the operation. Two (n = 10), 7 (n = 6), and 28 (n = 6) days after the operation, the
