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 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
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
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
An arteriovenous fistula is a rare complication of ruptured abdominal aortic or iliac artery aneurysms (IAAs). Its clinical symptoms depend on its size, with signs of heart failure dominating if the fistula is large. Herein, we present a case of arteriovenous fistula with an unusual presentation. An
Local complications of arterial puncture include hematoma, pseudoaneurysm and formation of arteriovenous fistula (AVF). The latter could cause ischemia of the particular extremity or can be hemodynamically significant especially in patients suffering from congestive heart failure. We report a case
Medullary edema with enhancement is rarely reported at initial MR imaging in intracranial dural arteriovenous fistulas. We report a series of 5 patients with dural arteriovenous fistulas, all of whom demonstrated a characteristic pattern of central medullary edema and medullary enhancement at
Apparent diffusion coefficient (ADC) values at magnetic resonance imaging (MRI) are useful to distinguish vasogenic and cytotoxic edema due to cerebovascular diseases. Dural arteriovenous fistulas (DAVFs) with retrograde leptomeningeal venous drainage may cause cerebral edema by venous congestion.
OBJECTIVE
To analyse the course of upper limb edema in patients with an arteriovenous fistula used for dialysis and to analyse the available therapeutic options.
METHODS
Retrospective study of patients with this type of edema, who were treated in our institution from 1992 to 1996.
METHODS
Seven
A 52-year-old woman after renal transplantation developed unilateral pleural effusion as well as a massive edema of the upper limb, breast, and face as a complication of the subclavian vein catheterization and arteriovenous fistula for hemodialysis. We revealed that impaired venous drainage due to
A 38-year-old woman with end-stage kidney disease presented with a pleural effusion and profound edema of the ipsilateral arm and breast. A patent hemodialysis arteriovenous fistula access was present in the involved extremity. Brachiocephalic vein stenosis, as a result of previous dialysis catheter
We report a case of persistent tense edema of the upper extremity following the surgical creation of an arteriovenous fistula for hemodialysis access. This was the result of poor venous return secondary to thrombosis of the subclavian vein. The thrombosis occurred after previous subclavian vein
Fetal heart failure and hydrops fetalis may occur due to systemic arteriovenous fistula because of increased cardiac output. Arteriovenous fistula of the central nervous system, liver, bone or vascular tumors such as sacrococcygeal teratoma were previously reported to be causes of intrauterine heart
Spinal dural arteriovenous fistulas (SDAVFs) are the most common type of spinal arteriovenous malformations; they frequently cause progressive myelopathy, including gait disturbances and sensory disorders.We report a rare case of a middle-aged man who We report a patient with a petrosal arterio-venous dural fistula draining into the ponto-mesencephalic and medullary venous systems presenting with edema of the brain stem and complete reversal of magnetic resonance imaging (MRI) abnormalities after combined endovascular and surgical treatments.
