... Abstract A great variety of thrombotic and nonthrombotic events may complicate all types of vascular access (VA) procedures. Thrombotic events are the most frequent complication, caused by stenoses in various locations, representing a common problem for arteriovenous fistulas (AVFs...

... Abstract Gamma Knife radiosurgery (GKRS) of cerebral arteriovenous malformations (AVM) is an accepted treatment option that has been performed for more than 40 years. The goal of AVM GKRS is nidus obliteration to eliminate the risk of intracranial hemorrhage while minimizing the risk of short...

... Abstract Intracranial dural arteriovenous fistulas (DAVFs) are abnormal arteriovenous connections within the dura, in which meningeal arteries shunt blood directly into the dural sinus or leptomeningeal veins. Among all the treatment options for the treatment of DAVFs, stereotactic radiosurgery...

... Abstract Background: An arteriovenous fistula (AVF) is considered the gold standard modality of vascular access (VA) for maintenance hemodialysis (HD) because of its superior patency, few complications, provision of high quality of life, and low risk of patient mortality. The rapid growth...

... Abstract Brain arteriovenous malformations (AVMs) are focal neurovascular lesions consisting of abnormal fistulous connections between the arterial and venous systems with no interposed capillaries. This arrangement creates a high-flow circulatory shunt with hemorrhagic risk and hemodynamic...

... Abstract The Furukawa experience treating 534 patients with cerebral arteriovenous malformations using gammaknife radiosurgery (GKRS) is summarized. By repeating radiosurgery for any residual nidus after the firstGKRS, the rates of cumulative complete obliteration 7 years after this initial...

... Abstract The early results of radiosurgery for dural arteriovenous fistula (DAVF) are reported. Thirteen cases of DAVF,9 males and 4 females, ranging in age from 39 to 74 years (mean 54.3), are presented. None underwentsurgical resection, but 7 of the 13 did receive embolization. DAVF locations...

... Abstract Arteriovenous fistula (AVF) has been recommended as the first choice for hemodialysisvascular access. This is supported by its superior patency and lower complication ratesover grafts and catheters. The increasing incidence of end-stage renal disease patients andconsequently higher...

... Abstract Histological, immunohistochemical and electron microscopic investigations were carriedout in a series of surgical pathology material that was removed from 7 patients. They were harboringcerebral arteriovenous malformations (AVMs) that had been previously treated withLeksell Gamma Knife...

... Abstract Introduction: Gamma Knife radiosurgery (GKR) is a standard treatment modality forintracranial arteriovenous malformations (AVMs). The efficacy and safety of this procedureis well accepted; yet, there is a relative lack of long-term studies in the literature to supportits low morbidity...

... Abstract Purpose: The Spetzler-Martin grade (SMG) accurately predicts outcome after surgicalresection of arteriovenous malformations (AVM); however, its application to radiosurgeryis limited because of insensitivity to AVM volume and location. Recently, aradiosurgical grading system...

... Abstract This chapter summarizes the diagnostic criteria and reliability of ultrasound detectionof intracranial dural arteriovenous fistulae (DAVF), carotid-cavernous fistulae (CCF), andparagangliomas. In arteries feeding DAVF ultrasound shows increased blood flow, systolicand, especially, end...

... Abstract Cerebral aneurysms and arteriovenous malformations (AVMs), including arteriovenousfistulae, are rather seldom investigated by means of transcranial color-coded duplex sonography(TCCS). Nevertheless, the continuous improvements in high-quality scanners, ultrasoundcontrast enhancers...
