although arterialovenous fistulae (avf) is considered to be vital for chronic kidney disease (ckd) patients, but they may cause complications and problems. for instance they may fail soon after their creation. the most important cause of failure in these cases is intrafistula thrombus formation. whereas anti-platelet drugs are not routinely used after fistulae creation, we conducted this study ...

Dural arteriovenous fistulae of the transverse and sigmoid sinuses are highly variable in symptomatology and prognosis. However, we have identified a subgroup of patients who have a high risk of hemorrhage and dementia due to severe venous overload caused by high arterial flow into the fistulae and by occlusive changes of the transverse and sigmoid sinuses. Three representative cases selected f...

Intracranial dural arteriovenous fistulae (DAVF) are acquired fistulous communications between dural arterial branches and dural venous sinuses or cortical veins with the nidus located within the leaflets of the duramater. Dementia and Parkinsonism are amongst the rarest of clinical presentations in DAVFs and are important to diagnose early, being treatable with timely intervention. We present ...

Percutaneous venous and retrograde arterial catheterization by the Seldinger technique (Seldinger, 1953), or its modification, is a routine procedure in many cardiovascular diagnostic and research laboratories. The incidence and nature of complications after these procedures vary from one group of investigators to another. Reports and reviews of such complications are available (Peirce, I95I; P...

BACKGROUND Pulsatile tinnitus, unlike idiopathic tinnitus, usually has a specific, identifiable cause. Nonetheless, uncertainty often arises in clinical practice about the findings to be sought and the strategy for work-up. METHODS Selective literature review and evaluation of our own series of patients. RESULTS Pulsatile tinnitus can have many causes. No prospective studies on this subject...

Dural arteriovenous fistulae (DAVFs) in adults are generally regarded to be acquired lesions that may follow trauma, surgery, or thrombosis of a dural sinus (1, 2). Normal dural sinuses contain small arteriovenous anastomoses which do not appear to create any problem (3). In a setting of venous hypertension possibly in association with local angiogenic factors or congenital abnormalities of the...

BACKGROUND The European Best Practice Guidelines on Vascular Access propose magnetic resonance angiography (MRA) of dysfunctional dialysis fistulae and grafts if visualization of the complete arterial inflow and outflow vessels is needed. In a prospective multi-centre study we determined the technical success rate of complete vascular access tree depiction by digital subtraction angiography (DS...

Traumatic vertebral arteriovenous fistulae (AVFs) are relatively uncommon lesions that often follow penetrating wounds of the neck or iatrogenic arterial trauma [1-7]. Such posttraumatic single-hole fistulae differ from congenital arteriovenous malformations, which are composed of multiple communications between the cervical arteries and an abnormal vascular nidus [8] . True single-hole vertebr...
