ABSTRACT
Dural arteriovenous fistulas (dAVF) are rare vascular malformations accounting for only 10-15% that may lead to life threatening deficits due to hemodynamic changes in blood supply and pressure conditions. We present a 64-year old patient who was admitted with disorientation and aphasia. Following images confirmed an infratentorial dural fistula draining into the straight sinus. Additional findings were progressive thrombosis of the straight sinus, microbleedings and bithalamic edema due changes in hemodynamic conditions and venous congestion. Microsurgery was performed. After treatment improvement in clinical condition was observed and the venous congestion was regressive. Hemodynamic changes due to infratentorial dAVFs may lead to bleedings in deep regions and worsening of clinical condition fastly. Treatment requires carefully planning and visualization of angioarchitecture. Symptoms and hemodynamic changes are reversible after treatment, which are essential for treatment decisions.
