“…Unlike subjective tinnitus, it arises from a mechanical somatosound. And consideration of differential diagnosis for pulsatile tinnitus is important because there is an array of causes that can be identifiable and treatable easily, and many of them are vascular origin problem [ 8 ]. DAVF are abnormal arteriovenous shunts between dural arteries and venous sinuses and around the meningeal/cortical venous vessels [ 8 ].…”

“…And consideration of differential diagnosis for pulsatile tinnitus is important because there is an array of causes that can be identifiable and treatable easily, and many of them are vascular origin problem [ 8 ]. DAVF are abnormal arteriovenous shunts between dural arteries and venous sinuses and around the meningeal/cortical venous vessels [ 8 ]. Although their etiology is not clearly understood, DAVF have been found in association with venous thrombosis, intracranial surgery, tumor, trauma and congenital anomalies.…”

“…Imaging modalities for the patients with pulsating tinnitus are necessary to detect the potentially treatable vascular etiologies, and they include computed tomography angiography (CTA), non-enhanced CT of the temporal bone, MRI and MRA, catheter angiogram [ 9 ]. CTA is considered as initial imaging examination of choice, because it provides a robust assessment of various intra- and extratemporal vascular pathologies, including DAVF, as well as an excellent description of the bony anatomy of the temporal bone [ 8 ]. Temporal bone CT may represent the transosseous vascular shapes, which are highly specific for the diagnosis of DAVF [ 9 ].…”

Dural arteriovenous fistula (DAVF) have been treated by transarterial or transvenous embolization, surgery, and radiosurgery. Besides these treatment options, the external compression technique is a non-invasive, low-cost form of treatment. This article reports that a 60-year-old man with DAVF between multiple arterial branches and transverse/sigmoid sinus was treated by repeated external manual compression method.

Objective Time resolved contrast enhanced magnetic resonance angiography (TR CEMRA) is commonly used to non-invasively characterize vascular malformations. However, the spatial and temporal resolution of current methods often compromises the clinical value of the exams. Constrained reconstruction is a temporal spatial correlation strategy that exploits the relative sparsity of vessels in space to dramatically reduce the amount of data required to generate fast high resolution TR CEMRA studies. In this report we use a novel temporal spatial acceleration method termed HYPRFLow to diagnose and classify dural arteriovenous fistulas (DAVFs). Our hypothesis is that HYPRFLow images are of adequate diagnostic image quality to delineate the arterial and venous components of DAVFs and allow correct classification using the Cognard system. Subjects and Methods 8 patients with known DAVFs underwent HYPRFlow imaging with isotropic resolution of 0.68 mm and temporal resolution of 0.75 s and 3D Time of Flight MRA (3DTOF). 3DTOF images and HYPRFLow images were evaluated by 2 readers and scored for arterial anatomic image quality. DSA was available for comparison in seven subjects and for these patients each DAVF was classified according to the Cognard system using HYPRFlow and DSA exams. DSA was considered the reference exam or gold standard. Results HYPRFlow imaging classification was concordant with DSA in all but one case. There was no difference in the arterial image quality scores between HYPRFlow and 3DTOF MRA (95% CI). Arterial to venous separation was rated excellent (n=3), good (n=4) or poor (n=1)and arteriovenous shunting was easily appreciated. Undersampling artifacts were reduced by using a low pass filter and did not interfere with the diagnostic quality of the exams. Conclusion HYPRFlow is a novel acquisition and reconstruction technique that exploits the relative sparsity of intracranial vessels in space to increase temporal and spatial resolution and provides accurate delineation of DAVF vasculature.
