The development of Computed Tomography and Magnetic Resonance has reduced the diagnostic role of Digital Subtraction Angiography (DSA) in the neuroradiological evaluation of intracranial tumors. DSA is currently an important pre-surgical examination, able to offer important information regarding the type and the entity of neoplastic vascularization. Moreover the development of endo-vascular interventional practices (pre-surgical embolization of meningiomas and endo-arterious chemotherapy of gliomas) has widened the applications of angiography.

Demonstrated in this report is an example of arteriovenous shunting and early venous filling in an area of cerebral infarction recorded on digital subtraction angiography. This angiographic appearance is largely of historical interest given the current use of sectional imaging (CT and MR) and altered role of angiography in the imaging of stroke, but should nevertheless still be considered amongst the differential causes of cerebral arteriovenous shunting.

Abstract Advances in digital subtraction angiography (DSA) have allowed the evaluation of a number of pathological conditions involving the extra-and intracranial vasculature. In addition to its role in diagnosis. DSA has been used for the postoperative assessment of endarterectomy, aneurysm clipping, and vascular bypass and for the follow-up of arteriovenous fistulas or malformations. This paper describes the theory and anticipated improvements in the digital processing of radiological information and presents our initial assessment of its clinical utility.

Abstract Background Cervicofacial vascular lesions are one of the most challenging diseases managed by intervention radiologists and specialized surgeons. These lesions were diagnosed to be vascular in origin by other imaging techniques such as Duplex and/or magnetic resonance imaging (MRI). All patients underwent computed tomographic angiography (CTA) to confirm the diagnosis as well as to decide the most effective choice of management based on multidisciplinary team (MDT). Then, Digital subtraction angiography (DSA) was done as it is offering an accurate vascular map for the vascular lesions which is inevitable for successful super-selective endovascular embolization which can be done at same sitting. Small cases of arteriovenous malformations (AVMs) were sufficiently managed by only embolization, whereas cases of adequately embolized large AVMs as well as juvenile nasopharyngeal angiofibroma (JNA) cases were followed by surgery with the advantage of less blood loss and decreasing operation time as well as complications. This prospective study was done to highlight the role of combined CTA and DSA in cervicofacial vascular lesion management. Results Twenty patients were included in our study: 16 patients were males, and 4 were females; 17 of them were under 40 years, and three were above 40 years. Preoperative embolization was done in 12 patients, which were all the cases of JNAs and large AVMs. Four patients were managed by only embolization as a definitive treatment. Complete technical success rate was about 94%, while only 6% (single case) of the partial technical success rate which was due to a very small accessory feeder that could not be catheterized even with repeated trials. Conclusions Combined CTA and DSA is the cornerstone for managing vascular lesions in the cervicofacial region, which necessitates a MDT to decide the most beneficial and least complicated way for management.
