Selective spinal cord angiography is the estab lished method for evaluating patients with vascular lesions of the cord. This technique is technically demanding , and the examination takes considerab le amounts of time and rad iation [1]. Digital subtraction angiography (DSA) with venous injections produces arterial images with dec reased patient risk . This procedure is also valuable in conjunc...

modalities for the evaluation of arterial vessels have been introduced. These include Color Doppler Ultrasound (CDU), spiral Computed Tomography (CT) and Magnetic Resonance [1-5]. The non-invasive character of these techniques represents a major advantage when compared with intra-arterial Digital Subtraction Angiography (DSA). These techniques are redefining the goals of DSA or “catheter based”...

Subarachnoid hemorrhage secondary to ruptured aneurysm is a critical clinical situation demanding a very skilled surgical and medical management. Until now cerebral digital subtraction angiography (DSA) has been used as the criterion standard for aneurysmal detection and planning of their microsurgical treatment. However, as the method for diagnosis of subarachnoid hemorrhage moved from lumbar ...

We present a method to automatically register 2D cerebral digital subtraction angiography (DSA) images to 3D-DSA volumes. The method can be used for validation of flow simulation results and surgery planning. The algorithm was tested on clinical studies of six patients.

We describe the 3D digital subtraction angiography (3D-DSA) image of extravasation from a rupturing aneurysm. This image clearly showed that the extravasation was coming from a pseudoaneurysm on an aneurysmal wall. To the best of our knowledge, this is the first demonstration of a 3D-DSA image of a rupturing aneurysm.

We report two cases in which volume subtraction three-dimensional CT angiography (VS-3DCTA) was used for cerebral aneurysm and vascular stenosis with intramural calcification. Case 1: VS-3DCTA with volume rendering clearly showed carotid cave aneurysm of the internal carotid artery. The location and size of the aneurysm was confirmed by digital subtraction angiography (DSA). In evaluation of th...

Spine vascular lesions like brain include spinal cord stroke, malformation such as venous or angioma, cavernous malformation, arteriovenous fistula. Embryogenesis of is the basic principle to understand spine. This study aims report serial cases with review lesions. MR angiography techniques contrast injection may reflect direction flow epidural veins describe site arterial feeders. Serpiginous...

BACKGROUND Epidural steroid injections (ESIs) are among the most common procedures performed in an interventional pain management practice. It is well known that tragic complications may arise from ESIs, most commonly those performed using a transforaminal approach. Digital subtraction angiography (DSA) has been hailed as a fluoroscopic technique that can be used to detect arterial placement of...

conclusions the advantages of dsa in fluoroscopy-guided transforaminal epidural block and nerve block are identification of the degree of appropriate contrast flow (epidural and nerve root sleeve) and the intravascular administration without overlapping radiodense structures. introduction most pain physicians know that fluoroscopy might improve the safety, accuracy, and efficacy of nerve block;...
