BACKGROUND AND PURPOSE Although digital subtraction angiography (DSA) is the reference standard for assessing carotid arteries, it is uncomfortable for patients and has a small risk of disabling stroke and death. These problems have fueled the use of spiral CT angiography and MR angiography. We prospectively compared elliptic centric contrast-enhanced MR angiography and spiral CT angiography wi...

Intraoperative angiography in cerebrovascular neurosurgery can drive the repositioning or addition of aneurysm clips. Our institution has switched from a strategy of intraoperative digital subtraction angiography (DSA) universally, to a strategy of indocyanine green (ICG) videoangiography with DSA on an as-needed basis. We retrospectively evaluated whether the rates of perioperative stroke, une...

PURPOSE To use a decision analytic model to determine the cost-effectiveness of performing diagnostic digital subtraction angiography (DSA), computed tomographic (CT) angiography, or magnetic resonance (MR) angiography or proceeding immediately to tentative percutaneous revascularization in patients suspected of having renovascular hypertension. MATERIALS AND METHODS With use of a Markov-Mont...

PURPOSE We preliminarily investigated the relevance of performing digital subtraction angiography (DSA) in addition to magnetic resonance angiography (MRA) in definition of ischemic stroke etiology in young patients. METHOD DSAs and MRAs from 17 young patients with nonlacunar ischemic stroke were blindly analyzed and their impact on stroke management was evaluated. RESULTS Etiologies were t...

During transcubital selective digital subtraction angiography (DSA), difficulties in catheterization of the supraaortic branches may arise as a result of improper catheter design (1, 2]. The catheters used for transfemoral cerebral angiography may not be suited for such studies , and for this reason we designed a new catheter for both transcubital aortic arch angiography and selective or semise...

BACKGROUND AND PURPOSE we compared the effectiveness of using computed tomographic angiography and venography (CTAV) with digital subtraction angiography (DSA) in young or nonhypertensive patients with acute spontaneous intracerebral hemorrhage. METHODS we prospectively recruited 109 young (age between 18 and 45 years) or nonhypertensive patients with acute spontaneous intracerebral hemorrhag...

BACKGROUND AND PURPOSE Both CT angiography and digital subtraction angiography are used to detect aneurysms in patients with subarachnoid hemorrhage. We examined a large multihospital data base to determine how practice is evolving with regard to the use of CT angiography and DSA in patients with ruptured cerebral aneurysm. MATERIALS AND METHODS The Premier Perspective data base was used to i...

BACKGROUND AND PURPOSE Four-section multisection CT angiography (MSCTA) accurately detects aneurysms at or more than 4 mm but is less accurate for those less than 4 mm. Our purpose was to determine the accuracy of 64-section MSCTA (64MSCTA) in aneurysm detection versus combined digital subtraction angiography (DSA) and 3D rotational angiography (3DRA). MATERIALS AND METHODS In a retrospective...

Postoperative angiography for aneurysm surgery is essential in identifying those aneurysms that have been inadequately clipped, allowing for additional corrective surgery. The current standard of reference for the postoperative evaluation of clipped aneurysms is digital subtraction angiography (DSA). However, DSA is an invasive method requiring arterial puncture and intraarterial catheter manip...
