BACKGROUND AND PURPOSE Multiple studies have shown that negative computed tomographic angiograms (CTAs) are reliable in excluding aneurysms in patients with isolated perimesencephalic subarachnoid hemorrhage (pSAH). We evaluate the use of digital subtraction angiography versus CTA for initial diagnosis and of angiographic follow-ups in patients with pSAH by performing an institutional analysis ...

To present a retrospective post-pancreaticoduodenectomy case series that had sentinel bleeding after pancreaticoduodenectomy and to evaluate the necessity and safety of prophylactic embolization. Fifteen post-pancreaticoduodenectomy patients with sentinel bleeding after pancreaticoduodenectomy were included in this study. Digital subtraction angiography was performed 6 hours after sentinel blee...

BACKGROUND AND PURPOSE The purpose of this study was to determine the utility of postcontrast susceptibility-weighted MRI (PCSWI) in the evaluation of vascular malformations of the brain (BVM). METHODS We retrospectively evaluated PCSWI and digital subtraction angiography data from 16 consecutive patients with known or suspected BVM, which had been entered into a prospectively maintained data...

BACKGROUND AND PURPOSE Recanalization rates after the intravenous (IV) recombinant tissue plasminogen activator (rt-PA) treatment have been poorly studied in acute stroke. METHODS CT angiography was performed before IV rt-PA in all patients and digital subtraction angiography was undertaken for intra-arterial thrombolysis in cases of no improvement after rt-PA infusion. RESULTS Forty-five p...

Purpose: This paper aims to realize an analysis of available radio-imaging methods for outlining various forms of pulmonary embolism (acute or chronic) with highlights on the semiology and adequate medical indications. Methods: There are several types of radiological examinations used in the evaluation of pulmonary embolism such as perfusion scintigraphy V/Q, digital subtraction angiography, co...

Although conventional or digital X-ray angiography is still the standard method in the diagnosis of intracranial vascular abnormalities, MR imaging is gaining a more prominent role in this respect. MR angiography is a new method of vascular imaging that provides projection images resembling conventional angiography [1 , 2]. We present the MR angiographic findings in two patients with primitive ...
