Background and Importance: Symptomatic vasospasm is a well-known pathology associated with ruptured aneurysms. Nevertheless, this condition is rarely found as a result of skull base tumor removal. Case Presentation: We reported a new case of 40-year-old woman previously treated for a tuberculum and diaphragma sellae meningioma showing symptomatic vasospasm after twelve post-operative days wi...

AIM The aim of this study was to evaluate transauricular digital subtraction angiography (DSA) as an alternative to conventional intra-arterial DSA for rabbit abdominal aortic aneurysm (AAA). MATERIALS AND METHODS AAA models were created in 8 New Zealand white rabbits by sewing vein patch. The diameters of aortic arteries were measured by DSA via ear vein and ear central artery. The common ca...

This study aimed to compare the clinical value of carotid ultrasound and digital subtraction angiography (DSA) for artery stenosis in patients with cerebral infarction. Sixty infarction underwent DSA. Carotid stenosis, degree (mild, moderate, severe, occlusion), plaques were recorded compared. rate was 96.67 % (58/60) 91.67 (55/60) on DSA ultrasound, respectively, difference not statistically s...

BACKGROUND AND PURPOSE This study was undertaken to assess the utility of contrast-enhanced MR angiography at 6 months after endovascular treatment of intracranial aneurysms with Guglielmi detachable coils. METHODS Contrast-enhanced MR angiography was performed in 47 patients at 6 and 12 months after endovascular treatment of intracranial aneurysms (48 aneurysms). Digital subtraction angiogra...

A gold standard of cerebral vessel imaging remains the digital subtraction angiography (DSA) performed in three projections. However, in specific clinical cases, many additional projections are required, or a complete visualization of a lesion may even be impossible with 2D angiography. Three-dimensional (3D) reconstructions of rotational angiography were reported to improve the performance of ...

Intraarterial digital subtraction angiography (DSA) in two patients with spinal dural arteriovenous fistulas demonstrated the major feeding arteries and the venous drainage of the respective malformations. However, the dural component of the malformations--which distinguishes them from intradural malformations--could not be recognized, nor was normal cord vasculature demonstrated. In a patient ...

Peripheral vascular disease (PVD) has an age-adjusted prevalence of 12% in the United States, causes significant morbidity and is associated with excess cardiovascular mortality. Contrastenhanced magnetic resonance angiography (CE-MRA) often substitutes for the more invasive ―gold standard‖ procedure of digital subtraction angiography (DSA). Given the frequency of renal functional impairment in...

We observed 102 patients suspected of having pulmonary emboli (PE) who underwent ventilation-perfusion (V/Q) lung scintigraphy and IV digital subtraction angiography (DSA). Only five DSA studies were inadequate for interpretation. In 81 of the remaining 97 patients (83.5 percent) the results of both studies correlated regarding the probability of PE. In 50 patients the results of both studies w...

AIM To evaluate the clinical feasibility of a newly developed, fully automatic vessel segmentation software with automatic structured bone elimination (ASBE) using graph-matching and subvoxel analysis. MATERIALS AND METHODS Dual energy computed tomography angiography (DECTA) data of 108 vessel segments were evaluated using the ASBE software and a commercial software against the digital subtra...

An accurate morphological assessment of blood vessels and their relationship with interventional devices is essential in the management of vascular lesions, and digital subtraction angiography (DSA) has had a central role in the deployment of interventional procedures. The introduction of three-dimensional rotational angiography (3D RA) and flat panel detector technology has further contributed...
