We report the first case of de novo formation a small 4- × 3-mm symptomatic aneurysm with subsequent subarachnoid haemorrhage (SAH) within 15 days. A pre-existing was excluded by magnetic resonance angiography, as well conventional angiography. In this case, there no history SAH, which is in contrast to other reported cases aneurysms that developed after previous rupture.

BACKGROUND To identify patients with spontaneous subarachnoid hemorrhage for whom CT angiography alone can exclude ruptured aneurysms. METHODS An observational retrospective review was carried out of all consecutive patients with non-traumatic subarachnoid hemorrhage who underwent both CT angiography and catheter angiography to exclude an aneurysm. CT angiography negative cases (no aneurysm) ...

Objective: Congenital heart disease is the most common congenital anomaly. Early diagnosis and timely intervention are important in disease. The aim of this study to share our experience follow-up results diagnostic interventional angiography procedures performed center.
 Materials Methods: retrospective included patients who underwent catheter clinic between July 2018 October 2021.

In recent years MR Angiography allowed to assess blood vessels and flow in a non-invasive way. The aim of our work was illunstrate modern technique, the 4D Iterative reconstruction Time resolved angiography With Interleaved Stochastic Trajectories (IT-TWIST), capable generate angiograms with high spatial temporal resolution, providing multiple continuous post-contrastographic sets images. Techn...

PURPOSE To evaluate magnetic resonance (MR) angiography and MR imaging in assessment of moyamoya disease. MATERIALS AND METHODS The cases of 26 patients with moyamoya disease were evaluated prospectively. After three-dimensional time-of-flight 1.5-T MR angiography and MR imaging, images were evaluated in blinded separate interpretation. RESULTS MR angiography and MR imaging accurately depic...

UNLABELLED Computed tomographic (CT) angiography has become a valuable diagnostic technique prior to lower extremity arterial reconstruction. The purpose of this study is to evaluate its accuracy, compared to conventional angiography for planning lower limb revascularization procedures. PATIENTS AND METHODS A prospective study was performed on all patients who underwent lower extremity arteri...

PURPOSE To perform a systematic review to determine the accuracy of computed tomographic (CT) angiography, magnetic resonance (MR) angiography, and transcranial Doppler ultrasonography (US) in depicting intracranial aneurysms. MATERIALS AND METHODS A 1988-1998 literature search for studies with 10 or more subjects in which noninvasive imaging was compared with angiography was undertaken. Stud...

BACKGROUND AND PURPOSE Multi-section CT has great potential for use in vascular studies. Our purpose was to determine the accuracy of multi-section CT angiography in detecting cerebral aneurysms compared with digital subtraction angiography or surgery. METHODS One hundred consecutive patients who underwent multi-section CT angiography and either digital subtraction angiography or surgery were...

PURPOSE To determine the usefulness of CT angiography in the setting of suspected acute subarachnoid hemorrhage or intracranial aneurysm. METHODS We prospectively studied 68 patients suspected of having subarachnoid hemorrhage or an intracranial aneurysm with noncontrast CT of the head followed immediately by contrast-enhanced helical CT of the circle of Willis with three-dimensional reconstr...
