Recent developments in cerebral angiography equipment and workstations have made it possible to produce clear angiograms useful images for neurosurgery. At our institution, we routinely perform aneurysm clipping after presurgical simulation using imaging data obtained three-dimensional angiography. This report describes the clinical significance of clipping.

We compared indocyanine green (ICG) and fluorescein angiography for evaluation of choroidal neovascularization (CNV). Cast preparations of CNV induced in monkey eyes by laser photocoagulation were correlated with ICG and fluorescein angiographies of the same CNV formations. Fluorescein angiography was more effective, in general, than ICG angiography in detecting CNV; however, CNVs with subretin...

Contrast-induced nephropathy (CIN) (known as contrast-induced acute kidney injury) occurs as a result of acute worsening of renal function following a procedure with administration of iodine contrasts agent and remains a substantial concern in clinical practices. The purpose of this study is to investigate the preventive effect of Pentoxifylline supplementation on reduction of CIN occurrence af...

iatrogenic coronary artery dissection during coronary angiography with or without rupture is a rare but feared complication . we herein report a case of iatrogenic left main coronary artery dissection in a 49-year-old female. admitted to our hospital with a recent history of severe hypotension, she develpled apnea during angiography. she was intubated  and resuscitated with an epinephrine infus...

fue to the importance of selecting imaging parameters in magnetic resonance brain angiography, this study was carried out to choose optimum theoretical and experimental parameters for improving image controast and resolution and achieve shorter imaging time for practical reasons.a 1.5t super conductive magnet mri with gradient power of 13 nt/m and larmour frequency of 63 mhz with imaging coli o...

OBJECT Whether routine intraoperative angiography is necessary for cerebral aneurysm surgery is currently under debate. In this study the authors prospectively assessed the cerebrovascular surgeon's accuracy in predicting the need for intraoperative angiography. METHODS Between January 2002 and January 2003, 200 consecutive patients (141 female and 59 male patients, mean age 52.8 years) with ...

BACKGROUND AND PURPOSE To determine the accuracy of multislice computed tomographic (CT) angiography in diagnosing total versus near occlusions of the internal carotid artery (ICA). METHODS Fifty-seven ICA total or near occlusions identified by catheter angiography were studied with multislice CT angiography 1 to 3 days after catheter angiography. CT angiography in diagnosing total versus nea...

conclusion coil embolization showed successful outcomes in the treatment of intracranial aneurysms with a low complication rate. results immediately after the procedure, the total occlusion was seen in 76 (86.4%), subtotal occlusion in six (6.8%), and partial occlusion in six patients (6.8%). there was no significant relationship between the aneurysm size, aneurysm neck size, and location of th...
