Both transfemoral and transbrachial arterial routes could not be used in this 5-year-old girl with PHACE syndrome, as a result of aortic disruption and aneurysmal dilation, as well as small loops of the proximal portion of bilateral subcutaneous veins. Through the patent foramen ovale, the catheter was then delivered to the left ventricle and then to the ascending aorta.

OBJECTIVE Catheter-based cerebral angiography is commonly used for neurovascular assessment in children. METHODS Relevant clinical results were retrospectively collected for 587 consecutive cerebral angiography procedures performed in 390 children from March 2002 to March 2020. In univariate study using the two-tailed Fisher exact test and in multivariate analysis using multiple logistic regression with bidirectional elimination based on the Akaike information criterion, correlations between risk factors and complications were characterized. Female sex and a history of hypertension or ischemic stroke were correlated with an elevated risk of complications, although femoral artery access was correlated with a reduced risk of complications. Pediatric cerebral angiography was found to have a low incidence of acute or persistent complications. CONCLUSIONS Children who were female and those with a history of hypertension or ischemic stroke were prone to complications, according to researchers, who were obese, while femoral access decreased the risk of complications.

Object The therapeutic potential for cerebral angiography in young children is increasing. Methods The authors reviewed reports for 309 consecutive cerebral angiograms performed in 87 children younger than 36 months of age from 2004 to 2010 at a single institution, which were analyzed by the authors. Results The patient population consisted of 40 boys and 47 girls, with mean age of 14. 36 months and mean weight of 10. 8 kg. 7 cases of contrast allergy or bronchospasm, 1 groin hematoma, and 1 transient femoral artery occlusion were among the nonneurological disorders detected in comparison to nonneurological disorders: 2. 9%, 7 cases of contrast allergy or bronchospasm, 1 groin hematoma, and 1 transient femoral artery occlusion compared to 0. 9. The rate of radiographic problems was 1. 3%: 1 case of acute asymptomatic intraarterial dissection and 3 cases of asymptomatic vasospasm. For 33. 3 percent of patients with no signs of ischemia, postprocedural MRI was performed. Conclusions The incidence of pneumonia in young children in young children is similar to those reported for older children and lower than adult averages.

Object Description In the resection of adult arteriovenous malformations, cerebral intraoperative angiography has been used. In a small number of children, studies have described experiences with intraoperative angiography. The aim of the investigation was to determine the use of cerebral intraoperative angiography in children undergoing AVM resection. Methods The Children's Hospital of Philadelphia between 2008 and 2012 conducted a retrospective review of all patients undergoing cerebral AVM resection with intraoperative angiography. A total of 21 intraoperative angiography procedures were performed in 18 AVM resections in 17 patients. 1. 1 years ago, the median follow-up time from intraoperative angiography to the most recent postoperative angiography was 1. 1 years. Conclusions Intraoperative angiography is a safe and appropriate substitute for surgical management of cerebral AVMs in the pediatric population.

Cerebral cavernous malformations have been attributed to ostensibly occult malformations with low blood supply. 2,3 In the event of a prospective venous sacrifice, it could be helpful to distinguish intraoperatively between normal veins and DVA draining veins. 1,2 For these reasons, we decided to use ICG video angiography in this patient.

Next to image anatomical structures, it is also possible to perform FD CT perfusion imaging of the brain by means of cerebral blood volume or pooled blood volume mapping during steady state contrast research. In this paper, we review the literature on the use of FD CT PBV mapping in patients and show its current use in interventional neuroradiology diagnosis and therapy monitoring.

OBJECTIVE The study was designed to determine the diagnostic accuracy of 320-detector row nonsubtracted and subtracted volume CT angiography in finding small cerebral aneurysms in patients of little cerebral aneurysms when compared to 3D digital subtraction angiography. METHODS Six hundred sixty-two patients underwent 320-detector row VCTA and 3D DSA for suspected cerebral aneurysms. Independently reviewed VCTA and 3D DSA photographs by Five neuroradiologists independently. RESULTS CHANGES RESULTS 90 of 662 patients were found in 98 small cerebral aneurysms, according to 3D DSA images. There was no difference in accuracy between subtracted VCTA and 3D DSA. However, nonsubtracted VCTA had less sensitivity than 3D DSA and subtracted VCTA, but not subtracted VCTA. CONCLUSIONS The subtracted 320-detector row of VCTA is sufficiently accurate to replace 3D DSA in the diagnosis of small cerebral aneurysms. Smaller internal carotid artery aneurysms adjacent to the skull base were found to be lower than that of subtracted VCTA and 3D DSA, particularly in the assessment of small internal carotid artery aneurysms adjacent to the skull base.

This study was done to determine whether quantitative hemodynamic evaluation by using MR angiography could stratify CHS risk stratification. paraphrasedoutput:METHODS In this prospective research, patients with internal carotid artery stenosis were randomly selected for pre- and postoperative quantitative phase contrast MR angiography. RESULTS Twenty-five of 153 patients with CEA for ICA stenosis were randomly selected for pre- and postoperative QMRA. Both in the ICA and MCA s, the mean flow increases in the patients with CHS were significantly higher than those without CHS. The best clinical risk factors for CHS, according to female sex and a low preoperative diastolic blood pressure, were apparent risk factors for CHS, though flow variations and absolute postoperative flow values in the ipsilateral ICA and MCA were identified as potential radiological predictors for CHS. CONCLUSIONS TEBRAL blood flow in the ipsilateral ICA and MCA as assessed by QMRA has dramatically increased after CEA.

paraphrased hemorrhage in patients with poor-grade aneurysmal subarachnoid hemorrhage are reported. The authors compared the clinical results of the therapy to a new poor-outcome imaging predictor that caused impaired cerebral perfusion on initial CT angiography. METHODS THE authors reviewed the treatment results of 148 patients with poor-grade aSAH treated at a joint tertiary referral center between 2007 and 2016. Patients with the u201cvenous delayu201d phenomenon on initial CTA had been identified. At the 3rd month after a SAH, the outcome tests used the modified Rankin Scale. RESULTS Compared to previously established outcome predictors, the venous delay effect on initial CTA was found to be the greatest relationship with posttreatment outcomes on both univariable and multivariable analysis. CONCLUSIONS The venous delay in the first CTA may be a predictor of poor functionality and may help with decision making in cases treating patients with poor-grade aSAH.
