 Today everyone role of I'll be talking about my study role of MD sitting evaluation of vasculopathy is causing CNS disorders in pediatric and in the patients. Introduction in children and in girls most of the stokers due to cardiac stroke and other matters diseases which but which it less than in the older age group in this presentation. I'm going to talk only about the aneurysmal lesions and all of them are diseases causing stroke. And I'm going to do some open for a 10 to 15% of hemorrhagic strokes. I'm going to talk about a 10 to 15% in other than 20 to 25% in pediatric patients on the matters of the vessel diseases can present as a mildly take to the stroke or ICH and it may be difficult to diagnose without imaging and I'm imaging also provides some lead to the clinician regarding any further evaluation like targeted biopsy or any biomarkers like CSF aspiration etc. SAH due to an assessment procedure can be diagnosed and treated clinically but use of CTA infant diagnosing and treating it to prevent further episodes, other ways which will lead to further morbidity and SCVM mortality rate. Ames and objectives process the use of MDCT in diagnosing vessel disorders to establish the effectiveness of MDCT as an imaging tool for the intracranial and extracranial vessels to determine the spectrum of radiological characteristics of different etiologies which leads to stroke whenever possible. Materials and methods, the study was done in Osmane General Hospital in patients presenting with the symptoms of stroke. By this 26 patients were included in the study who were showing intracranial and extracranial disorders. The CTA study was done in 128 slides standard. Initial non-contrast CT was followed by CT angiography. CT angiography was done with the formation of 0.625 mm. For this 60 mm contrast was used which is injected at rate of 3 to 4 mm per second and followed by 30 mm swelling flesh. The observations were characterized based on the part of vessel in one extent of involvement territory of in case of aneurysm, narrowing down the location based on the location of ACH, then size, position and relation of the aneurysmal vessel which is needed for the intervention. And also in case of ABN, the study was also correlated with the DSA to identify the feeding artery, training veins and neunidus wherever possible. Inclusion criteria. Patients with the same symptoms of stroke. Exclusion criteria includes traumatic patients, intracranial SEL patients and the patients with chronic cerebral failure. Results of my study were 26 patients, 12 were in the pediatric age group and the rest 14 patients and the ambulance. Most of the lesions were seen in between the third to fourth decade. Davy fistul and malformation cases were further correlated with the DSA to correctly identify the vessel and arteries and feed the training veins and the aneurysm sizes. And in case of asculitis group, eye resolution MRI was not opted for the patients because of multiple episodes in the past. In the pediatric age group, five cases, four cases of mya-moya, three cases of tachycarditis was presented and one case from each of AB fistula, which is a pylabipistula, one case of focal cerebral artery opathy, primary senus agitase, sickle cell disease with multiple basal collaterals and one from tibium splitis. In the young adult age group, four were off from showing AB malformation, four of aneurysm, which is mostly in the fourth and fifth decade. Two cases of spinal dural AB fistula, which is seen after 40 years. Two cases of connective tissue disorder and asculitis, which is seen less than 40 years of age and two cases of tibium asculitis. Discussion. A study by Amad Abdel Etal on topic of imaging spectrum of senus asculitis, seen sickle angiography can be used to evaluate both the vessel walls and lumen. And it also showed vessel wall abnormalities when there is no luminal abnormalities, which is correlated with the conventional catheter angiography. And it also demonstrates there is in the presence of aneurysm, ticani, and also carried assessment of stenotic lesions in large vessels. Study by Tarasova Etal in a Moyamaya disease show, CT is sufficient for ischemic or a meningic stroke. And particularly, particularly, it is helpful in identifying occlusion of stenosis in large infectious patients. A study by Eric Etal in an AVM patients show, CT if timed properly can depict anitis, feeding arteries and draining wounds. And it is 90% sensitive in detection of AVMs compared to MRA, which was time off like MRA, which was only 74% sensitive. A study by Mahesh V. Etal on intracranial aneurysm in MDCT for intracranial aneurysm, showed sensitivity and specificity of about 90%. And it also shows identifying multiple small aneurysm in patients with non-traumatic SAH, few cases. In this case of Moyamaya disease, where you can see bilateral isanoling, and there are multiple thalamorperforating and pile collaterals. In this patient with, presented with the SAH, there is aneurysm arising from the right internal carotid artery. And in this another patient, there is another aneurysm, sacular aneurysm arising from the internal carotid artery. And this patient, also we can see a small tiny aneurysm arising from the right posterior inferior artery. This is a 10-year-old girl, presented with a weakness. As you can see, there is a thickening and mirroring of left common carotid artery. In this case of AVM, in a 40-year-old female, as you can see the surface shaded display showing an AV malformation with a large internal aneurysm. And this male, 45-year-old male, there is a right paratoxapital AVM, but predominantly presenting as SAH. These are my references. Thank you.
