right aortic arch with vascular ring and aberrant left subclavian Artery prenatal diagnosis assisted by three dimensional power doppler ultrasound
Ultrasound in Obstetrics & Gynecology, 2003Co-Authors: R Chaoui, M Schneider, K KalacheAbstract:The prenatal detection of a right-sided aortic arch achieved mainly by targeted visualization of the threevessel and three vessels and trachea (3VT) view, with or without color Doppler, has been discussed recently in this journal1–4. Two typical forms of a right aortic arch can be distinguished5,6. In one condition a vascular ring is found around the trachea, the so-called U-sign prenatally (Figure 1)2,3. The trachea and esophagus are entrapped between the right aortic arch and the left ductus arteriosus and this abnormality is often an isolated incidental finding prenatally2. In the other condition, both the aorta and ductus arteriosus lie to the right of the trachea without a vascular ring. This condition is very commonly associated with cardiac anomalies5. The branching pattern of the great vessels arising from the aortic arch in both conditions is of major interest in pediatric cardiology5,6. The right aortic arch without a vascular ring usually exhibits mirror image branching of the arteries with the left innominate (brachiocephalic) Artery arising first followed by the right common carotid and right subclavian Artery6. By contrast, the right aortic arch with vascular ring very often has an association with an aberrant left subclavian Artery. The left common carotid arises first from the aortic arch, followed by the right common carotid, right subclavian Artery, and finally a retroesophageal vessel segment from which the left subclavian Artery arises and the ductus arteriosus connects. The retroesophageal (and retrotracheal) vessel segment is known as the diverticulum of Kommerell. In other words, the left subclavian Artery is connected ventrally to the ductus arteriosus arising from the left pulmonary Artery, and dorsally through the Kommerell’s diverticulum to the descending aorta. In postnatal life, after closure of the ductus arteriosus, blood enters the left subclavian Artery via the descending aorta and Kommerell’s diverticulum4. Prenatal assessment of a right-sided aortic arch and its branching pattern requires scanning in such planes as a transverse 3VT view (Figure 1), oblique cephalad Left

vaskularisasi pembuluh darah arteri mata organum visus pada kambing lokal capra sp
Jurnal Agripet, 2013Co-Authors: Idawati Nasution, Ezy Yulanda Rezki, Hamny HamnyAbstract:Eye ( organum visus ) vascular of local goat ( capra sp .) ABSTRACT . The aim of the study was to determine of eye vascular in local goat ( Capra sp .) The study used a local goat, aged 2 years old. Observation was made after specimen preparation. The observations was documented using a digital camera and analyzed descriptively. The vascular to the eye originated from externa ophthalmica Artery and divides into several branched musculares arteries, lacrimalis Artery, rete mirabile ophthalmicum gives off supraorbitalis Artery, ethmoidalis Artery, anteriores ciliares arteries and anastomoses with interna ophthalmica Artery and devides into lateralis posterior longae ciliares arteries and medialis posterior longae ciliares arteries and the terminal branched into lateralis posterior shortae ciliares arteries and medialis posterior shortae ciliares arteries. Superficial temporalis Artery gives off two branches lateralis inferior palpebral Artery and lateralis superior palpebral Artery. Malaris Artery gives off two branched medial inferior palpebral Artery and medial superior palpebral Artery.

Successful Treatment of Recurrent Basilar Artery Occlusion with Intra-Arterial Thrombolysis and Vertebral Artery Coiling in a Child
Neurocritical Care, 2012Co-Authors: John Condie, Ali Shaibani, Mark S. WainwrightAbstract:Background Signs of brainstem ischemia in children may be subtle, and outcome following basilar Artery occlusion is often poor. There currently are no guidelines in children regarding the best methods to diagnose and treat basilar Artery occlusion. Methods Case report and literature review. Results We describe the presentation and management of recurrent basilar Artery occlusion in a previously healthy 5-year-old boy with vertebral Artery dissection. Treatment included emergent intra-arterial tPA and mechanical thrombolysis of basilar Artery clot, followed by later coiling of the vertebral Artery to prevent recurring episodes of basilar Artery ischemia. Conclusion Management of brainstem stroke in children requires coordination of neurology, critical care, and interventional radiology services. Delayed intra-arterial thrombolysis and vertebral Artery coiling can be successfully used to treat basilar Artery occlusion and prevent the recurrence of brainstem ischemia in children .

Congenital Right Subclavian Artery Aneurysm : a Case Report
Acta Chirurgica Belgica, 2004Co-Authors: Frederic Mergan, D. Naitmazi, Jean-pierre DereumeAbstract:Aneurysms of the subclavian Artery are unusual. The most common causes are atherosclerosis and trauma. We report one case of an elongated and tortuous right subclavian Artery with an aneurysm involving the origin of the right vertebral Artery. The patient underwent resection of the lesion with an end-to-end anastomosis of the subclavian Artery and implantation of the right vertebral Artery into the right common carotid Artery. Results were consistent with a rare congenital subclavian aneurysm.
