Prompt recognition of acute or delayed vascular insults during anterior spinal reconstructive surgery of the lower lumbar levels is paramount for successful intervention and prevention of sequelae. Although surgical exposure of the lower lumbar levels requires mindful dissection and cautious retraction of abdominal vessels, ischemic insult due to partial or ...

Anatomical variations in the cardiac veins have the potential to cause iatrogenic injuries during cardiac surgical procedures or cardiac resynchronization therapy. We present a case of an 86-year-old man, which presented with a great cardiac vein aneurysm. The great cardiac vein arose near the apex of the interventricular sulcus to ...

The treatment of hypoplastic left heart syndrome (HLHS) is clearly evolving. Over the last few years, the standard surgical approach has been modified by the application of the right ventricle to pulmonary artery conduit and regional perfusion techniques. Even more radical conceptual changes are now occurring. New treatment paradigms, such ...

Development of the aorta and pulmonary artery is a complex process involving multiple molecular genetic pathways that modulate morphogenesis of the outflow tracts and the anastomosis of branch vessels. Recent genetic studies of the cardiovascular system demonstrate that congenital and adult onset progressive disorders of the great vessels such as ...

BACKGROUND: Despite their unfavorable locations, lesions of the third ventricle can be successfully removed via an interhemispheric, transcallosal approach. In cases with normal ventricular anatomy, this approach requires unilateral or bilateral identification of the foramen of Monro. TECHNIQUE: However, in the presence of abnormal ventricular configuration such as cavum septum ...

OBJECT: The authors studied the microsurgical anatomy and endoscopic features of the pineal region and third ventricle to describe a combined microsurgical-endoscopic infratentorial-supracerebellar approach to the posterior third ventricle. Such an approach exposes the pineal gland and its complex neurovascular structures so that the third ventricle can be reached through ...

The purpose of this study was to determine whether continuing experience in prenatal diagnosis of conotruncal malformations (CTMs) has resulted in improved diagnostic accuracy and outcome. Previous reports have demonstrated particular difficulty with ascertainment of the spatial relationship of the great arteries in patients with CTM. The prognosis for fetuses ...

Transposition of great arteries is the consequence of abnormal aorticopulmonary septation. Animal embryonic data indicate that septation and elastogenesis are related events, but human and clinical data are not available. We tested the hypothesis that large artery elastic function was impaired in patients with transposition of great arteries. We studied ...

Transthoracic echocardiography allows noninvasive assessment of the structure and function of the great vessels of the heart. We report a case of a 70-year-old man who had an isolated, mildly obstructive, supravalvular pulmonary artery ridge that was detected incidentally with transthoracic echocardiography. This report confirms the utility of transthoracic echocardiography ...

In dynamic susceptibility contrast MRI, the shape of the arterial input function (AIF) is commonly obtained in the near vicinity of the middle cerebral artery (MCA). However, the tissue regions where the AIF is sampled also have significant perfusion, which contributes to T(2)* changes. We investigate whether correction of this ...

Congenital heart defects frequently involve a failure of outflow tract (OFT) formation during development. We analyzed the remodeling of the OFT, using the y96-Myf5-nlacZ-16 transgene, which marks a subpopulation of myocardial cells of the pulmonary trunk. Expression analyses of reporter transcript and protein suggest that the myocardial wall of the ...

Right ventricular (RV) dysfunction may occur in patients after the atrial switch operation for d-transposition of the great arteries (d-TGA) and can be an important complication. Noninvasive assessment of RV function using echocardiography is necessary for following up these patients. We evaluated RV function using the Doppler Tei index (RV ...

Pulmonary stenosis (PS) can be seen from the right ventricular outflow tract to the peripheral pulmonary arteries. Most frequently, the obstruction occurs at the level of the pulmonary valve; however, it occurs less frequently at the infindibular level within the trabecular component of the right ventricle or within the pulmonary ...
