1/117. Tubular stenosis of the aorta with aortic fibromuscular dysplasia.The autopsy findings in a 2-year-old girl with severe hypertension resulting from stenosis of the lower part of the thoracic and the abdominal aorta were reviewed. The lower portion of the thoracic aorta and the abdominal aorta showed uniform narrowing down to the level of the bifurcation of iliac arteries. Histologically, the aortic wall of the stenotic site showed irregular proliferation of smooth muscle cells and collagen fibers. The elastic fibers had disappeared from outside the media. No intimal thickening and inflammatory cell infiltration were observed. These histologic changes of the aortic media in this case are apparently similar to fibromuscular dysplasia (medial hyperplasia).- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
2/117. Post-Mustard procedure pulmonary venous obstruction: An opportunity for anatomic correction with a one-stage arterial switch.A 14-year-old boy after a Mustard procedure for transposition of the great arteries developed pulmonary hypertension secondary to baffle obstruction. This occurred over several years without apparent significant symptomatology. Systemic-level pressure prevailed in the left (pulmonary) ventricle and provided an opportunity to perform a successful one-stage arterial switch.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
3/117. Anastomotic pulmonary hypertension after lung transplantation for primary pulmonary hypertension: report of surgical correction.This report describes a patient who developed pulmonary hypertension 6 years after lung transplantation for primary pulmonary hypertension (PPH). Evaluation with right heart catheterization followed by pulmonary angiography, however, demonstrated that the pulmonary hypertension was secondary to an anastomotic narrowing of the pulmonary artery, rather than a recurrence of her PPH. Vascular complications of lung transplantation should be considered in patients who experience exertional dyspnea after lung transplantation. The suggestion of pulmonary hypertension on echocardiography should prompt further evaluation, including meticulous hemodynamic measurements.- - - - - - - - - - ranking = 12keywords = hypertension (Clic here for more details about this article) |
4/117. Segmental portal hypertension due to splenic vein obstruction: imaging findings and diagnostic pitfalls in four cases.Segmental portal hypertension due to isolated splenic vein obstruction is a rare but important entity as it is the only curable cause of portal hypertension by splenectomy. Four cases are presented illustrating the radiological features of splenic vein obstruction, and the diagnostic pitfalls that arose in patients with complicated clinical presentations.- - - - - - - - - - ranking = 6keywords = hypertension (Clic here for more details about this article) |
5/117. Congenital pulmonary venous stenosis presenting as persistent pulmonary hypertension of the newborn.Congenital pulmonary venous stenosis (CPVS) has been previously described in older infants and children, typically manifesting as failure to thrive with congestive heart failure and subsequent respiratory deterioration. We report on 2 cases of CPVS which presented during the immediate newborn period as severe persistent pulmonary hypertension of the newborn.- - - - - - - - - - ranking = 5keywords = hypertension (Clic here for more details about this article) |
6/117. hepatopulmonary syndrome in inferior vena cava obstruction responding to cavoplasty.Reports show that hepatopulmonary syndrome mostly occurs in the setting of advanced hepatic dysfunction, with the associated vasoactive substance imbalance believed to be responsible for its pathogenesis. However, hepatopulmonary syndrome has also been reported in cases of mild hepatic dysfunction or noncirrhotic portal hypertension, indicating that portal hypertension also plays a part in the pathogenesis. liver transplantation remains the only therapeutic option of proven benefit. We describe 2 cases of hepatopulmonary syndrome in the setting of inferior vena cava (suprahepatic) obstruction, but with minimal hepatic dysfunction. After balloon cavoplasty, 1 patient showed, in addition to improvement of the features of hepatic outflow obstruction, significant reduction of dyspnea, cyanosis, and hypoxemia with arterial blood gas normalization within 2 weeks and intrapulmonary shunt reversal within 8 weeks. This implies that hemodynamic alterations (such as portal hypertension) independently contribute to the pathogenesis of hepatopulmonary syndrome in at least some of the cases. Therapies aimed at correcting these abnormal hemodynamics may be important in the treatment of this condition, especially when the hepatic functional status by itself does not warrant a liver transplant.- - - - - - - - - - ranking = 3keywords = hypertension (Clic here for more details about this article) |
7/117. pulmonary artery stenosis 5 years after single lung transplantation in primary pulmonary hypertension.This is a case report about a 56-year-old female patient with primary pulmonary hypertension who underwent single, right lung transplantation. Five years postoperatively she developed signs of right heart failure. history and physical examination suggested pulmonary artery stenosis. diagnosis was confirmed by pulmonary angiography. Percutaneous placement of a balloon expandable stent normalized pulmonary artery pressure.- - - - - - - - - - ranking = 5keywords = hypertension (Clic here for more details about this article) |
8/117. Tandem stenting of crossed renal arteries with ostial stenosis.Ostial stenosis of renal arteries has been shown to respond favorably to stenting. Heterogeneity of renal artery anatomy is very common and often increases the technical difficulty of percutaneous treatment of stenotic lesions. We present the case of a 69-year-old man with severe hypertension who had 2 right renal arteries, both of which had ostial stenosis. We treated these stenoses with simultaneous stenting of both renal ostia. Since the procedure, the patient has had significantly improved control of his hypertension.- - - - - - - - - - ranking = 2keywords = hypertension (Clic here for more details about this article) |
9/117. Left cervical aortic arch with aortic coarctation and saccular aneurysm.Cervical aortic arch is a very rare malformation and is occasionally accompanied by other cardiovascular anomalies. A 48-year-old male patient had a left cervical aortic arch with aortic coarctation and saccular aneurysm distal to the coarcted segment. The major clinical manifestations were upper body hypertension with a 50-mmHg discrepancy between the upper and lower limbs and a loud continuous murmur in the upper chest and back. magnetic resonance angiography successfully depicted the anomalous aorta, and the aortic coarctation and aneurysm were surgically resected and the thoracic aorta was reconstructed. The discrepancy in blood pressure diminished after the operation, but antihypertensive medication was continued to satisfactorily control the hypertension.- - - - - - - - - - ranking = 2keywords = hypertension (Clic here for more details about this article) |
10/117. Bilateral medial frontal infarction in a case of azygous anterior cerebral artery stenosis.We describe the unusual case of a 63-year-old woman with a history of arterial hypertension who presented a sudden weakness of the lower limbs followed by mutism, akinesia and dyspraxia. Magnetic resonance images showed a bilateral medial frontal infarction. Digital subtraction angiography documented a right azygous anterior cerebral artery with severe stenosis in its sub-callosal tract; the left anterior cerebral artery showed mild hypoplasia with only sub-frontal and fronto-polar branches. No embolic source was documented. Afterwards the patient presented a gradual and partial recovery of both motor and cognitive functions.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
