the whole plant of biophytum petersianum was extracted with a mixture of water – alcohol (1:1) to evaluate its relaxant effect on aorta rings. in isolated wistar rat tissue, the hydro-ethanolic extract (0.1; 0.25 and 0.5 mg/ml) non-competitively antagonized calcium chloride and high-k + - induced aorta contractions in a concentration-dependent manner. moreover, the inhibition of noradrenaline–i...

Turbulent blood flow is implicated in the pathogenesis of several aortic diseases but the extent and degree of turbulent blood flow in the normal aorta is unknown. We aimed to quantify the extent and degree of turbulece in the normal aorta and to assess whether age impacts the degree of turbulence. 22 young normal males (23.7 ± 3.0 y.o.) and 20 old normal males (70.9 ± 3.5 y.o.) were examined u...

PURPOSE To clarify the postmortem multi-detector computed tomography (MDCT) vascular signs that occur shortly after death. MATERIALS AND METHODS The vascular signs in MDCT images were evaluated quantitatively in 96 early postmortem cardiac arrest patients, 47 cardiac arrest patients who survived due to resuscitation and 47 control patients without cardiac arrest. RESULTS Elliptical (40 case...

The current technology used in imaging has an increasing role medical education. concept of using image analysis programme to help estimating the age aorta, largest artery, can be clearly seen use, especially establishing changes for identification individuals. purposes study were investigate gross morphology, morphometric parameters, and correlation between parameters with aorta human cadavers...

Non-isthmic coarctation of the aorta is a rare congenital malformation in adults. Arterial hypertension frequent circumstance discovery. We reported case 22-year-old Guinean man who had been followed for 5 years hypertension. Clinically, he presented with upper limbs systolic pressure gradient 100 mmHg. The diagnosis was confirmed by thoracic angioscan, which showed 65.8% abdominal aorta. He on...

BACKGROUND External wrapping is a surgical method performed to prevent the dilatation of the aorta and to decrease the risk of its dissection and rupture. However, it is also believed to cause degeneration of the aortic wall. A biomechanical analysis was thus performed to assess the stress of the aortic wall subjected to external wrapping. METHODS A stress analysis using the finite elements m...

AIMS To better characterize patients with Marfan syndrome who have survived an acute aortic dissection and to estimate the risks of events in the descending aorta. Up until now, this portion of the aorta has not been well studied but is gaining importance due to improved patient survival. METHODS AND RESULTS We report a retrospective cohort of 100 Marfan patients who survived an aortic dissec...

This study defines normal growth for the various aortic segments in 128 spontaneously aborted human foetuses aged 15-34 weeks. With the use of anatomical dissection, digital-image analysis (using the Leica Q Win Pro 16 system) and statistical analysis (ANOVA, regression equation), a range of length measurements for the ascending aorta, aortic arch and thoracic aorta was examined. No significant...

Complex pathology of the aorta, especially in patients presenting an aneurysm involving the entire aortic arch and proximal descending aorta has been approached in one or two stages. Surgical management of those with an extremely wide diameter of the proximal descending aorta is not yet well defined. The patient in this case was an asymptomatic 47-year-old female with systemic lupus erythematos...
