②微泡超声造影 定义:微泡是一种被磷脂外壳包围的惰性气体,它比红细胞小,通过肾血管,与超声波相互作用时增强肾脏的图像。微泡通过静脉注射,随着造影剂进入动脉循环,等造影剂到达肾血管时,肾就会清晰成像 应用:常用于探查肾脏肿块和性质 优势 气泡可以呼出,安全性好,没有禁忌症 适用于有对比剂使用禁忌的肾功能不全...
To better understand the pathology of renal artery stenosis, we used pre-intervention intravascular ultrasound (IVUS) to study 58 atherosclerotic renal artery lesions (49 ostial, 9 nonostial) in 36 pts undergoing stent implantation for renovascular hypertension. Measurements included reference and lesion...
Renal artery stenosisis a narrowing of the artery that carries blood to the kidney. It may occur in one or both arteries and its branches. When the artery is fully blocked then it is known asrenal artery occlusion. As the artery narrows it reduces the blood flow to the kidney and this ...
Upon reaching the renal hilum, the main renal arteries divide into anterior and posterior segmental arteries. These further divide to feed the multiple segments of the kidney. The segmental arteries, in turn, give rise to the interlobar arteries which course alongside the renal pyramids toward the...
With renal artery stenosis, ‘stenosis’ means narrowing, which refers to a progressive narrowing of the renal artery, which carries blood to the kidney.This means that the blood downstream of the narrowed spot that goes to the kidney is at lower pressure, which gets sensed by the kidney.Sinc...
Renal artery stenosis is one potentially reversible cause of high blood pressure. The diagnosis may be suspected in patients who have hypertension that is difficult to control. Diagnosis is made by imaging the artery with ultrasound, computerized tomography, or arteriography. ...
Overall filter function is influenced by inflow to the filter (renal artery stenosis and renal ischemia), integrity of the filter (nephropathy), outflow from the filter (renal vein obstruction), and disorders of collection (obstructive uropathy).
