Renovascular hypertension is caused by narrowing of the arteries supplying the kidneys. There are several methods to treat renal artery stenosis, such as medications, percutaneous transluminal renal angioplasty, and atherosclerosis. A boy presented to our hospital with severe hypertension. Computed tomography angiogram revealed severe narrowing of the left renal artery and hypoplastic left kidn...

• Renal artery compression due to a diaphragmatic crus is rare cause of secondary hypertension. This usually combination high origin the renal and prominent leading its similar as median arcuate syndrome. We report case 31-year-old male with uncontrolled hypertension despite four antihypertensive medications. A surgical decompression associated direct reimplantation left was performed. The outc...

BACKGROUND Malignant hypertension is a condition characterized by severe hypertension and multi-organ ischemic complications. Albeit mortality and renal survival have improved with antihypertensive therapy, progression to end-stage renal disease remains a significant cause of morbidity and mortality. The underlying cause of malignant hypertension, which can be primary or secondary hypertension,...

BACKGROUND Midaortic syndrome (MAS) is a rare vascular anomaly characterized by segmental narrowing of the distal descending thoracic or abdominal aorta. Renal or visceral arteries may also be affected to varying degrees. MAS is often associated with renovascular hypertension, and requires early intervention. When medical therapy and percutaneous interventions fail to control hypertension, surg...

The authors report and discuss a case of bilateral renal artery stenosis in a hypertensive 9 year-old girl that was first suspected with Technetium-dimercaptosuccinic acid renal scintigraphy. The scintigraphy showed signs of acute renal failure while the patient was on enalapril for controlling her hypertension. Bilateral renal artery stenosis was confirmed with computed tomography angiography....

The authors report and discuss a case of bilateral renal artery stenosis in a hypertensive 9 year-old girl that was first suspected with (99m)Technetium-dimercaptosuccinic acid renal scintigraphy. The scintigraphy showed signs of acute renal failure while the patient was on enalapril for controlling her hypertension. Bilateral renal artery stenosis was confirmed with computed tomography angiogr...

Neurofibromatosis (NF1) is a relatively common autosomal dominant disorder. Secondary causes of hypertension, such as renovascular disease, coarctation of the abdominal aorta or phaeochromocytoma, may be identified in up to 1% of patients with NF1. Usually, renal angiography, which is always used to confirm the diagnosis of renovascular hypertension, reveals stenoses and rarely bilateral or uni...

A 76-year-old man developed progressive renal dysfunction with refractory hypertension. Bilateral renal artery stenosis due to atherosclerosis was revealed. Both the hypertension and renal dysfunction were improved by percutaneous transluminal renal angioplasty with stenting. Based on the rapidly progressive elevation of plasma renin activity and the improvement of both renal dysfunction and hy...

A 21-year-old female with a history of right nephrectomy due to trauma presented several years multi-drug resistant hypertension. Her workup included negative autoimmune and vasculitidies panels urine catecholamines. Computed tomography imaging showed an acute hairpin turn her left renal artery. Intra-operatively, the artery demonstrated kinking exhalation. She underwent excision diseased porti...

hypertension in newborn infants, particularly those requiring intensive care, is becoming increasingly recognized, with prevalence of 0.2-3%. recent studies have established normative tables for blood pressure (bp) in both term and pre-term infants based on the gestational age, postnatal age, gender, weight and height, identifying the neonates at increased risk for early-onset cardiovascular di...
