Renal hypertension is found to be the cause in 5-15ft of patients with hypertension, and may be vascular or parenchymal in nature. Renal studies in diagnostic technique and vascular reconstructive techniques now enable successful management in many patients with renal hypertension. We experienced one case of renovascular hypertension due to renal vein hypoplasia. This rare renal venous hypertension has been diagnosed preoperatively and can be cured by nephrectomy, so we reported this case with brief review of the literature.

Renal artery embolism is an uncommon event, but a correct diagnosis and appropriate treatment are often delayed. We report a case in which viability was sustained by surgical intervention 18 hours after an episode of embolism that produced hypertension.

Atherosclerotic renovascular hypertension is a form of secondary hypertension due to renal artery stenosis. After the introduction of medical therapy such as with statins and angiotensin blocking agents, it has been considered a very slowly progressive disease. In the 1990s, surgical methods were compared to radiological intervention and showed no additional benefits. Recent clinical data also demonstrate that in cases of relatively stable atherosclerotic renovascular disease, medical therapy is as effective as other interventions with regard to patient outcomes. In this paper the recent clinical outcomes are reviewed.

Renal artery stenosis is a major cause of renovascular hypertension and the most common cause of treatable secondary hypertension. There are several methods to treat renal artery stenosis, including surgery, percutaneous transluminal renal angioplasty(PTRA), and renal artery stenting(RAS). But, renal artery embolization can be tried in atherosclerotic stenosis, multiple stenosis, microaneurysm, and stenosis difficult to try PTRA or RAS. We report a case of renovascular hypertension in a 14-year-old female who had multiple segmental renal artery stenosis. Hypertension was controlled by renal ablation therapy with renal artery embolization.

Renal artery stenosis is a cause of secondary hypertension which can be cured by surgical or radiological intervention such as percutaneous transluminal renal artery stent placement. In this case we present a subcapsular hematoma of the kidney, a complication following percutaneous transluminal stent placement in the renal artery. Reperfusion injury to the kidney may be a possible mechanism of subcapsular hematoma of the kidney. Long standing severe renal artery stenosis and high pre- and post- procedure pressure gradient might contribute to the complication.

Renovascular hypertension is the leading cause of surgically curable arterial hypertension. With the marked advancement in the technique of vascular surgery, renal revascularization is preferred to nephrectomy. It is used for the recovery of impaired function or the prevention of renal failure and the control of hypertension. We report a case of renovascular hypertension with the nonfunction of the left kidney due to complete renal artery obstruction, treated successfully with an aortorenal bypass graft.

Renovascular hypertension caused by renal artery stenosis is an uncommon but curative cause of hypertension in children. We report a case of recurrent severe hypertension caused by renovascular hypertension. After recurrence of hypertension after redo percutaneous transluminal renal angioplasty, the blood pressure was finally controlled by renal autotransplantation. This case demonstrates the importance of considering renovascular hypertension as a cause of severe hypertension in children. Also, renal autotransplantation should be considered as a viable treatment option for treatment of renovascular hypertension that is recurrent after renal angioplasty.

In hypertensive patients it is very important to detect renal artery stenosis or pheochromocytoma, since both diseases are curable causes of hypertension. However, renal artery stenosis can be induced by pheochromocytoma, when the diagnosis of the two simultaneous disease is very difficult. We experienced two cases of pheochromocytoma presented as renal artery stenosis. Pheochromcytoma was overlooked when renovascular hypertension was diagnosed. Pheochromocytoma was found during surgery in one patient and after angioplasty in the other. In both cases, BP returned to normal after surgical removal of pheochromocytoma without repair of the stenosis. Prevention of ineffective and unnecessary renal artery angioplasty of surgery requires knowledge of this unusal association between pheochromocytoma and renal artery stenosis and a high degree of clinical alertness for pheochromocytoma.

Renal hypertension is found to be the cause in 5-15% of patients with hypertension, and may be vascular or renal parenchymal in nature. Recent advances in diagnostic technique and vascular reconstructive techniques now enable successful management in many patients with renal hypertension. We observed one case of renovascular hypertension due to right renal hypoplasia and left renal arterial stenosis, in 22 year-old female patient with complaints of headache and dizziness for 10 days. The treatment was done by right nephrectomy and left aortorenal bypass procedure with saphenous vin. Herein we reported a case of renovascular hypertension with a review of the literatures.
