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.

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.

Role of renal angiography in the diagnosis of renal disease is changing after the advent of new imaging techniques such as ultrasonography and CT. Ultrasonography and CT examination started to be used clinically on March 1, 1979, in Seoul National University Hospital. Total 315 cases of renal angiography were made for recent 7 years from September 1, 1975 to August 30, 1982, 117 cases in 3 1/2 years before and 198 cases in 31/2 years after the installation of new imaging modalities. To evaluate the changing role of renal angiography, sequential flow patterns of various radiological examination were classified into 7 categories. Results of the analysis were as follows; 1. The increased ratio of renal angiography after the advent of new imaging modalities is 1.7 and slightly less than that of total radiological examinations. 2. The role of renal angiography is decreased in the diagnostic work-up of renal mass, hematuria, adrenal disease, renal failure and other renal evaluation. Angiography has significant role still in the evaluation for renovascular hypertension, renal trauma, transplantation donor, renalvein thrombosis and artificial embolization. 3. The most frequent flow pattern is AII (IVP-Aug) before and BII (IVP-US [CT]-Aug) after the advent of new imaging modalities.

The application of fine needle aspiration (FNA) cytology to the soft tissue tumors had been neglected. In recent years, however, FNA has been used increasingly in the preoperative diagnosis of these tumors due to its usefulness and accuracy. We present 3 cases of liposarcoma, myxoid, myxoid with round cell, and pleomorphic, diagnosed by FNA cytology with histologic confirmation. Good correlation between his- tologic and FNA cytologic findings was found. Although the cytologic appearances of liposarcomas varied with histologic type, the main criterion was the presence of atypical multivacuolated lipoblast with characteristically scalloped nuclei.

Renal angiogram offers valuable information in evaluating the patients with renal tumor, renal tuberculosis, polycystic kidney, hematuria, and renovascular hypertension. The author observed themorphological findings of renal disease, such as renal tumor, renal tbc, and polycystic kidney by selective renal angiography. A clinical evaluation were performed 36 patients of selective renal angiography which were done from 1972 to 1975. The result were as follows: Of 36 patients, comparison in clinical diagnosis with selective renal angiographic diagnosis. 1) Cases of correct clinical diagnosis with I.V.P. were 21 cases. 2) Cases of incorrect clinical diagnosis with I.V.P. were 3 cases. 3) At all, 12 cases were confirmed by renal angiography.

Primary reninism is a rare cause of hypertension manifesting along with hypokalemia. A high level of plasma renin activity and a high level of serum aldosterone are the whole markers of primary reninism. Upon making the diagnosis of primary reninism, other more common causes of aldosteronism must be differentiated, such as renovascular hypertension and primary aldosteronism. Primary reninism is commonly caused by juxtaglomerular cell tumor, which is one of the curable causes of hypertension, and this can be successfully treated by conservative surgery. We report here on a case of primary reninism that was caused by juxtaglomerular cell tumor that developed in a 22-year-old female patient. She was recently diagnosed with hypertension and hypokalemia. She had markedly elevated plasma renin activity and an increased serum aldosterone concentration. Computed tomography revealed a mass located in the right kidney and selective renal vein sampling suggested that the mass was secreting an excess of renin. Right nephrectomy was done and her hypertension with hypokalemia was successfully treated. We report here a case of primary reninism that presented with juxtaglomerular cell tumor along with a review of the literature

Renal angiography has applications in the diagnosis of renal tumor and renovascular hypertension, and provides important anatomical information that can influence the surgical management. Recently the approach to the vascular system for diagnosis by means of Seldinger technique hag been expended to include a variety of therapeutic manner. So, embolization of renal carcinoma is being used with increasing frequency. Radiologic findings associated with presenting symptoms and signs were analysed in 51 cases of renal angiography, during the period of October 1978 to October 1982. The following results were obtained. 1. Male to female ratio was approximately 1:1 and peak incidence was in the sixth decade. 2. The main symptoms and signs of patients were hematuria, flank pain, hypertension and palpable mass, in order of frequency. 3. In 7 hypertensive patients with delayed visualization on the excretory urogram. angiography shows 2 cases of renal artery stenosis, one case of Takayasu's disease and absence of abnormal vasculature in 4 cases. 4. It is suggested most valuable technique for correct diagnosis of renal vascular disease. some of other congenital anomalies, and renal vascular mapping for renal surgery.

Renovascular hypertension secondary to renal artery vascular disease is the most common form of surgically correctable hypertension. The common causes of renovascular hypertension are atherosclerosis, fibromuscular dysplasia, and Takayasu arteritis. Takayasu arteritis is a chronic nonspecific arteritis of unkown cause that is relatively prevalant in young female subjects. It has been well known that the pathologic feature of the disease consist predominantly of occulsive changes in the aorta and the origin of its major branches. The most important pathogenetic mechanism of hypertension seems to be through renal artery stenosis. We have experimented three hypertensive patients with Takayasu arteritis experienced. Basic diagnosis was established by angiographic study. This article presents surgical treatment methods of Takayasu arteritis with renovascular hypertension and brief review of literatures.

Renal artery aneurysms, previously considered to be rare, have been diagnosed more frequently in recent years mainly due to extensive use of angiography. Most aneurysms are asymptomatic, found incidentally, and their presenting symptoms may include microscopic or gross hematuria, flank pain and renovascular hypertension. The diagnosis may be highly suggestive when rim like calcification is exist on KUB with symptoms, and renal angiography is needed to confirm diagnosis. The treatment may be conservative or operative according to size and site. Operative management may include nephrectomy, revascularization, and aneurysmectomy. We report a case of left renal artery aneurysm with incomplete ring-like calcification in a 52-year-old hypertensive woman. The selective renal angiography showed renal artery aneurysm arising from the bifurcation of left main renal artery Because of the risk of aneurysmal rupture through its weak portion with incomplete calcification and the possibility of the renovascular hypertension due to anastomotic stenosis after aneurysmectomy, we performed nephrectomy.
