  • 신성 고혈압은 소아기 이차성 고혈압의 흔한 원인이며, 그 중 신동맥 협착은 치료 가능한 고혈압의 가장 흔한 원인이다. 신혈관성 고혈압 치료로 약물치료에 반응하지 않는 경우 혹은 초기 단계부터 치료목적으로 경피적 혈관 성형술과 신장동맥 스텐트 등의 중재적 혈관 성형술이나 수술요법이 시행할 수 있다. 죽상 경화형 협착, 다발성의 협착, 미세동맥류, 그리고 협착 부위가 혈관 성형술이나 stent로 교정되기 어려운 경우에는 부분적 혹은 완전 신장동맥 색전술이 시도될 수 있다. 저자들은 신장동맥 색전술을 이용한 renal ablation요법으로 고혈압의 호전을 보인 신혈관 고혈압증 1례를 경험하였기에 보고하는 바이다.

  • In stenosis of a segmental branch or among multiple renal arteries, Doppler sampling of intrarenal arteries in the upper, mid and lower poles demonstrates strikingly different waveform patterns that might otherwise be overlooked. We report a case of segmental branch renal artery stenosis in which a pulsus parvus et tardus waveform was observed in a segmental branch of a renal artery. In this case, systematic analysis of Doppler waveforms of intrarenal arteries at more than three different locations facilitated a rapid and confident diagnosis of segmental branch renal artery stenosis.

  • Here, we present the case of a 2-month-old male infant with hyponatremic hypertensive syndrome resulting from stenosis of the right proximal and mid-renal arteries. The patient exhibited nephrotic-range proteinuria, low serum albumin, increased serum creatinine, and elevated renin and aldosterone levels. Doppler ultrasonography and computed tomography angiography revealed decreased vascular flow in the small right renal artery. Following a successful percutaneous balloon angioplasty, the patient experienced a decrease in blood pressure and normalization of serum electrolyte levels within a few days. However, it took 3 months for the proteinuria to resolve completely. This case is significant as it represents the first reported instance of a neonate presenting with clinical features resembling congenital nephrotic syndrome caused by renal artery stenosis that was successfully treated with percutaneous renal angioplasty.

  • Takayasu씨 동맥염은 원인이 잘 모르는 만성 염증성 질환의 일종이다. 이 질병은 주로 대동맥궁과 대동맥의 주분지를 잘 침범하는 것으로 알려져 있으며, 관상동맥과 신동맥을 동시에 침범하는 경우는 극히 드물다. 최근 고려대학교 흉부외과학교실에서는 관상동맥과 신동맥을 동시 에 침범한 Takayasu씨 동맥 염 환자를 성공적으로 치료하였기에 보고하는 바이다. 환자는 23세 여자로, 운동시의 흉통을 주소로 내원하였다. 혈관조영술상 좌주관상동맥, 양측의 신동맥, 좌쇄골하동맥의 협착 소견을 보였다. 치료로는 양측의 신동맥에 스텐트를 삽입하는 혈관성형술을 시행하였고, 1주일 뒤 대복재정맥을 이용한 관상동맥우회술과 인조혈관(PIFE)을 이용한 대동맥-쇄골하동맥간 우회술을 동시에 시행하였다. 환자는 수술 후 13일째 특별한 합병증 없이 퇴원하였다.

  • A 63 year old male had suffered from hypertension and angina pectoris for 4 years, On physical examination, blood pressure was 150/110 mmHg with medication of antihypertensive drugs. Aortogram showed the stenosis of the left renal artery, the complete occlusion of the right renal artery, and atherosclerotic change of abdominal aorta. Blood urea nitrogen was 25 mg/dl, serum creatinine was 1.2 mg/dl, and renin activity in peripheral blood was 8.7 ng /ml /hour, The stenosis of left renal artery and the complete occlusion of right renal artery should have produced the renovascular hypertension Bilateral aorto-renal bypasses with saphenous grafts were done for treatment of ren-ovascular hypertension Postoperatively, blood pressure was normalized with only small dosage of antihypertensive drugs.

  • Takayasu’s disease produces the occlusive and aneurysmal lesions of major branches of the aorta. Angiography is the most important diagnostic procedure in Takayasu’s disease. Surgical treatment is often justified to avoid the possible lethal consequences of hypertension on the heart, kidney, and brain, as well as in the case of aneurysm because of its risk of rupture. We experienced one case of the Takayasu’s disease associated with abdominal coarctation and renovascular hypertension. The patient was 17 years old female and had suffered from hypertension for 14 months. On physical examination, BP was 150/100 mmHg in the right arm and 120/80 mmHg in the left arm. The pulses of the left brachial and femoral arteries were weakly palpable. Aortogram showed the stenosis of the left common and subclavian arteries, coarctation of the abdominal aorta, and stenosis of the right renal artery and complete occlusion of the left renal artery. The stenosis of the right renal artery and the occlusion of the left renal artery produced the renovascular hypertension. She underwent aorta-aortic bypass for the coarctation of the abdominal aorta and aorta-renal bypass for treatment of renovascular hypertension Postoperatively, both femoral pulses were equally palpable. On discharge, antihypertensive drugs were discontinued. She has remained normotensive for last one year.

  • 신경섬유종은 드문 전신 질환으로 여러 장기를 침범하며 특히 다양한 크기의 혈관을 침범하여 혈관병을 발생시켜 대동맥 협착, 모야모야병, 신동맥 협착 등을 일으킨다. 이로 인하여 약 0.4-6.4%의 환자에서 고혈압 증상이 있으며 이의 원인으로 신혈관 협착이 가장 흔하다. 특히 약물에도 조절되지 않는 고혈압은 혈관 협착 등이 원인이 될 수 있기 때문에 도플러 초음파 검사나 전산화 혈관 조영술 등의 정밀 검사가 필요하다. 이에 대한 치료는 약물 치료, 피부경유 혈관경유혈관성형술, 수술적 치료 등의 병합 요법으로 이루어지며 재협착 발생률이 높기 때문에 주의 깊은 추적 관찰이 필요하다. 본 저자들은 제 1형 신경섬유종증에 합병된 모야모야병에서 신장동맥 협착을 동반한 고혈압을 진단받고 치료한 1례를 경험하였기에 보고하는 바이다.

신동맥분지협착에 의한 신혈관성고혈압 예에서 캅토프릴투여후 $^{99m}Tc-DMSA$ 신 스캔 (Captopril Enhanced $^{99m}Tc-DMSA$ Renal Scintigraphy in A Case of Renovascular Hypertension Due to Branch Renal Artery Stenosis)

  • Radionuclide renal scintigraphies were performed in a 24-year-old man with right renal artery branch stenosis. Captopril enhanced $^{99m}Tc-DTPA$ renal scintigraphy revealed no abnormal finding in the right kidney. But, $^{99m}Tc-DMSA$ renal scintigraphy showed regional cortical photon deficient area corresponding to the area supplied by the stenotic branch artery. The defect size increased in captopril enhanced $^{99m}Tc-DMSA$ renal scintigrphy and nearly disappeared after successful transluminal renal angioplasty. This case suggests that the captopril enhanced $^{99m}Tc-DMSA$ renal scintigraphy may be a useful method in the evaluation of renovascular hypertension, especially due to branch renal srtery stenosis.

  • There have been some case reports of the coexistence of extraadrenal pheochromocytoma and renal artery stenosis. Some reporters proposed that their coexistence may be associated through a common pathophysiological mechanism mediated by catecholamine secretion. Also some noted that trasient renal artery stenosis due to a spasm was induced by the catecholamines released from pheochromacytoma. We report a case of left paraaortic extraadrenal pheochromacytoma that had a transient oral captopril test positive result. After 5 days ${\alpha}$-antagonist reduced the vasospastic response of catecholamines. After surgical removal of the tumor, plasma catecholamines and urinary vanillyhnandelic acid concentrations as well as the blood pressure level, were restored to normal.
