A 48-year old male patient visited our hospital with uncontrolled hypertension and pair of the left leg. CT angiography shows atherosclerotic occlusion of both renal artery orifices and the left common iliac artery. Despite of medical treatment for 2 months, the clinical condition of the patient worsened. We performed the surgical revascularization with both renal arteries and aorto-left femoral artery bypass with using an 8 mm artificial vascular graft. He lived well without hypertension with using only angiotensin receptor blocker and an anticoagulant for 10 postoperative months. Using surgical revascularization for renovascular hypertension has decreased due to the development of intervention technology and medication, but this surgery is indicated in cases of renovascular hypertension with extensive atherosclerotic lesions. We report here on a case of surgical revacularization for medically Intractable atherosclerotic renovascular hypertension together with left common iliac artery occlusion.

Neurofibromatosis type 1 (NF-1) is an autosomal dominant neurocutaneous disorder, which can affect different organs or systems of the body, including the cardiovascular system. One of the more serious aspects of the disease relates to arterial involvement. In particular, renal artery stenosis is one of the most common vascular abnormalities in patients with NF-1, and the manifestations vary, ranging from no symptoms to end-stage renal failure. Treatment usually consists of antihypertensive drugs, percutaneous transluminal angioplasty, or surgery. Other causes of hypertension should be ruled out and the patient followed up for close monitoring and proper management. We report a case of bilateral renal artery stenosis and hypertension in a patient with moyamoya disease associated with neurofibromatosis type 1. This report discusses the literature available on the current subject, its clinical features, diagnosis, and treatment.

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis predominantly involving medium- or small-sized arteries, typically of the kidneys and other internal organs. Given the rarity of PAN and the variable clinical presentation, diagnosis is challenging and, to date, no definitive diagnostic marker has been identified. A patient diagnosed with immunoglobulin A nephropathy was observed to exhibit deterioration in renal function. To determine whether new structural abnormalities had developed, computed tomography scans of the kidneys, ureters, and bladder were obtained. Both kidneys exhibited multiple cortical defects, and a renal angiogram was performed to determine the cause. Angiography revealed partial obliteration of the left distal renal artery branches and multifocal extensive infarctions in both kidneys, and the patient was diagnosed with renal-limited PAN. Following steroid monotherapy, an improvement in renal function was observed. We believe that this case report may be helpful to physicians who assess and treat patients with suspected renal-limited PAN.

A 70-year old male with dilated cardiomyopathy was admitted to our hospital because of a renal stone, and a supra-renal abdominal aortic aneurysm was detected during work-up. We performed a hybrid surgery using an endovascular stent because of his co-morbidities. The operation consisted of removal of the renal stone, de-branching of the visceral artery and both renal arteries from the abdominal aorta, reperfusion of the de-branched arteries with retrograde bypass surgery using two Y-graft from the left external iliac artery, and deployment of stent graft in the abdominal aorta. Therefore, we report a case of hybrid surgery for supra-renal abdominal aortic aneurysm.

Purpose : Pulse wave velocity (PWV) and ankle brachial index (ABI) are simple, non-invasive methods to assess arterial stiffness. These parameters are also known to be closely related to cardiovascular risk factors and diseases. The purposes of this study were to measure blood pressure, PWV, ABI in healthy Korean adolescents, set up their normal values and assess their correlations. Methods : Three hundred ninety two healthy adolescents (213 boys and 179 girls) underwent measurement of brachial ankle pulse wave velocity (baPWV), ABI, body mass index(BMI) and blood pressure from four extremities. Linear regression analysis was performed to reveal the correlations between PWV, ABI and independent variables. Results : Blood pressure and PWV were significantly higher in all extremities in males compared to females. Blood pressure of both brachial and ankle showed positive correlation with body weight, height, and BMI, whereas ABI showed no correlation with any of these indices. Conclusion : Blood pressure increases as body weight, height and BMI increases. PWV shows positive correlation with blood pressure. It will be helpful to predict the risks of cardiovascular diseases in adolescents.

Renal artery pseudoaneurysm after blunt renal trauma is an uncommon complication of delayed hemorrhage, and diagnostic difficulties are experienced due to its rarity. Delayed hemorrhage after renal trauma is a life-threatening complication. Angiography is considered the gold standard to diagnose a traumatic renal artery pseudoaneurysm. We report here a case of delayed bleeding from a renal artery pseudoaneurysm that was diagnosed at 17 days after the injury and that was managed successfully with selective renal artery embolization without medical complication.

A 15 kg 6-year-old intact male Jindo dog with a history of a respiratory distress, hindlimb paralysis with necrosed skin of dorsal digit for three weeks was referred to Animal Medical Center, Chonbuk National University. Heartworm infection was identified by kit examination. In plain thoracic radiographs, dilated pulmonary arteries reverse D sign and focal interstitial pattern was compatible with heartworm infection and possible pulmonary thromboembolism. Abdominal radiographs showed poor serosal detail indicating fluid accumulation within peritoneal cavity. No evidence of musculoskeletal abnormalities was found. Ultrasonography presented focal wedge-shaped hyperechogenecity on the both poles of left kidney, weak or absent pulse on the distal to the external iliac artery as well as ascites and irregular liver margin. Multi-organ failure was strongly supposed by blood profile including leukocytosis, anemia, hemoglobinuria bililubinemia, hypoalbuminemia, imbalance of electrolytes, and increased hepatic and renal function values. Interestingly, the glucose level is remarkably lower in pelvic limb compared to thoracic limb. Suspected pulmonary thromboembolism, renal infarction and femoral arterial embolization causing hindlimb paralysis and dermatic necrosis were confirmed by 3D reconstructed CT imaging. Prior to taking a consideration of euthanasia, interventional radiology was experimentally attempted but failed due to not recovered from general anesthesia. Early and accurate diagnosis of thromboembolism is valuable and 3D reconstructed CT images might be very useful to show the correct way to treat effectively.

고혈압은 기본적으로 혈관병이다. 이 때문에 혈관이 있는 곳이면 어디든지 고혈압의 영향을 받을 수 있다. 집중 타격을 받는 곳이 심장에 영향을 공급하는 관상동맥, 뇌동맥, 신장으로 혈관과 관계된 눈도 예외가 아니다.

당뇨병을 장기간 앓게 되면 혈관이 분포한 모드 조직 또는 기관을 침범하는 임상 증후군이 발생하는데 이를 당뇨병의 만성 합병증이라고 부른다. 당뇨병 만성 합병증의 기본적인 병리생리는 혈관 질환이며 침범하는 장기와 혈관의 크기에 따라 다음과 같이 분류된다. 눈에 생기는 망막증, 신장에 생기는 신장병증, 신경 특히 말초신경에 발생하는 신경병증들은 미세혈관의 손상에 따라 발생하므로 미세혈관 합병증이라고 부르며 심장에 생기는 협심증, 뇌혈관 경색으로 대표되는 뇌졸중, 하지 동맥폐색증은 대혈관 합병증이라고 부른다.

보통 $7\sim8$월에 수확하는 수박은 수분이 96%로 대부분이 당질이며 비타민은 극히 적으나 많은 양의 과당은 신장병에 좋다고 한다. 주과육 중에 있는 citrulline과 arginine은 이뇨효과는 껍질 쪽이 뛰어나다. 또한 씨에는 linoleic acid가 풍부하여 동맥경화 예방 효과가 있다. 저장은 보통 최적 온도 $2.2\sim4.4^{\circ}C$, 최적 습도 $80\sim85%$의 저온이며 $1\sim2$주간 저장 할 수 있다.
