        경피적 동맥확장술을 이용한 당뇨족 허혈의 치료

        김홍렬,한승규,나승운,김현석,김우경,Kim, Hong-Ryul,Han, Seung-Kyu,Rha, Seung-Woon,Kim, Hyon-Surk,Kim, Woo-Kyung 대한성형외과학회 2010 Archives of Plastic Surgery Vol.37 No.2

        Purpose: In treating diabetic foot ulcers, satisfactory vascularity is an essential prerequisite. To improve vascularity, a bypass graft has long been carried out. Recently, however, percutaneous transluminal angioplasty (PTA) has also been tried since the PTA is less invasive than the bypass graft. However, publication demonstrating the improvement of vascularity after the PTA are lacking. Therefore, this study was designed to show usefulness of the PTA in treating vasculopathy of diabetic foot. Materials: and Methods This study included 30 feet of 24 ischemic diabetic foot patients. Inclusion criteria were diabetes (duration > 5 years) and a significant lower extremity ischemia, as determined by a transcutaneous oxygen pressure ($TcpO_2$) < 30 mmHg. The PTA was carried out in 61 arteries. PTA procedure was considered successful, when residual stenosis was less than 30%. The procedure was considered failed when residual stenosis was more than 50%. Residual stenosis between 30% and 50% was considered acceptable. For evaluation of PTA effect, foot $TcpO_2$ and infrared thermography were measured before and 7th day after PTA. Results: Immediately after PTA performed in 61 arteries, 58 and 3 arteries were evaluated as being successful and acceptable, respectively. Before PTA, average foot $TcpO_2$ was $12.6{\pm}8.8$ mmHg and its value was increased to $44.2{\pm}23.9$ on 7th day after PTA (p<0.01). Average skin temperature was $31.8{\pm}1.2^{\circ}C$ before PTA and it was increased to $33.5{\pm}1.1^{\circ}C$ on 7th day after PTA (p<0.01). Conclusion: PTA procedure increases tissue oxygenation of ischemic diabetic feet which do not have wound healing potential due to low tissue oxygenation, to the level of possible wound healing. In addition, PTA increases skin temperature of ischemic diabetic feet which can imply an improvement of peripheral circulation.

        아세틸 콜린 유발 검사시 허혈성 심전도 변화와 흉통의 발생이 내피세포 기능장애에 미치는 영향

        최철웅(Cheol Ung Choi),나승운(Seung-Woon Rha),김선원(Sun Won Kim),진오(Jin Oh Na),임홍의(Hong Euy Lim),김진원(Jin Won Kim),김응주(Eung Ju Kim),한성우(Seong Woo Han),박창규(Chang Gyu Park),서홍석(Hong Seog Seo),오동주(Dong Joo Oh) 대한임상노인의학회 2010 대한임상노인의학회지 Vol.11 No.4

        연구배경: 아세틸 콜린 유발 검사시 발생하는 흉통과 허혈성 심전도 변화가 아세틸 콜린에 의해 발생하는 관상동맥의 내피세포 기능에 어떤 영향을 주는지 알아보고자 했다. 방법: 흉통으로 내원하여 관상동맥 조영술과 아세틸 콜린 유발검사를 시행받은 1,085명의 환자를 대상으로 하였다. 아세틸 콜린 유발 검사를 하는 동안 허혈성 심전도 변화 및 흉통의 발생 유무에 따른 관상동맥 내피세포 기능의 특징을 비교하였다. 결과: 539명의 환자에서 아세틸 콜린 검사시 내피세포 기능 장애가 발생 하였다. 허혈성 심전도 변화가 있었던 그룹이 심전도 변화가 없었던 그룹보다 흉통이 더 많았고(78.1% vs. 60.8%, P=0.007), 관상동맥 조영술상 다발성 관상동맥 경련이 빈번하였고(59.4% vs. 40.6%, P=0.004), 관상동맥의 경련 정도도 더 심하였다(64.1% vs. 46.5%, P=0.006). 흉통이 있었던 그룹이 흉통이 없었던 그룹보다 허혈성 심전도 변화의 빈도가 더 높았다(14.7% vs. 7.5%, P=0.007). 또한 흉통이 있었던 그룹이 관상동맥 경련이 다발성으로 발생하는 경우가 많았고 (50.7% vs. 29.5%, P<0.001), 미만성으로 발생하는 경우가 많았고(87.1% vs. 75%, P<0.001), 관상동맥의 경련의 정도도 더 심하였다(51.6% vs. 43.5%, P=0.041). 결론: 아세틸 콜린 유발검사시 발생하는 허혈성 심전도 변화와 흉통은 관상동맥 경련의 정도와 경련이 발생하는 관상동맥 개수와 연관이 있다. Background: ECG changes and chest pain during acetylcholine (Ach) provocation tests may constitute important clinical parameters for Ach-induced endothelial dysfunction. We investigated the association between ischemic ECG changes and chest pain during the Ach-provocation test and angiographic characteristics of Ach-induced endothelial dysfunction. Methods: A total of 1,085 patients with anginal symptoms underwent diagnostic coronary angiography (CAG) and Ach-provocation tests. We compared angiographic characteristics of Ach-induced endothelial dysfunction according to the presence of ECG change and chest pain. Results: A total of 539 patients experienced Ach-induced endothelial dysfunction. Patients who experienced ECG change group suffered more frequent chest pain (78.1% vs. 60.8%, P=0.007), angiographically more frequent multiple coronary artery spasm (59.4% vs. 40.6%, P=0.004), and more severe coronary artery spasm (64.1% vs. 46.5%, P=0.006) than patients without ECG change. However, there was no difference in the length of endothelial dysfunction between the groups. The incidence of ischemic ECG changes in patients with chest pain was higher than in patients without chest pain (14.7% vs. 7.5%, P=0.007). Patients who experienced chest pain more often experienced multiple (50.7% vs. 29.5%, P<0.001), diffuse (87.1% vs. 75%, P<0.001), and severe coronary artery spasm (51.6% vs. 43.5%, P=0.041) than patients without chest pain. Conclusion: Ischemic ECG changes and chest pain during the Ach-provocation test are associated with multi-vessel involvement and severe coronary artery spasm. Chest pain is associated with the length of endothelial dysfunction, but ischemic ECG change is not.

        급성심근경색증에서 Urokinase 정맥 투여에 대한 임상적 경험

        임도선(Do Sum Lim),김영훈(Young Hoon Kim),나승운(Seung Woon Rha),안정천(Jeong Cheon Ahn),송우혁(Woo Hyuck Song),박창규(Chang Gyu Park),서홍석(Hong Seog Seo),심완주(Wan Joo Shim),오동주(Dong Joo Oh),노영무(Young Moo Ro) 대한내과학회 1997 대한내과학회지 Vol.53 No.1

        N/A Objectives: The most important therapeutic strategy in acute myocardial infarction(AMI) is early recanalization of infarct-related artery(IRA). In Korea the commonly used method for recanalization is urokinase infusion in early phase of disease. But total dosage and method of urokinase infusion are still arbitary. Thus this study was undertaken to evaluate the patency rate of infarct-related artery by urokinase in AMI patients. Methods: 42 acute myocardial infarction patients were treated with intravenous urokinase(40.000U/kg in 32 patients, 3,00,000U in 10 patients). IRA patency was evaluated with coronary angiography at 90 minutes and 7-10 days after intravenous urokinase. The clinical findings and coronary angiographic findings according to dose of urokinase or pain to time for urokinase injection were analysed prospectively. Results: Mean pain to Door time was 251 minutes and door to urokinase time was 74 minutes. Early patiency of IRA was 61.8%(21/42) and no difference was observed between the dosage of intravenous urokinase. In open IRA group(21 patients) the reocclusion was not observed at 7-10 days later. The ejection fraction on admission was similiar in patent or non-patent IRA group, but follow up ejection fraction was significantly lower in closed IRA group than open IRA group(P=0.0185). Life- threatened bleeding complications were developed in 2 cases(4.8%, I intracranial hemorrhage, 1 gastrointestinal bleeding). Conclusion: IRA patency was achieved in 61.8% of acute myocardial infarction by intravenous urokinase as evaluated by coronary angiography. The patency of IRA at 90 minutes was important in preserving the global left ventricular function in early recovery phase of acute myocardial infarction. But large, prospective study may be needed to determine optimal and effective intravenous urokinase dosage in acute myocardial infarction.

        관상동맥질환의 독립적 표지자로서의 대동맥 팽창성

        김응주(Eung Ju Kim),서홍석(Hong Seog Seo),임성윤(Sung Yoon Lim),김미(Mina Kim),진오(Jin Oh Na),최철웅(Cheol Ung Choi),김진원(Jin Won Kim),임홍의(Hong Euy Lim),나승운(Seung-Woon Rha),박창규(Chang Gyu Park),오동주(Dong Joo Oh) 대한임상노인의학회 2009 대한임상노인의학회지 Vol.10 No.4

        연구배경: 대동맥의 탄성은 관상동맥질환 환자에서 비정상인 것으로 알려져 있으나, 대동맥 탄성도의 지표들 중 하나인 대동맥 팽창성이 관상동맥질환과 독립적으로 연관되어 있는 지는 확실치 않다. 방법: 관상동맥 조영술을 받은 일련의 373명 중 급성관동맥 증후군, 과거 심근경색, 중등도 이상의 의미 있는 판막질환, 좌심실 구혈율 40% 미만, 심방세동, 관상동맥 성형술이나 관상동맥 우회술의 병력이 있는 사람들을 제외한 총 305명(관상동맥질환 환자군 107명, 대조군 198명)을 관찰하였다. 심장초음파를 이용하여 대동맥 판막으로부터 3 cm 원위부의 상행대동맥 직경을 측정한 후 2×(대동맥 내경의 변화)/(확장기 대동맥 내경×맥압) 공식으로 대동맥 팽창성(cm²×dyn⁻¹×10⁻⁶)을 구하였다. 결과: 수축기, 확장기 혈압과 맥박수는 양 군간 차이가 없었으나 대동맥 팽창성은 환자군이 유의하게 대조군 보다 낮았다(1.15±0.30 vs. 3.00±0.25, P<0.001). 다변량분석에서 대동맥 팽창성은 나이, 성, 고혈압, 당뇨병, 고지혈증과 흡연을 보정하고도 관상동맥질환과 유의한 상관성(P<0.001)을 보였다. 더욱이 대동맥 팽창성은 1∼3혈관질환으로 표현한 관상동맥질환의 심한 정도와 반비례하는 양상이었다(P<0.001). 결론: 대동맥 팽창성은 관상동맥질환의 독립적 위험 표지자이며 관상동맥질환의 심한 정도와 상관있는 것으로 생각된다. Background: Elastic properties of aorta have been known to be abnormal in patients with coronary artery disease (CAD). However, aortic distensibility (AD), one of the elasticity indexes, has not been ascertained whether it is independently associated with CAD. Methods: We prospectively enrolled 305 subjects (107 patients with CAD and 198 patients without it) among 373 consecutive patients undergoing coronary angiography for the assessment of suspected CAD. Patients with acute coronary syndrome, previous myocardial infarction, valvular heart disease more than mild, left ventricular ejection fraction <40%, atrial fibrillation, and history of coronary intervention or surgery were excluded. Aortic diameters were measured at a level 3 cm above the aortic valve using echocardiography. AD (cm²×dyn⁻¹×10⁻⁶) was calculated from the aortic diameters and brachial artery pressure using the formula: 2×(change in aortic diameter)/(diastolic aortic diameter ×pulse pressure). Results: Systolic, diastolic blood pressure and pulse rate were similar in both CAD and control subjects. AD was significantly lower in patients with CAD than controls (1.15±0.30 vs. 3.00±0.25, P<0.001). In multivariate analysis, AD remained significantly associated with CAD (P<0.001) after adjustment for age, gender, hypertension, diabetes, hyperlipidemia and smoking. Moreover, AD showed significant inverse relationship with the severity of CAD, expressed as one-, two-, and three-vessel disease (P<0.001). Conclusion: Our findings suggest that impaired AD is an independent risk marker for CAD, as well as significantly associated with the severity of CAD.

        양측 슬와동맥 혈전 폐색증에서 성공적인 내혈관 치료 1예

        박수형 ( Soo Hyung Park ),장원영 ( Won Young Jang ),현학준 ( Hak Jun Hyun ),최성지 ( Seong Ji Choi ),김민정 ( Min Jung Kim ),나승운 ( Seung-woon Rha ) 대한내과학회 2018 대한내과학회지 Vol.93 No.4

        본 증례에서는, 좌심실박출률이 저하된 확장심근병과 관상동맥 질환이 있는 환자에서 심첨부의 혈전이 심장초음파로 확인이 되었고, 이것이 밀초동맥색전증의 원인으로 생각되었다. 이후 혈관조영술 및 혈관내 스텐트를 통하여 기계적혈전흡인술, 풍선확장술 그리고 동맥내 혈전용해제 투여를 한 후 혈관 폐색 부위의 성공적인 재개통을 이룰 수 있었다. 전신적인 혈전색전증의 일환으로 다발성, 양측성 슬와동맥혈전색전증이 발생한 것은 비교적 드문 경우이며, 이러한 상황에서 수술이나 Fogarty의 풍선 카테터를 이용한 혈전제거술을 하지 않고 경피적 중재 시술을 통하여 효과적으로 치료한 경우로 이에 보고하는 바이다. The popliteal artery is a relatively short vascular structure, but acute occlusion can decrease blood flow into the lower extremities and cause subsequent critical limb ischemia, amputation, and even mortality. Further, peripheral artery disease patients frequently have combined cardio-cerebrovascular disease. Here, we report a rare case of sudden bilateral thrombotic total occlusion in the popliteal arteries of a patient with dilated cardiomyopathy and left ventricular thrombi. This patient has been successfully managed by endovascular therapy and subsequent intra-arterial thrombolytic therapy. (Korean J Med 2018;93:393-397)

        Cushing's syndrome associated with nodular adrenal glands will be divided into four main categories: adrenal adenoma, adrenal carcinoma, primary pigmented nodular adrenal dysplasia (PPNAD) and macronodular adrenal hyperplasia(MAH). The term macronodular adrenal hyperplasia is restricted to the presence of multiple nodules visible to the naked eye, ranging in size from 0.5 to 7.0 cm. We report a case of Cushings syndrome caused by bilateral macronodular adrenal hyperplasia (MAH). A 45-year-old man presented with Cushingoid features, hypertension and diabetes mellitus. Urine free cortisol was 449.9 mmol/day(27-276) and were not suppressed after administration of low-dose and high-dose dexamethasone. Plasma ACTH was very low(1.87 pmol/L(18)) and was not stimulated by administration of ovine CRH. In abdominal CT, both adrenal glands were markedly enlarged and nodular in appearance. Pituitary MRI showed no abnormal finding. Bilateral adrenalectomy was done. Histologic examination revealed multiple nodules and internodular hyperplasia. This case and other reports suggested that because of variable biochemical, radiologic and pathologic findings, macronodular adrenal hyperplasia represents a heterogeneous group of patients with varying degrees of adrenal autonomy (J Kor Soc Endocrinol 11:523~530, 1996)
