목 적 : 가와사끼병은 회복기나 사춘기와 성인기에 정상인보다 동맥경화의 위험성이 크다고 알려져 있어 이에 대한 조기진단과 관리가 매우 중요하다. 이에 저자들은 가와사끼병을 앓은 학동기나 학동전기 아동을 대상으로 복부대동맥의 신전성과 동맥경화의 조기예측인자인 지질 성분과 혈액학적 염증 지표들을 조사하여 가와사끼병의 장기 관리의 기초적인 자료로 활용하고자 본 연구를 시행하였다. 방 법 : 충남대학교병원 소아과에서 1998년 6월부터 2005년 3월까지 가와사끼병으로 치료받았던 28명을 관상동맥병변이 지속되고 있는 8명(1군)과 관상동맥병변이 없었던 20명(2군)으로 나누어 조사하였고, 가와사끼병이 있는 군과 연령, 체중, 신장이 일치하는 건강한 소아 30명을 대조군(3군)으로 하였다. 지질 성분과 혈액학적 염증지표를 측정하였고, 혈압은 자동혈압계를 이용하여 앙와위에서 15분 안정 후 3회 측정하여 그 평균치를 구하였다. 심장초음파검사는 심실기능과 관상동맥병변 등을 조사하였으며 복부의 subxiphoid long axis view에서 복부 대동맥의 최대 수축기 직경과 최소 이완기직경을 측정하였다. 결 과 : 호모시스테인은 환자군과 대조군 사이에 유의한 차이(P=0.008)가 있었으나 지질성분에서는 차이가 없었다. 복부대동맥의 경직도를 나타내는 지표인 Ep, $Ep^*$는 대조군에 비해 환자군에서 유의(P<0.05)하게 증가되었으며, 관상동맥병변의 유무에 따라 비교해 보면 관상동맥병변이 있는 군(1군)에서는 유의한 차이를 보였으나 관상동맥병변이 없는 군(2군)은 대조군과 유의한 차이가 없었다. 또한 1군과 2군을 비교해 보았을 때 Ep, $Ep^*$이 1군에서 유의하게 증가해 있었다. 결 론 : 가와사끼병을 앓은 후 조기동맥경화의 변화는 학동기에도 나타날 수 있으며, 이는 관상동맥병변이 있는 환자에서 더욱 현저하다. 이에 대한 선별검사로 성인에서 이용되고 있는 동맥경화의 조기예측인자인 지질 성분과 혈액학적 염증지표들 및 혈관의 물리적 특성(PWV, FMD) 이외에도 복부 대동맥경직도가 유용하게 사용될 수 있을 것으로 생각된다.

We present a rare case of a patient with aortoiliac occlusive disease on the background of type A crossed renal ectopia, for whom open surgical intervention was required. Aortic exposure in patients with concomitant crossed renal ectopia can present technical challenges to the vascular surgeon. The knowledge of variations in the ectopic renal blood supply is of paramount importance when performing surgery to treat this condition and affects the choice of surgical exposure. We present and discuss the operative details of our patient and outline an approach to this subset of patients.

Williams syndrome (WS) is a developmental disorder characterized by vascular abnormalities such as thickening of the vascular media layer in medium- and large-sized arteries. Supravalvular aortic stenosis (SVAS) and peripheral pulmonary artery stenosis (PPAS) are common vascular abnormalities in WS. The natural course of SVAS and PPAS is variable, and the timing of surgery or intervention is determined according to the progression of vascular stenosis. In our patient, SVAS and PPAS showed rapid concurrent progression within two weeks after birth. We report the early manifestation of SVAS and PPAS in the neonatal period and describe the surgical treatment for stenosis relief.

Atherosclerosis, slow progressing inflammatory lesion in arteries, is one of the major causes of cardiovascular diseases. As mortality due to cardiovascular disease keeps increasing in Korea, researches on pathological mechanism of atherosclerosis may be beneficial in fighting against cardiovascular diseases. It is known that migration and MMP-9 secretion of Vascular Smooth Muscle Cell(VSMC) play a significant part in pathogenesis of atherosclerosis, although detailed mechanism of entire process is not clarified. We investigated whether the seeds of Trichosanthes kirilowii maxim (TS), inhibit migration and MMP-9 production of HASMC(human aortic SMC), which were induced by TNF-${\alpha}$ treatment. Migration assay showed that TS inhibited the migration of HASMC induced by TNF-${\alpha}$, in dose dependent manner. Also by Zymography MMP-9 production of HASMC was found to be reduced by TS, both in time and in dose dependent manner. Western blotting results suggest TS suppress activity of MAPkinases.

Background: We evaluated the operative outcomes of an extra-anatomic bypass from the ascending aorta to the abdominal aorta in patients with type II or III Takayasu arteritis (TA) with mid-aortic syndrome. Methods: From 1988 to 2014, 8 patients with type II (n=2) or III (n=6) TA underwent an ascending aorta to abdominal aorta bypass. The mean patient age was $43.5{\pm}12.2years$ and the mean peak pressure gradient between the upper and lower extremities was $54.8{\pm}39.0mm\;Hg$. The median follow-up duration was 54.4 months (range, 17.8 to 177.4 months). Results: There were no cases of operative mortality. The mean peak pressure gradient significantly decreased to $-2.4{\pm}32.3mm\;Hg$ (p=0.017 compared to the preoperative value). Late death occurred in 2 patients. The symptoms of upper extremity hypertension and claudication improved in all patients. The bypass grafts were patent at $47.1{\pm}58.9months$ in 7 patients who underwent follow-up imaging studies. Conclusion: An extra-anatomic ascending aorta to abdominal aorta bypass could be an effective treatment option for severe aortic steno-occlusive disease in patients with type II or III TA, with favorable early and long-term outcomes.

Background: Pulsatility of cerebral arteries and aortic stiffness have been associated with white matter hyperintensities (WMH). We explored which is better correlated with the severity of WMH in a population with acute lacunar infarct. Methods: We included patients with acute small subcortical infarcts who underwent transcranial Doppler (TCD) and brachial ankle pulse wave velocity (baPWV). Exclusion criteria were any stenosis or occlusion on major cerebral arteries on magnetic resonance angiography; poor temporal insonation windows; ankle brachial index < 0.9; and atrial fibrillation. We assessed the performance of the pulsatility index of bilateral middle cerebral arteries (PI-MCA) and baPWV for predicting moderate-to-severe WMH, defined as an Age Related White Matter Changes score > 5, and then sought to find independent predictors using binary logistic regression analysis. Results: Eighty-three patients (56 males, mean age $61.5{\pm}11.4$) participated in the study. Uni-variate analysis showed old age and high PI-MCA were significantly correlated with moderate-to-severe WMH. However, baPWV was not associated with the severity of WMH. Multivariate analysis revealed old age (odds ratio per 1-year increase, 1.068; p = 0.044) and upper tertile of PI-MCA (odds ratio, 5.138; p = 0.049) were independently associated with moderate-to-severe WMH. Receiver-operating characteristics showed PI-MCA differentiated those with and without moderate-to-severe WMH with an area under the curve of 0.719. Conclusions: PI-MCA derived from TCD was better correlated with the severity of WMH than baPWV in a population with lacunar infarction. Pulsatility of cerebral arteries may better predict cerebral small vessel disease than the aortic stiffness index.

Aortic arch syndrome is an unusual disease entity characterized by the narrowing or obliteration of major branches of the arch of the aorta regardless of etiology. We have experienced 2 cases. One of them was 22 years old office girl with 3 months history of headache, intermittent syncope and weakness and claudication on left arm especially during her physical exercise. On physical examination, pulseless on left antecubital and radial artery and blood pressure on left arm was inable to check and coldness with weakness were noted on the same side. Aortic angiography reealed 34% narrowing of left subclavian artery as that of right. But both common carotid artery and both axillary arterial patency were relatively good. Through right supraclavicular and left axillary incision, bypass graft with Gore-tex prosthesis (I.D. 6mm, Length 25 cm) was implanted from right subclavian artery on 2cm distal to origin of right common carotid arery to left axillary artery distal to axillary fossa. End to side anastomosis with preservation of left subclavian artery was done. Postoperative state was stable with blood pressure of 110/70 mmHg on left arm and palpable antecubital and radial pulsation. Another one was 41 year old male patient with 8 months history of pain and numbness on right upper arm and shoulder. On admission, right arm blood pressure was 110/80 mmHg, left arm was 160/110 mmHg, but other physical findings had no abnormalities. Angiography revealed segmental narrowing of right axillary artery on the beginning with 2 cm in length. Operative treatment with right wupraclavicular and right axillary incision, bypass graft with great saphenous vein (Length; 15 cm) from right subclavian artery between scalenus anticus and medius to axillary artery at distal end of axillary fossa was done. The authors report two cases of Aortic arch syndrome treated with bypass graft using Autograft or Gore-tex with good result.
