  • 대퇴슬와동맥의 말초동맥폐쇄질환은 일반적으로 죽상경화증에 의해 발생하며, 질병의 정도에 따라 간헐적 파행에서부터 심각한 사지 허혈 또는 조직 손상에 이르는 다양한 증상으로 나타날 수 있다. 따라서, 증상을 개선하고 사지를 형태적, 기능적으로 보존하기 위해서는 적절한 치료가 필요하다. 대퇴슬와동맥 질환에서 시행되는 대표적인 인터벤션 치료로는 혈관 성형술, 스텐트 삽입술, 죽종절제술 등이 있다. 수년에 걸쳐, 혈관 내 재개통술은 최소 침습적이라는 이점과 더불어 시술 방법 및 사용 기기의 지속적인 발전을 토대로 말초동맥폐쇄질환의 치료에 널리 시행되고 있다. 이번 종설에서는 대퇴슬와동맥 질환의 다양한 혈관 내 치료 방법에 대해 소개하고, 문헌 고찰을 통해 현재까지 나온 임상 연구의 결과들을 논의하며, 대퇴슬와동맥질환의 치료에 적용되는 시술 방법에 대한 영상을 제시하여 독자의 이해를 돕고자 한다.

  • Arterial adventitial cystic disease is an uncommon type of non-atherosclerotic peripheral vessel disease. Most cases of arterial adventitial cystic disease occur in the popliteal arteries; however, fewer cases have been reported in the femoral arteries. A 59-year-old male patient visited the hospital with a complaint of a swelling on the lower extremity that had begun two months earlier. Suspecting deep vein thrombosis based on a physical examination and ultrasonography from another hospital, tests were performed. Magnetic resonance imaging (MRI) was performed for exact diagnosis because venous adventitial cystic disease was suspected by computed tomography venography. The MRI indicated venous adventitial cystic disease as well. Thus, a cystic mass excision was performed. In the end, a cystic mass compressing the common femoral vein that originated from the common femoral artery was diagnosed based on the macroscopic findings. This case is reported because blood circulation in the vein was impeded due to arterial adventitial cystic disease, and the symptoms improved after the cystic mass excision and polytetrafluoroethylene roofing angioplasty.

  • Background : The ankle brachial pressure index (ABI) is a simple, useful method for diagnosing peripheral artery disease (PAD). Although the ABI is an objective diagnostic method, it has limited reliability in certain scenarios. The aim of the present study was to determine the accuracy and reliability of the toe brachial index (TBI) as a diagnostic tool for detecting stenosis in PAD, associated with normal or low ABI values. Methods : ABI and TBI values were measured in 15 patients with diabetic gangrene who were suspected of having lower extremity arterial insufficiency. The ABI and TBI values were measured using a device that allowed the simultaneous measurement of systolic blood pressure in the upper and lower extremities. In addition, the ABI and TBI values were compared pre- and post-angiography. Results : Patients with an ABI of 0.9-1.3 showed almost no difference between the 2 measurements. The patients with TBI >0.6 had no arterial insufficiency. The patients with TBI <0.6 required vascular intervention with ballooning. After the angiography, the gangrenous wounds decreased in size more rapidly than they did prior to the intervention. Conclusions : Our findings suggest that TBI is the method of choice for evaluating lower limb perfusion disorders. This result requires further studies of TBI in a larger number of patients. Future long-term studies should therefore evaluate the utility of TBI as a means of screening for PAD and the present findings should be regarded as preliminary outcomes.

  • There was no significant difference in morbidity and mortality between those that received simultaneous operation for coronary artery disease and peripheral vascular disease versus those that received coronary artery bypass graft alone. Simultaneous operation is also cost effective. A 46 year-old patient with resting chest pain and intermittent claudication was diagnosed as unstable angina and Leriche's syndrome. We performed simultaneous revascularization for coronary artery stenosis with internal mammary artery and right gastroepiploic artery and a bifurcated vascular graft interposition between in the aorta, left common iliac and right femoral arteries for Leriche's syndrome. The postoperative coronary angiogram and aortogram revealed a good patency of the arterial conduits and vascular graft. He has been followed for 12 months without any problem.

  • In this study, photoplethysmography(PPG) was suggested as a way to replace the ankle-brachial index(ABI) in diagnosing PAD. The method using the PPG was presented for the simplification of the PAD diagnosis method which was used before. And the index related to the health condition of the artery from the PPG measured in both big toes of the subjects through the experiment was drawn. The indexes showing the significant relativeness in the Pearson correlation analysis with the ABI were the stiffness index(SI), reflection index(RI); it was confirmed each of them had the correlation coefficient of 0.688, and 0.637 at p < 0.05. The explanation ability of the linear regression equation derived using ABI, SI and RI was 52.5%. The explanation ability of the secondary curve regression equation derived using ABI, squared SI was 54.7%. It is expected to provide patients with significant results and draw the index associated with PAD by measuring PPG easily in the real life instead of the ambulatory care field.

  • Peripheral arterial disease, because of it's significant and prolonged morbidity and related mortality is a major medical and surgical problem. Contrast angiogram remains the essential standard for the anatomic demonstration of disease. It does not, however, provide data suitable for quantification or any evaluation of the microcirculation. For these reasons, radionuclide studies are playing an increasingly important role by not only confirming the diagnosis and offering objective data on the physiologic significance of anatomic lesions, but by offering prognosis of healing and prediction of therapeutic results. In addition, radionuclide procedures offer means to safely and repeatedly monitor response to therapy and long term follow up. The object of this study was to evaluate the clinical availability of $^{201}T1$ perfusion scan in patients with peripheral arterial diseases. We performed $^{201}T1$ perfusion scans in patients with five Buerger' s disease (10 legs), six DM gangrenes (12 legs) and classified three perfusion pattern groups. Finally we compared treatment modalities among each groups and compaired T1-201 perfusion scan findings with angiographic findings in six patients with Buerger's disease. The results were as follows: 1) Seven legs showed increased perfusion in stress image and normal or increased perfusion in resting image (type 1). Six legs showed decreased perfusion in stress image and improved in resting image (type II). Of total 13 legs, only 1 leg needed to amputation. 2) Three legs showed decreased perfusion in stress and resting image (type III), and subsequently all cases were received surgical amputation. 3) In six Buerger's disease patients, there were disagreements in two patients (2 legs) between $^{201}T1$ scan and angiography, in which angiograms were normal but $^{201}T1$ scans showed 'type II' perfusion patterns.

  • Ginkgo biloba (G. biloba) extract is a widely used phytomedicine for the oral treatment of peripheral vascular disease. Cilostazol is a synthetic antiplatelet and vasodilating agent for the treatment of intermittent claudication resulting from peripheral arterial disease. It is likely to use concomitantly G. biloba extract and cilostazol for the treatment of peripheral arterial disease, which raises a concern of increasing their adverse effects of herbal-drug interactions. To clarify any possible herbal-drug interaction between G. biloba extract and cilostazol, the effect of the G. biloba extract on the pharmacokinetics of cilostazol was investigated. As cilostazol is known to be eliminated mainly by cytochrome P450 (CYP)-mediated metabolism, we investigated the effects of G. biloba extract on the human CYP enzyme activities and the effect of G. biloba extract on the pharmacokinetics of cilostazol after co-administration of the two agents to male beagle dogs. The G. biloba extract inhibited more or less CYP2C8, CYP2C9, and CYP2C19 enzyme activities in the in vitro microsomal study with $IC_{50}$ values of 30.8, 60.5, and $25.2{\mu}g/ml$, respectively. In the pharmacokinetic study, co-administration with the G. biloba extract had no significant effect on the pharmacokinetics of cilostazol in dogs, although CYP2C has been reported to be responsible for the metabolism of cilostazol. In conclusion, these results suggest that there may not be a pharmacokinetic interaction between G. biloba extract and cilostazol.

  • 발을 향해 가는 혈류의 중요한 길목인 무릎 밑 동맥은 다리 혈관 중 가장 가늘며, 협착 등의 병변이 발생하거나 폐쇄가 발생하게 되면 중증하지허혈을 유발할 수 있다. 중증하지허혈이란 말초동맥 질환의 가장 심한 임상 양상 중 하나로서 휴지기 동통, 족부궤양 또는 괴저의 형태로 나타난다. 일반적으로 동맥경화 질환의 진행은 미만성으로 나타나며 대다수의 환자에서 무릎 밑 동맥을 침범한다. 치료의 목표는 동맥혈류 재개통과 사지구제이다. 기술적으로 가능한 경우, 그리고 환자가 걷지 못하는 상태가 아니라면 중증하지허혈이 있는 환자는 혈관의 재개통이 즉시 이루어져야 한다. 따라서 혈관 내 치료는 무릎 밑 동맥을 포함한 모든 환자의 표준 치료가 될 것이며, 혈관재건술을 시행하는 외과의의 임상적 역할은 줄어들 것이다.
