Objective: Peripheral arterial disease (PAD) reduces functional activity and increases the rate of cardiovascular death in the elderly. Our study aimed to determine whether the presence of PAD in stroke patients affected the progression of disability or death one year after discharge. Methods: From April 2012 to March 2013, consecutive first stroke patients above 50 years of age without known PAD were enrolled. PAD was defined as a low ankle-brachial index (less than 0.9) measured by an automatic device. Clinical data associated with the stroke were collected from medical records. Disability in stroke patients was evaluated with the modified Rankin scale (mRS) on discharge day and one year after the index stroke. Progression of disability was defined as an increase in mRS more than one level at one year. Results: Among the 526 patients, 238 had ischemic strokes and underwent ankle-brachial index (ABI) measurement. Of them, 192 patients were included. In univariate analysis, age, dyslipidemia, discharge mRS, low-density lipoprotein cholesterol, D-dimer, homocysteine, internal carotid artery stenosis, posterior cerebral artery stenosis, and PAD were factors associated with worsening mRS. After adjustment for these factors in the logistic regression analysis, PAD was an independent factor associated with worsening mRS. In the analysis of one-year mortality, patients with PAD had a higher death rate, but PAD was not an independent factor after adjusting for other variables. Conclusions: The presence of PAD in stroke patients suggests a chance of disability progression, but may not be a predictor of death after one year.

Atherosclerosis*

Peripheral arterial disease (PAD) in patients with type 2 diabetes mellitus (T2DM) exhibits broad clinical characteristics and various consequences and is known as one of the major macrovascular complications of T2DM. Atherosclerosis is recognized as the most direct and important cause of PAD, but acute or chronic limb ischemia may be the result of various risk factors. In light of the increasing number of patients who undergo peripheral vascular procedures, the number of subjects who are exposed to the risks for PAD and related complications is increasing. In this review, we will discuss the clinical and epidemiological characteristics of PAD, as well as the clinical significance of PAD in T2DM subjects.

PURPOSE: High peritoneal transport status is known to be related with the cardiovascular risk. One of the hypotheses that explain the relationship between peritoneal permeability and atherosclerosis is chronic inflammation and endothelial dysfunction. Microalbuminuria is a well-known marker of endothelial dysfunction and a predictor of cardiovascular disease (CVD). We hypothesized that peritoneal albumin excretion, like microalbuminuria, may be related to the cardiovascular events and chronic inflammation in peritoneal dialysis (PD) patients. METHODS: We enrolled eighty-five patients who started PD. Pre-existing CVD was defined as angina, history of MI, cerebrovascular disease, or peripheral arterial disease. Modified peritoneal equilibration test was performed within 2 months. At that time, peritoneal albumin excretion, serum and dialysate IL-6, CRP were measured. RESULTS: The age was 49.5+/-14 years and male-to-female ratio was 1 to 3. Diabetes mellitus and CVD were present in 40% and 28%, respectively. The dialysate-to-plasma albumin (D/Palb) was correlated with D/P4 Cr (r= 0.552, p<0.001), and was higher in HA/H group than in LA/L group (0.19+/-0.008 vs. 0.12+/-0.005, p<0.001). D/Palb was closely correlated with the dialysate IL-6 (r=0.432, p< 0.001), but not with the serum IL-6 and CRP. There were no differences in the peritoneal albumin excretion with respect to the diabetic status or pre-existing CVD. CONCLUSION: The peritoneal albumin excretion was associated with peritoneal small solute transport and dialysate IL-6 in the new PD patients. Prospective studies will follow in order to verify the role of peritoneal albumin excretion as a predictor of cardiovascular events.

PURPOSE: The purpose of this study is to review the roll changes of surgical treatment for peripheral artery disease in endovascular era. METHODS: One hundred and twelve surgically treated cases of peripheral artery disease at a single institution during the period from 2006 to 2011 were studied retrospectively. The cases were divided into two groups of different time periods, one before 2009 (surgical period group) and the other from 2009 onward (endovascular period group). We analyzed the type and location of surgery as well as clinical characteristics of patients and treatment results. RESULTS: Fifty-three cases were for the surgical period group and 59 cases for the endovascular group. No difference in the demographic characteristics and the distribution of major atherosclerosis risk factors was found between the two groups. Additionally, the technical and functional success rate was similar in both groups. However, it is found that there were more acute cases in the endovascular period group than in the surgical period group. The number of cases in need of suprainguinal or below knee exposure was similar in both groups. In hybrid cases, suprainguinal or below knee exposures were more frequently needed during the former period than the latter period. CONCLUSION: The role of surgical treatment is currently in the process of changing. Surgical treatment seems to be a complementary alternative to endovascular treatment for chronic limb ischemia. However, it still seems to play a major role for acute limb ischemia.

PURPOSE: Endovascular therapy (ET) for peripheral arterial occlusive disease has increased dramatically in the past decade. ET is currently being performed by different specialists with available resources, with some of these resources being far superior to others, yet there have been no studies comparing the interventional outcomes according to the varying resources. The aim of this study was to analyze the outcomes of ET for superficial femoral artery (SFA) atherosclerosis using a mobile C-arm, in comparison to a historical control group. METHODS: Between March 2009 and December 2010, ET for SFA atherosclerosis was performed in 54 limbs from 47 patients using a mobile C-arm in the operation theater (mobile group). In contrast, a historical group for comparison consisted of 60 patients, for whom ET for SFA atherosclerosis was performed in 76 limbs using a fixed C-arm in the angiographic suite, between July 2003 and May 2008 (fixed group). The outcomes of ET for both groups were retrospectively analyzed by a medical chart review. RESULTS: There was no statistically significant difference in gender, age, risk factors, Trans-Atlantic Inter-Society Consensus (TASC) classification, intervention type, and postoperative blood creatinine levels between the two groups. However, procedural time was statistically higher in the mobile group. Patency rates at 1 year were 68.3% and 68.1% in the fixed and mobile group, respectively, which was not statistically significant. Subgroup analysis of 1 year patency rates for TASC A, B lesions and TASC C, D lesions were also similar. CONCLUSION: ET using the mobile C-arm in the operating theater is as effective as using the fixed C-arm, in the treatment of SFA atherosclerosis in terms of the technical success, patency, and early postoperative outcomes.

Diabetes is associated with increased risk of cardiovascular disease, with atherosclerosis responsible for most associated morbidity and mortality. Atherosclerosis often causes acute thrombotic events through plaque rupture and formation of platelet-rich thrombi. The principal clinical manifestations of atherosclerosis are coronary artery disease, ischemic stroke, and peripheral arterial disease. Endothelial dysfunction, oxidative stress, and low-grade inflammation are key features in the pathophysiology of atherosclerosis.

PURPOSE: CT angiography (CTA) is established as a standard method for the evaluation of patients with peripheral arterial disease. However, there are some drawbacks including overestimation of stenotic lesions as well as dye toxicity and allergic reactions and renal function impairment. Arterial waveform analysis (AWA) is widely accepted as a diagnostic as well as a screening tool in the vascular laboratory. The purpose of this study was to determine the diagnostic accuracy of the AWA compared to the CTA. METHOD: One hundred thirty-eight AWA procedures were performed among symptomatic patients in our laboratory between October 2004 and February 2007. Sixty patients were entered into the study; they were eligible to have AWA and CTA synchronously. There were 5 women and 55 men with an average age of 64 years. The disease entities were atherosclerosis in 53, Burger's disease in three, popliteal entrapment in 2, arterial embolism in 1 and vascular trauma in one. Continuous-wave Doppler velocity waveforms were recorded at the common femoral, popliteal and dorsal pedal and posterior tibial arterial levels with compression cuffs. Four hundred and eighty segmental interpretations were analyzed and compared with the CTA findings. RESULT: The sensitivity of the AWA to detect iliac, femoropopliteal and tibial lesions were 93.8%, 64.4% and 88.4% respectively. The specificity of the AWA for the iliac, femoropopliteal and tibial lesions were 87.3%, 93.4% and 95.6% respectively. Overall, the accuracy of the AWA was 88.9% compared to the CT findings. Additional exercise AWA improved the results from 82.8 % to 88.6% for the overall sensitivity of the AWA. The 20 false positives included technical problems in 14 and reference errors (CTA) in six that were due to calcifications. There were 33 false negatives mostly from cases with stenosis and good collaterals. CONCLUSION: The results of this study showed that the AWA was a valuable method for the prediction of hemodynamically significant arterial lesions. The addition of highly skilled operators and a protocol including a high thigh cuff application might improve the accuracy of this diagnostic method.

PURPOSE: In the present study, the effects of autologous peripheral blood mononuclear cells (PBMNC) transplantation after granulocyte colony stimulation factor (G-CSF)-induced mobilization was investigated in patient with severe peripheral arterial disease. METHOD: 4 cases were enrolled: 3 cases are atherosclerosis obliterance and 1 case is thromboangitis obliterance. Following administration of G-CSF (10microgram/kg, maximum 600microgram), 4 times for 4 days. PBMNC were harvest and injected via femoral artery to vascular foot bed. RESULT: No serious complication was observed during G-CSF injection, harvest and injection. Improvement in the ankle brachial pressure index was seen in all patients at 4 weeks and ischemic ulcer improved in 2 of 3 patients. Using of pain control decreased in all cases and increased blood flow at 99 m-Tc perfusion scan in 2 of 2 patients. CONCLUSION: These favorable outcomes strongly suggest a therapeutic impact of transplantation PBMNC in clinical setting.
