Abstract
Purpose: To evaluate duplex ultrasonography (DUS) in the assessment of femoropopliteal stenoses comparing a single native stenosis (SNS) to multisegmental native stenoses (MNS). Methods: Among the 1284 patients treated for atherosclerotic occlusive disease involving the femoropopliteal segment between November 2002 and November 2012, 139 patients (97 men; mean age 68±8 years) with 142 SNS or 143 MNS in 79 and 60 patients, respectively, were eligible for this retrospective analysis. The peak systolic velocity ratios with proximal (PSVRprox) and distal (PSVRdist) reference for the 285 lesions were compared with their respective angiographic stenosis grade as measured by 2 independent readers using quantitative vascular analysis to ensure objectivity. Receiver operating characteristic curve analysis was used to evaluate sensitivity, specificity, and the optimal thresholds of PSV and PSVR for detection of stenoses by grade (>50%, >70%, or >80% diameter stenosis). The area under the curve (AUC) values of dependent and independent receiver operating characteristic curves were compared. Results: For SNS, correlation of PSVRprox to diameter stenosis (R=0.88) was higher (p<0.001) than the correlation for MNS (R=0.78). In the SNS group, the AUC for detecting a >50% (0.99±0.01), >70% (0.98±0.01), and >80% (0.96±0.01) stenosis with PSVRprox was significantly higher than in the MNS group [AUC50% 0.93±0.02 (p=0.01), AUC70% 0.92±0.02 (p=0.02), and AUC80% 0.87±0.03 (p=0.003)]. The optimal thresholds for detecting >50%, >70%, and >80% stenoses for SNS using PSVRprox were 2.6, 3.3, and 3.9, respectively. For MNS, the optimal thresholds of PSVRprox were 2.6, 3.4, and 3.9, respectively, with respective sensitivities of 87%, 81%, and 75%; respective specificities of 93%, 90%, and 82%; negative predictive values of 45%, 64%, and 74%; and positive predictive values of 99%, 95%, and 83%. Conclusion: DUS is an optimal tool for quantification of SNS. However, a multisegment setting has a significant negative impact on the quantification of femoropopliteal artery stenosis.

Abstract
PURPOSE To determine the clinical and technical outcomes following endovascular therapy for aortoiliac occlusive disease, including complex reconstruction of the aortic bifurcation. METHODS A retrospective database search identified 1184 consecutive patients (864 men; mean age 64±10 years) who underwent 1712 procedures to treat target lesions in the distal aorta and iliac arteries from September 1996 to December 2006. The intended strategy was to open only one femoral access site primarily, so a second puncture was needed only for the kissing balloon technique at the aortic bifurcation. The primary endpoint was a 1-year duplex-based primary patency; secondary endpoints included acute technical success (residual stenosis <30%), secondary patency, and target lesion revascularization (TLR). Results were stratified by lesion morphology, which was classified according to the TransAtlantic Inter-Society Consensus (TASC II) document. RESULTS Most of the interventions were done in the iliac arteries (n=1337); 292 cases involved the aortic bifurcation, and 83 cases were in the distal aorta/aortic bifurcation. The mean follow-up was 3.24 years (range 0-12.7). In the entire study cohort, the 12- and 24-month restenosis, TLR, and primary/secondary patency rates did not differ among TASC II A-D subgroups. The symptom-driven TLR in the entire cohort was 8% and 9% at the 12- and 24-month follow-up, leading to secondary patency rates of 96% and 91% in the entire cohort. Outcomes for complex interventions in the distal aorta or aortic bifurcation did not differ significantly compared to the total cohort. The overall survival without restenosis, amputation, or surgery in TASC II subgroups A+B was higher (69.6%±1.5%) compared to TASC II C+D lesions (62.8%±1.9%, p=0.001). CONCLUSION The indication for percutaneous intervention in aortoiliac occlusive disease can be extended to complex TASC C and D lesions in experienced endovascular centers, even if complex reconstruction of the distal aorta or the aortic bifurcation is indicated.

Drug-coated balloon angioplasty after directional atherectomy improves outcome in restenotic femoropopliteal arteries. J Vasc Surg 2013; 58:682-6. [PMID: 23755977 DOI: 10.1016/j.jvs.2013.02.019] [Citation(s) in RCA: 72] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2011] [Revised: 01/14/2013] [Accepted: 02/12/2013] [Indexed: 11/25/2022]
Abstract
BACKGROUND Restenosis remains an unresolved problem despite different treatment modalities and new stent technology in femoropopliteal arteries. No standard therapy has proven to provide acceptable outcome data for this entity. Directional atherectomy alone did not result in satisfactory long-term patency rates. The outcome might be improved in conjunction with drug-coated balloon angioplasty. METHODS In this retrospective study, restenotic lesions of the femoropopliteal arteries were treated with directed atherectomy in 89 lesions of consecutive patients (58% male; mean age, 69 ± 11 years). All patients received adjunctive treatment with conventional balloon percutaneous angioplasty (PTA; n = 60) or drug-coated balloon angioplasty (DCB; n = 29). RESULTS Lesion location was in the stent (DCB [n = 27] vs PTA [n = 36]) and in native restenotic vessels (DCB [n = 2] vs PTA [n = 25]). The 1-year Kaplan-Meier freedom from restenosis estimates (95% confidence intervals) in the DCB and PTA groups were 84.7% (70.9%-98.5%) and 43.8% (30.5%-57.1%), respectively. In a multivariable Cox model for restenosis, DCB treatment had a hazard ratio (95% confidence interval) of 0.28 (0.12-0.66; P = .0036) compared with the PTA group. In the multivariable model for procedural success, the effect of treatment did not differ between PTA and DCB (P = .134). CONCLUSIONS The combination of directed atherectomy with adjunctive DCB is associated with a better event-free survival at 12 months of follow-up compared with PTA after directed atherectomy.

Abstract
BACKGROUND To report feasibility and safety of the Pathway PV™ Atherectomy System during percutaneous peripheral vascular interventions of in-stent restenosis. PATIENTS AND METHODS 33 patients (66.7 % men; mean age 68.7 years; 39.4 % diabetics) with symptomatic infrainguinal in-stent restenosis were enrolled at 5 study sites. Primary study endpoint was the 30-day serious adverse event (SAE) rate. At one study site a subgroup of 13 patients was scheduled for additional follow-up examinations with duplex. RESULTS Forty lesions with a mean lesion length of 85.7 mm (range 6 - 370 mm) were treated including total occlusions (20 %) and infrapopliteal lesions (5 %). In sixteen target lesions (40 %) procedural success was reached with atherectomy alone, 23 lesions (57.5 %) received adjunctive percutaneous transluminal angioplasty to obtain a sufficient angiographic result. Freedom from device-related SAEs was 100 %. Overall there were 11 unexpected adverse events in 11 patients, two of which were serious (retroperitoneal bleeding and access site infection). The ankle-brachial index increased significantly from 0.65 ± 0.13 at baseline to 0.82 ± 0.15 at 30 days. Mean Rutherford category improved from 2.8 ± 0.7 at baseline to 1.0 ± 1.2. In the subgroup with longer follow- up primary patency was 33 % after 12 months and 25 % after 24 months. Secondary patency was 92 % after 12 and 24 months. CONCLUSIONS The use of the Pathway PV™ System during percutaneous peripheral vascular interventions of in-stent restenosis appears to be feasible and safe but does not seem to offer a sustainable solution regarding long term patency. A combination with drug eluting balloon angioplasty could be an interesting option and should be evaluated in further clinical trials.

Abstract
OBJECTIVES The study investigated the long-term clinical impact of sirolimus-eluting stents (SES) in comparison with bare-metal stents (BMS) in treatment of focal infrapopliteal lesions. BACKGROUND There is evidence that SES reduce the risk of restenosis after percutaneous infrapopliteal artery revascularization. No data from randomized trials are available concerning the clinical impact of this finding during long-term follow-up. METHODS The study extended the follow-up period of a prospective, randomized, multicenter, double-blind trial comparing polymer-free SES with placebo-coated BMS in the treatment of focal infrapopliteal de novo lesions. The main study endpoint was the event-free survival rate defined as freedom from target limb amputation, target vessel revascularization, myocardial infarction, and death. Secondary endpoints include amputation rates, target vessel revascularization, and changes in Rutherford-Becker class. RESULTS The trial included 161 patients. The mean target lesion length was 31 ± 9 mm. Thirty-five (23.3%) patients died during a mean follow-up period of 1,016 ± 132 days. The event-free survival rate was 65.8% in the SES group and 44.6% in the BMS group (log-rank p = 0.02). Amputation rates were 2.6% and 12.2% (p = 0.03), and target vessel revascularization rates were 9.2% and 20% (p = 0.06), respectively. The median (interquartile range) improvement in Rutherford-Becker class was -2 (-3 to -1) in the SES group and -1 (-2 to 0) in the BMS group, respectively (p = 0.006). CONCLUSIONS Long-term event-free survival, amputation rates, and changes in Rutherford-Becker class after treatment of focal infrapopliteal lesions are significantly improved with SES in comparison with BMS.

Abstract
AIM This paper presents the recent data of the largest series (20 patients) of endovascularly treated patients and the first long term data of 9 patients with severe aortoiliac occlusive disease. METHODS Between 2003 and 2012, 20 consecutive patients (14 men; 70 %) with Leriche syndrome underwent recanalization with solely endovascular means at our centre. The treatment strategy comprised the antegrade (transbrachial) recanalization of the occluded segments followed by retrograde (transfemoral) angioplasty with selective stent placement in the infrarenal aorta and primary stent placement in the iliac arteries. Before discharge, after 30 days and every year after the procedure, a clinical, as well as a duplex ultrasonographic examination including measurement of the ankle-brachial index was done. RESULTS Bilateral success was achieved in 17 patients (85%). Unilateral success was achieved in three patients (15%). In one patient (5%) an early reocclusion of the stented segments occurred, necessitating bypass grafting. In nine patients long term data were evaluated. Here, the ankle brachial index (ABI) significantly increased (0.85 ± 0.15 vs. 0.51 ± 0.11 at baseline; P=0.002). Compared to baseline, the difference in the distribution of Rutherford category and the improvement of walking capacity were statistically significant (P=0.0006, P=0.01, respectively). CONCLUSION This study shows the feasibility of solely endovascular management of severe aortoiliac occlusive disease with a high rate of success and low rate of complications. Significant clinical improvement of patients in long term follow up makes the endovascular approach a viable alternative to open surgery.

Abstract
AIMS Preliminary reports indicate that sirolimus-eluting stents reduce the risk of restenosis after percutaneous infrapopliteal artery revascularization. We conducted a prospective, randomized, multi-centre, double-blind trial comparing a polymer-free sirolimus-eluting stent with a placebo-coated bare-metal stent in patients with either intermittent claudication or critical limb ischaemia who had a de-novo lesion in an infrapopliteal artery. METHODS AND RESULTS 161 patients were included in this trial. The mean target lesion length was 31 ± 9 mm. The main study endpoint was the 1-year primary patency rate, defined as freedom from in-stent-restenosis (luminal narrowing of ≥50%) detected with duplex ultrasound if not appropriate with angiography. Secondary endpoints included the 6-month primary patency rate, secondary patency rate, and changes in Rutherford-Becker classification after 1 year. Twenty-five (15.5%) patients died during the follow-up period. One hundred and twenty-five patients reached the 1-year examinations. The 1-year primary patency rate was significantly higher in the sirolimus-eluting stent group (80.6%) than in the bare-metal stent group (55.6%, P= 0.004), and the 1-year secondary patency rates were 91.9 and 71.4% (P= 0.005), respectively. The median (interquartile range) change in Rutherford-Becker classification after 1 year was -2 (-3 to -1) in the sirolimus-eluting stent group and -1 (-2 to 0) in the bare-metal stent group, respectively (P= 0.004). CONCLUSION Mid-term patency rates of focal infrapopliteal lesions are substantially improved with sirolimus-eluting stent compared with bare-metal stent. Corresponding to the technical results, the changes in Rutherford-Becker classification reveal a significant advantage for the sirolimus-eluting stent.

Abstract
The present study was carried out to provide information about outcome of the Jetstream atherectomy device for treatment of infrainguinal arteries. From February 2006 to February 2007, 172 patients with Rutherford class 1 to 5 lower limb ischemia were enrolled at 9 study sites. The endpoints were evaluation of quality of life according to the walking impairment questionnaire (WIQ) besides technical parameters. In the total study cohort, the WIQ scale maintained improved up to 12-month follow-up. Furthermore, target lesion revascularization rate was 26% (42/162), ankle-brachial index (ABI) increased from 0.59 ± 0.21 at baseline to 0.82 ± 0.27 ( P < 0.05), and mean Rutherford class dropped from 3.0 ± 0.9 at baseline to 1.5 ± 1.3 at 1 year ( P < .05). The results of this prospective, multicenter, clinical study demonstrate that the Jetstream atherectomy device is a potential treatment alternative for the endovascular management to improve clinical outcome in patients with peripheral arterial occlusive disease.

Abstract
Background The constantly growing amount of different kinds of colloid fluids necessitates comparative investigations with regards to the safety and effectivity in clinical use of these preparations. Hence we compared three colloid fluids in an observational study. The objective was the exploration of the influence of these three colloids on blood coagulation, hemodynamics and renal function of the cardiac surgical patient. Methods We included 90 patients undergoing an elective open-heart surgery with the use of the heart-lung machine and observed them consecutively. Group 1 [gelatin 4% (n = 30)], Group 2 [HES 200/0,5 (n = 30)] and Group 3 [HES 130/0,42 (n = 30)]. We measured the perioperative volume replacement, the administration of blood- and coagulation-products, the application of catecholamines, the renal function, blood gas and the platelet aggregation using multiplate electrode analyzer (Multiplate®, Dynabyte medical, Munich, Germany). Results The gelatin-group needed significantly more norepinephrine than the HES 130/0.42 group. The responsible surgeon considered the blood coagulation in the HES 200/0.5 group most frequently as impaired. Furthermore we saw a significant decrease in platelet function in the HES 200/0.5 group when performing the multiplate®-analysis (ADP-and COL-test). HES 130/0.4 as well as gelatin 4% showed no significant change in platelet function. The gelatin-group and the HES 200/0.5 needed significantly more aprotinine than the HES 130/0.4 group. We saw no significant difference with regards to administration of blood and coagulation products between the three groups. The urinary excretion during the intervention was significantly higher in the HES 200/0.5 group and in the gelatin group than in the HES 130/0.4 group. Conclusions Our results confirm the lower stabilizing effect of gelatin on circulation during fluid resuscitation. The blood coagulation was mostly impaired due to HES 200/0.5 confirmed by the multiplate®-analysis as well as by different clinical findings.

Abstract
We conducted a three-arm, parallel-group, randomized, controlled trial to compare the effects of rosiglitazone and physical exercise on endothelial function in patients with coronary artery disease and impaired fasting glucose or impaired glucose tolerance over a 6-month period. Group A received rosiglitazone tablets 8 mg daily (n = 16), group B underwent a structured physical exercise programme (n = 15) and group C served as a control group (n = 12). At baseline and after 6 months, brachial artery ultrasound imaging was performed to assess reactive flow-mediated dilation (FMD). Rosiglitazone treatment and exercise both led to significant improvements in insulin resistance at 6 months, whereas no change was observed in control patients. FMD improved significantly in physical exercise patients, whereas no change could be observed in patients receiving rosiglitazone or in the control group. Between-group comparisons also showed a significant relative improvement in FMD in exercise patients compared with rosiglitazone.

Abstract
Chronic mesenteric ischemia (CMI) is most likely caused by atherosclerosis and less frequently by external compression and vasculitis. Symptomatic CMI is an uncommon, potentially under-diagnosed condition caused by fixed stenoses or occlusion of, in most conditions, at least two visceral arteries. If only one of the three major bowel-providing arteries — the celiac trunk, and the superior and inferior mesenteric arteries — is affected, the patient is usually asymptomatic due to a tight collateral network. The only exception is the celiac artery compression syndrome which represents primarily a compression syndrome of celiac plexus nerves by the arcuate ligament in conjunction with a compression of the celiac trunk. CMI of atherosclerotic origin is associated with a high morbidity and mortality. During the last decade, endovascular revascularization has replaced surgical revascularization as the therapy of choice in most centers. This article reviews the most relevant clinical aspects of the disease and the current practice of diagnosis and treatment of CMI.
