The treatment of isolated calcified lesions involving the popliteal artery are demanding and they often require stent placement to achieve acceptable luminal gain. This study evaluates the safety and performance of the orbital atherectomy system (Cardiovascular Systems Inc.) and percutaneous transluminal angioplasty with a drug-coated balloon (PTA-DCB) for the treatment of chronic atherosclerotic lesions within the popliteal artery segment. From November 2018 to November 2019, a series of six patients with Rutherford classification stage III peripheral arterial disease with isolated, focal, calcified occlusions of the popliteal artery were treated with orbital atherectomy followed by PTA-DCB. No embolic protection devices were used. The technical success rate was 100%, the primary patency rate was 100% at 7.0 (±4.2) months of follow-up. The Rutherford classification improved in all patients from stage III to stage II and the mean ankle brachial pressure index after the procedure was 0.97 (±0.08), with a preoperative mean ankle brachial pressure index of 0.69 (±0.21). In one instance, spasm was noted in a distal arterial bed and it was successfully treated with local nitroglycerine. No distal embolisation, perforation or aneurysmal degeneration was observed. During follow-up there were no deaths, major amputations or revascularisation of target lesions. The use of orbital atherectomy system in combination with PTA-DCB was found to be safe and effective in modifying focal, chronic, calcified plaques in the popliteal artery segment in these six cases.

Background: Peripheral artery disease (PAD) affecting the femoropopliteal artery is treated by endovascular interventions [2, 5, 13] increasingly. Aim of the study was to evaluate mid-term efficacy and patency of long stents in the superficial femoral and popliteal artery. Patients and methods: Between September 2006 and September 2007 103 patients received 128 stents for endovascular treatment of femoropopliteal vascular stenosis or occlusion. Clinical and hemodynamic parameters were collected. Risk factors, popliteal involvement and TASC classification, were documented and evaluated. Results: Immediate outcome was satisfactory with a technical success rate of 100 %. After a mean follow-up period of 21 months, primary patency was 83.6 %. Potential risk factor analysis for restenosis and fracture demonstrated hypertension to have borderline significance (P = 0.06). In normotensive patients no restenosis occurred. Further pre-conditions, e.g. smoking, metabolic syndrome, age, gender and previous intervention did not show any influence on restenosis or stent fracture. TASC C and D lesion had similar patency rates compared to TASC A and B lesions. Most of the restenoses (13 out of 16) were observed within the first six months of follow-up. Six stent fracture were observed (4.7 %). Conclusions: Long stents had convincing results after endovascular treatment of the femoropopliteal PAD. The used stent was an efficacious endovascular tool for long athersclerotic lesions in the superficial femoral and popliteal artery. Fracture rate was low with an incidence of 4.7 %. Most restenoses occurred within the first six months so that careful follow-up would be necessary.

Background: Even though many types of stents have been tested in superficial femoral artery (SFA) and popliteal artery (PA), the vast majority of these devices have provided an unsatisfactory outcome, probably due their unsuitable anatomical and physiological characteristics. The Supera peripheral stent (Abbott Vascular, Santa Rosa, CA, USA) is a braided interwoven nitinol device specifically designed for treating atherosclerotic lesions of the femoro-popliteal segment. The aim of this multicenter retrospective study was to describe the effectiveness of Supera stents in the management of femoral-popliteal atherosclerotic lesions and to critically analyze our findings in the context of current and past literature.Design and Methods: In this study we enrolled only patients who satisfied the inclusion criteria: 1) patients affected by chronic obstructive arterial disease (COAD) grade II, as per Rutherford classification; 2) patients treated with endovascular revascularization and Supera stent implantation in the femoro-popliteal axis. We retrospectively analyzed the Doppler Ultra-sound (US) follow-up at 12-24 and 36 month in order to detect the vascular occlusions. The primary patency, primary patency assisted and TLR were described statistically analyzed by survival analysis and the demographic data, clinical data, device safety following stenting were described as frequency and mean value.Results: 105 endovascular procedures on 99 patients for femoro-popliteal stenting with Supera were performed in four Italian hospitals. The median follow-up was 39 months (range 6-72), with primary patency rate of 83.1%, 74.3% and 69.5% at 12, 24 and 36 months after the procedure. The primary patency assisted was 89.9%, 76.8% and 73.4% in the same period, while the freedom from TLR values were 92.7%, 91.5% and 89.5% at 12, 24 and 36 months after the procedure, respectively. The mortality rate recorded at 12 months from the Supera implantation was 2.8% (3 out of 99 patients enrolled).Conclusions: Our data were in agreement with the current literature, showing the non-inferiority Supera stent in relation to the other stent available. Supera stent showed an excellent safety, effectiveness profile and high durability for the treatment of PAD patients with femoro-popliteal artery disease.

Purpose: To investigate outcomes of drug-coated balloon (DCB) angioplasty in endovascular interventions including or restricted to the popliteal artery. Methods: A retrospective analysis was conducted of 266 patients [median age 72 years, interquartile range (IQR) 62, 78; 166 men] treated with DCB angioplasty in 281 de novo lesions including the popliteal artery between December 2011 and January 2015 at a single center. The median lesion length was 270 mm (IQR 150, 373). The study outcomes were primary patency and predictors of restenosis [reported as the hazard ratio (HR) with 95% confidence interval (CI)]. Results: The primary patency was 77.4% at a median 12.2 months (IQR 5.7, 18.8). Independent variables associated with restenosis included baseline Rutherford category (HR 1.36, 95% CI 1.05 to 1.77, p=0.02), reference vessel diameter (HR 0.77, 95% CI 0.63 to 0.95, p=0.02), dissection (HR 1.69, 95% CI 1.022.79, p=0.04), and standard nitinol stent use (HR 2.08, 95% CI 1.14 to 3.79, p=0.02). Conclusion: Outcomes after DCB angioplasty in lesions including the popliteal artery were acceptable compared with previous studies. Further investigation with long-term follow-up is needed to confirm these results.

Objectives Endovascular repair (ER) of popliteal artery aneurysm (PAA) is an alternative to open repair. However, there is no standardized protocol for when to opt for ER and the decision is therefore at the discretion of the clinician. This study aims to evaluate the adherence to the Instruction For Use (IFU) in patients undergoing ER for PAA and factors associated with stent graft patency at one year. Methods The adherence to IFU provided by the manufacturer in 55 patients treated with Gore Viabahn® Endoprosthesis with Heparin Bioactive Surface for PAA between 2009 and 2019 were retrospectively analyzed. Duplex follow-up was performed at 30 days and one year. Results The two groups of patients treated within ( n = 10) and not within ( n = 45) IFU did not differ in patient demographics, diagnostic assessment, treatment or outcome. Forty-five patients (81.8%) received stent graft placement with at least one deviation according to IFU. Distal oversizing >20% was the most frequent deviation against IFU ( n = 22, 40.0%). Primary patency at one year was 72%. Diameter size difference >1 mm between overlapping stent grafts (6/14 [43%], p = 0.013) and renal insufficiency (5/12 [42%], p = 0.0086) were associated with lower primary patency at one year. Age-adjusted analysis of tortuosity index (HR 1.78/SD, 95% CI 1.17–2.71; p = 0.0071) and maximal PAA angle (HR 1.73/SD, 95% CI 1.018–2.95; p = 0.043) were associated with major amputation/mortality at end of follow-up. Conclusion The majority of patients undergoing ER for PAA were not treated within IFU. Diameter size difference >1 mm between overlapping stent grafts was associated with a higher loss of primary patency at one year. Multi-center studies with larger sample size and long-term follow up of patency are warranted.

Objective This study aimed to introduce and evaluate the safety and efficacy of the relay puncture technique in patients with complicated lower extremity arterial diseases. Methods A total of 21 patients (16 male and five female patients; median age: 68.5 years old), who had suffered from lower extremity arterial diseases between December 2014 and July 2017, were retrospectively collected. For all patients, the contralateral femoral artery was not available for puncture access, and the length of the devices was too short for the brachial artery approach. Therefore, the relay puncture technique, in which the first puncture was performed on the brachial artery, followed by an antegrade puncture on the femoral artery, was used to accomplish the endovascular therapy. Percutaneous transluminal angioplasty and/or percutaneous transluminal stenting were/was used to assess the efficacy of the relay puncture technique. The ankle–brachial index (ABI) and Rutherford clinical classification were used to evaluate the improvement of symptoms after treatment. Patients were followed up for 1, 3, 6, and 12 months, and annually (mean: 16.6 months) after discharge. Results The relay puncture treatment had a 100% technical success rate, and immediately decreased the ischemic symptoms of patients after the procedure. The ABI significantly increased from 0.33 ± 0.18 to 0.75 ± 0.21 at the 1-year follow-up time point (P < 0.05). No serious complications occurred during the follow-up period. The 1-year primary patency rate was 71.43%. Conclusion The relay puncture technique is a feasible technique in the hands of experienced and skilled equipment operators for the treatment of lower extremity arterial diseases, when the contralateral femoral artery is not available for puncture, and the length of the device is too short to treat the distal lesion of the femoral artery and popliteal artery through the brachial artery approach.

Abstract OBJECTIVES Coarctation of the aorta (CoA) in adolescents and adults is relatively rare. Several operative techniques have been reported, but there is no consensus. METHODS From November 1994 to July 2018, a total of 24 adolescents and adults underwent CoA repair. The mean age at operation was 29.9 ± 15.1; 19 (79%) patients were older than 18. Sixteen (67%) patients had arterial hypertension, 5 (21%) patients had bicuspid aortic valve, 4 (17%) patients had descending aneurysm, 2 (8%) patients had ascending aneurysm, 2 (8%) patients had patent ductus arteriosus and 1 (4%) patient had atrial septal defect. Three patients had prior surgery (2 CoA repair, 1 ventricular septal defect repair). RESULTS Surgical corrections included extra-anatomical bypasses in 12 (50%) patients (9: left subclavian artery to descending aorta bypass, 2 proximal-to-distal coarctation bypasses, 1 ascending-to-descending aortic bypass), end-to-end anastomosis in 6 (25%) patients, resections and interpositions of a tube graft in 5 (21%) patients and arch augmentation with a tube graft in 1 (4%) patient. The mean follow-up duration was 6.2 ± 5.1 years. No mortality was observed. No patient required reoperation or reintervention. The mean upper extremity systolic pressure significantly decreased from 142.4 ± 30.3 mmHg preoperatively to 121.1 ± 15.9 mmHg postoperatively (P = 0.002). Arterial pressure gradient between upper and lower extremities significantly decreased from 50.0 ± 21.8 mmHg preoperatively to 9.7 ± 13.5 mmHg postoperatively (P &lt; 0.001). Among patients undergoing left subclavian artery to descending aorta bypass, 8 patients underwent ankle brachial pressure index evaluation. Postoperative mean right- and left-sided ankle brachial pressure index were 0.96 ± 0.16 and 0.94 ± 0.11, respectively. All grafts were patent at the last follow-up. CONCLUSIONS CoA repair in adolescents and adults showed good outcomes. Left subclavian artery to descending aorta bypass grafting is safe and effective for managing CoA in adolescents and adults.

Objective The aim of this study was to compare the drug-eluting balloon with self-expanding interwoven nitinol stent deployment in patients with complex femoropopliteal lesions. Methods We retrospectively identified patients at our clinic with complex femoropopliteal artery lesions treated either with self-expanding interwoven nitinol stent or drug-eluting balloon. All patients had ankle-brachial index measured before and after the intervention, and regular clinical follow-up with Doppler ultrasonography was performed at six months and one year. Patients underwent peripheral angiography if needed. Results From April 2012 to July 2015, 107 patients with complex femoropopliteal lesions treated with using self-expanding interwoven nitinol stent ( N = 49, mean length 143.5 mm, mean follow-up of 14.1 ± 3.7 months) or drug-eluting balloon ( N = 58, mean length 140.6 mm, mean follow-up of 13.8 ± 4.1 months). The technical success rate was 100% in Supera® and 96.6% in drug-eluting balloon group. There were seven restenosis in self-expanding interwoven nitinol stent (SUS) group (84.8% patency) and 11 restenosis in drug-eluting balloon group (79.2% patency). A significant increase in the ankle-brachial index in both groups after intervention demonstrated a hemodynamic success (SUS group 0.45 ± 0.06, drug-eluting balloon group 0.43 ± 0.07). The mean Rutherford Becker Class significantly decreased in both groups after a follow-up of 12 months (SUS group 0.70 ± 0.73, drug-eluting balloon group 0.74 ± 0.75). Conclusion Deploying drug-eluting balloon or self-expanding interwoven nitinol stent in patients with complex femoropopliteal lesions are both safe and effective with high patency rates with no statistical difference for one-year primary patency rates between them.

AbstractBackground and aimThere is only a limited number of major publications on the outcome of interventions for isolated popliteal artery stenosis. The purpose of this study was to report our results on mid-term patency and predictors of restenosis.Patients and methodsThis single-center retrospective study included 61 symptomatic patients (males, N = 33; median age, 65.1 years [IQR, 60.7–71.9 years]; Rutherford grade 4–6, N = 14) with at least two patent crural arteries, whose atherosclerotic stenoses/occlusions were treated with percutaneous transluminal angioplasty (PTA) or stenting (using self-expanding bare-metal Astron Pulsar stents) between 2011 and 2018.ResultsTwenty-six patients had PTA, while 35 underwent stenting. The median follow-up was 29 months (IQR, 10–47 months). The primary patency rates were not significantly different (P = 0.629) between PTA and stenting groups. Restenosis developed in nine patients (34.6%) in the PTA group, and in 12 (34.3%) in the stenting group. Restenotic lesions required re-intervention in nine cases (100%) in the PTA group, and in eight (66.7%) in the stenting group. Restenosis developed significantly less frequently (P = 0.010) in patients with a popliteal/P1 stent; the primary patency rates were also significantly better (P = 0.018) in patients with a popliteal/P1 stent when compared to popliteal/P2 plus multi-segment stents. Cox regression analysis identified lesion location as a predictor of in-stent restenosis (HR, 2.5; 95% CI, 1.2–5.5; P = 0.019).ConclusionStenting was not superior when compared to PTA (if selective stenting was not considered as loss of patency). Follow-up should be more thorough in patients undergoing popliteal/P2 or multi-segment stenting.

Objective: To compare the antegrade and retrograde approaches, in terms of access site complications and long-term patency in subjects undergoing EVT for symptomatic SFA or popliteal artery stenosis or occlusions. Methods: All consecutive patients who underwent retrograde recanalization for partial stenosis or chronic total occlusion of the SFA or PA at 2 centers were enrolled in this retrospective analysis. Subjects were divided into 2 groups, according to the approach selected for EVT as antegrade approach group or retrograde approach group. The rate of primary patency, which was defined as the lack of restenosis at the target lesion, was the primary outcome measure, during the follow-up evaluations. The rate of procedural complications, including hematoma, bleeding, and distal embolism, were secondary outcome measures. Results: A significant improvement occurred in ABI, following the intervention in both the antegrade approach group [0.7 (0.3 - 1.1) versus 0.85 (0.4 - 1.3), P < 0.001] and retrograde approach group [0.5 (0.3 - 1.1) versus 0.8 (0.3 - 1.3), P < .001]. The primary patency rate at the 1st, 6th, 12th and 24th months of the intervention in the antegrade approach group were 94.85%, 83.82%, 74.26%, and 66.91%, respectively. The primary patency rate at the 1st, 6th, 12th, and 24th months of the intervention in the retrograde approach group were 93.33%, 86.67%, 84.44%, and 71.11%, respectively. The groups were similar with respect to the primary patency rates. The rate of complications, including hematoma, bleeding, and distal embolization was similar in the 2 groups. Conclusion: Antegrade approach and retrograde approach provide a similar safety profile in the EVT of SFA and popliteal artery stenosis and occlusion. The primary patency rates at the 1st, 6th, 12th, and 24th months of follow up also were similar in the 2 groups. However, the significant difference in the lesion characteristics of the subjects undergoing retrograde or antegrade approach complicates the ability to reach a clear conclusion, regarding the superiority of one technique over the other.

Aims: Stenting of the popliteal artery (PA) is generally considered inappropriate due to the high mechanical stress and bending of the artery during knee flexion. Nevertheless, vessel recoil remains problematic following angioplasty procedure for chronic total occlusions (CTOs) and adjunctive stenting may be required. The purpose of this study is to compare balloon angioplasty alone versus bailout stenting for isolated CTO of the PA. Materials and Methods: Between March 2012 and October 2016, 43 patients were treated with percutaneous transluminal angioplasty with balloon alone (PTA, n = 16) or bailout stenting percutaneous transluminal angioplasty and stenting (PTAS, n = 27) for de novo CTO of PA. There was no statistically significant difference between both groups with regard to patient demographics and lesions characteristics (calcification severity and lesion length). The median lesion lengths were 67 mm (39.5-78.5) in the PTA group and 94 mm (50-114) in the PTAS group ( p = 0.14). The primary outcome measure was primary patency; secondary outcomes were technical success, primary assisted patency, major amputation, and increased Rutherford classification. Results: Technical success rate was 37% and 96.3% in the PTA and PTAS groups, respectively. There was no statistical difference in 12-month primary patency rate (65.8% versus 58.7%; p = 0.15) and primary assisted patency at 12 months (75.2 versus 69.2; p = 0.47) between the 2 groups. Freedom from target lesion revascularization at 12 months was not significantly different, with 85.7% and 81.6% ( p = 0.2) in the PTA and PTAS groups, respectively. One amputation occurred in the PTA group. Conclusion: This small cohort suggests that stenting as a bailout procedure in CTO of the PA provides similar results to successful balloon angioplasty. Stenting should only be performed after suboptimal balloon angioplasty with vessel recoil. Due to the large lost to follow-up, strong evidence of a therapy over the other cannot be formulated. Larger studies with longer and stronger follow-up are needed to confirm those results.
