Antegrade Approach

Objective: Popliteal artery puncture, which makes possible the use of lower profile sheaths and devices, has gained popularity as an alternative to the antegrade approach, due to the reduction in vascular complications at the access site. The present study aimed to analyze the safety of the procedure and long-term patency of the superficial femoral artery (SFA) and popliteal artery (PA) and in subjects undergoing recanalization with the popliteal retrograde approach. Methods: Forty-three subjects, who underwent endovascular therapy (EVT) of the SFA or PA with retrograde popliteal approach, were enrolled in this retrospective study. The decision for the retrograde approach was made according to pre-intervention CT angiography results (severe calcification and relatively long CTO segment) in 20 of the subjects. The remaining 23 subjects underwent SFA or PA recanalization with the retrograde approach, due to failed antegrade recanalization attempt. All patients underwent color duplex ultrasound at the first, sixth, 12th, and 24th months to determine patency. The rate of procedural complications, including hematoma, bleeding, and distal embolism, were recorded for all subjects. Results: Technical success was achieved in all cases. Access site complications, including hematoma and bleeding, were observed in 2 subjects (4.66%). Transfusion or surgical treatments were not required in any cases with access site complications. The acute success rate was defined as the recovery of good blood flow evaluated by angiography after EVT was 100%. Distal embolization, which did not cause any limitations in distal flow, occurred in 1 subject (2.33%). Ankle-brachial index (ABI) calculated at 1 month post-intervention was significantly higher than pre-intervention ABI [0.9 (0.59 - 1.3) versus 0.7 (0.4 - 1.1), P < .001]. Patency rates, as determined by ultrasonographic assessment at post-interventional first, sixth, 12th, and 24th months, were 100%, 95.34%, 88.37%, and 86.04%, respectively. Conclusion: Our findings demonstrate that retrograde popliteal artery puncture can be used as a safe and effective technique for recanalization of SFA and PA stenosis and occlusions. The retrograde popliteal approach provides excellent long-term primary patency rates.

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.

Stent Stenosis

Background: Advances in stent technology have widened the field of indications for stent treatment of femoro-popliteal artery lesions, however the use of stents in bending arterial segments is restricted because some first- and second-generation nitinol stent designs did not respond well to the mechanical forces of femoro-popliteal segments in motion which pose a substantial risk of stent fracture inducing in-stent-stenosis. New generation nitinol stents are supposed to overcome these limitations but long-term results are rare. Patients and methods: In forty-five patients (mean age 68 y, range 50 - 85) with peripheral arterial disease (TASC II A-C, Rutherford category 2 - 5) forty-six lesions of the superficial femoral artery (37) or popliteal artery (9) were treated [25 high-grade stenoses, mean length 53 mm (range 30 - 145 mm); 21 chronic total occlusions, mean length 74 mm (range 30 - 180 mm)]. 74 % of lesions were located in the mobile bending arterial segments in the distal femoral or the popliteal segment. Clinical reevaluation performed at discharge, at 6, 12, 24, and 36 months included at least the measurement of ankle-brachial index (ABI) and duplex sonography. Results: Procedural success rate was 100 %. At 6, 12, 24, and 36 months, cumulative primary patency rate was 93.5 %, 84.8 %, 80.5 %, and 74.3 % (SE<10); freedom from target lesion revascularization rate was 95.7 %, 89.2 %, 84.9 %, and 79.3 % (SE<10); Rutherford category and ABI improved in all patients and clinical success was maintained in more than 85 % of patients. Conclusions: Sustained technical and clinical success and good clinical long-term results were achieved with Misago™ nitinol stent implantation in femoro-popliteal lesions with moderate risk for in-stent-stenosis, and in the distal femoral and popliteal mobile segment.

The aim of this study was to evaluate the long-term outcomes of the surgical repair of popliteal artery aneurysms (PAAs), and to analyze the factors associated with graft patency. Between January 1980 and December 2013, 45 limbs were subjected to open surgical repair at Tokyo Medical and Dental Hospital. We retrospectively examined the patients' clinical characteristics, clinical symptoms, and aneurysm-related anatomy. Surgical procedures were performed through a posterior or medial approach using autologous vein or prosthetic graft. Surgical outcomes were evaluated by postoperative mortality, postoperative morbidity, graft patency, and limb salvage. During the study period, 45 limbs (35 patients; mean age, 60 years) underwent open surgical repair. A total of 25 limbs were treated through a posterior approach using 23 autologous vein grafts (AVGs) and 2 expanded polytetrafluoroethylene (ePTFE) grafts. The other 20 limbs were treated through a medial approach using 13 AVGs and 7 ePTFE grafts. During the mean follow-up period of 65 months, the primary patency rates at 1, 3, and 5 years were 88.0%, 75.7%, and 75.7%, respectively, and the limb salvage rates at 1, 3, and 5 years were 97.1%, 91.4%, and 91.4%, respectively. In the univariate analysis, the ligation and bypass grafting affected the primary patency rate significantly, and the ePTFE graft was associated with a poor primary patency in the multivariate analysis (hazard ratio, 17.8). The use of resection or endoaneurysmorrhaphy for PAAs and graft interposition with an AVG might be more effective for the open repair of PAAs.

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 The purpose of this study was to evaluate the results of combining superficial femoral artery endovascular therapy with distal bypass originating from the popliteal artery as a method of lower extremity revascularization in patients with chronic limb-threatening ischemia. Methods The records of patients undergoing combined superficial femoral artery endovascular therapy with popliteal-to-distal bypass for chronic limb-threatening ischemia from January 2014 to April 2020 at a single institution were retrospectively reviewed. The patients’ background, operative details, and long-term outcomes were analyzed. Results Fifty-two popliteal-to-distal bypasses with superficial femoral artery endovascular therapy were performed in 49 patients (33 men; mean age, 76 ± 9 years; diabetes mellitus, 80%; end-stage renal disease with hemodialysis, 47%). The Trans-Atlantic Inter-Society Consensus II classification of superficial femoral artery–popliteal lesion was “A” in 8 (15%) patients, “B” in 14 (27%) patients, “C” in 24 (46%) patients, and “D” in 6 (12%) patients. The intervention for superficial femoral artery lesions was plain old balloon angioplasty in 4 patients, self-expandable nitinol stent in 15 patients, drug-coated balloon in 18 patients, drug-eluting stent in 4 patients, stent graft in 10 patients, and interwoven nitinol stent in 1 patient. Distal bypass originated from the above-knee popliteal artery in 9 (17%) limbs and the below-knee popliteal artery in 43 (83%) limbs. The most common outflow artery was the posterior tibial artery (44%). The mean follow-up period was 17 ± 17 months. The primary and secondary patency of the graft was 44% and 72%, respectively, at 1 year and 39% and 72%, respectively, at 3 years. Primary patency and freedom from clinical-driven target lesion revascularization of superficial femoral artery endovascular therapy lesions were 85% and 90%, respectively, at 1 year and 63% and 75%, respectively, at 3 years. Limb salvage was 97% at 1 year and 92% at 3 years. Wound healing was 67% at 6 months and 83% at 12 months. Conclusions Combined superficial femoral artery endovascular therapy with popliteal-to-distal bypass may be a promising approach for patients with chronic limb-threatening ischemia because of durable patency, acceptable wound healing, and good limb salvage.

Abstract Background: The iliac occlusive disease is usually treated with endovascular procedures in recent years. The effectiveness of different crossing approaches for these occlusions is not precisely known. We performed a retrospective study to explore the optimal crossing approach (antegrade versus retrograde) for iliac artery chronic total occlusions (CTOs) and to examine the long-term outcomes. Materials and Methods: We performed a study on 107 patients (116 iliac occlusive lesions, mean age 64.0±11.1, 88 men) who underwent an iliac CTO endovascular intervention attempted with the use of both crossing strategies but were managed with one final crossing approach between August 2012 and August 2018. Baseline data, procedural characteristics, and outcomes were described. A Cox proportional hazard model and Kaplan-Meier method were developed to assess the differences in the two crossing approaches in terms of the 1-year and 5-year primary patency rates, target lesion revascularization (TLR ) and major adverse limb events (MALEs ). Results: Common iliac artery (CIA ) lesions were more likely to be crossed successfully in the retrograde direction (6.8% for antegrade vs. 20.9% for retrograde, p=0.005), while lesions in the CIA/ external iliac artery (EIA ) were more prone to be crossed successfully in the antegrade direction (58.9% for antegrade vs. 39.5% for retrograde, p=0.016). There were no significant differences in the crossing approach for EIA lesions between the two groups. The two crossing approaches were associated with similar estimates of 1- and 5-year primary patency, TLR and MALE rates. Conclusion: The antegrade approach was associated with a higher rate of successful crossing in CIA/EIA CTO lesions, while the CIA-only CTOs were more likely to be crossed successfully with the retrograde approach.

ABSTRACT Use of the Femoral Vein as Insertion Site for Tunneled Hemodialysis Catheters The femoral vein provides an alternative access site for insertion of tunneled hemodialysis catheters when conventional sites are not available. Tunneled femoral hemodialysis catheters have low primary patency rates and significant complications. Catheter retraction is a unique and common problem. However, the use of the femoral vein remains acceptable in those patients who have limited options for long-term hemodialysis.

Introduction: Several factors related to lesion characteristics and endovascular therapy (EVT) procedures have been reported to affect primary patency after EVT. However, it is unknown why these factors were associated with primary patency. We hypothesized patency failure was related to poor blood flow in affected arteries. Methods: This retrospective study included 131 consecutive patients who had received EVT with bare metal stents for peripheral artery disease caused by femoropopliteal artery lesions. Based on the tertile post-EVT flow velocity of the superficial femoral artery (SFA), patients were divided into high ( n = 43), middle ( n = 44), and low ( n = 44) flow velocity groups. Flow velocity was measured using the frame count method. We measured incidence of major adverse limb events (MALE), composed of target lesion revascularization (TLR), non-TLR, and major amputation. Results: At a median follow-up period of 22.7 months, MALE had occurred in 7 (16.3%), 10 (22.7%), and 29 (65.9%) of patients from the high, middle, and low SFA flow velocity groups, respectively ( p < 0.001). Kaplan–Meier analysis showed incidence of MALE was significantly higher in the patients of low SFA flow velocity (log-rank test χ2 = 38.8, p < 0.001). Multivariate analysis found low SFA flow velocity to be an independent predictor for MALE (hazard ratio: 4.42; 95% CI: 2.27 to 8.60; p < 0.001) as was ankle–brachial index. Conclusion: Post-EVT SFA flow velocity for femoropopliteal artery lesions treated with bare metal stents is an independent predictor of limb patency. The frame count method for assessing arterial flow velocity is convenient and has potential for wide applications in EVT.
