Abstract
BACKGROUND Despite improved patency with newer-generation nitinol stents, one-half of patients will require secondary interventions for in-stent restenosis (ISR). The best treatment strategy remains unclear. This study aimed to compare drug-coated balloons (DCBs) used alone or in association with excimer laser atherectomy (ELA) to simple percutaneous transluminal angioplasty (PTA) in the treatment of femoropopliteal-ISR. METHODS The INTACT trial is a multicenter, prospective, triple-arm randomized trial conducted across 14 centers from December 2015 to November 2019. Patients Rutherford Class 2-5 with ISR≥70% were followed-up for 18 months. The primary efficacy endpoint was recurrent ISR>70% by duplex ultrasound analysis. The primary safety endpoint was major adverse events (MAEs) defined as death, major amputation, or target lesion revascularization (TLR). RESULTS Around 134 subjects were randomized to PTA alone (n=41), PTA+DCB (n=43) or PTA+ELA+DCB (n=50). Procedural success was similar (p=.74), as was clinical success (p=.17). The number of recurrent ISR>70% decreased after PTA+ELA+DCB (30.0%; p=.04) and PTA+DCB (30.2%; p=.05) compared to PTA alone (51.2%). Primary patency was higher after PTA+ELA+DCB (log-rank p=.04) and PTA+DCB (log-rank p=.02) compared to PTA alone at 12 months (78.7% and 70.4% vs 61.5%) and 18 months (61.6% and 67.7% vs 37.3%). Freedom from MAEs was lower after PTA+DCB (27.9%) compared to PTA alone (53.7%; p=.02) but did not differ with PTA+ELA+DCB (40.0%). It was primarily driven by TLR; 2 major amputations occurred after PTA+ELA+DCB (4.0%; p=.18). CONCLUSION This independent study demonstrated a decrease in recurrent ISR>70% and increase in primary patency up to 18 months after PTA+ELA+DCB and PTA+DCB compared to PTA alone in the treatment of FP-ISR. It did not show an increase in MAEs but could have lacked power. CLINICAL IMPACT This multicenter, prospective, triple-arm randomized, controlled trial focuses on the results of adjunctive therapies, such as excimer laser atherectomy (ELA) and/or drug-coated balloons (DCBs) in the treatment of in-stent restenosis (ISR) in femoropopliteal lesions in 134 patients. It has the originality of being an independent study funded by a grant from the French Ministry of Health. This study confirms a significant decrease in recurrent ISR >70% and increase in primary patency up to 18 months after the use of ELA+DCB and DCBs compared to simple percutaneous transluminal angioplasty in the treatment of femoropopliteal ISR without an increase in major adverse events.

Comparison of mid-outcome among bare metal stent, atherectomy with or without drug-coated balloon angioplasty for femoropopliteal arterial occlusion. Sci Rep 2024; 14:63. [PMID: 38167567 PMCID: PMC10761798 DOI: 10.1038/s41598-023-50511-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Accepted: 12/20/2023] [Indexed: 01/05/2024] Open
Abstract
This study evaluated the outcomes of a bare metal stent (BMS), DCB alone, atherectomy plus a drug-coated balloon (AT + DCB) and AT alone for the treatment of femoropopliteal artery occlusion. Four groups were included in this retrospective cohort study: 119 patients underwent the BMS procedure, 89 patients underwent DCB alone, 52 patients underwent AT + DCB, and 61 patients underwent AT alone. Patients were followed-up at 1, 6, 12 and 24 months after the procedure, the clinical outcomes and complications were assessed, and the primary outcomes were primary patency and restenosis. AT + DCB showed a lower bailout stent, and BMS displayed a higher retrograde puncture, flow-limiting dissection and postdilation (p < 0.05). For all procedures, the walking distance, ABI and pain score post-procedure were significantly improved compared with the pre-procedure values (p < 0.001). The restenosis rate was higher in BMS (21.0%) and AT alone (24.6%) than in DCB (10.1%) alone and AT + DCB (11.5%) (p = 0.04); there was no difference in amputation or clinically driven target lesion revascularization among procedures. The primary patency rates were 77.7%, 89.4%, 88.0% and 73.7% in the BMS, DCB alone, AT + DCB and AT alone groups at 24 months, respectively (p = 0.03), while the secondary patency and main adverse events (stroke, MI and death) were similar. Proximal concavity, proximal target vessel diameter ≥ 5 mm, runoff number ≥ 2 and DCB use were protective factors for primary patency. Our results suggested that AT + DCB and DCB alone were associated with higher primary patency, and DCB devices (combined with/without AT) should be the preferred choice for FP lesions.

Abstract
Peripheral arterial occlusions are composed of variable amounts of thrombus. Endovascular techniques should initially address the variably aged thrombus prior to treating plaque (percutaneous transluminal angioplasty (PTA) ± stenting). This should ideally be accomplished in a single procedural session. Forty-four consecutive patients treated with the Pounce thrombectomy system (PTS) as captured in a retrospective database, who presented with acute (n = 18), subacute (n = 7), or chronic (n = 19) lower extremity ischemia, were treated and followed for a mean of 7 months. The peripheral occlusions were considered thrombus-dominant by the feel and ease of wire traversal. They were treated with PTS along with complimentary PTA/stenting when appropriate. The mean number of passes with PTS was 4.0 ± 2.7. Sixty-five percent (29/44) were successfully revascularized in a single setting with only 2 requiring concomitant thrombolysis for incomplete thrombus removal from the PTS target artery. An additional 15 patients (34%) had thrombolysis for tibial thrombus that was not attempted with PTS. PTA ± stenting after PTS occurred in 57% of limbs. Technical success was 83% and procedural success was 95%. Reintervention rate throughout follow-up was 22.7%. Major amputation occurred in 4.5%. Complications were limited to minor groin hematomas (n = 3). Outcomes were equally effective in patients with pre-existing stents or denovo arterial occlusions as evidenced with ankle brachial index improvement from 0.48 pre-to 0.93 postintervention and 0.95 at latest follow-up (P < 0.001). PTS coupled with PTA/stenting is expeditiously safe and effective in patients with thrombus-associated lower limb occlusion.

Abstract
BACKGROUND AND AIMS Endovascular recanalizaiton (ER) has been proven to be a feasible method for Thromboangiitis Obliterans (TAO). The aims of this study were to evaluate the effectiveness and safety of atherectomy for TAO compared to nonatherectomy ER in our center. METHODS Patients diagnosed as TAO were reviewed from January 2016 to June 2021 in our center. Basic characteristics of patients before ER and perioperative data were collected and compared between the atherectomy and nonatherectomy groups. The vascular event-free survival and limb salvage were calculated to evaluate the prognosis of TAO patients after ERs. Logistic Regression and Cox Regression were used to identify the risk factors for technical failure and prognosis, respectively. RESULTS Seventy-two TAO patients with 79 lower limbs who met the criteria were included in this report. Compared with the nonatherectomy group, no significant improvement was identified in ER technical success, vascular event-free survival, or limb salvage in the atherectomy group. The total technical success rate was 91.1% (atherectomy group, 95.2%; nonatherectomy group, 89.7%), and the multiple limb involvement (p = 0.005; odds ratio [OR], 28.16; confidence interval [CI], 3.28-241.55) was the independent risk factor for technical failure. The total vascular event-free survival proportion was 66.05% and 58.40% at 1 and 3 years, respectively. Technical failure (OR, 5.61; 95% CI, 1.57-20.04; p = 0.008), and runoff grade 0 (OR, 3.28; 95% CI, 1.09-9.85; p = 0.034) were independent risk factors for vascular events. The total limb salvage proportion at 1 and 3 years was 95.84% and 92.53%, respectively. Technical failure (OR, 8.54; 95% CI, 1.71-40.73; p = 0.02) was identified as an independent risk factor for above ankle amputation. CONCLUSIONS No significant difference in prognosis was found between the atherectomy group and the nonatherectomy group during a midterm follow-up. The technical success of ER was crucial for TAO prognosis.

Abstract
BACKGROUND The use of atherectomy during peripheral endovascular interventions (PVI) has increased dramatically, but data regarding its safety and effectiveness are lacking. Aims: This study sought to determine the long-term safety of atherectomy in contemporary practice. Methods: Medicare fee-for-service beneficiaries who underwent femoropopliteal artery PVI from 2015-2018 were identified in a 100% sample of inpatient, outpatient, and carrier file data using procedural claims codes. The primary exposure was the use of atherectomy. Inverse probability of treatment weighting was used to adjust for measured differences in patient populations. Kaplan-Meier methods and multivariable Cox proportional hazards regression were used to compare outcomes. Results: Among 168,553 patients who underwent PVI, 59,142 (35.1%) underwent atherectomy. The mean patient age was 77.0±7.6 years, 44.9% were female, 81.9% were white, and 46.7% had chronic limb-threatening ischaemia. Over a median follow-up time of 993 days (interquartile range 319-1,377 days), atherectomy use was associated with no difference in the risk of either the composite endpoint of death and amputation (adjusted hazard ratio [aHR] 0.99, 95% confidence interval [CI]: 0.97-1.01; p=0.19) or of major adverse limb events (aHR 1.02, 95% CI: 0.99-1.05; p=0.26). Patients who underwent atherectomy had a modest reduction in the risk of subsequently undergoing amputation or surgical revascularisation (aHR 0.92, 95% CI: 0.90-0.94; p<0.01) but an increase in the risk of undergoing a subsequent PVI (aHR 1.19, 95% CI: 1.16-1.21; p<0.01). CONCLUSIONS The use of atherectomy during femoropopliteal artery PVI was not associated with an increase in the risk of long-term adverse safety outcomes among patients with peripheral artery disease.

Percutaneous mechanical thrombectomy using the Rotarex ®S device for the treatment of acute lower limb artery embolism: A retrospective single-center, single-arm study. Front Surg 2023; 9:1017045. [PMID: 36684256 PMCID: PMC9859659 DOI: 10.3389/fsurg.2022.1017045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Accepted: 12/06/2022] [Indexed: 01/09/2023] Open
Abstract
Objective Acute limb embolism (ALE) is a challenging, highly morbid, and frequently fatal vascular emergency. Percutaneous mechanical thrombectomy (PMT) devices are an alternative treatment to restore perfusion by removing emboli in the limb arterial system. We evaluated the outcomes of treatment of ALE patients using PMT devices in our center. Methods A retrospective review of ALE patients treated with Rotarex S (Straub Medical) at a single institution from 2018 to 2022 was performed. The primary outcome was technical success, defined as complete recanalization of the occluded segment with satisfactory outflow and good capillary filling of the distal parts of the foot without any major or obstructing residual emboli or thrombi either in the treated segment or in the outflow tract without the need for additional catheter-directed thrombolysis (CDT) or conversion to open surgery. Embolized segments treated, treatment outcomes, and perioperative complications were reviewed. Results A total of 17 ALE patients (29% men, 71% women; mean age, 73 years) underwent PMT procedures. The femoral arteries and popliteal arteries are the most commonly treated vessels, with both present in 59% of the patients. The technical success rate was 100%, but the majority of cases (82%) had concurrent percutaneous transluminal angioplasty or stent grafting, and two patients were treated with urokinase during the operation. There was one thrombotic recurrence that required amputation. There were no 30-day deaths. Complications included extravasation after PMT (two), intraoperative embolization of the outflow tract (one), access site hematoma (one), target artery thrombosis (one), and acute kidney injury (one). There were no severe bleeding complications. Conclusions The Rotarex S device has a satisfactory success rate, although complementary use of various adjunctive techniques is frequently required. It seems to be a moderately effective tool for treating ALE to avoid CDT or open surgery. The device appears safe, with low risks of amputation and mortality rates, but special attention should be given to the potential for extravasation and distal embolism.

Abstract
BACKGROUND This retrospective multicenter study aimed to compare the midterm results of the Rotarex rotational thrombectomy device combined with drug-coated balloon (DCB) and DCB-alone for the treatment of subacute femoropopliteal artery thrombotic occlusion. METHODS All patients (74, aged 70.1 ± 9.3 years) were nonrandomized and divided into 2 groups based on treatment strategy between 2018 and 2020. Intraoperative technical success (defined as <30% residual stenosis), dissection types and bailout-stenting rates were assessed. Ankle-brachial index (ABI), primary patency (PP, restenosis <50%) and freedom from clinically driven target lesion reintervention (CD-TLR) were documented at follow-up. RESULTS Among them, 35 patients were treated with the Rotarex catheter combined with DCB while 39 patients underwent DCB-alone. The-overall technical success rate was 100%. Patients in the Rotarex + DCB group showed lower rate of bailout stenting than those in the DCB alone group (22.9% vs. 59.0%; P = 0.01). ABI at discharge was significantly higher in both groups. Mean follow-up time was 18.5 ± 3.4 months; 62 patients completed Doppler ultrasound investigation while 12 patients were censored. According to Kaplan-Meier analysis, the estimated PP was 82.0 ± 6.7% in the Rotarex + DCB group, whereas a significantly lower rate in the DCB alone group (60.9 ± 8.3%, P = 0.04). In addition, the freedom from CD-TLR rate was 82.9 ± 6.4% in the Rotarex + DCB group and 61.5 ± 7.8% in the DCB-alone group (P = 0.04). CONCLUSIONS These initial data indicate that the Rotarex thrombectomy device combined with DCB is an effective choice for the treatment of subacute femoropopliteal artery thrombotic occlusion compared to DCB-alone. The combined procedure had superior midterm results.

Abstract
Background To evaluate the outcomes of percutaneous mechanical thrombectomy (PMT) with Rotarex catheter in patients with acute lower limb ischemia (ALI) caused by aorto-iliac occlusion. Materials and Methods Data of patients with ALI caused by aorto-iliac occlusion in our institutions from January 2010 and April 2020 were reviewed. The primary end point was limb salvage rate. The secondary end points included technical success rate, survival rate, complications after the operation and during the follow-up. Results A total of 85 patients with ALI was diagnosed with aorto-iliac occlusion. Thirty-eight patients were treated by PMT with Rotarex catheter and enrolled in present study. Twenty-four were male (63.2%), and 14 were female (36.8%). The mean age was 66 years (range 28–83). All 38 patients were treated with PMT, with additional catheter directed thrombolysis (2/38, 5.3%), balloon angioplasty (8/38, 21.1%) and stent deployment (7/38, 18.4%). The mean procedure time was 123 ± 31 min. Seven patients (18.4%) underwent continuous renal replacement therapy. Two patients received major amputations (above the knee) and 2 patients died for renal insufficiency and heart failure during the hospital stay. Thirty-day survival rate was 94.7% and limb salvage was 94.4%. The mean follow-up time was 14.0 months (8–22 months). There was no major amputation and target artery occlusion occurred during the follow-up period. Conclusion PMT with Rotarex catheter could be new option for acute aorto-iliac occlusion, leading to safe and effective results.

Abstract
OBJECTIVES To evaluate the efficacy and safety of the Rotarex mechanical thrombectomy device in treating acute lower extremity arterial ischemia and to explore the appropriate indication of Rotarex device. METHODS A retrospective analysis was performed in 186 patients with acute lower extremity arterial ischemia treated with Rotarex mechanical thrombectomy device from April 2015 to March 2020 in three vascular surgery centers of Tianjin. According to the comprehensive judgment of the etiology, onset time, imaging of ultrasonography (US) and angiography, as well as findings during treatment, the patients were divided into the embolization group (69 cases), thrombosis group (primary artery stenosis with thrombosis, 86 cases), and restenosis group (stent restenosis with thrombosis, 31 cases). The primary study outcomes included the success rate of Rotarex mechanical thrombectomy device alone, percutaneous transluminal angioplasty (PTA), stent, catheter-directed thrombolysis (CDT) auxiliary rate, target vessel patency rate, and freedom from clinically-driven target lesion revascularization rate (f-CD-TLR). The secondary study outcomes included intraoperative distal arterial embolization, postoperative 30-day bleeding, deterioration of renal function, amputation, and mortality. RESULTS The success rate of Rotarex mechanical thrombectomy device alone in the embolization group (44.93%) was significantly higher than that in the thrombosis group (13.95%) and restenosis group (0%) (P < 0.01). The PTA auxiliary rate in the embolization group (26.09%) was significantly lower than that in the thrombosis group (72.09%) and restenosis group (100%, P < 0.01). The stent implantation rates in the embolization group and restenosis group (11.60% and 33.30%, respectively) were significantly lower than that in the thrombosis group (72.09%, P < 0.01). There were no significant differences in the CDT auxiliary rate, distal arterial embolization, hemorrhage, renal function deterioration, amputation rate, and mortality among the three groups (P > 0.05). The primary patency at 3 months, 6 months, and 12 months postoperatively was 98.6%, 98.6%, and 84.3% in the embolization group, 96.4%, 89.5%, and 74.9% in the thrombosis group and 93.2%, 84.7%, and 67.5% in the restenosis group respectively (P < 0.01). The f-CD-TLR at 12 months postoperatively was 88.9% in the embolization group, which was higher than 77.8% in the thrombosis group and 67.5% in the restenosis group (P < 0.01). CONCLUSIONS Rotarex mechanical thrombectomy device is a minimally invasive, safe, and effective treatment option for acute lower extremity arterial ischemia, particularly acute arterial embolization. For acute thrombosis secondary to primary artery stenosis and in-stent restenosis, Rotarex device can effectively reduce the thrombus burden and create favorable conditions for other concurrent interventions.

Ann Vasc Surg 2021; 80:213-222. [PMID: 34748945 DOI: 10.1016/j.avsg.2021.08.058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 08/24/2021] [Accepted: 08/27/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Currently, there is little information on the optimal treatment for patients with femoropopliteal total in-stent occlusion.The aim of this study was to evaluate the benefit of drug-coated balloon(DCB) angioplasty after RotarexⓇS rotational atherectomy plus thrombectomy for femoropopliteal total in-stent occlusion at 12 months. METHODS From June 2016 to April 2019, 36 patients (21 male, mean age 71.1 ± 8.2 years) with femoropopliteal total in-stent occlusion were treated using Rotarex S rotational atherectomy plus thrombectomy in combination with DCB angioplasty and 29 (18 male, meanage68.8 ± 7.2 years) underwent DCB angioplasty alone. Primary patency and freedom from target lesion revascularization (TLR) rates during12 months of follow-up were retrospectively compared between the 2 groups. RESULTS Procedural success was achieved in all patients. There were no procedure-related adverse events. The mean lesion length was 26.1 ± 6.5 cm in the combination therapy group and 25.5 ± 6.1 cm in the DCB only group (P = 0.703). The 6-month and 12-month primary patency rates were significantly higher in the combination therapy group (94.4% [standard error, 0.038] and 77.8% [0.069], respectively) than in the DCB only group (72.4% [0.083] and 48.3% [0.093]; P = 0.010). The freedom from TLR rate at 12 months was 86.1% (standard error, 0.060) in the combination therapy group and 62.1% (0.096) in the DCB only group (P = 0.016). Three patients (combination therapy, n = 2; DCB only, n = 1) developed distal embolization and were treated successfully by additional 6-F guiding catheter aspiration. No deaths or amputations occurred in either group during 12 months of follow-up. CONCLUSIONS Rotarex S rotational atherectomy plus thrombectomyin combination with DCB was safe and effective in patients with femoropopliteal total in-stent occlusion during12 months of follow-up.

Abstract
Background: Studies investigating debulking devices with drug-coated balloons (DCBs) in the treatment of femoropopliteal (FP) artery in-stent restenosis (ISR) are limited. We aimed to evaluate the safety and midterm outcome of percutaneous mechanical atherectomy plus thrombectomy (MATH) using the Rotarex®S (Straub Medical, Wangs, Switzerland) catheter followed by a DCB in the treatment of FP-ISR. Methods: This study was a single-center single-arm trial. Patients with symptomatic (Rutherford category 2–5) de novo restenosis lesions of FP-ISR were treated with MATH and subsequent DCB. From June 2016 to May 2018, 59 patients with FP-ISR were enrolled. The primary endpoint was target lesion revascularization (TLR) and changes in the Rutherford category of the target limb at 12 months. Secondary endpoints included primary and secondary patency at 12 months, technical success rate, major adverse events, and ankle-brachial index (ABI). Risk factors for TLR were analyzed using Cox proportional hazard model. Results: The average follow-up time was 33 ± 8 months. The rate of technical success was 88.1% (52/59). Nine patients received bailout stenting. The rate of freedom from TLR was 84.7% (50/59) at 1 year, the Rutherford category changed at 12 months were significantly improved from baseline (p < 0.01). The primary patency rates and the secondary patency at the 12-month follow-ups were 82.5 and 92.5%, respectively. The ABI changed at 12 months were significantly improved from baseline (p < 0.01). Global limb anatomic staging system (GLASS) classification III [hazard ratio (HR) 18.44, 95% CI (1.57–215.99), p = 0.020] and postoperative Rutherford classification ≥4 [HR 8.28, 95% CI (1.85–37.06), p = 0.006] were identified as independent predictors of TLR. Conclusion: Our preliminary data suggested that MATH using a Rotarex®S catheter combined with DCB angioplasty is a safe, minimally invasive, and effective treatment for FP-ISR with favorable, immediate, and midterm outcomes.

Abstract
Background To evaluate the effect of stent compression on in-stent restenosis (ISR) and clinical outcomes in patients with iliac vein compression syndrome (IVCS) after iliac vein stenting. Methods Fifty patients with IVCS treated with iliac vein stenting (Smart Control, Cordis, USA) between March 2017 and October 2018 were consecutively enrolled in this study. Computed tomography venography (CTV) was performed to assess stent compression and ISR. Based on the degree of stent compression, patients were allocated to a significant stent compression (SSC) group and an insignificant stent compression (ISC) group. The incidence of ISR was analyzed between the SSC and ISC groups. Patients' venous clinical severity scores (VCSSs) and responses to the chronic venous insufficiency questionnaire (CIVIQ) one year after stenting were compared between the two groups to evaluate the clinical improvement of venous insufficiency. Results In total, 34% of patients had SSC. There were significant differences in the incidence of ISR (52.9% vs. 21.2%, P=0.023), and in each group, there was one case of stent occlusion (5.88% vs. 3.03%, P=0.999). Patients in the SSC group had a higher VCSS score (8.41±5.92 vs. 3.15±2.87, P=0.04) and a lower CIVIQ score (83.35±8.86 vs. 92.21±4.32, P=0.001). Conclusions SSC has a significant effect on the incidence of ISR and the clinical outcomes of venous insufficiency. Thus, a dedicated iliac venous stent with sufficient radial resistive force, crush resistance, and outward radial force is needed to prevent the occurrence of stent compression.

Abstract
Background Open surgery is the gold standard for the treatment of aortoiliac occlusive disease (AIOD). Endovascular therapy has emerged as an attractive alternative for AIOD due to its minimal invasiveness. The aims of the present study were to investigate the long-term patency of endovascular treatment and to compare the outcomes of Transatlantic Inter-Society Consensus II (TASC II) A/B and C/D lesions. Methods Patients with AIOD (n=156) were enrolled in this retrospective cohort study. Patency rates were assessed at 12, 36, and 60 months after the procedure. Parameters for comparisons between TASC II A/B and C/D lesions included primary patency, secondary patency, freedom from target lesion revascularization (TLR), the technical success rate, the rate of complications, and risk factors for in-stent restenosis. Results For all patients, the technical success rate was 98.7%, the complication rate was 4.5%, and the mean follow-up period was 35.7 months. At 12, 36, and 60 months after the procedure, the primary patency rates were 96.5%, 88.3%, and 80.4%, respectively. The secondary patency rates were 99%, 96.4%, and 88%, respectively. The rates of freedom from TLR were 97.5%, 91.6%, and 89.6%. No significant differences were observed between A/B and C/D lesions in terms of primary patency (P=0.443), secondary patency (P=0.393), or freedom from TLR (P=0.481). Conclusions Endovascular reconstruction is effective and safe for AIOD, and should be the first-line treatment option for patients with TASC II A-D aortoiliac lesions.

Abstract
Objectives The objective of this study was to evaluate the effectiveness of percutaneous mechanical thrombectomy as the initial thrombus removal method in the treatment of acute lower extremity ischemia. Methods The patients with acute lower limb ischemia who underwent percutaneous mechanical thrombectomy between August 2016 and February 2018 were retrospectively reviewed. The patients were diagnosed by clinical examination and computed tomography angiography. The percutaneous mechanical thrombectomy was performed as the initial thrombus removal method, followed by anticoagulation therapy. The patients were followed up by clinical examination, imaging, and ankle brachial index (ABI) examination. Results Thirty-two patients (21 males, 11 females; average age of 68.53 ± 8.05; three cases of grade III, 29 cases of grade IIB) were reviewed. Recanalization of the thromboembolic occlusions were achieved in all patients. ABI significantly ( p < 0.01) increased postoperatively (preoperative ABI: 0.51 ± 0.13; postoperative ABI: 0.85 ± 0.65, ABI at three months postoperatively: 0.84 ± 0.66). Eleven patients underwent balloon dilation and three patients had stent placement. Complete thrombus removal was achieved in all patients. The primary patency at 3 months, 6 months, and 12 months postoperatively was 90%, 85%, and 56%, respectively. The secondary patency at 3 months, 6 months, and 12 months postoperatively was 93%, 87%, and 65%, respectively. Conclusions The immediate result appeared to be effective to use percutaneous mechanical thrombectomy as the first thrombus removal method in the treatment of acute thromboembolic occlusions in the lower extremity, while the midterm result needs to be further improved.

Front Cardiovasc Med 2020; 7:557420.

Abstract
Acute and subacute ischemia of lower limbs is associated with high risk of amputation and potential severe life-threatening complications. Despite a lack of clear therapeutic recommendations, surgical treatments such as thrombectomy or bypass and/or catheter-directed thrombolysis (CDT) have been first-line procedures in both acute and subacute limb ischemia, but each therapy may lead to significant morbidity and mortality. Such situations demand fast restoration of appropriate flow to preclude limb loss and other complications. Percutaneous mechanical atherectomy plus thrombectomy (MATH) represents a minimally invasive approach for quickly recanalizing thrombus-containing lesions whatever the age of thrombus. Indeed, many chronic patients can present with critical limb ischemia, with thrombus-containing occlusive lesions triggered by underlying atherosclerotic disease. MATH offers various advantages over surgery and CDT, with lower invasiveness, faster recanalization, and the possibility to immediately treat the underlying lesions, with a lower rate of bleeding complications and no need for intensive care unit stay. Currently, several mechanical thrombectomy devices are offered as an alternative therapy and can be divided into pure rotational MATH systems and rheolytic thrombectomy devices. The only pure rotational MATH device currently available on the market is the Rotarex S device. We aimed to review contemporary clinical data regarding the safety, efficacy, and outcomes of MATH therapy using Rotarex S catheter in acute and subacute thrombus-containing arterial lesions of lower limbs. Future perspectives of Rotarex S MATH treatment and cost-effectiveness of its routine use will be also discussed.
