“…It was not possible to determine if these findings were statistically significant due to the small number of cases. However, the percutaneous directional atherectomy has been shown to be a minimally invasive and safe interventional therapy that achieves a high patency rate and requires a low use of stents (17,18).…”

Background: The purpose of this study was to determine the efficacy of interventional endovascular treatment (EVT) and the risk factors for postoperative restenosis in patients with Trans-Atlantic Inter-Society Consensus (TASC) II C/D femoropopliteal lesions.Methods: A total of 55 patients who received EVT for TASC Ⅱ C/D femoropopliteal lesions (64 affected limbs) from October 2014 to September 2017 were examined. The mean lesion length was 19.6±5.3 (range, 15.5-26.4 cm). The femoropopliteal lesions were classified as TASC Ⅱ C and TASC Ⅱ D in 39 and 16 cases, respectively. The ankle-brachial index (ABI), primary patency rate, secondary patency rate, and limb salvage rate were monitored in follow-up evaluations for up to 24 months. A Cox regression model was used to evaluate the correlation between each of these factors and the restenosis rate after EVT.Results: Patent TASC Ⅱ C/D femoropopliteal lesions were present in 59 of the 64 limbs. The mean ABI values for the dorsal pedal artery and posterior tibial artery increased 1 month after treatment from a baseline level of 0.35±0.12 to 0.89±0.10 and from 0.43±0.15 to 0.90±0.13, respectively (P<0.01). The mean follow-up time was 19.3 (range, 6-24) months. The cumulative primary patency rates at 1, 3, 6, 12, 18, and 24 months were 98.3%, 91.5%, 84.3%, 61.1%, 53.1%, and 31.1%, respectively. The secondary patency rates at 12 and 24 months were 70.4% and 60.0%, respectively. Factors with a high hazard ratio included male sex, TASC II D, smoking, and diabetes mellitus (DM).Conclusions: EVT had a safe and satisfactory mid-term therapeutic effect on TASC II C/D femoropopliteal lesions. Male sex, TASC II D (compared to TASC II C), smoking, and DM were risk factors for restenosis. EVT has a secondary patency rate comparable to that of open surgery and can be considered a first-line treatment for TASC II C/D femoropopliteal lesions.

“…20 When distal arterial embolization occurs, suction the plaque or dilate the balloon to promote plaque adherence and restore the lumen diameter. Minko et al 21 studied 53 patients with superficial calcification stenosis (total of 59 lesions) treated with the Hawk system and reported that 7 (1.19%) had distal arterial embolization during surgery which were successfully removed by catheter suction. In our study, we used the same method during surgery and successfully removed the embolization caused by plaque shedding.…”

Background: Information regarding the efficacy of the TurboHawk atherectomy for the treatment of in-stent restenosis (ISR) in patients with peripheral artery disease (PAD) of the lower extremity is scarce. This study was performed to investigate the curative efficacy and safety of the TurboHawk system for ISR in PAD patients over 60 years old. Methods: The TurboHawk atherectomy device was used to treat ISR in 28 patients with PAD. The intraoperative, 2-day postoperative, 3-month, and 2-year follow-up data were obtained. Differences in the ankle-brachial index (ABI), Rutherford class and minimum diameter of the femoral-popliteal artery were analysed along with the correlations of the factors associated with patency. Results: Twenty-six patients (92.86%) had successful surgeries. All patients reported alleviation of pain and intermittent claudication after surgery. One patient who had a malignant hepatoma and coronary heart disease received an amputation on the 76th postoperative day and another patient who had atrial fibrillation received a thrombectomy on the 40th postoperative day. TurboHawk atherectomy increased the ABI (from 0.30 to 0.70, P < 0.0001) and minimum diameter (from 0 to 4.93 mm, P < 0.0001) and reduced the Rutherford class (from 4.00 to 2.00, P < 0.0001). During the 3-month follow-up, the median minimum diameter, ABI, and Rutherford class were 4.12, 0.69, and 2.00, respectively. No death happened during the 3-month follow-up. Conclusions: The TurboHawk atherectomy is a safe and effective technique for ISR in PAD patients over 60 years old. and excisional atherectomy. 4,5 However, data on the efficacy and safety of the TurboHawk plaque excision system for ISR in patients with lower extremity PAD is lacking.This study aimed to evaluate the efficacy and safety of TurboHawk atherectomy in ISR. The ischaemic limbs of 28 patients with ISR were treated by TurboHawk atherectomy. The intraoperative, 2-day and 3-month postoperative data were collected and analysed.

Three-Year Results After Directional Atherectomy of Calcified Stenotic Lesions of the Superficial Femoral Artery

Abstract: In this subgroup of patients with POD and calcified stenotic lesions, atherectomy was successfully applied to decrease the plaque burden. Results after 3 years showed a significant decrease of Rutherford score with persistent improvement of ABI and reasonable patency rate.
