Abstract
PURPOSE Carotid stenting has been demonstrated to effectively reduce the risk of stroke in appropriately selected patients. However, application of carotid artery stenting remains limited in the setting of heavily calcified disease. CASE REPORT We present here 3 patients, who were treated with intravascular lithotripsy of the internal and common carotid arteries. All 3 patients recovered uneventfully and have demonstrated excellent stent expansion on surveillance imaging. CONCLUSION Intravascular lithotripsy is an effective adjunct for enabling stent expansion in heavily calcified lesions and can be employed for the treatment of high-risk carotid lesions that would otherwise be poor endovascular candidates. CLINICAL IMPACT Carotid artery stenting via transfemoral or transcarotid application remains limited by heavily calcified disease. We present here the off-label use of intravascular lithotripsy as an effective adjunct for enabling stent expansion in heavily calcified lesions. There is potential for intravascular lithotripsy to expand the use of carotid stenting.

Abstract
Patients with chronic limb-threatening ischemia, the terminal stage of peripheral artery disease, are frequently afflicted by below-the-knee disease. Although all patients should receive guideline-directed medical therapy, restoration of inline flow is oftentimes necessary to avoid limb loss. Proper patient selection and proficiency in endovascular techniques for below-the-knee revascularization are intended to prevent major amputation and promote wound healing. This review, a consensus among an international panel of experienced operators, provides guidance on these challenges from an endovascular perspective and offers techniques to navigate this complex disease process.

Sex-specific analysis of intravascular lithotripsy for peripheral artery disease from the Disrupt PAD III observational study. J Vasc Surg 2024; 79:358-365. [PMID: 37925039 DOI: 10.1016/j.jvs.2023.10.058] [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: 06/12/2023] [Revised: 10/06/2023] [Accepted: 10/28/2023] [Indexed: 11/06/2023]
Abstract
OBJECTIVE Endovascular therapy of lower extremity peripheral artery disease (PAD) is associated with higher complication rates and worse outcomes in women vs men. Although intravascular lithotripsy (IVL) has shown similarly favorable outcomes in men and women in calcified coronary arteries, there is no published safety and effectiveness data of peripheral IVL differentiated by sex. This study aims to evaluate sex-specific acute procedural safety and effectiveness following IVL treatment of calcified PAD. METHODS We performed a secondary analysis of the multicenter Disrupt PAD III Observational Study, which assessed short-term procedural outcomes of patients undergoing treatment of symptomatic calcified lower extremity PAD with the Shockwave peripheral IVL system. Adjudicated acute safety and efficacy outcomes were compared by sex using univariate analysis performed with the χ2 test or Fisher exact test, as appropriate. RESULTS A total of 1262 patients (29.9% women) were included, with >85% having moderate to severe lesion calcification. Women were older (74 vs 71 years; P < .001), had lower ankle-brachial index (0.7 vs 0.8; P = .003), smaller reference vessel size (5.3 vs 5.6 mm; P = .009), and more severe stenosis at baseline vs men (82.3% vs 79.8%; P = .012). Rates of diabetes, renal insufficiency, chronic limb-threatening ischemia, lesion length, and atherectomy use were similar in both groups. Residual stenosis after IVL alone was significantly reduced in both groups. Final residual stenosis was 21.9% in women and 24.7% in men (P = .001). Serious angiographic complications were infrequent and similar in both groups (1.4% vs 0.6%; P = .21), with no abrupt vessel closure, distal embolization, or thrombotic events during any procedure. CONCLUSIONS The use of IVL to treat calcified PAD in this observational registry demonstrated favorable acute safety and effectiveness in both women and men.

Periprocedural Outcomes of Rotational Atherectomy-Assisted Balloon Angioplasty in Isolated Atherosclerotic Popliteal Artery Lesions: The ISO-POP Trial. J Clin Med 2023; 12:jcm12082797. [PMID: 37109133 PMCID: PMC10144177 DOI: 10.3390/jcm12082797] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Revised: 03/25/2023] [Accepted: 03/27/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND Treatment of calcified popliteal artery lesions represents an ongoing challenge for vascular specialists. Biomechanical forces of external compression, torsion and elongation that occur with locomotion in the popliteal segment can lead to stent fractures and occlusions. The aim of our study was to assess the procedural success rate of atherectomy in combination with balloon angioplasty for isolated calcified popliteal artery lesions. METHODS Between January 2020 and December 2022, 62 patients with isolated atherosclerotic lesions of the popliteal artery underwent endovascular treatment by use of rotational atherectomy (Phoenix, Philips USA, (subgroup A) or Jetstream, Boston USA, (subgroup B), atherectomy systems) and additional balloon angioplasty in two vascular centers. The primary outcome measures were: 1. periprocedural clinical and technical success (<30% residual stenosis and no need for bailout stenting due to flow-limiting dissection) and 2. postprocedural increase in the ankle brachial index of more than 0.1. RESULTS The overall rate of bailout stenting was 4.8%, whereas the procedural success rate was 98.4%. The rate of procedural complications included 3.7% and 5.7% peripheral embolizations in the subgroups A and B, respectively, and no vessel perforations were noted. All embolizations were successfully treated by catheter aspiration or capture in the pre-treatment placed filter system. In addition, 1 (3.7%) pseudoaneurysm in the groin was reported in subgroup A and treated by surgical means. Median ABI of the affected limbs improved from 0.55 (0.2) to 0.70 (0.2) in subgroup A and from 0.50 (0.2) to 0.95 (0.1) in subgroup B (DABI of 0.15 versus 0.45, p < 0.001). CONCLUSIONS The combination of rotational atherectomy and balloon angioplasty in the popliteal artery showed reproducible outcomes in 2 centers, with low incidence of complications and low rates of bail-out stenting. These findings may contribute to more liberal use of such devices especially in segments with high risk for stent factures and occlusions.

Abstract
Peripheral artery disease (PAD) shows increasing need for revascularization therapy. Interventional success in calcified lesions is limited. Here, intravascular lithotripsy (IVL), modifying intimal and medial calcium, is a promising treatment approach. A single-center, prospective all-comers registry for patients undergoing peripheral IVL was established to examine treatment success in PAD with severe vessel calcification. Periprocedural safety events as well as short-term and intermediate follow-up clinical data were evaluated. Between December 2018 and January 2021 all consecutive patients receiving peripheral lithotripsy at our center were analyzed. Clinical and angiographic data were evaluated. Angiographic images were analyzed using a semiautomatic software for quantitative vessel analysis. Eighty-five lesions in 61 limbs were treated with IVL in 51 patients presenting with Rutherford classes 2 to 5. Most lesions (68%) were localized in the superficial femoral artery. Mean calcified lesion length was 102.5 mm (10-390 mm), with a median peripheral arterial calcium score of 3, indicating a highly calcified status. In 58% of the patients, IVL was used as a stand-alone therapy. IVL resulted in a mean acute luminal gain of 2.6 ± 0.9 mm, resulting in stenosis reduction by 42.1 ± 15%. Mean ankle brachial index (ABI) improved significantly from 0.6 to 0.8 ( p < 0.0001) on day 1 after the intervention and remained stable at 6 months. This large real-world data of peripheral IVL reports compelling safety in a complex patient cohort. For the first time, clinical follow-up data demonstrated a sustained significant improvement in ABI after 6 months.

Abstract
BACKGROUND Vessel preparation for endovascular treatment (EVT) is important but because the contributory factors for favorable outcomes are not yet known, we conducted the present study to elucidate the factors associated with sufficient vessel preparation for severely calcified femoropopliteal (FP) lesions.Methods and Results: This was a single-center retrospective observational study of 97 patients (mean age, 75±8 years, 76% male) with 106 de novo severely calcified FP lesions who underwent EVT under intravascular ultrasound (IVUS) evaluation. The lesion definition was 360° of superficial calcification on IVUS. The primary outcome measure was sufficient vessel preparation, which was defined as successful cracking of severely calcified lesions evaluated by IVUS after predilation. The mean lesion length was 200±103 mm, and chronic total occlusion was present in 38% of patients. According to the greater difference between the preballoon size and the lumen diameter of the severely calcified lesion, the frequency of sufficient vessel preparation increased (odds ratio, 4.68; 95% confidence interval, 2.09-10.49; P<0.01). Balloon type (noncompliant, P=0.80; scoring: P=0.25) and pressure (P=0.27) were non-contributory. CONCLUSIONS The difference between the lumen diameter at the severely calcified FP lesion site and the preballoon dilatation diameter was the sole factor contributing to sufficient vessel preparation.

Abstract
Purpose Arterial stiffness and steno-occlusion of the lower-extremity can result from many vascular lesions, including acute thromboembolisms, soft plaques, calcified plaques, or inflammatory disease. Ultrasound (US) elastography measures the tissue deformation response to compression and displays tissue stiffness. This study aimed to evaluate the characteristics of arterial lesions in the lower extremities using US elastography. Materials and Methods We retrospectively analyzed the data of 20 patients who visited our institute for arterial disease treatment between May 2016 and November 2017. An US examination with B-mode and strain elastography (SE) was performed of four different lesion types at 45 sites: acute and subacute thromboembolisms, soft plaques, calcified plaques, and thromboangiitis obliterans lesions (TAOs). During SE, stress was externally applied by the operator using the transducer. Strain ratio (SR) was calculated as the fraction of the average strain in the reference area divided by the average strain in the lesion. The SR was compared among different lesion types, with the accompanying vein as the reference region of interest. Results The strain was highest in the soft plaques (0.63%±0.23%), followed by the TAOs (0.45%±0.11%), calcified plaques (0.44%±0.13%), and acute thromboembolisms (0.34%±0.23%), which were statistically significant (P=0.026). However, the mean SR was highest for the calcified plaques (2.33%±0.80%), followed by the TAOs (1.63%±0.40%), acute thromboembolisms (1.60%±0.48%), and soft plaques (1.51±0.39), and which were statistically significant (P=0.013). Conclusion Despite several limitations, vascular elastography may be useful for differentiating between lesion types in peripheral arterial disease.

Abstract
Atherectomy has become a promising treatment option for peripheral artery disease caused by diabetes mellitus or end-stage renal disease. Atherectomy refers to the removal of atheromatous tissue by mechanical method, resulting in an enlarged lumen of the treated blood vessel. Based on this method, the term is limited to the percutaneous minimally invasive approach, and there are currently two types of atherectomy devices available in Korea. The increased prevalence of atherectomy has led to the concept of "vascular preparation" and a new treatment concept of "leave nothing behind." Various studies have proven the safety and effectiveness of atherectomy; however, there are some limitations. We need to remain focused on patient selection and subsequent large-scale research.

Abstract
OBJECTIVES To compare the safety and efficiency of atherectomy plus drug-coated balloon with drug-coated balloon only for the treatment of femoropopliteal artery lesions. METHODS This systematic review and meta-analysis was performed and reported following the requirement of the PRISMA. EMBASE, MEDLINE, and Cochrane library were queried from January 2000 to June 2020 to identify eligible literature. The modified Downs and Black checklist was used to assess the quality of included studies. Outcome measures included bail-out stenting, distal embolization, perforation, hematoma, primary patency at 12 months, target lesion revascularization at 12 months, leg amputation at 12 months, and mortality at 12 months. We used DerSimonian and Laird random-effects model to pool the dichotomous data on risk ratio (RR) with 95% confidence intervals (CIs) from each study to obtain an overall estimate for major outcomes. Subgroup analysis and sensitivity analyses were conducted. RESULTS Six studies (two randomized controlled trials and four retrospective cohort studies) with 470 patients were included. Atherectomy plus drug-coated balloon group was associated with lower rates of bail-out stenting (RR: 0.49, 95%CI: 0.34-0.71, P < 0.001). There was no significant difference between two groups in terms of distal embolization (RR: 2.06, 95%CI: 0.51-8.38, P = 0.31), perforation (RR: 2.04, 95%CI: 0.43-9.71, P = 0.37), hematoma (RR: 1.75, 95%CI: 0.43-7.09, P = 0.43), primary patency at 12 months (1.09, 95%CI: 0.98-1.21, P = 0.12), target lesion revascularization at 12 months (RR: 0.68, 95%CI: 0.41-1.14, P = 0.15), leg amputations at 12 months (RR: 0.54, 95%CI: 0.13-2.23, P = 0.39), mortality at 12 months (RR: 2.18, 95%CI: 0.71-6.64, P = 0.17). Sensitivity analysis had no effect on our findings. CONCLUSIONS The combination of atherectomy and drug-coated balloon was safe and effective in the treatment of femoropopliteal artery lesions, with lower incidence of bail-out stenting compared with drug-coated balloon only.

Abstract
Objectives The aim was to report the mid-term outcomes of Jetstream™ rotational atherectomy device in complex femoropopliteal lesions. Methods Between November 2016 and April 2018, 55 patients who were treated with rotational atherectomy and adjunctive balloon angioplasty due to complex femoropopliteal lesions were retrospectively scanned. Results Fifty-five patients who underwent endovascular treatment with rotational atherectomy for chronic total occlusive femoropopliteal lesions were included in the study. Technical success rate was 100%. The mean age was 63 (±10.5) years. The cohort included 25 (45.4%) diabetics and 45 (81.8%) current smokers. The mean length of the lesions was 20.8 ± 11.2 cm. Chronic total occlusive lesions were detected in 35 (63.6%) patients, and mixed-type steno-occlusive lesions were detected in 20 patients (36.4%). Thirty-three (60%) lesions were moderate or severely calcified. Adjunctive balloon angioplasty was performed with plain old balloon angioplasty (POBA) on 31 (56.4%) patients and with drug-coated balloon angioplasty on 24 (43.6%) patients. After adjunctive balloon angioplasty, flow limiting dissection was observed in 20 (36.3%) patients, and 17 (30.9%) patients needed stent implantation. The Kaplan–Meier analysis method estimated that the overall primary patency rates at 12 and 24 months were 81.8% and 70.9%, respectively. Overall, secondary patency rates at 12 and 24 months were 94.5% and 80%. No statistically significant differences of 24-month primary patency and secondary patency rates were found between patients treated with drug-coated balloon angioplasty and POBA as an adjunctive therapy, even though primary patency (83.3% vs. 61.3%, p = .06) and secondary patency (91.7% vs. 71%, p = .56) rates of drug-coated balloon angioplasty were slightly higher than POBA. Patients with claudication had better primary patency (90.5% vs. 58.8%, p = .001) and secondary patency (100% vs. 67.6%, p = .004) rates than patients with critical limb ischemia at 24 months. Significant differences between patients who did and did not stop smoking were found in 24-month primary patency (57% vs. 88%, p = .007) and secondary patency (67% vs. 96%, p = .007). Six patients underwent unplanned amputation. There were eight (14.5%) mortalities during follow-up. Conclusions Rotational atherectomy with adjunctive balloon angioplasty has satisfactory technical success rates and mid-term outcomes. As an adjunctive method, there was no difference between drug-coated balloon angioplasty s and POBAs. Smoking cessation is always the first-step treatment to improve mid-term patency results. Patients with critical limb ischemia have worse patency results compared to the patients with claudication.
