    Abstract Background:  Although uncomplicated Type B aortic dissection (uTBAD) is traditionally treated with optimal medical therapy (OMT) as per guidelines, recent studies, performed primarily in interventional radiology or surgical operating rooms, suggest superiority of thoracic endovascular aortic repair (TEVAR) over OMT due to recent advancements in endovascular technologies. We report a large, single-center, case control study of TEVAR versus OMT in this population, undertaken solely in a cardiac catheterization laboratory (CCL) with a cardiologist and surgeon. We aimed to determine if TEVAR for uTBAD results in better outcomes compared with OMT.
    Methods:  This was a retrospective chart review of all patients with uTBAD during the last 13 years, with 46 cases (TEVAR group) and 56 controls (OMT group).
    Results:  In the TEVAR group, the procedure duration of 2.5 hours resulted in 100% procedural success for stent placement, with 63% undergoing protective left subclavian artery bypass, 0% mortality or stroke, and a lower readmission rate (1 vs. 2%;
    Conclusion:  TEVAR performed solely in the CCL is safe and effective, with lower all-cause mortality than OMT. These data, in collaboration with previous data on TEVAR in different settings, call for consideration of an update of practice guidelines.

    Abstract Background: Atherectomy use in treatment of femoropopliteal disease has significantly increased despite scant evidence of benefit to long-term clinical outcomes.
    Aims: We investigated the clinical benefits of atherectomy over standard treatment for femoropopliteal interventions.
    Methods: Using data from the Society of Vascular Surgery's Vascular Quality Initiative (VQI) registry, we identified patients who underwent isolated femoropopliteal interventions for occlusive disease. We compared 13,423 patients treated with atherectomy with 47,371 receiving standard treatment; both groups were allowed definitive treatment with a drug-coated balloon or stenting. The primary endpoint was major adverse limb events (MALEs), which is a composite of target vessel re-occlusion, ipsilateral major amputation, and target vessel revascularization.
    Results: Mean age was 69 ± 11 years, and patients were followed for a median of 30 months. Overall rates of complications were slightly higher in the atherectomy group than the standard treatment group (6.2% vs. 5.9%, p < 0.0001). In multivariable analysis, after adjusting for demographic and clinical covariates, atherectomy use was associated with a 13% reduction in risk of MALEs (adjusted odds ratio [aOR]: 0.87; 95% confidence interval [CI]: 0.77-0.98). Rates of major and minor amputations were significantly lower in the atherectomy group (3.2% vs. 4.6% and 3.3% vs. 4.3%, respectively, both p < 0.001), primarily driven by a significantly decreased risk of major amputations (aOR 0.69; 95% CI: 0.52-0.91). There were no differences in 30-day mortality, primary patency, and target vessel revascularization between the atherectomy and standard treatment groups.
    Conclusions: In adults undergoing femoropopliteal interventions, the use of atherectomy was associated with a reduction in MALEs compared with standard treatment.

    Abstract Objective: Small, older studies have suggested that the use of atherectomy devices has become common in peripheral vascular interventions (PVIs) despite the paucity of strong clinical guidelines. We analyzed the 10-year trends in the use of atherectomy for PVIs across the United States and identified the main predictors of atherectomy use.
    Methods: Using the Vascular Quality Initiative registry, we identified all patients who had undergone endovascular PVIs for occlusive lower extremity arterial disease from 2010 to 2019. Procedures in which an atherectomy device had been used as the primary or secondary device were classified as the atherectomy group. We calculated the frequency of atherectomy use over time and across geographic regions. Using regression modeling, we identified the factors that were independently associated with atherectomy use.
    Results: A total of 205,377 PVIs had been performed for 152,693 unique patients. During the 10-year period, 16.6% of the PVI procedures had used atherectomy, increasing from 8.5% in 2010 to 19.7% in 2019 (P
    Conclusions: Atherectomy use in PVI significantly increased from 2010 to 2019. We found wide regional variability in the use of atherectomy that seemed to be driven more strongly by nonclinical factors.

    Abstract Purpose: To evaluate the effectiveness and safety of atherectomy versus plain balloon angioplasty (POBA) for treatment of critical limb ischemia (CLI) due to tibioperoneal arterial disease (TPAD).
    Materials and methods: Patients enrolled in the Vascular Quality Initiative registry who had CLI (Rutherford Class 4-6) and underwent atherectomy versus POBA alone for isolated TPAD were retrospectively identified. Of eligible patients, a cohort of 2,908 patients was propensity matched 1:1 by clinical and angiographic characteristics. The atherectomy group comprised 1,454 patients with 2,183 arteries treated, and the POBA group comprised 1,454 patients with 2,141 arteries treated. The primary study endpoint was major ipsilateral limb amputation. Secondary endpoints were minor ipsilateral amputations, any ipsilateral amputation, primary patency, target vessel reintervention (TVR), and wound healing at 12 months.
    Results: The median follow-up period was 507 days, the mean patient age was 69 years ± 11.7, and the mean occluded length was 6.9 cm ± 6.5. There was a trend toward higher technical success rates with atherectomy than with POBA (92.9% vs 91.0%, respectively; P = .06). The rates of major adverse events during the procedure were not significantly different. The 12-month major amputation rate was similar in the atherectomy and POBA groups (4.5% vs 4.6%, respectively; P = .92; odds ratio, 0.97; 95% CI, 0.68-1.37). There was no difference in 12-month TVR (17.9% vs 17.8%; P = .97) or primary patency (56.4% vs 54.5%; P = .64) between the atherectomy and POBA groups.
    Conclusions: In a large national registry, treatment of CLI from TPAD using atherectomy versus POBA showed no significant differences in procedural adverse events, major amputations, TVR, or vessel patency at 12 months.

    Abstract Elimination of the embolic potential of existing thrombus, restoration of unobstructed flow, prevention of further thrombosis, and preservation of venous valve function are the ideal goals of therapy for acute deep vein thrombosis (DVT). Meeting these goals will not only prevent pulmonary embolus, but will also minimize long-term sequelae of venous hypertension and development of postthrombotic syndrome (PTS). Treatment strategies aimed at eliminating or reducing risk of PTS should focus on preserving valvular function and eliminating risk of continued venous obstruction after acute DVT. Thrombolytic agents are an attractive form of early therapy because they have the ability to eliminate obstructive thrombus in the deep veins, and should therefore help provide protection against PTS. Perceived benefits of early and rapid recanalization in preserving valve function have been the basis for lytic therapy to treat acute DVT. Data from the National Venous Registry and subsequent reports on the role of catheter-directed thrombolysis for treatment of acute lower-extremity DVT indicate that the technique is safe and effective in select patients. More recently, implementation of percutaneous mechanical devices designed to quickly remove acute thrombus has had a significant impact on time and cost of catheter-directed thrombolysis procedure. Although the long-term benefits of this form of therapy are not yet completely known, the Venous Registry can serve as a guide to the judicious selection of patients who will most benefit from this aggressive form of therapy.

    Abstract The 1- to 2-year primary patency rates associated with self-expanding nitinol stents for the treatment of symptomatic femoropopliteal disease are superior to those for percutaneous transluminal angioplasty (PTA) and the first-generation stainless steel balloon-expandable stents. The advantages of nitinol stents include improved radial strength and flexibility, the ability to recover from being crushed, reduced foreshortening, and (importantly) deployability without balloon dilation of the stent edge (which may decrease the incidence of the edge stenosis, or "candy-wrap" effect, often observed with balloon-expandable stents). The technical success rate associated with primary deployment of nitinol stents is very high, and acute to 6-month patency results are predictably excellent. Prior to the introduction of nitinol stents, the original guidelines (2000) of the multidisciplinary TransAtlantic Inter-Society Consensus (TASC I) recommended only an adjunctive role for femoropopliteal stents following suboptimal PTA. The abbreviated 2007 TASC II report essentially extended this recommendation to nitinol stents. Here, current trials of nitinol stenting in the femoropopliteal segment are discussed, with emphasis on the advantages of primary (and often direct) deployment in selected circumstances dependent on factors including lesion length, lesion location, indication for treatment (critical limb ischemia or claudication, in-stent restenosis, stent-graft restenosis), and the relative appropriateness of other modalities (e.g., covered stents). Technical considerations in primary nitinol stenting are briefly reviewed. Open questions regarding the factors involved in nitinol stent fracture and the possible association of fracture and restenosis are examined in the context of current clinical trials. A new generation of femoropopliteal nitinol stents combining superior durability and flexibility is expected soon. Development and implementation of uniform reporting and surveillance standards is important for optimizing current and future research.

    Abstract Background: Although uncomplicated Type B aortic dissection (uTBAD) is traditionally treated with optimal medical therapy (OMT) as per guidelines, recent studies, performed primarily in interventional radiology or surgical operating rooms, suggest superiority of thoracic endovascular aortic repair (TEVAR) over OMT due to recent advancements in endovascular technologies. We report a large, single-center, case control study of TEVAR versus OMT in this population, undertaken solely in a cardiac catheterization laboratory (CCL) with a cardiologist and surgeon. We aimed to determine if TEVAR for uTBAD results in better outcomes compared with OMT.
    Methods: This was a retrospective chart review of all patients with uTBAD during the last 13 years, with 46 cases (TEVAR group) and 56 controls (OMT group).
    Results: In the TEVAR group, the procedure duration of 2.5 hours resulted in 100% procedural success for stent placement, with 63% undergoing protective left subclavian artery bypass, 0% mortality or stroke, and a lower readmission rate (1 vs. 2%; p  = 0.04 in early TEVAR cases), but a longer length of stay (12.9 vs. 8.5 days: p  = 0.006). The risk of all-cause long-term mortality was markedly reduced in the TEVAR group (RR = 0.38; p  = 0.01), irrespective of early (<14 days) versus late intervention. On follow-up computed tomography imaging, the false lumen stabilized or decreased in 85% of cases, irrespective of intervention timing.
    Conclusion: TEVAR performed solely in the CCL is safe and effective, with lower all-cause mortality than OMT. These data, in collaboration with previous data on TEVAR in different settings, call for consideration of an update of practice guidelines.

    Abstract A transgraft embolization (TGE) technique was performed in a patient to treat a type II endoleak. Using a transfemoral arterial approach, the endograft was punctured using a coronary laser catheter aimed toward the type II endoleak nidus, which was treated with Onyx (Medtronic, Minneapolis, Minnesota). TGE resulted in successful embolization, as demonstrated on 1-year follow-up CT angiography, which showed complete elimination of the type II endoleak and shrinkage of the aneurysmal sac. TGE is an alternative to transarterial embolization, translumbar embolization, and transcaval embolization.

    Abstract In the femoropopliteal arterial segment, balloon angioplasty is a recommended treatment strategy for short lesions. Over the past few years, several reports have emerged on the potential role of self-expanding stents for treating longer, more complex disease segments where the patency following balloon angioplasty is notoriously dismal. This paper will attempt to review the emerging role of nitinol stents for treating patients with chronic lower limb ischemia, secondary to severe femoropopliteal arterial disease.
