    1. Assessment of Vascular Patency and Inflammation with Intravascular Optical Coherence Tomography in Patients with Superficial Femoral Artery Disease Treated with Zilver PTX Stents

      Assessment of Vascular Patency and Inflammation with Intravascular Optical Coherence Tomography in Patients with Superficial Femoral Artery Disease Treated with Zilver PTX Stents

      Purpose Zilver PTX nitinol self-expanding drug-eluting stent with paclitaxel coating is effective for treatment of superficial femoral artery (SFA) disease. However, as with any stent, it induces a measure of vascular inflammatory response. The current clinical trial (NCT02734836) aimed to assess vascular patency, remodeling, and inflammatory markers with intravascular optical coherence tomography (OCT) in patients with SFA disease treated with Zilver PTX stents. Methods Serial OCT examinations were performed in 13 patients at baseline and 12-month follow-up. Variables evaluated included neointimal area, luminal narrowing, thrombus area, stent expansion as well as measures of inflammation including, peri-strut low-intensity area (PLIA), macrophage ...

    2. Impact of Ticagrelor and Aspirin versus Clopidogrel and Aspirin in Symptomatic Patients with Peripheral Arterial Disease: Thrombus Burden Assessed by Optical Coherence Tomography

      Impact of Ticagrelor and Aspirin versus Clopidogrel and Aspirin in Symptomatic Patients with Peripheral Arterial Disease: Thrombus Burden Assessed by Optical Coherence Tomography

      Purpose To compare OCT identified white thrombus decline, neointimal hyperplasia and clinical outcomes of patients treated with ticagrelor plus aspirin with those patients treated with clopidogrel plus aspirin after peripheral interventions. Background Ticagrelor is a potent platelet inhibitor. In patients with coronary artery disease, ticagrelor and aspirin demonstrated reduced rates of stent thrombosis, compared to aspirin and clopidogrel. The clinical importance of potent antiplatelet inhibition after peripheral endovascular interventions is unknown. Methods We enrolled 18 patients with superficial femoral artery disease and the presence of OCT-detected clot post-stent placement. Patients were randomized to 75 mg clopidogrel once daily for 1 ...

    3. Optical coherence tomography to guide below-the-knee endovascular interventions

      Optical coherence tomography to guide below-the-knee endovascular interventions

      Peripheral arterial disease remains a common cause of leg amputations causing significant morbidity and mortality. Data regarding below-the-knee endovascular interventions is scarce while long-term patency rates via different endovascular revascularization modalities remain limited. OCT offers excellent three dimension endothelial visualization; however its value to guide peripheral interventions has not been studied. We describe the use of OCT to guide endovascular below-the-knee interventions in order to achieve excellent OCT results.

    5. Use of Optical Coherence Tomography During Superficial Femoral Artery Interventions

      Use of Optical Coherence Tomography During Superficial Femoral Artery Interventions

      Superficial femoral artery (SFA) disease accounts for approximately 40% of the symptomatic peripheral arterial disease and remains a common cause of critical limb ischemia and lower-extremity amputation. Optical coherence tomography (OCT) has been extensively studied in the coronary circulation; however, its use in the peripheral arterial circulation is scarce. We present two cases of OCT use as an ancillary imaging tool during SFA endovascular interventions

    6. Ocelot catheter for the recanalization of lower extremity arterial chronic total occlusion: Mini review

      Ocelot catheter for the recanalization of lower extremity arterial chronic total occlusion: Mini review

      Peripheral arterial disease (PAD) is a growing clinical condition affecting more than 10 million patients in the United States and it is responsible for more than 120,000 amputations annually. The presence of chronic total occlusions (CTO) increases the complexity of endovascular procedures and open surgery may often be the preferred approach. Despite the optimization of the CTO devices and technique, percutaneous CTO revascularization remains a challenging procedure even for experienced operators with important complication rates. The Ocelot TM system is a novel CTO device to use real-time optical coherence tomography (OCT) imaging guidance for the recanalization of peripheral CTOs ...
