This analysis compared the angiographic outcomes of patients treated with orbital atherectomy for calcified common femoral artery (CFA) and superficial femoral artery (SFA) disease. The ideal revascularization strategy for CFA disease is unknown. Endarterectomy has been considered the standard of care for CFA disease for over 50 years. Endovascular intervention is becoming more commonly used to revascularize the CFA given the advances in technology and the less invasive nature of the procedure. Patient demographics, lesion characteristics, and procedure data for all CONFIRM patients with at least one CFA lesion location ( n=147 patients; n=200 lesions) were compared to patients with at least one SFA lesion location ( n=1508 patients; n=2367 lesions)...

BCR-ABL1-negative myeloproliferative neoplasms (MPNs) are clonal stem cell disorders defined by proliferation of one or more myeloid lineages, and carry an increased risk of vascular events and progression to myelofibrosis and leukemia. Portal hypertension (pHTN) occurs in 7-18% of MPN patients via both thrombotic and nonthrombotic mechanisms and portends a poor prognosis. Transjugular intrahepatic portosystemic shunt (TIPS) has been used in the management of MPN-associated pHTN; however, data on long-term outcomes of TIPS in this setting is limited and the optimal management of medically refractory MPN-associated pHTN is not known...

INTRODUCTION: Surgical patients requiring an interruption in dual-antiplatelet therapy (DAPT) within 6 months of cardiac stenting are at risk for thrombotic events. Bridging with short-acting intravenous antiplatelet agents has been proposed to minimize the risk of thrombotic and hemorrhagic complications. METHODS: This was a retrospective analysis of a tirofiban bridging strategy that did not use an initial bolus loading dose. Tirofiban infusions were initiated 24to 48 hours after the last oral antiplatelet dose at a rate of 0...

REVIEW
Andrew M Veitch
Management of patients on anticoagulant or antiplatelet therapy undergoing endoscopy presents a balance of risks between haemorrhage due to the procedure, and thrombosis due to discontinuation of antithrombotic therapy. Haemorrhage is usually controllable endoscopically, but thrombosis could, on occasion, result in myocardial infarction or stroke, with permanent disability or death. For elective procedures, there is adequate time to plan best management of antithrombotic therapy. International guidelines have been published, but recommendations are based on limited evidence and consultation with appropriate medical specialists, and the patient is important...

Percutaneous transluminal coronary angioplasty with coronary stent implantation is a life-saving medical procedure that has become, nowadays, the most frequent performed therapeutic procedure in medicine. Plain balloon angioplasty, bare metal stents, first and second generation drug-eluting stents, bioresorbable and bioabsorbable scaffolds have offered diachronically a great advance against coronary artery disease and have enriched our medical armamentarium. Stented areas constitute vulnerable sites for endothelial damage, endothelial dysfunction, flow turbulence, hemorheologic changes, platelet dysfunction, coagulation changes and fibrinolytic disturbances...

Although Nobori(®), with a bioresorbable polymer and biolimus A9 abluminal coating, has unique characteristics, few data exist regarding endothelialization early after implantation. Fifteen Nobori(®) and 14 control bare-metal stents (S-stent™) were implanted in 12 pigs. Histopathology of stented segments, inflammation, and intimal fibrin content was evaluated on the 2nd and 14th day after implantation. On the 2nd day, endothelial cells were morphologically and immunohistologically confirmed on the surface of both stents, although some inflammatory cells might be involved...

Dacron grafts are frequently used during surgical revascularization procedures. Complications including graft thrombosis and infection are well known; however, aneurysm formation is extremely rare. In this report, we describe dilatation of a Dacron graft detected four years after aortobifemoral bypass procedure in a 50-year-old male patient who was treated with endovascular stent grafting.

BACKGROUND Development of a true coronary aneurysm after percutaneous coronary intervention is a rare event, and a coronary aneurysm resulting in acute myocardial infarction is even rarer. Coronary aneurysm formation after bioresorbable vascular scaffold (BVS) implantation, eventually leading to thrombosis, embolization, and myocardial infarction, has never been reported before in the literature. CASE REPORT A 62-year-old man received an elective BVS for a proximal left anterior descending lesion. Two months later, he suffered from a non-ST-segment myocardial infarction...

Tarek A Hammad, Anand Prasad
PURPOSE OF REVIEW: Critical limb ischemia (CLI) is associated with significant morbidity, mortality, and increased health care expenses. Revascularization has a central role in the treatment of CLI. Following publication of BASIL (bypass versus angioplasty in severe ischemia of the leg) trial a decade ago, an "endovascular first" approach had gained momentum and the technologies available for endovascular therapy have exponentially increased. Both the development of technology and technique, highlighted in this review, have allowed operators to treat complex infrapopliteal lesions which are central to CLI pathology...

BACKGROUND: Up to 40% of abdominal aortic aneurysms (AAAs) have coexistent iliac artery aneurysms (IAAs). In the past, successful endovascular repair required internal iliac artery (IIA) embolization, which can lead to pelvic or buttock ischemia. This study describes a technique that uses a readily available solution with a minimally altered off-the-shelf bifurcated graft in the IAA to maintain IIA perfusion. METHODS: From August 2009 to May 2015, 14 patients with AAAs and coexisting IAAs underwent repair with a bifurcated-bifurcated approach...

BACKGROUND: Superior vena cava (SVC) syndrome is a major complication that occurs when a growing lung malignancy compresses the SVC extrinsically. Current treatment options include radiotherapy or chemotherapy to shrink the tumor or endovascular stenting of the SVC to restore flow. Herein, we report a case series treated in a single institution to demonstrate the safety, effectiveness, and outcomes of salvage and primary stenting for malignant SVC obstruction. METHODS: A total of 12 male patients with malignant superior vena cava obstruction caused by lung cancer underwent SVC stenting from October 2009 to May 2015...
