Objectives: The purpose of CONFIRM registry series was to evaluate the use of orbital atherectomy (OA) in peripheral lesions of the lower extremities, as well as optimize the technique of OA.
Objectives: To appraise clinical results of foot arteries recanalization using percutaneous retrograde transmetatarsal arteries access followed by retrograde recanalization of foot and tibial vessels.
Objectives: This study was designed to evaluate the safety of a novel drug-coated balloon (DCB) with 2 µg/mm2 paclitaxel and a carrier comprised of polysorbate and sorbitol in a swine femoral artery model.
Acute limb ischemia (ALI) is caused by embolisms or progressive atherosclerosis. We report the case of a 68-year-old female who presented with acute total occlusion of left iliac artery due to remarkably massive ascites from pancreatic cancer. To our knowledge, no other case reports of ALI caused by acute compartment syndrome have been published. We treated our case successfully by draining the ascites fluid without any balloon angioplasty or stent implantation. The removal of extrinsic compression may be the best treatment for cases of this type. © 2013 Wiley Periodicals, Inc.
Long saphenous femoral artery (SFA) chronic total occlusions (CTOs) are considered the “Achilles heel” of the lower extremity percutaneous interventions. Antegrade, retrograde, or transcollateral approaches, intraluminal or subintimal techniques with re-entry and specialized CTO devices using microdissection, vibrational energy, and laser have all been tried for the management of such challenging lesions with various success rates. Ocelot is the first CTO crossing device using real-time OCT technology. Its crossing catheter utilizes spiral wedges to corkscrew the CTO cap, while real-time OCT offers direct visualization to facilitate intravascular true-lumen orientation. The recently presented results of the CONNECT-II study demonstrated crossing success of 97% and freedom from major adverse events of 98%. We present one of the most challenging SFA CTOs with ambiguous proximal cap in the ostium of the SFA, heavy calcification and involving almost the entire length of the SFA. The Ocelot catheter assisted to the successful true-lumen recanalization of that complex lesion. © 2013 Wiley Periodicals, Inc.
Objectives: Ideally, guidewires used during peripheral vasculature (PV) interventions could serve both as a therapy delivery platform and a diagnostic tool for real-time vessel sizing (2-in-1 function).
Objective: To identify the specific caseload to overcome learning curve effect based on data from consecutive patients treated with Intracranial Angioplasty and Stenting (IAS) in our center.
Iatrogenic arteriovenous fistula is not a common complication of central venous catheterization. Duct occluder devices have been developed for patent ductus arteriosus occlusions but they may be used for arteriovenous fistula closures. We report a case of iatrogenic brachiocephalic-jugular and aortopulmonary artery fistulas after central venous catheter insertion. The fistulas were successfully managed with duct occluder devices. Due to increasing number of central venous catheterizations, physicians should be aware of this uncommon complication. Transcatheter closing of brachiocephalic-jugular and aortopulmonary artery fistulas by duct occluder devices seems to be a safe and feasible form of treatment. © 2013 Wiley Periodicals, Inc.
Retroperitoneal fibrosis is a rare condition characterized by the presence of inflammatory and fibrous retroperitoneal tissue that surrounds and often encases abdominal structures. In this report we describe an unusual presentation of retroperitoneal fibrosis and inferior vena cava (IVC) obstruction that was unidentified by noninvasive testing and ultimately diagnosed using exercise right heart catheterization and venography. Exercise hemodynamic catheterization revealed a high pressure gradient across the IVC obstruction during exercise that resulted in reduced preload and inappropriately low cardiac output reserve. The patient ultimately underwent angioplasty and stenting of the obstruction resulting in resolution of his symptoms. © 2013 Wiley Periodicals, Inc.
Background: Statins stabilize atherosclerotic plaque, decrease mortality after surgical procedures, and are linked to anti-inflammatory effects. The objective of this study was to evaluate preoperative administration of statins and longitudinal limb salvage after lower extremity endovascular revascularization and lower extremity open surgery.
Background: Recent technical advances have made endovascular treatment (EVT) an alternative first-line treatment for critical limb ischemia.
Peripheral artery disease (PAD) is one of the most common cardiovascular diseases and is associated with high short-term morbidity and mortality.1,2 It is the primary cause of lower extremity amputation throughout the world and is a powerful marker of advanced systemic atherosclerosis. Chronic critical limb ischemia (CLI) represents the most advanced clinical manifestation of PAD and is defined by the presence of ischemic rest pain, nonhealing wounds, or tissue loss (gangrene). CLI does not represent a single pathophysiologic process (ie, progressive leg arterial atherosclerosis), but is caused by multiple pathogenetic mechanisms, including native artery atherosclerosis, cardioembolic events, inflammatory arteritides (eg, thromboangiitis obliterans), hypercoagulable states, or leg bypass graft failure.
Background: Endovascular repair of the thoracic aorta has become an increasingly utilized therapy. Although the short-term mortality advantage over open surgery is well documented, late mortality and the impact of presenting pathology on long-term outcomes remain poorly reported.
Objectives: Inadvertent intra-arterial injection of flunitrazepam tablets intended for intravenous use by drug abusers has devastating effects. We report here on the clinical outcome of 16 drug abusers developing critical limb ischaemia after flunitrazepam injection.
Objective: To evaluate the feasibility, safety, and effectiveness of single-session endovascular treatment with manual aspiration thrombectomy (MAT) as the first-line method of thrombus removal for iliac vein compression syndrome (IVCS) with secondary acute isolated iliofemoral deep vein thrombosis (DVT).
