To investigate the safety and efficacy of ticagrelor in patients with critical limb ischemia (CLI) and high on-clopidogrel platelet reactivity (HCPR) undergoing complex, limb-salvage, peripheral endovascular procedures (PEP).
Objectives: The aim was to perform a review of the efficacy and safety of new oral anticoagulants (NOAs) in the management of venous thromboembolism (VTE).
Background: Acute kidney injury (AKI) after open repair (OR) and endovascular repair (EVAR) of abdominal aortic aneurysm (AAA) is associated with increased mortality and hospital costs. Early detection of AKI is critical to prevent its progression. Recent findings demonstrate that elevated levels of urinary cystatin C (uCysC) may reflect tubular dysfunction. We prospectively evaluated whether uCysC can detect renal dysfunction earlier than serum creatinine (sCr).
Background: The occurrence of cardiovascular diseases in the group of patients undergoing vascular surgery because of abdominal aorta aneurysm is very high. Endovascular procedures are regarded as hemodynamically safer for the patients. The aim of this study was to compare the changes in electrophysiological, hemodynamic, and metabolic parameters depending on the type of operation, using invasive hemodynamic monitoring and Holter electrocardiography recording.
Background: Carotid endarterectomy (CEA) is the gold standard for treating severe carotid artery stenosis, whereas carotid artery stenting (CAS) represents an endovascular alternative. The objective of this study was to assess the potential neural damage following open or endovascular carotid surgery measured by peripheral blood concentration of 3 biomarkers: S100β, matrix metalloproteinase-9 (MMP-9), and d-dimer.
Background: Endovenous laser ablation (EVLA) of the saphenous vein has become one of the preferred treatments for treating saphenous vein reflux that has resulted in symptomatic lower extremity venous insufficiency or varicose veins. This procedure was noted during initial reports to have a low incidence of postoperative thrombosis of the femoral or popliteal vein adjacent to the treated great saphenous vein (GSV) or small saphenous vein (SSV). Later clinical experience suggested that the actual incidence of this event is higher and it was subsequently termed endothermal heat-induced thrombosis (EHIT).
Endovascular treatment of posttraumatic pseudoaneurysms has become a viable less-invasive option when compared with open repair. In this study, we present a case of a posttraumatic pseudoaneurysm of the posterior tibial artery in a 34-year-old man treated with endovascular stent grafting. An extensive review of the literature has been performed.
An 81-year-old man presented with rapid enlargement of a 2-year known abdominal aortic and common iliac aneurysms. A hybrid approach to preserve both hypogastric arteries (HAs) was planned: a bifurcated endograft for the right aortoiliac axis, right femoral–to–left femoral artery bypass, and left external–to–internal iliac artery stent graft placement. Urethral stenosis requiring an epicystostomy rendered this approach not feasible. After left HA embolization, a bifurcated endograft was deployed for the abdominal aortic aneurysm exclusion. The endograft right limb was extended using a second bifurcated endograft for the ipsilateral aortoiliac axis. Surgical femoral accesses were used for the 2 bifurcated endografts and left HA embolization. Through the left brachial access, 2 stent grafts were used to preserve the right hypogastric artery revascularization. The 5-year follow-up computed tomography scan demonstrated complete aneurysm exclusion and HA patency.
Penetrating aortic trauma is associated with high mortality rates. We report the case of a 24-year-old man who presented with a self-inflicted abdominal aortic penetration injury, resulting in a pseudoaneurysm. Rather uniquely, he was managed through prophylactic stenting to his abdominal aorta; this case was also rare in that there were remarkably no associated visceral injuries. Stenting was preferred because of risks of an aortic graft in a young man. A 14-mm Atrium Advanta™ stent was deployed, and angiography confirmed adequate exclusion of the pseudoaneurysm. He had no complications at follow-up.
A 79-year-old man with a previous endovascular aneurysm repair (EVAR) for a 5.4-cm abdominal aortic aneurysm presented 3 years after the procedure with sudden onset lower limb paralysis and pain. The diagnosis of acute aortic thrombosis within the aortic prosthesis graft was made and confirmed on computed tomography. Thrombolysis delivered into the graft via a radiologically placed catheter successfully dissolved the thrombus and resulted in improvement of the patient´s symptoms. We discuss the presentation of, and role in management of thrombolysis in, this rare complication of aneurysm repair.
Axillofemoral graft reconstructions were initially intended to restore lower extremity perfusion in high-risk patients with symptomatic aortoiliac atherosclerotic occlusive disease. However, these reconstructions are now relegated to “bailout” procedures for infected grafts or high-risk critical limb ischemia patients that fail endovascular therapy. Infection of an extra-anatomic bypass graft is a challenging complication as it occurs in poor operative candidates with limited revascularization options and failure has a high rate of amputation and mortality. Described is a novel approach using endovascular reconstruction to treat symptomatic Trans-Atlantic Inter-Society Consensus-II type D aortoiliac lesions allowing for complete excision of an infected axillobifemoral bypass.
Long-term mechanical circulatory support devices are currently an established therapy for the management of end-stage heart failure, and current evidence supports their superiority in comparison to maximal medical therapy in these patients. Screening for peripheral arterial disease and abdominal aortic aneurysm (AAA) before left ventricular assist device (LVAD) implantation is recommended. Although repair of AAA before or during LVAD placement has been reported, management of patients with AAA after LVAD implantation needs to be further investigated. We describe our management and operative strategies in 2 patients on destination LVAD therapy who underwent successful endovascular AAA repair.
With an increase in the population of living cardiac allograft recipients, noncardiac surgery in this group of patients will be a more frequent phenomenon. The postoperative management in these patients is, however, complex. The authors present a case of an abdominal aortic rupture due to the involvement of a necrotizing pancreatitis caused by the side effects of immunosuppressive therapy. A 48-year-old man presented with a necrotizing pancreatitis with accidental affection of the abdominal aortic wall, necessitating emergency repair. Open surgical repair was considered too precarious in a cardiac allograft recipient, aortic stent-graft through endovascular surgery was therefore opted as the preferred procedure. The subsequent postoperative course was uneventful and patient could be discharged.
Iatrogenic injury of the inferior vena cava (IVC) is a rare event with potentially devastating sequelae. Only a handful of case reports are available in the literature describing successful endovascular techniques to manage this complication. We present the case of a patient with injury to the retrohepatic IVC resulting in life-threatening hemorrhage which was controlled with endovascular stent grafts.
Objective: Cranial nerve palsy (CNP) and neck haematoma are complications of carotid endarterectomy (CEA). The effects of patient factors and surgical technique were analysed on the risk, and impact on disability, of CNP or haematoma in the surgical arm of the International Carotid Stenting Study (ICSS), a randomized controlled clinical trial of stenting versus CEA in patients with symptomatic carotid stenosis.
