Total aortic arch replacement remains a complex surgical procedure, best practiced in high-volume aortic centers. The following report details the surgical procedure for total arch replacement with selective antegrade cerebral perfusion (SACP) for distal arch aneurysm. Following moderate hypothermic circulatory arrest and SACP, the distal arch, and then the proximal ...

Transapical transcatheter aortic valve replacement (TAVR) is a new minimally invasive technique with a known risk of unexpected intra-procedural complications. Nevertheless, the clinical results are good and the limited amount of procedural adverse events confirms the usefulness of a synergistic surgical/anesthesiological management in case of unexpected emergencies. A review was ...

BACKGROUND: Complete packing of intracranial aneurysms has demonstrated a significant decrease in aneurysm recurrence rates with increased volumetric filling. The HydroCoil Embolization System (HES) was developed to increase volumetric filling within the aneurysm sac to maintain long term occlusion. To further enhance ease of HES deployment, a new next generation ...

Trans-aortic valve replacement is a new endovascular procedure which has started to be used routinely in cardiac interventional suites. During such procedures a stent-like device containing new aortic valves is placed over the damaged ones, possibly causing calcifications to be dislodged and released in arteries leading to stroke. To prevent ...

The prevalence of abdominal aortic aneurysms (AAAs) and AAA-related deaths are steadily declining in some countries as a result of the reduction in smoking rates. It was thus suggested that screening programs that do not target high-risk populations are likely to have very low AAA detection rates. However, this may ...

As the number of endovascular peripheral arterial interventions is increasing nationwide, so is the rate of observed in-stent restenosis, specifically in the superficial femoral artery. A paucity of literature is available regarding the pathophysiology, risk factors, and therapies associated with in-stent restenosis of the superficial femoral artery. This article summarizes ...

BACKGROUND: The spread of drug-eluting stents (DES) has reduced the incidence of early restenosis following percutaneous coronary interventions (PCI). Meanwhile, development of minimally invasive coronary artery bypass surgery (MIDCAB) has offered a valuable alternative to conventional sternotomy with preservation of the benefit of the internal mammary artery use. Therefore, the ...

Paravalvular regurgitation (PVR) is a symptomatic or asymptomatic complication after surgical valve replacement. It may be related to calcification, infection or tissue friability and occurs in 5 % to 17 % of surgical implanted heart valves. Reoperation is associated with a higher morbidity and mortality than the index procedure. Percutaneous closure of ...

The current routine use of intracoronary stents in percutaneous coronary intervention (PCI) has significantly reduced rates of restenosis, compared with balloon angioplasty alone. On the contrary, small post-stenting luminal dimensions due to undilatable, heavily calcified plaques have repeatedly been shown to significantly increase the rates of in-stent restenosis. Rotational atherectomy ...

Treatment of the femoropopliteal (FP) artery remains a challenge to the endovascular specialist. Long-term patency is low with a high rate of target lesion revascularization. The true patency rate varies considerably between studies partly because there is a lack of uniform performance criteria and reporting standards in peripheral arterial interventions. ...

To investigate lower-extremity arterial hemodynamics in individuals with spinal cord injury (SCI). We hypothesized that oscillatory shear index would be altered and resting mean shear would be higher in the lower-extremity arteries of SCI. Cross-sectional study of men and women with SCIs compared to able-bodied controls. Subjects included 105 ages ...

Drug-eluting stent (DES) deployment during percutaneous coronary intervention (PCI) has reduced target-vessel revascularisation rates (TVR). The selective use of DES in patients at highest risk of restenosis may allay concerns about universal compliance of dual antiplatelet therapy for one year, and potentially reduce costs. If this strategy achieved acceptably low ...

ABSTRACT: Relatively few cases of the ectopic implantation of an amputated thumb have been reported. The majority of ectopic sites are far from the original anatomic site, and anastomosis of the artery cannot be avoided in the secondary replantation surgery, which increases the failure rate. We conducted an anatomic study ...

The presence of a severe calcified peripheral artery lesion is responsible for a poor response to balloon dilation, due to significant acute vessel recoil and frequent flow-limiting dissections requiring stent implantation. This possibility could be associated with very high compression and/or fracture rates particularly in cases of lesion located at ...

The retrograde approach is a novel technique of percutaneous coronary intervention for chronic total occlusion. This technique has improved the success rate of guidewire passage through the occlusion. In the retrograde approach, a microcatheter and balloon are delivered through a retrograde channel. However, it is difficult for a stent to ...

The endovascular treatment of abdominal aortic aneurysms has become more common. A careful comparison of this technique with the established treatment by open surgery is needed before it can be more widely adopted. We selectively searched the Medline database for articles on the endovascular treatment of abdominal aortic aneurysms, with ...

Single-segment saphenous vein remains the optimal conduit for infrainguinal revascularization. In its absence, prosthetic conduit may be used. Existing data regarding the significance of anastomotic distal vein adjunct (DVA) usage with prosthetic grafts are based on small series. This is a retrospective cohort analysis derived from the regional Vascular Study ...

Dronedarone and amiodarone are anti-atrial fibrillation agents with different potency. Pulmonary veins play a critical role in the genesis of atrial fibrillation. Oxidative stress can enhance pulmonary vein arrhythmogenesis. This study was done to compare the effects of dronedarone and amiodarone on pulmonary vein electrophysiological and mechanical properties, and oxidative ...

Although intraarterial shunting during carotid endarterectomy is a well-defined practice, its use remains controversial. Complication rates associated with shunt placement remain low, but may be underreported. When complications secondary to routine intraarterial shunting occur, they can cause significant morbidity or even mortality, emphasizing the importance of meticulous technique to prevent ...

Saphenous vein grafts (SVGs) are a common choice for bypassing obstructed coronary arteries. Repeat coronary artery bypass grafting has been found to have substantial rates of morbidity and mortality; therefore, SVG percutaneous intervention has emerged as a positive alternative for revascularization. Stenting of SVGs has been shown to be more ...

The introduction of retrievable inferior vena cava (IVC) filters was an important step in the evolution of deep vein thrombosis/pulmonary embolism management. Their removability makes them preferred to permanent filters in many cases. IVC filter retrieval often occurs at a suboptimal rate, leading to complications associated with long-term placement. Improving ...
