Although carotid stenting is an effective treatment for severe carotid stenosis, it has been associated with alterations in autonomic functions during or shortly after the procedure. Heart rate variability (HRV) is an established tool for the asessment of autonumic functions. In this study, our aim was to investigate the relation ...

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 ...

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. Research: Cross-sectional study of men and women with SCIs compared to able-bodied controls. Subjects included 105 ...

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. ...

OBJECTIVE: To assess the safety of the suprabrow approach (SBCA) for aneurysm surgery by comparing intraoperative rupture rates with those for the standard pterional approach. METHODS: A systematic review of all literature published in or after 1997 was performed using specified search words. All papers that described aneurysm surgery by ...

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 ...

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 ...

Double aortic aneurysm (DAA) falls under the category of multiple aortic aneurysms. Repair is generally done through staged surgery due to low invasiveness. In this approach, one aneurysm is cured per operation. Therefore, two operations are required for DAA. However, post-first-surgery rupture cases have been reported. Although the problems involved ...

Harms technique of C1-C2 fixation for atlantoaxial complex becomes more popular due to good fusion rate and low vertebral artery injury (VAI) rate. But considering the unique and variable anatomy of atlantoaxial complex, iatrogenic VAI will result in catastrophic consequences and provides particular surgical challenges for surgeons. To our knowledge, ...
