Low-coordination wake-up algorithms for multiple connected-covered topologies in sensor nets

It is likely that low cost energy constrained sensor devices will be prone to failure. This neccessitates that these devices must be deployed in higher densities than required. At a high level, the simplest strategy that can be exploited to prolong network lifetime is to activate only a subset of nodes at a time, while keeping the other nodes asleep, so that the topology formed by the active no...

Iatrogenic femoral arteriovenous fistula: endovascular treatment with covered stent implantation and 4-year follow-up.

Puncture site complications such as arteriovenous fistula after femoral arterial catheterizations are becoming more common with the increasing number of endovascular procedures being performed by interventional radiologists and cardiologists. Covered stent placement with endovascular technique for these lesions represents an appealing treatment alternative because it is only minimally invasive ...

Long-term follow-up study of elderly patients with covered stent implantation after coronary perforation

OBJECTIVE To evaluate the long-term efficacy of covered stent implantation in the treatment of elderly patients with coronary perforation while undergoing percutaneous coronary intervention (PCI). METHODS From June 2004 to June 2012, our center has followed ten elderly patients (age ≥ 60 years) who sustained coronary perforation during PCI. The major adverse cardiac events (MACE) were observe...

Long-term follow-up of endovascular treatment of renal artery aneurysms with covered stent deployment.

BACKGROUND The aim of this study was to assess the technical success and clinical long-term results of renal artery aneurysm (RAA) treatment using covered stents. METHODS We performed a retrospective study on endovascular treatment of nine patients with 10 RAAs, arising from the main renal artery or from the proximal portion of large segmental arteries. All procedures were performed in our de...
