Tiny wireless implant detects oxygen deep within the body

(University of California - Berkeley) Engineers at the University of California, Berkeley, have created a tiny wireless implant that can provide real-time measurements of tissue oxygen levels deep underneath the skin. The device, which is smaller than the average ladybug and powered by ultrasound waves, could help doctors monitor the health of transplanted organs or tissue and provide an early warning of potential transplant failure.

This study was aimed to evaluate a novel surgical approach to renal allograft revascularization, taking into consideration the length of time elapsed since transplantation. We describe an arterial bypass using a polytetrafluoroethylene (PTFE) graft from the common iliac artery (proximal to the renal artery implantation) to the external iliac artery (distal to the renal artery implantation) that allows the adequate revascularization of both the transplant kidney, as well as the lower extremity. This technique provides several advantages when compared with previously described procedures to revascularize a transplanted kidne...

AbstractThe relationship between arteriovenous access flow (Qa) and cardiovascular changes is complex. Several studies have shown cardiac remodeling and symptoms of heart failure for high-flow arteriovenous fistulas (AVF). To evaluate the early cardiovascular impact of AVF. Forty-seven patients with an AVF, hospitalized for the evaluation of high-flow AVF or a pre-kidney transplant assessment were included. We collected clinical and biological data. We also collected data of the assessment by transthoracic echocardiography, functional evaluation by 6-min-walk test and peak oxygen consumption, and measurement of coronary fl...

AbstractBackgroundDoppler US is the primary screening for post-liver transplant vascular complications, but indeterminate findings require further imaging.ObjectiveTo evaluate whether contrast-enhanced US improves diagnostic assessment of vascular complications suspected by Doppler US.Materials and methodsWe retrospectively reviewed Doppler US and contrast-enhanced US studies obtained in the first week following liver transplant. Doppler US was performed twice daily for the first 5 postoperative days, and CEUS in the first postoperative day and when vascular complications were suspected. We correlated Doppler US and CEUS w...
