The challenge to detect heart transplant rejection and transplant vasculopathy non-invasively – a pilot study

Journal of Cardiothoracic Surgery, 2009
Background Cardiac allograft rejection and vasculopathy are the main factors limiting long-term survival after heart transplantation. In this pilot study we investigated whether non-invasive methods are beneficial to detect cardiac allograft rejection ...

Clipping of spinal arteriovenous fistula of the filum terminale under intraoperative angiography guidance

Formosan Journal of Surgery, 2019
Arteriovenous fistula of the filum terminale (AVFFT) is an uncommon disease. We reported a case of this rare condition and we used intraoperative angiography to identify the completeness of fistula obliteration. A 53-year-old man presented with a history
