One of the challenges in coarctation stenting, particularly in covered stents
, is to preserve flow to left subclavian artery as its usually originates very close to coarctation segment.
Although, its incidence has decreased with covered stents
, but growth can occur proximal or distal to the stent and through the flanges.
To avoid these severe complications, covered stents
have been used to maintain perfusion, which is particularly important in patients at risk of portal vein thrombosis.
6,7) Recently, endovascular repair of PFA hemorrhage or false aneurysm with covered stents
have become feasible.
10 Contrarily, EVAR is performed under real-time monitoring to lead an appropriate covered stent
into the abdominal aorta through the femoral artery, aiming to cover the proximal-and distal-end aneurysm necks.
Figs 4 and 5 are images showing a bare metal stent and covered stent
grafts (Viabahn), respectively.
Although stent placement in patients with benign and malignant disease remains controversial, (18,27,28) rigid application of aggressive resuscitation is not always appropriate and, when it is not, may be replaced by covered stent
placement and/or compassionate support.
