The change of blood supply pattern in visceral arteries of Stanford B dissection after endovascular repair / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To discuss the change of blood supply pattern in visceral arteries of Stanford B dissection. The visceral arteries include celiac trunk (CA), superior mesenteric artery (SMA) and renal artery (RA).</p><p><b>METHODS</b>By retrospectively analysing the clinical data of 52 cases with Stanford B dissection, the blood supply pattern of visceral arteries was confirmed by aortography and the changes before and after endovascular repair were compared.</p><p><b>RESULTS</b>After repair the stenosis lesions disappeared in 7 cases supported by true channel completely but one. Twenty-two visceral arteries supported by true and false channel simultaneously recovered true channel chiefly but one. One recovered true channel chiefly and one had no change in 2 visceral arteries supported by false channel completely. Four recovered true channel chiefly and one had no change in 5 visceral arteries without blood support. 88.9% blood support got better and 11.1% blood support had no change in 36 damaged visceral arteries after endovascular repair.</p><p><b>CONCLUSION</b>Blood support from true and false channel simultaneously is the chief pattern in the injured visceral arteries before repair; Endovascular repair technique is benefit to recovering the blood support of true channel.</p>
