The angiographic and IVUS grayscale results in a lateral aneurysm model in the right CCA managed with a magnesium alloy covered stent.
(A) Preoperative DSA shows a lateral aneurysm (arrow) at the upper portion of the CCA. (B) DSA immediately after stent placement exhibits disappearance of the aneurysm, with slight stenosis of the right CCA (double arrow); (C) The IVUS grayscale results of different parts of the normal CCA and stented CCA artery immediately after stent placement. (D) DSA 6 months after stent placement shows the disappearance of the aneurysm, without obvious stenosis of the stented CCA. (E) The IVUS grayscale results show that the lumen area in the stented CCA is increased compared with the lumen area immediately after stent placement. (F) DSA 12 months after stent placement displays disappearance of the aneurysm, with patency of right CCA. (G) The IVUS grayscale results also show that the lumen area in the stented CCA has increased as compared with the lumen area immediately after stent placement. Note: 1 = Normal CCA 5 mm distal to the stent; 2 = distal portion of the stented CCA; 3 = middle portion of the stented CCA; 4 = proximal portion of the stented CCA; 1 = normal CCA 5 mm proximal to the stent.
