Although aneurysm neck ligation and aneurysmectomy with reconstruction are sometimes performed for SAAs in the main trunk of the splenic artery, arterial reconstruction is unnecessary, because the spleen has abundant collateral circulation via the short gastric arteries; thus, coil embolization by EVT, which has a high success rate and less risk of ischemia, may be appropriate (Fig. 2) [48]. This evidence concerns the gene PCSK1N and ischemia.
