Only pediatric MMD cases aged between 3 and 19 years with pre- and post-operative imaging examinations including digital subtraction angiography and magnetic resonance imaging were enrolled in this study. The main trunk vessels' stenosis and the collaterals from the superficial-meningeal system and deep parenchymal system were evaluated before and after CBS.<\/jats:p><jats:p>\n          Results\u2003During short-term follow-up period after the unilateral CBS, the stenosis of main trunk vessels both in operative (5.7\u2009\u00b1\u20092.1 vs. 6.8\u2009\u00b1\u20091.8; p\u2009&lt;\u20090.001) and non-operative hemisphere (non-operative side 4.3\u2009\u00b1\u20091.9 vs. 5.7\u2009\u00b1\u20092.1; p\u2009&lt;\u20090.001) progressed obviously. During the median follow-up period of 28.5 months after CBS, the decrease of posterior cerebral artery middle cerebral artery (PCA-MCA) anastomoses was much more significant (26 vs. 6, p\u2009&lt;\u20090.001) than that of the PCA anterior cerebral artery anastomoses (18 vs. 19, p\u2009=\u20090.807). Meanwhile, the subependymal anastomotic network could be relieved obviously (27 vs. 2, p\u2009&lt;\u20090.001), while the inner thalamic and striatal anastomotic network showed no significant change (31 vs. 25, p\u2009=\u20090.109).<\/jats:p><jats:p>\n          Conclusions\u2003The successful CBS could decrease the collaterals from the PCA-MCA leptomeningeal system and the subependymal compensations in deep parenchyma significantly, while the main trunk stenosis would aggravate rapidly both in operative and non-operative hemisphere in short-term follow-up after unilateral CBS. Therefore, strict and regular follow-ups for the changes of vascular architecture and prompt surgical intervention for the contralateral side might be of benefit to pediatric MMD.<\/jats:p>","DOI":"10.1055\/a-1753-2634","type":"journal-article","created":{"date-parts":[[2022,1,28]],"date-time":"2022-01-28T01:19:40Z","timestamp":1643332780000},"page":"188-194","source":"Crossref","is-referenced-by-count":1,"title":["Vascular
