Preoperative intracranial hemorrhage represents a severe and catastrophic complication in adult patients with MMD, while reliable strategies for precise risk stratification are still lacking to date. Furthermore, the potential association of lipid metabolic indices with preoperative hemorrhagic risk in MMD remains poorly clarified and insufficiently explored.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A retrospective multicenter study was conducted enrolling 260 adult MMD patients recruited from two medical centers during 2015\u20132025.

Univariate analysis, LASSO regression with 10-fold cross-validation, and multivariate logistic regression were sequentially performed to screen and determine independent risk factors. A predictive nomogram was further constructed, and its predictive performance was comprehensively validated via receiver operating characteristic (ROC) curve, calibration curve, decision curve analysis (DCA), and clinical impact curve (CIC).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Elevated LDL-C was confirmed as an independent risk factor for preoperative hemorrhage (OR\u202f=\u202f2.46, 95%CI: 1.41\u20134.28,\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.002). Restricted cubic spline regression demonstrated a linearly positive correlation between LDL-C, TC and preoperative hemorrhagic risk, with optimal cut-off values of 3.5\u202fmmol\/L and 5.0\u202fmmol\/L, respectively. The ROC showed moderate discriminative value with an AUC of 0.78 (95%CI: 0.72\u20130.85), accompanied by satisfactory sensitivity, specificity and favorable clinical net benefit.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Elevated LDL-C is independently correlated with the occurrence of preoperative hemorrhage in adult MMD patients.
