VTE was defined as deep vein thrombosis (DVT) and pulmonary embolism (PE) within 6 months of surgery. Multivariate logistic regression was used to determine factors predictive of postoperative intracranial haematoma\/VTE. Propensity score matching (PSM) was used in group comparisons.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>One thousand five hundred fifty-one patients were included with a median age of 52 years (range 16\u201389 years) and female predominance (62%). Postoperative chemoprophylaxis was used in 81% of patients at a median of 1 day postoperatively. There were 12 VTE events (1.2%), and the use of chemoprophylaxis did not negate the risk of VTE entirely (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.99) and was highest on\/after postoperative day 6 (9\/12 VTE events). There were 18 intracranial haematomas (0.8%), and after PSM, chemoprophylaxis did not significantly increase the risk of an intracranial haematoma (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.99). Patients administered chemoprophylaxis from postoperative days 1 and 2 had similar rates of intracranial haematomas (<jats:italic>p<\/jats:italic>\u2009=\u20090.60) and VTE (<jats:italic>p<\/jats:italic>\u2009=\u20090.60), affirmed in PSM.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Postoperative chemoprophylaxis represents a relatively safe strategy in patients undergoing skull base surgery.
