Abstract

Background and aims: Women present with pulmonary embolism (PE) more often than men, while the opposite is true for proximal deep vein thrombosis (DVT). We investigated whether sex-specific differences exist in the presenting location of acute symptomatic DVT among patients without concomitant PE. Methods: We tested our hypothesis in a meta-analysis of studies selected by systematically reviewing PubMed, Embase, and the grey literature. Thereafter, we analysed data of a single-center cohort including patients with first isolated acute DVT to assess the additional impact of age and provoking risk factors on the presenting location of DVT. Results: We identified 7 studies for a total of 20,534 patients. The weighed pooled absolute difference in the proportion of distal DVT between women and men was +5.4% (95%CI: +0.7%; +9.5%), which corresponds to a pooled odds ratio (OR) of 1.30 (95%CI: 1.07–1.58). This difference was +6.5% (95%CI: +2.1%; +10.9%) for first distal DVT (OR 1.38; 95%CI: 1.11–1.72) and +5.3% (95%CI: +0.5%; +10.0%) for either first or recurrent distal DVT (OR 1.29; 95%CI: 1.03–1.61). In the cohort study, the larger difference in the proportion of distal DVT between women and men was observed among patients aged 51–70 (+9.5%; 95CI: +2.8%; +16.0% compared to those aged 18–50) or with unprovoked events (+8.5%; 95CI: −0.9%; +17.9%). Conclusions: Among patients with first symptomatic isolated acute DVT, women presented with distal DVT more often than men, whereas men had a higher proportion of proximal DVT events. This pattern appeared to depend on age and the absence of provoking risk factors for VTE.
