Results: A total of n=701 individuals with n=930 stents with median age of 60 (interquartile range (IQR): 26–89) years and male predominance 3.5 : 1 were identified in n=30 articles. The most common venographic classification was Stanford type II (n=344, 50%) and complete symptomatic resolution was achieved in 48 h. The 30-day morbidity was (n=62, 8%) and mortality was (n=21, 3%). Female gender was associated with higher 30-day morbidity (p<0.03). The cumulative median patency of Wallstent for non-malignant aetiology was [550 days (IQR: 14–1080) vs. 120 days (IQR: 0–925)] for malignancy (p<0.03).
