RE: “Long-term follow-up of stenting across the ilio-caval confluence in patients with iliac venous lesions”: the value of using IVUS and a dedicated oblique venous stent for deep vein work involving the ilio-caval bifurcation

We read with interest the paper by Zhang et al. investigating the safety and patency of iliac vein stents extending into the inferior vena cava (IVC), which demonstrated a very low incidence of thrombosis in the contralateral iliac vein (0.55% or 1/183 patients) . The incidence of contralateral deep vein thrombosis (DVT) in this study is remarkably lower than previously published data (1–9.7%) [2, 3], especially as the cohort contained both thrombotic and non-thrombotic iliac vein lesions. Concerns regarding contralateral DVT after common iliac vein (CIV) stent placement in patients with May-Thurner Syndrome (MTS) was recently highlighted by Le et al. . The authors showed that the incidence of contralateral DVT after CIV stent placement was relatively high in their retrospective analysed series [10/111 (9%) patients] and typically occurred late during follow-up (median time of approximately 40 months). They identified that over extension of the CIV stent into the IVC...
