What is the effect of abdominal insufflation on deep vein flow?

One discussion this week involved the effect of abdominal insufflation on deep vein flow.


Reference: Yang C, Zhu L. Coagulation and deep vein flow changes following laparascopic total extraperitoneal inguinal hernia repair: a single-center, prospective cohort study. Surgical Endoscopy. 2019 Feb 11. doi: 10.1007/s00464-019-06700-6.

Summary: The authors observed morphologic change of the iliac vein during TEP procedure. The iliac vein was almost completely collapsed, which not only impaired venous return from the lower extremities but also caused vein distention. The acute distention caused vessel wall damage due to mechanical disruption of the endothelial lining. Vessel wall damage is one of Virchow’s triad in the pathogenesis of thrombosis.

In this study, activated coagulation and impaired deep venous flow implied that the TEP procedure had a certain degree of potential risk for DVT during the early postoperative period.
