Treatment of twin-twin transfusion syndrome (TTTS) via the sequential selective laser photocoagulation of communicating vessels (SQLPCV) technique involves lasering the arteriovenous communications from the donor twin to the recipient twin first, followed by the arteriovenous communications from the recipient twin to the donor. Occluding the vascular communications in this particular order may result in transient intraoperative net transfusion to the donor twin and facilitate hemodynamic equilibrium, particularly to the volume depleted donor twin. Preliminary evidence suggests that the SQLPCV technique may result in improved perinatal outcomes compared with the standard selective (SLPCV) laser surgical approach. In this article, we describe the pathophysiological basis for this surgical approach, delineate the surgical technique, review the literature, and elaborate on the outstanding questions of the SQLPCV treatment of TTTS.
