Abstract
Monochorionicity is responsible for an increased rate of severe complications because of unequal splitting of the placental mass and/or an imbalance in the blood flow across placental vascular anastomoses. Vascular limb occlusion is one of the rare complications of monochorionic twins, usually occurring in the lower extremities after intra-uterine death of one twin, antenatal intervention (amnio-reduction or laser therapy) or in the presence of twin anemia-polycythemia syndrome. We report a case of vascular occlusion of the upper extremity in the recipient twin of a monochorionic pair in the absence of those predisposing factors.
