A Case Report of Umbilical Vein Varix with Thrombosis: Prenatal Ultrasonographic Diagnosis and Management

Figure 4

Pathological findings. In the middle of the umbilical cord, there is an area of vascular engorgement (125 mm in length) with central UVV. Cross-section of the cord shows occlusion of one of the umbilical arteries by a fibrin thrombus (a) with central calcification (b). Umbilical vein on both sides of the UVV is markedly dilated (c, e). The UVV, measured 25 x 11 mm, contains a large fresh thrombus (d).
