Morphological Changes of the Ovarian Vein in Pelvic Venous Disorders

Popis výsledku v původním jazyce

OBJECTIVE: Management of pelvic venous disorders (PeVD) is still controversial. Open surgical and endovascular methods are currently used for treatment, but there are few data in the literature on the morphology and histology of the ectatic ovarian vein (OV). This study aimed to explore the histomorphological changes in a dilated OV in patients with PeVD and compare it with a normal OV obtained post-mortem and a normal great saphenous vein (GSV). METHODS: Histology of the OV was studied in 16 patients who underwent surgery due to PeVD, 10 control cadavers from whom fragments of the OV without visible gross changes were taken at autopsy, and nine control patients in whom the GSV was resected to be used for coronary artery bypass. RESULTS: The OV wall in patients with PeVD consisted of three layers: intima, media, and adventitia. The OV looked very similar to the GSV wall because of a clearly developed layer of smooth muscle fibres. The thickness of the normal OV was significantly different to the OV wall in PeVD (475.3 μm, IQR 370.7, 607.6 vs. 776.3 μm, IQR 668.9, 879.6, p &lt; .001) and did not significantly differ from thickness of a normal GSV wall (784.3 μm, IQR 722.2, 898.2). The intima-media complex of the OV was significantly thinner than the GSV in PeVD (118.9 μm, IQR 75.6, 159.6 vs. 415 μm, IQR 399.5, 520.0, r &lt; .001); however, the adventitia of the OV was significantly thicker than in normal OV and GSV (599.6 μm, IQR 444.3, 749.7 vs. 373.5 μm, IQR 323.8, 482.0 vs. 308.4 μm, IQR 275.9, 338.2, p &lt; .001). CONCLUSION: Dilatation of the OV in patients with PeVD was accompanied by a significant increase in the overall thickness of the vein wall, which brings it closer in structure to the GSV. This implies that the OV may be safely used for transposition into the inferior vena cava or iliac vein.
