What describes Pelvic Congestion Syndrome (PCS)?

Pelvic Congestion Syndrome (PCS) is characterized by the presence of visceral venous reflux in the pelvic veins. This condition typically occurs when the valves in the veins of the pelvic region become incompetent, leading to the backflow of blood. As a result, it causes dilatation of the veins and can lead to chronic pelvic pain, especially in women. The symptoms of PCS often worsen during pregnancy or with prolonged standing, as increased venous pressure can exacerbate the reflux.

In contrast, arterial thrombosis involves the blockage of arteries, lymphatic obstruction pertains to issues within the lymphatic system, and arterial hypertension relates to high blood pressure in the arterial system. These conditions do not describe the mechanisms or symptoms associated with PCS, making the correct identification of visceral venous reflux crucial in understanding this syndrome.
