The time it takes for a cyst to form in a uterine arteriovenous fistula varies among individuals, ranging from weeks to months. Generally, it is related to factors such as the severity of the condition, the degree of abnormal blood flow, and whether timely treatment is received. Early detection and intervention can effectively prevent the formation of cysts and their related complications.
Uterine arteriovenous fistula is a pathological condition characterized by abnormal connections between arteries and veins within the uterus, which may lead to complex situations such as abnormal blood flow and uterine cavity dilatation. If blood flow disturbances are not resolved in a timely manner, they may further contribute to blood stasis and local tissue damage, ultimately resulting in the formation of fluid-filled cysts. The formation of cysts is often associated with untreated uterine trauma, postpartum hemorrhage, surgical history, or uterine cavity infections. In addition to cysts, uterine arteriovenous fistulas may manifest as irregular vaginal bleeding, pelvic pain, or rarely, massive bleeding. Imaging studies such as color Doppler ultrasound and angiography can clarify the extent and nature of the lesion, providing a basis for step-by-step treatment.
For uterine arteriovenous fistulas, treatment options include pharmacological control, interventional therapy, or surgery. Pharmaceutical treatment includes drugs that normalize blood vessels, such as hemostatic agents or hormone regulation, which may be effective in mild stages. Interventional therapy, such as embolization surgery, can precisely close abnormal vascular connections and is a minimally invasive option. In severe cases, hysterectomy may be required to address the problem definitively. Important measures to prevent cysts and complications caused by fistulas include regular check-ups. If there is unexplained vaginal bleeding or abdominal pain, medical evaluation should be sought promptly.
