The Lublin protocol of the ovarian vein embolization in the management of pelvic venous disorders
This paper presents the Lublin Protocol, a comprehensive, evidence-based framework developed over fifteen years at a Polish hospital that standardizes the diagnosis, patient selection, and endovascular management of pelvic venous disorders through ovarian vein embolization to improve procedural safety and clinical outcomes.

For many women, a deep, aching pain in the lower abdomen, back, or hips is a constant companion that disrupts daily life. This is not the sharp, predictable cramping of a menstrual cycle, but a dull, persistent heaviness that often worsens when standing for long periods and eases only when lying down. For decades, doctors struggled to identify the root cause of this suffering, often attributing it to general muscle tension or unexplained inflammation. Today, medical science recognizes a specific culprit: a condition where the veins in the pelvis fail to pump blood efficiently back to the heart. Instead of flowing upward, the blood pools and leaks backward, causing the veins to swell and become varicose, much like the twisted veins seen on the legs of someone with chronic circulation issues. This pooling creates pressure and pain that can radiate to the groin, thighs, and even the vulva. While the problem is physical and visible on scans, finding it requires a keen eye, and treating it without major surgery has remained a complex challenge for specialists.
In a hospital in Lublin, Poland, a team of gynecologists, radiologists, and vascular surgeons has spent fifteen years refining a specific method to solve this problem. They have treated more than one thousand patients using a procedure called ovarian vein embolization, a minimally invasive technique that blocks the faulty veins from the inside. The team has now published a detailed guide, known as the Lublin Protocol, which lays out a strict, step-by-step roadmap for how to identify the right patients, how to perform the procedure safely, and how to ensure the pain does not return. This is not a new discovery of a disease, but rather a standardization of a cure. The authors argue that while the treatment works, the way doctors have been selecting patients and performing the surgery has been too varied, leading to inconsistent results. Their goal is to replace guesswork with a precise, repeatable system that anyone trained in the field can follow.
The journey begins long before a patient enters the operating room. The protocol insists that no one should undergo this procedure without first trying a three-month course of conservative care. This includes wearing compression stockings, taking medications to support vein health, and making lifestyle changes like losing weight if necessary. Only if the pain remains stubborn after this trial does the patient move to the next stage. The doctors then conduct a rigorous interview, asking about the exact nature of the pain, its timing, and what makes it better or worse. They look for specific signs, such as pain during or after sex, or a feeling of urgency to urinate. Crucially, they use a specialized ultrasound scan to look inside the pelvis. They are not just looking for swollen veins; they are measuring them. If a vein is wider than five millimeters, if the blood is moving too slowly, or if it is flowing backward for more than one second, the scan flags the problem. If a patient shows four of these specific signs, the doctors are nearly certain the diagnosis is correct.
Once a patient is selected, a team of three specialists—a gynecologist, an interventional radiologist, and a vascular surgeon—must all agree that the procedure is the right choice. This multidisciplinary check ensures that the pain is truly coming from the veins and not from another hidden cause. The procedure itself is performed while the patient is awake, using only local anesthesia to numb the skin. The doctor makes a tiny puncture, usually in the neck or the groin, and threads a thin tube through the blood vessels until it reaches the faulty vein. They first inject a special dye to take a live X-ray video, mapping the exact path of the blood flow and confirming where the leak is happening. This step is vital because the anatomy of these veins can vary greatly from person to person, and sometimes the blood flow is more complex than it appears on a standard scan.
The actual repair involves two distinct actions working in tandem. First, the doctor fills the swollen, leaking veins with a foam made from a sclerosing agent. This foam pushes the blood out of the way and coats the inside of the vein, causing the walls to stick together and seal shut. Because the foam is thick, it stays in place longer than a liquid would, ensuring the entire length of the damaged vessel is treated. Once the foam has done its work, the doctor places small metal coils into the main trunk of the vein, acting like a plug to stop any new blood from entering the damaged area. The team emphasizes a specific order: they treat the smallest, most distant branches of the vein first with the foam, and then block the main supply line with the coils. This prevents the blood from simply finding a new path around the blockage. The entire process is designed to be completed in a single day, with the patient going home the same evening.
After the procedure, the focus shifts to recovery and verification. Patients are instructed to rest for a few weeks and continue wearing compression stockings. They return to the clinic at three and six months for a thorough check-up. The doctors repeat the ultrasound scan to see if the veins have stayed closed and if the blood flow has normalized. They also ask the patient to describe their pain levels again. The data from the Lublin center suggests that for the majority of patients, this approach brings significant relief. However, the authors are careful to note that the treatment is not a magic bullet for everyone. Some patients may still feel pain, which could mean the problem lies elsewhere or that the veins have reopened. In those cases, the protocol dictates a careful re-evaluation rather than a blind repetition of the surgery.
The paper concludes by acknowledging that while the results from Lublin are promising, the broader medical community needs more consistent data. Many past studies have been small or looked at patients in different ways, making it hard to compare results. By laying out this clear, unified protocol, the authors hope to create a common language for doctors treating pelvic vein disorders. They are not claiming to have solved the problem for every woman, but they have provided a reliable, evidence-based map for navigating the treatment. The protocol offers a way to turn a complex, often frustrating condition into a manageable medical issue, giving patients a clear path from diagnosis to recovery.
