A Unique Presentation of Spontaneous Umbilical Hernia Rupture in Budd–Chiari Syndrome: Case Report and Review of Published Cases
This case report describes the first documented instance of an adult with Budd-Chiari syndrome presenting with Flood syndrome (spontaneous umbilical hernia rupture), demonstrating that this life-threatening complication can arise from non-cirrhotic, post-sinusoidal portal hypertension and can be successfully managed conservatively through multidisciplinary care.

In the human body, the liver acts as a vital processing plant, filtering blood and removing toxins. When this organ is damaged, it can struggle to let blood flow through it smoothly. This blockage causes pressure to build up in the veins that feed the liver, a condition known as portal hypertension. As this pressure rises, fluid begins to leak out of the blood vessels and into the belly, creating a swelling called ascites. Over time, this fluid can become so tense and heavy that it pushes against the front wall of the abdomen. The belly button, which is naturally a weaker spot where the muscles meet, can bulge outward under this constant pressure, forming a hernia. If the skin over this bulge becomes too thin and stretched, it can tear open, allowing the fluid to leak out of the body. This dramatic event is known as Flood syndrome. While it is a well-known complication for people with advanced liver scarring, or cirrhosis, doctors have long wondered if it could happen in other situations where the liver is not scarred but the blood flow is still blocked.
A team of researchers from India and Lebanon recently documented a rare instance of this phenomenon in a 39-year-old woman who did not have cirrhosis. Instead, her condition was caused by Budd-Chiari syndrome, a disorder where the veins that drain blood away from the liver become blocked by blood clots. This blockage creates the same high pressure and fluid buildup seen in cirrhosis, but the root cause is different. The woman arrived at the hospital with a history of abdominal swelling and a painful, darkened bulge at her belly button. She had been diagnosed with Budd-Chiari syndrome six months earlier but had not been taking her medication consistently. Just two days before her emergency visit, she had undergone a procedure to drain some of the fluid from her belly. Shortly after, she experienced a sudden rupture at her belly button, with fluid leaking out and then stopping.
Upon examining the patient, the medical team found her abdomen was swollen with fluid, and her belly button had a visible hole where the skin had broken open. The fluid that had leaked was clear and sterile, indicating it was simply the accumulated belly fluid and not an infection from the intestines. To understand exactly what was happening inside, the doctors used ultrasound and a specialized CT scan. These images revealed that the veins draining her liver were completely blocked, confirming the Budd-Chiari diagnosis. The scans also showed that the pressure from this blockage had caused the fluid to build up and weaken the skin around her belly button until it gave way. The team also noted that she had an underactive thyroid and moderately elevated homocysteine levels, which likely contributed to the formation of the initial clots.
The medical team faced a difficult decision on how to treat her. Usually, when a hernia ruptures and leaks fluid, surgeons rush to close the hole. However, operating on a patient with such high pressure in the abdomen and a blood clotting disorder carries a very high risk of failure or death. The doctors decided to try a conservative approach first. They treated the underlying cause by giving her medication to thin the blood and prevent new clots, while also using diuretics and albumin to help her body get rid of the excess fluid. They cleaned the wound carefully and watched her closely for any signs of infection. Remarkably, the leakage stopped on its own, and the wound began to heal without immediate surgery. The patient remained stable, and her condition improved significantly over the next month.
This case is significant because it shows that Flood syndrome is not exclusive to patients with liver scarring. It can occur whenever the pressure in the liver's blood vessels gets too high, regardless of whether the liver tissue itself is scarred. The researchers found that the mechanical forces required to cause this rupture—high pressure, a weakened abdominal wall, and a pre-existing bulge—can be driven by blood flow blockages just as effectively as by liver disease. By successfully managing the patient without emergency surgery, the team demonstrated that careful medical treatment can sometimes stabilize these critical situations. This adds a new chapter to the understanding of how liver-related complications can manifest, reminding doctors to look beyond the most common causes when they see these specific symptoms. The patient was eventually referred for a planned, elective repair of the hernia once her condition was fully stabilized, highlighting a path forward for managing such rare and dangerous events.
