What is Splanchnic VT?
Splanchnic vein thrombosis is a blood clot in the veins that drain the intestines and other abdominal organs. This includes the portal vein, mesenteric veins, and splenic vein. Because these veins drain the digestive tract, a clot can impair blood flow to the bowel and liver.
Common symptoms
- Abdominal pain, which may be severe and constant or intermittent
- Nausea, vomiting, or difficulty eating
- Abdominal bloating or distension
- Diarrhea or blood in the stool (if bowel is affected)
- Fever
- Fluid accumulation in the abdomen (ascites)
🚨 Seek emergency care immediately if you have:
- Severe, worsening abdominal pain — go to the emergency department
- Blood in your stool or vomiting blood
- Abdominal rigidity (board-like hard abdomen)
- Fever greater than 38.5°C
- Signs of jaundice (yellowing of skin or eyes)
Call 911 or go to the nearest Emergency Department.
Treatment
Anticoagulation is typically recommended for at least 3–6 months. Duration depends on the underlying cause, liver function, and bleeding risk. Regular monitoring is important.
