K75.1

Clinical Causes: Infections originating from abdominal organs such as appendicitis, diverticulitis, or an infected biliary system Intra-abdominal abscesses or infections that spread to the portal vein Thrombophilic disorders, which increase the risk of blood clot formation Trauma or injury to the abdomen that damages blood vessels Cancer within abdominal organs that invade or compress the portal vein Use of certain medications or conditions that promote blood clotting

Key Symptoms: Fever and chills Abdominal pain, typically in the upper right quadrant or around the liver Tenderness in the abdomen General malaise or feeling unwell Nausea and vomiting Jaundice, which leads to yellowing of the skin and eyes in some cases Ascites, or fluid accumulation in the abdomen

Diagnosis Path: Blood tests to detect infection, inflammation, and blood clot markers Ultrasound imaging of the abdomen to visualize the portal vein and detect thrombus (clot) Contrast-enhanced computed tomography (CT) scan to assess the extent of inflammation and clot formation Magnetic resonance imaging (MRI) in some cases for detailed visualization Blood cultures if an infection source is suspected

Treatment Protocols: Intravenous antibiotics to treat underlying infection Anticoagulant medications to prevent clot extension and promote clot resolution Supportive care including pain management, hydration, and rest Surgical intervention in cases of abscess drainage or if the infection does not respond to medical therapy Monitoring through imaging to assess the response to treatment and the resolution of the thrombus
