Dr. Rishi Chadha, MD is a board‑certified gastroenterologist who specializes in preventive gastroenterology, colorectal cancer screening, and minimally invasive endoscopic procedures. He completed his fellowship at Sunrise Health GME in Las Vegas and previously trained in internal medicine at St. Vincent’s Medical Center in Connecticut.
Portal vein thrombosis (PVT) happens when a blood clot blocks the portal vein. This vein carries blood from your intestines to your liver. When it's blocked, blood flow slows or stops, which can raise pressure in nearby veins and cause liver damage.
Dr. Chadha reviews your symptoms, past liver health, family history of clots and any recent surgeries or infections.
He examines your abdomen for pain, swelling (ascites) or tenderness and checks for enlarged veins around the navel.
These assess clotting factors (INR, platelet count), liver function (ALT, AST, bilirubin) and screen for underlying blood disorders or infections.
