thrombus is either at the entry of the renal vein or within the inferior vena cava (IVC) < 2 cm from the confluence of the renal vein and the IVC. Level II: Thrombus extends within the IVC > 2 cm above the confluence of the renal vein and IVC but still remains below the hepatic veins. Level III: Thrombus involves the intrahepatic IVC. The size of the thrombus ranges from a narrow tail that extends into the IVC to one that fills the lumen and enlarges the IVC.
What are three main types of rockets that power modern spacecrafts? The three kinds of rockets are solid fuel rockets, liquid fuel rockets, and ion powered rockets. Edit
