Closed injury of abdominal parenchymal organs is a common clinical acute abdomen, early correct diagnosis and timely and reasonable treatment is the key to reduce the mortality of trauma. For the patients with trauma, contrast-enhanced ultrasound can clearly show the size, shape, range and location of active bleeding, so the extent and degree of organ injury can be diagnosed correctly and timely in the early stage. For the patients with grade III and IV trauma but hemodynamic stability, and grade III with active bleeding, Ultrasound guided percutaneous thrombin injection can achieve better therapeutic effect. The value of contrast-enhanced ultrasound in the diagnosis of abdominal organ injury and the value of interventional ultrasound in the treatment of abdominal organ injury are reviewed in this article, objective to investigate the value of ultrasonography in diagnosis and treatment of closed injury of abdominal parenchymal organs.
