Objective  To summarize the research status of percutaneous ultrasound interventional therapy for the patients with hepatic echinococcosis, and to provide some experience and reference for the treatment of disease in clinical medical personnel. Method  The relevant literature on percutaneous ultrasound intervention therapy for hepatic echinococcosis both domestically and internationally was summarized and analyzed. Results  For the patients with hepatic cystic echinococcosis (HCE), ultrasound-guided percutaneous transhepatic drainage is safe and effective for the World Health Organization Informal Working Group classification CE1 and CE3a cysts. For the patients with hepatic alveolar chinococcosis (HAE), although radical resection is still the gold standard, ultrasound-guided microwave ablation had better postoperative recovery and less trauma for patients with lesion diameter <5 cm; Due to limited research on the efficacy and safety of ultrasound-guided radiofrequency ablation for patients with HAE, further exploration is needed; Ultrasound guided percutaneous cyst puncture drainage is used for external drainage of necrotic material in the cyst cavity, which can effectively control infection and remove necrotic tissue; percutaneous transhepatic cholangial drainage (PTCD) could effectively relieve biliary obstruction, improve liver function, and enhance the quality of life of patients with advanced HAE complicated with obstructive jaundice. Conclusions  Ultrasound-guided percutaneous interventional techniques have their own advantages and disadvantages in treatment of hepatic echinococcosis. For patients with HCE, strict indications and contraindications should be followed when performing percutaneous ultrasound interventions. For patients with HAE, early-stage small lesions should be prioritized for microwave ablation, and patients in the middle and late stages with larger lesions or those with intra-cyst infection or jaundice should be treated with percutaneous cyst puncture drainage and PTCD to alleviate symptoms, following the second stage operation.
