An Exploratory Study on the Application of Transarterial CT Angiography in the Interventional Treatment of Massive Hemoptysis

This is a single-arm, exploratory study to evaluate the value of transarterial CT angiography applying Nexaris Angio-CT in the interventional treatment of massive hemoptysis

Inclusion Criteria:

• Patients with massive hemoptysis（defined as more than 100mL per session or more than 300mL/day or with acute respiratory failure requiring mechanical ventilation or hemodynamic instability (systolic blood pressure < 90 mmHg), regardless of hemoptysis amount）

Exclusion Criteria:

• Pregnancy
• Patients with a previous history of bronchial artery embolization
• Uncorrectable severe infection, coagulation dysfunction, organ failure or cachexia, severe contrast agent allergy, and other interventional treatment contraindications
