Disease Introduction
Major vascular diseases, including aortic dissection and aortic aneurysm, are critical conditions involving tearing or bulging of the aortic wall. Typical symptoms include sudden, sharp, stabbing chest, back, or abdominal pain. Rupture of these conditions carries an extremely high mortality rate and often requires emergency treatment. The general principle of treatment is to control blood pressure and heart rate as quickly as possible, selecting minimally invasive endovascular repair (EVAR/TEVAR), fenestrated branch stenting, or open surgery based on the lesion type and location, with close imaging follow-up.
Cutting-edge high-precision diagnostic and treatment technologies
- Domestic Multi-branch Stent : The G-Branch Thoracoabdominal Aortic Hybrid Multi-branch Stent System, jointly developed by Professor Guo Wei of the PLA General Hospital and Lifetech Scientific, has been approved by the NMPA. It is the world's first hybrid multi-branch system specifically designed for thoracic and abdominal aortic aneurysms.
- Thoracoabdominal aortic stent approved : In November 2025, the National Medical Products Administration approved Lifetech Scientific’s innovative thoracic and abdominal aortic endovascular stent graft system for endovascular repair of thoracic and abdominal aortic aneurysms.
- Intraoperative stenting for type A aortic dissection : In April 2025, the NMPA approved an integrated intraoperative stenting system for artificial blood vessels, used for ascending aortic and aortic arch replacement and descending aortic stenting in Stanford type A aortic dissection. The integrated distal sutureless fixation can shorten circulation time and reduce complications.
- Branched intraoperative stent : In November 2025, the NMPA approved an innovative product for branched intraoperative aortic stent systems, which are used for aortic dissection or aneurysm arch branch reconstruction.
- Minimally Invasive Reconstruction of Visceral Branches : In December 2025, Shanghai Renji Hospital used the domestically produced internal iliac branch stent intracorporeal octopus technique to reconstruct four visceral branch vessels in one procedure for patients with complex thoracic and abdominal aortic aneurysms, breaking through the traditional taboo of endovascular treatment.
