Professor Chang Guangqi: Aortic Aneurysm, Dissection, and Endovascular Specialist
Professor Chang Guangqi is a senior vascular surgeon, professor, doctoral supervisor, and chief of vascular surgery at the First Affiliated Hospital of Sun Yat-sen University in Guangzhou. His clinical and academic work focuses on aortic aneurysm and dissection, complex endovascular repair, aortic-arch branch reconstruction, carotid disease, peripheral arterial disease, venous thrombosis, and vascular graft infection.
Clinical and Academic Focus
- thoracic and abdominal aortic aneurysm;
- type B aortic dissection;
- complex endovascular aortic repair;
- aortic-arch branch reconstruction;
- carotid and peripheral arterial disease;
- deep-vein thrombosis and venous obstruction;
- vascular graft and stent-graft infection;
- open, endovascular, and hybrid vascular surgery; and
- second opinions before complex aortic treatment.
Aortic Aneurysms
An aortic aneurysm is abnormal enlargement of the body’s main artery. Many aneurysms cause no symptoms until they become large, expand rapidly, leak, or rupture.
Treatment depends on diameter, growth, symptoms, location, body size, anatomy, genetic disease, and surgical risk. Options include surveillance, open repair, endovascular repair, or a hybrid approach.
Type B Aortic Dissection
Type B dissection involves the descending aorta beyond the vessels supplying the head and arms. Uncomplicated cases may initially be managed with intensive blood-pressure and heart-rate control plus close imaging.
Endovascular or open treatment may be needed for rupture, organ malperfusion, persistent pain, uncontrolled hypertension, rapid enlargement, aneurysmal degeneration, or other high-risk features.
Endovascular Aortic Repair
Endovascular repair places a stent graft through an artery, usually in the groin, to exclude an aneurysm or seal a dissection entry tear. It avoids a large chest or abdominal incision but requires suitable anatomy and lifelong imaging.
Possible complications include endoleak, stent migration, branch-vessel obstruction, stroke, spinal-cord ischemia, kidney injury, and the need for reintervention.
Aortic-Arch Branch Reconstruction
When an aortic lesion involves arteries to the brain and arms, repair may require branch-vessel reconstruction, bypass, fenestration, branched devices, in-situ techniques, or a hybrid strategy.
Professor Chang has published work on in-situ laser fenestration during thoracic endovascular aortic repair. This is a specialized technique whose availability and suitability depend on anatomy, device choice, regulation, and center experience.
Carotid Artery Disease
Carotid narrowing can increase ischemic-stroke risk. Management may involve preventive medication, carotid endarterectomy, stenting, or surveillance.
The decision depends on symptoms, degree and character of stenosis, anatomy, age, health, and procedural risk. Sudden weakness, speech difficulty, or vision loss requires emergency stroke care.
Peripheral Arterial Disease
Peripheral arterial disease can cause exertional leg pain, non-healing wounds, rest pain, or threatened limb loss. Treatment includes risk-factor management, exercise, medicine, endovascular intervention, bypass surgery, and wound care.
Deep-Vein Thrombosis
Deep-vein thrombosis can cause swelling, pain, skin change, and pulmonary embolism. Anticoagulation is the main treatment for most patients, while selected extensive cases may need catheter-based clot removal or venous reconstruction.
Vascular Graft Infection
Infection of an aortic or peripheral vascular graft is serious and may cause fever, pain, bleeding, fistula, sepsis, or imaging abnormalities. Management can require prolonged antibiotics, drainage, graft removal, reconstruction, or a staged strategy.
Who May Consider a Consultation?
- patients with thoracic or abdominal aortic aneurysm;
- stable patients with type B aortic dissection;
- patients needing complex arch or branch-vessel reconstruction;
- patients comparing open, endovascular, and hybrid repair;
- patients with endoleak or enlargement after previous stent grafting;
- patients with carotid or peripheral arterial disease;
- patients with extensive venous thrombosis or obstruction; or
- patients with suspected vascular graft infection.
Medical Records to Prepare
- a precise symptom, diagnosis, and treatment timeline;
- contrast-enhanced CT angiography of the entire aorta in original DICOM format;
- arterial and venous ultrasound, MRA, and catheter angiography;
- all previous open and endovascular operative reports;
- graft, stent-graft, branch-device, and implant information;
- serial imaging showing vessel size and change over time;
- brain, kidney, intestinal, and limb-perfusion assessments;
- infection cultures and antimicrobial records when relevant;
- blood-pressure records and complete medication history; and
- a clear list of treatment and surveillance questions.
Planning an International Consultation
New severe chest, back, or abdominal pain, fainting, stroke symptoms, a cold painful limb, coughing or vomiting blood, or shock requires immediate local emergency care.
Stable patients should confirm whether complete imaging and previous device records can be reviewed. Remote medical-record review requires physician authorization. Final treatment eligibility and strategy require complete in-person vascular assessment.
How CMCS Can Assist
CMCS – China Medical Concierge Shanghai is an independent medical concierge and health management company, not a hospital. We assist international patients with organizing and translating vascular records, identifying an appropriate specialist, requesting appointment availability, arranging interpretation, and planning medical travel in China.
Access to Professor Chang, remote review, open surgery, endovascular repair, or a particular device is subject to doctor and hospital approval. CMCS does not guarantee appointments, procedure eligibility, device availability, or clinical outcomes.
