Treatment options

Evidence-based approaches to managing this condition.

First-line treatments

1

Disease management and monitoring

Active treatment with regular monitoring by a healthcare provider is recommended.

medication
2

Thoracic endovascular aortic repair (TEVAR)

Endovascular placement of a covered stent graft to exclude the thoracic aneurysm from blood flow. Preferred approach when anatomy is suitable due to lower perioperative mortality compared to open repair.

surgical
3

Serial imaging surveillance

Annual or biannual CT angiography or MRI to monitor aneurysm dimensions and assess for rapid growth or complications. More frequent imaging for larger aneurysms.

monitoring

Additional treatment options

Open descending thoracic aortic repair

Traditional open surgery replacing the diseased aortic segment with a synthetic tube graft. Reserved for patients with suitable anatomy not amenable to TEVAR or with connective tissue disorders.

surgical

Blood pressure strict control

Maintaining systolic blood pressure below 130mmHg through lifestyle modifications and antihypertensive medications to reduce aortic wall stress. Includes stress management and avoiding stimulants.

lifestyle

Angiotensin receptor blocker (ARB) therapy

Blood pressure medication that may provide additional benefit in slowing aortic dilation, particularly in patients with Marfan syndrome or other connective tissue disorders. Often combined with beta-blockers.
