Thoracic Aortic Aneurysm Market Size, Share & Trends Analysis Report By Treatment (Open Surgical Repair (OSR), Thoracic Endovascular Aneurysm Repair (TEVAR)), By Product, By End Use, By Region, And Segment Forecasts, 2025 - 2033

Thoracic Aortic Aneurysm Market Summary

The global thoracic aortic aneurysm market size was estimated at USD 1.65 billion in 2024 and is projected to reach USD 5.04 billion by 2033, growing at a CAGR of 13.36% from 2025 to 2033. This growth is driven by the rising prevalence of hypertension and connective tissue disorders, an increasing aging population, and growing adoption of minimally invasive endovascular procedures.

Technological advancements in stent graft design, improved diagnostic imaging, and early disease detection contribute to market expansion. Supportive reimbursement policies and expanding awareness of thoracic aortic aneurysms among both physicians and patients are further accelerating treatment uptake globally.

The increasing prevalence of hypertension, smoking, and atherosclerosis, which are key risk factors for thoracic aortic aneurysm, is a major driver of market growth. As aging populations grow globally, the incidence of degenerative vascular conditions continues to rise, directly increasing the demand for diagnostic and therapeutic solutions. In March 2025, an article published in Biomedicines analyzed the relationship between atherosclerosis (AS) and aortic aneurysm (AA), including thoracic AA (TAA). It reported comorbidity rates ranging from 18% to 90%, influenced by aneurysm location, age, genetic background, and bicuspid aortic valves.

Technological advancements in endovascular aneurysm repair (TEVAR) have significantly boosted the market by offering minimally invasive alternatives to open surgery. These innovations have led to reduced hospital stays, lower procedural risks, and expanded treatment eligibility for high-risk patients. Device manufacturers are continually developing next-generation stent grafts with enhanced precision, flexibility, and durability, further accelerating their adoption among vascular surgeons worldwide. In May 2025, SHIP International Hospital in Dhaka performed a Thoracic Endovascular Aortic Repair (TEVAR) on a 57-year-old patient with a thoracic aortic aneurysm (TAA), a bulge in the chest portion of the aorta. Referred by a NICVD professor after being denied treatment elsewhere, the patient underwent the minimally invasive procedure with support from an endovascular stent graft vendor.

The growing use of advanced imaging modalities such as CT angiography, MRI, and ultrasound for early and accurate detection of thoracic aortic aneurysms is fueling market growth. National screening programs and increased awareness among both clinicians and patients are contributing to earlier diagnosis and timely intervention. In parallel, artificial intelligence tools and digital health platforms are being integrated into diagnostic pathways, supporting better risk stratification and patient monitoring.

In June 2025, an article published in Nature Communications discussed an AI model that enables opportunistic screening for thoracic aortic aneurysms (TAA) using routine breast MRI scans. The model improved detection rates by 3.5× compared to standard clinical reads. It flagged high-risk patients based on both aortic size and body-size-adjusted indices like AHI and ASI.
