Intracranial Aneurysm Market Overview

According to fortune business insights, the global intracranial aneurysm market size was valued at USD 1.74 billion in 2025 and is projected to grow from USD 1.87 billion in 2026 to USD 2.95 billion by 2034, exhibiting a CAGR of 5.90% during the forecast period. North America dominated the market with a share of 43.70% in 2025.

An intracranial aneurysm is a balloon-like growth in a blood vessel wall. Ruptures can cause life-threatening bleeding. Treatment focuses on preventing future ruptures through methods like microsurgical clipping, endovascular coiling, and flow diversion. The market is driven by increasing awareness, a rising number of patients with cerebrovascular diseases, and active R&D by market players to introduce novel treatment devices. According to the Brain Aneurysm Foundation, an estimated 6.7 million people in the U.S. have an unruptured brain aneurysm. The COVID-19 pandemic negatively impacted the market by causing a decline in procedural volumes.

Latest Trends

Growing Preference Toward Minimal Invasive Procedures and Technological Advancement

There is a significant shift in patient preference from traditional open surgery (craniotomy) to minimally invasive procedures like coiling and stenting. These modern techniques, which include flow diverters, divert blood flow away from the aneurysm without opening the skull, resulting in reduced physical trauma and faster recovery times. The positive outcomes and safety profile of these novel devices are encouraging market players to introduce more technologically advanced products.

Drivers & Restraints

Increasing Prevalence of Cerebral Aneurysm to Augment Market Growth

A key driver for the market is the rising prevalence of cerebral aneurysms globally. Advances in imaging techniques like 3-D angiography are leading to more timely diagnoses, increasing the patient population seeking treatment. The positive clinical outcomes of devices used in minimally invasive procedures, such as coils and flow diverters, are further expected to drive market growth.
