Intracranial aneurysms (IAs), often referred to as cerebral aneurysms, represent localized balloon-like bulges within the walls of brain arteries. These aneurysms carry a serious threat because if they rupture, they can cause catastrophic hemorrhagic strokes, often with severe consequences. Many patients remain symptom-free for years, but the sudden rupture can lead to significant morbidity and mortality. Recent improvements in diagnostic methods and treatment strategies have contributed to a rapidly expanding Intracranial Aneurysms Market. This growth is driven by increasing neurological disorders, aging populations, and advances in less invasive therapies.
According to DelveInsight, the Intracranial Aneurysms Market Size is expected to witness robust growth due to a strong pipeline of innovative clinical products, technological advancements, and a deeper understanding of the underlying disease mechanisms.
Epidemiology Insights
Globally, 3-5% of people are estimated to have intracranial aneurysms, most commonly diagnosed in adults between 35 and 60 years, with a higher risk among females. The vast majority remain undetected until rupture, which causes nearly 85% of spontaneous subarachnoid hemorrhages (SAH). The incidence of rupture is estimated at 6-10 cases per 100,000 person-years.
DelveInsight’s epidemiological analysis across seven major markets (7MM) — including the US, five European countries, and Japan — shows a growing patient pool, thanks to better access to advanced diagnostic technologies and increased awareness. In the US, it’s estimated that over 6 million people harbor unruptured aneurysms, with about 30,000 annual ruptures.
Current Treatment Landscape
The primary goal in managing intracranial aneurysms is to prevent rupture or, in cases where rupture occurs, to minimize brain damage and complications. Treatment options include:
-
Surgical Clipping: A conventional but invasive approach involving open-brain surgery where a clip is placed around the aneurysm neck to halt blood flow.
-
Endovascular Coiling: A less invasive procedure where platinum coils are delivered via catheters to induce clotting inside the aneurysm. This technique has gained favor due to quicker recovery and fewer complications.
-
Flow Diversion Devices: A recent innovation, such as Medtronic’s Pipeline Embolization Device, uses stents to redirect blood flow away from the aneurysm, encouraging healing of the affected artery.
The Intracranial Aneurysms Treatment Market is rapidly evolving, driven by these emerging therapies that offer improved safety and efficacy.
Market Growth Factors
Several factors are fueling market expansion:
-
Increasing Risk Factors: Lifestyle factors like hypertension, smoking, alcohol use, along with genetic predispositions, have led to more aneurysm cases. Additionally, longer life spans mean more individuals develop these conditions over time.
-
Technological Innovation: Advances such as AI-enhanced imaging, robotic-assisted surgery, and 3D printed models for preoperative planning are transforming diagnosis and treatment.
-
Enhanced Screening and Awareness: Public health programs and improved access to healthcare are increasing early detection rates of unruptured aneurysms using non-invasive imaging techniques like MRI and CT angiography.
-
Robust Clinical Pipeline: Several promising new devices and therapies under clinical development aim to reduce aneurysm recurrence and improve long-term outcomes.
Challenges Limiting Market Growth
Despite progress, some obstacles remain:
-
Many aneurysms remain silent and go undiagnosed until rupture, particularly in regions with limited healthcare infrastructure and screening protocols.
-
The cost of surgical and endovascular interventions can be prohibitive in resource-limited settings.
-
Post-rupture therapeutic options are limited, with no breakthrough pharmacological treatments for vasospasm or ischemia prevention yet available.
Market Size and Outlook
DelveInsight’s comprehensive report indicates that the Intracranial Aneurysms Market Size was valued at USD XX billion in 2023 across the 7MM, with a projected compound annual growth rate (CAGR) of XX% through 2034. The United States leads the market due to advanced healthcare systems, high disease awareness, and supportive reimbursement frameworks favoring minimally invasive treatments.
Growth drivers include:
-
Expanding eligible patient populations
-
Adoption of next-generation devices
-
Increased volume of elective procedures for unruptured aneurysms
-
Accelerated product launches supported by a strong pipeline
