What Improves the Survival Rate When an Aneurysm Ruptures?


Quick Answer

A ruptured aneurysm is a serious and often fatal medical emergency, but accurate and early diagnosis can improve survival rates, according to the Brain Aneurysm Foundation. Medical advancements, such as less invasive endovascular repair procedures, may lower mortality rates as well, says the National Library of Medicine.

Accurate diagnosis is critical when an aneurysm ruptures. About 25 percent of ruptured brain aneurysms are misdiagnosed, states the Brain Aneurysm Foundation. Misdiagnosis is even more frequent with ruptured abdominal aortic aneurysms, explains the Post Graduate Medical Journal. Available technology and imaging tools should be utilized to improve the time and accuracy of diagnosis and treatment, which will improve survival rates.

Multiple studies examine the effects of endovascular procedures on patient mortality rates in comparison to open graft replacement techniques. The benefits and cost-effectiveness of endovascular repair may slightly increase survival rates in patients with confirmed ruptures, but the two procedures consistently result in very similar outcomes according to one study, states the BMJ.

Other research shows more promise for the use of endovascular repair. Introducing endovascular repair as an alternative to open graft replacement resulted in a 27.1 percent decrease in the 90-day overall mortality rate for aneurysm treatment, according to the National Library of Medicine. When doctors provide treatment using the method that is best for the patient, survival rates improve for both endovascular and open repair operations, especially in patients over the age of 75.
