<s>[INST] Mother-Inlaw and .7 aneurysm two years ago. She had a stent put in and now she had a MRI and it showed that the stent is leaking and its up to a .78cm. She does not have the lung strength to do surgery due to heavy smoking. Lung capacity 25 percent. Approximately how long does she have to live and how large can it grow? Stent was put into her abdomen. [/INST] Thanks for your question on Chat Doctor. I can understand your mother in laws situation and problem. Aneurysm leak if not treated surgically can be life-threatening. Patient slowly develops hypotension and then cardiac arrest. Her lung condition is not allowing surgery, but you need to take risk of surgery because without surgery she will definitely die within 2-3 months. But if surgery is successful, she can be easily live for 5-6 years. So discuss risk benefit ratio with surgeon and plan accordingly. Hope I have solved your query. Wishing good health to your mother-in-law. Thanks. </s>
