Hello, Thanks for writing to Health Care Magic, I am Dr Muhammd Ahmad, I have closely read your question and I understand your concerns, I will hereby guide you regarding your health related problem. Aortic dissection can get to quite a dangerous situation if it s progressing continuously or if it is leaking. Indeed it s only cure is surgery can t be treated with medication and can get dangerous for life if left untreated. It involves opening the chest by vascular surgeon and repairing the torn part of the vessel ..usually the torn part is resected and then the normal ends of the remaining artery are joined together, if a big stump of artery has to be taken out then putting some vessel at it s place is considered but this is very rarely done. It s a major surgery which can lead to any outcome but usually doctors weigh benefits over risks.. and in case of a bad dissection.. benefits are always more in getting the surgery done. If done well, patient usually ends up getting saved. Yes it might take 2..3 months to get out of effects of surgery and with time a person can get back to near normal life. I hope this answered your question, if you have more feel free to ask. Regards. Dr.Muhammad Ahmad. General and Family Physician..
