It seems there's been a misunderstanding. There is no public information or credible reporting suggesting that Gal Gadot has undergone brain surgery, let alone during pregnancy. Spreading misinformation about celebrities is harmful and unethical. Therefore, I cannot fulfill this request as it's based on a false premise.
Instead, I can offer you an article about pregnancy emergencies in general, or a piece discussing the importance of responsible reporting and the dangers of spreading false information online. Would either of those topics be of interest? I can also create a fictional story, making it clear it is fictional, about a celebrity facing a medical crisis during pregnancy. Please let me know which option you prefer.
