Last year, Hayley underwent a craniectomy following an on-stage dance performance, and Derek had to update fans with what was going on. Now that Hayley is pregnant with the couple's first child, see how her health is doing now. What Happened to Derek Hough's Wife Hayley Erbert? On December 7, 2023, Derek announced via Instagram that his wife had suffered a cranial hematoma and was rushed to the hospital amid their dance tour. "At the end of last night's tout performance in Washington, D.C., my wife Hayley became disoriented and was taken to the hospital," the choreographer captioned his post. "She was diagnosed with a cranial hematoma from a burst blood vessel and required an emergency craniectomy. She is in stable condition. I want to thank the first responders and medical personnel who have cared for and continue to care for her. I ask for your prayers and positivity during this time."

While many sent their best wishes by commenting on Derek's post, fitness trainer Meghan Tieff provided further insight into the moments leading up to Haley's hospitalization. "I was in D.C. last night. The show was absolutely amazing," she commented via Instagram, adding, "Hayley was fabulous ... I am so sorry this happened. We were sad to not see her at the end of the show. I had a feeling something happened. Many prayers and sending love." MediaPunch/Shutterstock What Is a Cranial Hematoma? The full medical term - intracranial hematoma - is a life-threatening condition that occurs when the skull collects with blood. This arises from either a burst blood vessel or from a traumatic injury, such as a fall. As the blood collects inside the skull, it may spread through brain tissue and press down onto the brain, according to Mayo Clinic. Treatment for the condition varies, according to the health website. The patient should be monitored for any neurological changes over time and undergo CT scans to check on their progress. Surgery is based on the type of hematoma the patient is suffering from. If the collection of blood is located in one portion of the head and has "changed from a solid clot to a liquid," a surgeon may have to drain the liquid by drilling a hole into the skull. If the hematoma is large, a more substantial section of the patient's skull may have to be opened in order to remove the blood. It could take up to three months for a patient to recover following the invasive surgery. Depending on how the patient is feeling, one might require occupational and physical therapy. How Is Hayley Erbert Feeling Today? Per Derek's Instagram statement, Hayley was in "stable condition" after her surgery. Shortly thereafter, he took to social media to provide fans with an update. "Hayley has always inspired me with her will, her strength, and her resilience and no more so than in the last 48 hrs," he wrote in a statement. "She is now on the long road of recovery. Words cannot express how grateful and thankful we are for the support and love that you have given us. The kindness that we've been shown in this incredibly unfathomable, and life changing time is immeasurable."

"The offers of assistance that have poured in have been so humbling and appreciated. Our hope is that as a family, we can somehow and someway pay it forward," he wrote. A week later, the dance pro shared a first video of Hayley, along with an update, as the duo took a walk at the Washington monument. In the clip, Derek steadied his wife with his arm, with both bundling up in warm coats and Hayley wearing a protective helmet. "As you all know, the past week has been a challenging journey for us due to a life-threatening event that suddenly came into our lives," he captioned the emotional post in part. "It was a time filled with uncertainty and fear, going from living our dreams onstage, to a nightmare in an instant. But today, we are filled with hope and relief as we share with you an update. Hayley is doing well." View this post on Instagram A post shared by Derek Hough (@derekhough) Derek elaborated that his wife would be having another surgery. "Her recovery process has been nothing short of a miracle," he shared. "She still has a ways to go with another surgery, hopefully in a few weeks, to insert a skull implant to replace the piece that was removed during the craniectomy. It will restore the skull to its natural shape and protect the brain from injury." He concluded the post with gratitude for her medical care and support from the community.
