To it may Concern: April 14, 2021 We are writing this letter to explain the adverse event that happened to my wife. I feel it important to inform you of this event in order to prevent this event from happing to others. We feel your form is not user friendly and does not lend itself to the reporting a COVID Vaccination event. It does not address reporting both dose information and does not provide sufficient space to describe a complicated event. I will attempt to fill in the items that were left blank as follows: Patient and My Thoughts:  We believe my vascular occlusion was caused by my Phizer vaccination, the time line and other problems of blood clots caused by other manufactures led me to believe so. When in the hospital some doctors thought it might be true, and many of my medical friends also agree with me. I am in the process of making an appointment with a hematologist, and hope that he may have insight to my blood clot problem. I feel you should investigate my event in order to save others, I am lucky to survive this event and do not know what future issues lay ahead for me. Regards:  Patient Time Line of Events Vascular Occlusion April 1, 2021  February 13-First Dose Coivd 19 Vaccination Phizer EC9269 at County Clinic Site  March 3 -Second Dose Covid 19 Vaccination Phizer EN6198 at County Clinic Site  March 11- Pedicure-Complained that it hurt, later that evening had pain in right hip and down leg to calf, pain became progressivity worse.  March 20- Pain in the right leg. Went to walk in Clinic, advised doctor of past pulmonary embolism. Because it was Saturday, they were unable to x ray, suggested we go to emergency. At the emergency we asked the doctor if there was a possibility of a blood clot. His reply was no, a very small percentage chance, less than 1% chance because of taking Elquis. The doctor stated he could order a ultura sound test for blood clots, but it would be a waste of time and money to do so but he could do so if we wanted. We requested he do the test, we wanted to know that there were no clots present. After the test, the doctor stated I told you so, no clots present. A cat scan was made, herniated disk present, a condition we knew was present. The problem was diagnosed as scintica nerve issue. Was given a shot for pain, prescription for steroids and Lidocaine patch written. Discharged with instructions for treatment. When at home the pain continued and progressively became worse, decided that I needed to return to the emergency site.  March 29- Returned to emergency. Doctor suspected that I had a herniated disc (sciatica) after hearing all my systems. The doctor stated the only way that he could be certain of his suspicions would be to have a MRI, I elected not to have it done today. The doctor encouraged me to follow up with my primary care physician (I did not have one) for further treatment. Also suggested that I could make an appointment for pain management. I made a appointment Internal Medicine for April 1st. Prescriptions written for acetaminophen, cyelobenzaprine, naproxen, discharge instructions given and discharged.  April 1st-In the morning, preparing for my appointment with internal group at 11am, after my shower, I could not walk on my left leg, I felt the pain was at a 10 level. like my leg was in a vise, the pain was higher than 10 if possible, maybe a 30, then I told my husband that he should call 911. My husband was like a deer in a head light, very confused, I had to tell two additional times before he did so. The 911 Fire Truck arrived in approximately ten minutes, ambulance shortly after. I was transported to the emergency facility. Upon arrival the doctor examined me and felt that I might have an aneurysm. Meds were given, I was then transported by ambulance, right light and siren to the Hospital Emergency, the nurse from the emergency facility traveled with me.  Upon arrival I was examined immediately and was given a CT Angiography, and it was determined that I had vascular occlusion with a white foot. Dr., a Vascular Surgeon told me that I needed immediate surgery to remove extensive intraluminal thrombus in the thoracic, proximal abdominal aorta as well as in the bilateral profunda femoris artery, as well as the femoral arteries, superficial femoral arteries, popliteal arteries with single vessel runoff present to the right ankle and no definite flow identified in the left runoff vessel. After a 4 Hr. surgery and recovery I was transferred to the CCU unit staying there for two days, transfer to a normal room and discharged on April 4th. My care throughout stay and treatment was excellent, beyond my expeditions, the staff and doctors are great! Hospital is exceptional.  Additional Thoughts of Husband- My wife has been very healthy throughout our marriage of 57 years. The discovery of Brest Cancer in 2018, successfully treated, and her Pulmonary Embolism in 2019 and near-death experience also successfully treated as an eye opener to me. When the events of April 1st happened, I was overwhelmed, what is going on, I thought wife's sciatica diagnosis could be causing pain, but not to the extent to call 911, maybe I should take her back to Emergency. Thank God she was correct in telling me to call 911. The issue I have is why did she have Vascular Occlusion? Blood clots can not happen when taking Eliquis, I have been told that by Medical friends in addition to physicians. All of these opinions have ruled out blood clots in my mind and could have caused me to be responsible for my wife's death, thank God again.  I wonder if the COVID-19 Vaccination could be a cause. I have searched this thought and found many articles stating blood clots a side effect with people with Covid. Also there have been blood clot side effects with vaccinations such as in AstraZeneca. My fear is will blood clots return. I wonder will we ever know what caused wife's issue. I would encourage physicians not to discount the possibility of blood clots being present no matter what medicine is being taken. I feel we were in the right place when this event happened, thank God that were. The Doctors, Nurses at the hospital have saved my wife's life, and I am grateful for their care.
