Complications of BAE. Of query number 3?

Patients History: Diagnosed with Pulmonary TB on August 2018, recovered in a year with ATT medicines. August 2020 dry cough noticed, tablets didn't help to stop cough. November end blood spotted in sputum. Dec first week 25ml/day noticed with cough. CT aortagram scan showed three cavities on right lung with blood from arteries, left lung normal. Underwent BAE on right lung, 3 bronchial arteries blocked, one left as connected to brain. After 36hrs patient died with massive hemoptysis in just 5 mins from outflow of blood from mouth and nose. My questions are 1) is massive hemoptysis expected so soon after BAE? 2) In hemoptysis, can blood come from mouth and nose as well? Patient just had a cough coming back from bathroom and blood started in no time leading to death 3) Patient had developed tieredness, sleepiness, right shoulder pain after 24hrs. Does this indicate any other Symptom? 4) Is it ok to walk after 24 hrs of BAE with above symptoms of query number 3?
