Relatives of a woman who bled to death following an operation at a Sheffield hospital are taking legal action.
Louise Grant, of Ben Close, Loxley, went to the Northern General Hospital to have a benign cyst removed, but complications set in.
The 46-year-old mum-of-two suffered internal bleeding, described by a medic as ‘torrential’.
During her inquest, it emerged surgeons removed a third of Mrs Grant’s lung during the operation without consent.
Following the surgery, sutures used to tie off the vital pulmonary artery became displaced and Mrs Grant started bleeding to death internally, without anyone realising until it was too late.
A tube from a chest drain which could have highlighted the problem became kinked when she was moved from the operating table to a bed and little blood came out.
Mrs Grant then suffered a heart attack and it was 20 minutes before surgeons opened up her chest again to discover the bleeding.
Legal action is to be taken against the Sheffield Teaching Hospitals NHS Foundation Trust, which has denied liability.
Jenny Baker, of Sheffield law firm Irwin Mitchell, which is representing Mrs Grant’s husband, Shaun, said lessons need to be learned.
He said: “We hope the trust will continue to work with us so we can provide Louise’s family with the justice they deserve.
“The family just want answers as to how this could happen and reassurances lessons have been learned to prevent others from suffering the same fate.
“It is vital these issues are addressed so patient safety can be improved.”
Speaking after the inquest, Mr Grant said: “We are still absolutely devastated about losing Louise in such terrible circumstances and it’s something that we will never get over. I miss her every day.
“Our daughters Hanna and Eleanor have also lost the love and guidance that only a mum can provide.
“It also appears Louise could have been saved if surgeons had opted to quickly close the source of the bleed. Instead they decided to pointlessly pump litres of blood into Louise for 25 minutes, but wondered why her blood pressure remained flat?
“The inquest has given us some of the answers we were looking for about how and why she died.
“Although it won’t bring her back, we just want to know her death is not in vain and improvements will be made so other families don’t have to suffer as we have.”
