A doctor botched a routine procedure and killed a mother at her hospital appointment, according to a court.
Manchester Crown Court heard that Dr Isyaka Mman, 85, was responsible in a number of critical incidents leading up to the fatal appointment.
Mamman, who had admitted gross negligence manslaughter to medical watchdogs, was already fired by them for lying about his age, but was reemployed by the Royal Oldham Hospital.
His sentence is scheduled for Tuesday.
Shahida Parveen (mother-of-three), 48, went to hospital on September 3, 2018 with her husband, for possible myeloproliferative disorders investigations. A bone marrow biopsy was recommended, Andrew Thomas QC, the prosecutor, stated at the hearing.
Normally, bone marrow samples should be taken from the hip bone. However, Mamman of Cumberland Drive Royton, Oldham failed to get a sample on the first attempt.
He instead attempted to obtain a sample of Ms Parveen’s Sternum using a “highly risky” procedure – despite the objections of the patient and her husband. The court heard.
Mamman used the wrong biopsy needle and missed the bone. She pierced her Pericardium, which is the sac that contains the heart. This caused massive internal bleeding.
Ms. Parveen lost consciousness immediately after the needle was inserted. Later that day, she died.
Mamman was a Nigerian doctor who had been working in the UK since 1991. He was employed by Pennine Acute Hospitals NHS Trust from 2004 to the time of the fatal accident.
The court found that his age is “controversial” as his birthplace, rural Nigeria, did not have a system for birth registration.
Initially, he told the NHS that he was born 1941. Later, he claimed that he was actually born in 1947. This suggests that he began his degree program at 10.
He was found guilty by the General Medical Council of serious professional misconduct in 2004 and was suspended for one year for lying about being his age.
After he was reinstated to the GMC’s register, the trust fired him. However, he was reemployed in 2006 by the trust, who accepted his birth year as 1943.
Mamman, who had been fired from his previous job with the Medway Trust for “poor performance”, filed a formal complaint to the Oldham hospital in 2015. A patient complained that Mamman used excessive force during a bone marrow biopsy.
Another clinical incident occurred in the same year, involving a bone-marrow biopsy and an incorrectly inserted needle.
Although the patient survived, he was permanently disabled.
