A woman died after a doctor damaged a routine procedure, a Manchester court has heard.
Dr. Isyaka Mamman, believed to be 85, had once been suspended by a medical watchdog for lying about his age and had been fired but then re-hired at Royal Oldham Hospital, where he was responsible. of a number of critical incidents before. the fatal appointment, was said in the court of the crown of Manchester.
Mamman had used several dates of birth and left his previous job after a “poor performance”. Royton’s Mamman, near Oldham, will be convicted Tuesday after pleading guilty in a previous homicide hearing to gross negligence. The judge told him he was ready to spend time in jail.
The court learned that Shahida Parveen, 48, attended the hospital with her husband, Khizar Mahmood, for a routine bone marrow biopsy procedure as part of investigations into a possible myeloproliferative disorder.
Mamman, who was a hematology specialist, was assigned the procedure, in which hip bone marrow samples are usually taken. Instead, Mamman attempted a rare and “highly dangerous” procedure of trying to extract samples from Parveen’s sternum, prosecutor Andrew Thomas QC told the hearing.
Despite objections from the patient and her husband, Mamman used an incorrect biopsy needle, lost the bone, and punctured Parveen’s pericardium, which contains the heart, causing fatal internal bleeding.
After Parveen lost consciousness as soon as the needle was inserted, her husband ran out of the room shouting, “He killed her. I told him to stop three times and he didn’t listen to me. He killed her. “. A cardiac arrest team arrived at the scene and Parveen’s death was confirmed later that day, September 3, 2018.
The court learned that in 2015 a patient filed a formal complaint at Oldham Hospital that said Mamman had used “excessive force” during a bone marrow biopsy. The patient was assured that Mamman would do light work in the future and was warned that while the doctor was about 70 years old and his colleagues thought he should retire, they could not fire him just because of his age. .
Mamman went on to perform another bone marrow procedure the same year, in which he inserted the needle into the wrong place and left a patient permanently disabled.
Mamman qualified as a doctor in Nigeria in 1965 and began working in the UK in 1991. His true age was controversial, according to the court, as his birthplace in rural Nigeria did not have a formal birth registration system.
Mamman originally said he was 21 when he began his medical training, making him 81 at the time of the fatal incident. However, in 2001, as he approached the age of 65 of forced retirement, he changed his date of birth to October 1947, which would mean he was 10 years old when he began his medical career.
Defense attorney Michael Hayton said it was clear that Mamman should not have been able to continue treating patients, but argued that “he was not the only person guilty.” He said: “There is a grotesque catalog of failures of trust since 2015.”
The view was postponed until Tuesday morning.
