Cause of death

Large intestinal infarction due to volvulus

AI-generated summary

Sharon Lee McDonald, a 47-year-old woman with Down syndrome, died from large intestinal infarction secondary to volvulus (twisting of bowel). She was admitted with presumed faecal loading causing bowel obstruction but developed sigmoid volvulus with haemorrhagic infarction. She had known megacolon requiring careful dietary management and regular laxatives. The coroner found no evidence of procedural injury from nasogastric intubation. The death resulted from a vascular catastrophe (complete bowel twist causing tissue death from lack of blood supply) in a patient with complex medical needs. Better recognition of volvulus risk in megacolon patients and potentially earlier imaging or surgical intervention might have prevented this outcome, though the acute nature of volvulus limits preventability.

FINDING:

THE CORONER: I find that the identity of the deceased was

Sharon Lee McDonald normally resident at 9 Reita Avenue, Wantirna South.

I am satisfied that Ms McDonald died of (1) A large intestinal infarction, 1(b) volvulus - to which a contributing factor was her Down Syndrome.

Ms McDonald was a 47 year old woman with Down Syndrome who died of complications of large intestinal infarction due to volvulus.

A review of the Eastern Health Angliss Hospital medical record reveals that she was admitted to that hospital on 6 October 2011 with bowel obstruction thought to be secondary to faecal loading.

She had ongoing problems with Megacolon which required a careful diet of minced food and regular use of Lacatose.

According to the Eastern Health Angliss Hospital records she was diagnosed with an arterial septal defect in 1990 at the Austin Hospital. There was no surgical intervention. She was in high level care and was mainly uncommunicative and was being looked after by several caregivers in the community.

Post-mortem examination revealed volvulus of the sigmoid and transverse colon with haemorrhagic infarction of the wall. Approximately 500 mls: of haemorrhagic fluid was found within the peritoneal cavity.

There was evidence of congenital heart disease with a patent arterial septal defect which measured three centimetres across. As a result, the right arterial

cavity was dilated and the right ventricle wall was

thickened. Histological examination of the lung showed early aspiration pneumonia. There was evidence of severe pulmonary hypertension. There was no post-mortem evidence of injury to the upper airway or gullet which may have been caused by the introduction of the nasogastric tube.

Volvulus is the complete twisting of the loop bowel around its mesenteric base and produces intestinal obstruction and infarction of the bowel dying off of tissue due to lack of blood supply.

This lesion occurs most often in large loops of the sigmoid but can happen elsewhere in the bowel as well.

There was no evidence of adhesions at post-mortem. Due to the marked distension and infarction of the bowel the possibility of malrotation of the bowel cannot entirely be excluded. Volvulus of the bowel is often complicated by shock and vascular collapse.

These are my findings.
