Obstetric fistula in Malawi: preparedness for prevention and management of obstetric fistula
Obstetric fistula remains a severe maternal morbidity in low-resource settings, reflecting persistent inequities in access to timely, safe obstetric care. This doctoral study examines Malawi's preparedness to prevent and manage obstetric fistula using a mixed-methods approach anchored in the …

Pathology of uremic vascular diseases: calciphylaxis and arteriovenous fistula
… most effective approach is through arteriovenous fistula (AVF). AVF connects an artery and vein to increase the blood flow needed for hemodialysis treatment. However, complications, such as stenosis of AVF portends a bad prognosis for patients. This study focuses on the microarchitecture of AVF to …

Pre-operative Risk Factors for Arteriovenous Fistula Failure in the Haemodialysis Population
The arteriovenous fistula (AVF) is a lifeline for patients requiring renal replacement therapy, allowing repeated access to the high blood flow needed for haemodialysis. However, failure rates for AVFs remain high, at around 30-40 % after one-year, typically occluding secondary to stenosis. Many …

Patient-specific computational haemodynamics in the arteriovenous fistula and aorta of a chronic kidney disease cohort
… and repeatable procedure. An arteriovenous fistula (AVF) is widely considered the ‘gold-standard’ vascular access. However, AVFs suffer from poor patency rates, and their non-maturation is a key issue in failing cases. Localised haemodynamics and flow patterns are hypothesised to be …
