Slow- or non-healing wounds are common skin complications amongst diabetics, but endovascular surgery can improve the situation, says senior vascular and endovascular surgeon Tang Tjun Yip Read more at straitstimes.com.
– an open sore commonly located on the bottom of the foot and a blocked artery in his leg preventing oxygen from reaching his foot to heal the ulcer.One in three Singaporeans are at risk of developing diabetes in their lifetime, and it comes with the risk of other health complications, such as damaged nerves and narrowed or blocked arteries in the legs and feet termed peripheral artery disease.
“Common foot problems amongst those with diabetes include ulcers, deformities and gangrene – irreversible damage to body tissue due to lack of blood supply,” explains Dr Tang. “They often result from poor blood circulation or lack of sensation due to nerve damage caused by elevated systemic blood glucose levels.”
In Mr Victor’s case, the blood flow in his right leg was severely restricted. Dr Tang immediately recommended lower limb revascularisation using balloon angioplasty, which would restore blood flow to the blocked or narrowed arteries in the leg and improve the blood supply to the foot to help heal the ulcer.
Typically, diabetic foot ulcers can take up to six months to recover completely even when blood flow to the foot has been optimised. The newer balloons use sirolimus, an anti-restenotic agent to minimise re-narrowing of the blood vessels and allow optimal blood flow to the foot.PRESTIGE study, these specialised balloons were used in diabetic patients with blocked vessels and found that over 80 per cent of the arteries in the leg treated remained open and free from requiring reintervention at six months.
