VASCULAR SURGERY
We have a team of dedicated vascular specialists to provide a range of comprehensive vascular procedures.
The common problems of the vascular system include:
| • |
Varicose veins |
| • |
Leg ulcers |
| • |
Gangrene of the feet |
| • |
Stroke (Usually from carotid artery narrowing) |
| • |
Aneurysms (abnormal enlargement of the artery) |
| • |
Claudication (calf cramps when walking) and rest
pain (pain from arterial blockage) |
Surgery for vascular problems can be divided into :-
Endovascular Techniques
Endovascular techniques are methods of treatment using
a puncture through the skin rather than large wounds.
Through a sheath inserted into the artery or vein, treatment
is effected. The endovascular techniques include radiofrequency
ablation of varicose veins, endovascular stenting of
aneurysm, angioplasty and stenting for arterial obstruction.
In balloon angioplasty, a balloon is used to open a
narrowed or blocked artery to improve circulation to
the feet. Sometimes, this is combined with placement
of a stent made of wire, to keep the affected artery
from narrowing back down. Radiofrequency ablation of
a varicose vein is a minimally invasive technique of
treatment that does not cause much bruising and discomfort,
thus allowing an early return to work or normal activities.
Open Methods
Open Methods would be lower limb bypass procedures
for arterial obstruction, abdominal aneurysm repairs
and carotid artery endarterectomy. In diabetic patients
or smokers with blocked arteries in the legs, balloon
angioplasty may not be enough to improve blood flow,
hence a bypass procedure using either the patients own
vein or a prosthetic tube to get around the blockage
is used. Carotid endarterectomy is a method of clearing
the fat deposits in the artery supplying blood to the
brain. This is done to prevent strokes.
