Work on the major arteries and veins of the limbs: repairing them after injury, routing blood around a blockage, creating access for dialysis, and covering vessels that have become exposed. Restoring blood flow and rebuilding the tissue around it are usually both needed, and here they are done by one team.
Muscle begins to die after roughly six hours without blood supply. Arterial injury is treated as an emergency, not as an urgent case for the morning list.
The patient's own vein resists infection and stays open better than synthetic material in limb arteries, so it is used wherever one is available.
An exposed vessel or graft will eventually bleed. Soft tissue cover is planned in the same operation rather than referred on afterwards.
Dialysis fistulas are made as low in the arm as the vessels allow, keeping the vessels above available for the next one.
Vascular trauma is time critical and often arrives at night. Planned reconstruction, bypass and dialysis access are worked up with imaging and done to a list. The techniques overlap; the urgency does not.
The order is deliberate. Restoring flow before reconstructing tissue, and assessing the whole patient before operating on the leg.
Is the limb viable, is the patient stable, and is there an arterial injury. Pulses, Doppler and imaging where time allows.
Control bleeding, clear clot, trim to healthy vessel and repair directly or bridge with vein. Compartments are usually released at the same time.
Bone stabilised, nerve repaired or marked, and the repair buried under healthy tissue so it cannot dry out or become infected.
Circulation checked repeatedly. Fasciotomy wounds closed or grafted in stages. Dead muscle removed. Physiotherapy started early.
Graft surveillance scanning, medication, and secondary procedures for stiffness, tendon transfer or scar release once the limb has settled.
Restoring circulation to a limb nobody will then cover is half an operation.
The commonest failure in limb salvage is not technical. It is a gap between services: a vessel repaired by one team and a wound nobody will close, or a graft covered by a surgeon who cannot assess whether the vessel underneath is still worth keeping. Having vascular repair, microsurgery and soft tissue reconstruction in one place removes that gap.
Microsurgical training matters here beyond free flaps. It is what makes small calibre vein grafting, distal bypass and difficult dialysis access practical rather than theoretical. Emergency theatre access is what makes any of it possible within the hours that decide whether a limb survives.
Emergency vascular trauma, bypass for critical limb ischaemia and dialysis access are commonly covered by health insurance and by government schemes including PM JAY. Cost depends on the length of admission, graft material and whether further reconstruction is needed. Emergency treatment is never delayed for a financial discussion.
Ask for an estimate →Most of these are asked by families in the first hours after an injury.
Ask your question →Around six hours of warm ischaemia is the figure usually quoted, because that is when muscle begins to die irreversibly. It is not an absolute cut off. Cooling buys time, and a crush injury can do badly after less while a clean division can do well after more.
The patient's own vein is the best conduit available for limb arteries. It stays open better than a synthetic tube and resists infection far better in a wound that is usually contaminated. The donor leg manages without it, because the deep veins carry most of the return.
Because a limb that survives but is numb, stiff and painful can leave someone less able than a good below knee amputation with a prosthesis. Where that is a genuine possibility it is discussed openly rather than discovered after a year of failed operations.
When blood returns to muscle that has been starved, it swells inside its tight fascial compartments and can cut off its own circulation again. Releasing those compartments prevents a second catastrophe. The wounds are closed or grafted later.
A new fistula takes six to twelve weeks to mature. The vein has to enlarge and thicken under arterial pressure before it can be needled three times a week. Using it too early is the commonest avoidable way to lose one.
Emergency vascular trauma and bypass for a threatened limb are commonly covered by health insurance and by government schemes including PM JAY. Treatment is never delayed for a financial discussion; the paperwork follows.
