Vascular injury is suspected and assessed clinically through examination of the limb for the classic signs of arterial compromise, including pallor or mottled skin colour, coldness compared to the unaffected limb, absent or reduced pulse, progressive numbness or weakness, and severe pain out of proportion to the apparent injury. These findings indicate an emergency requiring immediate imaging and surgical intervention. Doppler ultrasound provides rapid bedside assessment of blood flow, and CT angiography gives detailed mapping of the vessel injury and helps plan the surgical approach. Any of these warning signs following an injury should prompt immediate emergency evaluation.

The technique used depends on the nature and extent of the vessel injury. Small lacerations or partial tears may be repaired directly by suturing the vessel wall. Larger defects that cannot be closed without narrowing the vessel are repaired using a patch of vein or synthetic material. Where a segment of vessel has been destroyed or is missing, an interposition graft using a length of vein harvested from elsewhere in the body bridges the gap and restores continuity. In complex cases performed under microscopic magnification, microvascular anastomosis reconnects very fine vessels with precision. Fascia release may also be performed alongside vascular repair to address compartment syndrome.

With timely and technically precise repair, blood flow through repaired vessels can be successfully restored in the majority of cases. The functional outcome depends on the extent of any associated tissue damage that occurred before or during the repair, the presence of associated nerve injuries, and how effectively any complications are managed in the post-operative period. Rehabilitation is an important component of recovery particularly when vascular injury is accompanied by nerve, bone, or soft tissue damage. Physiotherapy addresses functional deficits in the limb, working to restore strength, mobility, and coordination as the repaired and recovering tissues allow.

In many cases, successfully repaired blood vessels function well in the long term and the patient recovers normal or near-normal limb function. However, repaired vessels carry a small risk of developing narrowing or occlusion over time, and long-term surveillance using Doppler studies may be recommended to monitor their patency. Associated nerve injuries, which often accompany vascular trauma, can take many months to recover and may leave permanent partial deficits. At Galwa Care Hospital, long-term follow-up is offered to every vascular injury patient to monitor vessel function, nerve recovery, and overall limb health, with early intervention available if any problem is identified.
