If there is involvement of only the superficial veins then the complications are rare. However if the deep veins are involved the complications may be life threatening or cause serious distress to the patient.
Here a part of the clot breaks and dislodges to the lungs blocking its main blood supply with the result there can be no exchange of oxygen which is vital for the survival of the brain and tissues of all organs. It is a life threatening emergency needing urgent management.
This is a life long problem which follows long standing DVT and causes severe distress to the patient due to the permanent incompetence of the damaged venous valves. It mostly occurs months to years after DVT.
It causes disabling pain, swelling and heaviness in the affected leg. There is not much cure of this distressing condition and there is no surgical intervention possible till now.
The valves are permanently damaged in the deep veins due to DVT leading to their incompetence which means blood cannot move against gravity when we are standing. This leads to severe swelling responsible for distressing pain, discolouration of the ankles and finally ulcers. Much research is being done all over the world for valve replacement but the results are poor and failure rate high.
