Chronic iliac vein insufficiency occurs when there is a partial or complete blockage in a major vessel that drains blood in the legs. Due to the increasing prevalence of this condition, vascular specialists use modern technology to provide symptomatic relief.
Nowadays, surgery plays an important role in the management of chronic venous insufficiency.
Venous stenting procedures include the placement of a metal mesh tube into the occluded veins of the lower extremities. It firmly stretches the diameter of the wall to promote smooth blood flow into the vessels.
As a result, it reverses the narrowing of a specific portion of the vessel to increase oxygen transport into the tissues. A vascular specialist uses ultrasound to visualize if the stent inserts into the right vein. Visualization on the ultrasound screen also confirms that the affected vein is open.
In severe cases of iliac vein insufficiency, a surgical bypass is often the final treatment option. This procedure involves transplant of a healthy vein in the body to circumvent the occluded portion of the vein. It is a major surgical operation performed under general anesthesia.
Due to the complexity of the procedure, an anatomical bypass is a last resort in cases that are refractory to other medical and surgical techniques.
Doctors usually recommend debridement when extensive skin damage has occurred due to severely occluded veins in the leg. It involves removal of dead tissue and debris that have accumulated due to the worsening obstruction in the underlying vessel.
A specialist performs this when a deep ulceration or excavation is already present in the leg; and also recommended in cases of infection wherein fever, wound discharge, and elevated white blood cell counts may be present.
Surgical treatment of chronic venous insufficiency improves recovery and decreases complication rates upon treatment. Thus, it is crucial to visit a vascular specialist who can perform a modern approach to the treatment of iliac vein obstructions.
