STENTING FOR ILIAC VEIN COMPRESSION FOR MAY-THURNER SYNDROME (PREAUTHORIZATION REQUIRED)

III.196 STENTING FOR ILIAC VEIN COMPRESSION FOR MAY-THURNER SYNDROME (PREAUTHORIZATION REQUIRED)


Description

Reflux is the primary pathology in chronic venous insufficiency (CVI). Management and treatment of varicosities has been the mainstay for many years.  There may be a small subset of individuals who would benefit from stenting of the Iliac vein when obstruction is present, such as in cases of May-Thurner syndrome.  The indications for intervention are not well defined. 1  Also routine interrogation of the iliac system cannot be recommended at this time. 4

UptoDate defines May Thurner as “hemodynamically significant compression of the left common iliac vein between the overlying right common iliac artery and the underlying vertebral body. May-Thurner syndrome, or iliac vein compression syndrome is a common anatomic pattern in normal subjects, which has been associated with unprovoked left iliofemoral deep venous thrombosis (DVT) or chronic venous insufficiency. Data indicates that this can be a normal variant found in asymptomatic individuals.2,3,5 

May Thurner is generally seen in females.  They may have episodes of deep vein thrombosis, unilateral leg swelling or redness or discoloration of the skin of the lower leg.  Stenting in this situation has been shown to be beneficial in patients with severe disabling symptoms. 4,6,7

Policy

Iliac vein stenting is scientifically validated for the treatment of May Thurner syndrome (iliac vein compression syndrome) with the following symptoms:

               Unilateral leg swelling and pain; AND

               The patient has a definitive diagnostic imaging study such as venogram, CT or MRI of May Thurner’s syndrome (iliac vein compression); AND

               Skin changes associated with venous insufficiency or ulcerations AND history DVT or post thrombotic syndrome; AND

               Patient has failed 3 months of conservative management with compression stockings, leg elevation and management of any thromboses

Iliac vein stenting is considered investigational for all other diagnoses as not supported by the medical literature.  Other procedures such as bilateral iliac vein stenting, embolization or stenting of hypogastric veins, embolization or stenting of gonadal veins in association with unilateral iliac vein stenting are not medically necessary. 

 

The patient has had a definitive diagnostic venography, CT or MRI
