why perform CT Upper Limb Angiography.

CT Upper Limb Angiography is performed to evaluate the blood vessels (arteries and veins) of the upper limb, from the shoulder down to the hand. This scan provides detailed images of vascular structures using contrast dye injected into a vein, which helps in identifying various conditions.

Indications for CT Upper Limb Angiography:

  1. Vascular Diseases:

    • Arterial stenosis (narrowing of arteries due to atherosclerosis)

    • Aneurysms (abnormal bulging of arteries)

    • Arteriovenous malformations (AVMs) and fistulas

  1. Trauma & Injury:

    • Suspected vascular injury after accidents or fractures

    • Penetrating injuries (gunshot, stab wounds)

  2. Thrombosis & Embolism:

    • Deep vein thrombosis (DVT) in upper limb veins

    • Arterial or venous embolism (blood clots blocking vessels)

  3. Pre-Surgical or Post-Surgical Evaluation:

    • Planning for vascular surgery or interventions (e.g., bypass, stent placement)

    • Post-operative monitoring of vascular grafts or stents

  4. Vasculitis & Autoimmune Disorders:

    • Detecting inflammation of blood vessels (e.g., Takayasu arteritis, Buerger’s disease)

  5. Thoracic Outlet Syndrome (TOS):

    • Evaluating vascular compression due to anatomical abnormalities

  6. Tumor Assessment:

    • Identifying tumor involvement of blood vessels

Procedure Overview:

  • A contrast dye (iodine-based) is injected via an intravenous (IV) catheter.

  • CT scanner captures high-resolution images of blood vessels.

  • The scan takes only a few minutes, but preparation may take longer.

Advantages:

✔️ Non-invasive
✔️ Provides high-resolution vascular imaging
✔️ Helps in planning treatments like angioplasty or surgery
