1. Preoperative evaluation for the promising “arterial embolization treatment” to relieve stubborn chronic pain

TAME (arterial embolization treatment) is an emerging treatment for chronic inflammatory pain, and many patients who have long suffered from chronic pain have benefited. However, TAME is not suitable for everyone! Before considering TAME, patients must undergo a detailed evaluation by a specialist physician, including a thorough inquiry about pain symptoms and medical history, as well as a comprehensive physical examination to understand the nature, location, duration of the pain, and factors that may affect it.

When taking a chronic pain history, the doctor will ask about past illnesses, surgeries, medications, and family history to fully understand the patient's overall health. The physical examination includes assessment of posture, gait, range of motion, muscle strength, and neurological reflexes to identify potential causes or problems. In addition, preoperative imaging studies such as X-rays, CT, or MRI play a crucial role in evaluating the affected area.

Through imaging studies, physicians can more clearly observe changes in structures such as bones, joints, and soft tissues, and then determine the cause of the pain. In some special situations, the use of contrast agents can detect lesions more precisely. To ensure safety during the procedure, preoperative blood tests are also required, mainly to check kidney function and coagulation function, to make sure the patient's condition meets surgical requirements.

2. Who is not suitable for “arterial embolization treatment”? Doctor points out: 4 groups need careful evaluation

Which patients may not be suitable for TAME? First, patients allergic to X-ray contrast agents or therapeutic agents; second, those with severe renal impairment; third, patients taking anticoagulants or antiplatelet drugs. If patients are taking the above medications, they usually need to stop taking them 5 days before surgery to avoid affecting the procedure and increasing the risk of bleeding. Fourth, chronic pain that is too close to the cerebral vessels or spinal vessels is also less suitable for intervention with TAME. In addition, other systemic diseases such as immune system disorders, acute or chronic infectious diseases, etc., should also be fully disclosed to the physician before surgery for comprehensive evaluation.

After TAME treatment, appropriate pressure dressing at the puncture site to stop bleeding and keeping it dry are crucial to avoid complications such as infection or bleeding. It is generally recommended to avoid lifting heavy objects or engaging in weight-bearing activities within 1 to 2 weeks after surgery to reduce pressure on the puncture site and promote wound healing. Standard or simple repair time should be performed by a physician experienced in cardiac catheterization procedures to reduce the risk of complications. Physicians in pain medicine or radiology need to pay special attention to precision and perform the procedure under imaging guidance to avoid incorrect injection, ensuring that the medication flows through the blood vessels to the lesion and achieves the best therapeutic effect.

A small number of patients may experience local skin ulceration after TAME treatment, hematoma due to bleeding around the artery, or temporary redness and numbness/tingling at the treatment site. However, these symptoms usually gradually improve within a month, so patients need not worry too much. However, if numbness, coldness, or discomfort occurs in the hands or feet, or if there is persistent bleeding or expanding bruising at the puncture site, seek medical attention immediately and inform the doctor that arterial puncture and abnormal vascular embolization treatment were performed so that timely management can be provided.
