"Transarterial Microembolization (TAME) in Inflammatory Knee Pathology"

Официальное название

"Transarterial Microembolization (TAME) in Inflammatory Knee Pathology: Prospective Observational Study."

Обзор

Patients with knee OA and chronic pain refractory to at least 3 months of conventional conservative therapy will be included in the study, which will evaluate the clinical results obtained after treatment with selective arterial embolization (selection and enrollment, treatment with selective arterial embolization, follow-up checks). Forty-three patients will be included in the study and will undergo the transarterial microembolization procedure after signing the informed consent form for participation in the study and the collection of anamnestic data. Subsequently, patients will be followed up with clinical evaluation at 1, 3, 6, 12, and 24 months of follow-up or until possible dropout for other treatment.

Подробное описание

Degenerative and inflammatory joint disease is a common and debilitating condition that causes pain and limited mobility, with osteoarthritis (OA) being the most common form. The knee is the most commonly affected joint, with an estimated 600 million people worldwide currently living with unilateral or bilateral knee OA, marking a 113% increase since 1990. Although risk factors include obesity, advanced age, and female gender, most individuals are susceptible to the pathophysiological cascade of OA, which likely explains the dramatic global burden of the disease and its associated economic consequences. These joint disorders have a significant impact on individuals' quality of life. When they occur in mild or moderate form, a series of therapeutic strategies can be implemented, but these rarely lead to a significant reduction in pain and do not alter the course of the disease. Standard treatment includes exercise, postural measures, weight control, and pharmacotherapy. Intra-articular injections of hyaluronic acid or platelet-rich plasma (PRP) have emerged as new non-surgical treatment options. Surgical joint replacement is reserved for the most severe cases, with intense pain and functional disability. However, many patients suffer from refractory chronic pain, are not candidates for surgery, or refuse it. In addition, some patients may experience complications associated with long-term pharmacotherapy, such as renal or hepatic failure, opioid dependence, or local problems resulting from injections, such as infections. In recent years, geniculate artery embolization has emerged as a promising option for patients with knee pain due to OA who are refractory to conservative therapies and who are not eligible for or choose not to undergo arthroplasty surgery.

Patients with knee OA and chronic pain refractory to at least 3 months of conventional conservative therapy will be included in the study, which will evaluate the clinical results obtained after treatment with selective arterial embolization (selection and enrollment, treatment with selective arterial embolization, follow-up checks). Forty-three patients will be included in the study and will undergo the transarterial microembolization procedure after signing the informed consent form for participation in the study and the collection of anamnestic data. Subsequently, patients will be followed up with clinical evaluation at 1, 3, 6, 12, and 24 months of follow-up or until possible dropout for other treatment.

Вмешательства

• Процедура Transarterial Microembolization
  Identification of the hypervascularization of the knee. Selective and super-selective catheterization of pathological genicular arterial branches, through the use of micro-catheters. - Injection of embolizing material (Nexsphere-F - Kardia) - Control of technical success: the embolization will be followed by diagnostic arteriography that will evaluate the success of the procedure (occlusion of more than 90 percent of the pathologic vasculature).
