Application of 68Ga-Pentixafor PET/CT in Primary Aldosteronism and Pre-postoperative of SAAE

Positron-Emission Tomography Clinical Trial

Official title: 68Ga-Pentixafor PET/CT in the Diagnosis of Primary Aldosteronism and Pre-postoperative of Superselective Adrenal Artery Embolization

Status Recruiting

Clinical Trial Summary

Primary aldosteronism is the most common cause of secondary hypertension. The two main types of primary aldosteronism are aldosteronoma(30%) and adrenal hyperplasia(60%). The gold standard that determines the diagnosis and treatment strategy of primary aldosteronism is adrenal vein sampling(AVS), but the success rate is only about 80%. Using CXCR4 as a probe for 68Ga-Pentixafor PET/CT imaging can guide the classification diagnosis and treatment strategy of primary aldosteronism, which is a favorable supplement to AVS. Superselective adrenal artery embolization(SAAE) and laparoscopy are the main operation treatments for primary aldosteronism. SAAE is an invasive interventional operation. It is a novel way to evaluate the changes in the structure and function of adrenal tissue pre-postoperative SAAE by using the changes in 68Ga-Pentixafor PET/CT imaging.

Clinical Trial Description

Primary aldosteronism: Hypertension is divided into primary hypertension and secondary hypertension. Secondary hypertension refers to hypertension with clear etiology. When the etiology is identified and effectively removed or controlled, hypertension as a secondary symptom can be cured or significantly relieved. The most common secondary hypertension is primary aldosteronism. Primary aldosteronism is due to excessive aldosterone secretion in the adrenal cortex, characterized by clinical syndromes of hyperaldosteronism, low renin activity, hypertension and hypokalemia. Compared with essential hypertension, the risk of cardiovascular and cerebrovascular events and the risk of target organ damage in patients with primary aldosteronism were significantly increased. On the contrary, early detection and treatment mean better blood pressure control, lighter target organ damage and better clinical outcomes. The two main types of primary aldosteronism are aldosteronoma(30%) and adrenal hyperplasia(60%). The gold standard that determines the diagnosis and treatment strategy of primary aldosteronism is adrenal vein sampling (AVS), but the success rate is only about 80 %. Therefore, it is necessary to explore a non-invasive examination method as a beneficial supplement to AVS. ;
