手臂发麻还头晕？元凶竟是血管在“偷”大脑的血！专家提醒：动脉粥样硬化患者需提高警惕

Core Viewpoint - A successful minimally invasive intervention was performed on a 67-year-old patient to treat severe stenosis of the subclavian artery, alleviating symptoms and reducing the risk of cerebral ischemia [1][2][3]. Group 1: Patient Condition and Diagnosis - The patient experienced symptoms such as coldness and numbness in the left arm for six months, initially attributing it to aging [2]. - A CTA scan revealed 70% stenosis in the left subclavian artery, leading to a "blood theft syndrome" where blood flow was redirected from the vertebral artery to the affected area [2][3]. - This condition resulted in significant consequences, including persistent numbness in the arm and potential long-term ischemia in the brain, causing dizziness [2]. Group 2: Surgical Procedure - The surgical team opted for a balloon angioplasty and stent placement due to the patient's age and medical history [3]. - The procedure was performed under local anesthesia, utilizing a small incision in the groin to access the artery [3]. - Post-surgery imaging confirmed successful restoration of blood flow, with immediate improvement in the patient's symptoms [3]. Group 3: Risk Factors and Warning Signs - The condition is commonly seen in middle-aged and elderly individuals with atherosclerosis, particularly those with hypertension, diabetes, hyperlipidemia, and a history of smoking [4]. - Early warning signs include unexplained unilateral arm symptoms, a significant difference in blood pressure between arms, and signs of cerebral ischemia [4].
