A 59-year-old male with a history of gallbladder adenocarcinoma receiving chemotherapy and on therapeutic anticoagulation for portal vein thrombosis presented to the emergency department via ambulance after being found unresponsive and in cardiac arrest. Initial workup upon return of spontaneous circulation revealed a large right atrial mass, patent foramen ovale (PFO), and bilateral acute cortical infarctions. This constellation of findings were concerning for PFO-related paradoxical embolic strokes. Given the risk of recurrent paradoxical embolic events and the absolute contraindication to thrombolysis due to recent cerebral infarction, the decision was made to proceed with percutaneous vacuum-assisted thrombectomy using the AngioVac device. To prevent intraoperative thrombus propagation, PFO-closure was performed immediately prior to thrombectomy. Aspiration thrombectomy and PFO-closure were successful with complete thrombus removal and no intraoperative thrombus propagation. This case presents a minimally invasive and rapid treatment for a complex problem. An efficient and effective interdisciplinary team-based approach allowed the patient to resume cancer treatment relatively unabated.
一位 59 岁男性,既往有胆囊腺癌病史,正在接受化疗并接受抗凝治疗以预防门静脉血栓形成,因发现无反应和心脏骤停而被救护车送往急诊科。自主循环恢复时的初步检查发现了一个大的右心房肿块、卵圆孔未闭(PFO)和双侧急性皮质梗死。这些发现提示 PFO 相关的矛盾性栓塞性中风。鉴于复发性矛盾性栓塞事件的风险以及由于最近的脑梗死导致溶栓的绝对禁忌证,决定使用 AngioVac 装置进行经皮真空辅助血栓切除术。为了防止术中血栓传播,在血栓切除术之前立即进行 PFO 闭合。抽吸血栓切除术和 PFO 闭合均成功,完全清除了血栓,且术中无血栓传播。本例提出了一种微创、快速的治疗复杂问题的方法。高效、有效的多学科团队方法使患者能够相对不受影响地恢复癌症治疗。
