UNASSIGNED:使用肺静脉(PV)射频消融治疗心房颤动(AF)可能会并发PV狭窄或闭塞。有症状患者的常见治疗方法是经导管介入治疗,包括经皮腔内球囊血管成形术和支架植入术。支架植入本身,然而,可能是复杂的支架内狭窄。
UNASSIGNED:一名26岁男子因房颤隔离两个肺静脉后,由于两个左肺静脉完全闭塞,出现了恶化的劳力性呼吸困难。胸部计算机断层扫描(CT)显示胸部不对称和左肺巩固。患者接受了球囊血管成形术和两个左静脉支架置入术,导致症状的改善,步行距离,根据基于CT的容积法,肺空间容积增加120毫升。十个月后,患者经历了类似症状的复发。诊断为左上PV的支架再狭窄程度高,下PV的支架再狭窄程度中等,并进行了血管成形术。干预后第3天,患者临床情况良好,出院。
UNASSIGNED:肺静脉狭窄或闭塞的非特异性症状,比如呼吸急促,疲劳,流感样症状,降低物理性能,咯血延迟了诊断.如果肺静脉隔离后突然出现异常症状,应考虑肺静脉狭窄。在这种情况下,我们首次描述了两种肺静脉血运重建后肺实质的部分可逆性巩固.
UNASSIGNED: The use of pulmonary vein (PV) radiofrequency ablation for atrial fibrillation (AF) treatment may be complicated by PV stenosis or occlusion. A common curative treatment for symptomatic patients is a transcatheter intervention, including percutaneous transluminal balloon angioplasty and stent implantation. Stent implantation itself, however, can be complicated by in-stent stenosis.
UNASSIGNED: A 26-year-old man presented with worsening exertional dyspnoea due to a total occlusion of both left PVs after the isolation of two PVs for AF. Chest computed tomography (CT) showed chest asymmetry and consolidation of the left lung. The patient was treated with balloon angioplasty and stent placement of both left PVs, resulting in improvement of symptoms, walking distance, and increase in lung space volume by 120 mL based on CT-based volumetry. Ten months later, the patient experienced a recurrence of similar symptoms. A high grade in stent restenosis of the upper left PV and moderate in stent restenosis of the lower PV were diagnosed and treated with angioplasty. The patient was discharged from the hospital in good clinical condition 3 days after the intervention.
UNASSIGNED: Non-specific symptoms of PV stenosis or occlusion, such as shortness of breath, fatigue, flu-like symptoms, reduced physical performance, and haemoptysis delay the diagnosis. If unusual symptoms appear abruptly after PV isolation, a PV stenosis should be considered. In this case, we describe for the first time a partially reversible consolidation of lung parenchyma following the revascularization of both PVs.
