Resection of Lung Cancer with Left Atrium Extension via the Pulmonary Vein: Case Report
نویسندگان
چکیده
A 49-year-old man had an abnormal shadow on chest X-ray. Enhanced chest computed tomography (CT) revealed an 8-cm diameter right lung mass invading the right chest wall, with a tumor thrombus extending from the superior pulmonary vein into the left atrium. Transesophageal echocardiography confirmed that the tumor adjoined the side wall of the atrium. Endobronchial and CT-guided needle biopsy demonstrated a low-grade carcinoma or small cell carcinoma. Operative findings through left atriotomy under cardiopulmonary bypass showed no tumor invasion of the atrium wall, but protrusion through the pulmonary vein. Frozen sections revealed a non-small cell carcinoma. We performed right upper lobectomy with parietal pleura and mediastinal lymph node dissection after detachment of cardiopulmonary bypass. Pathological examination demonstrated a large-cell neuroendocrine carcinoma p-T4N0M0, stage IIIA. The patient recovered without postoperative complications and tolerated two cycles of adjuvant chemotherapy. He was doing well without symptoms of recurrence 42 months after surgery.

Left Atrial Mass Invasion from Pulmonary Neoplasm Extension via the Right Upper Pulmonary Vein Presenting as Ipsilateral Stroke
Left atrial invasion by lung cancer via haematogenous pathways is a relatively uncommon but potentially life-threatening event. While several cardiac complications of cardiac involvement have been previously described, the evolution towards cerebral stroke has been rarely reported. In this case report, we describe an atypical case of haematogenous metastatic invasion of the left atrium from pul...

Pulmonary thromboembolism (PTE) is a clinically critical disease, misdiagnosis or delayed diagnosis of which can lead to increased rate of mortality. For prevention of recurrence of PTE, recognition of its risk factors or underlying diseases is of great importance. PTE is common in patients with cancer and has high morbidity and mortality rates. Although cancer is a lethal condition, PTE accele...
متن کاملLeft atrial extension of metastatic lung tumor via pulmonary vein: report on the first case of Ewing sarcoma
Extension of metastatic lung tumors into the left atrium via pulmonary veins is rare. Here, we report the first case of Ewing sarcoma exhibiting such extension. A 31-year-old man with pulmonary metastasis from Ewing sarcoma presented with a mass in the left lung, extending to the left atrium through the left inferior pulmonary vein. As the patient was considered to be at risk of tumor embolism,...

Primary leiomyosarcoma of the heart is extremely rare and found in about 0.2% of all cardiac tumors. Here in a 26-year-old man with progressive dyspnea, which had started since 2 months ago, is presented. Echocardiography revealed a left atrial mass, which was suggestive for a atrial myxoma.On the surgery, a tumoral tissue in the left atrium and pulmonary veins with attachment to peripheral sof...

A 67-year-old man presented with dyspnoea and non-specific chest pain. A CT scan showed a mass lesion within the right superior pulmonary vein protruding into the left atrium (fig 1A, B). Positron emission tomography with fluoro-2-deoxy-Dglucose showed uptake within the lesion but no extrathoracic disease (fig 1C). A clinical-radiological diagnosis of pulmonary venous angiosarcoma was made and ...
