Massive hemoptysis caused by bronchiectasis in which bronchial artery embolization does not control the bleeding is not rare. Traditional surgical intervention is anatomical lung resection. We present a case of a patient with bronchiectasis and massive hemoptysis in which the bleeding was controlled with transection of a pulmonary vein and bronchus with preservation of the pulmonary artery.
Massive hemoptysis is a life threatening condition, and the treatments include bronchoscopic intervention, bronchial artery embolization, and surgical intervention. Some case reports of controlling hemoptysis by either division of the bronchus or ligation of the pulmonary artery for the control of bleeding have been published. We report a case with massive hemoptysis which was treated successfully by only transecting the pulmonary vein and bronchus.
After adequate resuscitation with blood products, embolization of the left brachial artery was performed. However, some proximal collateral vessels which could not be embolized remained. After the procedure, persistent hemoptysis was noted, and therefore surgical intervention was taken.
After induction of general anesthesia, the patient was intubated with a double-lumen endotracheal tube and placed in the right decubitus position. Two trocars were inserted at 6th and 8th intercostal spaces, respectively, and a 15-cm thoracic incision in the 5th intercostal space was made and a rib retractor was placed. Severe adhesions in the pleural space were found, and all were detached. The major fissure and pulmonary artery were difficult to identify because of severe consolidation of the left lung. The border between the left upper lobe and left lower lobe was unclear. Enlargement and marked tortuosity of the bronchial arteries were also found, and these vessels were ligated with sutures. Pneumonectomy was considered, however, it was not performed in consideration of the high potential mortality. The inferior pulmonary vein was transected to allow identification of the left lower lobe bronchus. The bronchus of the left lower lobe was then transected to control the hemoptysis, and the pulmonary artery was preserved. Two 32F straight chest tubes were placed after checking for bleeding and air-leakage.
No hemoptysis was noted postoperatively, and the patient’s fever subsided by postoperative day 10. The chest tubes were removed on postoperative day 18, and he was discharged on postoperative day 24. The postoperative course was uneventful.
Hemoptysis is a common symptom in bronchiectasis patients. However, other causes of hemoptysis include tuberculosis, mycetomas, necrotizing pneumonia, and bronchogenic carcinomas [1, 2]. Treatments for massive hemoptysis include cold saline lavage, epinephrine, endobronchial stent tamponade, bronchial artery embolization, and invasive surgical intervention. The standard surgical procedure for the treatment of hemoptysis is anatomic lung resection (pneumonectomy, lobectomy, segmentectomy). Nonanatomic (wedge) resection should be avoided due to greater risk of failure to control the bleeding [3, 4].
In our initial purpose, anatomic resection of lung (left lower lobe lobectomy) was planned to do. Due to severe bronchiecstasis and inflammation, there’s much extremely tortuous and engorged collateral arteries around. We therefore decided to resect the pulmonary vein first and then the bronchus and pulmonary artery sequentially. But the severe adhesion fissure and tortuous vessels made the dissection of pulmonary artery unachievable after the bronchus resected. What’s more, the border of left upper and lower lobe also got severe inflammation and adhesion. Pneumonectomy seems the only way to get anatomic resection of lung in this patient. However, high risk and postoperative mortality was concerned and we decided to leave the pulmonary artery alone and perform a large wedge resection with both pulmonary vein and bronchus resected.
On searching related articles, we found no similar case reports. The only related procedure we found was resection of the pulmonary artery and bronchus whereas leave the pulmonary vein . In that procedure, the isolated lung continues to receive a blood supply from the vessels between the lung surface and the chest wall, which keeps the lung parenchyma viable. Moreover, the intact pulmonary veins drain the blood, and therefore no necrosis of the lung parenchyma occurs . In our case, the pulmonary artery was kept intact, and the pulmonary vein was resected. The bronchus of the left lower lobe was transected to control the hemoptysis. We considered that pneumonectomy for this patient was technical feasible to control the hemoptysis, but the associated risk of mortality was high. We wanted to preserve the lung function of left upper lobe, and therefore we resected the inferior pulmonary vein and bronchus and left the pulmonary artery. In follow-up imaging studies asymptomatic local lung consolidation with deficits in ventilation and perfusion were noted.
A combined ligation of the pulmonary vein and the bronchus to produce physiological lung exclusion for the control of hemoptysis hasn’t been reported. This case illustrates that this is a therapeutic option for controlling massive hemoptysis.
