Bilateral Re-expansion Pulmonary Edema after Cardiac Surgery Successfully Treated with Venovenous Extracorporeal Membrane Oxygenation / 日本心臓血管外科学会雑誌

A 57-year-old man was admitted with high fever and chest discomfort associated with aortic valve infective endocarditis. An echocardiogram showed severe aortic valve regurgitation. An emergent operation was performed. The aortic valve was destroyed and an annulus abscess was observed. Aortic valve replacement was performed. There was a large amount of pleural effusion in both chest cavities. Bilateral chest drainage was performed. Cardiopulmonary bypass weaning was performed uneventfully. The operation was finished without any mechanical support required. However, respiratory failure was observed to progress rapidly immediately after the operation. A postoperative X-ray showed bilateral pulmonary edema. Re-expansion pulmonary edema was diagnosed. Because oxygenation was not improved in ventilator settings, venovenous extracorporeal membrane oxygenation (V-V ECMO) was installed. Respiratory support with V-V ECMO was needed for 17 days postoperatively. It took 36 days before the patient was removed from the ventilator. V-V ECMO successfully managed bilateral re-expansion pulmonary edema.

Stent-Graft Re-expansion Following Axillo-Bifemoral Bypass : A Case of Stent Graft Collapse due to Acute Type B Aortic Dissection / 日本心臓血管外科学会雑誌

We describe a rare complication and treatment progression that occurred in a 64-year-old man with an aortic abdominal aneurysm (AAA) that had been treated by endovascular aneurysm repair (EVAR). He had undergone EVAR to treat an infra-renal type AAA 21 months previously and returned to the emergency department with back pain. Contrast-enhanced computed tomography (CT) revealed acute type B aortic dissection, so he was admitted and conservative medical management was started. Acute stomachache and limb pain appeared on hospital day 7, which prevented him from moving his lower limbs. The main body of the stent graft had collapsed, blocking blood flow, and contrast was not found in arteries from the collapsed stent graft portion to the knee level on emergency contrast CT images of the leg. His legs were revascularized by an extra-anatomical right axial-bilateral external iliac bypass. His symptoms disappeared and reperfusion injury was avoided. The collapsed stent graft had retained its original shape at 11 and 18 days after surgery. Furthermore, follow-up CT 4.5 years later showed that the stent graft retained its original form.

Edema pulmonar de reexpansión en avenamiento pleural por neumotórax / Re-expansion pulmonary edema afer pleural drainage of pneumothorax

Se trata de un paciente masculino de 28 años que consultó por dolor torácico izquierdo, acompañado de disnea de 4 días de evolución. La radiografia de tórax confirmó la sospecha de neumotórax izquierdo. Cuarenta minutos después de realizado el avenamiento pleural izquierdo, el paciente comenzó con tos productiva y disnea. La radiografia de tórax evidenció infltrados en el pulmón izquierdo. La tomografia computarizada de tórax confirmó el edema pulmonar de reexpansión. El paciente cursó la internación en terapia intensiva con tratamiento de soporte. Se retró el tubo de tórax al sexto día y se otorgó el alta hospitalaria.

A 28 year old man presented with lef thoracic pain and dyspnea for the four previous days. Chest X-ray evidenced a lef pneumothorax. Forty minutes afer inserton of a pleural drainage, the patent complained of dyspnea and productive cough. A new chest X-ray showed pulmonary infltrates in the lef lung. A computed tomographic scan was consistent with re-expansion pulmonary edema. The patent spent a postoperative course in the intensive care unit with suportive therapy. The pleural drain was withdrawn on the sixth day, and was discharged home.

Re-expansion Pulmonary Edema after Mitral Valve Plasty via Small Right Thoracotomy / 日本心臓血管外科学会雑誌

We report a case of re-expansion pulmonary edema (REPE), which complicated mitral valve plasy via right small thoracotomy. A 56-years old man underwent mitral valve plasty for severe mitral regurgitation caused by P2 prolapse. After separation from heart-lung machine, massive yellow foamy secretion has begun to spout from the right side endotracheal tube and hypoxemia has ensued. Differential ventilation with high airway pressure and steroid pulse therapy could not counteract the exacerbation of hypoxemia. Echocardiography showed severe diffuse hypokinesis of left ventricular wall. Intra-aortic balloon pumping and percutaneous cardiopulmonary support (PCPS) were introduced, and they were very effective. After five-days' support, PCPS was successfully weaned. The patient recovered well. REPE complicated by mini-thoracotomy approach cardiac surgery, is rare, but can be fatal.

Two Cases of Reexpansion Pulmonary Edema after Cardiac Surgery / 日本心臓血管外科学会雑誌

A 54-year-old man with ischemic mitral regurgitation underwent surgical ventricular restoration, mitral valve plasty and a coronary artery bypass. A chest X-ray 7 days later revealed pleural effusion on the right side. A chest tube was inserted and about 1,000 ml of fluid was drained. However, re-expansion pulmonary edema (RPE) occurred 2 h later. Positive pressure ventilation and intravenous infusion with a diuretic improved the RPE. He was resuscitated on the following day to receive percutaneous cardiopulmonary support (PCPS) for unstable hypoxemia and hypotension. Oxygenation improved, PCPS was withdrawn 2 days later, and the endotracheal tube was removed. Re-expansion pulmonard. He was resuscitated on the following day to receive percutaneous cardiopulmonary support (PCPS) for unstable hypoxemia and hypotension. Oxygenation improved, PCPS was withdrawn 2 days later, and the endotracheal tube was removed. Re-expansion pulmonary edema might cause fatal short-term cardio-respiratory failure. We considered that RPE requires appropriate early diagnosis, early treatment and aggressive therapy, including PCPS.

Fatal re-expansion pulmonary oedema in a mechanically ventilated patient.

Fatal course of re-expansion pulmonary oedema (REPO) is infrequent and very rarely documented in mechanically ventilated patients. We report a case of fatal REPO following tube thoracostomy for a right-sided pneumothorax in an elderly patient of chronic obstructive pulmonary disease (COPD) with respiratory failure on mechanical ventilation.

Ipsilateral Reexpansion Pulmonary Edema Developed after Decortication: A Case Report / 대한구급학회지

Reexpansion pulmonary edema (RPE) is a rare but sometimes fatal complication of the treatment of lung collapse secondary to pneumothorax, pleural effusion, or atelectasis. We experienced a case of RPE that developed following decortication. A 46 year-old female had a decortication for pyothorax under one-lung anesthesia. There was no event during the operation and results of arterial blood gas analysis were within normal limits. After the operation, tracheal extubation was performed and 100% oxygen saturation on a pulse oximeter (SpO2) was maintained with 100% O2, (8 L/min) via mask ventilation with self-respiration. The patient, with 50% Venturi mask, was transported to the intensive care unit (ICU). On arrival at the ICU, a SpO2 of 80% was detected and arterial blood gas analysis revealed hypoxemia with acute hypercapnic respiratory acidosis. Fortunately, reexpansion pulmonary edema was detected early and intensive treatment was performed using mechanical ventilation with positive end-expiratory pressure. Tracheal extubation was performed after 1 day of mechanical ventilation. The reexpansion pulmonary edema was successfully treated and the patient recovered without any complications.

Reexpansion Pulmonary Edema Following the Early Decompression of Pneumothorax Occurred after Anesthetic Induction in a Patient with Lung Bulla: A Case Report / 대한구급학회지

When a rapidly re-expanding lung has been in a state of collapse for more than several days, pulmonary edema sometimes occurs. This is called reexpansion pulmonary edema. In general, it most commonly occurs in patients with a large pneumothorax of long duration. In this case, a 15 year old female patient with a 2.3 cm sized bulla in the right lung developed right pneumothorax after anesthetic induction. Although early drainage by closed thoracostomy was performed, right pulmonary edema eventually occurred. It is unusual that vigorous reexpansion pulmonary edema developed even though early decompression was performed within one hour after development of pneumothorax.

High-Resolution CT Findings of Re-Expansion Pulmonary Edema

OBJECTIVE: To describe the high-resolution CT (HRCT) findings of re-expansion pulmonary edema (REPE) following a thoracentesis for a spontaneous pneumothorax. MATERIALS AND METHODS: HRCT scans from 43 patients who developed REPE immediately after a thoracentesis for treatment of pneumothorax were retrospectively analyzed. The study group consisted of 41 men and two women with a mean age of 34 years. The average time interval between insertion of the drainage tube and HRCT was 8.5 hours (range, 1-24 hours). The patterns and distribution of the lung lesions were analyzed and were assigned one of the following classifications: consolidation, ground-glass opacity (GGO), intralobular interstitial thickening, interlobular septal thickening, thickening of bronchovascular bundles, and nodules. The presence of pleural effusion and contralateral lung involvement was also assessed. RESULTS: Patchy areas of GGO were observed in all 43 patients examined. Consolidation was noted in 22 patients (51%). The geographic distribution of GGO and consolidation was noted in 25 patients (58%). Interlobular septal thickening and intralobular interstitial thickening was noted in 28 patients (65%), respectively. Bronchovascular bundle thickening was seen in 13 patients (30%), whereas ill-defined centrilobular GGO nodules were observed in five patients (12%). The lesions were predominantly peripheral in 38 patients (88%). Of these lesions, gravity-dependent distribution was noted in 23 cases (53%). Bilateral lung involvement was noted in four patients (9%), and a small amount of pleural effusion was seen in seven patients (16%). CONCLUSION: The HRCT findings of REPE were peripheral patchy areas of GGO that were frequently combined with consolidation as well as interlobular septal and intralobular interstitial thickening.

A Case of Focal Reexpansion Pulmonary Edema after Chest Tube Insertion / 결핵및호흡기질환

Reexpansion pulmonary edema is not a common phenomenon after chest tube insertion but some reports from 0% to 14%. There are various resulting complications, including acute respiratory distress syndrome. We report a case of focal reexpansion pulmonary edema after chest tube insertion. A 49-year-old male came to the hospital due to ongoing dyspnea and left chest pain for 3 days. On chest X-ray, the patient had a left pneumothrax. We planned to insert a chest tube for symptom relief. To determine whether or not the chest had expanded as a result of the chest tube insertion, the patient underwent repeated chest X-rays the following day. The patient experienced brief respiratory symptoms upon initial suction; a chest PA showed patchy consolidated infiltration at the inserted site. After 5 days of conservative management, the recovered completely.

Unilateral pulmonary edema after two-jaw surgery: A case report / 대한마취과학회지

Pulmonary edema is usually bilateral, but can be uncommonly unilateral. Although unilateral pulmonary edema (UPE) can occur owing to various etiologies, it usually occurs at a patient who has an underlying defect or abnormality in the cardiopulmonary system except a case of negative-pressure pulmonary edema. Especially UPE following general anesthesia is a rare complication in a healthy patient. Re-expansion pulmonary edema (REPE) as a cause of UPE mostly occurs when a chronically collapsed lung is rapidly re-expanded after pneumothorax. There are some reports associated with REPE following one-lung ventilation used to facilitate surgery, in which there is no chronically collapsed lung. There are, however, little reported cases of a more acute form of this complication following re-expansion after atelectasis due to only several minutes of an inadvertent main stem bronchial intubation during operation. A report of the occurrence of UPE in a healthy, young male undergoing two-jaw surgery is described.

Hydrothorax after Central Vein Catheterization for Right Internal Jugular Vein and Contralateral Reexpansion Pulmonary Edema after Right Chest Tube Insertion: A case report / 대한마취과학회지

Cannulation of a large central vein is the standard clinical method for mornitoring CVP and is also performed for a number of additional therapeutic interventions, such as providing secure vascular access for administration of vasoactive drugs or to initiate rapid fluid resuscitation in operation or for aspiration of air emboli. But there are many complications such as vessel injury, pneumothorax, nerve injury, arrhythmias, arteriovenus thrombus, pulmonary emboli, infection at insertion site, because there are major vessels, nerve and organs around of central veins. We report a case of Rt. Hydrothorax after internal jugular vein cannulation and a contralateral reexpansion pulmonary edema and pleural effusion after Rt. chest tube insertion for hydrothorax.

Reexpansion Pulmonary Edema Occurred after Evacuating the Hepatic Hydrothorax in a Liver Transplant Patient: A case report / 대한마취과학회지

A hepatic hydrothorax is a pleural effusion that develops in patients with cirrhosis and portal hypertension in the absence of cardiopulmonary disease. It is a complication of end-stage liver disease, and a liver transplant is the treatment of choice. In our case, a reexpansion pulmonary edema occurred after evacuating 4,250 ml of ascites and aspirating 3,600 ml of the pleural effusion within 15 minutes aimed at visually improving the surgical field in a 46-year-old male patient receiving a liver transplant. 1 hour 30 minutes after aspirating the pleural effusion, the level of oxygen saturation decreased from 100% to 95%, and serosanguinous fluid spilled over from the endotracheal tube. We inserted a double lumen endotracheal tube to both separate and protect the unaffected left lung, and applied CPAP 10 cmH2O at the affected right lung. The reexpansion pulmonary edema was successfully treated using this supportive management.

Re-expansion Pulmonary Edema after Chest Tubing: A Case Report / 대한구급학회지

Re-expansion pulmonary edema (RPE) is a rare complication associated with the treatment of collapsed lung caused by pneumothorax, atelectasis, pleural effusion in which a large amount of air or effusion fluid is evacuated. In general RPE is resulted from more than 3 days of lung collapse and application of high negative intrapleural pressure. However, it is reported that RPE could be developed despite the collapse period is short and negative pressure suction is not performed. It also has been known that the rate of reexpansion is more important than amount of evacuated air, or collapse period in the development of RPE. Seventeen-year-old female was undergone suture hemostasis for liver laceration, in which RPE was occurred after closed thoracostomy for pleural effusion on postoperative-27 day. We present a case report with review of related articles.

Re-expansion Pulmonary Edema after Laparoscopic Bariatric Surgery: A case report / 대한마취과학회지

Laparoscopic procedures are accompanied by an increased intra-abdominal pressure and diaphragmatic elevation, which may interfere with adequate ventilation in obese patients. Re-expansion of a collapsed lung could be followed by pulmonary edema. Here, we describe a case of re-expansion pulmonary edema after laparoscopic bariatric surgery. A 23-year-old-female with morbid obesity received general anesthesia for laparoscopic adjustable gastric banding surgery. Unintentional one lung ventilation occurred for a short period during the operation and was promptly corrected. At the end of the operation, as spontaneous respiration recovered, profuse pinkish frothy sputum emerged from the endotracheal tube. Diffuse patchy increased opacity on the left lung field was observed by chest X-ray. With aspiration of bronchial secretion and oxygen supplementation, the patient was recovered uneventfully. We presume that inadequate lung expansion during pneumoperitoneum and unintentional right endobronchial intubation caused atelectasis of the left lung, and induced re-expansion pulmonary edema at the end of the operation. This case emphasizes the importance of constant vigilance with respect to endotracheal tube position and ventilation during laparoscopic surgery in obese patients.

A Case of Focal Reexpansion Pulmonary Edema after Conventional Thoracentesis of Pleural Effusion / 결핵

A 60-year old male patient admitted with complaints of dyspnea and pleuritic chest pain. The chest X-ray demonstrated right pleural effusion. We planed to do the conventional thoracentesis to evaluate the characteristics of pleural effusion and to relieve the symptom of the patient. Focal reexpansion pulmonary edema was seen on the follow-up chest X-ray. After the 5-day conservative management, the patient recovered without any complications.

Differential Lung Ventilation Therapy for Reexpansion Pulmonary Edema: Report of 2 cases / 대한흉부외과학회지

Reexpansion pulmonary edema is a rare complication of the treatment of lung collapse secondary to pneumothorax, pleural effusion, or atelectasis. But occasionally, severe morbidity and death may result. Reexpansion pulmonary edema occurs when chronically collapsed lung is rapidly reexpanded by evacuation of large amounts of air or fluid. In the treatment of the chronically collapsed lung, physicians must remember the possible events and prevent the complications. When the difference in airway resistance or lung compliance between the two lungs is exaggerated, conventional mechanical ventilation might lead to preferential ventilation with hyperexpansion of one lung and gradual collapse of the other. Differential ventilation has been advocated to avert this problem. By differential lung ventilation, we successfully treated a severe reexpansion pulmonary edema in two patients. Therefore we suggest that differential lung ventilation is the treatment of choice for severe reexpansion pulmonary edema.

Edema pulmonar de reexpansão tratado com ventilação não invasiva: relato de caso / Reexpansion pulmonary edema treated with non-invasive ventilation: case report

The authors report a case of Reexpansion Pulmonary Edema (RPE) seen at Hospital de Pronto Socorro de Porto Alegre 3 hours after drainage of spontaneous pneumothorax. The patient presented a unilateral pneumothorax with one-week duration. After pleural drainage respiratory failure occured being managed at the Intensive Care Unit with non-invasive positive pressure ventilation through facial mask. The patient had favorable outcome and was discharged asymtomatic after 72 hours.

A Case of Bilateral Reexpansion Pulmonary Edema After Pleurocentesis / 결핵

Acute bilateral reexpansion pulmonary edema after pleurocentesis is a rare complication. In one case, bilateral reexpansion pulmonary edema after unilateral pleurocentensis in sarcoma was reported. Verious hypotheses regarding the mechanism of reexpansion pulmonary edema include increased capillary permeability due to hypoxic injury, decreased surfactant production, altered pulmonary perfusion and mechanical stretching of the membranes. Ragozzino et al suggested that the mechanism leading to unilateral reexpansion pulmonary edema involves the opposite lung when there is significant contralateral lung compression. Here we report a case of bilateral reexpansion pulmonary edema and acute respiratory distress syndrome after a unilateral pleurocentesis of a large pleural effusion with contralateral lung compression and increased interstitial lung marking underlying chronic liver disease.

Factors Affecting Brain Re-expansion after Simple Burr Hole Drainage in Chronic Subdural Hematoma

Delayed brain re-expansion is one of the most frequent problems on the chronic subdural hematoma. The aim of this study is to determine the factors affecting brain re-expansion. The study consists of 76 patients with the chronic subdural hematoma treated primarily by simple burr-hole drainage from January 1992 to December 1996. Clinical records and radiologic studies were reviewed retrospectively. The age distribution ranged from 22 to 82 years(mean 64 years), the male-to-female ratio was 1.8:1(49:27). At the 2nd, 4th, 6th and 12th week after surgery, the follow-up study was performed with computed tomography or magnetic resonance image. Complete brain reexpansion was defined as that the subdural space was 5mm or less without midline shift on computed tomography or magnetic resonance image. The factors interfering the brain re-expansion are as follows; d age, low Glasgow Coma Scale(GCS) score on admission, history of chronic alcohol consumption, hypodense hematoma on computed tomography, bilateral hematoma, disappearance of intraoperative brain pulsation, and long duration after trauma. The results of this study may be helpful to predict the brain re-expansion after simple burr-hole drainage. If the complete brain re-expansion is not observed immediately, it should be waited for 6 weeks to conduct the follow-up study. Patient's position and sufficient hydration are important for brain expansion. Further investigations on other factors related to promotion of the brain re-expansion should be followed.
