Unusual case of spontaneous hemopneumothorax in a Tunisian pulmonology department: a case report.

Spontaneous hemopneumothorax is a rare encountered entity in clinical practice. It can be life threatening, so a prompt diagnosis and therapeutic intervention are required. We report a case of a right spontaneous hemopneumothorax in a 31-year-old man, complicated with hemorrhagic shock. Conservative therapy with only thoracic drainage with close monitoring of outflow and hemodynamic parameters was performed. In front of hemodynamic instability, an emergency video-assisted thoracoscopic surgery was performed. An apical bulla adhering to the parietal pleura has been identified as the source of the bleeding. The resection of the bullae and electrocauterization of the bleeding adhesion were effectuated. The hemostasis was easily achieved. The actual experience suggests that video-assisted thoracoscopic surgery should be performed as soon as possible after the diagnosis of spontaneous hemopneumothorax. Indeed, conservative therapy with chest drainage should only be performed as bridge to recovery for the stabilization before the video-assisted thoracoscopic surgery.

Hemopneumothorax detection through the process of artificial evolution - a feasibility study.

BACKGROUND: Tension pneumothorax is one of the leading causes of preventable death on the battlefield. Current prehospital diagnosis relies on a subjective clinical impression complemented by a manual thoracic and respiratory examination. These techniques are not fully applicable in field conditions and on the battlefield, where situational and environmental factors may impair clinical capabilities. We aimed to assemble a device able to sample, analyze, and classify the unique acoustic signatures of pneumothorax and hemothorax. METHODS: Acoustic data was obtained with simultaneous use of two sensitive digital stethoscopes from the chest wall of an ex-vivo porcine model. Twelve second samples of acoustic data were obtained from the in-house assembled digital stethoscope system during mechanical ventilation. The thoracic cavity was injected with increasing volumes of 200, 400, 600, 800, and 1000 ml of air or saline to simulate pneumothorax and hemothorax, respectively. The data was analyzed using a multi-objective genetic algorithm that was used to develop an optimal mathematical detector through the process of artificial evolution, a cutting-edge approach in the artificial intelligence discipline. RESULTS: The in-house assembled dual digital stethoscope system and developed genetic algorithm achieved an accuracy, sensitivity and specificity ranging from 64 to 100%, 63 to 100%, and 63 to 100%, respectively, in classifying acoustic signal as associated with pneumothorax or hemothorax at fluid injection levels of 400 ml or more, and regardless of background noise. CONCLUSIONS: We present a novel, objective device for rapid diagnosis of potentially lethal thoracic injuries. With further optimization, such a device could provide real-time detection and monitoring of pneumothorax and hemothorax in battlefield conditions.

Severe haemophilia A in a neonate presenting as haemopneumothorax after tracheo-oesophageal fistula-oesophageal atresia repair.

A male infant with oesophageal atresia and distal tracheo-oesophageal fistula (TEF type C) underwent right thoracotomy and transpleural repair of TEF on day 4 of life. He did not have a family history of coagulation disorders. A preoperative finding of prolonged partial thromboplastin time (PTT)>200 s was overlooked, and he went to surgery. There were no concerns with haemostasis prior to and even during the operation. The prolonged PTT was treated with one 10 mL/kg dose of fresh frozen plasma in the immediate postoperative period. On the fourth postoperative day, the infant developed a right haemopneumothorax, requiring fresh frozen plasma and packed cell transfusions. He was subsequently diagnosed with severe haemophilia A due to intron 22 inversion in the factor VIII gene, with factor VIII level <0.01 IU/mL.

Emergency video-assisted thoracoscopic surgery for haemopneumothorax and diaphragm repair after stabbing, performed through pre-existing wounds.

Video of video-assisted thoracoscopic surgery (VATS) on a 16-year old who had been stabbed. The knife penetrated the diaphragm, lung and intercostal pedicle causing a haemopneumothorax. A chest drain was inserted by the trauma team. VATS was performed entirely through the stab and chest drain pre-existing wounds without extension.

Penetrating chest injuries caused by swordfish sword used as a weapon.

We report 5 cases of penetrating chest wounds caused by weapons made from swordfish swords, involving breakage of the sword that later appeared as a thoracic foreign body. The patients had been assaulted 2 days to 17 years earlier. Three of them had a chronic infected wound, one had a penetrating thoracic wound with hemopneumothorax, and one had a foreign body. Computed tomography showed a foreign body in the lung in 4 cases, with aortic penetration in one. The foreign body was removed via thoracotomy in all 4 patients, with aorta repair in one who presented later with a pseudoaneurysm.

Traumatic Diaphragmatic Hernia: Diagnostic Dilemma.

Traumatic rupture of the diaphragm is an uncommon condition. The prevalence of diaphragmatic rupture among blunt trauma victim ranges from 0.8 to 8%. The etiologic factors are blunt trauma (for example, in motor vehicle accidents) and penetrating trauma. The diagnosis is often missed because of non-specific clinical signs, and the absence of additional intra-abdominal and thoracic injuries. We present a case which was misdiagnosed as a case of left sided hemopneumothorax and treated with tube thoracotomy in other center.

Traumatic pulmonary pseudocyst: An underreported entity.

BACKGROUND: Traumatic pulmonary pseudocysts (TPP) are underreported cavitary lesions of the pulmonary parenchyma that can develop following blunt chest trauma. Although the occurrence of traumatic pulmonary pseudocyst is rare, this condition should be considered in the differential diagnosis of any cavitary lesion. Awareness of this injury and its clinical significance is important for successful management in order to avoid medical errors in the course of treatment. METHODS: A literature search was conducted through Medline using the key phrases "traumatic pulmonary pseudocyst" and "traumatic pneumatocele." Relevant articles, especially those with focus on diagnosis and management of traumatic pneumatocele in adults, were selected. Due to the scarcity of literature and lack of Level I evidence on this subject, studies published in any year were considered. RESULTS: A search of "traumatic pulmonary pseudocyst" and "traumatic pneumatocele" yielded 114 studies. Most of these were excluded based on inclusion and exclusion criteria. Thirty-five articles were reviewed. The majority of these were individual case studies; only eight articles were considered large case studies (greater than eight patients). CONCLUSION: Traumatic pulmonary pseudocysts are lesions that occur secondary to blunt chest trauma. Diagnosis is based on a history of trauma and appearance of a cystic lesion on CT. Accurate diagnosis of traumatic pulmonary pseudocyst is imperative to achieve successful outcomes. Failure to do so may lead to unnecessary procedures and complications.

Traumatic haemopneumothorax and 'whole-body' subcutaneous emphysema: successful use of a small-bore chest drain.

A 56-year-old man presented having had two falls at home. He had a background of multiple sclerosis. After his second fall, during which he had fallen onto the toilet injuring his right chest, he was brought into the emergency department reporting pleuritic chest discomfort. Immediately evident was extensive swelling from his forehead to his thighs, which on palpation was found to be subcutaneous emphysema. A chest X-ray showed a large right-sided pneumothorax for which a chest drain was inserted. A CT revealed extensive surgical emphysema, pneumomediastinum, pneumoperitoneum and gas within the spinal canal. It also showed right-sided rib fractures and associated haemothorax. He was managed conservatively with a 12-French (F), small-bore, chest drain and made a complete recovery without complication. This case challenges the widely held, but poorly evidenced, opinion that traumatic haemopneumothorax needs to be managed with a large-bore surgical chest drain.

Traumatic pulmonary pseudocyst due to thoracic trauma.

Traumatic pulmonary pseudocyst is uncommon and usually regresses spontaneously with conservative treatment. In rare cases, surgical intervention may be necessary. A pseudocyst may be treated surgically to prevent potential complications if the patient undergoes a thoracotomy for another reason. We present a patient with hemopneumothorax and traumatic pulmonary pseudocyst after a motor vehicle accident, who was operated on electively due to massive air leak.

Pneumothorax-associated fibroblastic lesion in combination with localized pleural angiomatosis: A possible cause of juvenile spontaneous hemopneumothorax.

Spontaneous hemopneumothorax is an uncommon but potentially life-threatening condition, with a potential for a rapid ventilatory collapse and a large collection of hidden blood loss into the pleural cavity. Here, we report the first case in the literature on pneumothorax-associated fibroblastic lesion in combination with localized pleural angiomatosis in a 19-year-old Caucasian male, resulting in massive spontaneous hemopneumothorax and hypovolemic shock. Our findings support a causal link between this condition and pneumothorax. The possible superimposed hemothorax is explainable by the pleural involvement of large angiomatous vessels, prone to rupture.

Primary spontaneous haemopneumothorax: an overlooked emergency.

Primary spontaneous haemopneumothorax (PSHP) is a rare condition. Potentially grave consequences do occur as a result of a failure to reach the diagnosis early. We report a case of a 17-year-old male who presented with a picture of PSHP but was later also found to have a component of haemothorax. He underwent thoracoscopy which was converted to thoracotomy. A torn vascular adhesion was the source of bleeding which was clipped and haemostasis was achieved.

Spontaneous hemopneumothorax simulating acute abdominal affections.

Spontaneous hemopneumothorax (SHP) is a rare potentially life-threatening condition that occurs in predominantly young adolescents. The resultant massive hemorrhage leading to hypovolemic shock can be a surgical emergency. It constitutes 1-12% of all spontaneous pneumothoraces and presents with two cardinal features, chest pain and dyspnea. However, the pain of SHP may be confined to the abdomen secondary to the irritation of diaphragmatic pleura, which produces signs simulating an acute abdomen. SHP masquerading as an abdominal affection is apparently regarded as extremely rare. We present a case of a 16-year-old male with SHP presenting features simulating acute gallbladder disease. After prompt diagnosis with appropriate surgical intervention, he had an uneventful recovery. Our experience emphasizes the importance of careful and thorough chest examination for each child with atypical pictures for abdominal pain to exclude possible extra-abdominal lesions, even rare as SHP.
