Indicators of haemothorax in patients with spontaneous pneumothorax

Spontaneous hemopneumothorax causing life-threatening hemorrhage: a case report

BACKGROUND

Spontaneous hemopneumothorax is a rare condition that can be life-threatening if not promptly diagnosed and treated. We report a case of early treatment with transcatheter arterial embolization and video-assisted thoracoscopic surgery.

CASE PRESENTATION

A 19-year-old Japanese male was diagnosed with left pneumothorax and underwent chest tube drainage. A total of 10 hours after admission, the patient developed dyspnea, chest pain, and sudden massive bloody effusion. Contrast-enhanced computed tomography revealed contrast extravasation near the left lung apex, and spontaneous hemopneumothorax was diagnosed. Angiography revealed bleeding from a branch of the subscapular artery and transcatheter arterial embolization was performed. The patient underwent video-assisted thoracoscopic surgery and recovered uneventfully.

CONCLUSIONS

Anesthesiologists involved in urgent surgeries must be aware that a patient with spontaneous pneumothorax can develop a hemopneumothorax, even when full lung expansion has been obtained following chest tube drainage, owing to latent aberrant artery disruption. Interprofessional team engagement is essential for spontaneous hemopneumothorax management.

A Rare but Life-Threatening Case of Spontaneous Hemopneumothorax in a Young Male

Spontaneous hemopneumothorax (SHP) is the spontaneous accumulation of both blood and air within the pleural space without any previous medical or trauma history. Despite its rare existence, it is one of the most life-threatening conditions seen in the emergency department. Even though SHP is an uncommon presentation, early recognition and prompt intervention are essential because of its rapidly deteriorating nature leading to respiratory distress and hemodynamic instability. This is a case of a 20-year-old male who presented in the emergency room complaining of sudden chest pain and respiratory distress. After physical examination and radiological investigation, a diagnosis of left-sided spontaneous hemopneumothorax was the top differential that consisted of the patient's presentation and chest X-ray. Subsequently, a chest tube was inserted to drain the blood in the pleural cavity. In addition to the presence of blood in the chest tube, the serum hemoglobin levels of the patient were low, which suggested the diagnosis of hemopneumothorax. After that, the patient underwent video-assisted thoracoscopic surgery (VATS) which demonstrated a significant amount of pleural blood clots, pleural adhesions, and apical blebs in the lung. Through this procedure, the source of the bleeding was found to be a ruptured adhesion in the left lung. By the end of this surgical intervention, the adhesions were cauterized and the blebs were resected. Post-operatively, the patient stabilized and had a full lung expansion upon follow-up. This case emphasizes the importance of early recognition, diagnosis, and prompt surgical management of SPH to prevent life-threatening complications.

Spontaneous hemopneumothorax after laparoscopy: a case report and literature review

BACKGROUND

Spontaneous hemopneumothorax (SHP) is defined as the accumulation of >400 mL of blood in the pleural cavity in association with spontaneous pneumothorax. This rare clinical disorder may be life-threatening.

CASE PRESENTATION

A 71-year-old woman presented with a 1-month history of recurrent bloody stool, and electronic colonoscopy suggested a rectal mass. Laparoscopic radical resection of rectal cancer was performed. Two days later, she developed chest tightness, shortness of breath, and slight pain in the left chest. Emergency chest radiography revealed mild left pneumothorax and pleural effusion. SHP was suspected and a thoracic drain was inserted. However, the patient developed hemorrhagic shock 3 hours after drainage. She underwent emergency video-assisted thoracic surgery (VATS), which revealed left lung tip rupture with bleeding and adhesive band fracture at the top of the left thoracic cavity. The ruptured lung tissue was removed and electrocoagulation at the adhesion band was performed for hemostasis. The patient was discharged on postoperative day 11. At the time of this writing, she had developed no SHP recurrence or any other complications.

CONCLUSIONS

This case shows that conservative treatment may have serious consequences in patients with SHP. Thus, chest X-ray examination and VATS should be performed in patients with SHP.

Hemothorax: A Review of the Literature

Hemothorax is a collection of blood in the pleural cavity usually from traumatic injury. Chest X-ray has historically been the imaging modality of choice upon arrival to the hospital. The sensitivity and specificity of point-of-care ultrasound, specifically through the Extended Focal Assessment with Sonography in Trauma (eFAST) protocol has been significant enough to warrant inclusion in most Level 1 trauma centers as an adjunct to radiographs.^1,2 If the size or severity of a hemothorax warrants intervention, tube thoracostomy has been and still remains the treatment of choice. Most cases of hemothorax will resolve with tube thoracostomy. If residual blood remains within the pleural cavity after tube thoracostomy, it is then considered to be a retained hemothorax, with significant risks for developing late complications such as empyema and fibrothorax. Once late complications occur, morbidity and mortality increase dramatically and the only definitive treatment is surgery. In order to avoid surgery, research has been focused on removing a retained hemothorax before it progresses pathologically. The most promising therapy consists of fibrinolytics which are infused into the pleural space, disrupting the hemothorax, allowing for further drainage. While significant progress has been made, additional trials are needed to further define the dosing and pharmacokinetics of fibrinolytics in this setting. If medical therapy and early procedures fail to resolve the retained hemothorax, surgery is usually indicated. Surgery historically consisted solely of thoracotomy, but has been largely replaced in non-emergent situations by video-assisted thoracoscopy (VATS), a minimally invasive technique that shows considerable improvement in the patients' recovery and pain post-operatively. Should all prior attempts to resolve the hemothorax fail, then open thoracotomy may be indicated.

A 79-year-old-man with a 'niveau' on a chest radiograph

A 79-year-old man was referred to the emergency room following a sudden episode of 'spitting blood', with a blood pressure of 128 (systolic) and 75 mm Hg (diastolic) and a heart rate of 60 bpm. His medical history included the treatment of gastric cancer and untreated hypertension. At that time, his symptoms were limited without any chest, back or abdominal pain. After a presentation of haemoptysis was confirmed, a chest radiograph revealed an air-fluid level (a 'niveau') that was continuous towards the enlarged thoracic aorta and the thoracic cavity. Contrast-enhanced CT was subsequently performed, and revealed an aortic dissection and a pneumothorax adjacent to the dissection, accompanied by blood pooling in the thoracic cavity. The patient died 40 min after the admission to the emergency room due to an additional haemoptysis. The autopsy confirmed the diagnosis of a ruptured aortic dissection with pneumothorax.

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.

Spontaneous hemopneumothorax: epidemiological details and clinical features

PURPOSES

Spontaneous hemopneumothorax (SHP) may cause life-threatening blood loss. The objective of this study was to elucidate the epidemiological and clinical features of SHP.

METHODS

We reviewed the records of 26 patients who underwent surgery for SHP between 1989 and 2010. We evaluated their epidemiology and clinical features by comparing them with those of 681 patients with spontaneous pneumothorax treated during the same period.

RESULTS

The proportion of smokers in the SHP group was higher than that in the spontaneous pneumothorax group (P < 0.01). Seventeen cases (65.4 %) of SHP occurred on the left side. The most frequent bleeding area was the superior thoracic aperture (STA:17 cases, 65.4 %), followed by the left superior mediastinum (six cases, 23.1 %). Ten cases had intrathoracic clots greater than 500 mL, which could not be drained preoperatively. The postoperative stay of patients treated with video-assisted thoracic surgery (VATS) was shorter than that of patients treated with open thoracotomy (21 versus five cases; P < 0.05).

CONCLUSIONS

A higher proportion of smokers was revealed in the SHP patients. VATS shortened the hospital stay of the patients. The particular areas that should be observed intraoperatively are the STA and the left superior mediastinum.

Simultaneous bilateral primary spontaneous pneumothorax

OBJECTIVE

While primary spontaneous pneumothorax (PSP) is common in adolescents and young adults, simultaneous bilateral PSP (SBPSP) is rare and can be life-threatening if it progresses to tension pneumothorax. This study reviewed cases of PSP to identify the clinical features of SBPSP.

METHODS

All patients with PSP diagnosed and treated between June 1996 and June 2006 were reviewed, and the clinicoradiological features and outcomes were evaluated.

RESULTS

Of the 616 patients with 807 episodes of PSP, 13 had SBPSP (1.6%) at first presentation, and all were male (mean age 20.9 +/- 4.7 years, range 16-25 years). Compared with the non-SBPSP patients, SBPSP patients had significantly lower body weight and BMI (P = 0.018 and <0.001, respectively) and higher body height/body weight ratio (P = 0.004). There was no significant difference in their age, sex, smoking habits or body height. Patients with SBPSP had a significantly higher incidence of bleb/bullae seen in HRCT of the lung compared with non-SBPSP (88.5% vs 63.5%, P = 0.016). In multiple logistic regression analysis, BMI and presence of blebs/bullae were independent risk factors for SBPSP. All patients with SBPSP received bilateral video-assisted thoracoscopic surgery and recovered uneventfully. The mean follow-up period was 3.7 years (range 10 months-7 years).

CONCLUSION

Patients with PSP having a lower BMI, and bilateral bleb/bullae formation are at higher risk for the development of SBPSP. SBPSP needs urgent assessment and management, and bilateral video-assisted thoracoscopic surgery is a safe and effective treatment.

Spontaneous hemopneumothorax in children: case report and review of literature

Spontaneous hemopneumothorax is rare, occurs in young adolescents, and can be life threatening secondary to massive bleeding. An adolescent with spontaneous hemopneumothorax and shock managed by tube thorascostomy is described here. We compared our case with published data of spontaneous hemopneumothorax in the pediatric age group. Spontaneous hemopneumothorax involves the accumulation of air and blood in the pleural space in the absence of trauma or other obvious causes. Spontaneous hemopneumothorax is usually seen in adolescents, more common in males than females. The common clinical features of spontaneous hemopneumothorax include dyspnoea and chest pain, and 30% present with hypovolemic shock. The bleeding can result from a torn adhesion between the parietal and visceral pleurae, from a rupture of vascularized bullae, or from torn congenital aberrant vessels. Over the last 6 decades, the treatment has progressed from the thoracotomy to minimally invasive techniques such as video assisted thoracoscopic surgery, with great reduction in mortality and recurrence rates. Although a rare entity, diagnosis of spontaneous hemopneumothorax must be considered in young adolescents presenting with spontaneous onset of chest pain and dyspnoea with radiograph findings of hydropneumothorax and/or signs of shock.

Spontaneous hemopneumothorax

PURPOSE OF REVIEW

Spontaneous hemopneumothorax can be life threatening, and is a cause of patients presenting with unexplained signs of significant hypovolemia. The debate relating to patient selection and timing of surgery in patients with spontaneous hemopneumothorax remains unresolved.

RECENT FINDINGS

Our experience together with the latest series published over the last decade on the conservative and surgical management of spontaneous hemopneumothorax are presented and discussed.

SUMMARY

Surgery should be performed early in the management of spontaneous hemopneumothorax to reduce morbidity. In particular, video-assisted thoracic surgery, which is associated with potentially fewer post-operative complications and shorter hospital stays compared with thoracotomy, should be considered in patients with spontaneous hemopneumothorax who are hemodynamically stable.
