Indwelling Pleural Catheters

Indwelling pleural catheters (IPC) are now being considered worldwide for patients with recurrent pleural effusions. It is commonly used for patients with malignant pleural effusions (MPE) and can be performed as outpatient based day care procedure. In malignant pleural effusions, indwelling catheters are particularly useful in patients with trapped lung or failed pleurodesis. Patients and care givers are advised to drain at least 3 times a week or in presence of symptoms i.e. dyspnoea. Normal drainage timing may lasts for 15–20 min which subsequently improves their symptoms and quality of life. Complications which are directly related to IPC insertion are extremely rare. IPC’s are being recently used even for benign effusions in case hepatic hydrothorax and in patients with CKD related pleural effusions. Removal of IPC is often not required in most of the patients. It can be performed safely as a day care procedure with consistently lower rates of complications, reduced inpatient stay. They are relatively easy to insert, manage and remove, and provide the ability to empower patients in both the decisions regarding their treatment and the management of their disease itself.

Surgical Management of Pleural Space Infection

Pleural space infections are a common clinical entity affecting a large number of patients. These are associated with considerable morbidity and mortality rate and they require significant healthcare resources. In this chapter, we discuss the disease characteristics with regards to the etiology (primary and secondary), clinical presentation, radiological findings, different stages of the condition and treatment options according to stage at presentation. Conservative management (medical treatment, pleural drainage, with or without intrapleural fibrinolytic) may be effective in management of simple pleural space infections, but surgical management may be required in loculated complex empyema to prevent acute sepsis, deterioration and trapped lung. Surgical treatment of complicated pleural infections either by VATS or thoracotomy will be discussed in order to understand when to perform debridement/decortication of the pleural cavity or less frequently a thoracostomy.

Short and long-term outcomes of surgical intervention for empyema in the post-fibrinolytic era

Background Open window thoracostomy (OWT) is indicated for patients with bronchopleural fistula (BPF) or trapped lung in the setting of empyema refractory to non-surgical interventions. We investigated the role of OWT in the era of minimally invasive surgeries, endobronchial valves and fibrinolytic therapy. Methods A retrospective chart review of all patients who underwent OWT at a single institution from 2010 to 2020 was performed. Indications for the procedure as well as operative details and morbidity and mortality were evaluated to determine patient outcomes for OWT. Results Eighteen patients were identified for the study. The most common indication for OWT was post-resectional BPF (n = 9). Prior to OWT, n = 11 patients failed other surgical or minimally invasive interventions. Patient comorbidities were quantified with the Charlson Comorbidity index (n = 11 score ≥ 5, 10-year survival ≤21%). Three (16.7%) patients died < 30 days post-operatively and 12 (66%) patients were deceased by the study’s end (overall survival 24.0 ± 32.2 months). Mean number of ribs resected were 2.5 ± 1.2 (range 1–6) with one patient having 6 ribs removed. Patients were managed with negative pressure wound therapy (n = 9) or Kerlix packing (n = 9). Eleven patients (61.6%) underwent delayed closure (mean time from index surgery to closure 4.8 ± 6.7 months). Conclusions Our study illustrates the significant comorbidities of patients undergoing OWT, the poor outcomes therein, and pitfalls associated with this procedure. We show that negative pressure wound therapy can be utilized as potential way to obliterate the pleural space and manage an open chest in the absence of an airleak; however, OWT procedures continue to be extremely morbid.

Use of Intrapleural Fibrinolytic Therapy in a Trapped Lung following Acute Traumatic Haemothorax

Retained haemothorax is a common sequela of traumatic haemothorax and refers to blood that cannot be drained from the pleural cavity. We report a case of trapped lung secondary to retained haemothorax in a patient who sustained a penetrating chest injury. Initial chest computed tomography (CT) showed a large haemothorax that was managed with an intercostal drain insertion (ICD). Repeat chest CT and thoracic ultrasonography performed after ICD removal showed an organized pleural space resembling haematoma. ICD was reinserted with administration of intrapleural fibrinolytic therapy (IPFT). Subsequent chest CT showed the development of a pleural rind and trapped lung. A second ICD was inserted, and further IPFT were administered together with aggressive negative pressure suction. Haemoglobin remained stable. The patient made a full recovery and imaging performed two weeks later showed minor blunting of the costophrenic angle. This case highlights the feasibility and safety of IPFT in the management of trapped lung associated with traumatic retained haemothorax as an alternative to surgery.

Organizing Pneumonia and Microvascular Fibrosis as Late Sequelae after a COVID-19 Infection. A Case Report

We report a patient with COVID-19 requiring hospitalization for two weeks, complicated by multiple segmental pulmonary embolisms for which dabigatran was initiated. After clearing the infection, the patient remained asymptomatic for 5 months. He was then readmitted with a spontaneous haemothorax, most likely related to the use of dabigatran, which progressed to a pleural empyema with a trapped lung. The patient underwent a video assisted thoracoscopy (VATS) with decortication. Because of focal abnormalities, biopsies for histopathology were taken from the lung parenchyma. These showed an organizing pneumonia with progression towards fibrosis and arteries with intimal fibrosis. So far, no histopathological reports exist on late pulmonary changes after a COVID-19 infection. The unusual combined presence of microvascular damage and interstitial fibrosis may reflect a pathophysiological concept in which early endothelial damage by SARS-CoV-2 can lead to a chronic state of microvascular damage, low grade inflammation, and early progression towards pulmonary fibrosis.
