Successful Autologous Blood Patch Pleurodesis: A Safe and Useful Treatment for Persistent Pneumothorax in Former Pulmonary Tuberculosis and Aspergillosis in Pregnant Women

Background: Autologous Blood Patch Pleurodesis (ABPP) is one of the treatment options for persistent pleural air leaks especially in patients who are not suitable for surgical intervention. Persistence pneumothorax is defined as pneumothorax of more than five days duration. It is associated with increased morbidity and cost of care. The most widely accepted treatment for it is pleurodesis. Several types of pleurodesis have been proposed, including surgical approaches and the instillation of different chemicals in the intrapleural space. ABPP has proven to be a simple, inexpensive, efficacious and safe method. We present the case of the first patient with Persistent Pneumothorax we have treated Successfully with ABPP. ABPP is currently rarely and uncommonly used, but it provides benefits especially in special conditions with easier, cheaper, and quite effective procedures.
 Case: A female 35-year-old pregnant women patients with Former Tuberculosis (FTB) come to our hospital with complaints breathlessness and chest pain worsening since 3 days before admitted to our hospital. Chest radiography showed spontaneous pneumothorax with GeneXpert (GE) sputum Mtb Not Detected but there is Aspergillosis from Fungal Culture. Water Sealed Drainage (WSD) was inserted in right pleural for almost 1 month and this patient discharge with pneumostat. One month after that she come again with Persistence Pneumothotax, so that we do the pleurodesis with Blood Patch and get the improvement from clinical status. Antifungals are continued for an initial 4-6 weeks while an outpatient evaluation is conducted.
 Conclusion: ABPP is a safe, inexpensive and efficacious treatment for persistent pleural air leak. Autologous Blood Patch administration may be considered for patients with Persistent Pneumothorax.

Successful management of a persistent pneumothorax in a cat using an autologous blood patch pleurodesis

AbstractA 16‐year‐old, neutered, male cat presented to an emergency and specialty care facility for persistent pneumothorax. Bilateral thoracocentesis, biochemical and hematological evaluation, thoracic radiographs, abdominal ultrasound, heartworm antigen test and computed tomography scan were performed. No definitive cause of the pneumothorax was identified, making a diagnosis of spontaneous (idiopathic) pneumothorax most likely.  Surgical exploration of the thorax was declined. Evacuation of the pleural space was performed for 4 days, without resolution of air accumulation. An autologous blood patch pleurodesis was performed on the fifth day. The pneumothorax resolved, and the patient was discharged from the hospital the following day. Recheck radiographs were performed 17 days after discharge, which confirmed resolution of pneumothorax. The patient was alive 1200 days after discharge, with no recurrent clinical signs. This case report demonstrates successful use of an autologous blood patch pleurodesis in a feline patient.

Management of persistent air leak in Neonates: A case series

Background: Autologous blood patch pleurodesis (ABPP) has been used in adults as an efficient and safe technique to address persistent air leak (PAL). A fibrin glue patch is also an alternative, but its elevated cost and technique can limit its routine use. Evidence of their use in the pediatric population, specifically in the neonatal age is scant. Case Presentation: We share our management experience in a series of 3 cases. The first 2 were treated exclusively with ABPP and showed clinical and radiographic improvement. The 3rd case, due to the persistence of the air leak, required extended thoracotomy and fibrin patch placement. Conclusion: The use of ABPP as an alternative for the treatment of neonates with PAL is a safe and efficient technique. The procedure is replicable and can be done at the bedside at a low cost. A fibrin glue patch should be considered as an alternative option when ABPP fails to resolve the leak.

Autologous blood patch pleurodesis for management of persistent pneumothorax in a dog with metastatic osteosarcoma

AbstractA 10‐year‐old, neutered, male Pitbull was presented to the oncology service with dyspnoea, approximately 16 months after treatment with amputation and chemotherapy for appendicular osteosarcoma, and 4 months after development of diffuse pulmonary metastatic disease. Thoracic radiographs diagnosed bilateral pneumothorax, presumed secondary to metastatic osteosarcoma. The pneumothorax was refractory to conservative management, and two autologous blood patch pleurodesis procedures were performed 48 hours apart, according to a previously published protocol. Marked radiographic improvement was evident within 24 hours of the autologous blood patch pleurodesis procedures, and the dog was discharged 6 days after initial presentation. Approximately 13 weeks later, the dog was humanely euthanased due to progressive clinical signs. This report describes the development of spontaneous persistent pneumothorax secondary to osteosarcoma metastatic disease in a dog, and its palliation with autologous blood patch pleurodesis. This case demonstrates that autologous blood patch pleurodesis can be considered as a treatment option for pneumothorax secondary to metastatic disease in dogs.

Autologous blood patch pleurodesis for persistent air leak in the setting of chronic non-invasive ventilation: case report

Background: Persistent air leaks (PAL) are associated with significant morbidity and mortality, including prolonged length of hospital stays, increased re-admission rates and increased incidences of pneumonia and pleural space infections. Autologous blood patch pleurodesis (ABPP) may be used in the management of PAL, however it is unclear whether this treatment option can be used in patients requiring chronic non-invasive ventilation.

Autologous Blood Patch Pleurodesis for Secondary Spontaneous Pneumothorax: A Narrative Review, a Retrospective Case Series and State of Play in the UK.

Treatment of prolonged air leak due to secondary spontaneous pneumothorax is challenging. Autologous blood patch pleurodesis (ABPP) is a treatment option. Previous evidence is reliant on single-centre series and underpowered trials and is mostly described in air leaks post cardiothoracic intervention. There are no United Kingdom (UK) wide data. Members of the UK Pleural Society were surveyed for their practice and for patients who underwent blood patch. There were 16 respondents from 333 members. Twelve had performed the procedure, and six had kept records and could submit data. Basic demographics, intervention and clinical details of patients were then collected. The study was sponsored by the Audit Department of Northumbria Healthcare NHS Foundation Trust (reference 8124), and Caldicott Clearance for data sharing was provided by the Trust's Information Goverance Board (reference C4221). There was no requirement for informed consent. Data for 12 patients that received ABPP between 2014 and 2022 in six respiratory centres were assessed. The aetiology of the secondary pneumothoraces was mostly due to chronic obstructive pulmonary disease and end-stage interstitial lung disease. The patients had a median age of 75years. The median air leak time before ABPP was 17days. A total of 50-100 ml of blood was used for ABPP. Five patients had two attempts at ABPP. Air leak resolved in six patients (50%). Four patients had pleural apposition prior to ABPP. Four patients were diagnosed with hospital-acquired pneumonia following ABPP. This is the only UK-wide retrospective case series of ABPP of 'medical' patients with secondary pneumothorax. There is widespread variation in care. No formal conclusions can be drawn, and much larger robust datasets are required. An application has been made to the European Respiratory Society to incorporate ABPP within the International Collaborative Effusion database.

Early Pleurodesis for Postoperative Air Leak with Autologous Blood and 50% Glucose Solution

Postoperative air leaks after pulmonary resection prolong the duration of chest drainage and the length of hospital stay. One of the many treatment options is bedside pleurodesis using various agents. This study evaluated the feasibility of an early intervention to stop postoperative air leaks with either autologous blood or a 50% glucose solution. We retrospectively reviewed 323 patients who underwent bedside pleurodesis between January 2017 and March 2022. Sixty-four patients received autologous blood patch pleurodesis, and 36 were treated with a 50% glucose solution after pulmonary resection. The primary endpoints were the total postoperative tube indwelling time, post-pleurodesis tube indwelling time, and hospital stay. A propensity score-matched analysis was performed. In the autologous blood patch pleurodesis and 50% glucose solution groups, the mean initiation timing of postoperative pleurodesis were 2.06±1.62 and 3.28±1.56 days, the mean duration of the tube indwelling time after surgery was 6.58±3.02 and 6.42±4.92 days, and the mean duration of the tube indwelling time after pleurodesis, it was 4.53±3.10 and 3.11±4.80 days, respectively. In addition, the total length of hospital stay was 9.11±5.42 and 7.83±4.75 days in the autologous blood patch pleurodesis and 50% glucose solution groups, respectively. Early postoperative air leak cessation with autologous blood patch pleurodesis or 50% glucose solution pleurodesis is a feasible procedure with acceptable outcomes that effectively shortens the hospital stay.

Comparison of efficacy of autologous blood patch pleurodesis versus doxycycline pleurodesis in the management of persistent air leak in patients with secondary spontaneous pneumothorax. A randomized control trial.

Secondary spontaneous pneumothorax (SSP) patients sometimes have a persistent air leak (PAL) that leads to increased morbidity and increased hospital stay. Further, these patients also need pleurodesis to prevent a recurrence. Autologous blood patch pleurodesis (ABPP) has been successfully tried in post lobectomy air leak cases. However, its utility in SSP patients with PAL has not been widely established. In this context, we performed a non-blinded randomized control study to compare the efficacy of ABPP vs doxycycline pleurodesis in the closure of air leak in SSP patients. This study was a non-blinded randomized control study done in 38 SSP patients with PAL. They were randomized into doxycycline arm and ABPP arm. Post pleurodesis air leak was assessed every 12 hours for cessation. Success was considered when there was a complete cessation of air leak. Post-procedural complications were noted and patients were followed up for 28 days to look for recurrence. The median time for closure was 24 hours [interquartile range (12.24)] for ABPP and 36 hours [interquartile range (24.72)] for doxycycline pleurodesis. Success rate of ABPP vs doxycycline pleurodesis is 94.7% vs 84.2% (p=0.6). Post-procedure pain was more in doxycycline group (15% vs 73%) (p<0.01). On visual analogue scale, ABPP had a lesser pain as compared to doxycycline pleurodesis (average visual analogue scale value of 2 vs scale of 7). The recurrence rate was equal in both groups (5%). Though ABPP and doxycycline have similar success rates, ABPP has an early closure of air leak and greater patient tolerability. ABPP can be tried as an alternative to doxycycline pleurodesis in SSP patients with persistent air leaks.

Autologous Blood Patch Pleurodesis: A Reliable Treatment Option For Prolonged Air Leakage in Children

Objective: Persistent air leaks remain one of the most complications that delay chest tube removal and prolonged hospitalization. In literature, there are limited but favorable results about autologous blood patch pleurodesis (ABPP) for prolonged air leaks (PAL). We aimed to describe our experiences with ABPP for PAL regarding its effectiveness and reliability in children. Material and Methods: A retrospective single-center study was performed on patients under 18 years of age with PAL. PAL was defined as the presence of alveolar-pleural fistulas lasting longer than 5 days. The etiological causes including previous thoracic surgery, thoracic trauma, and spontaneous pneumothorax of PAL were included. The study took into account patients from January 1, 2016, to December 1, 2021. Autologous blood patch pleurodesis (ABPP) was performed through a pre-existing chest tube. 1-2 cc/kg of fresh whole blood that was taken from a peripheral vein and instilled through the existing chest tube on day 1. The procedure was repeated on days 2 and 4 if the air leak persisted with a maximum limit of three. During the follow-up period, complications of the procedure were evaluated. Complete success was considered as resolving air leaks. Results: Of 11 children, males were more common (n=7, 63.9%). The mean age of children who underwent ABPP for PAL was 13.4 2.1 years (IQR 10-17). The mean number of repeating procedures was 1.8 ranging from 1 to 3 applications. In our study group, thoracic procedures secondary to spontaneous pneumothorax were the most common etiologic cause. Most of the patients had PAL during forced expiration only (n=6, 54.5%), and the mean number of ABPP applications was found 1.7 in this group. But the patients having continuous PAL required 3.1 applications for improvement (mean value). Complete recovery was possible in six cases after the first application (54.5%). PAL improved in all cases after repeating ABPP procedures (100% healing). We had seen no complications in terms of respiratory distress due to the application of ABPP or infection. Conclusion: We report about our experiences of autologous blood patch pleurodesis (ABPP) in children as an alternative treatment option for PAL. ABPP is an easily applicable therapy with high effectiveness and being away from complications and, the use of ABPP for PAL was successful in all patients of our series.

Autologous Blood Patch Pleurodesis: A Large Retrospective Multicenter Cohort Study

BackgroundProlonged air leaks (PAL) complicate 10% to 15% of lung resections, delaying chest tube removal and prolonging length of hospital stay. No consensus exists for managing this common complication, despite favorable results for autologous blood patch pleurodesis (ABPP) in the literature. The aim of this study was to evaluate the effectiveness and safety of ABPP. MethodsWe retrospectively reviewed medical records of 510 patients with PAL after lobectomy in four centers between January 2010 and December 2019. They were divided into two groups: group A consisted of patients who received ABPP for PAL of more than 5 days; and group B was patients for whom no ABPP or other procedure was performed for PAL unless strictly necessary. Propensity score matched analysis was performed, and 109 patients were included in each group. Time to cessation of air leak and chest tube removal, length of hospital stay, reoperation, and complications rate were examined. ResultsAfter the propensity score matching, ABPP significantly reduced the number of days before chest tube removal (8.12 vs 9.30, P = .004), and length of hospital stay (10 vs 11 days, P = .045) with fewer perioperative complications (6 vs 17, P = .015). Furthermore, ABPP was related to lower incidence of any additional invasive procedures (0 vs 9, P = .002) and reoperation (0 vs 4, P = .044). No patient in the ABPP group had long-term complications related to pleurodesis. ConclusionsAutologous blood patch pleurodesis is safe and effective in reducing length of hospital stay and leads to earlier chest tube removal without increasing complications.

Autologous blood patch pleurodesis for prolonged postoperative air leaks.

BackgroundA prolonged air leak (PAL) is the most frequent complication after pulmonary resection. This study aimed to assess the safety and efficacy of autologous blood patch pleurodesis (ABPP) to treat PAL.MethodsA prospectively maintained database identified patients with a PAL after pulmonary resection for lung cancer between 2015–2019. In this observational cohort study, clinical data were collected to retrospectively compare patients undergoing ABPP to no ABPP in a propensity-matched analysis. Kaplan Meier estimates and Cox models accounting for inverse probability weighting (IPTW) were used to assess the association of ABPP with each outcome.ResultsOf the 740 patients undergoing lung resection, 110 (15%) were identified as having a PAL at postoperative day (POD) 5. There was no difference between baseline characteristics among those undergoing ABPP (n=34) versus no ABPP (n=76). Propensity-weighted analysis did not reveal a significant association of ABPP treatment with in-hospital complication (P=0.18), hospital length of stay (LOS) (P=0.13), or post-discharge complication (P=0.13). However, ABPP treatment was associated with a lower risk of hospital readmission [P=0.02, hazard ratio (HR) 0.16] and reoperation for air leak or empyema (P=0.05, HR 0.11). Although not statistically significant, the mean chest tube (CT) removal of 11 days for the ABPP group was less than the no ABPP group (16 days) (P=0.14, HR 1.5–2). Those treated with ABPP were less likely to be discharged with a CT (ABPP 7/34, 21% vs. no ABPP 40/76, 53%). There was no statistical difference in empyema development between groups (ABPP 0/34, 0% vs. no ABPP 4/76, 5%, P=0.39, HR 0.24).ConclusionsABPP administration is safe compared to traditional PAL management. In a retrospective propensity-matched analysis, postoperative patients treated with ABPP required less readmission and reoperation for PAL. Larger powered randomized trials may demonstrate the magnitude of benefit from treatment with ABPP.

[Pleurodesis with an Autologous Blood Patch in the Treatment of Persistent Air Leak after Lung Resection].

Objective To evaluate the efficacy and risks of autologous blood patch pleurodesis in patients with persistent air leak(PAL)after lung resection. Methods A total of 97 patients with PAL after lung resection in Beijing Shijitan Hospital from October 2014 to October 2019 were retrospectively reviewed,including 53 treated by autologous blood patch pleurodesis and 44 by the conventional way.The therapeutic effect,adverse reactions and complications were analyzed. Results All the patients with PAL were cured with autologous blood patch pleurodesis.Most air leaks(81.1%)ceased within 48 hours after treatment,and the left 18.9% patients got cured after a repeat.The mean tube retention time and the mean in-hospital stay were 8.4 days and 10.0 days in the autologous blood patch pleurodesis group and 13.5 days and 15.3 days in the conventional treatment group.A prolonged drainage time(P=0.00)and in-hospital stay(P=0.00)were observed in the conventional treatment group.No severe complications were observed except two patients developed slight fever and cutaneous emphysema. Conclusion In our experience,the autologous blood patch pleurodesis is an effective way with low risk of adverse reactions in the treatment of PAL.

Therapeutic use of autologous blood patch pleurodesis for continuous pneumothorax in a feline pyothorax

AbstractA continuous pneumothorax developed in a feline patient following placement of a thoracostomy tube in order to facilitate medical management of a pyothorax. Possible causes of the continuous pneumothorax include iatrogenic complications during tube placement, rupture of a possible pulmonary abscess, underlying neoplasia or concurrent inflammatory airway disease. The patient was placed on continuous suction with no improvement. Surgical exploration was declined. An autologous blood patch pleurodesis was performed which led to resolution of the continuous pneumothorax within four hours of therapy.

Autologous Blood Pleurodesis: What Is the Optimal Time Interval and Amount of Blood?

Air leak is the most common complication after lung resection and leads to increased length of hospital (LOH) stay or patient discharge with a chest tube. Management by autologous blood patch pleurodesis (ABPP) is controversial because few studies exist, and the technique has yet to be standardized. We retrospectively reviewed patients undergoing ABPP for prolonged air leak (PAL) following lobectomy in three centers, between January 2014 and December 2019. They were divided into two groups: Group A, 120 mL of blood infused; Group B, 60 mL. Propensity score-matched (PSM) analysis was performed, and 23 patients were included in each group. Numbers and success rates of blood patch, time to cessation of air leak, time to chest tube removal, reoperation, LOH, and complications were examined. Univariate and multivariate analysis of variables associated with an increased risk of air leak was performed. After the PSM, 120 mL of blood is statistically significant in reducing the number of days before chest tube removal after ABPP (2.78 vs. 4.35), LOH after ABPP (3.78 vs. 10.00), and LOH (8.78 vs. 15.17). Complications (0 vs. 4) and hours until air leak cessation (6.83 vs. 3.91, range 1-13) after ABPP were also statistically different (p < 0.05). Air leaks that persisted for up to 13 hours required another ABPP. No patient had re-operation or long-term complications related to pleurodesis. In our experience, 120 mL is the optimal amount of blood and the procedure can be repeated every 24 hours with the chest tube clamped.

Early use of autologous blood patch pleurodesis in children is successful in resolving persistent air leaks

Experience with autologous blood patch (ABP) pleurodesis for persistent air leak in the pediatric population is limited. The purpose of this series was to describe the experience with ABP at a single tertiary children's hospital. A retrospective study was performed of all thoracic procedures done by the pediatric surgery service over three years. Ten patients underwent a total of 17 ABPs. The median age of patients was 12 years (IQR 6-16). The most common underlying reasons for a thoracic procedure included: blebectomy for spontaneous pneumothorax (2), need for lung biopsy (2), resection of known malignant tumor (2), and empyema (2). The median number of days of persistent air leak before first ABP was 7.5 days (IQR 7-10). A second ABP was performed in 6 cases with a third procedure performed in one case. None of the patients developed respiratory compromise during ABP and no infectious complications were identified following ABP. Our cohort demonstrates that ABP for persistent air leak following thoracic surgery is effective with minimal morbidity in children. We believe ABP can be used early and in patients with a broad range of underlying lung pathology.

Application of autologous blood patch in patients with non-expanded lungs and persistent air leak.

This study aims to evaluate the effectiveness of pleurodesis procedure by ensuring the expansion of the lung and occluding lung parenchyma leaks with an autologous blood patch. A total of 24 patients (17 males, 7 females; mean age 59.9±12.2 years; range, 30 to 86 years) who underwent autologous blood patch pleurodesis in our clinic between November 2015 and November 2019 were retrospectively analyzed. The patients were not eligible to undergo chemical pleurodesis due to a nonexpandable lung or poor general condition. Demographic and clinical characteristics of the patients and postoperative data were evaluated. The air leak stopped within 48 h after autologous blood patch pleurodesis in seven patients. The air leak significantly decreased in 13 patients, while it remained unchanged in four patients. A Heimlich valve was placed in the patients in whom the air leak stopped or significantly decreased. The follow-up chest X-rays showed that the respective lungs of these patients became completely expandable. Our study results suggest that the autologous blood patch procedure is a favorable option for the patients who are unable to benefit much from the conventional chemical pleurodesis methods due to contraindications to surgery or the presence of non-expandable lungs.

A Prospective Study Investigating Blood Patch Pleurodesis for Postoperative Air Leaks After Pulmonary Resection

BackgroundProlonged air leaks (PALs) after lung resection are one of the most common complications in thoracic surgery. Several options are available to treat PALs. The autologous blood patch pleurodesis is commonly used but has not been thoroughly investigated. Materials and methodsWe conducted a prospective randomized study including all consecutive patients with PALs after pulmonary resections. Patients were randomized to either having received pleurodesis by injecting 100 mL autologous blood at d 5 and 6 (Group A) or being placed under observation (Group B). Patients from either group undergoing revisions were further investigated by a post hoc analysis and formed Group C. ResultsA total of 24 patients were included: 10 patients were randomized to group A and 14 to group B. Six patients (3 from each group) underwent surgical revision and were included in Group C. Groups A and B did not differ in baseline characteristics. The median time to drainage removal was 9 d (range: 5-23 d) in Group A; 9 d (range: 2-20 d) in Group B; and 6 d in Group C (range: 3-10 d), (A/B versus C, P < 0.04; A versus B was not significant). ConclusionsThere is no evidence indicating a benefit for blood patch pleurodeses in patients undergoing lung resections and presenting with postoperative PALs for more than 5 d. An early operative closure of postoperative air leakage seems to be more effective.

Dataset of a study investigating autologous blood patch pleurodesis in postoperative prolonged air leaks after lung resection.

Prolonged air leak (PAL) after pulmonary resection is one if the most common complications in thoracic surgery. The dataset was obtained from a prospective randomized study investigating autologous blood patch pleurodesis in PAL. Patients were randomized to either receiving 100 ml autologous blood injected at postoperative days five and six (group A) or to watchful waiting (group B). The primary and secondary endpoints focused on differences in the duration of PAL in each group and possible complications. The results were reported in The Journal of Surgical Research. In this Data in Brief article, we provide additional data concerning pain medication and pain score during the first ten postoperative days. This should provide additional insights into the trial.

The effectiveness of blood amount used in pleurodesis to prevent prolonged air leakage.

This study aims to investigate the effects of different amounts of blood used in autologous blood patch pleurodesis on clinical outcomes in patients with secondary spontaneous pneumothorax. Between January 2015 and April 2019, a total of 42 patients (36 males, 6 females; mean age 52.1±16.0 years; range, 25 to 83 years) with SSP treated in our clinic with persistent air leakage for more than seven days were retrospectively analyzed. The patients were divided into two groups as receiving 60 mL autologous blood patch pleurodesis (Group 1, n=20) and 120 mL autologous blood patch pleurodesis (Group 2, n=22). Data including age, gender, operation side, complications, recurrence rates, time to tube withdrawal, and length of hospital stay were recorded and compared between the groups. The mean duration of air leakage was 3.3±2.4 (range, 1 to 11) days, the mean number of pleurodesis was 1.6±0.7 (range, 1 to 3), the mean time to tube withdrawal was 5.2±3.3 (range, 1 to 16) days, the mean length of hospitalization was 7.1±3.6 (range, 3 to 18) days. There were statistically significant differences in all variables analyzed between Group 1 and Group 2 (p<0.001). Autologous blood patch pleurodesis is an effective and safe method in the treatment of prolonged air leakage in secondary spontaneous pneumothorax. In addition, 120 mL of blood seems to be more effective option for pleurodesis.
