Acute hydrothorax in a peritoneal dialysis patient: long-term efficacy of autologous blood cell pleurodesis associated with small-volume peritoneal exchanges

Successful treatment of pleuroperitoneal communication with pleurodesis using autologous blood in a patient with severe heart failure undergoing peritoneal dialysis: a case report and brief literature review

Background

Pleuroperitoneal communication is a potential complication of peritoneal dialysis (PD). Of the various treatment strategies for pleuroperitoneal communication, successful treatment with pleurodesis using autologous blood has rarely been reported.

Case presentation

A 58-year-old man with end-stage kidney disease secondary to diabetic nephropathy and severe heart failure was placed on PD. He developed right-sided hydrothorax after the commencement of PD. Technetium-99m macro-aggregated human serum albumin peritoneal scintigraphy revealed pleuroperitoneal communication. PD was temporarily discontinued and substituted with hemodialysis. Subsequently, the levels of pleural fluid decreased. However, the resumption of PD exacerbated the hydrothorax. After thoracentesis, 50 mL of autologous blood was instilled into the right pleural cavity. There were no complications related to the procedure. PD was reinitiated 5 days after pleurodesis. Repeated chest X-rays did not depict any evidence of recurrent hydrothorax over the subsequent 10 months.

Conclusions

Pleurodesis using autologous blood was effective for pleuroperitoneal communication and was evidently safe in our patient. It should be considered in patients with severe heart failure since it is minimally invasive.

Acute Hydrothorax Complicating Peritoneal Dialysis

Aim

To determine whether gradually increasing the peritoneal dialysate fill volume from 10 to 40 mL/kg over 6 days, rather than commencing at 40 mL/kg, prevents hydrothorax in children and reverses it if present.

Methods

A review of children peritoneally dialyzed in a single center.

Results

During the 20 years beginning June 1985, 416 children were peritoneally dialyzed, of which 327 (79%) had acute and 89 had end-stage renal failure. Among 253 children who had gradually increasing fill volumes, none developed acute hydrothoraces, but 13/163 (8%) who began with 40 mL/kg cycles did ( p < 0.000, Fisher's exact test). These were diagnosed after a median (range) of 48 (6 – 72) hours and were predominantly right sided. Initially, we readily abandoned peritoneal dialysis; 2 were changed to hemodialysis. Subsequently, we found that peritoneal dialysis could be continued by using small volumes with the patients sitting up; cycle volumes were then gradually increased again. One pre-term baby died soon after developing an acute hydrothorax. One patient on chronic peritoneal dialysis developed an acute hydrothorax after forceful vomiting, but recovered after being dialyzed sitting up with low fills.

Conclusion

Acute hydrothorax can be prevented and treated using graduated cycle volumes, and is not a contraindication for peritoneal dialysis.

Blood patch for persistent air leak: a review of the current literature

PURPOSE OF REVIEW

Persistent air leak (PAL) poses a significant challenge to the thoracic surgeon. Of the numerous methods employed to manage this problem, autologous blood 'patch' pleurodesis (ABPP) remains one of the most controversial, seemingly due to a lack of robust data and consensus of opinion regarding its efficacy, technique of application and its role in clinical practice. Despite a lack of randomized control trials, the evidence to-date has shown ABPP to be an efficacious, cheap, simple, well tolerated and readily available treatment, with minimal side effects and broad range of applications, allowing for earlier chest drain removal, decreased complications and decreased hospital stay. A review is therefore required to assess the role for ABPP in contemporary clinical practice.

RECENT FINDINGS

Recent studies have demonstrated that ABPP is an effective management for PAL in specific patient groups and there is an argument that it has the potential to be the gold-standard or first-line treatment in certain clinical scenarios such as for patients with interstitial lung disease or acute respiratory distress syndrome.

SUMMARY

This review aims to discuss the relevance of recent findings and to suggest a firm role for ABPP in current practice. In addition, the evidence for the efficacy of ABPP will be assessed and compared with other established methods of pleurodesis. Finally, the review will include a summary of relevant research to-date in order to suggest an evidence-based standardized protocol for the application of ABPP.

Non-infectious complications of continuous ambulatory peritoneal dialysis and their impact on technique survival

Data on non-infectious complications of continuous ambulatory peritoneal dialysis (CAPD) are sparingly reported from different centres of the country. We studied the non-infectious complications in patients of end stage-renal disease (ESRD) undergoing CAPD. Double-cuffed straight catheter was inserted in all patients using the surgical method and CAPD was started on the 15^th day of catheter insertion. The nature of non-infectious complications was noted during follow-up in these patients. Forty-five (male 31, female 14) patients with the mean age of 54.5±11.6 years were studied. Diabetic nephropathy was the most common (59.5%) cause of ESRD. Overall, non-infectious complications were noted in 18/45 (40%) cases. Ultrafiltration failure was the most common (15.5%) followed by incisional hernia (6.6%), exit site leak (4.4%), hydrothorax (4.4%), catheter malposition (4.4%), scrotal swelling (2.2%) and hemoperitoneum (2.2%). Patients with ultrafiltration failure were either shifted to hemodialysis or underwent renal transplantation. The remaining (62%) non-infectious complications did not affect the catheter survival and CAPD could be continued. Non-infectious complications occurred in 40% of our CAPD patients and ultrafiltration failure was the most common (15.5%). A majority (62%) of the complications did not affect catheter survival.

Hydrothorax: pleural effusion associated with peritoneal dialysis

Hydrothorax in a patient treated with peritoneal dialysis (PD) poses a diagnostic dilemma. Hydrothorax due to migration of dialysis fluid across the diaphragm and into the pleural space creates a serious complication of PD but generally does not threaten life. Shortness of breath causes the patient to seek medical attention. A sudden diminution in dialysis adequacy or poor ultrafiltration rate constitutes a unique marker for patients treated with PD compared to the general population. This article reviews the etiology for hydrothorax specifically in the PD population. Thoracentesis with chemical analysis of the fluid, imaging studies with and without contrast or markers, and video-assisted thoracoscopic surgery play important roles in the evaluation of hydrothorax. A conservative PD regimen, surgical intervention, and pleurodesis provide treatment options to those receiving PD.
