# A case of native lung hyperinflation after single lung transplantation treated with lung volume reduction coils

## TL;DR

A patient with lung overinflation after a lung transplant was successfully treated using special coils that reduce lung volume.

## Contribution

This case demonstrates the safe use of lung volume reduction coils for hyperinflation in lung transplant recipients with collateral ventilation.

## Key findings

- Lung volume reduction coils were used to treat native lung hyperinflation after single lung transplantation.
- The treatment was effective and safe in a patient with collateral ventilation.
- This approach offers a new option for managing hyperinflation in such transplant recipients.

## Abstract

Single lung transplantation (SLTx) has been used to treat end-stage lung disease. A common complication after SLTx is hyperinflation of the native emphysematous lung (NLH). Previous attempts to reduce the NLH have been tried using surgery, endoscopic valves, etc. with variable outcomes. Lung volume reduction coils can be used for treating hyperinflation in emphysema patients irrespective of collateral ventilation (CV). We here report a case of native lung hyperinflation in SLTx treated with lung volume reduction coils. This treatment appears to be a safe treatment option when dealing with CV-positive NLH in SLTx recipients.
