Cryoablation of cardiophrenic angle lymph node metastases: a case report

Abstract

BackgroundCardiophrenic angle lymph node metastases are relatively rare. Surgical resection is the main treatment for cardiophrenic angle lymph node metastasis, but it is not always possible.Case presentationHere, we report our initial experience with cryoablation of a cardiophrenic angle lymph node metastasis from liver cancer. As the cardiophrenic angle lymph node metastasis was located close to the heart, about 200 mL of 0.9% saline was injected into the pericardium to separate the heart from the target area. The cardiophrenic angle lymph node metastasis was successfully ablated, without any complications.ConclusionsCryoablation may be a suitable alternative treatment for cardiophrenic angle lymph node metastasis.
