Pneumopericardium is an infrequent complication of PPDH. This condition is a serious circumstance in which free gas accumulates in the pericardial sac. The present report describes the occurrence of pneumopericardium and pericardial effusion after elective ovariectomy in a dog affected by PPDH. The presence of an umbilical and diaphragmatic hernia was highlighted during ovariectomy, and a pneumopericardium was seen during an X-ray exam. At the time of admission to the hospital, the dog was asymptomatic. The diagnosis was performed by X-ray and ultrasonographic exams. Computed tomography examination confirmed the diagnosis and directed for a surgical approach of the congenital defect. Surgery resulted in resolution of PPDH and of pneumopericardium.<\/jats:p>","DOI":"10.3390\/ani14040633","type":"journal-article","created":{"date-parts":[[2024,2,16]],"date-time":"2024-02-16T06:00:25Z","timestamp":1708063225000},"page":"633","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Evidence of Pneumopericardium after Elective Ovariectomy in a Peritoneopericardial Diaphragmatic Hernia-Affected Dog: A Case Report"],"prefix":"10.3390","volume":"14","author":[{"given":"Debora","family":"Campanile","sequence":"first","affiliation":[{"name":"Ospedale Veterinario Atheryon, via Grecia, 2, 76125 Trani, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariateresa","family":"Cafaro","sequence":"additional","affiliation":[{"name":"Ospedale Veterinario Atheryon, via Grecia, 2, 76125 Trani, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7563-2219","authenticated-orcid":false,"given":"Serena","family":"Paci","sequence":"additional","affiliation":[{"name":"Ospedale Veterinario Atheryon, via Grecia, 2, 76125 Trani, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michele","family":"Panarese","sequence":"additional","affiliation":[{"name":"Ospedale Veterinario Atheryon, via Grecia, 2, 76125 Trani, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giammarino","family":"Sparapano","sequence":"additional","affiliation":[{"name":"Ospedale Veterinario Atheryon, via Grecia, 2, 76125 Trani, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Masi","sequence":"additional","affiliation":[{"name":"Clinica Veterinaria Polispecialistica Associata, via Parco del Lauro, 72, 70044 Polignano a Mare, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"De Simone","sequence":"additional","affiliation":[{"name":"Ospedale Veterinario Atheryon, via Grecia, 2, 76125 Trani, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,16]]},"reference":[{"key":"ref_1","first-page":"94","article-title":"Pneumopericardium associated with peritoneal pericardial diaphragmatic hernia repair in a dog","volume":"110","author":"Papazoglou","year":"2015","journal-title":"J.
