【Sinus Venosus ASD & PAPVC in Dogs】
当センターでCT血管造影により診断した洞静脈型心房中隔欠損(SVASD)と部分的肺静脈還流異常(PAPVC)を有する犬10頭の所見をまとめた報告がJournal of Veterinary Cardiologyに掲載されました!
🔎研究のポイント
- 全例で右心系の拡大が認められ、SVASDは心エコーで7頭で描出可能、CTで全例に確認
- PAPVCは全例に存在し、流入部位は右心房・前大静脈-右心房接合部・前大静脈に分類
- 9頭で体外循環下で外科的修復を実施し、術後チェックで右心サイズ減少
- CT血管造影は診断・手術計画において有用
New paper out!!
We summarized the clinical, echocardiographic, and CT findings of 10 dogs diagnosed with sinus venosus atrial septal defect (SVASD) and partial anomalous pulmonary venous connection (PAPVC), now published in the Journal of Veterinary Cardiology.
🔍 Key points
- All dogs showed right heart enlargement; SVASD detected in 7 dogs by echocardiography and in all dogs by CT
- PAPVC confirmed in all cases with drainage into the RA, CrVC-RA junction, or CrVC
- 9 dogs underwent cardiopulmonary bypass surgery with a trend toward decreased right heart size at 3-month follow-up
- CT angiography proved valuable for diagnosis and surgical planning
