| Abstract |
|
Out of 1617 cases of congenital heart disease, who were admitted to the Pediatric ward, Seoul National University Hospital, for cardiac catheterization during recent 5 years, 20 patients
with anomalous inferior vena cava were observed. Associated cardiac and extracardiac vascular anomalies were reviewed. Cardiac and visceral malposition were also analyzed. Results;
1) Incidence was 1.2% of total 1617 catheterized patients. 2) Male and female ratio was 8 : 12.
3) Age distribution by 5 years interval was as follows. 0〜5 years; 12 cases;5〜 10 years; 6 cases
10〜 15 years; 2 cases 4) Twelve cases of cardiac and visceral malposition were seen.
Asplenia was associated in 4 cases. Dextrocardia with situs inversus: 5 cases** Levocardia with situs inversus or ambiguus: 7 cases** 5) Associated cardiac anomalies;
Cyanotic C.H.D. 13 cases Acyanotic C.H.D.; 7 cases Single atrium 5 V.S.D. 5 Cor-biloculare 4 A.S.D. 2
Single ventricle 1 T.G.A. 1 T.O.F. 1 D.O.R.V, 1
6) In 3 cases, right mediastinal mass like shadow was observed. In lateral film, absence of LV.C. shadow below right atrium was recognized in 4 cases. 7) Arrhythmia, including 1 case of coronary sinus rhythm was noted on EKG in 7 cases 8) In 15 cases, the venous drainage was through azygos vein and in 5 cases through hemiazygos vein. 9) Persistent left superior vena cava was associated in 9 cases especially with hemiazygos continuation
(4 cases out of 5 patients with hemiazygos continuation). ****; 4 cases of asplenia
