Insights
A rare case of abnormal blood flow from the inferior vena cava to the left atrium was successfully treated. This unusual congenital heart defect required Doppler ultrasound and angiography for diagnosis and surgical correction.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Surgical Innovation
Background:
- Ectopic drainage from the inferior vena cava to the left atrium is a rare congenital anomaly.
- Partial anomalous pulmonary venous drainage can coexist with other cardiac malformations.
Observation:
- A 44-year-old male presented with symptoms indicative of an unusual cardiac drainage pattern.
- Diagnosis was confirmed using Doppler echocardiography and angiography, revealing inferior vena cava to left atrium drainage and partial anomalous pulmonary venous drainage.
Findings:
- Surgical correction was performed using a pericardial patch to reroute blood flow to the atrium.
- The patient experienced a successful surgical outcome and initiated rehabilitation 8 days post-operation.
Implications:
- This case highlights the importance of advanced imaging techniques like Doppler ultrasound and angiography for diagnosing rare cardiac anomalies.
- Successful surgical intervention demonstrates the feasibility of correcting complex congenital heart defects.
- Further research into the long-term outcomes of such rare conditions is warranted.
Abstract:
We report a case of a 44-year-old male patient with ectopic drainage from the inferior vena cava to the left atrium accompanied by partial anomalous pulmonary venous drainage. After the patient was hospitalized, his diagnosis was confirmed by Doppler echocardiography and angiography. A pericardial patch was used to divert the blood to the atrium. The surgical procedure was successful, and the patient began a rehabilitation program 8 days later. This type of ectopic drainage pattern is an unusual and infrequent clinical finding. The definitive diagnosis should be made by Doppler ultrasound combined with angiography.

Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
