About Inferior vena cava interruption without azygos continuation

What is Inferior vena cava interruption without azygos continuation?

Inferior vena cava interruption without azygos continuation is a surgical procedure used to treat deep vein thrombosis (DVT). It involves the interruption of the inferior vena cava (IVC), the largest vein in the body, which carries deoxygenated blood from the lower body back to the heart. The interruption is done without azygos continuation, meaning that the azygos vein, which is a small vein that runs along the spine, is not used to bypass the IVC. This procedure is used to prevent further clotting and reduce the risk of pulmonary embolism.

What are the symptoms of Inferior vena cava interruption without azygos continuation?

The symptoms of inferior vena cava interruption without azygos continuation can include:

- Swelling of the legs, ankles, and feet
- Abdominal swelling
- Shortness of breath
- Fatigue
- Palpitations
- Chest pain
- Lightheadedness
- Low blood pressure
- Increased heart rate
- Dark urine
- Jaundice
- Abdominal pain
- Nausea and vomiting

What are the causes of Inferior vena cava interruption without azygos continuation?

1. Congenital anomalies such as azygos vein hypoplasia or agenesis.
2. Trauma or iatrogenic injury to the inferior vena cava.
3. Tumor invasion of the inferior vena cava.
4. Congenital heart defects such as atrial septal defect or ventricular septal defect.
5. Congenital malformations of the thoracic aorta.
6. Congenital malformations of the abdominal aorta.
7. Congenital malformations of the renal veins.
8. Congenital malformations of the hepatic veins.
9. Congenital malformations of the portal vein.
10. Congenital malformations of the inferior vena cava.

What are the treatments for Inferior vena cava interruption without azygos continuation?

1. Open surgical repair: This is the most common treatment for IVC interruption without azygos continuation. The surgeon will make an incision in the abdomen and repair the IVC using sutures or a patch.

2. Endovascular repair: This is a minimally invasive procedure that involves inserting a catheter into the IVC and using a stent to repair the interruption.

3. Transjugular intrahepatic portosystemic shunt (TIPS): This procedure involves creating a shunt between the portal vein and the hepatic vein to bypass the interruption in the IVC.

4. Extracorporeal membrane oxygenation (ECMO): This is a life-saving procedure that involves using a machine to oxygenate the blood outside of the body. It is used in cases where other treatments are
