Question:

Which of the following answer about azigos is false?
1. The azigos vein thrombosis is Hypertrophy in all the patients with a porth a cath catheters.
2. the azigos vein could be hypertrothy after cava vein thrombosis
3. Recognition of hypertrophic azygos vein, secondary to superior vena cava thrombosis, is very easy to be found in the literature
4. The pictures showed a clear alteration of the circle as well as a significant hypotrophy
5. Test performed in 2005 revealed the presence of an azygos hypertrophic in spite of a SVC that had a considerably reduced calibre





Answer:

The correct answers for the question "Which of the following answer about azigos is false?" are:

2. the azigos vein could be hypertrothy after cava vein thrombosis

4. The pictures showed a clear alteration of the circle as well as a significant hypotrophy

5. Test performed in 2005 revealed the presence of an azygos hypertrophic in spite of a SVC that had a considerably reduced calibre



Explanation

1. The obstruction of CVC develops progressively thrombosis of SVC (the Hypertrophy of azigos vein is secondary to thrombosis .)

2. the azigos vein is hypertrophic as compensatory system.(this must guarantee right flow in vessels.)

3. This recognition is not frequent.( This phenomenon will develop in many years)

4. The pictures show an alteration of collateral circle forming.(This phenomenon is present in all the pictures)

5. This is the end of process of compensatory circle (the two veins had a different caliber from the anatomic system)

Compensatory dilatation of the Azygos Venous system Secondary To Superior Vena Cava Occlusion

Abstract
Superior vena cava (SVC) occlusion can be clinically recognized in the acute setting when the stenosing process does not allow the development of collateral venous channels, which guarantee the venous drainage to the right heart. On the contrary, when the obstruction develops progressively, the diagnosis of SVC obstruction may remain undiagnosed. In the present case, the presence of SVC thrombosis was purely coincidental. In fact, the obstruction was first noticed on diagnostic tests performed because of the malfunction of a totally implantable Porth a Cath placed into the superior vena cava (through right subclavian access), five years before, in a patient suffering from non-Hodgkin disease. Venography is the most appropriate diagnostic methodology which reveals the presence of a dilated azygos vein as a compensatory mechanism. Comparison with computed tomography allows to confirm the diagnosis and to identify the possible causes. Dilatation of the azygos vein, secondary to superior vena cava thrombosis, although a rare event, should be taken into consideration in those patients with CVC and who present with frequent episodes of deep venous thrombosis.
