## Frequently asked questions

### Does DVT always cause symptoms?

Not always. Some thromboses may cause subtle symptoms or even go unnoticed. That is why, when there is clinical suspicion or important risk factors, an imaging test may be necessary.

### Is DVT the same as phlebitis?

Not exactly. The term “phlebitis” has been used very broadly for years, but it can cause confusion. It is more precise to distinguish between superficial vein thrombosis and deep vein thrombosis, because their severity, treatment and consequences can be very different.

### Can thrombosis be cured?

In many cases, treatment can control the condition, prevent the thrombus from progressing and help the body gradually resolve it. However, the vein may be left with sequelae, especially if its valves are damaged. That is why follow-up is important.

### Which is more dangerous: the clot in the leg or if it reaches the lung?

DVT is already important in itself, but the most feared immediate complication is that part of the thrombus breaks off and causes a pulmonary embolism, which can become very serious. This is one of the reasons why early diagnosis is so relevant.

### Can I walk if I have a thrombosis?

In many cases, once it has been diagnosed and treated, progressive mobilisation is recommended and absolute bed rest should be avoided. But this indication must be given by the doctor according to the extent of the thrombosis, the symptoms and the individual risk.

### Can post-phlebitic syndrome be prevented?

It cannot always be completely prevented, but early diagnosis, appropriate treatment, compression when indicated, mobility, weight control and vascular follow-up may help reduce its consequences.
