Learning objectives

To describe what vascular compression syndromes consist of. To know the radiographic findings of each syndrome To determine the role of imaging tests in the diagnosis of this pathology, especially the findings in doppler ultrasound.

Background

Vascular compression syndromes consist of the trapping of a vessel in an anatomical space reduced by another structure. The manifestations are varied depending on the affected structure, being the diagnosis a combination of clinical manifestations and the findings by imaging test, being important to know them for the adequate diagnostic confrontation in this type of patients.[1] Vascular compression syndromes are a heterogeneous group of pathologies, depending on the compressed structure. Some of them are: Nutcracker syndrome Median arcuate ligament syndrome Thoracic outlet syndrome Popliteal artery...

Findings and procedure details

Nutcracker syndrome: Nutcracker syndrome involves compression of the left renal vein between the abdominal aorta and the upper mesenteric artery.[2] . In cases of retroaortic and circumaortic renal vein, it is sometimes observed between the aorta and the spine. The prevalence of nutcracker syndrome is unknown, and it is estimated that it may be higher in women. The age range in which it can occur is from children, to middle-aged people and even cases have been described in the seventh decade of life. There is...

Conclusion

Doppler ultrasound is useful in the diagnostic approach, because it is a dynamic, non-invasive study, among other advantages, allowing to estimate the need to complete the study through other tests. The radiologist must know the radiographic features, which may affect the diagnostic and therapeutic management, as well as post-treatment follow-up.
