Spontaneous lumbar artery rupture and massive retroperitoneal hematoma, successfully treated with arteriographic embolization.

BACKGROUND AND OBJECTIVE

Massive retroperitoneal hematoma caused by lumbar artery rupture is generally associated with trauma or retroperitoneal malignancy. However, despite recent advances in technologies and tools, spontaneous lumbar artery rupture is a very rare disease entity but remains a challenging problem because it is frequently associated with significantly high mortality and morbidity and is very difficult to make a correct diagnosis.

METHODS

We evaluated the databases of the PubMed, Embase, Cochrane Central Register of Controlled Trial, Google Scholar, the KoreaMed and the Research Information Sharing Service databases, and a detailed systematic review was performed by searching in PubMed. The initial search was performed on 3 February 2018 and a second search conducted in 29 January 2019.

RESULTS

A total of 10 case reports on massive hemoperitoneum caused by spontaneous lumbar artery rupture were identified. Of the 10 case reports involving 14 patients, eight were male and six were female under 62.71 ± 13.93. Of the 14 patients, 9 (64.3%) surviving with transcatheter arterial embolization, three (21.4%) died of multi-organ failure or hypovolemia, and two (14.3%) had no definite records on survival or death.

CONCLUSIONS

A massive retroperitoneal hematoma caused by lumbar artery rupture should be considered in patients with late-onset shock accompanied by blunt abdominal/pelvic trauma. Furthermore, early detection and urgent embolization would prevent further complications and eliminate the need for surgical interventions.
