SANCHEZ HERNANDEZ, Cristina et al. Spontaneous paravesical hematoma at a single prophylactic doses of enoxaparin in Orthopedic surgery. Case report. Medisur [online]. 2016, vol.14, n.5, pp. 573-578. ISSN 1727-897X.

Spontaneous paravesical hematoma is an infrequent complication, with a few reported cases in literature. Approximately 2 % of the patients treated with prophylactic enoxoparin will have hemorrhagic complications, from which 2 0% are retroperitoneal or intracranial hematomas depending on the risk factors. For such reasons it is presented a 35 year old patient, previously healthy, who was performed to a suture of the Achilles tendon after suffering a trauma. He was administered prophylactically a single doses of enoxoparin in the immediate post surgery and 24 hours later he started to complain of pain in the right lower quadrant and dysuria. Abdominal ultrasound showed a paravesical hematoma secondary to anesthesia which caused bleeding of the vesicle walls. This report shows prophylactic exoparin may produce spontaneous paravesical hematomas associated to vesical overdistention. However it is necessary other similar reports to confirm the previous statement.
