Iatrogenic Pseudoaneurysm

Pseudoaneurysm (PSA) formation is the most common arterial complication of endovascular procedures requiring arterial puncture. The present study reported a case of a 72-year-old male patient with iatrogenic femoral artery PSA treated with contrast-enhanced ultrasound (CEUS) - guided thrombin injection. Conventional ultrasound (US) and CEUS were used to diagnose, guide treatment, and evaluate the treatment efficacy. In the case, the PSA was successfully occluded with 1000 IU of thrombin. During the follow-up after 48 hours of thrombin injection, US found that the PSA had complete thrombosis without arterial supply. No complications occurrence in the course of the treatment. CEUS - guided thrombin injection for the treatment of PSA was effective and safety and the associated literatures were also reviewed.

Aims: To assess contrast enhanced ultrasound (CEUS) performance in the prediction of non-operatively managed blunt spleen injuries requiring only observation and monitoring during follow-up and to evaluate if CEUS accuracy was higher than conventional ultrasound (US) in this field.Material and methods: In 112 hemodynamic stable blunt spleen trauma patients, CEUS was performed for follow-up after computed tomography evaluation in the emergency department. CEUS and US performance were assessed considering as true negative cases patients that had not underwent interventional or surgical treatment during follow-up and were assessed as negative for splenic complications respectively by CEUS or US examinations.Results: CEUS showed sensitivity of 100%, specificity of 96.1%, positive predictive value of 69.2%, negative predictive value of 100.0% and accuracy of 96.4%. CEUS showed a significantly higher accuracy than conventional US (p=0.013).Conclusions: CEUS is a very useful imaging modality during follow-up of blunt splenic trauma non-operatively managed, allowing an efficientprediction of splenic injuries requiring only observation and monitoring during follow-up.

Objective. To discuss the clinical application value of contrast-enhanced ultrasound (CEUS) in testicular occupied lesions. Methods. Nine conventional-ultrasound-found testicular occupied lesions which underwent CEUS meantime were analyzed retrospectively. The CEUS perfusion pattern was compared with the surgical pathological result or follow-up findings. Results. Among all the 9 testicular occupied lesions, there were 5 testicular malignant tumors, 1 testicular benign tumor, 1 testicular tuberculosis, and 2 testicular hematomas. CEUS diagnosed 6 testicular malignant tumors, 1 testicular benign tumor, and 2 testicular hematomas, and its diagnostic accuracy was about 88.9%. Conclusion. CEUS has high clinical application value in the differential diagnoses of benign and malignant testicular occupied lesions.
