He underwent coil embolization of hepatic artery pseudo-aneurysm. The pseudo-aneurysm was successfully obstructed and subphrenic liver abscess was controlled. Super-selective trans-catheter coil embolization may represent an effective treatment for hepatic artery pseudo-aneurysm combined with subphrenic liver abscess in the absence of other therapeutic alternatives.展开更多

Only two cases secondary to spinal trauma and revealed after surgery have been described in the literature. A review of literature was conducted and a possible relationship with burst fracture or reduction maneuvers was discussed. <strong>Case Presentation:</strong> Here, we report a post traumatic lumbar burst facture with incomplete motor deficit of lower limbs after a fall. Surgical reduction and stabilization via posterior approach were performed. Post-operatively, a hemorrhage through surgical wound had been noticed. Pseudo-aneurysm of the lumbar artery at L3 level was diagnosed and embolisation was performed. <strong>Conclusion:</strong> This is a rare case of pseudo-aneurysm occurring in the setting of surgical stabilisation after a trauma. It was revealed by a hemorrhage discovered as a late complication. We should be aware of such potential complication as a delayed post surgery event in order to adapt the care.展开更多

Most CCFs have direct high flow. Clinical presentations primarily depend on the pressure inside the cavernous sinus and on the direction of the venous drainage. The ideal goal for the treatment of direct CCF is the obliteration of the fistula while preserving the internal carotid artery （ICA）. Transarterial embolization of direct CCF with detachable balloons has been proven to be the best option for an initial treatment, although transarterial embolization by detachable balloons is frequently associated with pseudo-aneurysm formation. Many treatment options such as coiling, stent-assisted coiling, and covered stent have been proposed to treat pseudo-aneurysm. However, the best management for a pseudo-aneurysm occurring after an embolization of a CCF with detachable balloons remains unknown. In this article, we will report our successful attempt in treating the said pseudo-aneurysm. We initially dealt with a pseudo-aneurysm occurring after an embolization of a CCF with stent-assisted coiling; then, the pseudoaneurysm recanalized, and eventually a covered stent was placed for the recanalized pseudoaneurysm.展开更多
