Internal carotid artery stenting for blunt carotid artery injuries with an associated pseudoaneurysm.

Background: Blunt carotid artery injuries (BCI) are being recognized and treated with increasing frequency because of improved screening protocols. Recent advances in endovascular techniques using microcoils, angioplasty, and stenting offer a new treatment strategy for those patients with traumatic pseudoaneurysms (PA) (BCI and PA). Experience with these techniques is limited because of the rarity of these injuries.

Empyema necessitatis in an infant: a rare surgical disease.

Empyema necessitatis is a rare complication of empyema and is more commonly reported in adults. It is characterized by purulence in the pleural space extending into the overlying soft tissues. We report a rare case in an otherwise healthy 3-month-old girl who presented with right chest wall swelling and was subsequently found to have methicillin-resistant Staphylococcus aureus empyema necessitatis requiring thoracotomy with decortication.

Sixteen-slice multi-detector computed tomographic angiography improves the accuracy of screening for blunt cerebrovascular injury.

Background: Blunt cerebrovascular injuries (BCVI) are rare but potentially devastating injuries, particularly if the diagnosis is delayed. Only four-vessel cerebral angiography (FVCA) has been shown to be adequately sensitive and specific as a screening tool for BCVI but is resource-intensive and invasive. Computed tomography (CT) angiography has emerged as a possible alternative, but its accuracy has been poor, particularly for low-grade injuries.
