Aortic pseudoaneurysm is a rare, life-threatening complication after cardiac or aortic root surgery. When a pseudoaneurysm has eroded bony structures in the chest, the surgeon's challenge is to choose the safest approach for sternotomy. Herein, we report the case of a 74-year-old woman who presented with a giant pseudoaneurysm of the ascending aorta, 8 years after undergoing aortic valve replacement. ⋯ A new aortic valved tissue conduit was placed, and the coronary arteries were reimplanted. The patient recovered without neurologic sequelae. We discuss the characteristics of this case and explain our surgical decisions.

Patent foramen ovale is increasingly diagnosed in patients who are undergoing clinical study for cryptogenic stroke or migraine. In addition, patent foramen ovale is often suspected as a cause of paradoxical embolism in patients who present with arterial thromboembolism. The femoral venous approach to closure has been the mainstay. ⋯ Herein, we describe 2 cases of patent foramen ovale in which the transhepatic approach was used for closure. To our knowledge, this is the 1st report of a transhepatic approach to patent foramen ovale closure in an adult patient. Moreover, no previous case of patent foramen ovale closure has been reported in a patient with interrupted inferior vena cava.

Interatrial septal hematoma is a very rare complication after mitral valve surgery. Unusually, it is the result of aortic valve disease, including aortic dissection. We report a case wherein interatrial septal hematoma followed minimally invasive aortic valve replacement in a 68-year-old woman. ⋯ The interatrial septal hematoma was at first drained by needle, but recurrence prompted reoperation and plication of the interatrial septum. Finally, the hematoma resolved after correction of the coagulopathy. Catheter injury to the coronary sinus exacerbated by the retrograde administration of cardioplegic solution is thought to have caused the origin of the interatrial septal dissection.

Case Reports
Pericardial tamponade and right-to-left shunt through patent foramen ovale after epicardial pacing-wire removal.
After cardiac operations, careful management substantially reduces the risks of negative complications during or after the removal of temporary epicardial pacing wires. Herein, we report the case of a 58-year-old man who, 4 days after undergoing aortic root replacement, developed pericardial tamponade after the removal of temporary epicardial pacing wires. Consequent to the tamponade, a right-to-left shunt developed through a previously undiagnosed patent foramen ovale. The patient underwent emergency surgery to repair myocardium that had ruptured due to the removal of the wires, and he recovered uneventfully.

During carotid endarterectomy, the use of locoregional anesthesia to achieve a combined superficial and deep cervical plexus block can cause cardiovascular, respiratory, and neurologic complications. Seeking to reduce risk and find an easier procedure, we applied locoregional anesthesia and an intermediate cervical plexus block in a series of patients who underwent carotid endarterectomy. From 2006 through 2007, 183 patients underwent primary carotid endarterectomy at our hospital. ⋯ Postoperatively, 2 patients experienced strokes and 1 sustained a myocardial infarction (total rate, 1.6%). We found the intermediate cervical plexus block to be feasible, effective, and safe, with low perioperative and postoperative complication rates. Herein, we report our findings.
