Long-term follow-up of adventitial cyst surgical excision in external iliac vein

Adventitial cystic disease of the venous system is an extremely rare condition. Forty-five cases have been described in the literature during the last 70 years, but they may not be representative of the real incidence of this pathologic process. We report a case of an adventitial cyst compressing the right external iliac vein and presenting with edema of the ipsilateral leg. Ultrasound imaging and computed tomography angiography showed the typical features of cystic disease and venous stenosis. Cyst excision was performed with a double surgical access. No perioperative complications were reported. There was no recurrence at 4-year follow-up

Intraoperative immunomodulation during left heart bypass in open thoracoabdominal aortic aneurysm repair

Despite the technical innovations introduced in the previous decades, open thoracoabdominal aortic aneurysm repair still represents an enormous challenge for patients and surgeons. Logically, the systemic inflammatory response resulting from these massive operations appears considerable; however, the response has never been thoroughly investigated. In addition, intraoperative adjuncts to modulate the postoperative activation of the immune system have not yet been introduced into clinical practice. We report a case of intraoperative hemadsorption during open repair of a thoracoabdominal aortic aneurysm through the introduction of a CytoSorb device (CytoSorbents Corp) in the left heart bypass circuit. The technique appeared feasible and safe and probably contributed to the good clinical outcomes
