Comparative StudyDifferences in the recovery of platelet counts after biological aortic valve replacement.
Observations among Karlsburg patients in 2006 revealed that the majority of very low platelet levels inducing postoperative heparin-induced-thrombocytopenia (HIT)-diagnostics with at the end negative results appeared related to aortic valve replacement (AVR) with stentless bioprostheses. We compared the postoperative courses of platelet counts in patients having had AVR with stentless prostheses (Sorin Biomedica Freedom Solo [SOLO]) or stented prostheses (Carpentier Edwards Perimount [PM]). Between February 2005 and April 2007, 209 patients received AVR with SOLO, in 137 patients a PM-prosthesis was implanted. ⋯ Differences in platelet counts between SOLO- and PM-subgroups were measured for day 2 (P=0.03), day 3 (P=0.0004) day 4 (P=0.0007), day 5 (P=0.0002) and at discharge (P<0.0001). Following intervention with conventional biological AVR, differences in the postoperative recovery of platelet counts can be detected, depending on the prosthesis used. The causes for and the clinical implications of this phenomenon are not yet assessed.

Case ReportsSuccessful angiographic embolisation of bleeding into the chest wall after chest drain insertion.
Peripheral arterial injuries after blunt or penetrating trauma commonly follow injuries to adjacent soft tissue and bone. The traditional approach to these injuries is by open exploration, with identification and ligation of the bleeding vessel. We describe the case of a type II respiratory failure patient who had an enormous pectoral muscle haematoma following chest drain insertion, in whom the bleeding was only controlled by angiographic embolisation following failure of surgical exploration.

Case ReportsVenovenous extracorporeal membrane oxygenation support for treatment of bilateral spontaneous pneumothorax.
Bilateral spontaneous pneumothorax is a rare but serious cause of respiratory distress. We treated a 77-year-old male with severe hypoxia caused by bilateral spontaneous pneumothorax using video-assisted thoracoscopic bullectomy assisted by a venovenous extracorporeal membrane oxygenation (ECMO) device. The patient came to the emergency department of our hospital with complaints of cough and dyspnea, and was hospitalized with right-side spontaneous pneumothorax and left-side pneumonia. ⋯ A chest tube was inserted into the left pleural cavity, and surgery was performed for bilateral pneumothorax by video-assisted thoracoscopic surgery (VATS) assisted by venovenous ECMO. Gas exchange was satisfactory throughout the surgical procedure and the postoperative course was uneventful without complications. Venovenous ECMO was effective for facilitation of VATS and reduced the risk of an intra-operative hypoxic condition.
