To investigate and present the reasons that cause the postponement of thoracic surgical operations. We retrospectively included in the study all patients submitted to elective thoracic surgery in our department during the 4-year period 2007-2010 and noted all cases of postponement after official inclusion in the operating schedule. 81 out of a total of 542 patients (14.9%) scheduled for elective thoracic operation had their procedure postponed. The reasons were mainly organisatory (in 42 cases, 51.85%), which in order of significance were: shortage in matching erythrocyte units, shortage in anaesthetic/nursing staff and unavailability in operating rooms. The rest of the cases (39, 48.1%) were postponed due to medical reasons, which in descending order of significance were: respiratory infections and exacerbations of COPD, cardiological problems, misregulation of antiplatelet/antithrombotic drugs and infections from other systems (gastrointestinal, urinary, etc.). Elderly male patients planned for major/oncologic surgery were most possible to have their operation postponed for medical reasons. DISCUSSION-CONCLUSIONS: Thoracic operations are postponed owed to organisatory as well as medical reasons, the latter mainly affecting elderly, morbid patients awaiting for major/oncologic surgery.

To investigate the controlling efficacy of ondasetron and haloperidol in regard to the postcardiotomy delirium.

Accessory fissures represent a variation of the normal lung anatomy. Incomplete development or even the absence of the major or minor fissures can lead to confusion in distinguishing adjacent lobes. This report aims to present a rare intraoperative finding of an anatomic malformation of the right lung in a 19-year old male patient with recurrent pneumothorax who underwent a surgical repair. An accessory fissure which was separating the superior segment of the lower lobe from the basal segments gave to the whole lung the unique image of a four-lobed one. A profound knowledge of the accessory fissures, even if they are incidentally discovered, is of pivotal importance for the thoracic surgeon and leads to optimal operative assessment and strategic planning.

To investigate the reasons that lead to postponement of cardiac operations, in order to elucidate the problem and help patients through modes of prevention. METHODS-DESIGN: We retrospectively included in the study all patients submitted to elective adult heart surgery in our department during the 4-year period 2007-2010 and noted all cases of postponement after official inclusion in the operating schedule. 94 out of a total of 575 patients (16.34%) scheduled for elective cardiac operation had their procedure postponed. The reasons were mainly organisatory (in 49 cases, 52.12%), which in order of significance were: unavailability in operating rooms, shortage in matching erythrocyte units and shortage in anaesthetic/nursing staff. The rest of the cases (45, 47.88%) were postponed due to medical reasons, which in order of significance were: febrile situations, including infections of the respiratory, gastrointestinal and urinary system, problems with the regulation of antiplatelet and antithrombotic drugs, neurological manifestations such as stroke and transient ischaemic attacks, exacerbation of asthma/chronic obstructive pulmonary disease, arrhythmias, renal problems and allergic reactions to drugs. Patients with advanced age and increased Euroscore values were most possible to have their heart operation postponed. Heart operations are postponed due to organisatory as well as medical reasons, the latter mainly affecting older, morbid patients who therefore require advanced preoperative care.

Background: Anatomic deviations, especially those detected during the course of an operation, are medically intriguing, as they raise concerns about their clinical significance and putative complications. Case presentation: We present, to our knowledge, for the first time a case of an anatomic deviation in the form of a second right atrial auricle in a 70 year-old, coronary bypass-operated male Caucasian patient of Greek origin. No complications were noted intra-or postoperatively. Conclusions: A second right atrial auricle was found intraoperatively, without causing any clinical complications, or obstructing the normal course of a surgical procedure.

Aim. To investigate the possible connection of Poland's syndrome with the presence of lung bullae and, thus, with an increased risk for recurrent pneumothorax. Patients-methods. Two male patients, aged 19 and 21 years respectively were submitted to our department after their second incident of pneumothorax. Both had Poland's syndrome (unilaterally hypoplastic chest wall with pectoralis major muscle atrophy) and both had multiple bullae to the ipsilateral lung based on CT findings. The patients were treated operatively (bullectomy, lung apicectomy, partial parietal pleurectomy and chemical pleurodesis) due to the recurrent state of their pneumothorax. Results. The patients had good results with total expansion of the affected lung. Conclusions. Poland's syndrome can be combined with ipsilateral presence of lung bullae, a common cause of pneumothorax. Whether this finding is part or a variation of the syndrome needs to be confirmed by a larger number of similar cases.

The aortic Dacron wrapping technique is a surgical technique used under certain circumstances in cases of ascending aorta dilatation. Herein, we are presenting our experience on the method performed on multimorbid patients who denied major aortic surgery.

Achondroplasia is a musculoskeletal disorder associated with short stature. Despite an estimated prevalence of 1:25,000 in the general population, there is little literature concerning the diagnostic and treatment challenges faced by doctors dealing with a heart operation on a patient with this condition.

The aim of the present study was to evaluate the efficacy of autologous blood pleurodesis in the management of persistent air leak in spontaneous pneumothorax. A number of 15 patients (10 male and 5 female) were included in this prospective study between March 2005 and December 2009. The duration of the air leak exceeded 7 days in all patients. The application of blood pleurodesis was used as the last preoperative conservative method of treatment in 12 patients. One patient refused surgery and two were ineligible for operation due to their comorbidities. A blood sample of 50 ml was obtained from the patient's femoral vein and immediately introduced into the chest tube. A success rate of 27% was observed having the air leak sealed in 4 patients in less than 24 hours. Despite our disappointingly poor outcome, the authors believe that the procedure's safety, convenience and low cost establish it as a worth trying method of conservative treatment for patients with the aforementioned pathology for whom no other alternative than surgery would be a choice.
