Protection of the spinal cord from ischemia: comparative effects of levosimendan and iloprost.

BACKGROUND: The purpose of the study was to investigate and compare iloprost and levosimendan on spinal cord ischemia in an experimental model. MATERIALS AND METHODS: The study was done in two stages. For the 4-hour short survival study, 50 New Zealand white rabbits were randomly allocated into five groups. Spinal cord ischemia was induced by clamping the aorta just below the left renal artery and just proximal to the aortic bifurcation with bulldog artery clamps. The aortic clamps were removed after 40 min and restoration of blood flow was verified visually. The groups were analyzed at 1 and 4 h after reperfusion. For the 48-hour survival study, two different groups (iloprost plus levosimendan, n = 10; saline-treated controls, n = 10) were analyzed at 24 and 48 h after reperfusion. RESULTS: The neurologic status of the animals in the treatment and sham groups was better than that in the control group both at 1 and 4 h after reperfusion. Viability index values in the levosimendan, iloprost and iloprost plus levosimendan groups were statistically higher than in the control group indicating less or no neuronal damage. DISCUSSION: The results suggest that levosimendan, as well as iloprost, may reduce ischemic damage in transient spinal ischemia and provide better neurologic outcome.

Injuries of the peripheral arteries and their surgical treatment.

196 cases of peripheral arterial injury presented to our clinic between 1976 and 1986 are summarised. Most of the cases were between 11 and 30 years of age and most of the injuries were by fire-arms and sharp weapons. The most common localisations were a. femoralis (29% cases), a. poplitea and branches (28%), a. brachialis injury (20%). The most common surgical measures were end-to-end anastomosis (43% cases) and venous orthograft replacement (17%). There were 5 mortalities. Factors affecting treatment success are discussed.

The hydatid cyst of the lung in children and results of surgical treatment.

Between 1976 and 1986 one hundred and ten children with pulmonary hydatid disease were treated surgically. Sixty five of the patients were males and 45 were females. We diagnosed hydatid cyst in 36 cases submitted in our clinic with hemoptysis. Thirty of the patients had cough, 16 had chest pain and dyspnea, 12 had purulent sputum and 8 cases had fever and anaphylactic phenomena. In most of the patients hydatid cysts were localised in the right lung. However, they had affinity for the lower lobes of both lungs, rather than the upper lobes. The radiological examination was found to be the most reliable diagnostic method. In the majority of our cases we performed thoracotomy + cystotomy + capitonnage, while in some cases we performed resection, like cystectomy, wedge resection and lobectomy. We did not encounter any serious operative and postoperative complications, except for one pleural empyema and a single case of mortality.

[Closed injury of the pericardium]. / Fedett pericardium sérülés.

The closed rupture of the pericardium without accompanying intrathoracal injuries, is a rare lesion. These cases are diagnosed generally at autopsy. Authors describe a case, successfully treated by operation.

Surgery in hydatid cyst of the lung. A report of 460 cases.

A series of 460 surgically treated cases of hydatid cyst of the lung is presented. Radiologic preoperative diagnosis was made in 90% of the patients. Cystotomy with subsequent capitonnage was performed in 395 cases, wedge resection in 27, lobectomy in 15 and segmental resection in 23 cases. After careful hemostasis, two drains were placed in the thorax and the thoracic cavity was closed. There were three postoperative deaths (0.6%) and two recurrences of cyst (0.4%) during follow-up investigation for periods up to 10 years.
