Technical Details of Surgical Treatment of a Severely Displaced Sternal Fracture.

Sternal fracture is an uncommon injury, which is managed conservatively in most patients. In case of failure of non-surgical management or severely displaced fractures, open reduction and internal fixation should be considered. In this case report, we present the technical details of open reduction and internal fixation for a severely displaced sternal fracture in a bicyclist. The sternal fracture was successfully treated, and the patient benefited from the rapid control of symptoms, early mobilization, and good cosmetic outcome. CONCLUSION: Open surgical treatment of a sternal fracture, when indicated, can be performed safely, with rapid control of symptoms, low risk of non-union, and good cosmetic outcome.

First Experience with Extracorporeal Membrane Oxygenation in Iran, under Difficult Conditions.

Background: Extracorporeal membrane oxygenation (ECMO) provides hemodynamic and oxygenation support in critical conditions. The commencement of this modality in Iran coincided with severe economic constraints across Iran. Methods: This retrospective study was performed in Masih Daneshvari Medical Center from 2010 to 2015, during which period, sanction-related limitations in the import of equipment prompted us to integrate a Medtronic or Stöckert head pump console into a Maquet ECMO Oxygenator so as to sustain the ECMO program. Comparisons were performed between successful and unsuccessful ECMO procedures and survivors. Factors associated with unsuccessful ECMO were evaluated with a multivariate logistic regression. Results: Thirty-three (68.8%) patients were male and 15 (31.2%) were female. The mean age of the patients was 35±16.6 years. Thirty-seven (77.1%) patients were weaned off ECMO successfully; the rate was higher than that in previous studies. Totally, 35.4% of the study population survived to hospital discharge. The most common cause of death in all the ECMO patients who were successfully weaned was sepsis. The most common cause of death in the patients who underwent unsuccessful ECMO was multisystem organ failure. The mean ECMO support time was 53.37±46.26 hours. The patients who were alive at discharge were significantly younger (25.5±14.5 vs. 40.2±15.5 y; P=0.002) and had a significantly lower ECMO duration (24 [25-75% interquartile: 18.5-36] vs. 48 [25-75% interquartile: 24-72] h; P=0.044) than the non-survivors. Conclusion: An assembly of ECMO components from different companies could be done safely, at least for a short period of time.

Obstructive Tracheal Pseudomembrane.

Obstructive tracheal pseudomembrane is a rare complication of endotracheal intubation, which could cause fatal airway obstruction following extubation. Hereby, we reported a patient who had only undergone a short course of intubation for a laparoscopic cholecystectomy and developed progressive respiratory distress after extubation.

Superior vena cava obstruction after heart transplantation.

Superior vena cava obstruction can be a serious complication after heart transplantation. A 58-year-old man with ischemic cardiomyopathy underwent orthotopic bicaval heart transplantation. On the 12th postoperative day, one hour after removing the central venous line, he developed sudden onset of facial edema, cyanosis, and tachycardia. Emergency transesophageal echocardiography revealed superior vena caval thrombosis at the site of anastomosis. Considering the risks of surgical reexploration, the superior vena cava was recanalized by stent deployment. All of the patient's symptoms were relieved a few hours after stent placement.

Ten years' experience in surgical treatment of right middle lobe syndrome.

PURPOSE: In this study we present the clinical, radiological, pathological, bronchoscopic and surgical results of 40 patients with diagnosis of middle lobe syndrome who were referred to our thoracic surgery unit for surgical intervention in a 10 years period. METHODS: Forty patients with obstructive and non-obstructive causes of middle lobe syndrome referred to our thoracic surgery unit. Clinical data were collected from the patients' records in a ten years period. This study evaluates diagnostic approaches and surgical treatments in right middle lobe syndrome. RESULTS: We studied 23 females (57.5%) and 17 males (42.5%) with a mean age of 31.7. Clinical findings were cough 95%, sputum 80% and intermittent hemoptysis in 50% of patients. Middle lobe collapse was seen in CT scan of all patients. Bronchiectasis was the most common pathologic finding (55%). Tuberculosis was not rare and was final pathology in 20% of patients. In three patients ruptured hydatid cyst was final finding. Surgery was done without mortality and with only minor complications. CONCLUSION: Lobectomy of right middle lobe is a good therapeutic option in these patients. Due to high prevalence of tuberculosis and hydatid cyst in Middle Eastern countries these two must be considered as causes of middle lobe syndrome.
