11. Pulmonary embolism : validation of diagnostic imaging methods in the clinical setting
Sammanfattning : Pulmonary embolism (PE) is an elusive diagnosis and none of the existing imaging modalities have a 100% diagnostic specificity or sensitivity. Pulmonary arteriography (PA) is the most specific test although the improvement of computed tomography technique has made this a commonly used method. Lung scintigraphy often gives ambiguous results.

12. Technical Aspects of Laparoscopic Liver Resection. An Experimental Study
Sammanfattning : Various techniques are used to transect the liver. With increase in laparoscopic liver resections (LLR), it is of even more interest to develop surgical techniques to minimize bleeding and the risk for gas embolism during transection. Instrument like argon enhanced coagulator provides good hemostasis but increases the danger of gas embolism. LÄS MER
