Discrepancies in the assessment of thoracoabdominal asynchrony are observed depending on the choice of respiratory movement sensors. We test the hypothesis that these discrepancies are due to a different dependence of the sensors on cross-sectional perimeter and area variations of the chest wall. First, we study the phase shift between perimeter and area (Phi(PA)) for an elliptical model, which...

BACKGROUND Morbidity and mortality after conventional repair of thoracoabdominal aneurysms remain high. Alternative techniques have been proposed and are the subject of this report. METHODS AND RESULTS Endovascular grafts that have a means of incorporating the visceral vessels into the aortic repair were divided into devices with fenestrations and those with formal branches. Hybrid procedures...

Intravital microscopy has been recognized for its ability to make physiological measurements at cellular and subcellular levels while maintaining the complex natural microenvironment. Two-photon microscopy (TPM), using longer wavelengths than single-photon excitation, has extended intravital imaging deeper into tissues, with minimal phototoxicity. However, due to a relatively slow acquisition r...

BACKGROUND Managing hemodynamically stable patients with thoracoabdominal stab wounds is still under dispute. This study aimed at discussing cut-off points of red blood cell (RBC) count in diagnostic peritoneal lavage (DPL) effluent in these patients. METHODS Three hundred and eighty-eight patients with thoracoabdominal stab wounds and hemodynamically stable status were enrolled. In cases wit...

Thoracoabdominal aortic aneurysms (TAAAS) are perrnanent localized dilations of the aorta that involve the celiac axis and extend proximally or distally from this point. Open surgical repair of TAAAS has traditionally involved greater operative risk than repairs of aneurysms in other aortic segments. However, experienced surgical centers now have much lower mortality and morbidity rates for TAA...
