transverse Pericardial Sinus closure in acute type a aortic dissection operation
The Annals of Thoracic Surgery, 2017Co-Authors: Liangwan Chen, Xiaofu DaiAbstract:In operations for acute type A aortic dissection with open technique in elderly patients and patients with long-term treatment of anticoagulation, the transverse Pericardial Sinus was routinely closed before the graft implantation. With the aid of both a bovine Pericardial patch covering the Pericardial recess between the superior caval vein and the pulmonary artery and an opening in the left inner side of the superior caval vein, this prophylactic transverse Pericardial Sinus closure could make autotransfusion of blood loss into the central venous system possible to deal with the diffuse oozing from the suture line.

Interaction of the tracheal tubules of Scutigera coleoptrata (Chilopoda, Notostigmophora) with glandular structures of the Pericardial septum
Pensoft Publishers, 2015Co-Authors: Gero Hilken, Gregory D. Edgecombe, Carsten H.g. Mueller, Andy Sombke, Christian S. Wirkner, Jörg RosenbergAbstract:Notostigmophora (Scutigeromorpha) exhibit a special tracheal system compared to other Chilopoda. The unpaired spiracles are localized medially on the long tergites and open into a wide atrium from which hundreds of tracheal tubules originate and extend into the Pericardial Sinus. Previous investigators reported that the tracheal tubules float freely in the hemolymph. However, here we show for the first time that the tracheal tubules are anchored to a part of the Pericardial septum. Another novel finding is this part of the Pericardial septum is structured as an aggregated gland on the basis of its specialized epithelium being formed by hundreds of oligocellular glands. It remains unclear whether the Pericardial septum has a differently structure in areas that lack a connection with tracheal tubules. The tracheal tubules come into direct contact with the canal cells of the glands that presumably secrete mucous substances covering the entire luminal cuticle of the tracheal tubules. Connections between tracheae and glands have not been observed in any other arthropods

computerized tomography of the transverse Pericardial Sinus normal or pathologic
Clinical Anatomy, 2017Co-Authors: Anna żurada, Andrzej Ustymowicz, Marios Loukas, Maciej Michalak, Dorota Czyzewska, Jerzy GieleckiAbstract:The transverse Pericardial Sinus is a uniquely located structure subdivided into many parts. However, discrepancies still exist on the nomenclature and divisions. As noninvasive diagnostic technology such as CT and MR imaging improve, the transverse Pericardial Sinus and constituent recesses are visualized with more clarity, increasing the risk for misinterpretation. In this review, we will explore the anatomy of the transverse Pericardial Sinus and associated recesses with the goal of heightening awareness regarding the differential diagnosis between normal and pathological states as seen on CT. In addition, the inconsistencies of the right lateral superior aortic recess are also addressed. Last, we describe the clinical and surgical significance of the transverse Pericardial Sinus. Clin.
