With the rapid advancement of laparoscopic techniques, the minimally invasive benefits of laparoscopic splenectomy combined with pericardial devascularization have become increasingly evident. In this context, we present a protocol for performing laparoscopic splenectomy alongside pericardial devascularization to treat hypersplenism and esophageal variceal hemorrhage resulting from portal hypertension.

In this video, we discuss the correlation between the CIT50 and the multiplicity of viral infections. The virus-infected cells display cytopathic effects, causing their death and detachment from the gold microelectrode, which in turn, reduces the impedance.

(2020)This video demonstrates an impedance-based assay to measure glioblastoma cell invasion and migration. Cells degrade the extracellular matrix, move through microporous membranes, and adhere to electrodes, generating impedance. This real-time analysis reflects their invasive potential for cancer research applications.

FAQs
The sutures act as attachment points between the pericardium and a support structure. Once secured to a retractor or support frame, they elevate the pericardial sac and help maintain a selected position around the heart. This distributes the positioning function through the surrounding sac, allowing the operative field to remain supported while limiting dependence on direct cardiac handling.
Suspension provides a way to support and stabilize the operative field without depending solely on direct contact with the heart. By transferring positioning through the sutured pericardium and attached frame, the technique can help maintain exposure while reducing the need for continuous manual manipulation. This is particularly relevant when controlled access is important during open cardiac procedures.
Elevating the pericardial sac changes the relationship between the heart and the surrounding operative field. The resulting support can improve access to cardiac structures and help maintain a more consistent view during surgery. Because the arrangement combines elevation with stabilization, it provides a practical means of preserving exposure while the procedure requires controlled positioning.
Creation begins with placing sutures through the pericardium at positions that can support the operative exposure. The sutures are then secured to a retractor or another support frame, allowing the pericardial sac to be elevated. This sequence establishes the suspension system and creates a supported position for the heart during the open cardiac procedure.
The technique can improve visualization and facilitate access to cardiac structures by elevating and stabilizing the pericardial sac. Its value is greatest in procedures requiring controlled exposure of the heart, where maintaining a workable operative field is important. The cradle therefore functions as a positioning aid that supports access rather than serving as an independent surgical procedure.
Beyond operative support, the arrangement offers a practical framework for demonstrating cardiac anatomy, surgical positioning, and access to the heart. Learners can observe how sutures, the pericardium, and a retractor or support frame work together to shape exposure. This connects anatomical understanding with the spatial and procedural considerations encountered during open cardiac surgery.
