Key result
Physiological changes associated with left superior pulmonary vein resection are possible factors affecting left atrial hemodynamics after left upper lobectomy based on computational simulations.
Why the study?
Left upper lobectomy with left superior pulmonary vein resection alters left atrium physiological states and hemodynamics associated with thrombosis, but the underlying mechanism is poorly understood.
What are the effects of left superior pulmonary vein resection and associated physiological changes on left atrial hemodynamics after left upper lobectomy?
What are the effects of left superior pulmonary vein resection and associated physiological changes on left atrial hemodynamics after left upper lobectomy?
Physiological changes in the left atrium following left superior pulmonary vein resection during left upper lobectomy significantly alter hemodynamics, potentially contributing to thrombosis.

May increase post-lobectomy thrombosis risk; leaves open human validation of hemodynamic effects.
Left upper lobectomy (LUL) with left superior pulmonary vein (LSPV) resection alters the left atrium (LA) physiological states and LA hemodynamics associated with thrombosis, although this underlying mechanism is poorly understood. Therefore, we investigated the effects of LSPV resection and associated LA physiological changes on LA hemodynamics using four-dimensional computed tomography image-based computational simulations. Three cases were considered: the LA before and after LUL extracted from computed tomography images and artificial LSPV resection without physiological changes. Comparisons among the three cases demonstrated that physiological changes associated with LSPV resection are the possible factors that affect the LA hemodynamics after LUL.

Yi et al. (2023) studied Left upper lobectomy with left superior pulmonary vein resection. Left superior pulmonary vein (LSPV) resection and associated physiological changes vs. Left atrium before lobectomy and artificial LSPV resection without physiological changes was evaluated on Left atrial hemodynamics associated with thrombosis. Physiological changes associated with left superior pulmonary vein resection are possible factors affecting left atrial hemodynamics after left upper lobectomy based on computational simulations.
