Left pancreatectomy with conservation of the spleen but not of the splenic vessels, also known as the Warshaw technique (WT), is a rapidly developing procedure in pancreatic surgery. The left gastro-omental artery has been little studied and could play a key role in spleen viability during the WT. The objectives of this study were to perform an anatomical study of the topography of this artery, establish a simple anatomical classification of the left gastroomental artery, and to determine the feasibility of its conservation during WT.
We studied the topography of the left gastroomental artery and the feasibility of its preservation during the WT using data obtained by three methods: cadaveric dissection/analysis of splenic arteriograms/3D reconstructions of CT scans with contrast injection during the arterial phase in patients undergoing splenic embolization.
Dissection data showed that preservation of the left gastroomental artery during the WT is possible in 75% of anatomical configurations. Data for arteriography and CT scans with contrast injection showed that the left gastroomental artery played a major role in spleen vascularization in patients who had undergone embolization of the splenic artery.
It is often possible to preserve the left gastroomental artery during a WT, with potentially beneficial consequences for spleen vascularization.
