Lymphovenous anastomosis: sphincter insufficiency and its consequences

Abstract

The aim of the study was to study the lymphovenous anastomosis in sphincter insufficiency.
Material and methods. Evisceration of the terminal portion of the thoracic lymphatic duct from 15 cadavers was performed. The inclusion criteria were edema and ascites, which were observed in patients who died from various diseases. The medical history was obtained after the autopsy. The isolation of the terminal part of the thoracic lymphatic duct was carried out according to a modified author's patented technique. Adipose tissue from the obtained biomaterial was cavitated with an ultrasound machine for better visualization of the vascular architecture and for identification of the lymphovenous junction with the sphincter apparatus zone.
Results. The study showed detected rare cases of thrombi in the lymphovenous anastomy, formed in the lumen of the lymphatic vessel, which leads to its obstruction and, as a result, imbalance of the lymphovenous anastomy. The article presents unique macro photos of the thrombus.
