The aim of this study was to describe the features of myocardial lymph flow using a new combined method of visualization of the lymphatic system. The study was performed on pig hearts harvested from a local slaughterhouse. The original dye, consisting of lipid-soluble chlorophyll and lipiodol, was injected stepwise into the lymphatic vessels. After sufficient optical identification of the lymphatic vessels, continuous injection of air into the coronary arteries was performed and CT scans were done. In this way, both optical and radiologic visibility of the cardiac lymphatic system was achieved. It was shown that lymph flow of the left and most part of the right ventricle is carried out through lymphatic collectors of the anterior wall of the heart, including retrogradely with respect to the right coronary artery, which complements the previously known facts about the structure of the lymphatic system of the heart.

Aim: Vascularized lymph node transfer (VLNT) accelerates growth factor secretion, lymphatic endothelial cell migration toward the interstitial flow and lymphagiogenesis in a multidirectional pattern. Our observational study aimed to examine the hypothesis that nanofibrillar collagen scaffolds (NCS) combined with VLNT can provide guided lymphagiogenesis creating long-lasting lymphatic pathways.
Methods: Twenty-four patients (21 female, 3 male) underwent a lymphatic microsurgery for upper ( = 11) or lower ( = 13) limb secondary lymphedema and completed at least 18 months follow-up were selected and equally divided in 2 groups; Group-A underwent VLNT, Group-B underwent combined VLNT and NCS procedure.

Purpose: Investigating the diagnosis and treatment of bilateral Chylothorax after neck lymph node dissection for thyroid cancer.
Methods: The clinical data of a patient with bilateral chylothorax after neck lymph node dissection for thyroid cancer were retrospectively analyzed, and the relevant literature was reviewed.
Results: The patient underwent a total thyroidectomy and left neck lymph node dissection, with no evidence of lymph fluid leakage observed during the operation.

Introduction: Microscopic assessment is essential in the study of mediastinal lymph nodes. Obtaining cytological samples through Endobronchial Ultrasound TransBronchial Needle Aspiration (EBUS-TBNA) has long been considered the gold standard procedure. The implementation of the World Health Organization (WHO) Reporting System for Lymph Node Cytopathology, along with the advancement of the CryoEBUS lymph node technique, has enhanced and refined diagnostic accuracy in this field.
