睾丸腫瘍に対する後腹膜リンパ節郭清術後3年以上を経た症例のリンパ系造影

Abstract

Foot lymph angiography was performed in five patients who had passed more than three years after orchidectomy and retroperitoneal lymph node dissection for testicular tumor. This study gave the information as to the lymphatic flow and the regeneration of lymphatic tissue after such surgery. 1. Lymphangiograms showed the network structure of fine lymphatic channels emerging into the surrounding tissue from the end of dissection. There was no further visualization oflymph channels. These network lympbangiograms are probably the result of regeneration of the lymphatic capillaries. 2. There was no lymph node shadow in the dissected area. It was concluded that lymph node does not regenerate. 3. Lymphatic flow from the lower extremities is probably made through the routes such as dorsal lymphatics or paravertebral lymphatics after being absorbed from the lymphatic capillaries ofthe surrounding tissue of the dissection margin.
