Abstract

We have previously categorised of degeneration of the collecting lymphatic vessels into four types: normal, ectasis, contraction and sclerosis type (NECST classification). Herein, we evaluated the collecting lymphatic vessels in lymphoedema-affected limbs using ultrasonography. In step 1, we investigated 110 lymphatic vessels from 25 patients with lymphoedema, who underwent lymphatic-venous anastomosis (LVA) following preoperative ultrasonography. We classified the lymphatic vessels using the NECST classification during intraoperative microscopic observation. Post-operatively, we evaluated the preoperative ultrasonographic images and identified the lymphatic vessels. In step 2, we investigated 79 lymphatic vessels from 17 patients. We performed ultrasonography and detected the lymphatic vessels preoperatively and compared the results with the intraoperative findings. This study is not blinded. In step 1, normal-type lymphatic vessels were observed as spicular and flat hypo-echoic lesions on ultrasonography. Ectasis-type lymphatic vessels appeared as a rounded hypo-echoic region and coloured on Doppler imaging once in 20-30 s. Contraction-type lymphatic vessels appeared as a small hypo-echoic region in the centre of the hyper-ec...Continue Reading

Attention Disorders

Attention is involved in all cognitive activities, and attention disorders are reported in patients with various neurological diseases. Here are the latest discoveries pertaining to attention disorders.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
