Permeability of lymphatic vessels

American Journal of Physiology-Legacy Content, 1962
Substances of various molecular sizes were infused through leg or mesenteric lymphatics of anesthetized dogs and their concentrations were followed in thoracic duct lymph and plasma for the subsequent 2 1/2 hr. An isolated in vivo popliteal lymph node preparation was also perfused with some of the same substances. Small molecules were found to diffuse

Biomechanics of a Lymphatic Vessel

Journal of Vascular Research, 1975
The principles of mechanics and the current notions of lymphatic physiology are integrated into a simple mathematical model of a lymphatic vessel which establishes a theoretical base for lymph propulsion in the lymphatic system. The model specifically considers the active and passive contractilities of the lymphatics.

Optimal Sites for Supermicrosurgical Lymphaticovenular Anastomosis: An Analysis of Lymphatic Vessel Detection Rates on 840 Surgical Fields in Lower Extremity Lymphedema Patients

Plastic and Reconstructive Surgery, 2018
Background: Supermicrosurgical lymphaticovenular anastomosis is becoming a useful treatment option for progressive lower extremity lymphedema because of its minimal invasiveness.

Lymphatic vessel diameter in female pelvic cancer‐related lower extremity lymphedematous limbs

Journal of Surgical Oncology, 2018
Lymphaticovenular anastomosis (LVA) has become one of the useful surgical treatments for compression‐refractory lower extremity lymphedema (LEL). It is important to anastomose larger lymphatic vessels with abundant lymph flows in LVA surgery.

Optimal Lymphatic Vessel Structure [PDF]

The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
Lymphatic vessels transport excess interstitial fluid from the low-pressure tissues to the higher pressure veins. The basic structural unit of lymphatic vessels is the lymphangion, a segment of the vessel separated by two unidirectional valves. Lymphangions cyclically contract like ventricles and can actively pump lymph.

Efferent Lymphatic Vessel Anastomosis: Supermicrosurgical Efferent Lymphatic Vessel-to-Venous Anastomosis for the Prophylactic Treatment of Subclinical Lymphedema

Annals of Plastic Surgery, 2016
BackgroundIn lower extremity lymphedema secondary to pelvic cancer treatments, lymphedema develops despite that the inguinal lymph nodes (LNs) are preserved.

Biological functions of lymphatic vessels

Science, 2020
Roles of organ-specific lymphatic vessels Lymphatic vessels are spread throughout the human body and have critical functions in mammalian physiology. Petrova et al. review emerging roles of the lymphatic vasculature in organ function and pathology and provide perspectives beyond the traditional view of ...

Lymphatics and blood vessels

Clinics in Dermatology, 2011
The traditional nomenclature of vascular lesions has been enlarged and modified with the usage of newer diagnostic techniques. Digital technology has enhanced the precision of older analog tools such as Doppler flow studies. Angiograms have also more precisely delineated flow patterns to allow planned surgical intervention as an important therapeutic ...

Blood Vessels and Lymphatic Vessels

2019
Development of the vascular and lymphatic trees is essential for the formation of nearly every organ during embryonic and fetal life. In the fetus, there are some unique features of the vascular tree that facilitate the fetoplacental circulation in utero, such as the umbilical vein, umbilical arteries, ductus venosus, and ductus arteriosus.
