Lymphatic obstruction is a blockage of the lymph vessels that drain fluid from tissues throughout the body and allow immune cells to travel where they are needed. Lymphatic obstruction may cause lymphedema, which means swelling due to a blockage of the lymph passages

Dilation of a lymph vessel refers to the abnormal enlargement or widening of a lymphatic vessel, which can occur due to various factors such as increased fluid pressure, obstruction, or inflammation. This condition can lead to impaired lymphatic drainage and may result in swelling (lymphedema) in the affected area. Dilation can also be associated with certain medical conditions, including lymphatic malformations or infections. Proper diagnosis and treatment are essential to manage any underlying issues and restore normal lymphatic function.
If tissue lymphatics are blocked by a tumor or lymph nodes were excised to stop a tumor from metastasizing, the obstruction causes reduced lymphatic drainage, which leads to increased interstitial hydrostatic pressure, interstitial fluid volume, and eventually edema.
The parasitic roundworm that infects and swells the lymphatic system in the tropics is called Wuchereria bancrofti. It is responsible for lymphatic filariasis, a disease that causes severe swelling, particularly of the legs and genitals, due to the obstruction of lymphatic vessels. The worms are transmitted to humans through the bites of infected mosquitoes, and the disease can lead to significant morbidity and social stigma. Effective treatments and preventive measures are available, but the disease remains a public health challenge in many tropical regions.
Adipose tissue is fat, while lymphedema is a swelling of tissues due to obstructed lymphatic drainage from a part of the body.
Lymphoid swelling in appendicitis refers to the enlargement of lymphoid tissue in the appendix, often due to infection or inflammation. This swelling can lead to obstruction of the appendiceal lumen, contributing to the development of appendicitis. The increased lymphoid activity is typically a response to pathogens or irritants, and can play a role in the acute inflammatory process associated with the condition. In severe cases, this can result in complications such as perforation or abscess formation.
Filarial worms are responsible for several diseases, the most notable of which is lymphatic filariasis, commonly known as elephantiasis. This disease is characterized by severe swelling, particularly in the limbs and genitals, due to the obstruction of lymphatic vessels. Other diseases caused by filarial worms include onchocerciasis, also known as river blindness, and loiasis. These conditions can lead to significant morbidity and have a considerable impact on affected individuals' quality of life.
The central nervous system does not have a lymphatic system for drainage. This is due to the presence of the blood-brain barrier, which restricts the movement of substances between the blood and the brain tissue, including lymphatic fluid.
Post-operative bowel obstruction is a condition where the intestines become blocked following surgical procedures, preventing the normal passage of contents through the digestive tract. This obstruction can occur due to adhesions (scar tissue), hernias, or swelling resulting from the surgery. Symptoms may include abdominal pain, bloating, vomiting, and inability to pass gas or stool. Prompt diagnosis and treatment are essential to prevent complications, which may require additional surgery.
