Obstruction of the nasolacrimal duct, known as dacryostenosis, leads to the excess overflow of tears called epiphora.

Obstruction of pulmonary venules causes vascular congestion and hemoptysis, and lymphatic obstruction leads to chylothorax and chylous ascites.

Obstruction of pulmonary venules causes vascular congestion and hemoptysis, and lymphatic obstruction leads to chylothorax and chylous ascites.

Obstruction also causes centrilobular necrosis and peripheral lobule fatty change due to ischemia.

Obstruction involved giving lengthy speeches which were largely irrelevant to the topic at hand.

* Obstruction in the nasal passageway.

Obstruction charges can also be laid if a person alters or destroys physical evidence, even if he was under no compulsion at any time to produce such evidence.

Obstruction can include crimes committed by judges, prosecutors, attorneys general, and elected officials in general.

A project that included replacing its airfield lighting and signage with energy efficient LED lights where possible ( LEDs are only permissible for use on Taxiway Lights, Obstruction Lights, Signage and Medium Intensity Runway Lights at this time – the runway at San Diego uses High Intensity Runway Lights ) and is in the process of constructing 10 new gates for Terminal 2 West.

* Ureteral Pelvic Junction Obstruction ( UPJ ) is a rare condition beginning from birth in which the ureter is blocked between the kidney and bladder.

Obstruction by Irish members of parliament and a number of English MPs was causing a legislative backlog.

At 6. 53 Tinsley sent the " Obstruction Danger " bell signal to both Gretna and Kirkpatrick, stopping all traffic and alerting others to the disaster ..

Obstruction is not to be confused with interference.

Obstruction of the pancreatic duct because of either a benign or malignant process may result in chronic pancreatitis.

Obstruction may be the common underlying factor.

* Obstruction, e. g., of the intestines

* Malsberger, John W. From Obstruction to Moderation: The Transformation of Senate Conservatism, 1938-1952.

* Haemorrhagic necrosis is due to blockage of the venous drainage of an organ or tissue ( e. g., in testicular torsion ).

Other congenital cardiovascular malformations, such as partial anomalous venous drainage and aortic valve stenosis or aortic regurgitation, are also more common in Turner syndrome than in the general population.

Strangely, Turner syndrome seems to be associated with unusual forms of partial anomalous venous drainage.

The venous drainage of the duodenum follows the arteries.

The medullary sinuses converge at the hilum and lymph then leaves the lymph node via the efferent lymphatic vessel towards either a more central lymph node or ultimately for drainage into a central venous subclavian blood vessel, most via the postcapillary venules, and cross its wall by the process of diapedesis.

Through the mediastinum, the main lymphatic drainage from the abdominal organs goes via the thoracic duct ( ductus thoracicus ), which drains majority of the lymph from the abdomen to the above mentioned left venous angle.

published evidence that BPH is caused by failure in the spermatic venous drainage system resulting in increased hydrostatic pressure and local testosterone levels elevated more than 100 fold above serum levels.

The cavernous sinus lies within the cranial cavity, between layers of the meninges and is a major conduit of venous drainage from the brain.

Often it is necessary to use a tourniquet which restricts the venous drainage of the limb and makes the vein bulge.

* Orbital A. Ocular venous drainage block: central retinal venous block, cavernous sinus trombosis B. Local lesion: optic neuritis, ischemia of the nerve head, toxin ( methanol ), infiltration of the disc by glioma, sarcoidosis and lymphoma

Edema of the soft tissue within the compartment further raises the intra-compartment pressure, which compromises venous and lymphatic drainage of the injured area.

A mucocutaneous zone is often the site of an arterial anastomosis, a watershed area of venous and lymphatic drainage, and sensory ( but not motor ) nerve overlap.

The tonsils venous drainage is by the peritonsillar plexus, which drain into the lingual and pharyngeal veins, which in turn drain into the internal jugular vein.

In Veno-venous ECMO – venous cannulae are usually placed in the right common femoral vein for drainage and right internal jugular vein for infusion.

In contrast, the flow rate used during VA ECMO must be high enough to provide adequate perfusion pressure and venous oxyhemoglobin saturation ( measured on drainage blood ), but low enough to provide sufficient preload to maintain left ventricular output.

VA ECMO trials require temporary clamping of both the drainage and infusion lines, while allowing the ECMO circuit to circulate through a bridge between the arterial and venous limbs.

The drainage of the intestinal venous blood into the liver requires efficient detoxification of miscellaneous absorbed substances to maintain homeostasis and protect the body against ingested toxins.

ICP can also be lowered by raising the head of the bed, improving venous drainage.

These lesions are thought to represent developmental anomalies of normal venous drainage.

Arterial supply is by the Inferior mesenteric artery, and venous drainage is to the portal venous system.

The left supraclavicular node is the classical Virchow's node because it is on the left side of the neck where the lymphatic drainage of most of the body ( from the thoracic duct ) enters the venous circulation via the left subclavian vein. The metastasis blocks the thoracic duct leading to regurgitation into the surrounding nodes i. e. virchow's node.

The venous drainage of the cerebrum can be separated into two subdivisions: superficial and deep.
