Blockage

There is a blockage in this pipe, preventing water from entering it.

Several years ago, a rotavirus vaccine was taken off the market because it increased a baby's risk of developing a rare, but potentially deadly, intestinal blockage.

A few years ago, a group of experts examined studies of aspirin at the request of federal health officials in the United States. The experts said people with an increased risk of a heart attack should take a low-strength aspirin every day. Aspirin may help someone who is having a heart attack caused by a blockage in a blood vessel. Aspirin thins the blood, so the blood may be able to flow past the blockage. But experts say people should seek emergency help immediately. And they say an aspirin is no substitute for treatment, only a temporary help.

This disease is particularly harmful for young children. The adult worms can live up to 2 years, so intestinal blockage can become severe in tiny tummies.

Only when one has seen a Control Office at first-hand does one realise the vast amount of unsparing but largely unsung work that is behind the eventual publication, perhaps, of a paragraph in this journal's "Motive Power Miscellany" recording the appearance, within hours of the complete blockage of a main line, of many of its trains, passenger and freight, on routes quite foreign to them; and of effective emergency services either side of the disaster area.

There was a blockage in the sewer, so we called out the plumber.

Blockage of circulation quickly leads to ischemia.

In selected cases, endovascular thrombectomy can quickly remove a blockage that pharmaceutical thrombolysis can't budge.
