In cases in which complete obstruction of the remaining ureter occurs, patients will experience effects similar to obstruction of the entire lower urinary tract.
Hydrocephalus may be described as either communicating, in which the obstruction to the flow of CSF occurs outside the brain ventricles, or noncommunicating (also called obstructive hydrocephalus), in which the obstruction to the flow of CSF occurs within the ventricles.
MH, a reperfusion injury, is frequently observed and associated with large MIs during which microvascular obstruction also occurs [8].
Pulmonary arterial hypertension (PAH) is a disorder in which mechanical obstruction of the pulmonary vascular bed is largely responsible for the rise in mean pulmonary arterial pressure, resulting in a progressive functional decline despite current available therapeutic options.
One mechanism by which progressive obstruction can occur is through chronic inflammation.
We report two pediatric cases in which mechanical obstruction by volvulus mimicked an exacerbation of CIPS, requiring surgical intervention.
In this study, we describe a mouse model in which progressive obstruction of the IHBD results in a reduction of intact IHBD, without concomitant loss of ductal structures.
Fifty-five (55) patients had undergone emergency operations of which bowel obstruction had been the most common pathology (28 emergency patients, 51%); 45 had had elective surgery and among them 24 (53%) had received bariatric surgery.
Postbronchodilator spirometry was not performed in this study, so it is possible that some participants classified as having OBS may have had conditions more consistent with asthma (in which airflow obstruction is generally reversible) than with COPD.
Furthermore, it is important to point out that the model is not applicable to the environments and scenarios in which physical obstructions of the LoS occur.
