1) To investigate the relationship between operator experience and the success of outpatient hysteroscopy; and 2) to determine if the introduction of normal saline and the use of narrow-caliber hysteroscopes and vaginoscopic approach are associated with a lower failure rate.
Previous studies in older adults suggest that longer axial length is associated with narrower arteriolar caliber.
Villous vessels showed various degrees of abnormalities in the form of endothelial cell enlargement, folding, thickening and protrusion of their luminal surfaces into vascular lumen making it narrower in caliber.
Open image in new window Fig. 16 Eighty-two-year-old man with axial a, b and coronal c CT imaging demonstrating narrowed tracheal caliber and irregularity of the walls of the trachea, extending into the bilateral mainstem bronchus compatible with tracheobronchopathia osteochondroplastica. d Video still at the time of bronchoscopy demonstrating luminal narrowing of the trachea.
Previously published data have identified narrower venular caliber in association with AD [6], although this effect has not always been consistently observed [32].
Baseline characteristics (Table 1) demonstrated overall narrower arteriolar calibers in those with renal dysfunction.
To determine whether local nutritional or ischemic factors are involved in cataract pathogenesis, we aimed to assess whether narrowed retinal vessel caliber predicted the long-term incidence of age-related cataract, as shown in 1 previous report.
In the Wisconsin Epidemiology Study of Diabetes Retinopathy (WESDR), retinal arteriolar caliber narrowing was associated with lower extremity amputation, but neither arteriolar nor venular caliber was associated with self-reported DPN (9).
In recent years, American universities have been setting up outposts in nations where the opportunities for higher education are far narrower or of lesser caliber than in the United States, becoming, in effect, global universities.
Sheathing is distinguished from sclerosis as a yellowish appearance external to the vessel wall rather than narrowing of the vessel caliber.
Additional features that increase the likelihood of vascular encasement, including irregularity of the vessel contour, associated focal narrowing of the vessel caliber or tumor extension into the vessel lumen, should also be reported if present.
