Abstract
This study was undertaken to determine the prevalence of vascular compression in manometric tracings and to determine whether these findings had any clinical significance. Vascular compression, defined as a localized area of elevated intraesophageal resting pressure >4 mm Hg with superimposed cyclic pressure spikes with a frequency of 60–100/min, was noted in 55 of 241 consecutive tracings. The groups with and without vascular compression were similar with regard to mean age, sex, and prevalence of dysphagia. Radiographs were available for 29 of the 55 and showed compression in 18, but there was no relationship with the manometric findings, except for a trend towards finding a positive esophagogram with amplitudes >16 mm Hg. Eleven tracings showed absent “relaxation” of this elevation of pressure in response to swallows, and five of six available esophagograms showed a corresponding area of compression. We conclude that manometric evidence of vascular compression is common and generally has no clear relationship with esophagographic findings or dysphagia. However, the combined findings of marked increases in pressure and absence of relaxation in response to swallows may indicate evidence for a vascular cause of dysphagia.
