Abstract:
The effect of changes in bladder volume on the caliber of adjacent veins is underappreciated but essential to recognize to avoid complications such as unnecessary stenting or clot migration causing pulmonary embolism. Here the authors illustrate the importance of this finding in 3 cases using venographic and endovascular sonographic imaging: the first in which BPH-induced chronic bladder outlet obstruction resulted in DVT formation, the second in which the cause was unrecognized and unnecessary stenting performed, and the third in which inappropriate treatment was avoided by decompressing the bladder.
