Abstract: A method of determination of a cause of hemorrhoids in a subject includes a determination of the presence of hemorrhoids in the subject by visual inspection, and by one or more of a non-invasive medical imaging procedure and/or an intra-vascular visualization procedure, determining if there is an obstruction or occlusion in an iliac vein of the subject, and if so, determining that the hemorrhoids were caused by such obstruction or occlusion. If the obstruction or occlusion are determined to be the cause of the hemorrhoids, a procedure for compressing the obstruction or occlusion in the iliac vein of the subject, such as by angioplasty or stenting, is performed. After an appropriate time period, changes to the hemorrhoids in the subject are determined by a subsequent visual inspection.
