“…It should be noted that measurement of tilting in our study was done using a tube with 26 mm × 21 mm dimensions, which corresponds to the maximum dimensions measured during normal respiratory cycles and Valsalva maneuvers [11]. The influence of the caval diameters less than 21 mm or greater than 26 mm on the measurement of tilting is unknown.…”

“…This is especially true with regard to IVC, and this phenomenon is minor in iliac veins as long as the venous pressure is adequate. 9,10 That is why to establish its real diameter to guide angioplasty balloon and stent selection, a CLD derived from CSA was calculated in this study. Based on the present studies, the following reference diameters should be considered: 18 mm for IVC, 16 mm for LCIV in men and 15 mm in women, 15 mm for RCIV in men and 14 mm for RCIV in women and 14 mm for EIVs in men and 13 mm in women.…”

Objectives The purpose of this study is to report the intravascular ultrasound morphometry of iliac veins and its relation to demographic and anthropometric factors in subjects without chronic venous insufficiency. Methods Thirty-three patients, without chronic venous insufficiency – qualified to great saphenous vein stripping due to unilateral, primary varicose veins – participated in the study. During the surgery, left and right external iliac veins, common iliac veins and inferior vena cava were interrogated with intravascular ultrasound. The morphometric analysis included measurement of a cross-sectional area at normal, non-stenosed vein segments (ref-CSA) and at the point of the most prominent narrowing (minimal lumen area (MLA)). Based on these measurements, a percentage of stenosis (S%) and calculated lumen diameter of interrogated veins were determined according to the following formulas, S% = (ref-CSA–MLA)/ref-CSA × 100 and CLD = 2 × √(ref-CSA/π), respectively. Results Median ref-CSA, S% and calculated lumen diameter were 265.3 mm2, 45.8% and 18.4 mm for inferior vena cava; 193.9 mm2, 62.4% and 15.7 mm for left common iliac veins; 166.9 mm2, 35.7% and 14.2 mm for right common iliac veins; 136.5 mm2, 48.0% and 12.8 mm for left external iliac veins and 140.9 mm2, 46.3% and 13.5 mm for right external iliac veins. There were statistically significant differences between left and right common iliac veins ref-CSA, common iliac veins S% and common iliac veins calculated lumen diameter (p = 0.03, p < 0 and p = 0.03, respectively). The S% of left external iliac veins was greater in women 52.2 versus 37.2% in men (p = 0.04). Neither age nor anthropometric factors had any influence on the calculated lumen diameter of the analysed veins. A negative correlation between the left common iliac veins S% and the age was observed (p = 0.03). Conclusions In adult subjects, the calculated lumen diameter of the common iliac veins is greater on the left side and is not influenced by age and body size. Common iliac vein stenosis occurs more frequently on the left side, decreases with age and tends to be more frequent in women.

“…Also, caliber changes are larger in veins than arteries. Murphy et al (7) reported that the inferior vena cava deforms during the normal respiratory cycle. Its diameter significantly increased with the Valsalva maneuver from 14.3 ± 4.1 to 19.6 ± 1.2 mm in the short axis and the vessel became approximately 40% larger during this maneuver.…”

Transcatheter venous embolization with metallic coils is a safe and reliable method for the treatment of pelvic congestion syndrome and pelvic varicocele. While rare, coil migration to the pulmonary arteries is potentially fatal. We report the migration to the pulmonary artery of a cluster of nine metallic microcoils placed in the internal iliac vein to obliterate giant rectal varices. Our patient suffered no severe sequelae. To avoid coil migration to the pulmonary arteries, the coils chosen for placement must take into consideration the characteristics of the target vessels, particularly of larger veins.
