“…IJV valves have been visualized in most patients examined and are located approximately 2–2·5 cm cephalad to the IJV–subclavian junction 5,14. Autopsy studies revealed the presence of IJV valves in 93–100% of subjects (Table 3).…”

Objective: To establish a detailed technical procedure for studying the anatomical correlates of chronic cerebrospinal venous insufficiency in cadavers of multiple sclerosis and control subjects, and to present our findings of the normal anatomic venous structures, with reference to previous descriptions from the literature.Methods: This study examined the internal jugular veins (IJVs), the brachiocephalic veins, and the azygos vein from 20 cadavers (10 control and 10 multiple sclerosis). These veins were exposed, isolated by clamps from the rest of the venous system, flushed with water, and then injected with fluid silicone from the superior ends of both IJVs. After the silicone cured to its solid state, the venous tree was removed en bloc and dissected longitudinally to expose the luminal surface. All vein segments were analyzed for anatomic variation. Anatomical analysis for this manuscript focused on normal vein architecture and its variants.Results: Thirty-seven of 40 IJVs contained valves: 29 bicuspid, 6 tricuspid, and 2 unicuspid. The average circumferences of the right and left IJVs were 2·2 and 1·8 cm, respectively. Thirteen of 20 azygos veins contained a valve, located on average 3·6 cm away from the superior vena cava junction. Nine of the 13 azygos valves were bicuspid; four were tricuspid. Only one of the 40 brachiocephalic veins contained a valve.Discussion: We detailed a technical approach for harvesting cadaveric neck and thoracic veins with relevance to chronic cerebrospinal venous insufficiency. The anatomy of the venous system has significant variability, including differing number of valves in different regions and variable characteristics of the valves. Average vein circumference was less than that typically reported in imaging studies of live patients.

“…In our observations of the FV, bicuspid valves predominated while monocuspid and tricuspid valves were occasional, which accords with Basmajian's findings (Basmajian, 1951). Most venous valves are bicuspid; mono-and tri-cuspid valves are rarer (Powell and Lynn, 1951;Staubesand and Rulffs, 1958;Dresser and McKinney, 1987;Harmon and Edwards, 1987;Miyake et al, 1996;Sanchez-Hanke et al, 2000;Celepci and Brenner, 2011). The presence and abundance of mono-and tri-cuspidity not only varies among venous systems, possibly depending on physical interactions with the surrounding tissues (Sanchez-Hanke et al, 2000), but also in the same venous system among populations.…”

The presence and abundance of mono-and tri-cuspidity not only varies among venous systems, possibly depending on physical interactions with the surrounding tissues (Sanchez-Hanke et al, 2000), but also in the same venous system among populations. Comparative fluidstructure interactions in virtual mono-, bi-and tricuspid venous valve models suggest that mechanical stress via shear force and wall pressures is lowest in bicuspid models (Chen et al, 2014).…”

Human Femoral Vein Diameter and Topography of Valves and Tributaries: A Post Mortem Analysis

The femoral vein (FV) is a clinically important vessel. Failure of its valves can lead to chronic venous insufficiency (CVI) with severe manifestations such as painful ulcers. Although they are crucial for identifying suitable implant sites for therapeutic valves, studies on the topography of FV tributaries and valves are rare. Moreover, the femoral vein diameter (FVD) must be known to assess the morphometric requirements for valve implants. To reassess the anatomical requirements for valve implants, 155 FVs from 82 human corpses were examined. FVDs and tributary and valve topographies were assessed using a laboratory straightedge. The FVD increased from 6 mm in the distal femoropopliteal vein to 11 mm in the iliofemoral vein proximal to the saphenofemoral junction (SFJ). Diameters were significantly bigger in males than females. Height correlated positively with FVD. Distal to the SFJ, within a distance of 38 cm, one to eight valves were present. Up to two valves were present within 10 cm proximal to the SFJ. Individual tributary and valve topography must be considered to ensure appropriate design and successful implantation of a venous valve for CVI therapy in the FV. A suitable implant site would be proximal to the SFJ via an infrainguinal transfemoral access. Clin. Anat. 31:1065–1076, 2018. © 2018 Wiley Periodicals, Inc.

“…A valve is present in the IJV at the junction with the subclavian vein. This valve may be bicuspid or tricuspid and is commonly located approximately 2 cm above the junction with the brachiocephalic vein (Sanchez-Hanke et al, 2000). A study of the IJV valve in cadaveric and live human subjects demonstrated the same valve location, mostly bicuspid, and also reported that only 7% of valves were incompetent out of 41 valves tested (Silva et al, 2002).…”

Endovascular Therapy for Chronic Cerebrospinal Venous Insufficiency in Multiple Sclerosis

Recent reports have emerged suggesting that multiple sclerosis (MS) may be due to abnormal venous outflow from the central nervous system, termed chronic cerebrospinal venous insufficiency (CCSVI). These reports have generated strong interest and controversy over the prospect of a treatable cause of this chronic debilitating disease. This review aims to describe the proposed association between CCSVI and MS, summarize the current data, and discuss the role of endovascular therapy and the need for rigorous randomized clinical trials to evaluate this association and treatment.

Abstract: The present study demonstrates the variety of the valves of the jugular vein. They play an important role to impede the retrograde flow during cardiopulmonary resuscitation as well as in jugular vein cannulation.
