A coronal MRA MIP image showed a lateral marginal vein arising off the left common iliac vein
and extending laterally to the left lower extremity (Figure 3).
We report a 27-year-old man with a history of atrial fibrillation, pericarditis, and May-Thurner syndrome who underwent a venoplasty with two self-expandable stents in the left common iliac vein
The degree of venous compression was calculated as the diameter of the common iliac vein
at the site of maximal compression divided by the mean diameter of the uncompressed proximal and caudal left common iliac vein
6] However, an important consideration is the physical length of the catheter and its position relative to the common iliac vein
Bullet entry tear was found in the inferior vena cava however, the bullet was found lodged in the right common iliac vein
and slipped down against the flow of blood.
Such a large pendulous growth on right side of sacralised lumbar vertebra can cause compression of related neurovascular structures like right common iliac vein
, inferior vena cava, right common iliac artery, right sympathetic chain, right lumbosacral trunk, ureter and rectum leading to respective pressure symptoms like oedema or necrosis of lower limb, constipation, bladder and bowel dysfunction, etc.
These can also rupture into adjacent viscera like rectum, bladder, and common iliac vein
Contrast abdominopelvic CT showed an old complete thrombosis of the left common iliac vein
, recent complete thromboses of the left venous junctions (external and internal iliac veins, common femoral deep and superficial veins, ascending lumbar vein and various presacral collaterals), dilated azygos vein, partial eccentric thrombosis of the IVC, approximately 18 mm lower than the flow level of the right renal vein, with a 5mm clot on a length of 27mm, with a reduced caliber on almost its entire length from the origin to the level of the caudate lobe.
Transseptal catheterization was performed from the left groin to align the tracking of balloon and septal puncture needle with IVC and common iliac vein
and facilitate LV entry.
In 45 cases involved in vascular injuries, the Left common iliac vein
injured in 32 cases, right common iliac vein
in 3 cases, left internal iliac artery in 3 cases, left common iliac artery in 4 cases, left internal iliac vein in 2 cases and inferior vena cava in one case.
An entry angle of 45[degrees] to 60[degrees] will carry the needle or trocar toward the bladder or uterus and away from the aorta and left common iliac vein
Left external & internal iliac veins drains into the retroperitoneal collaterals due to absence of left common iliac vein
