Abdominal aortic aneurysm rupture into a retro-aortic left renal vein
Abstract:
We present a case of an abdominal aortic aneurysm ruptured into a retroaortic left renal vein. The patient presented with left flank pain, left-sided varicocoele and haematuria. Imaging showed a juxtarenal AAA associated with a retroaortic left renal vein and simultaneous contrast captation of the aneurysm, the vena cava, the left renal vein and the left vena testicularis. After opening of the aneurysm sac, the defect was controlled by digital pressure and closed by suture. The patient underwent a successful abdominal aorto bi-iliac replacement. We discuss prevalence, clinical features and treatment options of this rare condition.

Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
