Iliac vein compression syndrome: An underdiagnosed cause of lower extremity deep venous thrombosis,

JOURNAL OF HOSPITAL MEDICINE, Issue 7 2010
Ami Naik BS
Abstract Iliac vein compression syndrome (CS) is a rare cause of deep venous thrombosis. It is caused by an anatomic anomaly in which the right common iliac artery overlies the left common iliac vein causing mechanical compression. Subsequent endothelial changes within the vessels have the potential to spur thrombus formation. Aggressive diagnostic and therapeutic interventions must be implemented upon suspicion to avoid long-term complications. We report on a 19 year old male who presented with ICS. We discuss the clinical presentation, diagnosis, and current treatment options. Journal of Hospital Medicine 2010. © 2010 Society of Hospital Medicine. [source]

A new experimental inbred Wistar rat varicocele model: anatomy of the left spermatic vein and the effect on histology

ANDROLOGIA, Issue 1 2008
Y. Zhang
Summary Because of venous anatomical differences between rats and humans and the personal interpretation of these differences, there is neither consistent animal prototype nor consistent results in the study of varicocele. We established a new substrain of Wistar inbred rats, of which the left testis vein has no significant branches to the common iliac vein up pampiniform plexus, but instead enters the left renal vein directly (similar to humans) and used them to create experimental varicocele model by partial ligation of the left renal vein. One month later, the predominant lesion of the left testis in induced group was spermatogenic arrest at the spermatid and preliminary spermatocyte phases, and considerable interstitial and Sertoli cell vacuolation. The right testis also showed spermatogenic arrest. Most important, the characteristics of the lesions differed in both testes, with the left testis having more severe lesions. Allowing for the unique anatomy of the left spermatic vein, the standard of the surgical procedure, the high rate of varicocele induction, and identical histological alteration as occurs in humans, we believe that this inbred Wistar rat substrain is suitable for the creation of an experimental varicocele model, which has promise for practical application in humans.

Avulsion of ascending lumbar and iliolumbar veins in anterior spinal surgery: An anatomical study

CLINICAL ANATOMY, Issue 5 2007
G. Sivakumar
Abstract To expose the disc between the 4th and 5th lumbar vertebrae in anterior spinal surgery, left to right retraction of inferior vena cava and aorta is required. This manoeuvre can be complicated by venous haemorrhage that, in most cases, is due to avulsion of the left ascending lumbar vein (ALV) or the left iliolumbar vein (ILV). We dissected 23 embalmed cadavers to assess the factors that contribute to the risk of tearing these two veins during retraction. We describe a triangular region that should help surgeons in identifying the ALV and ILV. This triangle is defined by the lateral border of the common iliac vein, the medial border of the psoas major muscle, and the superior end-plate of the L5 vertebral body. We observed that 3 cm between the termination of the left ALV, or a common stem with the ILV, and the termination of the common iliac vein is the critical distance, less than which the risk of venous avulsion is highest. Although the sample considered is small, our study seems to suggest that male patients tend to have a higher risk of venous avulsion than female patients. Clin.

Successful management of bleeding with recombinant factor VIIa (NovoSeven®) in a patient with Burkitt lymphoma and thrombosis of the left femoral and left common iliac veins

PEDIATRIC BLOOD & CANCER, Issue 3 2007

Abstract We present the case of an 18-year-old female with Burkitt lymphoma involving the intra-abdominal and inguinal lymph nodes. The tumor had invaded the left femoral and common iliac veins causing secondary thrombosis and vessel occlusion. Chemotherapy and anticoagulant treatment resulted in mild thrombocytopenia and a prolonged prothrombin time, respectively, which exacerbated postoperative bleeding following surgical removal of a deep inguinal necrosis. After 6 days, bleeding combined with epistaxis was considered to be life threatening and anticoagulant reversal with recombinant factor VIIa was successfully performed. The patient has since achieved complete remission and subsequent antithrombotic therapy has resolved the vascular occlusion. Pediatr Blood Cancer 2007;49:332,335. © 2006 Wiley-Liss, Inc. [source]
