Incidence of Deep Vein Thrombosis on Central Venous Catheters in the Post Operative Period of Carcinologic Surgery

Interest of Doppler Ultrasound for the Assessment of Incidence of Deep Vein Thrombosis on Central Venous Catheters in the Post Operative Period of Carcinologic Surgery

The objective is to determine the incidence of thrombosis on central venous catheters in patients hospitalized in a surgical critical care unit, in the immediate postoperative period of urological or digestive carcinological surgery, and receiving parenteral nutrition.

The post operative period, wich is a critically ill condition, and history of cancer are related to a high risk of venous thrombosis. Catheter is one of the most common complication of parenteral nutrition and is also related to thrombosis.

The combination of theses conditions increases the risk of venous catheter thrombosis. , Since, there is no data evaluating this risk nowadays, the objective of this study is to determine the incidence of thrombosis on central venous catheters in patients hospitalized in a surgical critical care unit, in the immediate postoperative period of urological or digestive carcinological surgery, and receiving parenteral nutrition.

Inclusion Criteria:

• Hospitalization in surgical intensive care in the immediate post-operative period
• surgery for cancer
• central venous catheter placement for parenteral nutrition
• written consent dated and signed before doppler examination

Exclusion Criteria:

• patient < 18 years old
• pregnancy
• surgery with no indication for parenteral nutrition on central venous access
