ABSTRACT
BACKGROUND: Surgical venous cutdown is a method for totally implantable venous access device (TIVAD) insertion. The main drawback of this technique is its higher failure rate when compared with the percutaneous approach, which is mostly related to anatomic variations of the cephalic vein. The aim of this study was to assess preoperative ultrasound imaging as a tool to predict cephalic vein cutdown failure for TIVAD insertion. METHODS: Ultrasound and operative reports of a cohort of patients undergoing TIVAD insertion by cephalic vein cutdown were reviewed. Ultrasound venous (vein visibility, diameter, length, subcutaneous depth, vein path, and subclavian junction visibility) and patient variables were tested by logistic regression as predictors of TIVAD insertion failure. RESULTS: One hundred sixty consecutive patients underwent cephalic vein cutdown for attempted TIVAD insertion. An inability to visualize the vein on the preoperative ultrasound examination (odds ratio, 4.39; 95% confidence interval, 1.57-12.30; P < .05) and depth of the vein (odds ratio, 1.07; 95% confidence interval, 1.00-1.15; P = .042) were predictors of failure of TIVAD insertion by cephalic vein cutdown. CONCLUSIONS: Preoperative ultrasound examination allows identifying patients at risk of failure of TIVAD insertion by cephalic vein cutdown. Preoperative ultrasound examination constitutes an efficient tool for choosing the most appropriate surgical approach and improving patient comfort.

Biliary infections are a common cause of emergency department visit, usually of benign evolution but that can sometimes progress rapidly to a life-threatening emergency.The mainstay of treatment of acute cholecystitis is urgent laparoscopic cholecystectomy, performed in 72 hours.Antibiotic treatment is often sufficient for the initial treatment of mild cholangitis. A percutaneous or endoscopic biliary drainage must be done urgently in case of severe presentations or if the patient doesn't respond to conservative treatment. The definitive treatment of the cause of cholangitis, will be performed in a second time.
Les infections de la vésicule et des voies biliaires sont un motif fréquent de consultation aux urgences. Leur évolution est le plus souvent bénigne, mais elles peuvent parfois devenir rapidement une urgence vitale.Le pilier du traitement de la cholécystite aiguë est la cholécystectomie laparoscopique en urgence, réalisée dans un délai inférieur à 72 heures.L'antibiothérapie est souvent suffisante pour le traitement initial de Ia cholangite simple. Un drainage biliaire percutané ou endoscopique doit être effectué en urgence pour une cholangite sévère ou en cas de non-réponse au traitement conservateur. Le traitement définitif de la cause de la cholangite sera pratiqué dans un deuxième temps.
