Peripherally inserted central catheters, or PICC lines, has now been successfully in use for many years, especially in the chemotherapeutic treatment of oncologic patients or in parenertal nutrition. The implantation of PICC lines is mostly performed under x-ray (fluoroscopy). The aim of the clinical study is to assess the safety and the efficacy of the SHERLOCK-Systems eliminating the confirmatory chest x-ray exposure. Additionally, the SHERLOCK-System immediately confirms the PICC tip position even at the bedside of the patient, thus, saving costs and time.

Peripherally inserted central catheters, or PICC lines, are clinically used for many years in the treatment of patients, whereby the implantation occurs under x-ray/fluoroscopy. Female and male patients of legal age that have the medical indication for Power-PICC-Line catheter implantation can be screened for the study. These medical indications include the necessity of chemotherapy in the course of an oncological treatment or parenteral nutrition. The study objective is to test the efficacy and safety of the SHERLOCK system, evaluated by a monocentric, randomized-controlled study. The advantage for the participating patients lies in a reduced radiation exposure due to the discontinued final chest x-ray examination (fluoroscopy). Furthermore, the SHERLOCK system can be deployed directly on ward, at the patient's bedside leading to a cost and time saving. Recruited in- and outpatients (of legal age) with indication for Power-PICC-Line catheter implantation will be randomly assigned to one of the two arms (fluoroscopy or SHERLOCK). Depending on randomization, the Power-PICC implantation occurs either under fluoroscopy or with the SHERLOCK system. All related substances, measures or procedures are performed according to the clinical routine. The medical device is a fully integrated magnetic tracking and ECG-based peripherally inserted central catheter (PICC) tip confirmation technology applied on patients with normal sinus rhythm and placed through a peripheral vein. The Sherlock system is CE-certified since December 2011.

The referral of patients with indication to PICC-Line implantation at the institute of diagnostic and interventional radiology occurs through different departments of the University Hospital Jena. The patients are registered for radiological treatment and checked again by a radiologist if a PICC-Line implantation is indicated. If this is the case, the radiologist conducts an informed consent discussion with the patient about possible complications and risks during intervention and informs him also about a possible study. After signature of the written informed consent, the patient is included. On the intervention day, the patient is randomly assigned to one of the two study arms through RandomTool (Sherlock vs. fluoroscopy). According to randomization group, the PICC catheter is implanted (duration: 30 minutes) and eventually a chest x-ray (fluoroscopy) is performed to assess safety and efficacy.The intervention time from puncture to catheter placement is documented. After intervention, the patient is transferred back to the ward or sent home in hemodynamically stable conditions. The examination of the puncture site before discharge is performed by a ward physician or by the family doctor. 24 h after PICC-Line implantation, the treating physician is contacted and questioned about possible complications (catheter occlusion, haematoma, infection of the puncture site, arm vein thrombosis, pain, etc.), that are then thoroughly documented.
