ABSTRACT
PURPOSE: To report the sequential placement of inferior vena cava filter (IVCF) and peripherally inserted central catheter (PICC) using the same upper extremity venous access. MATERIAL AND METHODS: This is a retrospective study that reviewed the medical records of 379 consecutive patients who underwent IVCF insertion during a 39-month period at our center. Of these 379 patients, 28 patients had sequential insertion of an IVCF and a PICC through the same upper extremity venous access. The same vein entry site was used for placement of the IVCF followed by PICC insertion. Data collected included: indication and duration of IVCF and PICC placement, access site location, complications, and the type of IVCF. RESULTS: IVCFs were placed for prophylactic purposes in 15 patients (53.6%) and therapeutic purposes in 13 patients (46.4%). Right upper extremity veins were used for venous access in 27 patients (96.4%): brachial (n=16), basilic (n=9), and cephalic (n=2). The left basilic vein was used in one patient (3.6%). IVCFs were temporary in 20 patients (71.4%) and permanent in 8 patients (28.6%). There were no procedural complications. The OptEase filter was used in 23 patients (82.1%) and the TrapEase filter was used in 5 patients (17.9%). CONCLUSION: Simultaneous IVCF and PICC insertion using the same upper extremity venous access was feasible and safe in our series. This combined technique provides the patient with central venous access for repeated blood collections and intravenous therapy.

AIM: To evaluate the influence of number and location of catheter shaft side holes regarding drainage efficiency in an in vitro model. MATERIALS AND METHODS: Three different drainage catheter models were constructed: open-ended model with no side holes (one catheter), unilateral side hole model (six catheters with one to six unilateral side holes), and bilateral side hole model (six catheters with one to six bilateral side holes). Catheters were inserted into a drainage output-measuring device with a constant-pressure reservoir of water. The volume of water evacuated by each of the catheters at 10-second intervals was measured. A total of five trials were performed for each catheter. Data were analysed using one-way analysis of variance. RESULTS: The open-ended catheter had a mean drainage volume comparable to the unilateral model catheters with three, four, and five side holes. Unilateral model catheters had significant drainage volume increases up to three side holes; unilateral model catheters with more than three side holes had no significant improvement in drainage volume. All bilateral model catheters had significantly higher mean drainage volumes than their unilateral counterparts. There was no significant difference between the mean drainage volume with one, two, or three pairs of bilateral side holes. Further, there was no drainage improvement by adding additional bilateral side holes. CONCLUSION: The present in vitro study suggests that beyond a critical side hole number threshold, adding more distal side holes does not improve catheter drainage efficiency. These results may be used to enhance catheter design towards improving their drainage efficiency.

The normal and post-traumatic appearances of the sub-talar joints are illustrated by means of a number of arthrograms. Special projections were used in order to demonstrate various parts of the joints. The mobility of the articulating bones and its relationship to the trabecular structure has been demonstrated. The mechanism of typical injuries in normal limbs, and in the presence of pes planus, is described. Radiological features of capsular injuries of the sub-talar joint have been studied by arthrography.

Contrast arrhrography has shown that this is a neccessary investigation in all cases of recurrent dislocation of the shoulder, in order to show the changes in the shoulder joint. The examination can be carried out in the early or late stages after trauma. The method is also indicated before carrying out reconstructive operations on the joint.
