Central venous catheters provide an important means of vascular access and are increasingly used. Catheter occlusion refers to the inability to infuse or withdraw fluids from a catheter and could be caused by either thrombotic or nonthrombotic origin. We report an unusual malfunction of double lumen central venous catheter due to kinking and bending of the catheter at the opening site of proximal lumen.

Central venous catheterization by Seldinger's technique uses a guidewire which may cause complications such as kinking, knotting and fracture. Fractured guidewire may lead to severe outcomes such as embolization, and removal of it may also cause problems such as vessel damage. We experienced a case of right internal jugular venous catheterization complicated by guidewire fracture entrapped in the central venous catheter, and its successful removal under fluoroscopic guidance using snare-loop. The patient recovered without any complications. When resistance is felt during insertion or withdrawal of the guidewire, force should not be applied to the guidewire and care should also be exercised when passing the tissue dilator over the guidewire. Clinicians should be aware of this rare complication and snare-loop technique could be considered as one of the methods for removal of the fractured guidewire.

Various complications of central venous catheterization have been reported, some of which are well-known, while others are described as a sporadic events. We experienced a case of left subclavian venous catheterization complicated by extravascular knotting, kinking, and entrapment of the guidewire and the guidewire was removed surgically. Although minimal resistance was encountered during guidewire insertion, the guidewire was advanced approximately 30 cm. Physicians should be aware of these rare potential complications when a guidewire is advanced if any resistance is encountered.

OBJECTIVE: To explore the application value of blunt separation method in the modified sytinger technology peripherally inserted central catheter (PICC) catheterization in the hemopathic patients. METHODS: One hundred and twenty cases of the hemopathic diseases used modified sytinger technology PICC catheterization were selected from January 2016 to July 2017 in our Hospital, and randomly divided into blunt and routine group, each with 60 patients. For the routine group, the routine longitudinal method was used to expand the skin, for the blunt group the blunt separation method was used to expand the skin. RESULTS: At the time point of 24 h after the blunt catheterization, the bleeding volume and exudation rate in the blunt group were significantly lower than those in the rouline group (P<0.05). At the 1, 3, 5 d after catheterization, pain visual analogue score (VAS) showed that the scores of blunt group were significantly lower than those of the routine group (P<0.05). in expanding skin, the successful rate of catheterization once in blunt group and routine group were not significantly different (P>0.05). CONCLUSIONS Compared with the longitudinal method, the blunt separation method has considerable skin expansion and sheath feeding effect on the modified sytinger technology PICC catheterization for the hemopathic patients. This method can effectively reduce the patient's catheter trauma and percolation, and is helpful to relieve the patients' pain symptoms, worthing for further clinical promotion.

J-guide wires have been widely used for central venous catheterization with the popularity of the Seldinger technique. However, many adverse sequelae of central venous catheterization have been reported. We report two cases of J-guide wire breakage during central venous catheterization. Venipuncture by a steel needle was easily achieved in each case. However, insertion of a J-guide wire was difficult to perform, and pulling out the guide wire from the steel needle was more difficult, which caused breakage of the core and the uncoiling of the spring coil of the guide wire. The tip of the guide wire was not cut off, and there were no complications. With the removal of the guide wire, weak resistance was felt that which was not supposed to be sufficient to cut off the guide wire. It was assumed that an inherent fault in the manufacturing process of the guide wire could lead to this type of breakage.

Guidewire-associated complications that occur during the process of central venous catheterization include its kinking, looping, knotting and breakage. The removal of a looped or knotted guidewire is problematic because it can cause vessel damage, major hemorrhage, or embolization of a fractured guidewire. We report a case of guidewire kinking and its successful removal under fluoroscopic guidance.

Pneumothorax is one of the most frequent complications of percutaneous central venous catheterization.Most significant pneumothoraces are easily detected on postcatheterization chest radiograph.However, we report a rare case of delayed tension pneumothorax detected 4 days after unsuccessful central venous catheterization via the infraclavicular subclavian vein, although initial postcatheterization and postoperative supine chest radiographs showed no active lesion.
