It is difficult to insert long-term dialysis catheters after severe stenosis or occlusion of the internal jugular vein and innominate vein. We used REcanalisation and balloon-oriented puncture for Re-insertion of dialysis catheter in nonpatent central veins (REBORN) in seven patients with severe central venous lesions, and all patients were inserted with long-term dialysis catheters successfully. None had severe complications such as pneumothorax, hemothorax, or pulmonary embolism during operation. All catheters functioned well after postoperative follow-up of 2 months. REBORN provides a novel approach to establish difficult dialysis pathways.

OBJECTIVETo explore the clinical efficacy and safety of the early use of urokinase in the prevention and treatment on tunneled hemodialysis catheter related fibrin sheaths.

METHODSThirty-eight hemodialysis patients with tunneled central venous catheter and good catheter function were randomly divided into experimental group and control group. Urokinase was given after 3 days of indwelling catheter in the experimental group and after the onset of catheter dysfunction in the control group. The catheter function, mean blood flow and venous pressure of dialysis, coagulation, and side effects in the two groups were observed for 6 months.

RESULTSThe rates of catheter dysfunction on the arterial side were 0.65% and 2.71% in the experimental group and control group, respectively (P<0.05), with catheter dysfunction rates on the vein side of 0.92% and 2.41%, respectively (P<0.05). Catheter dysfunction occurred for the first time at 87.9 ± 24.1 days in the experimental group, and at 31.3 ± 11.5 days in the control group (P<0.05). The mean blood flow showed no significant difference between the two groups at 1 month after tube insertion (P>0.05), but was higher in the experimental group at 3 and 6 months after the tube insertion (P<0.05). The mean venous pressure in two groups was similar 1 and 3 months after tube insertion (P>0.05), but was significantly lower in the experimental group at 6 months (P<0.05). Compared with control group, the experimental group showed significantly prolonged prothrombin time (P<0.05) but similar rest coagulation parameters. No serious drug-related side effects occurred in these two groups.

CONCLUSIONEarly use of urokinase is safe and effective for prevention and treatment of tunneled hemodialysis catheter-related fibrin sheaths with minimal side effects.

While oral agents are currently suggested for the initial treatment of erectile dysfunction, penile prosthesis implantation (malleable or inflatable) is accepted as a third-line therapy if intracorporeal injection and intraurethral treatment fail as a secondary choice. Urethral erosion of the malleable penile prosthesis is a well-known complication, mostly due to the indwelling catheter. We report a case of urethral erosion of the malleable penile prosthesis after 23 years. The patient was a 45-year-old man without any underlying risk factors. He subsequently underwent a unilateral rod extraction under regional anaesthesia. It appears that urethral erosion of penile prostheses can appear at any time post operation, without any known facilitative factors and in any age group. Furthermore, simple office manoeuvres may not be possible in some patients.

INTRODUCTIONOne complication of autogenous arteriovenous fistula (AVF) for haemodialysis is the formation of a venous aneurysm.

CLINICAL PICTUREThe clinical picture is typically an expanding aneurysm leading to skin atrophy and ulceration with the risk of rupture and infection. Aneurysm also reduces the potential cannulation area.

TREATMENTThe cases described here used a surgical 'remodelling' technique involving complete skeletonisation of the venous aneurysm, reduction of lumen diameter and retention of vein wall using a Hegar dilatator to remodel a new fistula.

OUTCOMESix patients were treated using this method and the arterior venous shunt (AVS) was used for haemodialysis the following day. No recurrent aneurysm developed.

CONCLUSIONRemodelling of aneurysmal AVF is an effective and low-risk option for managing this kind of complication, allowing direct access for haemodialysis.

OBJECTIVE: To study the relationship of retaining time of tympanic ventilation tube and aural complications. METHOD: Three-hundred-five patients(659 ears)with otitis media with effusion (OME) received tympanostomy tube insertion. The tube were removed 6-36 months after tube insertion. Then aural complications were recorded in different tube retaining time, followed with a statistic analysis. RESULT: Fifty-five tubes of 29 patients were removed at 1-6 months after tube insertion, with spontaneous extrusion 3.4%, blocked tube 10.3%, intrusion into the middle ear 0, granulation tissue 0, cholesteatoma 0, otorrhea 6.9%, perforation 0. One hundred and ninety tubes of 96 patients were removed at 6-12 months after tube insertion , with spontaneous extrusion 7.3%, blocked tube 15.6%, intrusion into the middle ear 1%, granulation tissue 0, cholesteatoma 0, otorrhea 5.2%, perforation 0. Three hundred and eight tubes of 156 patients were removed at 12-24 months after tube insertion, with spontaneous extrusion 9%, blocked tube 12.8%, intrusion into the middle ear 1.3%, granulation tissue 1. 9%, cholesteatoma 0.6%, otorrhea 2.5%, perforation was 0. One hundred and sixty one tubes of 83 patients were removed at 24-36 months after tube insertion, with spontaneous extrusion 36.1%, blocked tube 53%, intrusion into the middle ear 6%, granulation tissue 3.6%, cholesteatoma 2.4%, otorrhea 2.4%, perforation 2.4%. CONCLUSION The occurrence of complication didn't increase with time going by when the ventilation tube retained less than two years. However, when the ventilation tube retained more than two years, the occurrence of spontaneous extrusion and blocked tube increased obviously.

Advanced cancer patients with refractory ascites often do not respond to conventional treatments including dietary sodium restriction, diuretics, and repeated large volume paracentesis. In these patients, continuous peritoneal drainage by an indwelling catheter may be an effective option for managing refractory ascites with a relative low complication rate. Peritoneal catheter-induced complications include hypotension, hematoma, leakage, cellulitis, peritonitis, and bowel perforation. Although bowel perforation is a very rare complication, it can become disastrous and necessitates emergency surgical treatment. Herein, we report a case of a 57-year-old male with refractory ascites due to advanced liver cancer who experienced iatrogenic colonic perforation after peritoneal drainage catheter insertion and was treated successfully with endoscopic clipping.

Migration of an implantable port catheter tip is one of the well-known complications of this procedure, but the etiology of this problem is not clear. We describe here a case of migration of the tip of a port catheter from the right atrium to the right axillary vein in a patient with severe cough. Coughing was suggested for this case as the cause of the catheter tip migration. We corrected the position of the catheter tip via transfemoral snaring.
