AbstractCentral venous catheter insertion is a commonly performed procedure in the operating room and intensive care unit. It is associated with many complications, some of which may be life-threatening. We report here an accidental insertion of a hemodialysis catheter into the brachiocephalic trunk, which was successfully removed by an endovascular technique.

Central venous disease (CVD) is a serious complication in hemodialysis patients. Neurological manifestations are rare. We describe a female with end-stage renal disease with throbbing headache accompanied by paresthesia, weakness, and abnormal posture of her right hand during dialysis sessions. Motor symptoms completely resolved after each dialysis session, although the headaches persisted for several hours. No neurological deficit was evidenced on physical examination. Digital subtraction angiography identified an incomplete thrombosis of the left brachiocephalic vein with retrograde flow in the internal jugular vein, sigmoid sinus, and transverse sinus on the left side. This case illustrates that cerebral venous congestion due to CVD can produce neurological symptoms. Furthermore, we systematically review the literature to identify the characteristics of the cases described so far. This allows clinicians to know the entity and have a high index of suspicion in a hemodialysis patient who develops neurological symptoms.

Patients with muscle invasive bladder cancer have a generally known 5-year overall survival of approximately 58% with neoadjuvant chemotherapy (NAC). During the last decades, addition of Cisplatinum-based NAC in fit patients prior to radical cystectomy (RC), has significantly improved OS, compared to RC only. However, some published studies following NAC addition, describe an intermediate risk increase of thromboembolic events (TEEs). Placement of central venous access (CVA) before NAC has also been suggested as being a potential risk factor for thrombosis. We present a combination of images and cases from the Northern Swedish health region where three patients developed venous TEE after CVA placement for NAC-administration and found that the time until curable RC was prolonged circa one month each, with an addition of one RC cancelled. These are serious events and to our knowledge, there are no current guidelines on prevention of TEE before RC. The aim with this report was to provide examples of these events and conclude that further prospective trials are warranted on prevention and future guidelines regarding venous anticoagulant treatment for TEE that occur pre-RC in NAC-patients.

Background To prevent recurrence of medical accidents, the Medical Accident Investigating System was implemented in October 2015 by the Japan Medical Safety Research Organization (Medsafe Japan) to target deaths from medical care that were unforeseen by the administrator. Medsafe Japan analyzed the 10 cases of central venous catheterization-related deaths reported in the system and published recommendations in March 2017. However, the particular emphasis for the prevention of central venous catheterization-related deaths is unclear. Methods This study aimed to identify the recommendation points that should be emphasized to prevent recurrence of central venous catheterization-related deaths. We assessed central venous catheterization in 8530 closed-claim cases between January 2002 and December 2016 covered by the medical insurer Sompo-Japan. Moreover, we compared central venous catheterization-related death in closed-claim cases with death in reported cases. Results The background, error type, anatomic insertion site, and fatal complication data were evaluated for 37 closed-claim cases, of which 12 (32.4%) were death cases. Of the 12 closed-claim cases and 10 reported cases, 9 (75.0%) closed-claim cases and 9 (90.0%) reported cases were related to vascular access. Among these, 5 closed-claim cases (41.7%) and 7 reported cases (77.8%) were related to internal jugular vein catheterization (p = 0.28). Coagulopathy was observed in 3 (60.0%) of 5 closed-claim cases and 6 (85.7%) of 7 reported cases. Conclusions The risk of internal jugular catheterization in patients with coagulopathy must be carefully considered.

Introduction: Intradialytic hypotension is a common complication of haemodialysis, but uncommon in peritoneal dialysis (PD). This may be due to lower ultrafiltration rates in PD compared to haemodialysis, allowing for sufficient refilling of the blood plasma compartment from the interstitial volume, but the underlying mechanisms are unknown. Here we assessed plasma volume and hemodynamic alterations during experimental PD with high versus low ultrafiltration rates. Methods: Experiments were conducted in two groups of healthy Sprague-Dawley rats: one group with a high ultrafiltration rate ( N = 7) induced by 8.5% glucose and a low UF group ( N = 6; 1.5% glucose), with an initial assessment of the extracellular fluid volume, followed by 30 min PD with plasma volume measurements at baseline, 5, 10, 15 and 30 min. Mean arterial pressure, central venous pressure and heart rate were continuously monitored during the experiment. Results: No significant changes over time in plasma volume, mean arterial pressure or central venous pressure were detected during the course of the experiments, despite an ultrafiltration (UF) rate of 56 mL/h/kg in the high UF group. In the high UF group, a decrease in extracellular fluid volume of −7 mL (−10.7% (95% confidence interval: −13.8% to −7.6%)) was observed, in line with the average UF volume of 8.0 mL (standard deviation: 0.5 mL). Conclusion: Despite high UF rates, we found that plasma volumes were remarkably preserved in the present experiments, indicating effective refilling of the plasma compartment from interstitial tissues. Further studies should clarify which mechanisms preserve the plasma volume during high UF rates in PD.

AbstractSome hemodialysis patients are not suitable for creation of an arteriovenous fistula (AVF) or arteriovenous graft (AVG). However, they can receive a tunneled cuffed central venous catheter (tcCVC), but this carries risks of infection and mortality. We aimed to evaluate the safety and effectiveness of brachial artery transposition (BAT) versus those of tcCVC. This retrospective study evaluated hemodialysis patients who underwent BAT or tcCVC placement because of severe heart failure, hand ischemia, central venous stenosis or occlusion, inadequate vessels for creating standard arteriovenous access, or limited life expectancy. The primary outcome was whole access circuit patency. Thirty-eight patients who underwent BAT and 25 who underwent tcCVC placement were included. One-year patency rates for the whole access circuit were 84.6% and 44.9% in the BAT and tcCVC groups, respectively. The BAT group was more likely to maintain patency (unadjusted hazard ratio: 0.17, 95% confidence interval: 0.05–0.60, p = 0.006). The two groups did not have significantly different overall survival (log-rank p = 0.146), although severe complications were less common in the BAT group (3% vs. 28%, p = 0.005). Relative to tcCVC placement, BAT is safe and effective with acceptable patency in hemodialysis patients not suitable for AVF or AVG creation.
