Results: LRNVC after prolonged lithotomy position during colorectal surgery can be classified into vascular, neurological and neurovascular combined. Compartment syndrome (CS) is the most common clinical presentation. Seven case reports and 10 case series on 34 patients (27 men, 6 women) with CS have been reported. Risk factors included the lithotomy position and duration of surgery of more than 4 h.
RESULTS: Among all central venous catheterizations (n=1,599), the subclavian route was used 981 times (61.4%). There were 51 misplacements of SCV catheters (5.2%) during the study period. There were no differences in the sex, age, blood pressure, and diagnosis between the two groups. The CTA values were 28.5°±7.3° and 22.6°±6.3° in the misplacement group and control group, respectively (95% confidence interval, 3.6 to 8.1; P<0.001).
CONCLUSION: In this study, the CTA was found to be 5.9° larger in the misplacement group than in the control group. Assuming that CTA indicates the shoulder position, our findings suggest that the chance of SCV catheter misplacement may be reduced by avoiding the shoulder elevated.
