A Cadaveric Study of Radial Artery and Cephalic Vein in Forearm and Hand: A Guideline for Radio-cephalic Arteriovenous Fistula Planning

Introduction: The creation and maintenance of uninterrupted Haemodialysis (HD) is dependent on the quality reliability vascular access. native Radio-cephalic Arteriovenous Fistula (RCAVF) access choice for HD in patients with end stage renal diseases. A thorough understanding anatomy critical selecting site RCAVF that provides flow rates necessary development an optimal outflow vein. widespread use doppler ultrasound has facilitated identification vessels are suitable fistula construction. Aim: To analyse surgical radial artery cephalic vein front forearm dorsum hand, pertinent to planning. Materials Methods: cross-sectional cadaveric 30 formalin preserved upper limbs specimens adult human cadavers was done Department Anatomy, Hamdard Institute Medical Sciences, New Delhi, India, (n=22 limbs) from August 2016 April 2018 Government Greater Noida, Uttar Pradesh, India (n=8 November 2019. external diameter artery, distance between were measured at mid forearm, wrist Anatomical Snuff Box (ASB). Measurements taken sliding vernier caliper accuracy 0.01 mm. All measurements tabulated separately right left-side. data analysed using Microsoft excel. Descriptive statistics like mean, standard deviation (SD) range evaluated all parameters collected. paired t-test applied compare left-side measurements. Results: Amongst analysed, 3±0.26 mm right-side 2.87±0.24 left- side 2.5±0.59 2.9±0.33 ASB. 2.5 ±0.59 which minimum maximum (4.02±0.76 4.2±0.71 left hand). Conclusion: formation ASB may give better results as closer compared midforearm reasonable diameter. Additionally, it would also provide long segment arterialization.
