“…Esta variación tiene una frecuencia del 0,7 % al 5,4 % en la bibliografía consultada. Corresponde al remanente embriológico denominado vena yugulocefálica persistente (VYC), típica de primates no humanos, y reportada de manera esporádica en humanos (Jun et al, 2017;Latarjet & Ruiz Liard;Maalman et al;Novakov & Krasteva;Russo et al) Así mismo, la literatura describe casos en los que el AVC puede drenar también en la vena yugular interna (VYI) o directamente en la vena subclavia (VS), siendo esta última, la variación más frecuente (Kiev & Asif; Lau et al).…”

RESUMEN: Dentro de las disfunciones de los angioaccesos, la estenosis del arco de la vena cefálica (AVC) juega un papel significativo. Existen características anatómicas del AVC que explican, en parte, este fenómeno. Todo esto obliga a un conocimiento profundo del AVC y sus principales variantes. Se disecaron 43 (n=43) axilas de cadáveres adultos fijados en solución en base a formol. Se registró: longitud del AVC (LAC), angulación del AVC respecto a la vena cefálica (AAC), tipo de terminación (simple o múltiple), presencia de afluentes y su número. LAC promedio 31,6 mm (rango 17-46 mm); AAC promedio 128,95° (rango 65-165°). En cuanto al tipo de terminación 41 (95,3 %) fueron simples, mientras que 2 casos (4,7 %) fueron de forma múltiple. Respecto a los afluentes, se encontraron en 42 de los casos (90,5 %). Se encontraron válvulas en 27 (62,8 %) de los casos. La longitud promedio del AVC fue de 31,6 mm, se dispuso en la mayoría de los casos en ángulo obtuso, presentando en la mayoría de los casos terminación de tipo simple. Además, en el 90,5 % se encontró afluentes que se agotaban en el AVC y en más de la mitad de los casos se encontraron válvulas. Se discuten las implicancias de estos hallazgos en la génesis de la disfunción de angioaccesos.

“…The cephalic vein (CV) passes between the deltoid and pectoralis major muscles (deltopectoral groove) and through the deltopectoral triangle, where it empties into the axillary vein and continues to the subclavian vein under the clavicle. CV has recently been used in invasive clinical procedures such as cardiovascular implantable electronic device implantation [5,7,12,15,28] and catheterisation [17], since it is remarkably constant superficial structure in the upper arm and axilla [34], has large size enough to facilitate easy cannulation [3,16,17], and known to have lower risk of injury to neighbouring structures than axillary vein puncture [29].…”

Two different variants of the jugulocephalic vein with supraclavicular course

et al. 2020

The jugulocephalic anastomosis is a rare anatomical variant which normally undergoes atrophy during embryonic development. We found 2 cases of the jugulocephalic vein variant with supraclavicular course in Korean male cadavers. In a 50-year-old cadaver, the right cephalic vein ascended anterior to the clavicle, and terminated into the external jugular vein as well as to the axillary vein through a classic branch. In a 76-year-old cadaver, the left cephalic vein ascended supraclavicular course without any branch to the axillary vein, and terminated to the external jugular vein. We discussed the embryological explanation as well as its frequency since this jugulocephalic vein variant could cause unpredicted danger during clinical procedures.

“…However, some anatomic variants exist and include the bifid and trifid arch (4). Jun et al reported a rare anatomic variant of a single-conduit supraclavicular cephalic arch draining directly into the external jugular vein, and this case involved recurrent stenosis of the cephalic arch and external jugular vein (6). We suppose that idiopathic CAS combined with congenital cephalic arch anomalies can induce rare retrograde venous reflux into the ipsilateral external jugular vein and can subsequently lead to SOV enlargement, as observed in our case.…”

A 72-year-old woman presented with progressive nonpainful edema and erythema of the left periorbital area in recent months. Medical history was notable for vasculitis-related endstage renal disease that had been diagnosed 6 years ago. She underwent a procedure that involved creating a brachiocephalic arteriovenous fistula (BCAVF) in the left forearm 2 years ago for the purpose of regular hemodialysis. She received percutaneous angioplasty with a balloon dilatation catheter because of repeat stenosis in the left cephalic arch at that time.At the time of presenting to the hospital, her visual acuity was 20/63 in both eyes. Neither relative afferent pupillary
