summary
The knowledge of cephalic vein variation would aid proper identification and
prevent error in surgical emergencies. The path, distribution, and termination
of the cephalic vein in relation to the deltopectoral triangle were studied in
twenty formalin-embalmed cadavers. Results show the bilateral presentation of
the cephalic vein in all the shoulders examined. Thirty-seven (37) cases
presented with a superficial and lateral course of the cephalic vein in the
deltopectoral groove, while the rest three cases presented a deep course. Of
these 37 cases with the superficial course, two cases ascended anteriorly and
above the clavicle and drained into the external jugular vein in the neck.
Another case presented a cephalic vein that ascended anteriorly and then above
the clavicle and drained into an unnamed vein in the neck. In one case, the
cephalic vein ascended superficially in the deltopectoral groove and laterally
in the deltopectoral triangle. In one bilateral pattern, the cephalic vein in
the deltopectoral triangle drained into the axillary vein. In all the three
cases where the cephalic vein ascended deep within the deltopectoral groove,
they terminated deep in the deltopectoral triangle. In one of these, the
cephalic vein received a tributary that originated from a venous network beneath
the deltoid muscle and then drained into athe xillary vein, deep in the
deltopectoral triangle. In the other two cases, the cephalic vein gave a
tributary to the axillary vein and continued deep and medially in the
deltopectoral triangle, passed below the clavicle and drained into the
subclavian vein. The knowledge of these variations of
the cephalic vein is essential to clinicians and
surgeons for venous access during emergencies and surgery.
