Non-selective abdominal angiograms showed no arterial extravasation but selective right third lumbar artery injection revealed active extravasation from a dorsal branch
The dorsal branch
of the radial artery, which is the scaphoid's main blood supply, enters through the dorsal ridge and supplies 80% of the scaphoid in a retrograde manner.
Pygofer dorsal appendage movably articulated, bifurcate at base, dorsal branch
longer than ventral branch, extended beyond apex of lobe.
Notably for the ulnar nerve, the use of only the two points supplied by the dorsal cutaneous branch detects abnormality in 56% of nerves (78/140) whereas use of three points on palm (Method A) detects abnormality in 27% of nerves (38/140), showing that the dorsal branch
of the ulnar is more frequently impaired than the palmar branch.
1 and 2 and 3: Av) had its origin from the caudoventral angle of the ganglion by three separated branches; the dorsal branch
(2.5 [+ or -] 0.13 mm in width) is the thicker one (Figs.
The dorsal branch
of these branches was connected with another ganglion (Fig.
Doppler parameters showed a reduction of peripheral blood resistances and a progressive reduction in resistance of the blood flow in the dorsal branch
of the prostatic artery.
There was also an interlobar artery in one of the left kidneys SD, originated from the dorsal branch
. It separated the ventral mid zone (Figures 1 and 6).
Rare anatomical variations described by various authors are; failure of the middle third of the posterior interosseous flap;14 absence of anastomosis between recurrent dorsal branch
of anterior interosseous artery and posterior interosseous artery at the level of middle third of the posterior forearm;21 narrowing of PIA in the middle third of forearm;13 and termination of PIA in the middle third of the forearm.16 However, we did not find any anatomical variation in our study of 53 PIA flaps.
DBUN dorsal branch
of ulnar nerve; SBUN superficial branch of ulnar nerve; KA Kaplan's anastomosis.
Usually the first part of vertebral artery develops from proximal part of dorsal branch
of seventh cervical intersegmental artery proximal to postcostal anastomosis.
