| Description: | Aims:
Evaluation of the capacity of the Angio-CT and the Angio-MRI to identify and
measure the transverse artery of the carpus, identification of the modal and variant
arrangement as well as the morphometry of the large anterior arterial trunks of the
forearm, the superficial and deep palmar arches and the common digital arteries.
Methods:
A total of 52 cases were studied retrospectively, distributed as follows, 12
dissection on anatomical subjects (cadavers), 29 Angio CT and 11 Angio-MRI. The
analysis concerned first to identify, calculate the diameter and length of the radial branch
of the transverse artery of the carpus used in pedunculated grafts of scaphoid
osteonecrosis and Kienboeck’s disease. Secondly, the modal and variant identification with calculation of the diameters
of the ulnar, radial, anterior interosseous, and median artery in dissection and CT, as
well as the complete or incomplete character of the superficial palmar arch, the
arrangement of the deep palmar arch and the modal birth or not of the common digital
arteries on the three modalities (dissection, CT, MRI). The dissections on anatomical subjects were illustrated by taking photos and a
schematic transcription, the analysis of the imaging examinations was done on
Workstations and special DICOM viewers with an image capture and schematic
transcription.
Results:
The radial branch (RR) of the transverse carpal artery was identifiable on all
dissected subjects 100%, 58% on CT versus 18% on MRI, the morphometry including
the diameter of the RR was 0.45 +/- 0.06, 0.42 +/- 0.06, 0.45 +/- 0.06 mm, and the length
of the RR 30.8 +/- 2, 28.2 +/- 2, 27.5 +/- 0.5 respectively on the dissection, CT and MRI. The exploration of the anterior anti-brachial arterial axes on dissection and CT
presented relatively the same frequencies and the same type of variant for the radial,
ulnar, anterior interosseous artery, the median artery and the variants of its summer
origin. More detected in CT (75%) than in dissection (16%), the classification and
identification of the complete and incomplete superficial palmar arch presented very
close frequencies between the three modalities with an incomplete character of 41% in
dissection, 38% in CT and 45% in MRI, the birth of the common digital arteries
followed this distribution of their origin of the superficial palmar arch. The diameter of
these different vessels showed a connection between two or even three techniques. |
