Labelled as T formation with triradius in the center of the drawing classified as half of ulnar and half of radial loop
This was due to an anomaly of the radial artery such as a radial loop
, high take of radial artery or due to a small caliber vessel.
Of the 13 failures, in 7 patients radial artery spasm occurred and in 6 patients the advancement of the guidewire within the aorta was not succeeded due to failure to negotiate brachial tortuosity (n = 3), radial loop
(n = 2), and aortic root elongation (n = 1).
Tented Loop--Formation with triradius in the centre of the drawing, which is classified as half of ulnar and half of radial loop
[topologically) and in the literature is denoted by T.
, ulnar loop, arches and whorls were recorded (Fig.
The radial loop
pattern were found to be absent in I, II, IV, V of left hand and digits V, III, II of right hand.
According to the side of opening of the curve loops may be ulnar loop or radial loop
is so called because the ridges flow or terminate in the direction of radius bone of the forearm.
The qualitative study included fingerprint patterns (arches, radial loops
, ulnar loops and whorls) and palmar patterns (Simian line and Sydney line).
Table 4 shows fall in the percentage of radial loops
in pulmonary tuberculosis patients (0.8%) as compared to normal (2.2%) Table 3 shows in left hand and 2.2% and 1.6% in right hand respectively.
Loops may be ulnar or radial loops
. The typical whorl is a generalized pattern.
