چکیده
Manuscript received February 19, 2016; accepted February 25, 2016. angiography showed competitive follow in the distal left anterior descending coronary artery (Figure 1, Online Video 1). However, LIMA could not be visualized despite multiple angiographic images of left subclavian artery. Aortic arch angiography showed an artery coming off the aortic arch just distal to the origin of the subclavian artery (Figure 1, Online Video 2).

Case Report: Absence of Thyrocervical Trunk
The thyrocervical trunk most commonly arises from the upper portion of the first segment of the subclavian artery, close to the medial edge of the scalenus anterior muscle and after short distance is divided to the inferior thyroid, transverse cervical, and suprascapular artery. This study reports important variations in branches of the thyrocervical trunk in a singular fema...
متن کاملAbnormal origin of the left internal thoracic artery detected only by computed tomography.
The origins of the branches of the subclavian artery are known to be variable. We present the case of a 55-year-old man whose coronary artery bypass surgery necessitated the use of the internal thoracic artery as he lacked other suitable venous conduits. The left internal thoracic artery appeared to be absent on subselective subclavian angiography. Computed tomographic angiography revealed a pr...

Among the present classes of calcium channel blockers, dihydropyridine derivatives are widely used in the therapy of hypertension, angina pectoris and the other cardiovascular diseases. Since the prototype of dihydropyridine derivatives, nifedipine, does not have the optimum pharmacokinetic and pharmacodynamic characteristics, several attempts have been made to synthesize other drugs in this ...
متن کاملAbnormal origin of internal thoracic artery from the thyrocervical trunk: surgical considerations
An unusual case of left internal thoracic artery (ITA) origin from the thyrocervical trunk (TCT) was detected during routine cadaver dissection. The variability of origin and course of ITA has less or more frequently been documented in the literature. However, the ITA origin from the TCT on the left side has been detected less commonly, making its dissection and preparation during coronary arte...
متن کاملThe variations of the subclavian artery and its branches.
This study reports important variations in branches of the subclavian artery in a singular cadaver. The origin of the left vertebral artery was from the aortic arch. On the right side, no thyrocervical trunk was found. The two branches which normally originate from the thyrocervical trunk had a different origin. The transverse cervical artery arose directly from the subclavian artery and supras...
