Persistent primitive trigeminal artery associated with posterior communicating artery aneurysm and hypoplastic vertebral artery

We report a patient who presented with headache due to diffuse subarachnoid hemorrhage. A four-vessel angiogram revealed a left posterior communicating artery aneurysm with fetal origin, persistent primitive trigeminal artery and hypoplastic vertebral artery on the same side. This association was considered coincidental and co-existence of a saccular aneurysm with an anatomical variation of intracranial vasculature is briefly discussed.     

A radial artery originating from the thoracoacromial artery

Purpose

The purpose of this case report is to report a rare vascular variation in the upper limbs because of its clinical importance and embryological implication.

Methods

During the educational dissection of a 73-year-old Korean male cadaver`s right upper limb, we found a variant branch which is originated from the thoracoacromial artery.

Results

The variant branch from the thoracoacromial artery ran to the distal forearm in the deep fascia. Because it finally coursed like the radial artery in the forearm and the palm, we defined the variant artery as superficial brachioradial artery (SBRA). In the cubital region a little below the intercondylar line, the brachial artery gave off a small communicating branch to SBRA, and continued as the ulnar artery.

Conclusions

We reported this unique variation and discussed its clinical and embryological implication.

     

Superficial ulnar artery terminating in a normal ulnar artery

Routine dissection of the left upper limb of an 86-year-old male cadaver showed a superficial ulnar artery that anastomosed with the ulnar artery. The superficial ulnar artery arose from the third part of the axillary artery, coursed distally over the flexor muscles of the forearm, and terminated by anastomosing with the ulnar artery in the distal third of the forearm. Arterial and neural variations were also observed on the contralateral side. The presence of a superficial ulnar artery is important clinically when raising forearm flaps in reconstructive surgery.

Superdominant right coronary artery with absent left circumflex artery

Noninvasive imaging of coronary artery disease is rapidly replacing angiography as the first line of investigation. Multislice CT is the non-invasive modality of choice for imaging coronary artery disease and provides high speed with good spatial resolution. CT coronary angiography in addition to detecting and characterising atherosclerotic coronary artery disease is also a good imaging tool for evaluating anomalies of coronary arteries. Superdominant right coronary artery with absent left circumflex artery is one such rare coronary artery anomaly which is well evaluated with multislice CT angiography. The authors report one such case of superdominant right coronary artery with absent left circumflex artery imaged with 64-slice MDCT.
