“…This has been reported in many cases with hypoplasia in the BA proximal segments. 11 Despite these calibration differences in the PCoA, no significant changes in VA calibration, VA FV, and velocities were observed, which may indicate that the blood in the posterior circulation was largely used in the blood supply of the posterior fossa. A decrease in the flow rate may explain vertebrobasilar ischemia and presyncope.…”

Objectives: It is important to know the range of normal vertebral artery (VA) flow volume. Diminished VA flow volume is associated with vertebrobasilar insufficiency. The study aim was to investigate the relationship between the posterior communicating artery (PCoA) calibration and the VA flow parameters, in patients with no underlying cerebrovascular disease, below 50 years of age. Materials and Methods: The study population consisted of 102 cases below 50 years of age. The basilar artery (BA), internal carotid artery (ICA), and the PCoA calibrations were measured with magnetic resonance angiography. The VA flow parameters (maximum systolic velocity, end-diastolic velocity, mean velocity, VA flow volume, and VA calibration) were measured with duplex sonography. Results: There was no statistically significant difference between these two imaging groups, in terms of VA Vmax, VA flow volumes, VA calibrations, and BA calibrations. However, the mean right ICA and mean left ICA calibrations were significantly higher in group 2 than group 1 ( P < .01). There was no significant correlation between mean PCoA calibration and mean Vmax, mean calibration, and the total flow volume of vertebral arteries. Conclusion: The findings indicate that the VA flow rate may be relatively maintained, regardless of PCoA measurements in this study.

“…Similar to the persistent PTA, the tentorial artery arises from the cavernous ICA directly and without branches. PTA is the most common variant of carotid-vertebrobasilar anastomoses, with an estimated prevalence of 0.1-0.6% [8]. While classic persistent PTA extends from ICA to the basilar artery, PTA variant continues as a cerebellar artery without basilar connection [9].…”

A unique temporary collateral pathway between carotid-vertebrobasilar arteries in a carotid dissection patient

Background: In adults, the anastomosis between carotid and vertebrobasilar arteries is usually the posterior communicating artery, sometimes the primitive trigeminal artery. In this case, the basilar artery fed the internal carotid artery through the pontine-to-tentorial artery anastomosis after severe stenosis from traumatic carotid dissection. Case presentation: A 32-year-old female was diagnosed with ischemic stroke caused by traumatic carotid artery dissection. Aspirin (100 mg/day) and clopidogrel (75 mg/day) were prescribed. Digital subtraction angiography performed 6 days after stroke onset showed a dissection in the cervical segment of left internal carotid artery with severe local stenosis, and a collateral pathway from BA to the cavernous segment of internal carotid artery through the lateral pontine and tentorial artery. Without interventional therapy, clinical symptoms improved significantly within 10 days after onset. At 3-month follow-up, left common carotid artery angiography showed the stenosis had been significantly improved with a residual aneurysm. There was no collateral pathway between carotid-vertebrobasilar arteries, and a residual small artery originated from the posterior vertical segment of cavernous internal carotid artery. The small artery was clearly visualized by 3-dimensional rotational angiography and identified the tentorial artery. Conclusion: To the author's knowledge, this is the first report of a collateral pathway between carotid vertebrobasilar arteries through the pontine-to-tentorial artery anastomosis. Meanwhile, tentorial artery origination directly from the cavernous segment of internal carotid artery is rare and easily mistaken for persistent primitive trigeminal artery. 3dimensional rotational angiography can provide sensitive and accurate diagnostic assessment of the small artery, and may be a useful tool for screening of abnormal small arteries.

“…Among these 7 cases, there was a total of 28 aneurysms. Of these 28 aneurysms, 24 were treated with open surgery; 3 aneurysms were left untreated and followed with observation; 1 aneurysm was treated with interventional therapy. 7,[35][36][37][38][39][40] Because PPTA aneurysms are rare and there is a paucity of relevant research, the rupture risk of PPTA aneurysms remains unknown.…”

“…23 In addition, the incidence of PPTA with intracranial aneurysms has been reported to be 22% and 42% in two recent studies with a sample size of 2410 and 2488 cases, respectively. 24,25 The high incidence of PPTA with intracranial aneurysms in the two studies may be caused by the above-mentioned selection bias, and increased sample size may reduce the selection bias to some extent. In a study which included over 16,000 cases (the largest sample size reported in the literature as we know), magnetic resonance angiography was performed to analyse cases of PPTA.…”

The primitive trigeminal artery is an anastomotic vessel of the carotid–basilar artery system that occurs only transiently during the embryonic period. Persistent primitive trigeminal artery occurs in approximately 0.1–0.6% of the population. Here, we report the case of a 60-year-old woman with Fisher II grade subarachnoid haemorrhage. Computed tomography angiography demonstrated a lateral, Saltzman type I persistent primitive trigeminal artery with three cerebral aneurysms, including one anterior communicating artery aneurysm, one suspicious right anterior choroidal artery aneurysm and one distal basilar artery aneurysm supplied by the persistent primitive trigeminal artery. All three aneurysms were treated with coil embolisation. At the 8-month follow-up, the anterior communicating artery aneurysm had a neck remnant, the other two aneurysms exhibited complete occlusion. Persistent primitive trigeminal artery with multiple cerebral aneurysms is extremely rare, and only seven cases of persistent primitive trigeminal artery with multiple cerebral aneurysms have previously been reported in publications that included information on treatment. Most aneurysms were treated by open surgery. This is the first report of coil embolisation treatment of multiple aneurysms in persistent primitive trigeminal artery patients with follow-up results, and provides relevant and valuable information about the persistent primitive trigeminal artery and the endovascular treatment of multiple aneurysms in persistent primitive trigeminal artery patients.
