“…Recently, Wang et al reported 43 true PCoA aneurysms treated endovascularly. 49 In their study, 41 aneurysms originated from the proximal portion, 1 from the middle portion, and 1 from the distal portion. All aneurysms were successfully treated without complications; however, the recurrence rate was higher than usual.…”

Microsurgical Approach for True Posterior Communicating Artery Aneurysms: Literature Review and Illustrative Case

True posterior communicating artery (PCoA) aneurysms are rare. Although true PCoA aneurysms have been reported to be located close to the internal carotid artery, at the middle part of PCoA, or close to the posterior cerebral artery; the best surgical approach to treat true PCoA aneurysms in each location remains unclear. We conducted a literature review using data from PubMed. Data on demographics, location, and projecting direction of the aneurysm, surgical approach, and surgical complications were collected. A total of 47 true PCoA aneurysms were included. Twenty-nine aneurysms originated from the proximal portion, 10 from the middle portion, and 6 from the distal portion; there were two giant aneurysms. The ipsilateral pterional approach was used for 37 true PCoA aneurysms (27 in proximal portion, 8 in middle portion, and 2 in distal portion of PCoA). The anterior temporal approach was used for two distal-portion aneurysms and one giant aneurysm. The anterior subtemporal approach was used for one distal-portion aneurysm. The subtemporal approach was used for two middle-portion aneurysms and one giant aneurysm. The contralateral pterional approach was used for two proximal-portion and one distal-portion aneurysms. Although most true PCoA aneurysms can be treated by the pterional approach, other means such as anterior temporal and subtemporal approaches can be applicable for aneurysms in the middle and distal portions of the PCoA or giant aneurysms. Surgeons should select an appropriate approach for each aneurysm while considering the advantages and disadvantages of each technique.

“…Endovascular coil occlusion with or without stent assistance has been shown to be safe and efficacious in saccular TPcomA aneurysms (Liu et al 2019). Wang et al (2019) successfully treated 42 patients with 43 TPcomA aneurysms using coil occlusion, and reported an 18% rate of aneurysm reoccurring and therefore requiring re-coiling. None of the aneurysms treated by stent-assisted coil occlusion significantly recanalized.…”

Back in 1998, a then 44-year-old male patient presented with a left hemispheric minor ischemic stroke of undefined cause and was diagnosed by DSA with a small, right-hand asymptomatic yet partially thrombosed true posterior communicating artery (TPcomA) aneurysm. The patient failed to regularly attend the assigned follow-up clinical and crosssectional imaging examinations. In 2016, 18 years after the first DSA examination, the patient presented with progressive left-hand hemiparesis and mild fluctuating central facial nerve palsy. Cranial non-contrast-enhanced computed tomography (NCCT) revealed the presence of a large lobulated and partially thrombosed right-hand TPcomA aneurysm. The thrombotic material in the aneurysmal sac was exerting a local mass effect on the thalamus and brainstem. Contralateral ischemic changes in the left-hand capsular region were also noted. Diagnostic angiography confirmed that the lobulated aneurysm originated from the right-hand "fetal" PcomA itself. In 1998, as well as in 2016, the patient clearly rejected all the treatment options offered. Another 2 years later, the patient presented with a worsening of his left-hand hemiparesis. A cranial MRI and the following DSA examination confirmed that the aneurysm had been progressively growing over the past two
