The [[endovascular technique]] is a safe and highly efficient alternative to surgical clipping for PcomA aneurysms with [[oculomotor nerve palsy]] (ONP)
((Chalouhi N, Theofanis T, Jabbour P, Dumont AS, Gonzalez LF, Starke RM, Gordon 
D, Rosenwasser R, Tjoumakaris S. Endovascular treatment of posterior
communicating artery aneurysms with oculomotor nerve palsy: clinical outcomes and
predictors of nerve recovery. AJNR Am J Neuroradiol. 2013 Apr;34(4):828-32. doi: 
10.3174/ajnr.A3294. Epub 2012 Oct 4. Review. PubMed PMID: 23042929.
)).

For the [[true posterior communicating artery aneurysm]] it is a safe and feasible procedure but may be associated with [[aneurysm recurrence]] in midterm follow-up, requiring close surveillance and potential retreatment
((Wang C, Zhao R, Chang X, Li Q, Fang Y, Hong B, Xu Y, Huang Q, Liu J.
Feasibility and midterm outcomes of endovascular embolization for true posterior 
communicating artery aneurysms. Neuroradiology. 2019 Aug 10. doi:
10.1007/s00234-019-02277-y. [Epub ahead of print] PubMed PMID: 31401724.
)).

Also in the presence of [[fetal posterior communicating artery]] using multiple strategies
((Chen Z, Niu Y, Tang J, Li L, Feng Z, Feng H, Zhu G. Endovascular treatment of 
posterior communicating artery aneurysms in the presence of the fetal variant of 
posterior cerebral artery. Interv Neuroradiol. 2015 Aug;21(4):456-61. doi:
10.1177/1591019915590532. Epub 2015 Jun 25. PubMed PMID: 26111986; PubMed Central
PMCID: PMC4757316.
)).

However, patients who present with severe [[SAH]] still have an overall poor prognosis. Partial [[coiling]] of the aneurysm and the [[parent artery]] is an attractive alternative treatment for patients who may not tolerate [[parent artery occlusion]]. Further study with a larger case series is necessary for validation of the durability and efficacy of this treatment
((Qin X, Xu F, Maimaiti Y, Zheng Y, Xu B, Leng B, Chen G. Endovascular treatment
of posterior cerebral artery aneurysms: a single center's experience of 55 cases.
J Neurosurg. 2017 Apr;126(4):1094-1105. doi: 10.3171/2016.1.JNS152447. Epub 2016 
Apr 22. PubMed PMID: 27104845.
