Blog Article

Background: Intracerebral hemorrhage (ICH) after a rete middle cerebral artery (MCA)-related rupture of a distal lenticulostriate artery (LSA) aneurysm is extremely rare, only five cases have been reported in the previous literature.Case descriptions: In this study, we report two cases of a rete MCA-related rupture wherein LSA aneurysms were treated with endovascular and medical therapy.A 69-year-old woman with a right rete MCA developed a right putaminal hematoma due to the rupture of a right dilated LSA Girls Jackets aneurysm.As the parent LSA arose proximal to the abnormal arterial network, we first planned endovascular aneurysmal embolization.However, due to penetration of the parental artery with a microwire, we operated on the parental artery occlusion.

The aneurysm disappeared after treatment without any ischemic lesion in the right cerebral hemisphere.The second case was a 72-year-old woman with a right putaminal hematoma.As the LSA was thin and arose from the anomaly Cyclist Accessories - Body Armor itself, the patient was treated conservatively without surgical intervention.Angiography performed 14 days after onset demonstrated spontaneous disappearance of the aneurysm.Conclusion: There is no common consensus on treatment strategies for rete MCA-related distal LSA aneurysms.

We propose that parental artery occlusion and conservative observation can be treatment options for this rare type of aneurysm.
