[Three Cases of Esophageal Submucosal Hematoma after Coiling for Unruptured Cerebral or Intracranial Aneurysms].

We report three cases of esophageal submucosal hematoma after treatment of unruptured intracranial aneurysms. All cases were in women with a mean age of 67.7 years. They were administered anti-platelet drugs before undergoing operations to deliver stents. All cases were administered general heparinization during the operation. All three cases developed sudden-onset hemoptysis or epigastric pain. The medical treatments included the temporary cessation or reduction of antiplatelet therapy and all cases were discharged with symptom cure and with the appearance of gastric intestinal fiber on computed tomography imaging. Esophageal submucosal hematoma has a good prognosis with medical therapy. We should consider the potential for esophageal submucosal hematoma after hemoptysis or epigastric pain after coiling of unruptured intracranial aneurysms that require antiplatelet or anticoagulant therapies.

Flow Diverter Therapy of a Giant Fusiform Vertebrobasilar Junction Aneurysm in a Child: Case Report.

The management of giant vertebrobasilar junction (VBJ) aneurysms is extremely challenging. Flow diverter (FD) therapy has become an important alternative to treat difficult intracranial aneurysms for both open surgery and conventional endovascular therapy. Herein, we report a rare case of a giant fusiform VBJ aneurysm in a child that is successfully treated with FD therapy.

Endovascular parent artery occlusion of proximal posterior cerebral artery aneurysms: a report of two cases.

We report two cases of proximal posterior cerebral artery (PCA) aneurysms treated with endovascular parent artery occlusion (PAO) with coils. In both cases, selective injection from the 4 F distal access catheter clearly showed the perforating arteries arising from the PCA. Case No 1, a 49-year-old woman, was successfully treated with preservation of a paramedian artery. Case No 2, a 54-year-old woman, was treated in the same manner. The patient underwent extensive thalamic infarction after the procedure because of paramedian artery occlusion. Endovascular PAO with coils is feasible for proximal PCA aneurysms; however, preservation of perforating arteries arising from the PCA is mandatory.
