Background Adenomyosis, a benign gynecological disease, causes cerebral infarction. Similar to Trousseau’s syndrome, it elevates cancer antigen 125 (CA125) and D-dimer levels; causes hypercoagulability; and results in cerebral infarction. However, no case of adenomyosis causing major cerebral artery occlusion and requiring endovascular thrombectomy has yet been reported. We report on a woman with middle cerebral artery occlusion caused by adenomyosis progression with a benign gynecological tumor and recurrent cerebral infarction. She was successfully treated by endovascular thrombectomy and hysterectomy. Case presentation A 48-year-old woman with heavy uterine bleeding was transported by ambulance to our hospital. Upon arrival, she presented with impaired consciousness. Laboratory test results revealed decreased hemoglobin (8.2 g/dL) and elevated D-dimer (79.3 µg/mL) levels. Radiological imaging revealed adenomyosis, a left ovarian tumor, multiple uterine myomas, and old and new bilateral renal infarctions. She experienced repeated episodes of excessive menstruation caused by adenomyosis and was scheduled for hysterectomy in 2 months at another hospital. After hospital admission, uterine bleeding stopped. However, 5 days after initial bleeding, she had another episode of heavy uterine bleeding and developed left hemiparesis and dysarthria 20 min later. Brain magnetic resonance imaging revealed bilateral multiple cerebral infarctions indicating right middle cerebral artery occlusion. Thus, endovascular thrombectomy was performed, and anticoagulant therapy was administered. Laboratory test results after thrombectomy revealed elevated CA125 (3536 U/mL) and CA19-9 (892 U/mL) levels. She was at a risk of recurrent heavy uterine bleeding leading to repeated cerebral infarction because of anticoagulant treatment. Therefore, we performed hysterectomy and ovariectomy 11 days after initial bleeding. Histopathological assessment revealed no malignancy. Although she developed asymptomatic pulmonary thromboembolism 14 days after initial bleeding, D-dimer and tumor marker levels returned to normal soon after gynecological surgery. At 15 months post-surgery, she had not experienced further ischemic events. Conclusions Adenomyosis with benign gynecological tumors may be associated with elevated D-dimer and tumor marker levels; excessive menstruation; and anemia. It may cause systemic thromboembolism, including cerebral infarction. To our knowledge, no other study has reported that adenomyosis causes major cerebral artery occlusion requiring endovascular thrombectomy. Hysterectomy may be an effective radical treatment of this condition.
Background: Recurrent cerebral infarction caused by traumatic extracranial vertebral artery dissection (EVAD) is treated medically and surgically. We report a case of EVAD that was treated using surgical clip occlusion of the V3 segment to prevent recurrent cerebral infarction. Case Description: A 48-year-old man was admitted for a cerebral infarction caused by EVAD and was treated using 200 mg/day cilostazol. Afterward, the cerebral infarction recurred. Digital subtraction angiography revealed that initial severe stenosis of the VA ostium resulted in the final occlusion and that collateral vessels to the VA remained. We continued antiplatelet therapy, but the cerebral infarction recurred due to thromboembolism of the collateral vessels. Parent artery occlusion was planned. We exposed the V3 segment of the VA and clipped it to prevent the recurrence of cerebral infarction. Conclusion: Surgical clip occlusion of the V3 segment was effective for treating recurrent cerebral infarction caused by traumatic EVAD that had remained an issue despite continuing medical therapy.
