[Dissecting aneurysm of the middle cerebral artery with subarachnoid hemorrhage and brain infarction: a case report].

This report describes a surgical case of a dissecting aneurysm of the left middle cerebral artery with subarachnoid hemorrhage and ischemic insult. A 48-year-old man with pure motor aphasia was referred to our hospital. CT scans demonstrated subarachnoid hemorrhage in the left frontal region. CT scans on the next day showed a small brain infarction in the left precentral artery and central artery territories. The first left carotid angiograms showed stenosis at the M2 portion of the middle cerebral artery. On the 16th day, the second left carotid angiograms revealed a pearl and string sign. We diagnosed a dissecting aneurysm of the middle cerebral artery. The dissecting aneurysm was wrapped using the pterional approach and STA-MCA anastomosis was also performed. The postoperative course was uneventful and the motor aphasia improved.

Thyroplasty type I with ceramic shim.

To improve hoarseness or misswallowing caused by unilateral recurrent laryngeal nerve paralysis, medialization of paralyzed vocal cord has frequently been performed. This method includes such techniques as injection method, insertion method, and arytenoid adduction, each presenting its merits and demerits. The insertion method which can be done while monitoring the patient's voice seems advantageous in that the technique is easy to perform and generally guarantees the voice improvement. Among insertion methods, Isshiki thyroplasty type I is the one most representative as well as popularized. However, since a silicone shim is inserted in this operation, it may be accompanied by the risks of carcinogenicity, foreign body reaction, and induction of collagen disease of silicone. Therefore we planned to use a ceramic as a safe substitute instead of silicone. There has been no article reporting the use of ceramic in this type of surgery. We used a fibrin glue to fix the ceramic shim and for hemostasis, which was found very useful. Hitherto, 2 cases of unilateral recurrent laryngeal nerve paralysis underwent Isshiki thyroplasty type I using ceramic shim with satisfactory results.
