Authors reviewed the relationship between the cerebral vasospasm in the cerebral angiograms and CT findings in the 41 cases of subarachnoid hemorrhage due to intracranial aneurysmal rupture during the period from July 1982 to February 1984. This study was based upon the CT scans performed within the first 5 days and angiograms obtained between 7 and 17 days after subarachnoid hemorrhagie. Conclusions were as following : 1) No relationship between the site of aneurysm and the amount of subarachnoid blood. 2) No relationship between the site of aneurysm and the development of vasospasm. 3) No definite additional influence of the intracerebral or intraventricular clots on the development of vasospasm. 4) High incidence of severe vasospasm with clot or thick layer in subarachnoid space.

In order to define the hospital course and the best surgical timing for the poor grade subarachnoid hemorrhage(SAH) patients, 131 patients(from 1989 to 1991) whose clinical grade on admission were Hunt and Hess grade III to V were analyzed. Their admission grades was III(90 patients), IV(30 patients), and V(11 patients). Patients were grouped into the early surgery group(within 3 days of the last hemorrhage), the intermediate group(4 to 14 days), the late surgery group(14 days after the last hemorrhage), and non-surgical group. Early surgery was performed on 17 patients, intermediate on 31 patients, and late on 54 paients. Twenty-nine patients did not undergo surgery. This non-surgical group had a high mortality rate(72.4%). During the waiting period for a delayed surgery(later than 3 days), 21% improved their clinical state, 53.5% were stationary and 25.5% became worse. Morbidity and mortality were compated among these three surgical groups and the non-surgical group, with sratistical analysis using chi square test and Fisher's exact test. No statistical differences were noted between the management groups in terms of associated disease, location of aneurysms, Fisher's grade, occurrence of hydrocephalus or symptomatic vasospasm. The mortality rate was significantly lower in the combined surgical groups than in the non-surgical group(p<0.05). Mortality was related to the timing of surgery. It was higher after early surgery than in the other two gorups, but it was not different between the intermediate and late surgery groups. Morbidity was not different among the three surgery groups. The major cause of morbidity and mortality in the early surgery group was brain swelling, while rebleeding, hydrocephalus, and vasospasm, were the main causes in the intermediate and delayed surgery groups. It is concluded that it is not recommended that early surgery must be done in all the poor grade SAH patients. However three days after the last hemorrhage, it is better to perform surgery as soon as possible, because there were no statistically significant differences between the intermediate group and the late surgery groups in the mortality and the morbidity rates.

Authors experienced 36 cases of middle cerebral artery aneurysms in 35 patients. Among 36 cases, M1 aneurysms were 4 cases, M1 bi-or trifurcation aneurysms 30 cases, and distal aneurysms 2 cases. The majority of M1 bi-or trifurcation aneurysms were operated upon by the superior temporal gyrus approach. Trans-sylvian approach was used only in M1 aneurysms, in cases of short M1, in associated anterior circulation aneurysms, and in second operation to the unruptured middle cerebral artery aneurysms. Our results were encouraging. Mortality was 5.6%, and morbidity was also 5.6%.

Pedicled bone flap raised from the volar aspect of lower end of the radius, pedicled by the pronator quadratus has been used for the treatment of scaphoid nonunion and Kienbock's disease. From July 1991 to Jan. 1992, authors performed this procedures for 3 cases of Kienbock's disease. Patients were 2 cases in the left hand, l case in the right hand. There was no critial trauma history. Age at operation were 25, 37 and 57 years. All patients were in Stage I in 2 cases and stage II-A in 1 case of Lichtman's radiologic classification. Preoperative grip powers were 11%, 38%, 63% and pinch powers were 20%, 41%, 61% of that of normal opposite hand. Follow up periods were 28, 31 and 33 months. At last follow up roentgenographic finding shows no progression of necrosis of lunate, new bone formation, decreased sclerosis, and joint space were preserved in all cases. The fuctional results at the last follow up were as follows. Pain during motion was markedly diminished in all patients. Grip power were 57%, 89% and 96% and pinch powers were 68%, 83% and 100% of that of normal opposite hand with use of calibrated Jamar dynamometer which showes significant increase than preoperative state. The ranges of motion of wrist were as follows. Volar flexion were 40, 45 and 80 degree. Dorsiflexion were 10, 20 and 45 degree. Ulnar deviation were 10, 20 and 30 degree. Radial deviation were 10, 25 and 30 degree. This viable bone graft with blood supply gives very satisfactory clinical results.

Diagnostic radiologic studies for angiosarcoma are usually non-specific, but selective angiography is notablyexceptional, and there had been a few reports of CT or US featurs of hepatic or splenic angiosarcoma. We recentlyexperienced a case of hepatic and splenic angiosarcoma demonstrated by CT, US and selective angiogram in34-year0old man.
