OBJECTIVE: Internal carotid artery (ICA) trunk aneurysms are rare constituting about 0.9 to 6.5% of all ICA aneurysms. They may arise from medial, lateral, ventral (posterior) or dorsal (anterior) walls of ICA. The most frequent site of origin is dorsomedial, followed by dorsal, dorsolateral and ventromedial wall. ICA dorsal wall aneurysms can be divided into the saccular type and blister type, which have different shapes, wall histological features and surgical tactics. The authors report an analysis of 27 cases of ICA trunk aneurysms treated with surgical clipping or GDC embolization. METHODS: Of 145 cases of ICA aneurysms from May 1998 to December 2005, we found 27 cases (17.5%) of such unusual aneurysms located at nonbranching sites of the intradural ICA. Features of neuroimagings and medical records were analyzed. RESULTS: Out of 27 aneurysms, 10 were located at ICA dorsal wall, 8 aneurysms were developed at ICA medialwall. Seven aneurysms originated from ICA ventral wall. Seven cases presented with subarachnoid hemorrhage and 20 cases were found unruptured. Two patients had blister-like aneurysm, and the others had saccular aneurysms. All patients were treated successfully with microsurgical clippings or GDC embolization. Microsurgical clipping were performed in 14 cases and among them, removal of anterior clinoid process was done in 12 cases. Eleven aneurysms were occluded with detachabel coil. Two patients underwent balloon occlusion of ICA. Blister aneurysm was clipped including a portion of the normal ICA wall. Good outcomes were obtained in 25 patients, and two patients were dead. CONCLUSION: ICA trunk aneurysms are developed at any site of ICA circumference. Therefore we consider a variety of treatment strategies. On clipping of aneurysms at proximal ICA trunk, removal of anterior clinoid process is important. Endovascular treatment may be good an alternative. However, surgical treatment is essential for blister like aneurysms.

Chylous ascites in neonates is an unusual and etiologically poor understood entity. We report a male newborn who suffered from abdominal distension and respiratory distress after birth. Paracentesis was performed and ascitic fluid was obstained. Analysis of the fluid revealed cell count (RBC 10,000/mm3, WBC 800/mm3: segmented form-72%, lymphocyte form- 28%), protein 4,100 mg/dl, glucose 57 mg/dl, cholesterol 53 mg/dl, triglyceride 28 mg/dl. Culture of ascitic fluid grew no bacteria. A plain film of abdomen and abdominal sonogram showed massive ascites. On the 4th hospital day, gastrografin enema showed microcolon and ileal atresia. On the 6th hospital day, ileocolostomy has been performed and operative findings sho- wed blind pouch in terminal ileum, massive inflammation and extensive adhesion on peritoneum. After operation, he gained weight by continuous gavage feeding. He discharged on the 36th hospital day.

High frequency jet ventilation(HFJV) induces adequate gas exchange with tidal volume smaller than that of other conventional ventilation method. In critically ill patients, HFJV reduces the unwanted hemodynamic effects of conventional ventilation caused by the increase in intrathoracic pressure. But general anesthesia with jet ventilator has been dependent only on intravenous anesthetics. Therefore, this study was done to administer inhalation anesthetics(N2O, enflurane) during HFJV. This study was carried out from June 1992 to January 1993 in the 64 operated patients who beIonged to ASA class I, II in Chung Ang University Hospital The 22 patients using conventional ventilation were control group and the other 42 patients who had inhalation anesthesia by using HFJV were experimental group. In all patients, blood pressure and heart rate were checked on preinduction, postinductive 0, 5, 10, 15, 20, and 30 minutes. The result were as follows I) Systolic blood pressure was increased just on postinduction in both groups(P<0.05). It was decreased from postinductive 5 minutes to 30 minutes in control group, but there was no change in experimental group(P<0.05). 2) Diastolic blood pressure was increaeed just on postinduction in both groups(P<0.05). But it was increased from postinductive 5 minutes to 30 minutes in experimental group(P<0.05). 3) Mean blood pressure was increased just on postinduction in both groups(P<0.05). It was increased from postinductive 5 minutes to 15 minutes in control group and from postinductive 5 minutes to 30 minutes in experimental group(P<0.05). 4) Heart rate was increased just on postinduction and postinductive 5 minutes in control groupg <0.05), and increased from postinductive 0 minute to postinductive 30 minutes in experimental group(P<0.05). 5) pH was increased on postinductive 30 minutes compared to that of preinduction in both groups(P <0.05). 6) PaCO2 was more decreased on postinductive 30 minutes than preinduction in both groups (P<0.05), but there was no clinical significance. And PaO2 was increased at postinductive 30 minutes(P<0.05), which resulted from the increase of FiO2. As above results, inhalation anesthesia with HFJV is supposed to be useful if the difficulty of controlling the concentration of inhalation anesthetics and the contamination of operating room by expelled inhalation anesthetics were solved.

The authors reviewed findings of enhanced abdominal computed tomographic (CT) scans to the difference between a higher dose of conventional ionic contrast media(iothalamate meglumine) and a lower dose of a new, nonionic contrast material (ioversol). One hundred adult patients were divided into two groups. Each group consisted of 50 patients. Iothalamate meglumine and ioversol were intravenously administered in each group. The ratio of the male to female in the former was 28.22, and the latter 29:21. We examine the degree of renal streak artifact and measure the Hounsfield number of urine in renal collecting system. There were significant differences of the degree of the streak artifact depending upon the osmolality of contrast media used and that was related with urine CT number (P value<0.005). We authors conclude that nonionic low osmolar contrast media is prone to cause streak artifacts and distortions of renal image than conventional ionic high osmolar contrast media.
