The fashion of vascular anastomosis, end-to-end or end-to-side (E-to-S), are depended upon surgeon's preference or surgical situations. In E-to-S anastomosis two different methods of arteriotomy are applicable but it has been suggested the type, either elliptical or slit arteriotomy, play a different role in the flow hemodynamics. We thought that the difference is more considerable in microvascular surgery. This study examines the effects of elliptical versus slit arteriotomy on morphologic vessel patency. Twenty male Sprague-Dawley rats were divided into two groups of ten rats each. Both carotid arteries were selected as a experimental model. During the procedures the rat brain was tolerable to ischemia and all animals were survived after operations. The morphologic analysis of anastomosis site was through resin-casting method with scanning electromicroscopic examination. The results showed notable difference between two groups in three-dimensional morphology at two-month of operation. This difference may affect the flow hemodynamics and long-term vessel patency. In microvascular anastomosis, the mortpologic difference of the elliptical arteriotomy is worse than slit arteriotomy which compromises the vessel circumference.

Rhabdomyosarcoma is the most frequent cancer involving the trigone of the bladder, the proximal urethra, vagina and paratesticular tissue in children, and 15 percent of rhabdomyosarcoma in children arise in the urogenital tract. Rhabdomyosarcoma is highly malignant neoplasm with a tendency toward early infiltration of adjacent structures and metastases to regional lymphnodes and distant organs. We report tow cases of paratesticular rhabdomyosarcoma with brief review of literatures.

PURPOSE: Authors reviewed CT and MR findings of patients with parapharyngeal masses, and their incidence and characteristic findings were studied. MATERIALS AND METHODS: We reviewed 27 CT and 9 MR of pathologically proven 29 patients with primary parapharyngeal mass Neurogenic tumor (17 cases) and other rare masses (3 carotid body tumors, 2 pleomorphic adenomas, 2 cavernous hemangiomas, 1 cavernous lymphangioma, 2 carotid artery pseudoaneurysms, 1 non-Hodgkin's lymphoma, 1 idiopathic cervical fibrosis) were included and the characteristic CT and MR findings were studied. RESULTS: Neurilemmoma was seen as a well-demarcated, solid mass of heterogeneous attenuation or intensity, so that pleomorphic adenoma of minor salivary gland origin could not be differentiated by demarcation, attenuation, or signal intensity of the tumor itself. The direction of carotid artery displacement was not constant in cases of neurilemmomas while the styloid process was constantly displaced laterally in all cases. Characteristic CT and MR findings of other rare tumors were described. CONCLUSION: Neurogenic tumor is the most common parapharyngeal space mass and the direction of displacement of styloid process might be helpful in differential diagnosis from pleomorphic adenoma. Other rare tumors showed very characteristic CT and MR finidings and could be differentiated easily.

Extravasation necrosis due to intravenously administered fluids and drugs is an increasing problem in hospital practice. The incidence of extravasation is variable but skin necrosis is a potentially devastating complication of intravenous therapy. Local injection of hyaluronidase has been recommended for several types of infusion extravasations. The previous studies found hyaluronidase to be effective in the prevention of necrosis following intradermal nafcillin, 12% dextrose, sodium bicarbonate, aminophylline or vince alkaloids.The objectives of the study are to determine the dosage of hyaluronidase which is effective in reducing extravasation necrosis caused by 10% calcium-gluconate and to establish how soon after this extravasation it must be given to retain its effectiveness.Study I evaluated control versus only normal saline group and normal saline with hyaluronidase groups (dose:75,150,300,450 units; all in volume 2 ml, treatment delay:immediate, 15-minutes delay, half hour delay, one hour delay, three hour delay). Size and rate of eschar were compared between groups. Study II was undertaken to examine the evolution of calcium-gluconate induced soft tissue injury in the rabbit. The histologic findings of extravasation sites were compared between groups. A statistically significant protective effect was found in the treated group versus the nontreated group within 15 minutes to 30 minutes. The most effective protection was achieved by the immediate injection of 300 units dosage of hyaluronidase.In conclusion, in the 10% calcium gluconate-induced extravasation, the given data suggest that one can expect the most protective effect with a 300 units dosage of hyaluronidase and within half-hour delay in the treatment group.

This study is comprehend the reality and characteristics of C.V.A. patients and to be helpful to its prevention and cure by resarching C.V.A. outpatient or inpatients who visited some of the oriental hospitals during three months from April 1 to June 30 1996 which are located in Taegu and Kungbuk Province, and concluded as follow: 1. The general characteristics of the subjects were: (1) 52.3% of the subjects were male. (2) In terms of age, 34.7% of them were in the sixties. (3) In terms of job, 28.5% of them were housewives(the highest percentage). (4) 77.6% of them had their spouses. (5) 67.2% of them were middle class. (6) In terms of educational background, 24.6% of them were literate of korean alphabets, and 23.4% were elemantary school gradurates. (7) 51.6% of them were outpatients. 2. 73.3% of the subjects experienced C.V.A. for the first time, and 23.1% were at recurrence, and 3.6% were chronic. 3. In terms of C.V.A. types, 49.8% of the subjects had cerebral hemorrhage, and 41.9% had cerebral infarction, and 8.3% had the others. In cerebral hemorrage, the percentage in "male, forties, job of sales service, unmarried, middle class, high educational background" were higher than the others respectively. And in cerebral infarction, the percentages in female, over seventies, official job, married, upper class were higher than the others respectively. 4. In terms of reasons of C.V.A. 49.5% of them were high blood pressure, and 24.2% were high stress, and 18.8% were overwork, and 4.0% were fatness, and 2.5% were heredity.

The level of satisfaction with C.V.A. patient-healing methods ; In medical therapy, 43.3% of C.V.A. patients thought it "usual", and 44.1% thought it "satisfactory" and 7.9% thought it "unsatis-factory". In acupunture and moxibustion 39.7% of the C.V.A. patients thought it "usual", and 53.0% thought it satisfactory" and 3.3% thought it "unsatisfactory". The level of satisfaction With Physiotherapy was average 61.7% and 4.0% was "unsatisfactory". From above statement, by considering those characteristics we should develop programs and materials to be health to the prevention and cure of C.V.A. and we should help hospitals and medical personnel families concerned to make use of them.
