The suture materials influence the success of microvascular anastomosis importantly. The purpose of this experiment is to observe the effect of absorbable suture material and nonabsorbable suture material in microvascular anastomosis. The study was carried out on one side of carotid arteries of fourty rats which were anesthetized intraperitoneally with urethane. The experimental procedures differed in two groups, Group A in which the carotid artery was sutured with 10-0 monofilament polyglycolic acid, Group B in which the carotid artery was sutured with 10-0 monofilament nylon. Gross and histological examination were used to compare the results of end to end suture above two suture material. The results were as follows. 1. Nylon had greater tensile strength and ease of handling than polyglycolic acid, but held knots poorly. 2. Polyglycolic acid had difficult handling and lesser tenslie strength than nylon, but held knots hardly. 3. Polyglycolic acid had high patency rate, some lesser tissue response than nylon.

We tried extracapsular cataract extraction and PCL implantation with Ocutome-FragmatomeII System and Disposable Two-Way Needle. 160 eyes were operated with this method, 101 eyes were followed up over 2 months period. Clinical results were not significantly different from previous reports of ECCE and PCL implantaion. Corrected visual acuity 0.5 or better after 2 months of surgery were 95%. No serious intra-operative and post-operative complications were noted. We suggest Ocutome-FragmatomeII System and Disposble Two-Way Needle could be used for ECCE and PCL implantation in case of absence of I and A system.

In view of the problems with infection, traditional orthopedic teaching has held that the use of metalic fixation in open fractures is contraindicated. But the bone shortening and internal fixation of amputated limb is a principle for replantation. The authors experienced 23 patients of replanted limbs including femur, tibia, humerus, radius and ulnar among total 142 replantations and also analysed them in the respect of the relationship among soft tissue injury, fixatives, bone union and infection rate from February, 1975 to July, 1981 in this department. The rate of delayed union, nonunion and infection were 22.6%, 6.5% and 25.8% respectively. It seems that the union process of bone in replanted limbs is similar to that of the open fracture and also rigid internal fixation is the most useful for bony union.

Eleventh heel pad reconstruction with neurovascularized dorsalis pedis free flap or rotation flap have performed during recent three years in department of Orthopedic Surgery, Kyung Hee University Hospital. Neurovascularized dorsalis pedis free flaps were seven and neurovascularized dorsalis pedis rotation flaps were four. All patients had complained of painful limping and ulceration in grafted heel. In 5 months to 34 months follow up study, the following results were obtained. The success rate of dorsalis pedis flap was 100% except one partial peripheral necrosis. The weight bearing function and tactile protective sensation on reconstructed heel pads were excellent. Neurovascularized dorsalis pedis free flap or rotation flap is recommended to satisfactory methods in heel pad reconstruction. Neurovascularized dorsalis pedis rotation flap easier and safer technique than neurovascularized dorsalis free flap.

We presented two cases of entrapment neuropathy which were confused with herniated lumbar disc syndrome. One was "meralgia paresthetica in association with lumbar disc herniation", and "the other inguinal neuritis along with obturator neuritis". Syndromes of these entrapment neuropathies were confirmed by subcidence of pain and creation of progressively longer pain-free intervals after analgesic blocks of the corresponding nerves by infiltration of Xylocaine and prednisolone.

Although there are differences in the mode of onset, symptomatology and clinical course in the various types of cerebrovascular lesions, the general picture may be quite similar and it is often difficult to determine the nature of the lesion in any individual case from the clinical data. In the vast majority of cases the symptoms of a cerebrovascular accident are of sudden onset and reach maximum intensity within few minutes or a few hours at the most. Locksley, et al. have reported autopsies on people who died from spontaneous intracerebral or subarachnoid hemorrhage, and they found that a primary or metastatic brain tumor was the cause of hemorrhage in only 2%~3% of their necropsy. We presented our experience with two such patient whose clinical pictures before the surgery were quite similar with those of cerebrovascular accident. Cases with a large chronic subdural hematoma and cerebral glioblastoma multiforme demonstrated a sudden and dramatic onset of coma and focal neurological symptoms immediately before admission to the hospital. The responsible mechanism or etiology for the mode of such sudden dramatic onset of symptoms may be derangement of intracranial pressure mechanism and sudden hemorrhage in the tumor.

A case is presented in which left-sided hemiparesis was caused by a fibromuscular dysplasia of the right internal carotid artery in the neck, and it used as a basis for discussion of the angiographic features. The 24-year-old woman was admitted to our Department of Neurosurgery, Korea University hospital, with the complaints of headache and left-sided hemiparesis which developed abruptly about one month before this admission. The carotid angiography was performed by puncture of the right common carotid artery under the clinical impression of cerebral thrombosis, which showed no gross intracranial abnormalities. But the characteristic findings were observed under and widening of the arterial lumen which are so-called loose stocking appearance or 'string of beads' appearance and are the typical feature of fibromuscular dysplasia. No surgical interventions such as arterial reconstruction and grafting, or arterial dilatation with bougies were applied on the patient, and she was discharged from the hospital three days after the admission. Fibromuscular dysplasia is a rare sclerotic, noninflammatory lesion of unknown etiology involving the wall of large arteries. This disease is found most frequently in early adult life and women are afflicted more often than men, This condition has been described most often in the renal arteries, where it has been found to be a cause of hypertension. Among the involvement of carotid system, the cervical portion of the internal carotid artery is most often affected, and the involvements are often bilateral. When localized to the internal carotid arteries, it can give symptoms of intermittent or permanent cerebral ischemia, but is usually asymptomatic. The typical angiographic appearance is the main parameter for diagnosis of fibromuscular dysplasia.

We present the methods of analysis of left ventricular wall motion by 2-dimensional echocardiography using computerized system. Quantiative analysis of left ventricular wall motion abnormalities depents on the used reference method, because the heart shifts and rotates within thorax during the cardiac cycle. To access left ventricular wall motion abnormalities, we studied 60 subjects(normal; 30 subjects, abnormal; 30 subjects)with 5 different floating reference methods correcting for traslation and/or rotation in two echocardiographic views. (apical 4-chamber view and apical 2-chamber view) In the first the endocardial tracings of enddiastole and endsystole in 30 normal subjects were stored in VAX-11-780 main computer and the data of these 30 normal subjects were plotted to obtain a 95% confidence interval for measured normal fractional change every five degree according to 5 reference methods. In the second, 30 patients with abnormal left ventricular wall motion analyzed and the results were compared with a 95% confidence interval. We assessed that left ventricular wall motion by visual and computerized quantitative anlysis were in close relationship according to optimal reference method. We suggested that computerized quantitative analysis of left ventricular wall motion by 2-dimensional echocardiography was clinically useful method and translation of the midpoint of mitral anulus with rotation according to center of mass was the most specific and sensitive new method of evaluating left ventricular wall motion abnormalities.
