Evlauation of pulmonary vascular changes and pre-and postoperative hemodynamic findings were performed in 25 patients who had ventricular septal defect associated with sevese pulmonary hypertension. Lung biopsy were done preoperatively in two patients and during operation in twenty three patients. Also the postoperative systemic and polmonary arterial pressure were obtained about 10-20 minutes after the cardiopulmonary bypass. The results were as follow: 1) There was no relationship between the severity of pulmonary vascular changes(Health-Edwards classification) and the patients age(X2=4.4427, P=0.2175). 2) There was a good correlation between preoperative ratio of pulmonary to systemic vascular resistance(Rp/Rs) and ratio of pre-and postoperative pulmonary to systemic arterial pressure(r=0.4846, P<0.05). 3) There was a significant correlation between the degree of medial wall thickness and preoperative Rp/Rs(r=0.6535, P<0.005). 4) There was no correlation between perioperative hemodynamic findings and medial wall thickness in the patients aged below 2 years.

This study was performed to evaluate the clinical significance of SCC as a tumor marker in patient with squamous cell carcinoma of the cervix. We measured the serum levels of SCC by radioimmunoassay in patient with invasive squamous cell carcinoma of cervix to determine the prognostic value, correlation with the presence of lymph node metastasis, response to treatment, and those value in the early detection of recurrence after treatment. The result was: 1) In 117 of 174 patients with cervical cancer, the pretreatment positive rate of SCC was 47.0%(57/117). In each stage, the stage Ia was 25.0%, Ib 26.3%, IIa 56.0%, 62.6%, III 57.1%, IV 100%, and the recurrent case was 37.5%. 2) In 79 of 174 patients with cervical cancer, the pretreatment positive rate of SCC was 44,0%(30/69) in no evidence of malignancy patients, but 60.0%(6/10) in recurrent or permanent patients(p>0.05), 3) In 133 of 174 patients with cervical cancer, the posttreatment positive rate of SCC was 2.6%(3/117) in no evidence of malignancy patients, but 50.0%(8/16) in recurrent or permanent patients(p<0.05). 4) In 48 patients of 174 with cervical cancer who underwent radical hystrectomy, the positive rate of SCC was 71.4%(5/7) in pelvic lymph node positive patients but 19,5%(8/41) in pelvic lymph node negative patients(p<0.05). We concluded that the pretreatment SCC level was not effective as a prognostic value, but well correlated with pelvic lymph node metastasis, and serial measurements of serum levels of SCC provided a reliable clue for early detection of recurrence or progression of disease, so it may be useful for monitoring cervical carcinoma patient.

The MR images of 13 patients with brain abscesses were retrospectively reviewed. The abscesses were solitary in 11 patients and multiple in 2 patients. They were located in the corticomedullary junction of the cerebral hemispheres(11) and cerebellum (2).: The sizes of the abscesses were variable, ranging from 1 cm to 5 cm in diameter. They were round (5), oblong (4) or multilobulated (4) in shape. Massive surrounding edema was found in 12 patients. The signal intensity of the abscess contents was hypointense to gray matter and hyperintense to CSF on T1-weighted images, and hyperintense to gray matter on both proton-density-and T2-weighted images. In 5 patients the abscess contents were heterogeneous on both T1-and T2-weighted images. The signal intensity of the abscess walls was isointense(11), slightly hyperintense (1) or hypointense (1) relative to gray matter on T1-weighted images, whereas they were isointense (4) or hypointense (9) on T2-weighted images. Of 10 patients with Gd-enhanced-T1-weighted images, 5 patients(50%) showed thin, smooth, rim enhancement, while the other 5 patients revealed somewhat irregular thick wall enhancement Satellite or daughter abscesses were found in 6 patients. Meningeal or ventricular wall enhancement suggesting meningitis or ventriculitis was associated in 3 and 1 patient, respectively. In conclusion, the characteristic morphology and intensity of the abscess capsule, massive surrounding edema, satellite abscess and associated meningitis or ventriculitis are characteristics of the brain abscess, even though they are not entirely specific to allow for accurate diagnosis in all patients.

In the past 5 years, the authors have performed microsurgical reconstruction of the lower leg in 37 patients. Among them, modified microsurgical salvage procedures were performed in 11(29.7) cases with vascular compromise, suggested by the preoperative angiogram of the affected lower leg demonstrating no visible, or only one visible major arter. Modified salvage procedures included free flap operations using distally-based arterial inflow(n=2), temporary diversion of the single main artery with secondary vein grafting(n=2), Jungcross-leg fashioned free flaps(n=4), and end-to-side anastomosis of the main artery((n=1). In absence of arterial flow after lower leg trauma, as interpositional vein graft(n=2) was performed to restore blood flow. No vascular problems occurred after the free flap transfer. However, 9 patients experienced different degrees of limping gait, ranging from as mild(n=2), moderate(n=6) to severe(n=1) at the mean follow-up period of 18 months. In reconstruction of a vascular compromised lower leg, modified salvage procedures should be reviewed and selected after exploration of all vessels, both proximal and distal to the zone of the injury. When evaluating what method is the most appropriate, socioeconomic efficiency and patients' individual requirments should be considered.

An axial-pattern flap can be transferred as the free-flap and has many merits over a random-pattern local flap. However, this has limitations of available vascular architecture and donor site. To overcome these problems, many types of prefabricated flaps have been designed using vascular bundles. It is possible to convert a random-pattern flap to a neovascularized axial-pattern flap by transferring a vascular pedicle. In an attempt to study the effects of prefabrication using vascular bundles, the survival rate between random-pattern flap and prefabricated axial-pattern flap was compared in this study. The rabbits were divided into two groups. The control group was consisted of the random-pattern flap and the prefabricated group was consisted of the prefabricated axial-pattern flap using femoral vascular pericles of rabbits. Femoral vascular pedicles were transferred under the 5x5cm lower abdominal flaps without any perivascular tissue. Three weeks later, random-pattern flaps were elevated without any axial vascular pedicle and prefabricated flaps were elevated based on the transferred femoral vascular pericles. The survival rate of the flaps in the control group and experimental group was 67.37% and 98.87% respectively. Based on the result of t-test there was significant difference between two groups. According to these results, it is concluded that prefabricated flap using transferred vascular pedicle was more effective than random-pattern flap. We think that this technique is versatile for wound repair and for use in other aspects of plastic and reconstructive surgery.
