BACKGROUND: Transradial coronary intervention was introduced recently. It has less bleeding and vascular complications and advantage of early ambulation. METHODS: We compared 142 transradial coronary interventions (101 stents, 56 balloon angioplasty and 18 rotablation) with 120 transfemoral interventions in 230 patients from January to August 1998. RESULTS: Overall success rate was not different between two approaches (92% vs 89%), but smaller sized sheath and less amount of contrast agent were required in transradial interventions compared to transfemoral interventions. Conventional guiding catheters which are used in transfemoral approach were used in most cases (94%) of transradial interventions. Judkins left 3.5 (in stead of JL4.0 in femoral approach) and Judkins right 4.0 were the most frequently used guiding catheters in transradial approach. Stent implantation was successfully done in 99 out of 101 lesions (98%) in transradial intervention and 76 out of 78 lesions (97%) in transfemoral intervention. Rotational atherectomy and primary balloon angioplasty or stenting were done successfully in 10 - 20% of the patients in both groups. All procedures were done successfully without any major procedure-related complications (myocardial infarction, death, bypass surgery) or major vascular complications in both groups. During the clinical follow-up of transradial group, punctured arteries showed 10% incidence of radial artery pulse weakness with 3% of pulse loss. CONCLUSION: Transradial approach is useful another feasible route for coronary interventions. The feasibility of primary balloon angioplasty or stenting and rotational atherectomy by transradial approach should be evaluated in the future.

BACKGROUND: Carotid artery stenosis is not infrequently associated with coronary artery disease. However, the technique performing selective carotid angiography is not established during right transradial coronary angiography. We investigated the reliability and safety of selective carotid angiography from the right transradial approach. MATERIALS AND METHODS: Following right transradial coronary angiography, selective carotid angio-graphy was performed using a 5 Fr Simmons-2 catheter in 103 patients (59+/-8 years [range, 18-80], 78 males). Ninety five (92%) patients had significant coronary artery disease. Subclavian and innominate arteries were moderately tortuous in 25 (24%) patients and aortic arch was elongated, more vertically oriented in 20 (19%). After forming a loop in ascending (n=65, 63%) or descending (n=38, 37%) aorta, the catheter was withdrawn and rotated counterclockwise to engage its tip in left carotid artery and innominate artery subsequently. After the catheter tip was adjusted at each ostia of carotid arteries, contrast material was delivered. In 63 (61%) patients, the procedures were performed on outpatient basis. RESULTS: Bilateral selective carotid angiography was successfully performed in 101 (98%) patients. In two patients with severely tortuous subclavian artery, the catheter was not engaged selectively in left carotid artery. The image quality of the angiograms performed by manual injection was determined satisfactory. Significant carotid stenosis was found in 17 (17%) patients. There were no complications, including thromboembolism and arterial dissection. CONCLUSION: Selective carotid angiography can be performed reliably and safely using a 5 Fr Simmons catheter from the right transradial approach. This technique is useful for evaluation of isolated or associated carotid artery stenosis from the right transradial approach.

The mullerian ducts join the sinovaginal bulb at a point known as the mullerian tubercle. Canalization of the mullerian tubercle and sinovaginal bulb is necessary to give a normal vaginal lumen. If the area of junction between these structures is not completely canalized, a transverse vaginal septum will occur. This may be partial or complete and generally lies at the junction of the upper third and lower two thirds of the vagina. It occurs in about 1 per 75,000 females. Partial transverse vaginal septa have been reported in diethylstilbestrol (DES)-exposed females. In the prepubertal state, diagnosis is generally not made unless there is the development of a mucocolpos or mucometrium behind the septum. At puberty, however, if the septum is complete, hematocolpos and hematometrium may occur in a fashion similar to that seen in the imperforate hymen, except that there is no bulging at the introitus. The patient with an incomplete transverse septum may bleed somewhat but will still develop hematocolpos and hematometrium over time and may also complain of foul smelling vaginal discharge.

PURPOSE: The aim of this study was to analyze various clinical characteristics of ischemic colitis according to its location. METHODS: The medical records of 92 cases of gastrointestinal ischemic colitis (IC) diagnosed at Bundang CHA Hospital from 1995 to 2008 were reviewed and analyzed retrospectively. The patients were diagnosed by using colonoscopic biopsies or laparotomy findings. The patients were divided into two groups, right and left, according to the main involvement area of the IC at the embryologic boundary line of the distal transverse colon, and the two groups were compared as to clinical characteristics and co-morbid diseases. RESULTS: Left IC was present in 59 patients (64.1%) and right IC in 33 patients (35.9%). No differences between the two groups in terms of clinical characteristics, cardiovascular disease and diabetes mellitus were observed. However, in 16 cases with renal failure, 10 patient had right IC and 6 patients had left IC, and this difference had statistical significance (P = 0.014). Among the 16, the 11 patients requiring hemodialysis included 8 with right IC (24.2%) and 3 with left IC (5.1%; P = 0.009). Among the 19 cases of severe IC requiring surgical treatment or involving mortality, irrespective of surgery, 11 patients showed right IC and 8 patients showed left IC (P = 0.024). CONCLUSION: Right-side ischemic colitis was significantly associated with renal failure and disease severity, so patients with right-side colon ischemia should be more carefully observed and managed.

Varicocele is the most frequent cause of male subfertility. Because it is the most common surgically correctable cause of male infertility, its diagnosis is important. For diagnosis of varicoceles, venography, thermography, and doppler stethoscope were available, but they involved invasiveness, inaccuracy, lack of objectivity and cosiliness. Two noninvasive methods for detecting varicoceles. scrotogram using Technetium and digital infrared thermography imaging(DITI), were evaluated in 52 patients complaining of infertility. The results of scrotogram and thermography were not consistent in these patients. When the varicoceles were confirmed with internal spermatic venography or high ligation of internal spermatic vein, the physical examination was the most accurate method. compared with scrotogram and thermography. Scrotogram (0.73) was more sensitive than thermography(0.64). The each combination of the two of physical examination scrotogram and thermography increased the accuracy in terms of sensitivity and positive predictive value. This study suggest that the combination of scrotogram and thermography with physical examination would increase the diagnostic accuracy in the varicoceles.

Since Memmalaar first reported the use of bladder mucosa graft technique in penoscrotal hypospadias in 1947, this technique has been used with reasonable success for the reconstruction of new urethra for the posterior hypospadias and hypospadias cripples. The a bladder mucosa is abundantly available, sterile and has good elasticity. This mucosa does not produce hair, does not excoriate, and does not desquamate from the exposure of the urin. Two new urethrae in patients with posterior hypospadias, aged 11 and 21, were successfully reconstructed with bladder mucosal graft technique. A minor meatal stricture developed in one patient. However, the over-all results of this technique appear to be satisfactory.
