PURPOSE: Treatment of ovarian metastasis from colorectal cancer has been controversial, and only limited data on ovarian metastasis have been reported. We reviewed the clinical features of patients with ovarian metastasis from a colorectal carcinoma. METHODS: From 1993 to 2002, 568 women were treated for colorectal cancer. Of those, 17 cases were diagnosed as ovarian metastasis. We reviewed the 17 cases retrospectively. RESULTS: The incidence of ovarian metastasis was 3.0% (17/568). The number of cases involving synchronous ovarian metastasis was 7 (1.2%). Those 7 patients also had another metastasis including ovarian metastasis. Ten cases (1.8%) involved metachronous ovarian metastasis. Of those 10 patients, 8 had ovarian metastasis in combination with other organ metastasis. The median disease-free interval from the diagnosis of the primary colorectal cancer to the diagnosis of ovarian metastasis was 9.8 months, and the median survival after the diagnosis of ovarian metastasis was 17.2 months. The median survival after the diagnosis of ovarian metastasis was 23.4 months in the ovarian- metastasis-only group, compared with 10.1 months in the group with ovarian and other metastasis. The difference in survival between the two groups was statistically significant. CONCLUSIONS: The incidence of ovarian metastasis from colorectal cancer was low. When such an event occurred, it was frequently associated with widespread disease and resulted in a poor prognosis. However, patients having only ovarian metastasis had a higher survival rate.

Amiodarone is a potent antiarrhythmic agent that is used to treat ventricular arrhythmias and atrial fibrillation. But it has a wide range of adverse effects, including pulmonary toxicity, thyroid dysfunction, liver toxicity, gastrointestinal events, corneal deposits, peripheral neuropathy and so on. Patients treated with amiodarone should be followed regularly to assess ongoing need for amiodarone, efficacy of the drug, appropriateness of dosage, adverse effects, and potential drug interactions. We experienced a case of severe weight loss due to amiodarone-induced multiple toxicity after a long course of a low dose therapy. So we report this unusual case with literature review.

PURPOSE: The aim of this study was to introduce the phenomenon that stenosis or occlusion occurs less frequently in the innominate artery than in the right subclavian and common carotid arteries, which are not first-order branches of the aorta, in Takayasu arteritis (TA). MATERIALS AND METHODS: We retrospectively reviewed the medical records and image findings of all patients who were diagnosed with TA from 2006 to 2014. Two vascular surgeons and two radiologists interpreted the images by disease character, location, and extent of occlusion based on computed tomography angiography, magnetic resonance angiography, or digital subtraction arteriography. We have also reviewed the literature on arterial involvement in TA. RESULTS: A total of 42 patients were diagnosed with TA. The mean age was 43.9 years, and 83.3% (35/42) of the patients were women. The left subclavian artery was the most common stenosis or occlusion site (17, 40.5%) among the aortic branches. The innominate artery was a less common site (3, 7.1%) than the right subclavian artery (4, 9.5%) and the right common carotid artery (9, 21.4%). All innominate artery cases were found after endovascular procedures of the right subclavian or common carotid arteries. CONCLUSION: The innominate artery might develop stenosis or occlusion less frequently than the right subclavian and common carotid arteries in Korean TA patients.

PURPOSE: The purpose of this study is to review the roll changes of surgical treatment for peripheral artery disease in endovascular era. METHODS: One hundred and twelve surgically treated cases of peripheral artery disease at a single institution during the period from 2006 to 2011 were studied retrospectively. The cases were divided into two groups of different time periods, one before 2009 (surgical period group) and the other from 2009 onward (endovascular period group). We analyzed the type and location of surgery as well as clinical characteristics of patients and treatment results. RESULTS: Fifty-three cases were for the surgical period group and 59 cases for the endovascular group. No difference in the demographic characteristics and the distribution of major atherosclerosis risk factors was found between the two groups. Additionally, the technical and functional success rate was similar in both groups. However, it is found that there were more acute cases in the endovascular period group than in the surgical period group. The number of cases in need of suprainguinal or below knee exposure was similar in both groups. In hybrid cases, suprainguinal or below knee exposures were more frequently needed during the former period than the latter period. CONCLUSION: The role of surgical treatment is currently in the process of changing. Surgical treatment seems to be a complementary alternative to endovascular treatment for chronic limb ischemia. However, it still seems to play a major role for acute limb ischemia.

BACKGROUND AND OBJECTIVES: The most important complications of the transradial coronary approach during coronary artery angiography are occlusion of the radial artery and arterial spasm which are known to be influenced by catheter size, procedure time, and repeat procedures. The purpose of this study was to evaluate the usefulness of a Tiger catheter (TC) which was designed for the selection of right and left coronary artery ostia simultaneously, compared with the Judgkins catheter (JC) during transradial coronary angiography (CAG). SUBJECTS AND METHODS: One hundred forty-four patients were randomized between groups who underwent CAG with a standard 5F JC or a TC. The procedure time and vasospasm of the radial artery, which were expressed as stenosis of the vessel diameter, were examined using a transradial approach. Four parts of the blood vessel diameter were measured at baseline, during injection of the vasodilator, and at the end of the procedure. RESULTS: There were no significant differences in gender, age, weight, or other cardiovascular risk factors between the two groups of patients. CAG was successfully performed using a TC in 89% of the patients. A TC was associated with a significantly shorter total procedure time than the JC for diagnostic CAG (451+/-120.4 vs. 542.3+/-180.5 sec, p=0.001), respectively. There was no significant difference in stenosis between the two groups (36% vs. 41% in TC and JC, respectively, p=0.358). There were no angiographic or clinical complications in each group. CONCLUSION: This study showed that the TC is associated with decreased total CAG procedure time compared with the JC.

PURPOSE: This study aims to access the usefulness of indirect computed tomographic venography (CTV) after performing computed tomographic pulmonary angiography (CTPA) to detect deep venous thrombosis. METHODS: Eighty six patients who were diagnosed with deep venous thrombosis (DVT) were retrospectively enrolled in this study. All the patients had CTPA & CTV performed within 24 hours after Doppler ultrasound (US). The CTV was compared with Doppler US for their ability to diagnose DVT. Pulmonary embolism (PE) and other findings that were detected by CTPA & CTV were analyzed. RESULTS: Among 86 patients, 83 had thrombi detected by Doppler US. CTV did not detect DVT in 11 of the 83 patients. Among the 11 patients, 8 had below the knee thrombosis, which was not in the scan area of CTV. In 2 patients, their Doppler US results could not be guaranteed. One case was a false positive result on Doppler US. The results for determining the thrombi level between Doppler US and CTV were roughly concordant. In addition to DVT or PE, 32 new lesions in 27 patients were incidentally detected by CTPA & CTV. CONCLUSION: Compared with Doppler US, CTPA & CTV are not inferior to detect DVT of the lower extremities and these modalities can also provide information about incidental disease, as well as pulmonary embolism.

Congenital tracheal stenosis can be a life-threatening disease, especially in cases involving the long-segment of the trachea. When patients are symptomatic immediately after birth or develop an accompanying complex cardiac anomaly, surgical repair can be a considerable challenge. We experienced a tracheoplasty in one early infant weighing 2.6 kg and one neonate who had ventilator dependency from long-segment congenital tracheal stenosis and congenital cardiac anomaly. One early infant, who had diffuse stenosis of distal trachea after ventricular septal defect closure, underwent resection and extended end to end anastomosis. One neonate who had diffuse stenosis of proximal trachea with tetralogy of Fallot (TOF), underwent slide tracheoplasty with total correction for TOF. Postoperative chest computed tomography showed widely patent trachea. Both infants are now well without symptoms.

PURPOSE: The aim of this study is to evaluate how much influence iliac vein compression exerts on the clinical feature of deep venous thrombosis (DVT). METHODS: One hundred five cases of lower extremity DVT were enrolled. The cases were grouped by location of the thrombus, left/right and inferior vena cava, iliac vein (IV), femoral vein (FV), popliteal vein, and calf vein. The estimated frequency was calculated by means of that the numbers of each goup were divided by the group's mean of DVT risk score. The minor distance from the right iliac artery to the fifth lumbar vertebral body overlying the left iliac vein was measured in computed tomography. Correlation of the severity and the minor distance was evaluated. RESULTS: Left, right, and bilateral DVT were represented in 66, 26, and 13 cases, respectively. Estimated frequencies were 2, 6.47, 5.47, 2.08, and 0.96 in the left side and 2, 1.44, 2.5, 1.33, and 1 in the right, respectively. Statistics significance was seen at the IV and FV levels. The means of minor distances in millimeters were 4.88, 3.98, 6.13, 6.20, and 4.20 in the left and 2.50, 7.00, 5.20, 7.33, and 6.50 in the right, respectively. Significance was seen only at the IV level. DVT severity and the minor distance could not be correlated with statistical significance. CONCLUSION: We consider that May-Thurner's anatomical changes impacts the DVT prevalence only at the proximal vein. We also suggest that the compression of the left iliac vein might be a contributing factor for developing DVT but not for severity of the DVT.

Purpose:
The Advanced Prostate Cancer Consensus Conference (APCCC) 2015 was based on topics withcontroversy in the field of advanced prostate cancer. To understand the Korean urologists perspective regardingthe issues, we have conducted a questionnaire named Prostate Cancer Summit (PCAS) 2016, with 9 importantsubtopics.
Materials and Methods:
Total 9 subtopics have been decided and questions were developed regarding eachsubtopic. The questions were based on that of APCCC 2015 and translated into Korean for better understanding.Total 51 panelists have voted online on 85 different questions.
Results:
The survey concluded that testosterone should be measured as a diagnostic criterion for castrationresistance prostate cancer (CRPC) and that consensus was reached on issues such as the use of androgenreceptor pathway inhibitors in the treatment of predocetaxel and postdocetaxel in CRPC patients. In addition,76% of the participants agreed that imaging tests were needed before new treatment in CRPC patients, anda majority of participants agreed that periodic imaging tests are necessary regardless of symptoms during treatmentfor CRPC. However, some issues, such as the use of prostate-specific antigen-based triggers for remediationin CRPC patients, the endocrine manipulation in nonmetastatic CRPC patients, and the onset of treatment inasymptomatic metastatic CRPC patients, were not agreed.
Conclusions
The results from PCAS 2016 has addressed some of the issues with controversy. Although thevoting results are subjective, it will help guide treatment decisions in topics with less evidence.
