RESUMO

The aim of this study was to evaluate whether the clinical outcomes were associated with socioeconomic status (SES) in patients with acute myocardial infarction (AMI) who underwent percutaneous coronary intervention (PCI). The author analyzed 2,358 patients (64.9 +/- 12.3 yr old, 71.5% male) hospitalized with AMI between November 2005 and June 2010. SES was measured by the self-reported education (years of schooling), the residential address (social deprivation index), and the national health insurance status (medical aid beneficiaries). Sequential multivariable modeling assessed the relationship of SES factors with 3-yr major adverse cardiovascular events (MACEs) and mortality after the adjustment for demographic and clinical factors. During the 3-yr follow-up, 630 (26.7%) MACEs and 322 (13.7%) all-cause deaths occurred in 2,358 patients. In multivariate Cox proportional hazards regression modeling, the only lower education of SES variables was associated with MACEs (hazard ratio [HR], 1.41; 95% confidence interval [CI], 1.04-1.91) and mortality (HR, 1.93; 95% CI, 1.16-3.20) in the patients with AMI who underwent PCI. The study results indicate that the lower education is a significant associated factor to increased poor clinical outcomes in patients with AMI who underwent PCI.

RESUMO

BACKGROUND AND OBJECTIVES: Vasospastic angina (VA) is a specific type of coronary artery disease and develops as a result of coronary artery spasm. Recently, a few studies have revealed that VA caused by coronary artery spasm is related to genetic traits. The objective of this study was to use the recently developed technique of array comparative genomic hybridization (CGH) to screen the genetic aberrations of VA. SUBJECTS AND METHODS: To identify candidate genes that might be causally involved in the pathogenesis of VA, genomic deoxyribonucleic acids were extracted from whole blood of 28 patients with VA who presented at Department of Cardiology at Seoul St. Mary's Hospital, Seoul, Korea. The copy number profiles of these patients was then analyzed using array CGH and reverse transcriptase (RT) quantitative polymerase chain reaction (PCR). RESULTS: Array CGH revealed gains in 31 different regions, with losses in the 4q35.2, 7q22.1, 10q26.3, 15q11.2, 16p13.11, 17p11.2 and 19q13.3 regions (more than 32% aberration in these regions). Several loci were found to be frequently including gains of 5p and 11q (50% of samples). The most common losses were found in 7q (54% of samples). Copy number aberrations in chromosomal regions were detected and corresponding genes were confirmed by RT quantitative PCR. The fold change levels were highest in the CTDP1 (18q23), HDAC10 (22q13.33), KCNQ1 (11p15.5-p15.4), NINJ2 (12p13.33), NOTCH2 (1p12-p11.2), PCSK6 (15q26.3), SDHA (5p15.33), and MUC17 (7q22.1) genes. CONCLUSION: Many candidate chromosomal regions that might be related to the pathogenesis of VA were detected by array CGH and should be systematically investigated to establish the causative and specific genes for VA.

RESUMO

PURPOSE: In order to establish therapeutic guidelines for TASC C & D iliac lesions, we compared outcomes of surgical and endovascular treatment. METHODS: From May 2002 to April 2007, 27 limbs of 18 patients underwent bypass operation and 23 limbs of 21 patients underwent stent placement for TASC C & D iliac lesions at Dongsan Medical Center. Age, sex, risk factor, combined diseases, clinical symptoms, treatment method, and patency rate were reviewed retrospectively. RESULTS: Technical and clinical success was achieved in all patients of the bypass group and in 95.8% of patients in the stent group. There were no complications in the surgical group, but 4 major complications in the stent group: 3 distal embolizations, and 1 arterial rupture. The primary patency rates at 6 months, 1, 2, and 3 years were all 90% in the bypass group and 95%, 89%, 89%, and 89%, respectively, in the stent group (P=0.99). The respective secondary patency rates were all 90% in the bypass group and 100%, 94%, 94%, and 94% in the stent group (P=0.56). CONCLUSION: Arterial bypass and stent placement are technically safe and effective treatment modalities in TASC C & D lesions of the iliac artery. A liberal posture to open arterial reconstruction extends the ability to treat diffuse TASC C & D lesions via endovascular means.

RESUMO

Single spore isolates of Plasmodiophora brassicae e4 and e9 obtained from diseased Chinese cabbage were identified as race 4 and race 9, respectively, by the Williams' differential variety set. To confirm the possibility of variation in same generation and progeny of a single spore isolate of P. brassicae, random amplified polymorphic DNA (RAPD) analysis was conducted using the URP 3, 6 and OPA 7 primers. There was no difference in band type at each part of the gall of Chinese cabbage obtained by inoculation of e4 and e9 and amplification using the URP 3 and 6 primers when the same generation was analyzed. In addition, the progeny analysis, which was expanded to the third generation and conducted using the URP 3 and OPA 7 primers, revealed no differences in the band type of the e4 isolate. Based on these results, the single spore isolate of P. brassicae was genetically stable.

RESUMO

The gene responsible for nail-patella syndrome, LMX1B, has recently been identified on chromosome 9q. Here we present a patient with nail-patella syndrome and an autosomal dominant pattern of inheritance. A 17-year-old girl visited our clinic for the evaluation and treatment of proteinuria. She had dystrophic nails, palpable iliac horns, and hypoplastic patellae. Electron microscopy of a renal biopsy showed irregular thickening of the glomerular basement membrane. A family history over three generations revealed five affected family members. Genetic analysis found a change of TCG to TCC, resulting in a synonymous alteration at codon 219 in exon 4 of the LMX1B gene in two affected family members. The same alteration was not detected in an unaffected family member. This is the first report of familial nail-patella syndrome associated with an LMX1B in Korea mutation, However, we can not completely rule out the possibility that the G-to-C change may be a single nucleotide polymorphism as this genetic mutation cause no alteration in amino acid sequence of LMX1B.

RESUMO

BACKGROUND AND OBJECTIVES: We hypothesized that patients with nitroglycerin-induced headache had preserved systemic vasomotion and there might be an increased nitroglycerin-mediated dilation (NMD) response in the brachial artery. The aim of this study is to evaluate whether nitroglycerin (NTG)-induced headache is associated with the level of the NMD and flow-mediated dilation (FMD) or the severity of coronary artery disease (CAD). SUBJECTS AND METHODS: The study included 87 patients (Group I: mean age: 54.8+/-9.5 years, 46 males) with headache and new onset chest pain, and 109 patients (Group II: mean age: 57.4+/-8.9 years, 67 males) without headache and with new onset of chest pain. Patients were excluded from this study if they had a history of chronic headache, long term nitrates use and coronary artery procedures. Coronary angiography was performed within one month after administering nitroglycerin for the usual clinical indications. RESULTS: The clinical characteristics did not differ between the two groups. The NMD was significantly higher in Group I than in Group II (23.0+/-7.5% vs. 18.5+/-8.6%, respectively, p<0.001). The FMD was significantly higher in Group I than in Group II (9.0+/-4.1% vs. 7.5+/-4.3%, respectively, p=0.007). On multiple regression analysis, NTG-induced headache was a predictor of CAD {oddsratio (OR), 0.04, 95% confidence interval (CI), 0.02-0.11: p<0.001, respectively}. CONCLUSION: We have shown that the vasodilator response to NTG and FMD are increased in the patients with NTG-induced headache. More NTGinduced headache developed in the patients with normal coronary arteries or minimal CAD than in the patients with obstructive CAD. This finding might be helpful as additional information for evaluating the patients with chest pain syndrome.

RESUMO

PURPOSE: We evaluated the technical feasibility and clinical efficacy of subintimal stent placement for long segment occlusion of the iliac artery. MATERIALS AND METHODS: From March 2003 to February 2007, subintimal stent placement for long segment occlusion of the iliac artery of 24 limbs in 22 patients was analyzed retrospectively. Endovascular access was performed via the ipsilateral femoral artery in 7 cases, via the contralateral femoral artery in 6 cases, via both femoral arteries in 10 cases and via the brachial artery in one case. The SAFARI (subintimal arterial flossing with antegrade-retrograde intervention) technique using a microcatheter was performed to recannalize iliac artery occlusion in three cases. Medical records were reviewed for the collection of follow-up data. The stent patency rate was analyzed by use of the Kaplan-Meier method. RESULTS: Subintimal stent placement was technically successful in 23 of 24 procedures (95.8%). The mean ankle-brachial index (ABI) increased from 0.26 to 0.82. The Fontaine classification was improved after stent placement in all patients. Major complications occurred in four procedures: three distal embolizations and one arterial rupture. All of the complications were successfully treated by endovascular intervention. The primary stent patency rates at 6-months, 1-, 2- and 3-years were 95%, 88%, 88% and 88%, respectively. CONCLUSION: Subintimal stent placement is a safe and effective treatment for long segment occlusion of the iliac artery.

RESUMO

BACKGROUND/AIMS: Transcatheter arterial chemoembolization (TACE) is a major modality in the treatment of unresectable hepatocellular carcinoma. Acute renal failure (ARF) may occur after TACE because of underlying liver cirrhosis and the presence of radiocontrast agent. However, the data available regarding this complication are variable and limited. The aim of this study was to determine the incidence and associated risk factors of ARF after TACE. METHODS: From January 2001 to December 2004, a total of 632 procedures were performed in 377 patients. Of these, the cases with high creatinine levels (> or = 2 mg/dL) before TACE and with incomplete medical records were excluded, which resulted in 463 procedures in 319 patients (256 males and 63 females; age 58.7+/-9.9 years, mean+/-SD) being examined for this study. Various clinical and radiological data before and after the procedure were reviewed retrospectively. RESULTS: ARF occurred following 15 (3.2%) of the 463 procedures within 7 days of TACE. Univariate analysis revealed that serum albumin levels (P=0.025), Model for End-Stage Liver Disease score (P=0.001), the distribution of Child-Pugh class (P=0.027), and the proportions of patients with ascites (P or = 1.5 mg/dL (P=0.023) differed significantly between patients with or without ARF after TACE. In multivariate analysis, the presence of ascites (P=0.005; odds ratio, 5.297) and serum creatinine level > or = 1.5 mg/dL (P=0.007; odds ratio, 7.358) were independently associated with the development of ARF. CONCLUSIONS: The incidence of ARF after TACE was 3.2%, and the presence of ascites and an abnormal baseline serum creatinine level were the risk factors for ARF.

RESUMO

PURPOSE: To evaluate the early ultrasonographic (US) findings from the uterus and myoma after a uterine fibroid embolization (UFE). MATERIALS AND METHODS: From March 2004 to January 2006, eleven patients (27-48 years, mean: 37 years) with UFE to treat symptomatic uterine myoma, were retrospectively reviewed. A serial follow up gray-scale and color Doppler US were performed from one day to two weeks following a UFE. The US findings were evaluated for the presence and distribution pattern of air, time of air loss, and presence of fluid collection in the uterine cavity and color Doppler (SD Comment: Doppler is name. Should perhaps be upper case) signal. RESULTS: Numerous high echoes with reverberation artifacts (which suggest air), were observed within the myoma (in all cases), one day after UFE. A branching linear echo pattern was observed in 4 cases (36%), whereas scattered echoes were observed in 7 cases (64%). Progressive loss of air, within 7 days of a UFE, was observed in 9 cases (82%), whereas 2 cases (12%) were observed within 14 days of a UFE. Abnormal fluid collection in the uterine cavity and a color Doppler signal within the myoma was not observed for all cases. CONCLUSION: Branching or scattered echoes (suggesting air), are normally found within the myoma after a UFE, but these echoes disappeared within 2 weeks. These early US findings can be useful in differentiating from myoma infections after a UFE.

RESUMO

PURPOSE: We evaluated the technical aspect and efficacy of transcatheter arterial embolization (TAE) in cases of intractable postpartum bleeding by comparing the angiographic findings women patients according to their delivery pattern. MATERIALS AND METHODS: Between July of 2003 and March of 2008, 55 female patients were enrolled in this study. Of the 55 patients, 36 underwent a vaginal delivery (group 1), whereas 19 underwent a cesarean section delivery (group 2). We retrospectively evaluated the angiographic findings and the embolization technique between groups, using a Pearson Chi-Square test. Medical records and telephone interview findings were also reviewed to evaluate the efficacy of TAE and the outcome of fertility. RESULTS: Significantly greater positive angiographic findings were found in group 2 (63.2%) relative to group 1 (30.6%). For positive angiographic findings, except for AVM, the embolization was performed using coil or glue with gelfoam. For the negative angiographic findings or AVM, the gelfoam was the only embolic agent used. In all patients except for one, bleeding stopped after embolization. Major complications occurred in 2 patients only, and included uterine synechia and perforation. All patients except for one recovered after menstruation. In total, four patients became pregnant and one patient delivered a healthy infant. CONCLUSION: Positive angiographic findings requiring embolization with coil or glue, as well as gelfoam, were more commonly encountered in group 2 than in group 1. Based on the outcome of the study group, TAE is a safe and effective treatment for intractable postpartum bleeding and is also useful for preserving fertility.

RESUMO

PURPOSE: The purpose of this study was to assess the value of the parallel wire balloon angioplasty technique for treating dysfunctional hemdialysis fistula with rigid stenosis, and this type of lesion was resistant to conventional angioplasty. MATERIALS AND METHODS: Between March 2002 and August 2003, we included 6 patients (mean age: 59, males: 2, females: 4) who were treated via parallel the wire balloon angioplasty technique and their hemodialysis fistula has stenoses that were resistant to conventional angioplasty. We performed conventional angioplasty in all patients, but we failed to achieve sufficient dilatation. In the cases of highly resistant stenosis, an additional 0.016 inch wire was inserted into the 7 F vascular sheath. During angioplasty, a 0.016 inch guide wire was inserted between the balloon and the stenosis and then it was pushed to and fro until the balloon indentation disappeared. After the procedure, we performed angiography to identify the residual stenosis and the procedure-related complications. RESULTS: The undilatable stenoses in 5 patients were successfully resolved without complications via the parallel wire angioplasty technique. In one patient, indentation of balloon was not resolved, but the residual stenosis was both minimal and hemodynamically insignificant. CONCLUSION: The parallel wire angioplasty technique seems to be a feasible and cost-effective method for treating a dysfunctional hemodialysis fistula with undilatable and rigid stenosis.

RESUMO

BACKGROUND AND OBJECTIVES: The left ventricular ejection fraction (LVEF) is known to be a significant prognostic factor for patients with acute myocardial infarction (AMI). The aim of this study was to investigate clinical or therapeutic factors associated with the recovery of a low LVEF for patients with AMI. SUBJECTS AND METHODS: From January to December 2004, we enrolled 89 patients (mean age: 62.5+/-10.6 years, 43 males and 26 females) with AMI and who had a LVEF less than 50%. Forty five patients whose LVEF improved more than 10% were classified as group I (mean age: 62.4+/-10.4 years, 34 males and 11 females) and 44 patients whose LVEF was not changed or decreased were classified as group II (mean age: 62.3+/-10.9 years, 29 males and 15 females). The clinical variables, including risk factors and the pain-to-door time, the biochemical markers of myocardial injury, the coronary angiographic findings and the treatment-related variables, were compared between the two groups. RESULTS: The cardiovascular risk factors were not different between the groups. The location of infarction, the success rate of percutaneous coronary intervention and the coronary angiographic lesion morphologies were not different between the groups. However, the pain-to-door time was significantly shorter in group I than in group II (6.0+/-9.5 vs 22.4+/-7.5 hours, respectively, p=0.046). Improved control of risk factors was not associated with the recovery of LV function. The use of beta-blocker, statin, anti-platelet agents, vasodilators and diuretics were not different between the groups. However, the use of angiotensin converting enzyme inhibitor (ACEI) was more common in group I than group II (79.3% vs 47.4%, respectively, p=0.03). CONCLUSION: A shorter pain-to-door time and the use of ACEI were significant predictors of the recovery of LV dysfunction for patients with AMI.

RESUMO

Objective: We wanted to evaluate usefulness of uncovered stent in comparison with covered stent for the palliative treatment of malignant colorectal obstruction. Materials and Methods: Covered (n = 52, type 1 and type 2) and uncovered (n = 22, type 3) stents were placed in 74 patients with malignant colorectal obstruction. Stent insertion was performed for palliative treatment in 37 patients (covered stent: n = 23 and uncovered stent: n = 14). In the palliative group, the data on the success of the procedure, the stent patency and the complications between the two groups (covered versus uncovered stents) were compared. Results: The technical success rate was 89% (33/37). Symptomatic improvement was achieved in 86% (18/21) of the covered stent group and in 92% (11/12) of the uncovered stent group patients. The period of follow-up ranged from three to 319 days (mean period: 116+/-85 days). The mean period of stent patency was 157+/-33 days in the covered stent group and 165+/-25 days in the uncovered stent group. In the covered stent group, stent migration (n = 11), stent fracture (n = 2) and poor expansion of the stent (n = 2) were noted. In the uncovered stent group, tumor ingrowth into the stents (n = 3) was noted. Conclusion: Self-expanding metallic stents are effective for relieving malignant colorectal obstruction. The rate of complications is lower in the uncovered stent group than in the covered stent group.

RESUMO

The incidence of acute deep vein thrombosis after multiple trauma has been reported to range from 1.7 to 10%. In general, a thrombus of the calf vein migrates to the proximal vein. An isolated inferior vena cava (IVC) thrombosis without a peripheral venous thrombosis is rare. A 35-year-old woman was admitted as a result of a large subcapsular hematoma in the right hepatic lobe after a blunt injury caused by an automobile accident. The thrombus in the IVC was detected incidentally during a follow up CT scan three weeks after the trauma. A compression of the IVC by the displaced hepatic parenchyme as a result of a large subcapsular hematoma is a possible mechanism for the IVC thrombosis because there was no distal venous thrombosis and no evidence of hypercoagulability. A retrievable caval filter (Gunther-Tulip(TM), Cook Inc. Bloominton, USA) was placed in the suprarenal vena cava via the right internal jugular venous approach. After placing the retrieval caval filter, aspiration thrombectomy was attempted through the right femoral vein. The luminal patency of the IVC was restored immediately after retrieving the thrombus. The subcapsular hematoma in the right hepatic lobe disappeared two months later and there was no evidence of a residual thrombus in the inferior vena cava.

RESUMO

We report here on a case of spontaneous rupture of the left common iliac vein that was diagnosed preoperatively with computed tomography (CT), and the patient was successfully treated with surgery and stent placement. A 60-year-old woman was referred to our emergency room because of sudden left lower abdominal pain and swelling of the left lower extremity. CT revealed a huge retroperitoneal hematoma and extrinsic compression of the left common iliac vein with acute thrombosis of the deep veins of the left lower extremity. Venous patch angioplasty was performed at the site of spontaneous rupture. After performing thrombectomy with using a Forgaty catheter, a stent was placed at the occluded segment of the left common iliac vein under C-arm fluoroscopic guidance. The follow-up CT scans taken at 10 days and 8 months after the initial examination demonstrated a venous stent with preserved luminal patency and the striking resolution of the deep vein thrombosis of the left lower extremity.

RESUMO

For the patients suffering from extensive deep vein thrombosis (DVT), the placement of an inferior vena cava (IVC) filter in conjunction with anticoagulant therapy has been used to prevent pulmonary embolisms. However, for the patients who anticoagulant is contraindicated or if this is complicated, the use of an IVC filter without concurrent anticoagulation may become the sole treatment for pulmonary embolisms. In this situation, the thrombi trapped in the IVC filter may cause significant clinical problems. We report here on a case of IVC filter thrombosis that was successfully treated by aspiration thrombectomy after placing another filter proximal to the previous filter.

RESUMO

PURPOSE: We wanted to evaluate the procedural success after percutaneous treatment of thrombosed native arteriovenous dialysis fistula insufficiency and the efficacy of performing mechanical thrombectomy with using the stone basket. MATERIALS AND METHODS: From March 2004 to June 2005, 36 thrombosed native hemodialysis access shunts in the upper limbs (brachiocephalic fistulas: 16 and radiocephalic fistulas: 20) were percutaneously treated in 30 patients. Declotting procedures were performed with using urokinase (100,000-200,000 unit) and manual catheter-directed thrombo-aspiration in all the patients. Angioplasty (6 mm in diameter and 4 cm in length) was performed at the identified area of the stenosis and/or with maceration of the thrombus. In 14 cases with massive thrombosis that was refractory to the above mentioned declotting procedures, mechanical thrombectomy with using a Wittich nitinol stone basket (Cook, Bloomington, IN) was performed. Data regarding the procedural success rate and the patency rate were analyzed by means of Fischer's exact test, and the Kaplan-Meier method with the Log-rank test was used for statistical inter-group comparisons between the brachiocephalic and radiocephalic fistulas. RESULTS: Successful declotting and restoration of thrill were achieved in 30 of 36 procedures (83%). Reestablishment of normal dialysis for at least one session was achieved in 29 of 36 procedures (81%). The procedural success rate for the brachiocephalic fistulas was 94% compared with 70% for the radiocephalic fistulas, but the difference was not statistically significant (p=0.104). In the cases with performing mechanical thrombectomy and using the stone basket, procedural success was achieved in 93% (13/14). The expected patency rates at 3, 6 and 12 months were 78%, 61% and 51%, respectively. The patency rates after declotting procedures were not significantly different between the brachiocephalic and radiocephlaic fistulas (p=0.871). CONCLUSION: Percutaneous treatment of thrombosed native arteriovenous dialysis fistula insufficiency showed an excellent success rate and patency rate, and especially performing mechanical thrombectomy with using the stone basket could increase the procedural success rate.

RESUMO

BACKGROUND/AIMS: Although balloon-occluded retrograde transvenous obliteration (BRTO) has been used as a new procedure for gastric variceal bleeding due to its feasibility and minimal invasiveness, reports regarding the results of BRTO are not well presented in Korea. Therefore, we analyzed the results of our experience in recent 39 months. METHODS: Twenty eight patients who received BRTO for primary hemostasis or secondary prevention of gastric variceal bleeding from December 2001 to March 2005 were analyzed retrospectively. RESULTS: Twenty three men and five women were involved, and the mean age was 53.7+/-9.6 years. Technical and clinical success rates were 89.3% and 85.7%, respectively. Follow-up duration was 17.5+/-12.5 months in 23 patients. Gastric varices disappeared in 78.3% and decreased in 21.7%. Relapses occurred in 4.3% of the patients. Preexisting hepatic encephalopathy improved in all 11 patients. Aggravation of ascites, esophageal varices, portal hypertensive gastropathy were observed in 45.8%, 30.4%, 56.5%, respectively. Increased Child-Pugh score (p<0.001) and decreased albumin concentration (p=0.002) were observed 3 days after BRTO, but resolved 7 days later. Increased albumin concentration and decreased Child-Pugh score maintained thereafter. Rebleeding occurred in 3 patients which were caused by esophageal varices. Two-year survival rate was 54.6%. Presence of hepatocellular carcinoma (HCC) (p=0.001) and Child-Pugh grade (p=0.033) affected the survival, but HCC was the only independent risk factor (p=0.010, OR=15.837) in multivariate analysis. CONCLUSIONS: BRTO is an effective therapeutic procedure for primary hemostasis, secondary prevention, and for improving survival in gastric variceal bleeding patients.

RESUMO

BACKGROUND/AIMS: Prognosis of advanced hepatocellular carcinoma (HCC) treated by conventional therapies has been considered to be poor. The aim of this study was to evaluate the efficacy of hepatic arterial infusion therapy (HAIT) using FEM (5-fluorouracil, epirubicin, mitomycin-C) regimen for advanced HCC. METHODS: Eighteen patients received repeated HAIT using an implanted drug delivery system. Of the 18 patients, 8 patients had HCC with portal vein tumor thrombosis, 9 patients had recurrent HCC after transarterial chemoembolization (TACE) and 1 patient after surgical resection. The patients received 5-fluorouracil (330 mg/m2, every week), epirubicin (30 mg/m2, every 4 weeks) and mitomycin-C (2.7 mg/m2, every 2 weeks). RESULTS: Mean age was 51 years. The response rate (complete response+partial response) by tumor size on abdominal CT was 38.9%. Survival ranged from 2 to 24 months and the median survival time was 8 months. The cumulative survival rate of responders group was significantly higher than non-responders group (p=0.0385). The mean levels of serum alpha-FP and PIVKA-II in responders group decreased after HAIT (3,179 ng/mL and 2,850 ng/mL) than before (11,218 ng/mL and 4,396 ng/mL), but not significantly. Chemotherapy-related side effects were nausea, vomiting and alopecia. Three patients had catheter-related complications. One patient developed gastric ulcer. CONCLUSIONS: HAIT using FEM regimen is a useful therapeutic option for patients with advanced HCC with portal vein tumor thrombosis or ineffective response to other therapies.
