Ultrasound (US)-guided fine needle aspiration (US-FNA) has played a crucial role in managing patients with thyroid nodules, owing to its safety and accuracy. However, even with US guidance, nondiagnostic sampling and infrequent complications still occur after FNA. Accordingly, the Task Force on US-FNA of the Korean Society of Thyroid Radiology has provided consensus recommendations for the US-FNA technique and related issues to improve diagnostic yield. These detailed procedures are based on a comprehensive analysis of the current literature and from the consensus of experts.

BACKGROUNDAmerican College of Cardiology/American Heart Association/European Society of Cardiology (ACC/AHA/ESC) guidelines gave fondaparinux a class I recommendation for use in patients with non-ST elevation acute coronary syndromes (NSTE-ACS) undergoing invasive or conservative strategy. Nadroparin is one of the common anticoagulants used in NSTE-ACS in China. Accordingly, this study compared the safety and efficacy between fondaparinux and nadroparin in patients with NSTE-ACS.

METHODSIn this prospective, randomized, open-label, and single center study, a total of 300 patients with NSTE-ACS were randomized to receive either fondaparinux (group F, n = 150, 2.5 mg/d) or nadroparin (group N, n = 150, 0.1 ml/10 kg q12 h) for a mean of 4 days. The primary safety endpoint was the incidence of major or minor bleeding at 9 days that was not related to coronary artery bypass grafting (CABG). The primary efficacy endpoints included death, myocardial infarction, or recurrent ischemia at 9 days. All patients underwent a 180-day follow-up.

RESULTSBaseline characteristics were well matched between the two groups. There was a non-significant 28% relative risk reduction in the primary safety endpoint in group F compared with group N (4.7% vs. 6.7%, HR 0.72, 95%CI 0.42-1.65, P = 0.38). The primary efficacy endpoint was 8.0% in group F and 10.0% in group N (HR, 0.82, 95%CI 0.54-1.71, P = 0.49). The composite of the safety and efficacy endpoints at 9 days (10.0% vs. 16.0%, HR 0.61, 95%CI 0.31-1.10, P = 0.10), 30 days (14.0% vs. 17.9%, HR 0.72, 95%CI 0.47-1.16, P = 0.21), or 180 days (18.7% vs. 27.3%, HR 0.65, 95%CI 0.38-1.11, P = 0.11) showed a non-significant trend toward a lower value in group F.

CONCLUSIONFondaparinux resulted in a nonsignificant risk reduction in patients with NSTE-ACS in both bleeding and ischaemic events during short- and long-term follow-up compared with nadroparin.

Objective: To evaluate different methods' efficacy of controlling acute bleeding and managing long-term menstruation in patients with heavy menstrual bleeding (HMB) associated with antithrombotic therapy. Methods: The clinical data of 22 cases with HMB associated with antithrombotic therapy admitted to Peking University People's Hospital from January 2010 to August 2022 were analyzed, aged 39 years old (26-46 years). Changes in menstrual volume, hemoglobin (Hb), and quality of life were collected after control of acute bleeding and long-term menstrual management. Menstrual volume was assessed by pictorial blood assessment chart (PBAC), and quality of life was assessed by menorrhagia multi-attribute scale (MMAS). Results: (1) Treatment of acute bleeding: of the 22 cases with HMB associated with antithrombotic therapy, 16 cases were treated in our hospital and 6 in other hospital for emergency bleeding; of the 16 cases treated in our hospital, 3 underwent emergency intrauterine Foley catheter balloon compression due to severe bleeding (Hb decreased by 20 to 40 g/L within 12 hours). Of the 22 cases with antithrombotic therapy-related HMB, 15 (including 2 cases with severe bleeding) underwent emergency aspiration or endometrial resection, and intraoperative placement of levonorgestrel-releasing intrauterine system (LNG-IUS) followed by a significant reduction in bleeding volume; 3 cases had controlled acute bleeding after rivaroxaban dose reduction and continued observation; 2 cases were given gonadotropin-releasing hormone agonists to control acute bleeding in other hospital, of which 1 case was temporarily treated with periodic blood transfusion, and the other one patient underwent total hysterectomy; and 2 cases had temporary amenorrhea with oral mifepristone after intrauterine balloon compression or oral norethindrone. (2) Long-term menstrual management: of the 22 cases with antithrombotic therapy-related HMB, 15 had LNG-IUS placement and 12 had LNG-IUS placement for 6 months, and menstrual volume was significantly reduced [PBAC scores were 365.0 (272.5-460.0) vs 25.0 (12.5-37.5), respectively; Z=4.593, P<0.001], Hb was significantly increased [91.5 g/L (71.8-108.2 g/L) vs 128.5 g/L (121.2-142.5 g/L); Z=4.695, P<0.001], and quality of life was significantly improved [MMAS scores were 415.0 (327.5-472.5) vs 580.0 (570.0-580.0), respectively; Z=-3.062, P=0.002] before placement compared with 6 months after placement. Three rivaroxaban dose reduction patients' PBAC scores decreased by 20 to 35 but remained >100, and perceived quality of life did not change significantly. Two cases with temporary amenorrhea treated with oral mifepristone felt significantly improved quality of life, and the MMAS scores increased by 220 and 180, respectively. Conclusion: Intrauterine Foley catheter balloon compression, aspiration or endometrial ablation could be used to control acute bleeding in patients with antithrombotic therapy-related HMB, and LNG-IUS for long-term management could reduce menstrual volume, increase hemoglobin, and improve the quality of life of patients.

OBJECTIVETo assess the effect and safety of therapies in common use for acute myocardial infarction (AMI) patients with failed thrombolytic therapy.

METHODSWe searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 2, 2006), MEDLINE (1966 to July 2006), EMBASE (1984 to July 2006), China National Knowledge Infrastructure (CNKI, 1994 to July 2006), China Biomedicine Database disc (CBMdisc, 1980 to July 2006). We also searched several key Chinese journals in the field of cardiovascular diseases. The language was limited to Chinese and English. We included all the randomized controlled trials (RCTs) for acute myocardial infarction patients with failed thrombolytic therapy. Two authors independently assessed the methodological quality of the included studies, the data were analyzed by RevMan 4.2.8 from the Cochrane Collaboration.

RESULTSNine RCTs met the inclusion criteria. A significant difference was found between the rescue percutaneous coronary intervention (PCI) group and conventional treatment group in the mortality rate at the end of the follow-up [RR=0.64, 95%CI (0.41, 0.98)]. Thromboembolic stroke and bleeding in rescue PCI group were significantly higher than that in conventional treatment group [RR=4.39, 95%CI (1.14, 16.87), and RR=2.79, 95%CI (1.55, 5.02), respectively]. Compared with conventional therapy, rescue thrombolytic treatment was associated with a significantly higher reperfusion rate [RR=2.92, 95%CI (1.75, 4.85)]. Comparison between rescue PCI with rescue thrombolytic treatment revealed that the revascularization rate in rescue PCI group was significantly lower than that in rescue thrombolytic group [RR=0.57, 95%CI (0.34, 0.95)], and the incidence of bleeding was significantly higher in rescue PCI group [RR=2.15, 95%CI (1.27, 3.63)]. Comparison of glycoprotein (GP)IIb/IIIa receptor antagonists with standard treatment showed no significant difference between them in the mortality rate and bleeding rate at the end of the follow-up.

CONCLUSIONCurrent evidence does not confirm the effect or safety of the therapies for AMI patients with failed thrombolytic therapy, nor support the routine use of these therapies in clinical practice except for rescue PCI that reduces mortality compared with traditional treatment. Further high-quality randomized controlled trials are needed to provide reliable evidence for the treatments of AMI patients with failed thrombolytic therapy.

BACKGROUNDTirofiban has been widely used as an adjunctive pharmacologic agent for revascularization in patients undergoing percutaneous coronary intervention, and the outcomes appear attractive. However, the potential benefits from early administration of tirofiban in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) remain unclear.

METHODSWe conducted a search in MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials up to September 2012 without language restriction. A total of eight randomized trials (n = 1 577 patients) comparing early (emergency department or ambulance) versus late (catheterization laboratory) administration of tirofiban in STEMI patients undergoing PPCI were included in this meta-analysis. Risk ratio (RR) was computed from individual studies and pooled with random- or fixed-effect models.

RESULTSThere were no differences in post-procedural Thrombolysis In Myocardial Infarction (TIMI) flow grade 3 and Corrected TIMI Frame Count (RR = 1.02, 95% confidence interval (CI): 0.99-1.05, P = 0.18; weighted mean difference (WMD) = -0.93, 95% CI: -5.37-3.52, P = 0.68, respectively) between the two groups. Similarly, there were no significant differences in the incidence of 30-day mortality (RR = 1.69, 95% CI: 0.69-4.13, P = 0.25) and re-myocardial infarction (RR = 0.71, 95% CI: 0.21-2.35, P = 0.57) between early and late administration of tirofiban. As to the safety end points, no significant difference was observed in hospital minor bleeding (RR = 1.08, 95% CI: 0.54-2.14, P = 0.83) and hospital and 30-day major bleeding between the two groups (RR = 0.98, 95% CI: 0.46-2.10, P = 0.96; RR = 1.32, 95% CI: 0.59-2.97, P = 0.49, respectively).

CONCLUSIONSEarly administration of tirofiban in patients undergoing PPCI for STEMI was safe, but no beneficial effects on post-procedural angiographic or clinical outcomes could be identified as compared with late administration. Besides the negative finding, more high-quality randomized clinical trials are still needed to explore the efficacy of adequate, earlier administration of tirofiban in patients undergoing PPCI.

OBJECTIVE: To determine the efficacy and outcome of percutaneous treatment in restoring the function of failed native arteriovenous fistulas (AVFs) where pulse-spray pharmacomechanical thrombolysis was used as the primary mode of therapy. MATERIALS AND METHODS: From June 2001 to July 2005, 14 patients who had thrombosis of native AVFs underwent percutaneous restoration following 20 episodes of thrombosis. These included 6 repeated episodes in one forearm AVF and two episodes in another forearm AVF. All patients except one were treated with urokinase injection utilizing the pulse-spray technique and had subsequent balloon angioplasty. One patient was treated by percutaneous angioplasty alone. We retrospectively evaluated the feasibility of percutaneous treatment in restoring the function of the failed AVFs. The primary and secondary patencies were calculated by using a Kaplan-Meier analysis. RESULTS: Both technical and clinical success were achieved in 15 (75%) of 20 AVFs. Four of the five technical failures resulted from a failure to cross the occluded segment. One patient refused further participation in the trial through a brachial artery access following failure to cross the occluded segment via an initial retrograde venous puncture. There were no major precedure related complications observed. Including the initial technical failures, primary patency rates at six and 12 months were 64% and 55%, respectively. Secondary patency rates at six and 12 months were 71% and 63%, respectively. CONCLUSION: Pulse-spray pharmacomechanical thrombolysis for treatment of the thrombosed AVFs is safe, effective and durable. This procedure should be considered as an option for the management of failed AVFs prior to surgical intervention.

BACKGROUND/AIMS: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful for the pathological diagnosis of pancreatic masses, but patients are susceptible to severe bleeding and perforation. Because the incidence and severity of these complications have not been fully evaluated. METHODS: We aimed to evaluate severe bleeding and perforation after EUS-FNA for pancreatic masses using large-scale data derived from a Japanese nationwide administrative database. RESULTS: In total, 3,090 consecutive patients from 212 low- to high-volume hospitals were analyzed. Severe bleeding requiring transfusion or endoscopic treatment occurred in seven patients (0.23%), and no perforation was observed. No patient mortality was recorded within 30 days of EUS-FNA. The rate of severe bleeding in low-volume hospitals was significantly higher than that in medium- and high-volume hospitals (0.48% vs 0.10%, p=0.045). CONCLUSIONS: Severe bleeding and perforation following EUS-FNA for pancreatic masses are rare, and the procedure is safe.
