The management of patients anticoagulated with warfarin and referred for coronary angiography presents a substantial challenge to the physician who must minimize risks of periprocedural hemorrhage and thromboembolism. The aim of this study was to evaluate the feasibility and safety of performing diagnostic coronary angiography and percutaneous coronary intervention during uninterrupted warfarin therapy. Patients treated with warfarin were prospectively identified and enrolled in the study. Nineteen diagnostic cardiac catheterizations and six percutaneous coronary interventions were performed in 23 patients. The mean international normalized ratio was 2.4 +/- 0.5 (range, 1.8-3.5). Hemostasis was achieved with AngioSeal following 21 procedures and with Perclose following 4 procedures. No patient experienced a predefined endpoint. Specifically, no patient experienced procedure-related myocardial infarction, major or minor bleeding. We conclude that cardiac catheterization and percutaneous coronary intervention may be considered in the setting of uninterrupted warfarin therapy. 相似文献

OBJECTIVES: It is difficult to close the empyema space once it is opened, especially in cases complicated with a chronic bronchopleural fistula. A muscle flap closure is generally employed to prevent this situation. However, this operation occasionally fails because the space newly recurs around the fistula due to atrophic change occurring in these translocated muscles. The aim of the present new technique was to prevent inspiratory pressure from the inside of the bronchus by bronchial emboli, and help the adhesion between the fistula stump and the muscle flap, even if they have become atrophic and no longer have sufficient volume to fill the entire empyema space. METHODS: We carried out fiberscopic embolism of causative bronchioles followed by muscle flap closure in 4 patients in whom open drainage had already been performed against parapneumonic empyema within the bronchial fistula. The bronchial fistula was plugged from the inside of the bronchus by silicon material, and stainless steel wire was used to connect this plug tightly to the muscle flaps, so that the fistula was sandwiched between them. In all cases, we succeeded in complete closure of the bronchial fistula and empyema space without using the omentum, and there has been no recurrence. CONCLUSION: The presented new technique was beneficial for achieving muscle flap closure of the empyema space with a chronic bronchopleural fistula. 相似文献

OBJECTIVE: For treatment of suspected pelvic abscesses, the use of the trocar technique avoids many of the technical challenges of the Seldinger method. The purpose of this study was to evaluate the effectiveness and safety of sonographically guided transvaginal aspiration or drainage with the trocar technique in suspected pelvic abscesses that were refractory to antibiotic treatment. METHODS: We retrospectively reviewed 22 patients with suspected pelvic abscesses refractory to antibiotic therapy who underwent single-step transvaginal pelvic aspiration or drainage between 1995 and 2000. RESULTS: Transvaginal aspiration or drainage was successful in 19 (86%) of the 22 patients. Of the 3 patients in whom aspiration or drainage failed, all ultimately went on to have surgery despite undergoing repeated drainage procedures. Drainage catheters were placed in 15 (68%) of the 22 patients and left in place an average of 3.7 days. Aspiration alone resulted in a 100% success rate, whereas drainage with catheter placement resulted in an 80% success rate. No complications, including bleeding, bowel perforation, and death, were reported in any of the procedures. CONCLUSIONS: Transvaginal ultrasonographically guided aspiration or catheter placement with the trocar technique is a safe and effective treatment for suspected pelvic abscesses refractory to antibiotic therapy. 相似文献

Perivalvar leak following atrioventricular valve replacement can result in heart failure or hemolytic anemia. These patients may be poor surgical candidates given a complex clinical condition. We describe transcatheter closure of a perivalvar leak in a 3-month infant who had undergone left atrioventricular valve replacement with a St. Jude's prosthesis. 相似文献

Mechanism and Etiology of Primary Chronic Angle Closure Glaucoma 总被引:2,自引:0,他引:2
Ningli Wang Zhongyao Wu Hui LiuZhongshan Opathalmic Center Sun Yat-sen University of Medical Sciences Guangzhou China 《眼科学报》1994,(3)
The ocular anatomic features, pupil-blocking force, status of angle synechiae closure and positivity of provocative tests were compared between the primary chronic angle closure glaucoma (PCACG) and primary a-cute angle closure glaucoma (PAACG) by using ultrasonic biometry, computerized anterior ocular segment image processing technique, gonioscopy and provocative tests. The studies showed that the anterior chamber depth of PAACG was shallower than that of PCACG; the pupil-blocking force of PAACG was stronger than that of PCACG; the status of angle synechiae closure of PCACG were mainly creeping synechiae closure; the positivity of mydriasis test was much higher (46. 01%) in PCACG than that (6. 8%) in PAACG after iridectomy. These facts suggest approximately half of the PCACG cases may be multi-mechanism to contribute to the angle closure besides the mechanism of pupillary block. Therefore, the authors emphasis that the pupillary block must be eliminated as well as the other mechanism for the treatment 相似文献
