  • Background: All the patients with mechanical valves require warfarin therapy in order to prevent them from developing thromboembolic complications. According to the ACC/AHA practice guidelines, after AVR with bileaflet mechanical prostheses in patients with no risk factors, warfarin is indicated to achieve an INR of 2.0 to 3.0. After MVR with any mechanical valve, warfarin is indicated to achieve an INR of 2.5 to 3.5. But in our clinical experience, bleeding complications (epistaxis, hematuria, uterine bleeding, intracerebral hemorrhage etc.) frequently developed in patients who maintained their INR within this value. So, we retrospectively reviewed the patients with bileaflet mechanical heart valve prosthesis and we determined the optimal anticoagulation value. Material and Method: From January 1984 to February 2007, 311 patients have been followed up at a national medical center. We classified the AVR patients (n=60) into three groups as follows: an INR from 1.5 to 2.0 in Group I, an INR from 2.0 to 2.5 in Group II and an INR from 2.5 to 3.0 in Group III. We classified the MVR (n=171) and DVR (n=80) patients into four groups as follows: an INR from 1.5 to 2.0 in Group I, an INR from 2.0 to 2.5 in Group II, an INR from 2.5 to 3.0 in Group III and an INR from 3.0 to 3.5 in Group III. We compared the groups for their thromboembolic and bleeding complications by means of the Kaplan Meier method. Result: In the AVR patients, 2 thromboembolic complications and 4 bleeding complications occurred and the log rank test failed to identify any statistical significance between the groups for thethromboembolic complication rate, but groups I and II had lower bleeding complication rates than did group III. Thirteen thromboembolic complication and 15 bleeding complication occurred in the MVR and DVR patients, and the log rank test also failed to identify statistical significance between the groups for the thromboembolic complication rate, but groups I and II had lower bleeding complication rates that did groups III and IV. Conclusion: The thromboembolic complication rate was not statistically different between groups I and II and groups III and IV, but the bleeding complication rates of groups I and II were lower than those of groups III and IV. So this outcome encouraged us to continue using our low intensive anticoagulation regime, that is, an INR of 1.5 to 2.5.

  • Gastrointestinal complications, especially duodenal complication after cardiopulmonary bypass are rare, but often fatal. We experienced 1 case of duodenal ulcer bleeding and 2 cases of duodenal ulcer perforation developing after cardiopulmonary bypass from August 1994 to April 1996. In the case of duodenal ulcer bleeding, palpitation, dizziness, tachycardia and melena were the clues leading to diagnosis, and in the cases of perforation, abdominal distension with pain, tachycardia, hypotension, oliguria were the clues. Duodenal perforations were diagnosed by abdominal paracentesis. The patient with duodenal bleeding was treated by H-2 receptor antagonist, antacids and transfusion. And emergency laparotomy was required for the patients with duodenal perforation. In addition to ulcer prophylaxis including H-2 receptor antagonist and antacids, a high index of suspicion and timely surgery are necessary for early diagnosis and appropriate treatment of duodenal complication developing af er cardiopulmonary bypass.

  • Purpose: The purpose of this study was to examine the effect of position change on the level of comfort and occurrence of bleeding after transarterial chemoembolization. Methods: This study was the nonequivalent control group non-synchronized design. The experimental group was positioned in supine with 15-30 degree Semi-folwer's position for 2 hours and then changed supine position alternatively to 30 degree lateral positioning in turn per hour for 2 hours. For the control group, 6 hour supine positions without any position change were applied. Results: The level of discomfort of the control group was scored higher level than that of the experimental group. There was no significant differences in back pain and the degrees of voiding difficulty. There were no significant differences in the incidence of bleeding complication between the two groups. Conclusion: The position change in patients after transarterial chemoembolization could be applied without any severe side effects such as bleeding complication, but it was revealed to be effective in reducing the level of discomfort.

  • Although sodium hypochlorite is the most frequently used canal irrigant during endodontic treatment, its complications are not as well recognized as its effectiveness. This report demonstrates that sodium hypochlorite extrusion during endodontic treatment can cause severe complications. A 5-year-old boy experienced immediate pain and swelling, ecchymosis in surrounding tissues, and profuse bleeding from the root canal during endodontic treatment, because of accidental extrusion of sodium hypochlorite. The patient was hospitalized, and analgesics and antibiotics were prescribed. Accidental extrusion of the irrigating solution occurs more frequently in teeth with immature apices, root resorption, and apical perforations; therefore, caution is needed. When such complications occur, proper management and medications are needed.

  • Hereditary hemorrhagic telangiectasia is a rare autosomal dorminant disease that features abnormal and fragile vascular dilations of terminal vessels in skin and mucous membranes, as well as arteriovenous malformations of internal organs, particularly lungs, brain, and liver. Often patients have not been diagnosed with HHT for a long time, and undiagnosed HHT patients unnecessarily develop serious complications such as severe life-threatening hemorrhage, stroke or brain abscess. Therefore, early detection and appropriate screening is very important. Early detection of HHT allows the appropriate screening for the presence of silent disease such as AVMs in the lungs, liver, or brain, and preventive treatment in the patient and their affected family members. Dentists should be familiar with HHT because the telangiectases on skin and oral mucosa are often the most dramatic and most easily identified component of HHT. Recently, we experienced a case of HHT. We present the case with a review of the literature.

  • Purpose: This study was to test the effects of the positional change on low back pain, discomfort, and bleeding complications during the period of bed rest following transarterial chemoembolization (TACE). Methods: The research design for this study was a non-equivalent control group quasi-experimental design. The participants were 23 patients for the experimental group, and 23 patients for the control group. The experimental group received positional change of taking the semi-Fowler's position and the 30-degree lateral position alternatively during the period of bed rest after TACE for 4 hours at one-hour intervals. The control group maintained the supine position continuously during the period of bed rest after TACE. Results: There were statistically significant differences in low back pain and discomfort between the experimental and the control group after intervention. And no significant difference was found in bleeding complication between two groups. Conclusion: The results of the study suggest that the positional change is an effective nursing intervention to reduce low back pain and discomfort without increasing the risk of bleeding after TACE.

  • Purpose: This study was a retrospective cohort study to evaluate the effect of evidence-based guidelines for catheter dysfunction among hemodialysis patients, Success rate and bleeding complications in catheterization were examined. Methods: We performed a retrospective cohort study, including 94 patients with catheter dysfunction who were receiving hemodialysis at a university hospital; 55 in the control group and 39 in the protocol group. This protocol was composed of the catheter dysfunction assessment, conservative management of catheter dysfunction, drug management of catheter dysfunction, catheter function test and maintenance management. Data were analyzed with a Chi-square test and t-test using SPSS/WIN 23.0 program. Results: The patency rate of the protocol group was significantly higher than that of the control group. The rate of bleeding complications was not statistically significant for either the control group or the protocol group before or after application. Conclusion: The application of the guidelines effectively increased the patency rate of the catheter without bleeding complications. It is hoped that this guideline can be disseminated to nurses nationwide to improve the efficiency of catheter function for hemodialysis patients.

  • Most low-energy pelvic ring fractures in elderly patients are treated conservatively so that an initial evaluation for complications such as vascular injury is usually overlooked. An 81-year-old female, who was taking regular aspirin, visited the emergency room and was diagnosed with a simple non-displaced pubic ramus fracture from a low-energy fall from standing, which was complicated by massive hemorrhage from the overlooked injury of the corona mortis. Elderly patients with pelvic ring fractures can have a delayed presentation of vascular injuries, regardless of the degree of displacement of the fractures, which highlights the need for a careful physical examination and close monitoring.

  • Endometriosis-related symptoms are believed to be alleviated during pregnancy. However, pregnancy complications, such as pseudoaneurysm of the uterine artery, rupture of ovarian or uterine vessels, and intraabdominal bleeding from decidualized deep infiltrating endometriosis (DIE) lesion have been rarely reported. Owing to the potential risk of rupture and resultant life-threatening complications, proper diagnosis and close monitoring of decidualized endometriotic lesion are very important despite its low relative risk. Till date, massive vaginal bleeding from decidualized rectovaginal DIE during pregnancy has not been in English literatures. Here, we present the first case of spontaneous massive vaginal bleeding due to decidualized rectovaginal DIE that occurred in the late third trimester of pregnancy.
