The purpose of this study was to evaluate the effect of single antiplatelet treatment on delayed bleeding, in patients undergoing dental extraction. A total of 154 teeth were extracted in 94 patients with ongoing antiplatelet treatment, who were taking single antiplatelet of either aspirin or clopidogrel. All patients underwent simple dental extraction; local hemostasis was performed with gauze-biting, suturing, and/or application of a local hemostatic agent. Delayed bleeding was recorded in 5 teeth out of a total of 154 teeth after extraction, the incidence of postoperative delayed bleeding being 3.2%. The bleeding was controlled by the patients themselves, through application of pressure with additional gauze-biting. No one visited the doctor or emergency room for hemostasis. These results confirmed that patients taking single antiplatelet drugs may have teeth extracted safely without interruption of the antiplatelet treatment.

The use of novel oral anticoagulants (NOACs) has increased in recent times in an effort to overcome the shortcomings of warfarin. They are being used primarily for the prevention of thrombosis caused by atrial fibrillation and offer the advantages of having fewer drug interactions than warfarin, no dietary restrictions, and no requirement for regular blood tests. Although there is reportedly less postoperative bleeding even if the drug is not discontinued during procedures that can cause local bleeding, such as dental procedures, no well-designed clinical studies have assessed postoperative bleeding associated with the use of these drugs. This article reports a case of a 74-year-old male patient who was taking rivaroxaban. The patient underwent a dental implant procedure after discontinuing rivaroxaban for one day and subsequently suffered delayed bleeding on postoperative day 6. Accordingly, this article also reports that the use of NOACs may also lead to delayed bleeding.

A Le Fort I osteotomy is a common procedure for correcting dental and facial deformities in orthognathic surgery. In rare cases, a delayed hemorrhage can occur as early as several hours or up to 12 weeks, postoperatively. The most frequently involved blood vessels in a delayed hemorrhage are the descending palatine artery, the internal maxillary artery, and the pterygoid venous plexus of veins. Intraoral bleeding accompanied by severe epistaxis in these cases makes it difficult to locate the precise bleeding focus. Eventual uncontrolled bleeding would require Merocel packing or surgical intervention. In general, a severe late postoperative hemorrhage is most effectively managed by angiography and embolization. Herein we describe a delayed hemorrhage case in which the cause was not evident on angiography. We were able to detect the bleeding point through an endoscopic nasal approach and treat it using direct cauterization.

Excessive oral and maxillofacial bleeding causes upper airway obstruction, bronchotracheal & gastric aspiration and hypovolemic shock. Therefore, the rapid & correct bleeding control is very important for life-saving in the medical emergency room. In spite of the bleeding control methods of the wound suture & direct pressure, the postoperative bleeding can be occurred, because of the presence of various bleeding disorders & postoperative delayed wound infections. The proper care of bleeding disorders & wound infections are very important for the control of the delayed postoperative rebleeding. In spite of these methods, active oral bleeding can be presented by the other causes of head injury. A rare but particularly dangerous sort of bleeding that may have an especial importance to the patient with severe basal skull fracture that damage large vessels and even the cavernous sinus. The occurrence of profuse nasal or oropharyngeal bleeding may arise from damage to the anterior and posterior ethmoidal vessels, but when mixed with brain tissue it is evidence of mortal damage. In this condition, rapid entire oropharyngeal packing is essential for the control of active oral bleeding. This is a case report of rapid rational bleeding control method by much amount of wet gauze packings, in a 44-years-old male patient with active oropharyngeal bleeding by basal skull fractures.

서 론 : 객혈환자에서 기관지경술은 객혈의 원인질환을 진단하고 출혈위치를 진단하기 위한 중요한 검사이지만 시행하는 시기에 대해서는 논란이 있다. 객혈중이나 객혈 후 48시간내에 시행하는 조기기관지경술이 객혈 48시간후에 시행하는 후기기관지경술에 비해 출혈을 확인하는 율이 높다고 알려져 있지만 보고자에 따라 출혈부위의 진단율은 차이가 있으며 안정성에도 이견이 있다. 이에 자자들은 객혈환자에서 기관지경의 시기에 따른 안전성과 유용성을 평가하기 위해서 다음과 같은 연구를 하였다. 대상 및 방법 : 1994년 10월부터 1996년 8월까지 객혁을 주소로 삼성서울병원에 내원하여 기관지경술을 시행받은 환자를 대상으로 하였다. 기관지정 시행시기의 구분은 1995년 5월부터 1996년 8월까지 객혈을 주소로 응급실에 내원한 환자는 부득이한 사정을 제외하고 모두 48시간 이내에 기관지경을 시행하여 조기기관지경군으로, 48시간 이후에 시행한 환자는 후기기관지경군으로 삼아 출혈부위의 진단율, 객혈원인의 진단율, 기관지경과 관련된 합병증, 조기기관지경이 객혈의 치료 방침에 영향을 주었는지 여부 등을 비교하였다. 결 과 : 조기기관지경군은 71명을 대상으로 73회의 기관지경을 시행하였고 후기기관지경군은 55명의 환자를 대상으로 57회의 기관지경을 시행하였다. 객혈량과 객혈의 원인질환 따른 양군간의 유의한 차이는 없었다. 조기기관지경군의 경우 활동성 출혈이 있어서 출혈부위를 진단한 예가 28예(38.3%)로 후기기관지경군의 5예(8.7%)보다 유의하게 많았으며 (p < 0.05), 응혈을 제거하고 난 다음 출혈이 있어 출혈부위를 확인한 예는 각각 8예, 10예이었다. 전체적인 출혈부위 진단율은 조기 및 후기기관지경에서 36예(49.3%), 15예(26.3%)이었다(p>0.05). 객혈의 원인질환에 대한 진단율은 조기기관지경군에서 18예(25.3%), 후기기관지경군에서 16예(29%)로 두 군간의 유의한 차이는 없었다(p>0.05). 기관지경 결과가 치료에 영향을 준 경우는 조기기관지경군에서 수술을 시행한 6예의 환자중 4예에서 수술전 기관지경으로 출혈부위를 진단하여 수술을 시행하였고 후기기관지경군에는 수술한 4예중 1예에서만 수술전출혈부위가 진단되었다. 조기기관지경군에서 3예는 기관지경 시행후 치료방침을 조기에 결정하여 치료를 시작할 수 있었다. 기관지경과 관련된 합병증으로 조기기관지경을 시행한 2예(2.7%)에서 100cc 이상의 출혈을 보였고 이외에 조기 및 후기기관지경군에서 주요 합병증은 관찰되지 않았다. 결 론 : 객혈환자에서 객혈 후 48시간내에 시행하는 조기기관 지경술은 48시간이후에 시행하는 후기기관지경술보다 합병증의 증가없이 출혈부위를 정확하게 파악할 수 있는 시술이라 생각된다.

Purpose: The use of direct oral Xa inhibitors (DXaIs) to prevent venothrombotic events is increasing. However, gastrointestinal bleeding, including that related to endoscopic resection, is a concern. In this study, we evaluated bleeding and coagulation times during the perioperative period of gastric endoscopic submucosal dissection (ESD). Materials and Methods: Patients who consecutively underwent gastric ESD from August 2016 to December 2018 were analyzed. Bleeding rates were compared among the 3 groups (antiplatelet, DXaIs, and control). DXaI administration was discontinued on the day of the procedure. Prothrombin time (PT), activated partial thromboplastin time, and the ratio of inhibited thrombin generation (RITG), which was based on dilute PT, were determined before and after ESD. Results: During the study period, 265 gastric ESDs were performed in 239 patients, where 23 and 50 patients received DXaIs and antiplatelets, respectively. Delayed bleeding occurred in 17 patients (7.4%) and 21 lesions (7.1%). The bleeding rate in the DXaI group was significantly higher than that in the other groups (30.4%, P<0.01), and the adjusted odds ratio of bleeding was 5.7 (95% confidence interval, 1.4-23.7; P=0.016). In patients using DXaIs, there was a significant (P=0.046) difference in the median RITG between bleeding cases (18.6%) and non-bleeding cases (3.8%). Conclusions: A one-day cessation of DXaIs was related to a high incidence of bleeding after gastric ESD, and monitoring of residual coagulation activity at trough levels might enable the predicted risk of delayed bleeding in patients using DXaIs.

Posttraumatic pseudoaneurysm of the face is caused by blunt, penetrating, or surgical trauma. Although its incidence is low, pseudoaneurysm rupture can cause a life-threatening, massive hemorrhage. A 48-year-old man visited our emergency center due to a fall-down accident. Three-dimensional computed tomography (CT) showed a comminuted zygomaticomaxillary complex fracture of the left face. After open reduction and internal fixation, the surgical wound healed without any complications. However, the patient was readmitted 10 days after surgery due to pus-like discharge from the wound. Contrast-enhanced CT to find the abscess unexpectedly revealed a pseudoaneurysm in the left retromaxillary area. Massive oral bleeding occurred on the night of re-hospitalization and emergency surgery was done. The bleeding site was identified as a pseudo-aneurysmal rupture of the posterior superior alveolar artery in the retromaxillary area. Hemostasis was achieved by packing Vaseline gauze in the maxillary sinus using an endoscope. Delayed rupture and massive bleeding of posttraumatic retromaxillary pseudoaneurysm after a zygomaticomaxillary fracture is a low-probability, but high-impact event. Therefore, additional contrast-enhanced CT should be considered to evaluate the possibility of a posttraumatic pseudoaneurysm in cases of severe comminuted zygomaticomaxillary fracture.

Contrast-enhanced ultrasonography (CEUS) has been applied to evaluate parenchymal organs in human and veterinary medicine. However, to our knowledge, there is no report on the identification of active bleeding and the bleeding site in veterinary clinical patients. Herein, we describe the use of CEUS in two cases of abdominal bleeding caused by ruptured lesions with malignant abdominal tumors. One dog had a splenic hemangiosarcoma, which had metastasized to the liver; the other dog had hepatic cell carcinomas in the left hepatic lobe, which were lobectomized, and another nodule was identified in the right hepatic lobe. Immediately after the rupture of these oncogenic lesions was suspected, CEUS was performed to identify the bleeding sites. The active bleeding sites were confirmed by hyperechoic pooling signs in the arterial phase, and extravasation could be observed within the defects showing hypoechoic perfusions in the delayed phase of the CEUS. Microbubbles were also observed in the ascites; thus, CEUS could detect the presence of hemorrhage and accurately identify the bleeding site. Collectively, the study findings suggest the usefulness of CEUS in emergent situations as it enables rapid and noninvasive evaluation of bleeding points in case of active bleeding in dogs.

Background: Delayed sternal closure (DSC) is a useful option for patients with intractable bleeding and hemodynamic instability due to prolonged cardiopulmonary bypass and a preoperative bleeding tendency. Vacuum-assisted closure (VAC) has been widely used for sternal wound problems, but only rarely for DSC, and its efficacy for mediastinal drainage immediately after cardiac surgery has not been well established. Therefore, we evaluated the usefulness of DSC using VAC in adult cardiac surgery. Methods: We analyzed 33 patients who underwent DSC using VAC from January 2017 to July 2022. After packing sterile gauze around the heart surface and great vessels, VAC was applied directly without sternal self-retaining retractors and mediastinal drain tubes. Results: Twenty-one patients (63.6%) underwent emergency surgery for conditions including type A acute aortic dissection (n=13), and 8 patients (24.2%) received postoperative extracorporeal membrane oxygenation support. Intractable bleeding (n=25) was the most common reason for an open sternum. The median duration of open sternum was 2 days (interquartile range [25th-75th pertentiles], 2-3.25 days) and 9 patients underwent VAC application more than once. The overall in-hospital mortality rate was 27.3%. Superficial wound problems occurred in 10 patients (30.3%), and there were no deep sternal wound infections. Conclusion: For patients with an open sternum, VAC alone, which is effective for mediastinal drainage and cardiac decompression, had an acceptable superficial wound infection rate and no deep sternal wound infections. In adult cardiac surgery, DSC using VAC may be useful in patients with intractable bleeding or unstable hemodynamics with myocardial edema.

The age of puberty represents a very critical time in the life history of every young woman. The menarche stands as primary indicator of the onset of sexual maturation in females. By late adolescence, 75% of girls experience some problem associated with menstruation. Delayed, irregular, painful, and heavy menstrual bleeding are leading reasons for physician office visits by adolescents, and dysmenorrhea is the leading reason for school absenteeism among girls. This article discusses normal menstrual function during adolescence, then reviews the clinical presentation, evaluation, and management of adolescent dysmenorrhea, dysfunctional uterine bleeding, amenorrhea, and polycystic ovary syndrome.
