연구배경 : 객혈은 임상에서 흔한 증상의 하나인데, 기관지경검사는 객혈에서 진단이나 출혈부위와 확인, 그리고 치료에서 유용하게 사용된다. 그러나 기관지경검사의 적절한 시행시기 및 적응증에 대해서는 논란이 있다. 방법 : 객혈에서 기관지경검사의 적절한 시행시기를 결정하기 위해서, 객혈환자 118명의 의무기록을 후향적으로 분석하여 단순 흉부 X-선 소견, 출혈 양 및 출혈 지속기간과 기관지경검사의 시행시기와의 관계를 알아 보았다. 결과 : 1. 객혈의 원인은 활동성 폐결핵(34명, 28.8%), 비활동성 폐결핵(12명, 10.2%), 기관지확장증(20명, 17.0%), 폐암(9명, 7.6%), 폐국균종(9명, 7.6%), 그리고 기타가 10명(8.5%)이었고, 원인을 알수 없었던 경우가 24명(20.3%)이었다. 2. 출혈병소의 발견율은 기관지경검사를 일찍 시행 할수록 증가하였는데(p<0.05) 기관지경검사를 출혈 도중에 시행한 경우에는 24명의 환자중 21명(87.5%), 지혈된 후 24시간 이내에는 12명중 5명(41.7%), 그 후에 시행한 경우는 82명중 33명(40.2%)에서 출혈병소가 확인되었다. 3. 출혈병소의 발견율은 흉부사진 상 국소적이든 비국소적이든 병변이 보였던 경우에 더 높았다(p<0.05). 단순 흉부 X-선 소견에 관계없이 모든 경우에서 출혈 도중에 기관지경검사를 시행하면 출혈병소의 발견율은 증가하였다(p<0.05). 단순 흉부 X-선상 정상이거나 비국소적인 병변을 보이는 경우에는 출혈 도중이나 지혈 후 48시간 이내에 기관지경검사(조기 기관지경검사)를 시행했을 때 진단율은 증가하였다(p<0.05). 4. 기관지경에 의한 출혈병소의 발견율은 출혈 양이 많을수록 증가하였다(p<0.05). 비슷한 정도의 출혈 양을 보이는 경우에 기관지경검사를 조기에 시행하면 진단율이 증가하는 경향을 보였으나 통계적으로 유의 하지는 않았다(p>0.05). 5. 출혈병소의 발견율은 객혈의 지속기간과는 관계가 없었다(p<0.05). 그러나 객혈의 지속기간이 1주 미만이었던 경우 출혈 도중에 기관지경검사를 했을 때 증가하였다(p<0.05). 객혈의 지속기간이 1주 혹은 그 이상이면 기관지경검사의 시행시기에 따른 발견율의 차이가 없었다(p>0.05). 6. 조기 기관지경검사로 4명의 환자에서 정확한 출혈부위를 확인하여 폐절제술의 수술 부위를 결정하였으며, 1명에서는 기관지경을 통한 트롬빈 주입으로 객혈이 성공적으로 지혈되었다. 결론 : 객혈에서 굴곡성 기관지경검사는 출혈부위를 확인하는데 유용할 뿐만 아니라 치료방침을 결정하는 데에도 도움이 되며, 기관지경검사는 출현도중이나 지혈 후 48시간 이내에 조기에 시행하는 것이 바람직하다.

Postoperative gastrointestinal bleeding is a rare but serious complication that can lead to prolonged hospitalization and significant morbidity and mortality. It can be managed by reoperation, endoscopy, or radiological intervention. Although reoperation carries risks, particularly in critically ill postoperative patients, minimally invasive interventions, such as endoscopy or radiological intervention, confer advantages. Endoscopy allows localization of the bleeding focus and hemostatic management at the same time. Although there have been concerns regarding the potential risk of creating an anastomotic disruption or perforation during early postoperative endoscopy, endoscopic management has become more popular over time. However, there is currently no consensus on the best endoscopic management for postoperative gastrointestinal bleeding because most practices are based on retrospective case series. Furthermore, there is a wide range of individual complexities in anatomical and clinical settings after surgery. This review focused on the safety and effectiveness of endoscopic management in various surgical settings.

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.

Purpose: A life-threatening hemorrhage resulting from a severe facial fracture is rare, but it needs a prompt and aggressive treatment. Especially, a massive oronasal bleeding combined with midfacial fracture which may result from the rupture of the internal maxillary artery. With the recent advances in the radiologic intervention, its use has increased for managing these life threatening case. We reviewed its usefulness with our experiences and literatures. Methods: A retrospective review was performed to determine the usefulness of the transcatheter arterial embolization in patients with panfacial trauma. If the vital signs were unstable, cardiopulmonary resuscitation was performed. Oronasal bleeding was controlled with nasal packing and electrocautery. All injured regions were studied by radiologic study including CT. Even after primary management, if the oronasal bleeding was persistent, radiologic intervention was performed 10 patients were treated with transcatheter arterial embolization and the bleeding focus controlled by embolization with polyvinyl alcohol and gelfoam. Results: After the intervention, the vital signs became stable and there were no complications from embolization in the follow-up for 6 months. Also patients could recover through appropriate operations. Conclusion: Transcatheter arterial embolization for maxillofacial injury has many advantages for both, the doctor and the patient. First, less pain is induced than a compression device or an operation, which is another way to treat oronasal bleeding. Second, it does not need general anesthesia. And through a single procedure not only we can know the accurate bleeding point, but we can also bleeding by embolization.

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.

64세 남성이 2미터 높이에서 낙상한 이후 심한 우측 옆구리 통증으로 내원하였다. 시행한 조영증강 전산화단층촬영에서 우측 혈흉과 다수의 우측 갈비뼈 골절 및 우측 장골의 골절 소견이 있었다. 또한 간 주변에 혈종이 있었으나, 간실질 외상 소견은 보이지 않았다. 먼저 시행된 수술 중, 간문에서 지혈되지 않는 지속적인 출혈이 관찰되었다. 이에 대한 진단을 위해 인터벤션 시술이 시행되었고, 최초 간동맥조영술에서는 출혈 소견이 보이지 않았다. 이어서 시행한 조영증강 전산화단층촬영에서 좌측 복부의 조영제혈관바깥유출이 보였는데, 이는, 경피경간문맥조영술에서 좌측 문맥의 출혈로 확인되었다. 이 지점에 접착제 색전술을 시행했으나, 환자는 끝내 사망하였다. 이 증례를 통해 복부 외상환자 평가에서 간동맥조영술이 정상이라도 간문맥 손상의 가능성을 고려해야 한다는 것과 복부에서도 반충손상기전에 의한 손상이 가능하다는 것을 확인하였다.

Bleeding away a part of the boundary layer next to the wall is an effective method for controlling boundary-layer distortions from incident shock waves or curvature in geometry. When the boundary-layer flow is supersonic, the physics of bleeding with and without an incident shock wave is more complicated than just the removal of lower momentum fluid next to the wall. This paper reviews CFD studies of shock-wave/boundary-layer interactions on a flat plate with bleed into a plenum through a single hole, three holes in tandem, and four rows of staggered holes in which the simulation resolves not just the flow above the plate, but also the flow through each bleed hole and the plenum. The focus is on understanding the nature of the bleed process.

A Morel-Lavallée lesion is a closed degloving injury caused by traumatic separation of the skin and subcutaneous tissue from the underlying fascia. However, since physicians tend to focus on treating the bone fracture, hemodynamic instability accompanying a Morel-Lavallée lesion can sometimes be overlooked. We report the case of a hemodynamically unstable 73-year-old man who had a Morel-Lavallée lesion of the thigh, but no femur fracture. Angiography showed active bleeding from the muscular branch of the right deep femoral artery, which was then successfully embolized.

Abdominal wall hematoma (AWH) after blunt trauma is common, and most cases can be treated conservatively. More invasive treatment is required in patients with traumatic AWH if active bleeding is identified or there is no response to medical treatment. Herein, we report a case of endovascular embolization for traumatic subcutaneous AWH. Almost endovascular treatment for AWH is done through the deep inferior epigastric artery. However, in this case, the superficial inferior epigastric artery was the bleeding focus and embolization target. After understanding the vascular system of the abdominal wall, an endovascular approach and embolization is a safe and effective treatment option for AWH.
