배경: 외상성 대동맥 파열은 사망률이 매우 높은 치명적인 손상이며, 환자의 경과는 동반된 손상과 밀접한 관계가 있다. 따라서 적절한 수술 시기와 치료 방침을 결정하는 것이 중요하다. 대상 및 방법: 겸자 봉합술로 수술한 15명의 외상성 흉부 하행 대동맥 파열 환자를 대상으로 동반 손상 여부, 수술 후 경과 등을 후향적으로 분석하였다. 결과: 사망률은 6.68% (1예)로 환자는 수술 중 사망하였으며, 지연 혈복강으로 인한 것으로 생각한다. 평균 수술 시간 및 대동맥 겸자 시간은 $231{\pm}53.1$분, $13.1{\pm}5.3$분이었다. 1예에서 수술 후 10일째, 장 폐쇄 증상을 호소하여 시행한 복부 전산화 단층 촬영에서 기계적 장 폐쇄가 발견되어 구획 절제술을 시행하였다. 결론: 외상성 대동맥 파열은 여러 방법으로 수술할 수 있지만, 그중 겸자 봉합술은 비교적 안전하고 효과적인 방법이라고 생각한다.

외상성 흉부 대동맥 파열에 의한 가성대동맥류에 대한 일반적인 치료 방법은 수술이다. 그러나 환자의 전신상태가 개흉술을 통한 수술 또는 체외순환보조를 통한 수술을 시행 받기 어려운 경우에는 다른 치료 방법을 선택해야 한다. 저자들은 두부, 복부, 골반의 광범위한 다발성 손상이 동반되어 수술적 치료를 시행하기 어려웠던 대동맥파열에 의한 가성대동맥류 환자에 대하여 중재적 시술을 통해 스텐트-그라프트를 삽입하여 치료한 1예를 문헌 고찰과 함께 보고하는 바이다.

Traumatic abdominal wall hernia is a rare presentation, most commonly reported in the context of motor vehicle accidents and associated with blunt abdominal injuries and handlebar injuries in the pediatric population. A 13-year-old boy presented with multiple traumatic injuries and hemodynamic instability after a high-speed motor vehicle accident. His injuries consisted of massive traumatic abdominal wall hernia (grade 4) with bowel injury and perforation, blunt aortic injury, a Chance fracture, hemopneumothorax, and a humeral shaft fracture. Initial surgical management included partial resection of the terminal ileum, sigmoid colon, and descending colon. Laparostomy was managed with negative pressure wound therapy. The patient underwent skin-only primary closure of the abdominal wall and required multiple returns to theatre for debridement, dressing changes, and repair of other injuries. Various surgical management options for abdominal wall closure were considered. In total, he underwent 36 procedures. The multiple injuries had competing management aims, which required close collaboration between specialist clinicians to form an individualized management plan. The severity and complexity of this injury was of a scale not previously experienced by many clinicians and benefited from intrahospital and interhospital specialist collaboration. The ideal aim of primary surgical repair was not possible in this case of a giant abdominal wall defect.

Background: Paraplegia is a devastating complication following operations on the thoracoabdominal aorta. We investigated whether histidine-tryptophan-ketoglutarate (HTK) solution could reduce the extent of ischemia/reperfusion (IR) spinal cord injuries in a rat model using a direct delivery method. Methods: Twenty-four Sprague-Dawley male rats were randomly divided into four groups. The sham group (n=6) underwent a sham operation, the IR group (n=6) underwent only an aortic occlusion, the saline infusion group (saline group, n=6) underwent an aortic occlusion and direct infusion of cold saline into the occluded aortic segment, and the HTK infusion group (HTK group, n=6) underwent an aortic occlusion and direct infusion of cold HTK solution into the occluded aortic segment. An IR spinal cord injury was induced by transabdominal clamping of the aorta distally to the left renal artery and proximally to the aortic bifurcation for 60 minutes. A neurological evaluation of locomotor function was performed using the modified Tarlov score after 48 hours of reperfusion. The spinal cord was harvested for histopathological and immunohistochemical examinations. Results: The spinal cord IR model using direct drug delivery in rats was highly reproducible. The Tarlov score was 4.0 in the sham group, $1.17{\pm}0.75$ in the IR group, $1.33{\pm}1.03$ in the saline group, and $2.67{\pm}0.81$ in the HTK group (p=0.04). The histopathological analysis of the HTK group showed reduced neuronal cell death. Conclusion: Direct infusion of cold HTK solution into the occluded aortic segment may reduce the extent of spinal cord injuries in an IR model in rats.

2-D echocardiographic examination of the aortic root diameter was known to be useful in the selection of the size of the prosthetic valve. Valve-patient mismatch was occasionally a serious problem after valve replacement, especially in aortic valve disease. Preoperative knowledge of the patient`s valve annulus size is therefore of great importance in the surgical management of these patients. So the relationship between preoperative 2-D echocardiographic diameter of the annulus size and replaced prosthetic valve were evaluated. 13 patients were analyzed in this study. 2-D echocardiographic measurements of aortic annulus diameter, as determined from the parasternal long axis view and apical four chamber view, demonstrated a high correlation with actual prosthetic valve size implanted at surgery[r=0.86, p< 0.001, SEE=1.08].

We have recently experienced a rare case of abdominal aortic injury caused by deceleration force during fall in upright position. The patient was 43-year-old brick-layer fell from 12 meter height and sustained compression fracture of the spine and both legs. The aortic injury was unnoticed at that time. About 2 years later, marked stenosis of the distal abdominal aorta was found together with clinical manifestations of ischemia of both legs. Aorto-femoral bypass on both sides has completely relieved the symptoms, Similar type of abdominal aortic injuries could not be found in the literatures.

A 27-year-old man was admitted with a penetrating injury at the mid-manubrium. Computed tomographic (CT) angiography showed a f illing def ect in the aortic arch. This was evaluated as a sign of injury and the patient underwent an emergency operation. No active bleeding or clot was f ound in the mediastinum during the operation. The laceration point was between the innominate and the left carotid artery posteriorly. The injury was approached using hypothermic circulatory arrest. Aortotomy and exploration showed a 2-cm-long full-thickness aortic injury with an overlying clot. A filling defect on angiography as a sign of a penetrating arch injury has never been reported previously, but was the main pathological finding on CT angiography in our case. The aorta is a high-pressure system and injuries to it should be treated aggressively.

Aortic dissection caused by blunt trauma is a rare injury that can be complicated by malperfusion syndrome resulting from obstruction of branch vessels of the aorta. Here, we present a case of traumatic type B aortic dissection with right renal and small bowel ischemia, successfully managed by endovascular fenestration.

Major bleeding caused by vascular injuries of the abdominal aorta or its branches after blunt trauma often leads to mortality or major morbidity. We report a case that lumbar artery injury following blunt trauma was spontaneously resolved without any surgical or interventional treatment. Lumbar artery injury after blunt trauma could be treated conservatively without surgical or interventional treatment in a selected case. When an aortic or its branch injury was suspicious, diagnostic angiograms in the setting of interventional treatment may be helpful to decide an appropriate treatment modality.

흉부 대동맥의 외상성 파열은 두부 손상 다음으로 흔한 교통사고의 사망원인으로 약 85%의 환자가 병원 도착 전에 사망한다. 가장 흔한 기전은 고속의 차량이 충돌 등으로 인한 급작스런 감속에 의해 발생되며 대동맥 협부가 전체 대동맥 손상의 95%에 해당된다. 또 다른 기전으로는 흉부 압박 손상에 의해 골절되어 전위된 흉골병과 흉부 척추 사이에 대동맥이 끼이면서 나타날 수 있는데 이로 인해 흔하지 않은 위치의 대동맥벽의 내막이 파열된다. 저자들은 감속사고가 아닌 흉부 압박에 의해 대동맥궁이 파열되어 박리된 증례에 대해 집중적인 내과 치료 후에 지연 수술로 완전 순환정지 하에 뇌보호를 시행하면서 상행 대동맥의 일부와 대동맥궁을 인조혈관으로 치환하였기에 보고하는 바이다.
