We experienced one case of surgical treatment of abdominal aortic aneurysm using retroperitoneal approach. The transperitoneal route has been the standard surgical approach for elective and emergency treatment of aneurysmal or occlusive disease. Among its cited advantages for aortic reconstruction are familarity with the exposure, easy access to the infrarenal aorta and iliac vessels, possibility of simultaneous inspection of the intra-abdominal viscera, and speed of opening and closure.Despite the proved versatility of the transperitoneal approach, it is commonly associated with prolonged ileus, increased third space fluid loss, and significant pulmonary complications. The retroperitoneal approach, on the other hand, has many advantages; excellent exposure for the repair of juxtarenal or suprarenal abdominal aortic aneurysms and visceral vessel occlusive disease, fewer postoperative complications, decreased postoperative third-space fluid losses from intraoperative evaporation and ileus, and improved postoperative pulmonary function. Atherosclerosis was most common cause of abdominal aortic aneurysm. Dacron graft[18mm] was replaced successfully.Postoperative course was uneventful and he was discharged in good condition.

기관지 낭종은 기관이나 기관지를 따라 종격동에서 가장 흔하게 나타나는 드문 선천성 기형이며, 특히 뒤쪽 상부 종격동에 생긴다. 기관지 낭종은 다른 위치에서도 발생할 수 있으며 폐, 복강, 그리고 후복강에서 위치가 보고되었다. 저자들은 전천추부 공간에 생긴 후복강 기관지 낭종의 증례를 보고한다. 환자는 수술 후 병리 조직학적 검사에서 최종적으로 진단되었다.

Spinal extradural arachnoid cysts usually cause symptoms related to spinal cord or nerve root compression. Here, we report an atypical presentation of a spinal extradural arachnoid cyst combined with congenital hemivertebra which was presented as a retroperitoneal mass that exerted mass effects to the abdominal organs. On image studies, the communication between the cystic pedicle and the spinal arachnoid space was indistinct. Based on our experience and the literature of the pathogenesis, we planned anterior approach for removal of the arachnoid cyst in order to focus on mass removal rather than ligation of the fistulous channel. In our estimation this was feasible considering radiologic findings and also essential for the symptom relief. The cyst was totally removed with the clogged 'thecal sac-side' end of the cystic pedicle. The patient was free of abdominal discomfort by one month after the surgery.

횡격막하 후복막강에 발생한 폐격리증은 매우 드문 선천성 기형으로 증상없이 우연히 발견되는 경우가 많으며 호발부위 위치상 다른 부신옆 종양들과 감별을 요하며 외과적 절제술로 치료된다. 저자들은 국내에서 아직 보고되지 않은 횡격막하 후복막강 폐격리증을 1례 경험하였기에 보고하는 바이다.

기관지성 낭종은 일반적으로 폐실질 내 혹은 종격동 내에 발생하는 것으로 알려져 있다. 종격동 내에 위치하는 경우 기관지와 식도 부근에 위치하나 후복막강에 위치하는 경우는 매우 드물다. 수술 전에 기관지성 낭종과 양성 낭종을 구분하는 것은 매우 어렵다. 저자들은 수술 전 양성 신경종으로 진단후 좌측 개흉술을 통해 절제된 후복막강의 종괴가 병리조직검사 결과 기관지성 낭종으로 밝혀져 보고하는 바이다.

Objective: To assess the safety and efficacy of lymphopseudoaneurysm (LPA) glue (n-butyl cyanoacrylate [NBCA]) embolization in the management of chylous ascites after retroperitoneal surgery. Materials and Methods: A retrospective analysis from January 2014 to October 2018 was performed in six patients (4 females and 2 males; mean age, 45.3 ± 14.2 years; range, 26-61 years) who underwent LPA embolization for chylous ascites developing after retroperitoneal surgery involving the perirenal space (four donor nephrectomies, one partial nephrectomy, and one retroperitoneal lymphadenectomy). After placing a percutaneous drainage catheter into the LPA or adjacent lymphocele, embolization was performed by filling the LPA itself with a mixture of glue and Lipiodol (Guerbet). Results: Daily drainage from percutaneously placed drains exceeded 300 mL/day despite medical and surgical treatment (volume: mean, 1173 ± 1098 mL; range, 305-2800 mL). Intranodal lymphangiography was performed in four of the six patients and revealed leakage in 2 patients. Percutaneous embolization of the LPA was successful in all patients using an NBCA and Lipiodol mixture in a ratio of 1:1-1:2 (volume: mean, 4.3 ± 1.1 mL; range, 3-6 mL). Chylous ascites was resolved and the drainage catheter was removed in all patients within 4 days after the procedure (mean, 2.0 ± 1.8 days; range, 0-4 days). No procedure-related complications or recurrence of chylous ascites occurred during a mean follow-up period of 37.3 months (range, 21.1-48.4 months). Conclusion: Glue embolization of LPA has the potential to be a feasible and effective treatment method for the management of chylous ascites after retroperitoneal surgery.

Retroperitoneal hematoma (RH) due to radiologic intervention for an intracranial lesion is relatively rare, difficult to diagnose, and can be lifethreatening. We report a case of RH that developed in a patient on anticoagulant therapy following endovascular coiling of a ruptured anterior communicating artery (AcoA) aneurysm. An 82-year-old man presented with a 12-day history of headache. Computed tomography (CT) on admission demonstrated slight subarachnoid hemorrhage, and left carotid angiography revealed an AcoA aneurysm. The next day, the aneurysm was occluded with coils via the femoral approach under general anesthesia. The patient received a bolus of 5,000 units of heparin immediately following the procedure, and an infusion rate of 10,000 units/day was initiated. The patient gradually became hypotensive 25 hours after coiling. Abdominal CT showed a huge, high-density soft-tissue mass filling the right side of the retroperitoneum space. The patient eventually died of multiple organ failure five days after coiling. RH after interventional radiology for neurological disease is relatively rare and can be difficult to diagnose if consciousness is disturbed. This case demonstrates the importance of performing routine physical examinations, sequentially measuring the hematocrit and closely monitoring systemic blood pressures following interventional radiologic procedures in patients with abnormal mental status.

Immunoglobulin G4 (이하 IgG4)연관 질환은 풍부한 IgG4 형질세포 형태의 림프형질 세포 침윤과 현저한 섬유아세포 증식을 특징으로 하는 전신 질환이다. 일반적으로 IgG4 연관 질환의 후복막강 발현은 복부 대동맥을 둘러싸거나, 요관을 압박하여 수신증을 일으키는 연조직의 형태로 나타난다. 우리는 75세 여성 환자에서 발생한 비전형적인 IgG4 연관 질환의 후복막강 발현에 대해 보고하고자 한다. 수술 전 전산화단층촬영에서 정상 해부학적 경계를 넘어서는 침윤성 성질을 가진 불규칙한 형태의 후복막강의 종괴가 관찰되었으며, 이는 악성 혹은 염증성 상태가 의심되었다. 조영증강 촬영에서 종괴는 균일한 점진적인 조영증강을 보였다.

후복막 낭성 림프관종은 양성종양으로 매우 드문 질환이다. 수술적 절제가 원칙이나, 경화요법을 우선적으로 고려할 수도 있다. 9세 남자가 병원 방문 4일 전부터점점 심해지는 복통을 주소로 입원하였다. 혈색소 농도가 입원 당일 12.8 g/dL에서, 입원 3병일째 10.6 g/dL로 감소한 소견이 있었다. 복부 전산화 단층촬영에서 크고 종양내부에 격막이 있는 분엽상의 후복막 낭종($10{\times}9.5{\times}5cm$) 한 개가 좌측 신장 주위 공간에서 관찰되었다. 종양 내부에는 출혈이 동반되어 있었으며, 하장간막정맥이 종양에 의해 둘러싸여져 있었다. 수술적 치료의 위험도가 매우 높을 것으로 판단되어 낭종조영술을 시행하였고, 경피적 도관 배액술과 에탄올 경화요법을 시행하였다. 추적 검사로 시행한 복부 전산화 단층촬영에서 종양의 크기가 현저히 감소된 소견을 보였다. 환자는 퇴원 후 13개월 째 현재까지 낭종의 재발없이 건강하게 지내고 있다. 결론적으로, 수술적 치료의 위험이 높은 후복막 낭성 림프관종이 있는 경우 경피적 도관 배액술과 경화요법을 우선적으로 고려해야 할 것이다.

There are many possible causes of duodenal obstruction, such as congenital anomalies and various acquired conditions associated with space-occupying lesions. However, hemorrhage or retroperitoneal hematoma is a rare cause of duodenal obstruction. Here, we report the case of a 55-year-old man who developed duodenal obstruction due to a large retroperitoneal hematoma after acupuncture therapy. The patient experienced abdominal discomfort along with vomiting and nausea. Considering the size of the hematoma, emergency surgery could have been performed, but conservative treatment was continued because the patient's vital signs were stable. With spontaneous resolution of the hematoma, the symptoms of duodenal obstruction improved. The patient was eventually discharged without any complications associated with the hematoma. Our findings suggest that even when a hematoma is large, a conservative approach can be maintained until improvement of the symptoms of duodenal obstruction if the vital signs of the patient remain stable.
