  • Mesenteric ischemic symptoms appear only when two of the three major splanchnic arteries from the abdominal aorta are involved. Recently, we encountered a case of chronic mesenteric ischemia in a 50-year-old female patient caused by atherosclerotic obstruction of the celiac trunk and superior mesenteric artery. She was treated with a retrograde bypass graft from the right common iliac artery to the superior mesenteric artery (SMA) in a C-loop configuration. Complete revascularization is recommended for treatment of intestinal ischemia. When the celiac trunk is a not suitable recipient vessel, bypass grafting to the SMA alone appears to be both an effective and durable procedure for treating intestinal ischemia.

  • Celiac trunk and superior mesenteric artery (SMA) are the main blood supply to the liver and pancreas. The data of anatomical variations in these arteries or their branches are very important clinically and surgically. The aim of this study was to describe the different variants in these arteries through the examination of the angiographs of a large series of Egyptian individuals. This research involved 389 selective angiographies to celiac artery, its branches, and the SMA. Anatomy of the target arteries of people who experienced visceral angiograph was reviewed and the data were recorded. From the total available angiograms in this work, 286 patients (73.52%) had the standard anatomy of celiac trunk and superior mesenteric arteries, and 103 patients (26.47%) had a single or multiple vessel variation. The inferior phrenic artery originates from celiac trunk in 2.05% of patients, while quadrifurcation of the celiac trunk was noticed in only 0.51% of patients. Absence of celiac trunk is also found in 0.51% of patients. Left gastric artery showed an abnormal origin from the splenic artery in 0.51% of patients. Quadrifurcation of common hepatic artery was also noticed. Variant anatomy of the left hepatic artery (LHA) was seen in 9.51% of patients, while variations of the right hepatic artery (RHA) were 14.13%. With the different origin of hepatic arteries, the gastroduodenal artery arose either from the LHA (2.82%), RHA (2.31%) or even from the celiac trunk (1.79%).

  • Superior mesenteric artery aneurysm is the third most common lesion and comprises approximately 5.5 % of all visceral artery aneurysms. The first successful repair was performed by DeBakey and Cooley in 1949. Since then, more than 100 cases have been reported. Fifty to sixty percent of these aneurysms are mycotic in origin. Other less frequent causes include arteriosclerosis, trauma, and medial degeneration. The operations are bypass with autologous tissue or with artificial vascular graft and aneurysmorrhaphy. We have experienced a case of superior mesenteric artery aneurysm which had undergone aneurysmectomy and artificial graft interposition. This is the first domestic case which was successful surgical repaired.

  • 상장간맥동맥 증후군은 일반적인 검사에서 매우 탐지가 어려운 십이지장 만성폐색의 원인으로 대두되고 있다. 그러므로, 십이지장의 횡행부가 상장간막동맥과 복부대동 사이를 지나가기 때문에 복부대동맥과 상장간맥동맥 사이의 각도가 좁아져 십이지장 폐색의 원인을 야기시킨다. 이 각도의 측정은 일반혈관촬영으로는 복잡하고, 종종 부정확한 결과를 초래한다. 또한 한국인을 기준으로 각도 측정에 관한 시도 및 자료가 없는 실정이다. 따라서 본 연구자는 3차원 영상재구성을 위하여 범용컴퓨터에서 실행 가능한 Rapidia S/W를 이용함으로써 복부대동맥으로부터 상장간막동맥기시부의 각도를 측정하였는데, 상장간막동맥증후군이 없는 일반 환자를 대상으로 복부전산화단층촬영의 3차원영상을 이용하였다. 이 실험의 결과 상장간막동맥과 복부대동맥의 평균각도는 $50.05{\pm}15.87^{\circ}$이고 남자의 평균각도는 $53.64{\pm}16.57^{\circ}$이고 여자는 $46.46{\pm}14.98^{\circ}$로 남자의 각도가 약간 더 크게 나타났다. 이러한 연구를 통하여 얻은 각도가 상장간막동맥 증후군의 진단하는데 매우 중요한 지표가 될 것으로 사료된다.

  • 50세 남자 환자가 갑작스런 복통으로 내원하였다. 다중 검출 복부 컴퓨터 단층촬영상 상장간막 동맥의 근위부 폐쇄가 관찰되었다. 입원 당일 응급으로 개복술을 실시하여 혈전제거술을 실시하였고 다음날 다시 혈전제거술과 일부 소장 절제를 하였다 저자들은 상장간막 동맥 폐쇄증을 치험하였기에 보고하는 바이다.

  • 하장간막동맥은 산후출혈의 매우 드문 출혈 혈관이다. 저자들은 질분만 후 하장간막동맥에서 출혈이 있었던 일차성 산후출혈 두 개의 증례를 보고한다. 두 환자 모두 저혈량성 쇼크의 징후를 보이고 있었고, 파종성혈관내응고가 의심되는 상태였다. 산후출혈의 흔한 출혈 혈관인 자궁동맥을 색전한 후에도 출혈은 지속되었다. 하장간막동맥 혈관조영술에서 상직장동맥으로부터 조영제의 혈관외누출이 확인되어 N-butyl cyanoacrylate를 이용한 선택적 색전술을 시행하였다. 이 증례를 통해 산도 손상에 의한 산후출혈이 조절되지 않고 지속될 때 하장간막동맥이 출혈 동맥일 수 있다는 점을 강조하고자 한다.

  • The arterial support of the liver is most commonly from the celiac trunk via the proper hepatic artery (PHA). The PHA divides into left and right branches: the right hepatic artery (RHA) supplies the right and caudate lobes while the left hepatic artery (LHA) supplies the left and quadrate lobes. Aberrant hepatic arteries are relatively common, and the most frequent contributors are the superior mesenteric artery and left gastric artery. Herein we present findings from postmortem dissection of an abdominal cavity that revealed a rare combination of reported variations. Specifically, this subject had three extrahepatic arteries - a replaced LHA (rLHA), a PHA, and a replaced RHA (rRHA). The rLHA originated from the left gastric and the rRHA originated from the superior mesenteric artery. Knowledge of these variations is important for surgical and radiological procedures to avoid complications during treatment and improve patient outcomes.

  • The 26th World Congress of the International Association of Surgeons, Gastroenterologists and Oncologists (IASGO) was held in Seoul, Korea from September 8 to 10, 2016. In this congress, I gave a State-of-the-Art Lecture II entitled "Mesenteric Approach in Pancreatoduodenectomy." The ideal surgery for pancreatic head cancer is isolated pancreatoduodenectomy, which involves en bloc resection using a non-touch isolation technique. My team has been developing isolated pancreatoduodenectomy for pancreatic cancer since 1981, when we developed an antithrombogenic bypass catheter for the portal vein. In this operation, the first and most important step is the use of a mesenteric approach instead of Kocher's maneuver. The mesenteric approach allows dissection from the non-cancer infiltrating side and determination of cancer-free margins and resectability, followed by systematic lymphadenectomy around the superior mesenteric artery. This approach enables early ligation of the inferior pancreatoduodenal artery and total mesopancreas excision. It is the ideal surgery for pancreatic head cancer from both oncological and surgical viewpoints. The precise surgical techniques of the mesenteric approach are herein described.

  • 심장 수술 후 발생한 급성 창자간막 허혈은 사망률이 높은 심각한 합병증이다. 주로 위창자간막 동맥의 폐쇄로 발생하며, 보통 진단이 늦어져 불량한 예후를 가진다. 따라서, 빠른 진단과 적절한 수술적 치료만이 성공적인 결과를 가져올 수 있다. 저자들은 대동맥 판막 치환술 후 급성 창자간막 허혈이 발생한 환자 1예를 성공적으로 치료하였기에 문헌 고찰과 함께 보고하는 바이다.

  • Superior mesenteric artery (SMA) aneurysms are rare and often fatal. A 72-year-old man had previously been admitted to the emergency room with epigastric pain and heart murmur. The echocardiographic diagnosis was vegetation on the aortic and mitral valves, with moderate regurgitation from both valves due to infective endocarditis. No aneurysm was detected on abdominal computed tomography, and emergency double-valve replacement was performed. On postoperative day 25, the patient experienced abrupt abdominal pain, and computed tomography revealed a mycotic SMA aneurysm. Open surgical repair of the SMA aneurysm was performed using the femoral vein, and the patient's postoperative course was uneventful.
