We report a case of celiac artery dissection after abdominal blunt trauma. A 29-year-old man visited the emergency room for acute left periumbilical pain after abdominal blunt trauma from his child. Computed tomography showed a wedge-shaped splenic infarction with splenic artery thrombus. He was hospitalized for careful observation, and after two days, follow-up computed tomographic angiography showed a progressed celiac artery dissection that involved common hepatic artery and an increased extent of splenic infarction. He underwent conventional angiography, and a self-expandable stent was placed between the celiac axis and the common hepatic artery. After two days, follow-up computed tomographic angiography showed good hepatic arterial blood flow via the stent and no progression of splenic infarction. After ten days, he was discharged without complications.

Blunt abdominal trauma may often cause multiple vascular injuries. However, common iliac artery injuries without associated bony injury are very rarely seen in trauma patients. In the present case, a 77-year-old male patient who had no medical history was admitted via the emergency room with blunt abdominal trauma caused by a forklift. At admission, the patient was in shock and had abdominal distension. On abdomino-pelvic computed tomography (CT), the patient was seen to have hemoperitoneum, right common iliac artery thrombosis and left common iliac artery rupture. During surgery, an additional injury to inferior vena cava was confirmed, and a primary repair of the inferior vena cava was successfully performed. However, the bleeding from the left common iliac artery could not be controlled, even with multiple sutures, so the left common iliac artery was ligated. Through an inguinal skin incision, the right common iliac artery thrombosis was removed with a Forgaty catheter and a femoral-to-femoral bypass graft was successfully performed. After the post-operative 13th day, on a follow-up CT angiography, the femoral-to-femoral bypass graft was seen to have good patency, but a right common iliac artery dissection was diagnosed. Thus, a right common iliac artery stent was inserted. Finally, the patient was discharged without complications.

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.

Citri Reticulatae Viride Pericarpium(CRVP) is being used to regulate the flow of Q(氣) However, the mechanism of it's pharmacological actions is not well understood. The purpose of this research was to investigate effects of CRVP contractil response of isolated on abdominal and femoral artery in rabbits and renal artery in pigs. 1. Abdominal artery was relaxed by CRVP in a dose-dependent manner. 2. Femoral artery was relaxed by CRVP in a dose-dependent manner 3. Pretreatment with methylene blue and indomethacin did not inhibited CRVP induced relax in abdominal artery and femoral artery. 4. Renal artery was relaxed by $H_{2}O$ fraction in a dose-dependent manner, 5. Pretreatment with regitine inhibited $H_{2}O$ fraction(CRVP) induced relax in renal artery in a dose-dependent manner. 6. Renal artery was not relaxed by hexane fraction(CRVP) in a dose-dependent manner. 7. Pretreatment with regitine$(10^{-7}M)$ was relaxed by methylene chloride(MC)(CRVP) and $H_{2}O$ fraction in a $0.5{\mu}g/m{\ell}$.

Traumatic iliac vessel injuries constitute approximately 25% of all abdominal vascular injuries. Hospital mortality has been reported at 25~60% and is a result of uncontrolled hemorrhage and hypovolemic shock caused by extensive blood loss. We report the case of a 25-year-old female patient who experienced an external iliac artery injury caused by abdominal minimal stab wound. Traumatic iliac vessel injuries are life-threatening complication of abdominal or pelvic injuries and prompt diagnosis and accurate treatment are important.

Takayasu’s disease produces the occlusive and aneurysmal lesions of major branches of the aorta. Angiography is the most important diagnostic procedure in Takayasu’s disease. Surgical treatment is often justified to avoid the possible lethal consequences of hypertension on the heart, kidney, and brain, as well as in the case of aneurysm because of its risk of rupture. We experienced one case of the Takayasu’s disease associated with abdominal coarctation and renovascular hypertension. The patient was 17 years old female and had suffered from hypertension for 14 months. On physical examination, BP was 150/100 mmHg in the right arm and 120/80 mmHg in the left arm. The pulses of the left brachial and femoral arteries were weakly palpable. Aortogram showed the stenosis of the left common and subclavian arteries, coarctation of the abdominal aorta, and stenosis of the right renal artery and complete occlusion of the left renal artery. The stenosis of the right renal artery and the occlusion of the left renal artery produced the renovascular hypertension. She underwent aorta-aortic bypass for the coarctation of the abdominal aorta and aorta-renal bypass for treatment of renovascular hypertension Postoperatively, both femoral pulses were equally palpable. On discharge, antihypertensive drugs were discontinued. She has remained normotensive for last one year.

The hemodynamic characteristics were compared using commercial CFD code for the stenosed coronary and abdominal arteries. Numerical calculations were carried out in the axisymmetric arteries over the stenotic diameter ratios ranging from 0.25 to 0.875 (6 cases) employing the typical physiological flow conditions. In case of the coronary artery, there was only one recirculation zone observed distal to the stenosis throat during the major portion of the period. However, in case of the abdominal aorta, there were complex recirculation regions found proximal and distal to stenosis throat. For both models, the wall shear stresses(WSS) increased sharply in the converging stenosis, reaching a peak just upstream of the throat, and became negative or low values in the post-stenotic recirculation region. As the results, the oscillatory shear index(OSI) was abruptly increased at the stenosis throat. For the coronary stenosis model, the second peak in the OSI was observed distal to the stenosis. The distance between the first peak and the second peak was increased as the degree of the stenosis was raised. On the orther hand, the abdominal stenosis model showed a complex oscillatory behavior in the OSI index and did not showed such a strong second peak. As the degree of stenosis was increased, recirculation regions of the both arteries were extended much longer and flow pattern became more complex.

SMAS(Superior Mesenteric Artery Syndrome) is a disease caused by a chronic obstruction of the duodenum(transverse portion), which is hardly detectable. However, it is known that when the superior mesenteric artery and abdominal aorta form a narrow angle, that the transverse portion of the duodenum is pressed down between the superior mesenteric artery and the abdominal aorta, and that this can lead to obstruction of the duodenum. Measuring this angle is a complicated job using conventional angiography, and results often turns out to be inaccurate. In addition, no attempt has been made to determine the value of this angle in Koreans. In this study, we conducted abdominal CT angiography using MIP(maximum intensity projection) on patients with no clinical evidence of SMAS in order to determine the angle at which the superior mesenteric artery branches from the abdominal aorta by using PC based software(Rapidia ver. 1.2) for the image reconstruction. Accordingly, we found that the mean angle between the abdominal aorta and the superior mesenteric artery was $50.05{\pm}15.87^{\circ}$ on average, and that the angle in men($53.64{\pm}16.57^{\circ}$) is higher than in women($46.46{\pm}14.98^{\circ}$). We hope that the angles determined by our study will serve as an important indicator for detecting SMAS.

Degenerative vascular disease, previous arterial surgery, long-term ureteral stenting, pelvis surgery, and radiotheraphy are reported as causes of artery-to-collecting-system communication.. Artery-to-collecting-system- communication associated with blunt trauma is rare, but potentially fatal. The diagnosis is very difficult and requires a high degree of suspicion. We were able to make the diagnosis based on the characteristic finding of contrast-enhanced computed tomography (CT) obtained in the early phase, equivalent to the finding obtained in the corticomedullary phase of the kidney. We report a case of artery to collecting system communication due to blunt abdominal trauma following a fall, which was treated by embolization.

Gastric artery bleeding after blunt trauma is rare. In such cases, if vital signs are stable, angiographic embolization may be performed. Although gastric artery embolization is known to be safe due to its anatomical properties, complications may occur. We report a case of gastric necrosis after gastric artery embolization in a patient with blunt abdominal trauma. The 55-year-old male patient was found with gastric arterial bleeding after a traffic accident. His vital signs were stable, and gastric artery embolization was performed. Gastric necrosis was subsequently found, which was treated surgically.
