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%).

Objective: To determine the incidence and etiologies of celiac axis stenosis in asymptomatic individuals. Materials and Methods: This prospective study involved 400 consecutive patients (male: 319, female: 81) referred to us for celiac arteriography between April and July 1999. When celiac axis branches were opacified by collateral circulation during superior mesenteric arteriography, the presence of celiac axis stenosis was suspected; lateral projection celiac arteriography was performed and the pressure gradient was measured. The indicators used to determine whether or not celiac axis stenosis was significant were luminal narrowing of more than 50% and a resultant pressure gradient of at least 10 mmHg. Its etiology was determined on the basis of angiographic appearances and CT findings. Results: Twenty-nine patients (7.3%) had celiac axis stenosis. The etiology of the condition was extrinsic compression due to the median arcuate ligament in 16 patients (55%) and atherosclerosis in three (10%), while in ten (35%) it was not determined. The incidence of celiac axis stenosis did not vary significantly according to sex, age and the presence of calcified aortic plaque representing atherosclerosis. Conclusion: The incidence of hemodynamically significant celiac axis stenosis in this asymptomatic Korean population was 7.3% and the most important etiology was extrinsic compression by the median arcuate ligament of the diaphragm. Atherosclerosis was only a minor cause of the condition.

A rare case of aneurysm of the celiac artery due to arteriosclerosis was presented. The patient was 56-year-old female and had suffered from hypertension for 4 years, and recently, from dyspepsia prior to admission for 2 months. The operation was operated upon by interposition of an autogenous tubular saphenous vein graft between the proximal celiac artery and the common opening of the hepatic and the splenic arteries in the opened aneurysmal sac with inclusion technique. The postoperative course was uneventful.

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.

Backgroud: We have performed the CT-guided celiac plexus block (CPB) using anterior approach to evaluate the safety and efficacy of the procedure and to determine the role of CT. Methods: CPB were done in 10 patients (5 men and 5 women: mean age, 58.1 years) with intractable upper abdominal pain due to terminal malignancy of the stomach (n=3), pancreas (n=4), gallbladder (n=2), and liver (n=1). To permit an anterior approach, patients lay supine on the CT scan table during the procedure. One 21-guage Chiba needle was placed just anterior to the diaphragmatic crus between the celiac and superior mesenteric arteries and 10~12 ml of dehydrated alcohol was injected. Degree of pain relief following the procedure was assessed and pain was graded on a numeric rating scale (NRS) from 0 to 10. Results: The results suggest a direct relation between the degree of celiac invasion and the response to the CPB. With CT guidance, it is possible for us to direct the needle into more accurate region, allowing alcohol to be deposited in specific ganglion area. Conclusions: CT-guided CPB using an anterior approach was an easy and effective way of reducing intractable upper abdominal pain due to terminal malignancies. CT-guidance allowed precise needle placement and safe procedure. Careful classification of cases is important to predict the degree of pain relief using the grading system based on the degree of involvement of the celiac plexus.

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.

Background: Due to the concern of flow competition or retrograde steal, it has been generally suggested that the right gastroepiploic artery(RGEA) pedicled graft should be used in critical coronary stenosis lesion. The study was designed to evaluate the potential of retrograde flow competition in the RGEA pedicled graft by measuring the native pressure differences(PD) between the normal coronary artery and celiac arterial pressure, which would be compared with trans-stenosis pressure gradients(TSPG) in coronary artery occlusive disease. Material and Method: Between July, 1998 and February, 1999, pressures of the right coronary artery and the right gastroepiploic artery(or the celiac artery) were measured in patients with the patent right coronary artery(n=12). The PD between the arteries was compared with the TSPG in the occlusive coronary arteries(n=32). Result: The pressures of the normal right coronary artery and celiac artery were 143$\pm$23 vs. 134$\pm$17mmHg in systole(p<0.005), 74$\pm$13 vs. 73$\pm$14mmHg in diastole(p=NS), and 100$\pm$16 vs. 97$\pm$15mmHg in mean (p<0.05). The PD between the arteries were -8~25mmHg in systole, -4~7mmHg in diastole, and -1~10mmHg in mean. The TSPG measured in the occlusive coronary arteries were -4~19(7$\pm$5.8)mmHg in the lesion less than 75% stenosis vs. 7~74(27$\pm$18.3)mmHg in the 75% or over stenosis lesion(p<0.005). The normally existing pressure difference between the coronary arteries and RGEA(15~20mmHg) was significantlyless than the TSPG in .the occlusive coronary artery with 75% or over stenosis(p<0.001). Conclusion: If the pressure gradient between the RGEA and the coronary artery distal to the stenosis is the main determinant of development of retrograde flow competiton in the RGEA pedicled graft, the above data suggests that there will be little chance of competition when It is used in the coronary lesion with 75% or over stenosis.

Anticipating a wide range of morphological variations of arterial anatomy of foregut derivatives beyond the classical pattern, a precise understanding is pertinent to preoperative diagnosis, operative procedure and to avoid potentially devastating post-operative outcome during various traumatic and non-traumatic vascular insult of foregut. The study aimed to revisit the morphological details and update unusual configurations of arteries of foregut to establish clinico-anatomical correlations. This study described the detailed branching pattern of coeliac trunk (CT) as principal artery of foregut with source & course of hepatic, gastric, duodenal and pancreatic branches in 58 cadaveric dissections. Based on morphology, different types and subtypes were made. The descriptions were explained using figures and pertinent tables. Among classical branches of CT, splenic artery was found as most stable whereas other two branches were found to be most variable with missing common hepatic artery in 11 cases. In addition to classical trifurcation (65.52%), different types of bifurcation (12.07%) and tetrafurcations (22.41%) of CT were observed. Regarding variations of hepatic arteries (27.59%), both non-classical origin and accessory hepatic branches were found. In case of gastric branches, more variant origins were seen with right gastric (50%) as compared to left gastric artery (34.48%). Other morphological variations included non-classical origin of gastro-duodenal artery (18.96%) along with presence of accessory pancreatic (17.13%) and duodenal arteries (6.38%). Awareness of anatomical variations regarding circulatory dynamics of foregut is worth knowing in order to facilitate successful planning of surgery involving upper abdominal organs with least complications.

Neurofibromatosis type I is an autosomal dominant disorder with varied manifestations in bone, soft tissue, the nervous system and skin. This is characterized by cafe-au-lait spots, neurofibromas, Lisch nodules, optic glioma, bony displasia, and intertriginous freckling. One of the more serious aspect of the disease relates to the arterial involvement. Vascular changes in neurofibromatosis may occur in any arterial tree from the proximal aorta to the small arteries but these changes are most common in the renal arteries, aorta, celiac arteries and mesenteric arteries. Of the many complications observed in neurofibromatosis type I, cerebrovascular lesions may be the least appreciated. About 40 cases of neurofibromatosis type I associated with occlusive cerebrovascular disorders have been reported in the literature, but MRI and angiographic findings typical of moyamoya disease are rarely described. We experienced a case of moyamoya disease associated with neurofibromatosis type I in a 3-year-old girl who of complained gait disturbance and paraparesis and showed findings typical of moyamoya disease on MRI and carotid angiogram.
