Celiac artery stenting: a new strategy for patients with pancreaticoduodenal artery aneurysm associated with stenosis of the celiac artery.

We report a new strategy--celiac artery stenting--to relieve stenosis of the celiac arterial root. This was performed in two patients with pancreaticoduodenal artery (PDA) aneurysm associated with a stenotic celiac arterial root. The first patient was a 66-year-old man complaining of abrupt onset of upper abdominal pain. Abdominal computed tomography revealed a huge retroperitoneal hematoma behind the duodenum, and superior mesenteric artery (SMA) angiography demonstrated an aneurysm arising from inferior pancreaticoduodenal artery and celiac arteriography showed a stenotic celiac arterial root. Transcatheter embolization of the aneurysm was tried, but failed. Because of his unstable hemodynamics, emergent laparotomy with resection of the aneurysm was performed. Fourteen days after the operation, percutaneous transluminal angioplasty with celiac arterial stenting was done. The patient was discharged 2 days later, and has had no further bleeding episode for 3 years. The second patient was a 46-year-old woman, who also complained of acute upper abdominal pain. Abdominal computed tomography disclosed a huge retroperitoneal hematoma, and selective SMA angiography demonstrated an aneurysm arising from the inferior pancreaticoduodenal artery, and celiac arteriography showed a stenotic celiac arterial root. Because angiography showed no active bleeding from the aneurysm, percutaneous transluminal angioplastic stenting of the stenotic celiac artery was performed. She was discharged 5 days later and has had no further bleeding episode for 2 years. Celiac arterial stenting, as shown in our two patients, could be easily and safely employed in patients with PDA aneurysm associated with a stenotic celiac arterial root to release the stenosis of the celiac arterial root and to prevent further possible bleeding.

Bleeding gastric varices as a result of splenic vein compression by a celiac arterial aneurysm.

Celiac arterial aneurysms are very unusual and often lack clinical manifestations. According to our review of the literature, this is the first report of a patient with a large celiac arterial aneurysm who exhibited hematemesis from gastric varices. Arteriography, as well as color Doppler ultrasonography and enhanced computed tomography, contributed to the diagnosis of this aneurysm, which was best exposed by a left thoracoabdominal approach. In this patient the lesion was a false aneurysm with perforation of the celiac artery, so simple closure of the orifice was carried out and the revascularization of the celiac artery was not necessary, but we should take care not to ignore the possible recurrence of vascular lesions. The risk of celiac arterial aneurysm rupture is relatively high, but the operative mortality of unruptured aneurysms is now so low that operation is strongly recommended for all patients with this type of aneurysm.

[Rupture of operated celiac artery aneurysm].

Celiac artery aneurysm is a rare and its rupture is the most frequent and serious complication. The patient who underwent aneurysmectomy and aorto - celiac artery synthetic prosthesis graft interposition in another cardiovascular surgery center two years ago, was admitted to our department with complaints of fever and abdominal discomfort. Computed tomography revealed an aneurysm with 1 cm of diameter at the beginning of celiac artery and intraperitoneal hemorrhage. Acute hematocrit descent was occurred and then cardiac arrest was taken place. So, emergency thoracotomy was done. Aorta was compressed with hand and at the same time internal cardiac resuscitation was done then cross clamp was placed onto aorta. Median abdominal incision was done and ruptured celiac artery aneurysm was observed. Infected graft was removed and PTFE graft was interposed from descending aorta to a. hepatica propria, away from the infected area. During 17 months of follow-up period graft no complication was observed. We believe that because of its rarity, tendency to be asymptomatic along with high incidence of rupture, celiac artery aneurysms should not be underestimated.

Celiac artery aneurysm associated with atherosclerotic common hepatic artery stenosis.

Celiac artery aneurysms are rare vascular lesions and represent 4% of all splanchnic aneurysms. Media degeneration and atherosclerosis are the most common underlying etiologic factors. The risk of rupture and the associated mortality rate are 13% and 40% respectively. In contrast, elective repair carries a low mortality rate of 5%. Most of celiac artery aneurysms are asymptomatic and in the past nearly 80% of the cases were diagnosed when ruptured. Recently, there is an increased recognition of all splanchnic aneurysm types, probably because of better diagnostic techniques. We report a case of celiac artery aneurysm with severe atherosclerotic stenosis of the common hepatic artery. We performed, through a midline supraumbilical laparotomy, extended partial aneurysmectomy and common hepatic artery ostium endarterectomy. For the closure we used Dacron patch. The uncomplicated postoperative patient's course, with no evidence of liver dysfunction and excellent patency of the common hepatic artery, suggests that this technique offered good results and minimized the perioperative risk.

Differential effect of nitric oxide synthase inhibitors on acetylcholine-induced relaxation of rat pulmonary and celiac artery rings.

The effect of NG-monomethyl-L-arginine (L-NMMA) and N omega-nitro-L-arginine methyl ester (L-NAME) on acetylcholine (ACh) induced relaxation of rat intrapulmonary artery and celiac artery ring segments was studied in vitro with and without meclofenamate pretreatment. L-NMMA, and to a lesser extent L-NAME, raised baseline tone more in pulmonary than celiac arteries. Pretreatment of pulmonary and celiac artery rings with meclofenamate did not alter this contractile effect. Pulmonary artery and celiac artery ring segments were precontracted with phenylephrine, and cumulative concentration-relaxation curves to ACh were obtained before and after incubation of the rings with L-NAME or L-NMMA. L-NAME inhibited the ACh-induced relaxation of pulmonary arterial rings at 10000 fold lower concentrations than those needed to only partly inhibit the ACh-induced relaxation of celiac artery rings. L-NMMA (10-300 microM) inhibited the ACh-induced relaxation of pulmonary arterial rings in a concentration-dependent manner, whereas L-NMMA (300 microM) only partially inhibited the ACh-induced relaxation of celiac artery rings. The inhibition of ACh-induced relaxation by L-NAME and to a lesser extent by L-NMMA was more when pulmonary and celiac artery rings were pretreated with meclofenamate (1.0 microM). These results suggest that in the pulmonary artery nitric oxide plays a greater role in the modulation of baseline vascular tone and ACh-induced relaxation than in the celiac artery. In addition, cyclooxygenase products do not contribute to the direct contractile responses to L-NAME and L-NMMA in both the pulmonary and celiac artery rings but do modulate the ACh-induced relaxation of these vessels.

[Intralobar pulmonary sequestration with an aberrant artery originating from the celiac artery and communicating with the pulmonary artery].

A 13-year-old boy underwent a right lower lobectomy for removal of an intralobar pulmonary sequestrum with a very rare type of aberrant artery. The aberrant artery originated from the celiac artery and communicated with the pulmonary artery. Angiographic and histologic findings led us to the following hypothesis regarding the origin of the sequestrum in this patient: There was a hypoplastic bronchus and an aberrant artery that originated from the celiac artery. Infection caused obstruction of the hypoplastic bronchus, which resulted in formation of the sequestrum. Another possibility is that high systemic pressure in the aberrant artery caused destruction of alveoli and led to the formation of cysts in the lung and to sequestration. Finally, the aberrant artery and the pulmonary artery communicated due to chronic inflammation in the sequestrum.

Coil embolization of an inferior pancreaticoduodenal artery aneurysm associated with celiac artery occlusion.

Pancreaticoduodenal arcade aneurysms are rare. Untreated, these lesions enlarge progressively and have the potential for spontaneous rupture. Aneurysmal degeneration of pancreaticoduodenal arcade vessels is known to be associated with celiac artery occlusion, vasculitis, and certain connective tissue disorders. Given their precarious location, surgical expiration is a challenging endeavor. Innovations in endovascular techniques offer a possible alternative. We report a case of a 55-year-old gentleman with a 2.2x2.1-cm aneurysm of one of the inferior pancreaticoduodenal arteries and a concomitant finding of occlusion of the celiac artery trunk. Percutaneous coil embolization of the aneurysm was employed as the treatment in this case with the successful exclusion of the aneurysm sac, while maintaining continuity of the native circulation. This case report demonstrates that, due to the success rate of aneurysm exclusion and the relatively low morbidity and mortality rates seen with endovascular repair as compared to surgical intervention, endovascular treatment has become the treatment of choice for pancreaticoduodenal artery aneurysms.

Chemoembolization for hepatocellular carcinoma via the inferior pancreaticoduodenal artery in patients with celiac artery stenosis.

Twenty-one patients with hepatocellular carcinoma (HCC) accompanied by extensive celiac artery stenosis or obstruction were treated by chemoembolization via the inferior pancreaticoduodenal artery (IPDA). The tip of the catheter was placed in the arteries in front of the confluence with the proper hepatic artery in 12 patients (group A: the proximal portion of the IPDA in 10, and common hepatic artery in 2), and in the proper hepatic artery or branches of it (group B) in 9 using a coaxial catheter system. Transient hyperamylasemia was observed in 10 of the 12 patients in group A and in 3 of the 9 patients in group B after chemoembolization. Splenic infarction developed in 8 patients in group A and in none in group B. Intrapancreatic fluid collection was present in 2 patients in group A following chemoembolization. No fatal complications were encountered. The 1-, 2-, and 3-year survival rates of the 10 patients in group A treated by only chemoembolization were 90, 57, and 23%, respectively (mean survival 780 days). The 1- and 2-year survival rates of 9 patients in group B were 85.8 and 85.8% (mean 879 days), respectively. Considering the severity of complications and the survival rates in groups A and B, chemoembolization by superselective catheterization into the hepatic artery via the IPDA is the treatment of choice. However, chemoembolization from the arteries in front of the confluence with the proper hepatic artery seems to be acceptable in cases of hypervascular HCC which fail to be superselectively catheterized.

Celiac artery compression syndrome.

Celiac artery compression syndrome occurs when the median arcuate ligament of the diaphragm causes extrinsic compression of the celiac trunk. We report a case of a 65-year-old woman who presented with a three-month history of postprandial abdominal pain, nausea and some emesis, without weight loss. There was a bruit in the upper mid-epigastrium and the lateral aortic arteriography revealed a significant stenosis of the celiac artery. At operation, the celiac axis was found to be severely compressed anteriorly by fibers forming the inferior margin of the arcuate ligament of the diaphragm. The ligament was cut and a vein by-pass from the supraceliac aorta to the distal celiac artery was performed. The patient remains well and free of symptoms two and a half years since operation.In this report we discuss the indications and the therapeutic options of this syndrome as well as a review of the literature is being given.

[A case report of intralobar pulmonary sequestration with an anomalous artery originating from the celiac artery].

A 43-year-old female was admitted to our hospital because of an abnormality detected in chest radiography. Chest radiographs showed a nodular shadow behind the heart. Chest CT revealed a nodule connected to the descending aorta with increased blood flow in left lower lobe, suggesting the presence of a pulmonary sequestration. Bronchography showed an intralobar sequestrated lung in the left lower lobe. Aortography demonstrated that the sequestrated lung was fed by an anomalous artery 20 mm in diameter, originating from the celiac artery. From those findings, Pryce type IIintralobar pulmonary sequestration was diagnosed, and the left lower lobe was removed. Histological findings from the excised tissues showed mild dilatation of the bronchioles and hypervascularity.

Surgical treatment of superior mesenteric artery dissecting aneurysm and simultaneous celiac artery compression.

Spontaneous dissections of visceral arteries are rare, but when they do occur, they most commonly involve the superior mesenteric artery (SMA). We present a case of intestinal ischemia caused by a spontaneous dissection of the SMA in a patient with simultaneous celiac artery occlusion. The patient was a 45-year-old woman who presented with intestinal angina of sudden onset. Arteriography revealed the classic findings of SMA dissection and occlusion of the celiac artery. The patient underwent repair of both visceral vessels and made a full recovery. The 18 previously reported cases of isolated, spontaneous dissection of the SMA are reviewed. No previous case has been associated with celiac compression syndrome. The reported experience with symptomatic dissections of the SMA would suggest that prompt surgical repair is indicated and yields excellent results.

[Celiac artery aneurysm: urgent surgical case report].

Visceral artery aneurysm account for up to 5-10% of overall artery aneurysm. Celiac artery aneurysm are reported in 4% of these patients. The most common etiologic findings are atherosclerosis and tunica media infective degeneration. The radiological imaging led to more accurate morphological and anatomical definitions of this pathology and improved elective and urgent surgical treatment of selected patients. The Authors report a case of celiac artery aneurysm.

Celiac artery compression syndrome.

Celiac artery compression syndrome has been referred to in the literature as an entity in limbo, yet there have been many cases that have been well documented. This report describes two cases of abdominal pain with epigastric bruits in which the diagnosis of celiac artery stenosis was made. The abdominal bruit with its diastolic component had been the "tip-off" in both of these patients. Both patients did poorly with conservative treatment and eventually required surgical decompression.

Anatomical variants of the celiac artery in the sheep, with special reference to the celiomesenteric arterial trunk.

The course of celiac artery is described on the basis of studies on the carcases of 28 three-year old merino sheep of both sexes (7 males and 21 females). These investigations have shown that there are two main variants of the celiac artery. Of these, 60.7 percent of the sheep dissected exhibited the first, characterized by a separate issue of the celiac artery from the aorta. The second variant, characterized by the issue of the celiac artery from a celiomesenteric arterial trunk common to the celiac and superior mesenteric arteries, was found in 39.3 percent of the specimens. In the material studies, besides the variability in the course of the celiac artery, individual differences were found in the structure and topography of the neurovegetative vascular plexuses.

Hepatic arterial embolization in cases of extensive celiac arterial stenosis.

Transarterial hepatic embolization was attempted in 10 and succeeded in nine patients with hepatocellular carcinoma accompanied by extensive celiac arterial stenosis. All catheterization was done through the femoral artery. In six cases, the tip of the catheter (2.5-F ball-tip microcatheter in three cases, 4-F ball-tip supple catheter in three cases) was placed in the proper hepatic artery through the pancreaticoduodenal collaterals. In three cases, a ball-tip microcatheter was injected from the guiding catheter, which was placed in a pinhole of the celiac trunk. These techniques involving flow-guided ball-tip catheters are of great value for hepatic arterial catheterization in cases of extensive celiac arterial stenosis.
