Background: Injury to the celiac artery secondary to a blunt mechanism of trauma is an extremely rare injury that accounts for only 1%-2% of all visceral vascular lesions. Although rare, this injury is associated with significant mortality. Despite this high mortality, there are currently only a few published case series of blunt celiac artery injuries in the literature. This study sought to review all cases of blunt celiac artery injuries that presented to our Level I trauma center over a 5-year period., Methods: This was a retrospective chart review of all patients who presented with a traumatic blunt celiac artery injury between January 2012 and March 2017., Results: A total of 10 patients met the inclusion criteria for this study. The majority of patients were male (7/10, 70%), the average age was 38.3 ± 16.1 years, and overall mortality was 20% (2/10). On average, patients spent 10.2 ± 6.5 days in the hospital, 4.4 ± 4.5 days in the ICU, and 1.6 ± 2.0 days on the ventilator. The majority of patients presented with either an intimal dissection (3/10, 30%) or an intraluminal thrombus (3/10, 30%). Other injuries included pseudoaneurysms (2/10, 20%), complete avulsion (1/10, 10%), and an intimal dissection with thrombus (1/10, 10%). Of these injuries, 2 (20%) were noted to have retrograde flow on imaging studies including computed tomography angiography and a visceral angiogram. The majority of patients (8/10, 80%) were managed nonoperatively, and 5 (50%) patients were discharged home on aspirin. One patient who was initially managed nonoperatively required an unplanned return to the operating room for ischemic bowel, liver, and stomach. There were no other complications noted., Discussion: Traumatic blunt injury to the celiac artery is rare. Although there are multiple treatment options, there is currently no consensus in regard to management guidelines. In this case series, the majority of patients were successfully managed nonoperatively suggesting that a selective approach for intervention on patients with a blunt celiac artery injury should be considered.

Background: Isolated dissections of the celiac artery (CA) after blunt trauma are rarely described. This retrospective analysis and systematic review analyzes epidemiology, radiologic examinations, patterns of injuries, therapeutic measures, clinical courses, and outcomes., Methods: Retrospective analysis of polytraumatized patients admitted between 1997 and 2012 to a trauma center level I. Systematic literature search was carried out on pubmed.gov, eurorad.org, and google.com., Results: Isolated traumatic dissections of the CA had an incidence of 0.17% in a retrospective collective (n = 9). Mean age was 31.7 years in 6 male (66.7%) and 3 female (33.3%) patients. Systematic literature search identified 12 primary sources describing 13 males (100%) with a mean age of 41.3 years. Traffic accidents and falls were the most common causes of injury. An intimal flap (77.7%) and a thrombosed false lumen (59.1%) were the most common computed tomographic findings. Twenty-two patients were analyzed, and 16 patients were treated conservatively. The CA was bypassed in 2 symptomatic patients. One patient was treated with a stent. Two patients died because of massive bleeding, and 1 patient died because of liver failure. About 19 discharged patients were asymptomatic on follow-up. Long-term follow-up with magnetic resonance angiography showed stable dissections (n = 1), medium stenosis (n = 1), resolution of the dissection (n = 2), high-grade stenosis of the CA combined with a small pseudoaneurysm (n = 1), or occlusion of the CA with sufficient collateralization (n = 3). Pharmaceutical treatment was individualized with low-molecular-weight heparin, heparin, or warfarin, and acetylicsalicylic acid., Conclusions: Traumatic CA dissections are mostly caused by traffic accidents and falls. Visceral perfusion should be monitored clinically and radiologically. Beginning visceral ischemia requires early invasive treatment. Endovascular and open surgery are possible options. Benefits of specific pharmaceuticals are still up for debate. Follow-up via magnetic resonance imaging or computed tomography angiography is essential to rule out vascular complications., Level of Evidence: III (Retrospective therapeutic study and systematic literature review)., (Copyright © 2020 Elsevier Inc.

Purpose: To identify the incidence and outcomes of iatrogenic celiac and hepatic artery dissections during transarterial therapies, including bland embolization, chemoembolization, radioembolization (TARE), and pre-TARE scintigraphic mapping., Methods: The institution's quality assessment database, electronic medical record, and picture archiving and communication system were reviewed to identify all patients who underwent transarterial locoregional therapy from 1/2001 to 7/2017 and to determine the incidence of iatrogenic dissection, to assess patency of the arteries after dissection, and to assess the ability to complete therapy., Results: 2253 patients underwent 3776 transarterial hepatic oncology procedures. Among 3776 procedures, 40 (1.1%) were associated with dissection of the visceral vasculature, affecting 39 patients (1.7%). The incidence of flow-limiting dissections was 0.3% (13/3776) and non-flow-limiting dissections was 0.7% (27/3776). After dissection, 68% (27/40) of treatments were completed the same day. Among the 13 aborted treatments, 8 (62%) were completed on a subsequent encounter. Follow-up imaging was obtained in 26 of 40 cases at median time of 63 days. Complete resolution of the dissection was seen in 15/26 cases (58%), near complete resolution (< 30% luminal narrowing) in 3/26 (12%), unchanged appearance of a non-flow-limiting dissection in 4/26 (15%), progressive luminal narrowing in 3/26 (12%), and complete occlusion in 1/26 (4%)., Conclusion: Iatrogenic dissections of visceral arteries rarely occur during tumor embolization procedures. 35/39 (90%) of patients underwent successful treatment despite the dissection.

An 18-year-old male patient presented to our regional referral hospital postcollapse at home. This was about 48 hours following a 2 m fall from a mountain bike. CT scan at presentation showed a grade 3/4 laceration at the splenic lower pole with some haemoperitoneum. He was managed conservatively. However, on day 4 he developed increasing abdominal pain which prompted repeat CT abdominal angiography. This scan did not show any further active bleeding from the spleen, however, a coeliac artery dissection was discovered, which was not evident on the first scan. After liaison with the vascular surgery team at a tertiary hospital, this was treated conservatively. Coeliac artery dissection following blunt trauma is an extremely rare occurrence, with fewer than 10 cases described in the literature. To our knowledge, this is the first case of concurrent splenic injury and coeliac artery dissection following blunt trauma to be reported., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019.

Rationale: Blunt injury of major visceral arteries such as celiac artery (CA) and superior mesenteric artery (SMA) are very rare but fatal, therefore, these injuries are challenging to trauma surgeons. The patient with occlusion of CA or SMA is theoretically viable by visceral collateral circulation. However, there are very rare cases in clinics. To date, there have been few reports of both CA and SMA occlusions after blunt trauma. Herein we describe our successful conservative treatment of patients with both CA and SMA occlusions., Patient Concerns: Fifteen-year-old girl suffering from schizophrenia was transferred to our hospital after a fall from 3-floor-height with a purpose of suicide., Diagnoses: An abdominal computed tomography (CT) scan with contrast enhancement showed proximal CA and proximal SMA occlusions with surrounding retroperitoneal hematoma, however, distal parts of occlusion were supplied by the collateral vessels (enlarged marginal artery of left colon from inferior mesenteric artery and pancreaticoduodenal arcade)., Interventions: She was treated by only supportive care without anticoagulant due to retroperitoneal hematoma., Outcomes: The patient was discharged 25 days after admission without complications., Lessons: We think that our patient could survive because her vascular status was healthy and collateral circulations were plenty according to the young age. We believe that this case can provide a basis for ligation in these forbidding and handless major visceral arterial injuries such as CA or SMA.

Purpose: The incidence of intraoperative arterial injury during pancreatectomy is not well described. This study aims to evaluate the incidence, management, and outcome of arterial injuries during pancreatectomy., Methods: This is a retrospective study of 1535 consecutive patients undergoing pancreatectomy between 2006 and 2016 at Oslo University Hospital. The type of arterial injury and potential contributing factors were analyzed. Short-term outcomes were compared between patients with arterial injury and patients undergoing a planned arterial resection due to tumor involvement., Results: Arterial injury was diagnosed in 14 patients (incidence 0.91%), while planned arterial resection was performed in 22 patients. The injuries were located in the superior mesenteric artery (n = 5), right hepatic artery (n = 5), common hepatic artery (n = 2), left hepatic artery (n = 1), and celiac trunk (n = 2). The artery was reconstructed in all except one patient. In 11 patients with injury, peripancreatic inflammation, aberrant arterial anatomy, close relationship between tumor and injured artery, or a combination of the three were found. Median estimated blood loss was 1100 ml in both groups. Rate of severe complications (≥ Clavien grade IIIa), comprehensive complication index, and 90-day mortality for patients with intraoperative arterial injury vs planned arterial resection were 43 vs 45% (p = 0.879), median 35.9 vs 21.8 (p = 0.287), and 14.3 vs 4.5% (p = 0.551), respectively., Conclusion: Arterial injury during pancreatectomy is an infrequent and manageable complication. Early recognition and primary repair in order to restore arterial liver perfusion may improve outcome. However, the morbidity is high and comparable to patients undergoing a planned arterial resection.

Celiac artery (CA) injuries are very rare and are often associated with high mortality. These injuries are associated more often with penetrating trauma rather than blunt trauma injury. Our case highlights a blunt trauma injury of CA in a hemodynamically stable patient without any symptoms that was treated conservatively., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Celiac trunk injures are rare events, with high mortality rates and difficult management. Endovascular treatment may be considered to avoid bleeding. We report a case of severe bleeding in a 37-year-old man resulting from celiac trunk stretching after a motorcycle crash. Because direct celiac trunk catheterization was not possible, a retrograde catheterization of the common hepatic artery was performed via the superior mesenteric artery. Two vascular plugs (type IV) were released, and the exclusion of the celiac trunk origin was completed with the deployment of an aortic cuff. The patient's clinical condition immediately improved, and after 6 months' follow-up, imaging confirmed the complete exclusion of the celiac trunk.

We report 2 cases of complicated spontaneous dissection of the celiac artery, which were successfully treated by a stent graft. The first patient was a 47-year-old man who presented with acute abdominal pain. CT scan showed ruptured saccular aneurysm with surrounding retroperitoneal hematoma. The second patient was a 57-year-old man with progressive dissecting aneurysm. Endovascular stent graft was placed in the celiac trunk to control bleeding, and to prevent rupture in each patient. Follow-up CT scans showed complete obliteration of a dissecting aneurysm.

Traumatic detachment of the celiac trunk from the abdominal aorta is a rare clinical situation, and proper treatment options have not been established. We report a patient with traumatic separation of the celiac trunk treated by bridging with a covered stent between the celiac trunk and abdominal aorta.

We report a case of iatrogenic resection of both the superior mesenteric artery (SMA) and celiac artery during left nephrectomy and adrenalectomy. A 47-year-old woman was diagnosed with a large adrenal tumor and underwent a laparoscopic left adrenalectomy that was converted to open adrenalectomy and nephrectomy as a result of a bulky tumor. Both the SMA and celiac artery were inadvertently cut at their origin because of adherence of the tumor to the aorta. Both arteries were revascularized by anastomosing the distal splenic artery to the aorta after performing splenectomy to revascularize the celiac circulation and using an autologous saphenous vein graft to revascularize the SMA. The patient had no postoperative complications. To our knowledge, this is the first description of use of the splenic artery for celiac revascularization., (Copyright (c) 2010 Annals of Vascular Surgery Inc. Published by Elsevier Inc.

We provide the description of a 77 year old patient, admitted into the IC unit, with whom the surgical intervention was required by the presence of a massive pneumoperitoneum observed during abdominal CT. Anamnestic and clinical information was scarce; the patient had been admitted into the gastroenterology unit with the following diagnosis: acute pancreatitis, renal failure, atrioventricular block, while the hemodynamic instability made hospitalisation into the IC unit mandatory. Anatomopathological lesions secondary to a major vascular damage at the level of the celiac trunk and at the superior mesenteric level were noticed intraoperatively: total gastric necrosis with perforation, splenic infarction, entero-mesenteric infarction, abdominal wall necrosis. The patient did not allow for a surgical solution. The anatomopathological examination of the gastric tissue fragment enabled the diagnosis of extensive gangrene of the gastric wall. The relevance of the case consists in the presence of an abdominal vascular damage detected in full development, where the pneumoperitoneum required surgical exploration. The intricacy of the anatomopathological lesions accounts for the acute painful abdominal onset, accompanied by quick hemodynamic, clinical, and biochemical deterioration. Thus, gastric perforation through rupture secondary to total gastric gangrene of vascular origin joins the many causes of pneumoperitoneum.

Injuries of the abdominal visceral vessels are uncommon but devastating entities resulting in extremely high rates of mortality. The most common cause of abdominal vascular injuries is penetrating trauma, accounting for 90% to 95% of these injuries. In contrast, blunt trauma accounts for 5% to 10% of all abdominal vascular lesions. Although traumatic injury to the celiac artery is among the rarest of all vascular injuries, mortality can be as high as 75%. We report a 66-year-old patient who sustained multiple injuries in a motor vehicle crash. The initial whole-body computed tomography (CT) scan revealed a combination of severe brain injury and bilateral thoracic lesions. On day 6 after the accident, the patient's clinical situation deteriorated rapidly. At this time, the abdominal arterial CT scan showed a dissection of the celiac artery. Therapeutic anticoagulation was not feasible because of the intracranial hemorrhage. Also the patient's clinical situation worsened so rapidly that interventional therapy, including surgical and endovascular treatment, could not be performed. Finally, the patient died of fulminant hepatic failure, therefore not surviving a potentially treatable injury. The diagnosis of celiac artery dissection in this patient was significantly delayed because the initial trauma CT protocol did not include an arterial phase of the abdominal vessels.

Objectives: Celiac axis injuries are rare. The purposes of this study were to (1) review institutional experience, (2) determine additive effect on death of associated vessel injuries, and (3) correlate mortality rates with the American Association for the Surgery of Trauma-Organ Injury Scale (AAST-OIS) for abdominal vascular injury., Methods: This was a retrospective, 132-month study (January 1992 to December 2002) of patients with celiac axis injuries., Results: Thirteen patients were included in the study. Mean revised trauma score was 5.35+/-2.63; mean injury severity score was 25+/-12. The mechanism was penetrating in 12 (92%) and blunt in 1 (8%); 3 of 13 had Emergency Department thoracotomy (100% mortality rate). Treatment included ligation in 11 and primary repair in 1; 1 exsanguinated. Overall survival was 5 of 13 (38%). Adjusted survival excluding patients who had Emergency Department thoracotomy was 5 of 10 patients (50%). Those surviving with isolated injuries included 57% of patients. Mortality rate versus AAST-OIS was grade III, 43% (3 of 7 patients); grade IV, 50% (1 of 2 patients); and grade V, 100% (4 of 4 patients)., Conclusions: Celiac axis injuries are rare. Patients with isolated injuries have better survival rates. Mortality rate correlates well with AAST-OIS for abdominal vascular injury.

We present our experience in the nonoperative management of iatrogenic lesions of celiac branches by using transcatheter arterial embolization. We treated 6 pseudoaneurysms (5 intrahepatic and 1 of the gastroduodenal artery), 6 vessel lacerations (1 common hepatic artery, 1 right hepatic artery, 1 gastroduodenal artery, 2 pancreatoduodenal, 1 polar intrasplenic artery), 1 arterioportal fistula, and 1 arteriobiliary fistula; all the bleeding lesions were secondary to surgical, endoscopic, or interventional radiologic procedures.

Limitation of the damage to the organs such as heart, liver, intestine, stomach and brain by an earlier brief complete occlusion of their arteries is defined as ischemic preconditioning (IP). No study so for has been undertaken to check whether brain-gut axis is involved in the gastroprotection exhibited by gastric IP or in that induced by repeated brief episodes of ischemia of remote organs such as heart and liver. This study was designed to determine the possible involvement of vagal and sensory afferent nerves, in the mechanism of gastric and remote organ IP on the gastric mucosa in rats exposed to prolonged ischemia-reperfusion with or without functional ablation of sensory nerves by capsaicin or in those with removed vagal innervation by vagotomy. This gastric IP was induced by short ischemia episodes (occlusion of celiac artery 1-5 times for 5 min) applied 30 min before subsequent ischemia followed by 3 h of reperfusion (I/R) and compared with remote IP induced by occlusion of left descending coronary artery or hepatic artery plus portal vein. The area of gastric lesions was determined by planimetry, gastric blood flow (GBF) was measured by H(2)-gas clearance method and mucosal biopsy samples were taken for the assessment of calcitonin gene-related peptide (CGRP) by RIA. Exposure of gastric mucosa to standard 3 h of I/R produced numerous gastric lesions and significant fall in the GBF and mucosal CGRP content. Two 5 min short ischemic episodes by occlusion of coronary or hepatic arteries, significantly reduced gastric damage induced by I/R with the extent similar to that exhibited by two short (5 min) episodes of gastric ischemia. These protective effects of gastric and remote IPs were accompanied by a restoration of the fall in the CGRP content caused by I/R alone. Protection and hyperemia induced by gastric IP were significantly attenuated in capsaicin-denervated or vagotomized animals and completely removed in those exposed to the combination of vagotomy and capsaicin-denervation. The IP-induced protection and hyperemia were restored by the administration of exogenous CGRP to gastric IP in capsaicin-treated animals. Gastroprotective and hyperemic actions of remote IP were markedly diminished in capsaicin-denervated rats and in those subjected to vagotomy. We conclude that brief ischemia in remote organs such as heart and liver protects gastric mucosa against gastric injury induced by I/R as effectively as gastric IP via mechanism involving both vagal and sensory nerves releasing vasodilatatory mediators such as CGRP.

The report describes a previously healthy 24-year-old women presenting with acute abdominal pain following a hyperextension manoeuvre. The key finding of a continuous bruit with systolic and diastolic components in the epigastric region subsequently led to the diagnosis of an intramural haematoma of the coeliac artery, that caused a subtotal occlusion of the artery. The diagnosis was achieved by both colour-coded duplex sonography and magnetic resonance angiography. The case shows that a conservative management rather than operative reconstruction is justified in an oligo-symptomatic situation with no signs of end-organ damage as in this patient.

This article deals with injuries to the celiac trunk, superior and inferior mesenteric arterial injuires. Surgical approaches and physiological implications of interruption of the mesenteric arterial circulation are addressed in detail. Surgical techniques for the management of these injuries and the need for second look operations are also examined.

Spontaneous dissection of the celiac artery (CA) is uncommon, considering the number of isolated lesions without associated aortic dissection and exclusive of abdominal trauma. We have treated five cases of isolated spontaneous dissection of the CA or its branches. There were three men and two women with a mean age of 54 years. The presenting manifestation was acute epigastralgia in three cases and chronic abdominal pain in one. In the remaining case, dissecting CA was a coincidental finding. All patients underwent abdominal Doppler ultrasound and CT scan imaging, which demonstrated aneurysm in three cases and dissection in two. Work-up also included arteriography in three cases and magnetic resonance (MR) angiography in one. Management consisted of emergency surgical repair in three cases and close surveillance in two. The repair procedure was resection-anastomosis in one case and prosthetic bypass to the hepatic artery in two cases. Postoperative recovery was uneventful in all three cases and patients were symptom-free at 6, 8, and 18 months. Both patients under surveillance were symptom-free at 1 and 2 years. Because of the risk of ischemic and hemorrhagic complications, surgery should be considered for any patient with CA dissection. However, some patients with uncomplicated asymptomatic lesions may be eligible for medical treatment with regular surveillance.

Purpose: To study the sequelae of iatrogenic dissection of the celiac axis and its branches in a large patient population., Methods: We analyzed 40 patients with hepatocellular carcinoma (HCC) whose celiac artery or its branches were dissected during transcatheter arterial embolization (TAE) and underwent follow-up angiography within 2 months., Results: The two most common sites of dissection were the celiac artery in 13 patients (32.5%) and the proper hepatic artery in 11 patients (27.5%). Follow-up angiography revealed complete recanalization in 32.5% (13/40), irregularity and narrowing of the lumen in 40% (16/40), and complete obstruction in 27.5% (11/40). Therefore, 72.5% (29/40) of the dissected arteries recanalized. Pseudoaneurysm formation of the dissected artery was observed in 32.5% (13/40). Subsequent TAE was possible via the dissected arteries in 79% (27/34) of patients in this series., Conclusion: Iatrogenic dissection of the celiac and proximal hepatic arteries heals spontaneously in the majority of patients, and in most instances allows subsequent TAE.

The superior mesenteric artery and celiac axis were inadvertently ligated during left radical nephrectomy for a large upper pole renal carcinoma with massive perihilar and periaortic adenopathy. Computer-generated 3-dimensional illustrations created from the computerized tomography scan demonstrated the close proximity between these visceral branches and the adenopathy mass complex, and showed how this bulky disease may interfere with surgical anatomy. When left radical nephrectomy is performed for locally advanced and/or bulky node-positive renal neoplasms, surgeons must be cognizant of the location of the major visceral arterial branches and possible anatomical distortions.

We report a case of traumatic rupture of the thoracoabdominal aorta that was successfully repaired 3 days following the accident. Associated lesions included rupture of the left renal and celiac arteries. This rare lesion should be suspected in the victims of violent hyperextension of the body with or without a fracture of the dorsolumbar spine. Aortography is diagnostic. Whenever possible preoperative angiographic visualisation of the spinal cord arterial supply should be performed.

Celiac artery aneurysms were encountered in nine patients, ranging in age from 39 to 76 years, at the University of Michigan Medical Center between 1961 and 1983. Developmental defects and atherosclerosis were etiologic factors in six cases. Four patients were without symptoms, whereas five experienced abdominal pain, including one with a ruptured aneurysm. Eight patients were subjected to surgical treatment; no deaths occurred and symptoms were resolved in all patients. A literature review of 108 celiac artery aneurysms revealed two distinct subgroups. Among 60 celiac artery aneurysms encountered before 1950, representing the historic era, 40% were infectious (usually luetic), 7% were traumatic, and 52% were of undetermined cause. Most were symptomatic, 87% ruptured, and 95% were diagnosed at postmortem examination. The contemporary era since 1950 consisted of 48 cases, including nine in the Michigan experience. Congenital or developmental medial defects of the arterial wall and atherosclerosis were the most common causes of aneurysms. Most aneurysms in the contemporary period were either asymptomatic or accompanied by vague abdominal discomfort. Rupture affected 13% of those aneurysms. Operative therapy was successfully undertaken in 91% of 43 patients during the contemporary era, including eight in the present series.

Injuries of the major visceral arteries are among the more difficult to manage and rarely occur without serious associated injuries. Sixty-six patients are presented with injuries to the celiac, superior, and inferior mesenteric arteries. Fifty-three injuries resulted from gunshot wounds, nine from stab wounds, and four from blunt trauma. Operative management included vessel ligation in 11 patients, arteriorrhaphy in 43, resection and end-to-end anastomosis in six, Dacron graft interposition in four, and aortic reimplantation in two. Twenty-three patients died, 16 from failure to control hemorrhage. In two patients failure to restore adequate visceral circulation resulted in bowel ischemia and infarction. The successful management of patients with visceral arterial injuries is dependent upon rapid and adequate exposure followed by primary repair or revascularization utilizing available surgical techniques.

A review of our experience with urban children who sustained blunt abdominal trauma revealed that liver trauma occurred in one-third of all children. The cause of trauma, predominantly blunt in nature, led to a multitude of associated injuries which not only caused visceral and skeletal injury endangering the patient, but, more apparent even though less significant injuries delayed diagnosis and therapy of the underlying sever liver injury. Awareness of the possibility of liver injury in children with blunt abdominal trauma, prompt operative intervention wil injuries should significantly increase the salvage of these pediatric trauma victims.

The authors report a rare case of iatrogenous arteriovenous fistula between left gastric artery and vein, arising after gastric resection. The observation caused a reviewing of the literature (19 cases published, of which only one between left gastric artery and vein) and some remarks about the physiopathology, pathological anatomy, clinics and treatment of such rare diseases. The authors, in their conclusions, emphasize that such arteriovenous fistulas can remain asymptomatic for a long time; they, moreover, with evident effects on the liver physiology, can progressively cause a serious state of portal hypertension, in the genesis of which the time-factor plays a primary role.
