Celiac Artery

The celiac artery is a major blood vessel that supplies oxygenated blood to the upper abdomen, including the stomach, liver, spleen, and portions of the pancreas and small intestine.
It branches off from the abdominal aorta and divides into several smaller arteries that nourish these vital organs.
Understanding the anatomy and physiology of the celiac artery is crucial for medical professionals when diagnosing and treating conditions affecting the upper gastrointestinal tract, such as celiac disease, pancreatitis, and liver disorders.
PubCompare.ai's innovative AI-driven platform can help researchers explore the celiac artery in depth, optimiize research protocols, and enhance the reproducibility of their studies through data-driven insights and comparisons.

Donor livers were obtained from the New England Organ Bank (NEOB) with consent for research from the family after being turned down for clinical transplantation. Extubation of donors after circulatory death was performed by the primary service, which was also responsible for declaration of death 5 minutes after circulatory cessation. The procurement procedure did not begin until after declaration of death. Standard procurement technique includes an in situ flush with University of Wisconsin (UW) solution, intra-abdominal cooling with ice, and an additional back table UW flush. The gallbladder was incised, aspirated of bile, and irrigated with saline. The common bile duct was flushed with UW solution. The relative warm ischemic time for DCD livers is defined as the time between extubation and in situ cold flushing, whereas absolute warm ischemic time begins after circulatory cessation and ends at in situ cold flushing. Donor livers were transported in sterile bags cooled on ice. On arrival at our center and during the priming of the machine perfusion system the donor liver was prepared for connection to the system. The portal vein and hepatic branches of the celiac trunk and/or superior mesenteric artery were dissected free. The portal vein was cannulated distally with a section of tubing (Masterflex 24 L/S, Cole Palmer, Vernon Hills, IL). The aortic segment was opened and the celiac trunk was cannulated at the origin with a vessel cannula (Medtronic, Minneapolis, MN). Other branches of the celiac trunk were tied using 0 silk sutures. The cystic duct was ligated and the gallbladder flushed of residual bile. The common bile duct was cannulated with a vessel cannula, which was then connected to a section of tubing to allow bile collection. All cannulae were secured using 0 silk sutures.
Approval was obtained from the NEOB for the perfusion of discarded human donor livers and this study was declared exempt by the Massachusetts General Hospital (MGH) institutional review board (IRB # 2011P001496).

Maps of aortic hemodynamics were derived based on home-built analysis tools (MatLab; MathWorks, Natick, MA) similar to a recently reported workflow.25 (link) The 4D flow velocity data were regridded to isotropic 1 mm3 voxels using spline interpolation. A 3D aortic centerline was calculated and orthogonal planes were automatically placed every millimeter.26 Each voxel was matched to the nearest plane (ie, having center point at shortest 3D distance) to determine directional flow along the centerline, ie, forward (AAo to DAo) and reverse (ie, DAo to AAo); see Fig. 1f,g. For each voxel inside the TL and FL (DAD patients) or entire aorta (controls), net forward flow (FF) and reverse flow (RF) were calculated as the sum over the cardiac cycle.
The velocity magnitude was determined for each voxel at each cardiac time-frame, ie, v(t). Voxelwise flow stasis was calculated as the percentage of cardiac timeframes with v(t) < 0.10 m/s. In addition, voxelwise kinetic energy (KE) was determined by:
KE=12ρdVv(t)2
with ρ the blood density assumed as 1060 kg/m3 and dV the unit voxel volume (ie, 1 mm3)27 ,28 (link) and summed over the cardiac cycle.
To correct for errors in plane orientation at the beginning and end of the centerline, the first and last four orthogonal planes along the centerline were not included in the directional flow quantifications. To reduce noise, a 3D median 3-by-3-by-3 filter was applied to all voxelwise parameters.
To provide an intuitive visualization of the spatial distribution of hemodynamic parameters across the TL and FL (patients) or entire aorta (controls), anatomic maps for FF, RF, stasis, and KE were calculated. The 3D voxelwise data for each parameter was collapsed into an average intensity projection, ie, average of all voxels in the segmented TL or FL (patients) or aorta (controls) along the projection direction. For quantitative regional analysis, the aorta was separated into five regions of interest (ROIs): 1) AAo (aortic root to brachiocephalic artery); 2) aortic arch (brachiocephalic artery to left subclavian artery); 3) proximal-DAo (left subclavian artery to vertical DAo); 4) mid-DAo (vertical DAo to half the distance to the celiac trunk); and 5) distal-DAo (distal edge of ROI 4 to the celiac trunk) (Fig. 1h). For each ROI, the mean FF, RF, KE, and flow stasis were quantified. For quantification in the FL, only ROIs containing at least 4000 voxels (=4 mL) were included to ensure a sizeable flow region for quantification.

Patients were treated with TACE following standard local protocol. Each indication of TACE was validated during multidisciplinary tumor board including a hepatologist, an interventional radiologist, and a liver surgeon. Procedures were realized in an interventional radiology suite (Allura Integris, Philips Medical Systems, Eindhoven, Netherlands). The contrast media used was Xenetix 350 (Xenetix®, Guerbet, Roissy, France). First, diagnostic arteriography was performed under local anesthesia, through the right femoral artery, using a 4-French introducer sheath. Portal vein patency and arterial vascular anatomy were appreciated due to the catheterization of the superior mesenteric artery and the coeliac trunk (Figure 1). Chemoembolization was as selective as possible according to tumor localization and number. The use of a microcatheter was left to the radiologist’s discretion. cTACE or DEB-TACE could be performed. During cTACE, 50 mg of injectable lyophilized doxorubicin (Adriblastina®, Pfizer Pharma, United States) or 10 mg of injectable lyophilized idarubicin (Zavedos®, Pfizer Pharma, United States) were manually emulsified with 5-10 mL of iodized oil (Lipiodol® Ultra Fluide, Guerbet, France) before infusion. Drug-eluting beads (100 µm; Embozene Tandem® microspheres, Celonova Biosciences, Germany) were used for DEB-TACE procedures. Lipiodol emulsion or DEB were injected until saturation of tumor feeding arteries. In the case of cTACE, drug administration was immediately followed by embolization using absorbable gelatine sponge (Curaspon®; Curamedical, Netherlands) to obtain an arterial flow stop during 10 min. As recommended by European guidelines and as routinely done in our department, TACE could be repeated 2 mo after the first treatment in case of partial response (PR) on postoperative scan[12 (link)].

Automated segmentation of the stomach, liver, GB, pancreas, spleen, rib, skin, and abdominal wall was performed on the portal phase CT image using a deep learning algorithm based on fine-tuned 3D U-Net. 3D U-Net is a specialized deep learning algorithm for biomedical image segmentation, and this algorithm used its own fine-tuned model with learning from radiologists-annotated clinical data. On the early arterial and the portal phase CT images, biomedical engineers used semi-automatic segmentation software (AVIEW, Coreline Soft, Seoul, Korea) and segmented upper abdominal vessels which were essentially needed for making a surgery-oriented 3-D model as follows: aorta, celiac artery, left and right gastric arteries, splenic artery, common hepatic artery, proper hepatic artery, left hepatic artery, right hepatic artery, aberrant hepatic artery if present, gastroduodenal artery, left and right gastroepiploic arteries, inferior vena cava, portal vein, splenic vein, left gastric vein, and left and right gastroepiploic veins. For 3-D reconstruction, 3-D masks of organs and vessels were obtained from this segmentation process and inspected by one radiologist with 19 years of experience in abdominal imaging.

TACE was performed by experienced interventional radiologists with over 10-year experience (K.J. and C.Y.). The modified Seldinger method was adopted to puncture the femoral artery and insert a 5 F catheter sheath in patients under local anesthesia. The 4 F RH catheter was used for selective catheterization into the celiac trunk artery and superior mesenteric artery for angiography to verify the anatomical structure of the variant hepatic artery. Computed tomography during hepatic angiography and arterial portography was performed to evaluate the locations, sizes, numbers and patency of tumors supplying arteries and portal veins. Then, the microcatheter was superselective intubated into the third or fourth hepatic artery branch supplying blood to the target tumor. The infusion of iodized oil (2–20 ml) and adriamycin (10–60 mg) was injected, followed by embolization with gel foam particles (150–350 μm or 350–560 μm). The endpoint of embolization was that the tumor intravascular blood flow was significantly reduced compared with the initial blood flow, and the contrast medium was not emptied in 3–5 cardiac cycles. The doses of the chemotherapeutic drugs and embolization materials were decided according to the tumor burden, tumor characteristics and hepatic functional reserve [20 (link)]. None of the patients in this study underwent drug-eluting beads-TACE (DEB-TACE).
Adverse events (AEs) were evaluated in accordance with the National Cancer Institute Common termination criteria for adverse events version 5.0, and the AEs were divided into five levels according to the severity. Grade 1: asymptomatic or mild, only clinical or diagnostic findings, without treatment; Grade 2: requires minor, local or noninvasive treatment; Grade 3: serious or medically significant but not immediately life-threatening, resulting in hospitalization or prolonged hospitalization; Grade 4: life-threatening; emergency treatment is required; Grade 5: AE related death.
CT or MRI examination was performed at 6–8 weeks after TACE. For patients with residual activity of tumor or new lesions, ‘on-demand’ TACE was performed according to the tumor response and hepatic functional reserve. The modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria [21 ] were used to evaluate the tumor response. CR and partial response (PR) were considered as the presence of radiological responses, whereas stable disease (SD) and progressive disease (PD) were considered as the absence of radiological response. The time of all-cause death or last follow-up of the patients was recorded by reviewing the medical records or telephone follow-up. The date of last follow-up in this study was 30 November 2020.

LPD was performed on the patient lying on his back, with his legs separated and in a slight anti-Trendelenburg position. A holder of the mirror stood between the legs, with an operator and an assistant on either side of the patient. A total of 5 trocars were placed. Three trocars with a diameter of 12 mm were located about 5 cm below the umbilicus and on the left and right sides of the umbilicus, respectively. Two 5 mm trocars were placed in the left and right epigastrium. Except 2 cases with Olympus 3D laparoscopy, the rest were performed with 30° 2D laparoscopy.
All cases underwent partial distal gastrectomy without preserving pylorus. Patients with malignant tumors underwent lymph node dissection, including duodenal ligament, common perihepatic artery, peripancreatic head, celiac trunk, and left superior mesenteric artery lymph nodes. Concomitant portal vein and/or superior mesenteric vein (PV/SMV) resection is performed on patients with possible or definite tumor invasion. The reconstruction process was carried out by a “CHILD” method. The upper intestinal segment was lifted to the subhepatic portion through the mesenteric root. First, pancreaticoenterostomy was performed at about 5 cm away from the ruptured end of the jejunum. Second, choledochojejunostomy was performed at about 5-15 m away from the position of pancreaticoenterostomy. When the diameter of bile duct was ≥1.0 cm, 4-0 V-Loc was used for end-to-end anastomosis of bile duct and jejunum; when the diameter of the bile duct was less than 1.0 cm, 4-0 Monocryl suture was used for intermittent suture and placed internal stents. Finally, the gastrojejunal side-to-side anastomosis was performed before the colon. A drainage tube was placed in front of and behind the pancreaticoenterostomy site.

An abdominal CT scan with contrast and/or a CT angiography (CTA) scan was then obtained. If signs of active bleeding (contrast pooling and/or extravasation) or pseudoaneurysm were observed on the CT scan, angiography was suggested. If there was no active bleeding sign but clinical suspicion remained high, with or without unstable vital signs, angiography was also indicated. The right or left common femoral artery was accessed using a puncture needle, which was then exchanged for a size 5 French sheath via the Seldinger technique. An angiogram of the celiac trunk, the superior mesenteric artery, and/or the common hepatic artery was obtained with an angiographic catheter for evaluation of the bleeding site. Positive angiography findings were defined as contrast extravasation/pooling or pseudoaneurysm. After evaluation of the GDA stump, with or without pseudoaneurysm, conservative treatment or TAE was performed. The patients were retrospectively split into three groups, according to their treatment: conservative treatment without embolization (group A), hepatic artery sacrifice/embolization (group B), and GDA stump embolization (group C).
In group A, conservative treatment without TAE was performed under close observation in the intensive care units. This group was divided into two subgroups: subgroup A1, for those who had negative angiography findings, and subgroup A2, for those who had hemodynamically stable vital signs, with positive contrast extravasation and/or pseudoaneurysm.
Two embolization techniques were performed: hepatic artery sacrifice/embolization (group B) and GDA stump embolization (group C). In group B, a microcatheter was advanced through the hepatic artery, distal to the GDA stump. Then, micro-coils were deployed to achieve the embolization of the proper/common hepatic artery, proximal to the GDA stump. After embolization, a complete celiac angiogram was performed to confirm the effects of TAE, such as sacrifice/complete (subgroup B1) or incomplete (subgroup B2) occlusion/embolization of the hepatic artery. The sacrifice of the hepatic artery involves embolism opacification in the hepatic artery, without patent blood flow; incomplete embolization involves embolism opacification in the hepatic artery, with residual partial hepatic artery flow. In group C, selective embolization of the GDA stump and/or pseudoaneurysm was carried out to preserve the hepatic arterial flow. Micro-coils were deployed to achieve the complete occlusion of the GDA stump.

Two abdominal radiologists with 24 and 12 years of experience independently evaluated the DCE-MRI image quality. They reviewed the images using cine mode, with all images from the same section being presented sequentially. Five items (pancreas edge sharpness, motion artifact, streak artifact, noise, and overall image quality) were evaluated with a five-point scale. A score of 1 indicated the most severe image degradation or the worst image quality, and a score of 5 indicated the fewest artifacts/least noise or the best image quality. Pancreas edge sharpness was evaluated on the section that covered the largest area of the pancreas. For the determination of the motion artifact, the presence of multiple lines parallel to the abdominal wall that caused the blurring of the abdominal wall was evaluated. Streak artifact usually appeared as multiple radial lines around the very bright structures or structures outside the field of view. Two radiologists reviewed all of the available images in consensus to determine whether a focal lesion was in the pancreas and made a diagnosis for the focal lesion.
Image processing and analysis for the DCE-MRI was performed using an application for evaluating DCE-MRI (MR Tissue4D) based on commercial software (Syngo.via VB30A, Siemens Healthineers). The perfusion maps were generated using a population-based arterial input function within a sphere-shaped volume of interest containing the entire pancreas and adjacent vessels. Although the software application provided parametric maps based on the Tofts model, we only used measurements from the time–intensity curve. One abdominal radiologist with 12 years of experience in pancreatic MRI performed the image analysis and measured the pancreatic duct diameter in the head, body, and tail of the pancreas. The radiologist also drew six regions of interest (ROIs) in three areas of the vessels (the descending aorta at the left crus level, celiac axis, and superior mesenteric artery (SMA)) and three areas of the pancreas (head, body, and tail). The demarcation of the head, body, and tail of the pancreas was based on the 8th edition of the American Joint Committee on Cancer (AJCC) system [16 ], as follows: the head is to the right of the superior mesenteric–portal vein confluence, the body is between the left border of the superior mesenteric vein and the left border of the aorta, and the tail is between the left border of the aorta and the hilum of the spleen. ROIs in the vessels were free-hand drawn as large as possible while avoiding the vessel wall, and those in the pancreas had sizes larger than 50 mm2. From each ROI, we measured the peak-enhancement time, which is the time between the start of image acquisition and the highest signal intensity. The delay time was based on the time elapsed between the peak-enhancement time in the aorta and the pancreas. The peak concentration in the ROI was recorded from the time–intensity curve. Figure 1 depicts the concepts of the investigated parameters (Figure 1).
