Review
Vascular anatomical variations of the abdomen are very common. Awareness of these variations is of paramount importance in clinical practice mainly in achieving best results in minimal invasive or surgical vascular procedures. From surgical point of view, the preoperative knowledge of vascular anatomy and the relations to the surrounding structures and tissues aims to minimise inadvertent complications. Agenesis of the coeliac trunk is one of the rare anatomical variations of the abdominal aorta. Limited number of cases have been reported in the medical literature, most of which are based on angiographic and cadaveric studies of adult humans. In this paper, we report a case of absence of the coeliac trunk that has been detected as an incidental radiological finding in a female patient who was admitted with abdominal pain.

American Journal of Veterinary Research Mar 2009To evaluate short-term cardiovascular effects after IV administration of boluses of fentanyl in rabbits.
OBJECTIVE
To evaluate short-term cardiovascular effects after IV administration of boluses of fentanyl in rabbits.
ANIMALS
6 healthy New Zealand White rabbits.
PROCEDURES
Each rabbit was anesthetized with propofol (4.0 to 8.0 mg/kg, IV); anesthesia was maintained by administration of propofol (1.2 to 1.3 mg/kg/min, IV). Subsequently, 3 injections of fentanyl (0.0053 mg/kg) were administered. Before and for 10 minutes after injections, the following variables were measured: vessel diameter, peak systolic blood flow velocity, minimum diastolic blood flow velocity, end-diastolic blood flow velocity, time-average blood flow velocity, mean volumetric flow (VFmean), resistance index (RI), and pulsatility index for the left common carotid artery after the first injection and abdominal aorta after the third injection; mean arterial pressure (MAP); heart rate (HR); arterial oxygen saturation; end-tidal partial pressure of carbon dioxide; and body temperature. Echocardiography was performed after the second injection.
RESULTS
Fentanyl injections caused a transient and significant decrease in diameter and VFmean of the abdominal aorta and end-diastolic blood flow velocity of the left common carotid artery and an increase in peak systolic blood flow velocity and RI of the left common carotid artery. Also, MAP, HR, and body temperature decreased significantly after injections.
CONCLUSIONS AND CLINICAL RELEVANCE
Fentanyl injections induced a short-term decrease of vessel diameter in the abdominal aorta and increased resistance in the distal distribution area of the left common carotid artery. Results revealed decreases in MAP, HR, and body temperature, with an increasing effect after the third bolus injection, which indicated a cumulative drug effect.

We report on a unique clinically and surgically significant case of multiple abdominal aorta variations. Specifically, the left inferior phrenic, left gastric and splenic artery arose in common from the left aspect of the aorta constituting a common phrenogastrosplenic trunk, while the common hepatic artery originated separately from the midline of the anterior aspect of the aorta just inferiorly to the trunk. An accessory right hepatic artery arises from the right-anterior aspect of the abdominal aorta adjacent to superior mesenteric artery origin. On the left side, two renal arteries were observed. Moreover, the left gonadal artery exhibited a high origin, arising inferiorly to the upper left renal artery. We discuss about the embryological development of abdominal aorta arterial abnormalities and we attempt to sort the noticed variations according to existing classification in the literature. It is highlighted that the thorough knowledge of these arterial variations is important for the success of upper abdomen surgical operations such as liver and kidney transplantation, kidney preservation, abdominal aorta related vascular surgery, treatment of hepatocellular carcinoma by transcatheter arterial chemoembolizations as well as imaging interpretation of the region. Preoperative selective angiography or other abdominal aorta imaging studies are helpful for arterial variation demonstration and a precious tool for appropriate surgery planning.

The aim of the research was to examine the influence of orchidectomy on the elasticity and wall structure of the abdominal aorta in male rats and to check whether camelina oil treatment has an effect on aorta wall characteristics in orchidectomized rats. Forty 2-month-old male Wistar rats were used in the experiment: 10 animals underwent a sham testis repositioning operation (SHO) and 30 rats were orchidectomized (ORX). After the convalescence period, the SHO and ORX1 rats were given physiological saline intragastrically for 8 weeks; simultaneously, the other rats received camelina oil at the dose of 5 g/kg/b.w. (ORX2) or 9 g/kg/b.w. (ORX3) once a day. At the end of experiment, the animals were euthanized and fragments of the aorta were sampled for elasticity measurement and for histomorphometric and immunohistochemistry analysis. Orchidectomy caused a significant increase in the thickness of the total wall and its particular layers, mean intensity of elastin fluorescence in the tunica intima-media, and the volume of collagen I in tunica adventitia of the abdominal aorta in comparison to the other groups. The mean intensity of collagen I fluorescence in the tunica adventitia and tunica intima-media was significantly lower in the aorta of the orchidectomized rats. The values of the histomorphometric parameters of animals receiving camelina oil were lower than in the ORX1 group and higher than in the SHO rats. The values of the other parameters analyzed after the camelina oil treatment were similar to those in the SHO rats. In conclusion, our study showed that orchidectomy induced changes in the abdominal aorta wall characteristic for aging. Supplementation with camelina oil prevents negative consequences in the vessel wall structure in males with impaired endocrine function.

OBJECTIVE
Oxygen free radicals are important components involved in the histopathologic tissue alterations observed during abdominal aortic aneurysms (AAAs). This study examined whether melatonin has protective or therapeutic effects against AAAs.
METHODS
Sprague-Dawley rats were divided into four groups. A CaCl model was used to induce AAA. Starting on the operation day (Mel+AAA+Mel group) or 4 weeks after the operation (AAA+Mel group), the rats received intraperitoneal melatonin (10 mg/kg/day) for 6 and 2 weeks, respectively. The control and AAA groups received vehicle for 2 weeks after the sham operation and AAA induction, respectively. Angiographic measurements were recorded at the beginning, week 4, and week 6 of the study. After decapitation, aorta tissues were taken for the measurement of malondialdehyde, 8-hydroxy-2'-deoxyguanosine, glutathione levels, and myeloperoxidase and caspase-3 activity. Matrix metalloproteinase (MMP)-2, MMP-9, tumor necrosis factor-α, and inducible nitric oxide synthase protein expressions were analyzed by Western blot technique. Aortic tissues were also examined by light microscopy.
RESULTS
CaCl caused an inflammatory response and oxidative damage indicated by rises in malondialdehyde and 8-hydroxy-2'-deoxyguanosine levels. Myeloperoxidase and caspase-3 activities were increased, but glutathione levels were reduced. On the one hand, MMP-2, MMP-9, tumor necrosis factor-α, and inducible nitric oxide synthase protein expressions were increased in the vehicle-treated AAA group. On the other hand, melatonin treatment reversed all of these biochemical indices and histopathologic alterations.
CONCLUSIONS
According to the data, although melatonin tended to reverse the biochemical parameters given on week 4, the preventive effect is more pronounced when given concomitantly with AAA induction because values were closer to the control levels.
