A Study of the Right Colonic Vascular Anatomy: Correlations between Veins and Arteries

The purpose of our research consists of studying a new dye which, besides allowing the macroscopic study of small vessels <FONT FACE=Symbol>¾</FONT> following the pioneer research of Salmon(3) <FONT FACE=Symbol>¾</FONT>, permits the radiographic study due to its radiopacity. To do so, ten rats were utilized and their abdominal aorta was catheterized for the injection of the dye towards the periphery, being the flow of the dye observed along the left femoral artery (the right one was cauterized for occlusion). The results of this injection revealed that the dye penetrates well in extremely small vessels and allows dissection without extravasations. Thus, we believe that this dye has the necessary requirements for the study of details of the vascular anatomy.

Background and Aims: There is a demand for a better understanding of the vascular structures around the right colonic area. Although right hemicolectomy with the recent concept of meticulous lymph node dissection is a standardized procedure for malignant diseases among most surgeons, variations in the actual anatomical vascular are not well understood. The aim of the present review was to present a detailed overview of the vascular variation pertinent to the surgery for right colon cancer. Materials and Methods: Medical literature was searched for the articles highlighting the vascular variation relevant to the right colon cancer surgery. Results: Recently, there have been many detailed studies on applied surgical vascular anatomy based on cadaveric dissections, as well as radiological and intraoperative examinations to overcome misconceptions concerning the arterial supply and venous drainage to the right colon. Ileocolic artery and middle colic artery are consistently present in all patients arising from the superior mesenteric artery. Even though the ileocolic artery passes posterior to the superior mesenteric vein in most of the cases, in some cases courses anterior to the superior mesenteric artery. The right colic artery is inconsistently present ranging from 63% to 10% across different studies. Ileocolic vein and middle colic vein is always present, while the right colic vein is absent in 50% of patients. The gastrocolic trunk of Henle is present in 46%–100% patients across many studies with variation in the tributaries ranging from bipodal to tetrapodal. Commonly, it is found that the right colonic veins, including the right colic vein, middle colic vein, and superior right colic vein, share the confluence forming the gastrocolic trunk of Henle in a highly variable frequency and different forms. Conclusion: Understanding the incidence and variations of the vascular anatomy of right side colon is of crucial importance. Failure to recognize the variation during surgery can result in troublesome bleeding especially during minimal invasive surgery.

We present a 65-year-old man who had a significant arteriovenous fistula between the right arteria profunda femoralis and vena profunda femoralis. He had evidence of chronic venous insufficiency and chronic leg ulcers on his right leg, and he had clinical findings of congestive heart failure. An arteriovenous fistula was responsible for all of clinical situation that had been caused by a shotgun wound 15 years ago. Using ultrasonography, after palpating a marked thrill and mass during physical examination, established the diagnosis of arteriovenous fistula. Angiography was performed both to delineate the suspected vascular anatomy and to show the coronary arteries. The patient was operated on and no complication was experienced during or after the procedure. Dramatic improvement was seen in the clinical picture just after surgery, and heart size markedly reduced both on chest X-ray and echocardiographic examination.

Background Persistent primitive trigeminal artery (PPTA) is the most common permanent carotid-basilar anastomosis. Magnetic resonance angiography (MRA) has become the primary non-invasive imaging technique for evaluation of cerebral vascular anatomy and can provide detailed 3D imaging of intracranial vessels. Purpose To evaluate the usefulness of MRA for the detection of PPTA and to re-classify its variations based on the embryologic types of PcomA and its relationship with the basilar artery and its branches. Material and Methods Of the total 7329 patients who underwent MRA at our institution from March 2008 through November 2010, we retrospectively analyzed the MRAs of 24 patients with a PPTA. Special attention was given to defining the relationship of the PPTA and the basilar artery with PcomA and to determine the site of origin, size, and course of the PPTA. The PPTA classification included five types based on their anatomic relationship to the neighboring arteries. Clinical features and associated vascular anomalies are also described. Results Twenty-four (17 women and seven men, 34 ∼ 81 years of age, mean age 59.67 years) of the 7329 patients had a PPTA (0.33 %). Eleven cases (45.8%) were classified as type 1, three (12.5%) as type 2, five (20.8%) as type 3, one (4.2%) as type 4, and four (16.7%) as type 5b. Fifteen PPTAs (62.5%) were located on the left side and nine were located (37.5%) on the right side. The basilar artery proximal to the insertion of the PPTA showed severe to moderate hypoplasia in 13 cases (54%). Nine intracranial artery aneurysms were detected in seven (29%) of the 24 study patients. Conclusion This study revealed five types of PPTA and necessitates an adjustment of the previous classification of PPTA on the basis of our MRA examinations. A PPTA should be considered by both the clinician and the radiologist who interpret MR angiography.

Abstract Pancreas transplantation is a well-established treatment for patients with complicated diabetes mellitus and advanced renal failure. The most common procedure is simultaneous pancreas-kidney transplantation, in which the pancreas graft is positioned in the right pelvic region and the kidney graft is positioned in the left iliac fossa. Various imaging methods are used for the post-transplantation evaluation of the graft parenchyma and vascular anatomy, as well as for the identification of possible complications. As the number of cases increases, it is fundamental that radiologists understand the surgical procedure and the postoperative anatomy, as well as to recognize the possible postoperative complications and their imaging aspects, with the aim of providing the best guidance in the postoperative management of transplant recipients.

ABSTRACT:Background:Many anomalies and variants in vascular anatomy have been reported in relation to the anterior cerebral artery (ACA). Patients andPatients and Methods:We encountered an apparently novel anomaly in a 30-year-old man admitted for disturbance of consciousness following a traffic accident. Computed tomography revealed an acute subdural hematoma and subarachnoid hemorrhage.Results and conclusions:No vascular abnormalities related to the hemorrhage were detected by conventional angiography, so we concluded that the bleeding was of traumatic origin. Anomalous origin of the ACA was disclosed incidentally, with both A1 segments arising from the right internal carotid artery; no normal A1 segment of the left ACA was visualized. We discuss possible bases for this anomalous origin.

SUMMARY The typical dichlamydeous cyclic Dicotyledon is so organised that the petaloid character of the corolla can be regarded as a function of a certain combination of conditions as regards time and space: time, in so far that the petaloid feature occurs at a definite stage in the series of developmental processes, following, as it does, upon the differentiation of a (usually) uncoloured (i.e. green) calyx; space, in that it is exhibited on the set of radii alternating with the radii of the sepals. Penetrating a little below the surface appearance, we find we can express these same relations in terms of the vascular anatomy as follows. Those floral members (again taking the typical case) which receive as midribs the first set of equidistant bundles to leave the central cylinder show sepaloid characters; those similarly receiving as midrib bundles the outgoing strands on the alternate set of radii exhibit petaloid colouring. It is found that the marginal veins of the sepals of such Dicotyledon types arise in two different ways, less frequently as true lateral veins from the midribs, more often either through the detachment from the central cylinder on the alternate radii of trunk cords which dissociate in due course into a petal midrib and twin bundles which enter the adjacent side of the sepal to right and left, respectively, and become the marginal vein of that side; or through the departure of pairs of separate strands within the limits of the corresponding alternate sectors. In typical monochlamydeous cyclic Dicotyledons radial organisation follows the same scheme as in dichlamydeous types, notwithstanding that the perianth here takes the form of a single whorl of structures. Such monochlamydeous types may be divided into two classes. In the one class only the issuing vascular bundles on the corresponding set of radii enter the perianth members. These bundles become the midribs. They may give off lateral veins at any point or may remain unbranched. In either case the individual member is homologous with the individual sepal and is typically green. In the other class each member receives not only the bundle on its own radius but also half the perianth component proper to the alternate radius on each side, either as separate strands or (in gamophyllous types) as undisjoined components of perianth-stamen trunk cords. The first-mentioned bundle becomes the midrib of the tepal, the two others become marginal veins, the one entering the tepal on the right, the other that on the left. In forms belonging to this class the tepals are typically petaloid. Each may be regarded as the counterpart of one sepal of dichlamydeous types + half the neighbouring petal on either side. This equivalence is not infrequently indicated outwardly by the considerable thickness of the tepal members as compared with that of the sepals and petals of the nearest allied dichlamydeous forms. The accompanying drawings were made by Miss D. F. M. Pertz, to whom I desire to express my grateful thanks.

Restoration of swallowing in a patient with dysphagia due to nondilatable corrosive stricture of esophagus remains a surgical challenge. Organs available for replacement are stomach, jejunum, or colon. Jejunum is useful to replace a small segment, whereas stomach and colon are required for a long-segment replacement. In cases where the stomach is also injured, colon remains the only option. The route of colonic interposition has also been a subject of debate over the years. The choice of the colon as an esophageal substitute results primarily from the unavailability of the stomach. However, given its durability and function, colon interposition keeps elective indications in patients with benign or malignant esophageal disease who are potential candidates for long survival. The choice of the colonic portion used for esophageal reconstruction depends on the required length of the graft, and the encountered colonic vascular anatomy, the last being characterized by the near-invariability of the left colonic vessels, in contrast to the vascular pattern of the right side of the colon. Accordingly, the transverse colon with all or part of the ascending colon is the substitute of choice, positioned in the isoperistaltic direction, and supplied either from the left colic vessels for long grafts or middle colic vessels for shorter grafts. Technical key points are: full mobilization of the entire colon, identication of the main colonic vessels and collaterals, and a prolonged clamping test to ensure the permeability of the chosen nourishing pedicle. Transposition through the posterior mediastinum in the esophageal bed is the shortest one and thereby offers the best functional results. When the esophageal bed is not available, the retrosternal route is the preferred alternative option. The food bolus traveling mainly by gravity makes straightness of the conduit of paramount importance. The proximal anastomosis is a single-layer hand-fashioned endto- end anastomosis to prevent narrowing. When the stomach is available, the distal anastomosis is best performed at the posterior part of the antrum for the reasons of pedicle positioning and reux prevention, and a gastric drainage procedure is added when the esophagus and vagus nerves have been removed. In the other cases, a Roux-en-Y jejunal loop is preferable to prevent bile reux into the colon.To construct a colon interposition graft that is long enough, we examined a procedure in which the colon is transected proximally at the site of the cecum and the right colic artery is transected, in addition to ligation of the middle artery. Here we examined the series of 20 procedures for post-corrosive esophageal strictures treated with retrosternal colonic interpositions.

AbstractThe vascular anatomy of the pelvis has in the retro pubic space one the most dangerous artery variations for the surgical approach. The aim of this study was to evaluate arise from obturator artery and its implications. Eleven specimens were bisected pelvic an adult cadaver. The iliac artery and femoral artery were identified and divided in their branches. The anomalous origin was noted in 22.72% with an anastomotic branch between the external iliac or inferior epigastric vessels found in 13.69%. The right side showed a greater variation than left side with 27.27% versus 18.18%. Our data suggest that retro pubic space has critical vascular variations of the obturator artery with many probabilities of the lesions.
