BACKGROUND: The medial approach in laparoscopic splenic flexure mobilization is based on the entrance to the lesser sac just above the ventral edge of the pancreas (VEOP). The artery of Moskowitz runs through the base of the mesocolon, just above the VEOP. The aim of this study was to assess the incidence of the artery of Moskowitz, its route and its distance from the VEOP. METHODS: We performed a cadaveric study on 27 human cadavers. The vascular arcades of the splenic flexure were dissected, the number of vascular arches, and the origin and localization of its terminal anastomosis were recorded...

BACKGROUND: There are 2 interpretations of Riolan's arch: (1) Riolan's arch is identical to a central part of the marginal artery (MA), connecting the superior (SMA) and the inferior mesenteric (IMA) arteries; and (2) Riolan's arch represents a rare artery, connecting the SMA and the IMA. The current review aims to emphasize the clinical importance of the colon's vasculature and to show the feasibility of abolishing the terms "Riolan's arch" and "meandering mesenteric artery." METHODS: A literature survey was performed...

The aim of this study was to describe all levels of the intermesenteric communications because of their importance in vascular diseases of the colon. The connections of superior and inferior mesenteric networks are very important in cases of acute or chronic obstruction to prevent ischemia and necrosis. Angiograms of mesenteric arteries were studied (40), cadaverous large intestine samples with mesentery and feeding vessels were dissected (36) or injected with India ink solution (24) or methylmetacrylate Mercox (41)...

BACKGROUND: The aim of this study was to evaluate the late results in adult patients who underwent surgery of the abdominal aorta as children. METHODS: During a 17-year period, eight children underwent surgery for lesions of the abdominal aorta. There were 6 boys and 2 girls, with an average age of 10 years. The presenting symptom that led to diagnosis of abdominal aortic lesions was hypertension in five cases and lower-limb claudication in three. The underlying disease was middle aortic syndrome in three cases, infrarenal aortic hypoplasia in two, infrarenal aortic aneurysm in two, and Takayasu's disease in one...

Arterial vascularization of the gastrointestinal tract is a three-level system composed of the coeliac trunk, and both superior and inferior mesenteric arteries. The three levels are joined together via arterial trunk anastomoses such as the so-called and well-known Riolan arcade or supramarginal arcade. The aim of this study was to review the embryology of the digestive arteries in order to understand the anatomic variations, the development of the arterial trunk anastomoses and the potential collateral circulation in the case of obstruction of one or several arterial trunks...

OBJECTIVE: The purpose of this study was to describe the radiologic findings of the collateral venous pathways in the transverse mesocolon and the greater omentum associated with pancreatic diseases and to correlate these venous pathways and the accompanying arterial anatomy. CONCLUSION: The collateral pathway in the transverse mesocolon consists of the inferior mesenteric vein, left transverse colic vein, marginal vein of the transverse colon, and middle colic vein...

INTRODUCTION: The arterial communication between the superior and inferior mesenteric arteries is important in surgery of the colon and aorta. METHODS: The anastomosis between the median colic artery (ACM) and the superior colic artery (AMS) was studied on 52 cadavers (32 female, 20 male). The length of the artery was measured using a flexible scale, and its diameter was determined at three different locations (origin, middle, end). RESULTS: The median lengths of the arteries were: 6...

The authors study the behaviour of the middle colic, left colic superior, middle and inferior and the first sigmoidal arteries in the territory of the terminal portion of the transverse colon, the left colonic flexure and the descending colon. The study was carried out on 1200 angiographies of the superior and inferior mesenteric aa. and on 150 anatomical specimens, surgically extirpated in the course of left emicolectomy operations. Contrary to what is believed by most authors, the left flexure is a colonic tract very well supplied by blood while the descending colon results to be poorly supplied, being served only by one artery (the left sup...

We report a successful result of treatment for a ruptured thoracoabdominal aortic aneurysm with aortitis syndrome. A 43-year-old male suffered sudden low back pain, that was diagnosed as a ruptured thoracoabdominal aortic aneurysm based on abdominal computed tomography. Preoperative angiography revealed a thoracoabdominal aortic aneurysm with occlusion of the superior mesenteric artery, and well developed Riolan's archade. The aneurysm was replaced by a prosthetic graft with partial femoro-femoral bypass in conjunction with selective cold perfusion for the visceral arteries...

The Riolan's anastomosis arch is discussed on the basis of colon vessel constructions in 162 operations of the colonic interposition for esophageal substitution, and the materials reported in some journals. The Riolan's arch is not the marginal vessels of the flexura lienalis, because of its lower incidence (< 10%). We believe that the integrity of the arch is not responsible for the blood supply of the colon.

One case of multiple occlusions and stenoses of the abdominal aortic archs with development of Riolan's collateral in a young patient with hypertension is described. In the literature some cases are pointet out, which clinically resemble our patient and where the aetiology is not clarified. -- In the discussion about the aetiology of this vascular anomaly a developmental anomaly and mechanical compression by the crura diaphragmatica are named. We think, that an unspecific arteriitis similar to the in Japan well known Tacaysau-Aortitis must also be discussed...
