SUPERIOR MESENTERIC ARTERY SYNDROME: CLINICAL, ENDOSCOPICAL AND RADIOLOGICAL CORRELATIONS ACCORDING TO A SINGLE-CENTER EXPERIENCE
2015
Background and aim: The superior mesenteric artery (SMA) syndrome is a rare entity presenting with upper gastrointestinal tract obstruction and weight loss, due to the compression of the third part of duodenum between the aorta and the SMA. Studies to determine the optimal methods of diagnosis and treatment are essential. This study aims to analyze the clinical presentation, the doagnosis and the management of this syndrome. Material and medthods: Over a 2-year (2013-2014), 8 cases of SMA syndrome (out of 2074 esophago-gastro-duodenoscopies, EGDS) were initially suspected through EGDS. Therefore, these patients performed computed tomography (CT) scan to confirm the diagnosis. Once the diagn…
CT-Angiographie versus intraarterielle DSA bei Bauchaortenaneurysmen
1996
PURPOSE To evaluate if CT angiography is able to image all features necessary for the preoperative planning of abdominal aortic aneurysms (accessory renal arteries, stenoses or occlusions of renal and iliac arteries, patency of inferior mesenteric artery). METHODS CT angiography and DSA were performed on 27 patients with abdominal aortic aneurysms. CT angiography was performed using a protocol that covered the abdominal aorta and the pelvic arteries with a single spiral acquisition (contrast dose: 150 ml, collimation: 5 mm, table feed: 7.5 mm/s, increment of reconstruction: 2 mm). Maximum intensity projections (MIP) and axial scans were compared with the results of intraarterial DSA. RESULT…
Pancreaticoduodenal arteries aneurysms: Evaluation of frequency and association with celiac artery stenosis due to compression by median arcuate liga…
2019
The aim of the study is to evaluate the prevalence of pancreaticoduodenal arteries (PDA) aneurysms in a large population, and to define possible correlations with celiac artery stenosis due to compression by the median arcuate ligament. Radiological reports of abdominal contrast-enhanced CT scans of 18,180 patients were scrutinized to identify patients with true PDA aneurysms. Two abdominal radiologists classified the aneurysms according to size, location and morphology and scored the presence of celiac artery stenosis due to either median arcuate ligament compression or atherosclerotic disease. Eleven true PDA aneurysms were identified in 10 patients. Nine out of 10 patients had stenosis o…
Chimney and Periscope Grafts Observed Over 2 Years After Their Use to Revascularize 169 Renovisceral Branches in 77 Patients With Complex Aortic Aneu…
2013
Purpose: To evaluate the performance of periscope and/or chimney grafts (CPGs) in the endovascular treatment of pararenal or thoracoabdominal aneurysms using off-the-shelf devices. Methods: Between February 2002 and August 2012, 77 consecutive patients (62 men; mean age 7369 years) suffering from pararenal aortic (n¼55), thoracoabdominal (n¼16), or arch to visceral artery aneurysms (n¼6) were treated with aortic stent-graft implantation requiring chimney and/or periscope grafts to maintain side branch perfusion. CPGs were planned in advance and were not used as bailout. A standardized follow-up protocol including computed tomographic angiography, laboratory testing, and clinical examination…
CT imaging findings of abdominopelvic vascular compression syndromes: what the radiologist needs to know.
2020
AbstractAbdominopelvic vascular compression syndromes include a variety of uncommon conditions characterized by either extrinsic compression of blood vessels by adjacent anatomical structures (i.e., median arcuate ligament syndrome, nutcracker syndrome, May-Thurner syndrome) or compression of hollow viscera by adjacent vessels (i.e., superior mesenteric artery syndrome, ureteropelvic junction obstruction, ureteral vascular compression syndromes, portal biliopathy). These syndromes can be unexpectedly diagnosed even in asymptomatic patients and the predisposing anatomic conditions can be incidentally discovered on imaging examinations performed for other indications, or they can manifest wit…

Surgical anatomy applied to transperitoneal approaches of the abdominal aorta and visceral trunks. Dynamic article.
2020
Access to the abdominal aorta and its visceral trunks is possible through several approaches. Dissections of five cadavers performed during three National Surgical Anatomy courses applied to Aorta, Hepatobiliopancreatic and Digestive Surgery. Videos and pictures were taken throughout the dissections and showed different abdominal aorta approaches. Abdominal aorta and visceral trunks approaches: longitudinal inframesocolic access, supraceliac clamping, celiac trunk dissection, superior mesenteric artery approaches (retroperitoneal after Kocher menoeuvre, supramesocolic or inframesocolic), Cattell-Braasch manoeuvre and mattox manoeuvre: retrorenal and prerenal. Correct knowledge of the intraa…
Isolated dissection of the superior mesenteric artery: a case report and literature review
2014
Isolated dissection of the superior mesenteric artery is rare; it is predominantly observed in men with the highest incidence in those over 40 years old. Contrast-enhanced multi-detector computed tomography is considered essential for the diagnosis, therapeutic management and follow-up. The therapeutic approach ranges from conservative medical treatment to surgery or endovascular stent placement, but there are, to date, no approved guidelines. We report the case of a 68-year old man who entered our Emergency Department just for mild abdominal pain, which later proved to be due to acute dissection of the superior mesenteric artery.
Das »Nußknacker-Syndrom« der Vena renalis (Arteria-mesenterica-superior-Syndrom) als Ursache gastrointestinaler Beschwerden
2008
History and clinical findings Since the age of 19 a now 22-year-old man had complained of intermittent abdominal pain, irregular stools and paroxysmal tachycardia. The only preceding illness had been a single episode of iron-deficiency anemia. A laparoscopy, done 8 months after the onset of symptoms, had revealed an inflamed Meckel's diverticulum which was surgically removed. After transient improvement the symptoms recurred 5 months postoperatively. On admission to clarify the cause of the symptoms he had discrete abdominal pain on pressure, but physical examination was otherwise unremarkable. Investigations Routine biochemical tests and endoscopy were normal. Abdominal computed tomography…
Superior Mesenteric Artery Syndrome: Clinical, Endoscopic, and Radiological Findings.
2018
Background. The superior mesenteric artery (SMA) syndrome is a rare entity presenting with upper gastrointestinal tract obstruction and weight loss. Studies to determine the optimal methods of diagnosis and treatment are required. Aims and Methods. This study aims at analyzing the clinical presentation, diagnosis, and management of SMA syndrome. Ten cases of SMA syndrome out of 2074 esophagogastroduodenoscopies were suspected. A contrast-enhanced computed tomography (CECT) scan was performed to confirm the diagnosis. After, a gastroenterologist and a nutritionist personalized the therapy. Furthermore, we compared the demographical, clinical, endoscopic, and radiological parameters of these …
