BACKGROUND: An aneurysm of the superior mesenteric artery (SMA) with a diameter of 2.2 cm was found incidentally on an ultrasound (US) examination in a 26-year-old woman. The only known risk factor was an intracranial aneurysm that was found on her grandmother's autopsy. Based on pregnancy planning and the current literature, endovascular management with a covered stent was proposed. CASE REPORT: Self-expandable, covered stent (Bard, Fluency(®)) was implanted using a single transfemoral approach...

Visceral artery revascularisation through a retroperitoneal approach provides an infrequent yet viable, alternative means of managing mesenteric ischaemia in patients with previous abdominal operations. We present a unique case implementing this surgical approach in a 55-year-old man in which we performed a retroperitoneal aortobifemoral bypass with concomitant retrograde jump graft from the aortic prosthesis to the superior mesenteric artery (SMA) for bilateral lower extremity rest pain and chronic mesenteric ischaemia...

Visceral artery aneurysm (VAA) is very rare among vascular pathologies. Incidence reported in autopsy series and angiographic studies varies between 0.1% and 0.2%. Most cases are asymptomatic and are diagnosed as result of complications, or incidentally, when imaging is performed for another reason. Three percent of VAAs are superior mesenteric artery (SMA) terminal branch aneurysms. Intra- and/or extraperitoneal bleeding due to ruptured aneurysm is life-threatening condition and requires emergent intervention...

t Superior Mesenteric Artery (SMA) syndrome is an uncommon condition caused by mechanical obstruction of the distal third of the duodenum between the superior mesenteric artery and the abdominal aorta. SMA syndrome is associated with both operative and non-operative corrections of scoliosis, as well as anorexia nervosa, severe weight loss, tumors, burns, and other traumas.[1-4] We report an unusual case of SMA syndrome following corrective surgery for scoliosis in which post-operative gastric distension caused duodenal compression that subsequently resolved with gastric decompression, as opposed to the conventional, reverse series of events in which SMA syndrome causes the gastric dilatation...

PURPOSE: Surgeon-modification of commercially available aortic stent grafts represents a salvage option to treat complex aortic pathologies in high-risk patients. TECHNIQUE: A 68-year old male was referred in our hospital with a contained rupture of the visceral aorta. The patient was previously treated with an infrarenal tube graft 16 years earlier as well as with a Crawford procedure with island patch of the coeliac trunk (TC) and the superior mesenteric artery (SMA) and bypasses to both renal arteries 6 years prior to admission...

BACKGROUND: With the introduction of complete mesocolic excision (CME) and the application of laparoscopic technique, surgery for colon cancer has become more standardized and the curative effect has improved [1]. The key points in laparoscopic right hemicolectomy are high ligation of main vessels and root dissection of lymph nodes. The wide range of variations in vascular architecture and intraoperative bleeding are common causes of prolonged surgical time, wound hemorrhage, and even transfer to the opening operation...

OBJECTIVE: To assess the significance of the angle between superior mesenteric artery (SMA) and distal aorta in spontaneous isolated superior mesenteric artery dissection (SISMAD) by clinical and biomechanical analyses. METHODS: 37 patients with SISMAD (one asymptomatic) and 148 controls (1:4 matched for age [mean, 50.2 years], gender [92% male], and body mass index; and being ruled out for arterial disease) underwent aortic computed tomography angiography. SMA-distal aorta angle, measured on sagittal plane, was compared along with baseline characteristics (body mass index, smoking history and comorbidities) between groups; and assessed as tool to evaluate SISMAD risk after stratification into four angle-interval categories...

INTRODUCTION: Superior mesenteric artery (SMA) syndrome also known as Wilkie's syndrome is a rare condition caused by the entrapment of the third part of the duodenum between the aorta and the SMA. The incidence of Wilkie's syndrome range between 0.013% and 0.3%. The normal angle between the aorta and SMA has been described to range between 38° and 65°, whereas in Wilkie's syndrome this angle is reduced to less than 20° causing gastric outlet obstruction. CASE PRESENTATION: We report a case of a previously diagnosed 43 year-old male with SMA syndrome, whom had been conservatively managed for 5-years for recurrent admissions with symptoms of gastric outlet obstruction...

INTRODUCTION: Rupture of superior mesenteric artery aneurysm (SMAA) is a very rare and life-threatening condition, presenting with acute intraabdominal hemorrhage. CASE: The patient was hospitalized upon complaint of nonspecific severe abdominal pain. Diagnosis of SMAA was established by abdominal Doppler ultrasound that showed a pseudo-aneurysmal lesion with size of 76 × 47 mm at the superior mesenteric main branch. Endovascular stenting was not performed because of the wide neck in the segment of the jejunal branches from SMA and the risk of branch loss during treatment...

INTRODUCTION The superior mesenteric artery (SMA) syndrome, or Wilkie's syndrome, is a rare cause of postprandial epigastric pain, vomiting and weight loss caused by compression of the third part of the duodenum as it passes beneath the proximal superior mesenteric artery. The syndrome may be precipitated by sudden weight loss secondary to other pathologies, such as trauma, malignancy or eating disorders. Diagnosis is confirmed by angiography, which reveals a reduced aorto-SMA angle and distance, and contrast studies showing duodenal obstruction...

INTRODUCTION: Situs inversus viscerum, a congenital condition in which the visceral organs are a mirror image of their normal physiological positions, could be total or partial. Persistent descending mesocolon (PDM) is a congenital anomaly that is asymptomatic because of its short length. PDM causing intestinal obstruction is a known clinical complication. PRESENTATION OF CASE: A 74-year-old woman presented with pneumaturia and enteruria for two months, and recurrent cystitis for a month...

PURPOSE: To establish a method by which angiography of the inferior mesenteric artery (IMA) can be performed smoothly, we investigated the relative locations of the coeliac trunk (CT), superior mesenteric artery (SMA), IMA, and left renal artery (LtRA). METHODS: From a total of 60 cadavers, 32 cadavers with few arteriosclerotic lesions and little vascular tortuosity were selected for the study. The abdominal aorta (Ao) were removed and incised on both lateral side, along the vertical axis and transected into the ventral and dorsal sides...

Hepatobiliopancreatic surgery is challenging becouse of the complexity of resections and reconstructions and variability of vascular anatomy. The arterial vascularization of the liver is susteined by the common hepatic artery (CHA) that originates from the celiac trunk (CT). The CHA bifurcates into the gastroduodenal artery (GDA) and proper hepatic artery (PHA) 0.5-1 cm medial to the common bile duct (CBD), and the PHA bifurcates into a right and a left branch at hepatic hilum. The most frequent variants are the right hepatic artery (RHA) from the superior mesenteric artery (SMA), the left hepatic artery (LHA) from the left gastric artery (LGA) or a combination of these two variants...

BACKGROUND: Pseudomyxoma peritonei (PMP) is a rare carcinomatosis limited to the peritoneal cavity, mainly supplied by the superior mesenteric artery (SMA). The only curative treatment is cytoreductive surgery (CRS) associated with hyperthermic intraperitoneal chemotherapy. This study aimed to evaluate the ability of blood flow volume (BFV) recorded in the SMA using Doppler ultrasonography pre-operatively to predict the extent and resectability of the disease and post-operatively to assess clinical outcome...
