It has been shown previously that the amplitudes of the harmonic components of the pulse spectrum vary in specific patterns when the arteries leading to different organs are ligated, with the variations in the harmonics being linearly additive. Since ligation can be regarded as a vast increase in organ resistance, ...

Isolated dissection of the superior mesenteric artery is an uncommon event, but many new cases have been reported recently, reflecting the progress of imaging and suggesting that this pathology is not as rare as previously thought. Here we report a case of superior mesenteric artery dissection where we performed, after ...

Visceral arterial aneurysm is an uncommon form of vascular disease that has a significant potential for rupture or erosion into an adjacent viscera, resulting in life-threatening hemorrhage. Superior mesenteric artery (SMA) aneurysms are especially rare, comprising only 5-8% of all visceral arterial aneurysms. Traditionally, the most common treatment for SMA ...

Acute Mesenteric Ischaemia (AMI) is an uncommon vascular emergency where the diagnosis is often difficult and overlooked and delay in diagnosis results in a grave outcome. Although extravascular events like intussusception, volvulus, strangulated hernia and adhesive obstruction in neglected cases can result intestinal gangrene, this contribution will be limited to ...

Visceral artery aneurysms are found in only 0.2% of the general population. Among these, aneurysms of the superior mesenteric artery (SMA) are very unusual and account for only 5.5 % to 8 %. Risk of rupture or embolization is the impetus for their definitive treatment and this should be performed ...

The mRNA levels for the three alpha1-adrenoceptor subtypes, alpha1A, alpha1B, and alpha1D, were quantified by real-time RT-PCR in arteries from Wistar rats. The alpha1D-adrenoceptor was prominent in both aorta (79.0%) and mesenteric artery (68.7%), alpha1A predominated in tail (61.7%) and small mesenteric artery (73.3%), and both alpha1A- and alpha1D-subtypes were ...

Experimental hyperglycemia produces a marked hypertrophic response in rat mesenteric arteries, accompanied by activation of Na/H exchange (NHE) in medial smooth muscle. This study asked if other vascular beds are similarly affected by examining the hypertrophic and NHE response of the basilar artery. Sections of mesenteric and basilar arteries from ...

Hepato-pancreaticoduodenectomy was performed for common bile duct carcinoma associated with celiac axis stenosis. To secure arterial blood flow to the upper abdominal organs, we preserved the anterior arcade in the pancreas head acting as a collateral pathway between the superior mesenteric artery and the celiac artery. This is another valid ...

Mycotic aneurysms are an important cause of morbidity and mortality in endocarditis despite advanced antibiotic therapy. Visceral artery aneurysms are uncommon and usually remain clinically silent until rupture. We now report a case of successful surgical treatment of a superior mesenteric mycotic aneurysm of the superior mesenteric artery, followed by ...

Aortic thrombosis rarely occurs without severe atherosclerosis, aneurysm, or cardiosurgical or traumatic state. Arterial thrombosis is commonly related to an inherited and/or acquired hypercoagulable state. A 50-year-old woman presented with diffuse abdominal pain. One day after her admission, she experienced bloody stools. Computed tomography showed multiple extensive thromboses in the ...

BACKGROUND/PURPOSE: Colonic atresia occurs in 1:20,000 live births, offering a neonatal surgical challenge. Prenatal expression of fibroblast growth factor 10 (Fgf10), acting through fibroblast growth factor receptor 2b (Fgfr2b), is critical to the normal development of the colon. Invalidation of the Fgf10 pathway results in colonic atresia, inherited in an ...

Phenylpropanolamine (dl-norephedrine) was one of the most widely used therapeutic agents to act on the sympathetic nervous system. Because of concerns regarding incidents of stroke, its use as a nasal decongestant was discontinued. Although considered an alpha1-adrenergic agonist, the vascular adrenergic pharmacology of phenylpropanolamine was not fully characterized. Unlike most ...

We successfully treated a case of a 65-year-old female with an abdominal aortic aneurysm coexisting with an atypical coarctation of thoracoabdominal aorta and celiac axis and superior mesenteric artery occlusion. A dilated inferior mesenteric artery was supplying the celiac artery and superior mesenteric artery regions. The patient also had mitral ...

In recent years, partial laryngectomy and partial reconstruction are increasingly intended for conservation of functions of phonation and swallowing. In partial reconstruction, it is important to comprehend morphological characteristics of the blood vessels distributed in the larynx, but there have been only few reports discussing detailed information about them. Previous ...

Evaluation of the technical practicability of the acute results and complications with transbrachial catheter interventions. Retrospective investigation of 156 catheter interventions with 147 patients within the period of 4/2000 to 12/2003. Target vessel, technical success, complications and in- or out-patient' practicability received special consideration. The intervention was technically successful in ...

Celiac trunk or superior mesenteric artery stenosis are usually innocuous conditions. In such patients, arterial blood supply to the stomach, spleen, liver and bowel is sustained through extraordinarily well-developed pathways through the pancreas. If division of these collateral vessels is necessary during a surgical procedure such as pancreaticoduodenectomy, life-threatening celiac ...

Destruction of the vascularisation of the olfactory structures during fronto-orbital surgical approaches to the sellar region may result in anosmia as a complication. The goal of this study was to describe the sources of blood supply to the proximal olfactory tract and the macroscopic distribution of these vessels. 20 human ...

We present a case of a 62-year-old man with known coeliac disease who was admitted for investigation of abdominal pain and weight loss. He underwent multiple biochemical, haematological, radiological and endoscopic investigations (which were all normal) and also had a normal laparoscopy. Abdominal computerized tomography angiography, however, suggested significant mesenteric ...

Rectal cancer and cardiovascular disease are both commoner in the elderly and may coexist. In some severe arteriopaths the blood supply to the lower limbs may be a collateral circulation from the inferior mesenteric artery. Patients with aorto-iliac occlusion or severe stenosis may have collaterals from the inferior mesenteric artery ...

Previous studies suggest that epoxyeicosatrienoic acids (EETs) are vasodilators of the mesenteric artery; however, the production and regulation of EETs in the mesenteric artery remain unclear. The present study was designed 1) to determine which epoxygenase isoform may contribute to formation of EETs in mesenteric arteries and 2) to determine ...

We found a case in which inferior mesenteric artery and the common hepatic artery arose from the superior mesenteric artery, forming the common hepatomesenteric trunk, during a routine dissection carried out at Iwate Medical University in 2002. This variation is rare, but can be embryonically explained. A change in the ...

A 76-year-old woman with abdominal pain and diarrhoea developed ascites that did not respond to treatment. There were no signs of liver damage. Abdominal ultrasonography with colour Doppler revealed an arterial-like flow in the enlarged splenic vein. Using selective mesenteric arteriography, we were able to diagnose a shunt between the ...
