Seventeen patients with familial hypercholesterolemia (9 males and 8 females) were treated with 1000 mg deoxycholic acid or placebo daily during 2 weeks in a double-blind, randomised cross-over fashion. A wash-out period was held between the two periods of therapy. Clinical chemical parameters, lipoprotein cholesterol and apolipoproteins were measured before and after each period. Low density lipoprotein cholesterol was reduced by 7.5% and LDL-apo B by 5.6%. Only the latter change was significantly different from the corresponding changes in the placebo period (P less than 0.05). High density lipoprotein cholesterol did not change. Apolipoprotein A-I decreased by 4% (P less than 0.05). Apolipoprotein A-II did not change. While taking deoxycholic acid, most patients had abdominal discomfort and/or diarrhoea. The serum transaminases increased in 7 patients taking this drug and in none while taking a placebo. We conclude that this therapy is of little value in hypercholesterolemic patients.

Celiac artery aneurysms were encountered in nine patients, ranging in age from 39 to 76 years, at the University of Michigan Medical Center between 1961 and 1983. Developmental defects and atherosclerosis were etiologic factors in six cases. Four patients were without symptoms, whereas five experienced abdominal pain, including one with a ruptured aneurysm. Eight patients were subjected to surgical treatment; no deaths occurred and symptoms were resolved in all patients. A literature review of 108 celiac artery aneurysms revealed two distinct subgroups. Among 60 celiac artery aneurysms encountered before 1950, representing the historic era, 40% were infectious (usually luetic), 7% were traumatic, and 52% were of undetermined cause. Most were symptomatic, 87% ruptured, and 95% were diagnosed at postmortem examination. The contemporary era since 1950 consisted of 48 cases, including nine in the Michigan experience. Congenital or developmental medial defects of the arterial wall and atherosclerosis were the most common causes of aneurysms. Most aneurysms in the contemporary period were either asymptomatic or accompanied by vague abdominal discomfort. Rupture affected 13% of those aneurysms. Operative therapy was successfully undertaken in 91% of 43 patients during the contemporary era, including eight in the present series.

A 53-year-old woman presented with abdominal discomfort and was diagnosed using ultrasonography to have an abdominal aortic aneurysm. Aortography revealed a saccular aneurysm 4 cm in diameter of the infrarenal aorta with a 'string of beads' appearance. The renal and other visceral arteries appeared to be normal. Resection and graft replacement was performed because of the possibility of rupture. Histological examination of the specimen revealed the most common type of fibromuscular dysplasia, namely medial fibroplasia. Fibromuscular dysplasia should be considered as a potential cause of abdominal aortic aneurysm in female patients with no atherosclerosis risk factors.

Anorexia is common in patients with chronic kidney disease and is a main contributor to the high prevalence of protein-energy wasting in them. The peritoneal dialysis (PD) procedure may further impair appetite by causing abdominal discomfort and also through the absorption of the osmotic agent and other factors. An increased peritoneal solute transport rate has been linked to protein-energy wasting and also to the malnutrition, inflammation, and atherosclerosis syndrome, which has been associated to poor appetite and plays a role in most premature deaths in these patients. The pathogenesis of these associations is unclear. In this review, we discuss the effect of PD, in particular, PD solutions, inflammation, and increased peritoneal solute transport rate, on appetite. We also describe strategies to increase appetite in PD patients.

Chronic mesenteric ischemia (CMI) is the most common vascular disorder involving the intestines, however it is unusual in clinical practice. The redundancy of the visceral circulation with multiple interconnections between the superior mesenteric artery (SMA) and the inferior mesenteric artery (IMA) is the most likely explanation for the infrequent occurrence of CMI in clinical practice. Atherosclerosis is by the far the most common etiology of CMI. The increased utilization of diagnostic abdominal cross-sectional imaging has increased the recognition of atherosclerotic mesenteric stenoses. CMI is a clinical diagnosis, based upon symptoms and consistent anatomic findings. The classic setting for CMI is a female patient presenting with post-prandial abdominal discomfort that results in significant weight loss. Endovascular therapy with stenting has become the most common method chosen for revascularization having replaced open surgery with its associated morbidity and mortality.

Lumbar chemical sympathectomy has been performed using fluoroscopic guidance for needle positioning. An 84 year old woman with atherosclerosis obliterans was referred to the pain clinic for intractable cold allodynia of her right foot. A thermogram showed decreased temperature of both feet compared with temperatures above both ankles. The patient agreed to undergo lumbar chemical sympathectomy using fluoroscopy after being informed of the associated risks of nerve injury, hemorrhage, infection, transient back pain, and transient hypotension. During the procedure and three hours afterward, no abnormal signs or symptoms were found except an increase in right leg temperature. The patient was ambulatory after the procedure. However, one day after undergoing lumbar chemical sympathectomy, she visited our emergency department for abdominal discomfort and postural dizziness. Her blood pressure was 80/50 mmHg, and flank tenderness was noted. Retroperitoneal hemorrhage from the second right lumbar segmental artery was shown on computed tomography and angiography. Vital signs were stabilized immediately after embolization into the right lumbar segmental artery.

A 7 yr old male beagle was examined because of lethargy, anorexia, and cranial abdominal discomfort. Significant clinicopathologic abnormalities included severe liver enzyme elevations and hypercholesterolemia. Abdominal imaging identified vascular compromise of the left lateral liver lobe and a gallbladder mucocele. Following liver lobectomy and cholecystectomy, the dog's clinical signs resolved, and liver enzymes substantially improved. Diffuse hepatocellular infarction and necrosis secondary to multifocal atherosclerosis was present on histopathology of the liver. Hypothyroidism was subsequently diagnosed. Restoration of euthyroidism with oral levothyroxine therapy resolved the remaining liver enzyme elevations and hypercholesterolemia. To the author's knowledge, this is the first case report of hypothyroidism resulting in a clinically apparent and resolvable acute hepatopathy due to atherosclerosis. Clinicians should include atherosclerosis as a differential diagnosis for dogs with an acute hepatopathy and investigate dogs for hypothyroidism if atherosclerosis is diagnosed on liver biopsy.
