A 30-year-old woman underwent a liver transplantation for metastasis of a carcinoid tumor of the midgut previously resected. Operative manipulation of the liver resulted in arterial hypotension, tachycardia, high pulmonary arterial pressure, oedema of the face and peripheral cyanosis, although the patient was given somatostatin (Modustatine, Clin-Midy) (300 micrograms a hour) prior to the procedure. The improvement of the symptoms was obtained by the increase of somatostatin infusion rate to 750 micrograms a hour associated with dopamine (6 micrograms.kg-1.min-1) and fluid replacement. The diagnosis of carcinoid syndrome is discussed. This unusual observation stresses the difficulty in preventing and/or treating a carcinoid shock. If somatostatin seems to be the treatment of choice of such a syndrome, its role in that case was limited.

Mesenteric ischemia associated with carcinoid tumors often presents with nonspecific abdominal pain and is usually due to mesenteric branch artery occlusion caused by elastic vascular sclerosis. Mesenteric ischemia was defined by the operative findings of cyanosis or infarction. Eleven patients with intraabdominal metastatic carcinoid tumor were evaluated by angiography. Angiographic narrowing and occlusion of multiple peripheral jejunal and ileal intramesenteric branch arteries was present in 3 patients with mesenteric ischemia, but also occurred in 5 of 8 patients without mesenteric ischemia. Other angiographic abnormalities included staining of the primary tumor (5) or metastases (6), tenting of small mesenteric vessels (5), and occlusion of draining mesenteric veins (2). We conclude that in patients with midgut carcinoid tumors, angiographic narrowing and occlusion of peripheral mesenteric arteries most likely represents elastic vascular sclerosis, is indicative of mesenteric invasion of tumor, but correlates poorly with the presence of ischemia in the subtended bowel. Alternatively, a normal selective arteriogram should exclude mesenteric ischemia as the cause of abnormal pain.

The manifestations of carcinoid heart disease are usually right heart failure due to pulmonary and tricuspid valve disease and sometimes high output failure due to peripheral vasodilation. Recently there has been one case report of progressive central cyanosis due to right to left shunting through a patent foramen ovale. We present a similar case where such a shunt developed and was also complicated by significant valvular disease affecting the left side of the heart.

Current knowledge strongly supports the theory that the carcinoid spectrum reflects the clinical signs of production, by a carcinoid tumor or by metastatic lesions, of one or more humoral substances. Serotonin, the kinins, histamine (and perhaps other amines), adrenocorticotropic hormone and additional hormones are manufactured by these tumors. Elevated concentrations of serotonin, the kinins and histamine have been found in patients with the carcinoid syndrome, which includes right-sided valvular heart disease, peripheral vasomotor disturbances, bronchoconstriction, borborygmi and an unusual type of cyanosis.

The aim of this study was to assess (1) the incidence of patent foramen ovale (PFO) in carcinoid syndrome (CS) and (2) the feasibility of percutaneous closure procedure in selected patients with CS. One hundred eight patients were prospectively studied: 54 with CS and an age- and gender-matched control group. All patients underwent conventional and contrast echocardiography. Patients with clinical signs of dyspnea (New York Heart Association class > or =III), cyanosis, carcinoid heart disease (CHD), and severe PFO were referred for the percutaneous closure of PFO. The prevalence of PFO was 41% in patients with CS and 22% in the control group (p = 0.03) and was significantly higher in patients with CHD (59%, p = 0.009). Four patients (14% of those with CHD) were referred for the percutaneous closure of PFO, and 3 patients ultimately underwent PFO closure (using Amplatzer septal occluders). At 6-month follow-up, New York Heart Association class was improved in all patients, as well as arterial blood gas results (p = 0.04) and 6-minute walking distance (p = 0.03), but all patients presented residual right-to-left shunts. In conclusion, this prospective study demonstrates that in patients with CHD, the prevalence of PFO is high and that percutaneous closure of PFO is feasible, with a reduction in symptoms but with residual shunting.
