1A). Given his abdominal
discomfort and an abnormal hepatic Doppler study, he proceeded to an abdominal angiogram, which revealed a severe stenosis between the donor and recipient cava with minimal hepatic venous (HV) outflow (Fig. 2). The intercaval anastomosis was crossed with a guide wire and a balloon dilatation to 8 mm was performed resulting in markedly improved hepatic venous outflow (Fig. 3). Two months later the patient’s dyspnea had completely resolved and PaO2 on room air had risen to 89 mmHg (Fig. 4). A repeat 99mTcMAA lung perfusion scan (Fig. 1B) revealed no significant brain uptake and thus confirmed resolution of HPS. To our knowledge, the recurrence of HPS in an adult NCPH patient post-OLT has not been reported. HPS has been reported to recur posttransplantation in the context of serious graft disease or cirrhosis. In our case it redeveloped in the absence of any evidence www.selleckchem.com/products/Bortezomib.html of graft
damage, suggesting that the hemodynamic alterations associated with impairment RG7204 cost of hepatic outflow were solely responsible. While HV outlet obstruction is an unusual cause of HPS, the syndrome has been described in individuals with IVC obstruction with amelioration of hypoxia on restoration of flow. Why the disease occurs in only a minority of cirrhosis patients and only occasionally in patients with NCPH is uncertain. However, this presumably reflects an underlying “susceptibility” in those who develop the syndrome which is absent in most patients. What factors govern this susceptibility is as yet unknown. The redevelopment of clinically significant
HPS in our patient many years posttransplant after apparent complete resolution of the syndrome shows that this susceptibility 上海皓元 persists for life and that it cannot be related to liver disease per se or some host susceptibility factor within the liver. “
“A 62-year-old male was referred to our department after a segmental resection of the small bowel due to a spontaneous perforation 3 months earlier. He complained of anorexia, fever and abdominal pain. The patient had lost 10 kg of body mass within the last 3 months. He had no history of celiac disease or chronic diarrhea. On admission, the patient was in poor general condition with severe cachexia. The abdomen was distended and a large firm mass was palpable in the left midabdomen. The peripheral lymph nodes were not enlarged. Laboratory tests revealed pancytopenia and hypoalbuminemia. Liver function tests, serum lactate dehydrogenase and β2-microglobulin were mildly elevated. Computed tomography (CT) scan of the abdomen showed multiple cystic lesions with fat-fluid levels within the mesentery (arrows) and a hypotrophic spleen (Figure 1A). Magnetic resonance imaging (MRI) demonstrated several intra-abdominal cysts (arrows) along the mesentery (Figure 1B) and multiple bone lesions suggesting metastases. On surgical exploration, the mesenteric lymph nodes were cystic and 1–10 cm in size (Figure 2).
