Partial splenic artery embolization(PSE) has been demonstrated to effectively increase hematologic indices in cirrhotic patients with splenomegaly. This is particularly valuable amongst those cirrhotic patients who are not viable candidates for splenectomy. Although PSE was originally developed decades ago, it has recently received increased attention. Presently, PSE is being utilized to address a number of clinical concerns in the setting of cirrhosis, including: decreased hematologic indices, portal hypertension and its associated sequela, and splenic artery steal syndrome. Following PSE patients demonstrate significant increases in platelets and leukocytes. Though progressive decline of hematologic indices occur following PSE, they remain improved as compared to pre-procedural values over long-term follow-up. PSE, however, is not without risk and complications of the procedure may occur. The most common complication of PSE is post-embolization syndrome, which involves a constellation of symptoms including fever, pain, and nausea/vomiting. The rate of complications has been shown to increase as the percent of total splenic volume embolized increases. The purpose of this review is to explore the current literature in re-gards to PSE in cirrhotic patients and to highlight their techniques, and statistically summarize their results and associated complications.展开更多

METHODS： Coeliac disease （CD） patients were divided into two groups. Group Ⅰ ： uncomplicated CD （n = 14） and RCD type Ⅰ （n = 10）. Group Ⅱ ： RCD type Ⅱ （n = 15） and EATL （n = 7）. RESULTS： Both groups showed classic signs of CD on CT. Intussusception was seen in 1 patient in group Ⅰ vs 5 in group Ⅱ （P = 0.06）. Lymphadenopathy was seen in 5 patients in group Ⅱ vs no patients in group Ⅰ （P = 0.01）. Increased number of small mesenteric vessels was noted in 20 patients in group Ⅰ vs Ⅱ in group 11 （P = 0.02）. Eleven patients （50%） in group 11 had a splenic volume 〈 122 cm^3 vs 4 in group Ⅰ （14%）, 10 patients in group Ⅰ had a splenic volume 〉 196 cm^3 （66.7%） vs 5 in group Ⅱ （33.3%） P = 0.028. CONCLUSION： CT scan is a useful tool in discriminating between CD and （Pre） EATL. RCD Ⅱ and EATL showed more bowel wall thickening, lymphadenopathy and intussusception, less increase in number of small mesenteric vessels and a smaller splenic volume compared with CD and RCD Ⅰ.展开更多

Bone marrow biopsy showed an intracapillary infiltration of T-lymphocytes with no evidence of lipid storage disease. Because of a progressive spleen enlargement,splenectomy was performed.Histological examination showed lymphomatous intrasinuses invasion of the spleen. Immunohistochemical investigation revealed the T phenotype of the neoplastic cells:CD45+,CD45RO+, CD3+,CD4-,CD8-,TIAl-.About 50 % of the lymphoid cells expressed CD56 antigen.The diagnosis of hepatosplenic T cell lymphoma was done.The patient was treated with chemotherapy,which induced a complete remission.Eighteen months later,he had a first relapse with increased aspartate aminotransferase,alanine aminotransferase,lactate dehydrogenase, thrombocytopenic purpura and blast in the peripheral blood. In spite of autologous bone marrow transplantation,he died twenty months after the diagnosis.Even in the absence of a mass lesion or lymphoadenopathy,hepatosplenic T- cell lymphoma should be considered in the differential diagnosis of a patient whose clinical course is atypical for acute hepatic dysfunction.展开更多

It leads to splenomegaly which manifests with features of hypersplenism. This results in leucopenia which increases the likelihood of sepsis and prevents treatment with interferon. Thrombocytopenia increases the risk of bleeding including variceal bleeds which make the anemia worse. This study was done to determine the usefulness and safety of partial splenic artery embolization (PSAE) in portal hypertension due to cirrhosis. Methods: Patients with PSAE were identified by using International Classification of Diseases (ICD)-10 coding from medical records and their charts were reviewed retrospectively. 25 patients underwent splenic artery embolization at The Aga Khan University Hospital Karachi from November 2000 to December 2016. 18 patients who underwent PSAE for disabling hypersplenism caused by cirrhosis were included. Patients who were under 18 year of age, or in whom PSAE were performed for reasons other than cirrhosis and those with missing records/incomplete data were excluded (n = 7). Information was collected regarding demographic details, procedure indications, nature, technique, clinical efficacy, repeat embolization and complications along with laboratory and radiological investigations. Results: Eighteen patients of cirrhosis with a mean age of 43.47 ± 10.926 years, of which 14 were males, underwent PSAE (19 procedures). Indications were severe hypersplenism which precluded treatment with interferon and ribavirin (n = 8) and recurrent Gastro-oesophageal variceal (GOV) bleeds due to advanced Child-Pugh grade and thrombocytopenia (n = 10). Hematological parameters improved significantly following PSAE. Three out of eight patients successfully completed interferon + ribavirin treatment for hepatitis C (HCV) infection post PSAE, and GOV bleeds stopped in eight out of 10 patients. Complications included mild Left upper quadrant (LUQ) abdominal pain n = 9 (47.3%), post-embolization syndrome n = 4 (21%), and clinically insignificant pleural effusion n = 4 (21%). One patient developed spontaneous bacterial peritonitis (SBP) which was appropriately managed. One patient needed re-emobilization after 6 months. Conclusion: PSAE is a safe and effective procedure in the treatment of hypersplenism due to cirrhosis.展开更多
