Duplexsonographische Untersuchungen zur Pathogenese der lienalen Hämodynamik bei Leberzirrhose

2008

AIM OF STUDY The haemodynamic role of the spleen in portal hypertension remains unclear. Duplex sonography was undertaken prospectively to discover the relationship of splenomegaly and splenic vein flow to type and severity of liver cirrhosis and portal vein flow, as well as to the degree of oesophageal varices. PATIENTS AND METHODS 89 patients (54 men, 35 women; mean age 52 [26-81] years), diagnosed in the second half of 1993 as having liver cirrhosis were consecutively included in the study. In 40 patients the cirrhosis was in stage A (according to Child-Pugh classification), in 31 in stage B and in 18 in stage C. RESULTS Portal vein flow fell significantly with increasing degree of cirrh…

Vascular complications following bladder drained, simultaneous pancreas-kidney transplantation: the University of Miami experience

2000

Vascular complications remain a significant nonimmunologic source of pancreas allograft loss. From February 1993 through January 1998, we performed 98 simultaneous pancreas-kidney transplantations (SPK) using pancreatic exocrine bladder drainage in patients with type 1 insulin-dependent diabetes mellitus and end-stage renal disease. They originally received quadruple immunosuppression, and since May 1997 triple immunosuppression protocol (tacrolimus, mycophenolate mofetil, and steroids). The patients' mean age was 37 years (range 24-53 years), including 50 women and 48 men with a mean follow-up of 42 months. The overall rate of vascular complications was 6% (5 patients). The vascular compli…

Incidence and predictors of portal and splenic vein thrombosis after pure laparoscopic splenectomy.

2017

Background. Optimal modalities for diagnosis, treatment, and surveillance of portal or splenic vein thrombosis have not yet been defined. The present retrospective study aimed to investigate the role of computed tomography performed systematically before and after laparoscopic splenectomy to assess the incidence of portal or splenic vein thrombosis, predictors, and outcomes. Methods. Computed tomography scans were obtained from 170 patients undergoing elective laparoscopic splenectomy between 2005 and 2015. Pre- and postoperative splenic vein diameter was measured at the splenoportal junction and at a distance of 2, 4, 6 cm from it. Univariate and multivariate analyses were used to identify…

Endovascular Embolization of a Large High-Flow Splenic Arteriovenous Fistula and Aneurysm Using the Amplatzer Vascular Plug II.

2015

We describe the use of an Amplatzer Vascular Plug (AVP) II for embolizing a large high-flow splenic arteriovenous fistula and an aneurysm in a young patient. This patient presented to our center with persistent mild abdominal discomfort, 5 years after open splenectomy. Contrast-enhanced computed tomography angiography showed the presence of a fistula between the splenic arterial and splenic venous remnants and a resultant fusiform aneurysmal dilatation of the residual splenic vein. We decide to embolize the splenic artery with a 12-mm diameter AVP II with an oversizing by 70% of the vessel diameter. Celiac angiography performed 5 min postembolization revealed complete obliteration of the sp…

Impact of structured report on the quality of preoperative CT staging of pancreatic ductal adenocarcinoma: assessment of intra- and inter-reader vari…

2019

Purpose: To evaluate whether a structured radiology report improves the completeness of preoperative CT staging of pancreatic ductal adenocarcinoma (PDA) compared to conventional free-text reports. Methods: We retrospectively included 27 patients (mean age, 64 ± 11.1 years) referred for pancreatic preoperative CT scan for staging of PDA between 2015 and 2018 and in whom a diagnosis of pancreatic adenocarcinoma was ultimately confirmed. Four readers independently reported CT scans with both conventional free-text and structured reports. Differences in reported morphologic and vascular features with the two reports were assessed through McNemar Test. Intra-reader and inter-reader were calcula…

Cancer-cell traffic in the liver. I. Growth kinetics of cancer cells after portal-vein delivery

1992

Following the intrasplenic injection of B16F10 melanoma cells into mice, at first single cells, and later multicellular tumor foci were observed at different times in the liver. Cell numbers and tumor volumes were determined over the next 12 days, by confocal microscopy of thick liver sections. Fifteen minutes after injection, approximately 20% of the melanoma cells were identified in the liver microvasculature; after 48 hr, only 0.68% of these retained morphologic integrity; by 5 days only 0.13% of the originally detected cells incorporated BUdR; and, by 12 days, these subsequently grew into tumor nodules. Tumor volume changes with time were not exponential and, following a non-replicative…

Budd-Chiari syndrome with portal, splenic, and superior mesenteric vein thrombosis treated with TIPS: who dares wins.

2003

A 20 year old man presented with severe ascites and malnutrition due to Budd-Chiari syndrome (BCS) with portal vein (PV), and splenic and mesenteric vein (SMV) thrombosis in the proximal 3 cm. He had received regular and more frequent paracenteses of up to 17 litres each for eight months. He had a poor BCS prognostic index of 8.41 (table 1). After referral, despite full anticoagulation and diuretic drugs, he deteriorated over three weeks. No thrombophilic disorder was found. View this table: Table 1 Comparison of laboratory and clinical data before and two months after transjugular intrahepatic portosystemic stent shunt (TIPS) He underwent transjugular intrahepatic portosystemic stent shunt…
