Transhepatic portal access was created under fluoroscopic guidance with an 8-F vascular ...
The authors experience with over 2,000 splenoportograms during a 14-year period provides the basis for this monograph describing the techniques, complications, and both intrahepatic and extrahepatic abnormalities demonstrable by splenoportography. The reader will find lucid directions for intrasplenic injection, an excellent verbal description of sites of obstruction of the splenoportal system, and a variety of reproductions of splenoportograms illustrating numerous abnormalities. Proper emphasis is given to the importance of preoperative splenoportography in patients with splenomegaly; the author repeatedly stresses the value of the examination in neoplastic and inflammatory disease of the pancreas; and descriptions of altered venous patterns in various ...
Aim: The objective was to evaluate whether contrast-enhanced magnetic resonance imaging (MRI) techniques used in a pre-operative assessment protocol for colorectal liver metastases are as accurate as spiral computer tomography during arterial portography (CTAP). Pre-operative accuracy and clinical consequences of MRI are described and compared with CTAP. Moreover, post-operative survival rate and tumour recurrence were studied. Methods: The study group comprised 84 patients which were possible candidates for a partial hepatectomy for colorectal liver metastases. Patients were pre-operatively evaluated by CT of the abdomen, CT of the thorax and spiral CTAP and ferumoxide-enhanced MRI was performed in routine way for all patients. Following this selection, 35 patients underwent a partial hepatectomy with curative intent. All patients were retrospectively evaluated. Results: Ferumoxide-enhanced MRI proved to be at least as accurate as spiral CTAP in 81% of patients. In nine patients (11%) spiral ...
Idiopathic hepatic fibrosis was diagnosed by liver biopsy in 15 young dogs, of which nine were German shepherds. Clinical signs included ascites, anorexia, weight loss and hepatic encephalopathy. Erythrocyte microcytosis was a consistent clinical feature, and clinical chemistry generally revealed hypoproteinaemia and high serum activities of alkaline phosphatase and, to a smaller extent, alanine aminotransferase. Fasting blood ammonia and serum bile acid concentrations were increased in most dogs examined, and all the dogs tested had prolonged retention of sulfobromophthalein at 30 minutes. Multiple acquired portosystemic shunts were revealed by laparotomy and/or portography. Non-inflammatory fibrosis was present to different degrees in all the dogs livers, and on the basis of its predominant location these were classified as having central perivenous fibrosis, diffuse pericellular fibrosis or periportal fibrosis. The response to symptomatic treatment and anti-fibrotic therapy with ...
In the enrolled patients, the χ2-test illustrated that the selleck products SV was the predominant originating vein of the LGV (P < 0.001). In the 98 patients included, the mean LGV, PV and SV diameters were 6.0 ± 3.2 mm (range, 2.0-17.6), 12.9 ± 2.6 mm (range, 6.2-24.2) and 9.3 ± 2.2 mm (range, 4.7-14.9), respectively, for the first measurements. For the repeated measurements, the mean LGV, PV and SV diameters were 5.9 ± 3.1 mm (range, 2.1-17.4), 12.8 ± 2.9 mm (range, 6.4-24.9) and 9.3 ± 2.1 mm. (range, 4.5-15.2), respectively. The intraobserver concordance of LGV, PV and SV diameter measurements on MR portography was good because the rc values were 0.90, 0.92 and 0.98, respectively; and the first measurements were used as the final diameter values.

Michelle Grattan has characterised the incoming Abbott Liberal-National government as being determined to weaken protections that Labor had introduced, although she noted these attempts were defeated by the Senate crossbench.[8] In light of an account fraud scandal at US-bank Wells Fargo, on 5 May 2014 ABC TV Four Corners, in conjunction with Fairfax journalists, broadcast an exposé of a sales-driven culture within the Commonwealth Banks (CBA) financial planning division, that was described as profit at all cost.[1] Chaired by Labor Senator Mark Bishop, a subsequent Senate committee inquiry recommended a royal commission into the fraud scandal that left thousands of CBA customers millions of dollars out of pocket. The committee reported on the performance of the Australian Securities and Investments Commission (ASIC).[2] Several days later, CBA chief executive Ian Narev apologised unreservedly to customers who lost money in the banks financial planning scandal. Treasurer at the time, Joe ...
The aim of this study was to evaluate whether variant meso-Rex bypass with transposition of abdominal autogenous vein can be used as an alternative treatment modality for selected patients with symptomatic extrahepatic portal vein obstruction. This was a retrospective review of six consecutive patients who received this alternative procedure for the treatment of symptomatic portal hypertension secondary to idiopathic extrahepatic portal vein obstruction. Their clinical characteristics, operative procedures and outcomes were analyzed retrospectively. The procedure was attempted in six patients, and all had a patent shunt established by intraoperative portography at the end of the procedure; the coronary vein was used in four patients and the inferior mesenteric vein was used in two. During the median period of 23.5 months (range 10-30 months), follow-up was uneventful except one patient; reduced portal hypertension and no new episodes of gastrointestinal bleeding were observed in all patients, with the

cavernous transformation. A network of collateral vessels may form around a thrombosed main portal vein at the porta, especially if the thrombosis is due to extrahepatic causes (for example pancreatitis) rather than diseased liver. The appearance of cavernous transformation of the PV is quite striking (Fig. A 1) and colour Doppler is particularly useful in its diagnosis. Make sure, before diagnosing PV thrombosis, that the vein axis is less than 60° to the transducer and that the Doppler sensitivity is set to pick up lowvelocity flow. Ultrasound is known to have a falsepositive rate for PV thrombosis but this is often due to inadequate technique or insensitive equipment. False-negative results, indicating that flow is present in a vein which is actually thrombosed, are due to the detection of flow within a collateral vessel at the porta, which can be mistaken for the main ...

Introduction: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been successfully applied to increase the future liver remnant before a right trisectionectomy. Tumor infiltration to the right portal vein is a challenge situation. Material and methods: A patient with advanced gallbladder carcinoma underwent exploration. Intraoperative finding showed tumor infiltration of the right portal vein and the duodenum. In-situ split of the left lateral liver lobe combined with postoperative right portal vein embolization completed the concept of ALPPS.. Results: Successful right trisectionectomy in combination with whipple operation without tumor residual could be achieved 8 days later, while the liver remnant increased from 491 ml to 911 ml. Neither post-hepatectomy liver failure nor postoperative anastomotic leak has been observed. 3 month follow up has not shown any sign of tumor recurrence. Conclusion: In-situ split combined with postoperative right portal vein ...

The study was to investigate the role of color Doppler ultrasonography in the evaluation of the effect of Rex-bypass shunt on the cavernous transformation of the portal vein (CTPV) in children. Fifty children with symptomatic extrahepatic portal hypertension who received Rex-bypass shunt were retrospectively reviewed, and they were diagnosed with CTPV by ultrasonography. The clinical characteristics were analyzed before and after operation. Forty-five patients received color Doppler ultrasonography at 6 months after surgery, and good patency in the bypass vessels was displayed. The platelet count significantly increased (P | 0.001) and the esophagogastric varices were improved significantly (p | 0.001). The patency of bypass vessels on color Doppler ultrasonography was consistent with the changes in the platelet count and the degree of esophagogastric varices on gastroscopy before and after operation. The diameter of bypass vessels at 6 months was slightly larger than that at 7 days after operation, and

PurposeThis study was designed to analyze retrospectively the performance of cone-beam computed tomography (CBCT) hepatic arteriography in depicting tumors and their feeders and to investigate the related determining factors in chemoembolization for hepatocellular carcinoma (HCC).MethodsEighty-six patients with 142 tumors satisfying the imaging diagnosis criteria of HCC were included in this study. The performance of CBCT hepatic arteriography for chemoembolization per tumor and per patient was evaluated using maximum intensity projection images alone (MIP analysis) or MIP combined with multiplanar reformation images (MIP + MPR analysis) regarding the following three aspects: tumor depiction, confidence of tumor feeder detection, and trackability of tumor feeders. Tumor size, tumor enhancement, tumor location, number of feeders, diaphragmatic motion, portal vein enhancement, and hepatic artery to parenchyma enhancement ratio were regarded as potential determining factors.ResultsTumors were ...
The most common presentation of EHPVO is vomiting out blood or what is called as hematemesis.. Since the portal vein is blocked, a lot of blood is being carried by it from the intestine to the liver, there is formation of newer veins around the blocked portal veins -portal cavernoma- and also bypassing of the blood to the veins in the esophagus and stomach called varices. This helps to decompress the high pressure in the portal veins. These varices are fragile and when pressure builds up rupture easily which results in bloody vomits. These dilated veins are called varices.. The blood most commonly originates from the oesophageal varices but can also be because of varices in the stomach called gastric varices. Varices can also occur around the rectum and anus leading to rectal bleeding of fresh blood though uncommon.. Apart from fresh bleeding, slow bleeding from the digestive tract can lead to black sticky tarry stools called malena. This slow indolent bleeding can cause significant blood loss ...

Rhizopus oligosporus is a fungus of the family Mucoraceae and is a widely used starter culture for the production of tempeh at home and industrially. As the mold grows it produces fluffy, white mycelia, binding the beans together to create an edible cake of partly catabolized soybeans. The domestication of the microbe is thought to have occurred in Indonesia several centuries ago. R. oligosporus is the preferred starter culture for tempeh production for several reasons. It grows effectively at high temperatures (30-40 °C) which are typical of the Indonesian islands, it exhibits strong lipolytic and proteolytic activity that create desirable properties in tempeh and it produces metabolites that allows it to inhibit and thus outcompete other molds and gram-positive bacteria, including the potentially harmful Aspergillus flavus and Staphylococcus aureus. R. oligosporus is at present considered to be a domesticated form of Rhizopus microsporus and its proper taxonomic position is thus Rhizopus ...

In Case 1, a patient with portal hypertension due to liver cirrhosis had esophageal cancer type-III. ...
Background and Aim: This study aimed to evaluate the therapeutic efficacy and safety of repeated transarterial chemoembolization (TACE) with additional radiation therapy (RT) in hepatocellular carcinoma (HCC) with portal vein (PV) invasion.. Methods: We performed survival analysis of consecutive HCC patients with PV invasion according to the treatment modalities after stratification by the degree of PV invasion and liver function retrospectively.. Results: During 2005, 281 patients were newly diagnosed to have HCC with PV invasion at our institution. Repeated TACE or transarterial chemoinfusion (TACI) was performed in 202 (71.9%) patients and additional RT was performed for PV invasion in 43 of them. A total of 281 patients had a median survival of 5.2 months and a 2-year survival rate (YSR) of 19.2%. Repeated TACE showed significant survival benefits compared with conservative management in patients with PV branch invasion; median survival and 2-YSR was 10.2 vs 2.3 months and 33.7% vs 0% in ...
We read with interest the article by Bruix et al1 in which Sorafenib was regarded as the standard treatment for hepatocellular carcinoma (HCC) patients with portal vein tumour thrombosis (PVTT). However, Sorafenib can only confer 2-3 months of overall survival (OS) benefit2 ,3 and is inapplicable to many patients due to extensive side effects and high price. Zhong et al4 proposed that liver resection might provide survival benefit to patients with HCC-PVTT with adequate liver function. However, this proposal was based on literature survey, lacked definite patient inclusion criteria and failed to provide information on patients baseline characteristics. Therefore, explorations of alternative therapeutics for patients with HCC-PVTT are still needed.. Although not recommended by mainstream guidelines5 ,6 for patients with HCC-PVTT, transarterial chemoembolisation (TACE) has long been practiced in the clinic in selected patients with HCC-PVTT.7 ,8 Gamma knife surgery (GKS) has shown favourable ...

Bayramlar, H.; Totan, Y.; Cekiç, O.; Yazicioglu, K.M.; Aydin, E., 2000: Evaluation of hemodynamic changes in the ophthalmic artery with color Doppler ultrasonography after strabismus surgery
The liver is divided into eight segments based on the branching of the portal triads and hepatic veins. The structures of the portal triad (hepatic artery, portal vein, and biliary duct) are separate extrahepatically but enter the hepatic hilus ensheathed within a thickened layer of the Glisson capsule. The three main hepatic veins divide the liver into four sectors, each of which is supplied by a portal pedicle. The caudate lobe is an exception because its venous drainage is directly into the vena cava and therefore independent of the major hepatic veins. The four sectors delimited by the hepatic veins are called the portal sectors, and these portions of the parenchyma are supplied by independent portal pedicles arising from the right or left main pedicles. The divisions separating the sectors are called portal scissurae, within each of which runs a hepatic vein. Further branching of the pedicles subdivides the sectors into segments. The liver is thus subdivided into eight segments, with the ...

Hi Jan.. OK, I will try to help you.. but if you would please give more details.. including where you are at and what Hospital, etc.. this all helps.. First, I am very concerned that your details may not be accurate.. It would be rare for such a small tumor to go anywhere.. but then I am also concerned that your first scan may not be good enough. And if your surgeon has not ordered more scans with contrast then perhaps you have the wrong surgeon as well. I do not mean to alarm you, but IF you do have Renal Vein invasion then this is a bit more difficult. Was that first scan with contrast..? (sometimes they can not use contrast if your Kidney function is not good enough, but you need to know that as well).. I digress a bit.. keep in mind that Kidney Cancer is about 8% of all Cancers.. IF you have Renal Vein Invasion, then the rarity alone mandates careful selection of a surgeon. If you do have Renal Vein invasion the number one question to ask your surgeon... How many surgeries have you done ...
