Emergency inferior mesenteric vein to left renal vein shunt in variceal bleeding: an alternative technique.

Shunt procedures being used in the emergency surgical management of variceal bleeding include total (portocaval shunt-PCS), partial (mesocaval H graft shunt-MCS) or selective shunts (distal splenorenal shunt-DSRS). We report the use of inferior mesenteric vein to left renal vein (IMV to LRV) shunt in an emergency situation in a 24 year old patient with noncirrhotic portal hypertension with variceal bleeding.

[Blood-pressure behavior in rats following the diversion of renal-vein blood into the portal vein].

Experimental studies on 22 hypertonic rats which had previously one kidney removed show that the deviation of the renal vein blood into the portal vein through a cavorportal or splenoportal anastomosis does not result in a lowering of the experimentally induced renovascular hypertension. These anastomoses did not alter the blood pressure in 3 normotonic rats. The prophylactic use of these anastomoses could not prevent the development of experimental renal hypertension in 2 of 3 test animals.

[A case of hepatocellular carcinoma with tumor thrombi in the first branch of the portal vein and hepatic vein trunks treated by transcatheter hepatic arterial chemoembolization and hepatic arterial infusion chemotherapy--two years and six months follow-up].

The patient was a 73-year-old man. In March 2002, abdominal computed tomography revealed hepatocellular carcinoma (HCC) with tumor thrombi in the first branch of the portal vein (Vp3) and two hepatic vein trunks (Vv2). He had no hepatitis virus. Serum AFP and PIVKA-II levels were as high as 6,919 ng/ml and 91,700 mAU/ ml, respectively. He was treated by transcatheter hepatic arterial chemoembolization (TACE) 3 times. On post 1st TACE week 8, he received hepatic arterial infusion chemotherapy (low-dose cisplatin and 5-FU) for Vp3 Vv2 HCC. The patient is still alive with no recurrence after two years and six months since the initial TACE treatment.

Preminary report: initial experience of endovascular laser therapy for varicose veins due to greater saphenous vein incompetence in Thailand.

BACKGROUND: Surgical venous stripping (SVS) is a standard treatment for varicose veins (VV) due to greater saphenous vein incompetence (GSVI) but there are some disadvantages to and risks. Endovascular laser (EVL) has been introduced to overcome these disadvantages. The present study was designed to determine the effectiveness of EVL treatment for these patients. MATERIAL AND METHOD: The patients with VV due to GSVI diagnosed by duplex scan were recruited in the present study. The EVL-procedure was percutaneously approached guiding by ultrasound under monitor anesthetic care (MAC). Postoperative clinical and imaging assessment was assessed. RESULTS: There were 17 limbs with symptomatic VVs in 11 patients. Two patients were admitted for a reason not related to surgery. The others were day cases. There was no postoperative complication except a large echymosis in one case. At 3-month follow-up, no recanalization or recurrence was detected. CONCLUSION: The authors' early results demonstrated that EVL could obliterate VVs due to GSVI and further showed some benefits over SVS. More studies with a longer period of follow-up are needed to further confirm the efficacy of EVL.

Portal vein thrombosis after laparoscopic colectomy: thrombolytic therapy via the superior mesenteric vein.

Portal vein thrombosis is a rare but well-reported complication after laparoscopic surgery. We present a case of portomesenteric venous thrombosis that occurred 8 days after a laparoscopic-assisted right hemicolectomy. Systemic anticoagulation failed to improve symptoms. The early postoperative state precluded the use of transarterial thrombolytic therapy. Transjugular intrahepatic catheter-directed infusion of urokinase into the superior mesenteric vein resulted in clearance of thrombus and resolution of symptoms. The published data on laparoscopy-induced splanchnic venous thrombosis and transjugular intrahepatic intramesenteric thrombolysis are discussed.

[Correction of insufficiency of communicating veins in varicose veins of the lower extremities].

To simplify the techniques of the operation and attain a good cosmetic effect the authors suggest a new scalpel for excising the communicating veins. The method of the operation with the use of the scalpel and its results in 256 patients are described. Comparative analysis by means of modern complex diagnostic methods gives hope. The disease recurred in 3.6% of cases. The good cosmetic effect with simultaneous shortening of the hospitalization period allows the new method of epifascial communi- cant vein surgery to be recommended for application in practice.

[The concentration of endothelin in maternal vein, umbilical vein and artery of normal pregnancy and pregnancy-induced hypertension].

The concentrations of endothelin (ET) in maternal vein (MV), umbilical vein (UV) and artery (UA) of normal pregnancy (N) and severe pregnancy-induced hypertension (sPIH) were measured to investigate the significance of ET in the maternal and feto-placental circulation of normal pregnancy and PIH. 1) The concentrations of ET (pg/ml blood: mean +/- S.E.M.) in MV of a normal non-pregnant group, 1st, 2nd and 3rd trimester of N were 1.00 +/- 0.19 (n = 2), 0.55 +/- 0.16 (n = 4), 0.45 +/- 0.14 (n = 4) and 0.89 +/- 0.09 (n = 10), respectively. The concentration of ET in MV of 3rd trimester of sPIH was 2.76 +/- 1.21 (n = 7), and significantly (p less than 0.05) higher than in MV of 3rd trimester of N. 2) The concentrations of ET in UV and UA of N and UV of sPIH were 1.53 +/- 0.05, 1.29 +/- 0.06, 2.12 +/- 0.46, respectively. The concentrations of ET in UV and UA of N were significantly (p less than 0.01) higher than in MV of N. 3) The concentrations of ET in MV of N and sPIH correlated significantly (p less than 0.05) with diastolic blood pressure of N (r = 0.53). It was concluded that the synthesis of ET during pregnancy was suppressed until the 2nd trimester, and that the increased ET in MV of sPIH might be one of the factors that caused the pathogenesis of PIH. And the high concentration of ET in UV and UA was supposed to operate play a role in feto-placental circulation.

[Aneurysm of the deep veins of the legs. Apropos of a case involving a vein in the calf].

A fusiform venous aneurysm of a deep calf vein was discovered following pulmonary embolism occurring during laparotomy in a 59 year old woman. This lesion has especially been described at popliteal vein level and 25 cases were found in the literature. Analysis shows that the principal clinical manifestation is pulmonary embolism due to clot migration from the thrombosed aneurysmal pocket. Local signs are much rarer. Diagnosis depends on venography. Subsequent management of a venous aneurysm, discovered incidentally, remains unclear since the incidence of complications is unknown. Anticoagulant therapy is required in the presence of thrombotic complications. The general tendency is to combine a caval filter with resection of the aneurysm. The necessity for venous reconstruction following the latter remains debatable.

Portal vein or hepatic vein? A curious aberrant vasculature in the liver with idiopathic portal hypertension.

The existence of aberrant vasculatures has been described as one of the characteristic findings in the liver with idiopathic portal hypertension (IPH). In this paper, the morphological features and the genesis of aberrant vasculatures were studied on the basis of autopsy and biopsy materials of IPH and animal experiments. Aberrant vasculatures in IPH livers are characterized as thin-walled vessels located mainly adjacent to the portal tracts and at times in the hepatic lobules. Although some of them are morphologically very similar to hepatic vein branches, they are portal in nature. These aberrant vessels develop in order to compensate for portal circulatory insufficiency due to obliteration of portal vein branches, and play an important role in maintaining an adequate blood supply to the parenchyma. It is predicted that decrease of these intrahepatic collateral vessels is responsible for or related to parenchymal atrophy and deterioration of liver function in the advanced stage of this disease. We regard these vasculatures as characteristic of the intrahepatic portal venous obstruction, particularly with portal hypertension accompanied by increased portal blood flow.

[Thrombosis of the right internal jugular vein caused by a catheter in the subclavian vein. A complication precluding the insertion of a ventriculo-atrial cerebrospinal fluid shunt].

The Authors describe a case of right internal jugular vein thrombosis caused by a catheter in the subclavian vein which occurred in a four-month-old baby with chronic subdural hematomas. They emphasize that this thrombotic complication precludes the insertion of a ventriculo-cardiac shunt and point out the opportunity to prefer left subclavian cannulation in those patients who probably will need a ventriculo-cardiac shunt.

[Conjugated cholic acid in the portal vein, aorta and hepatic vein in patients with alcohol toxic liver cirrhosis].

In 12 patients with Laennec's cirrhosis conjugated cholic acid was measured by radioimmunoassay simultaneously in the portal vein, the aorta, and the hepatic vein. Furthermore, the concentration was measured for 90 minutes after i. v. injection of cholecystokinin. In the fasting patient the porto-venous extraction ratio was 0.45 (SD 0.23) and the arterio-venous extraction ratio was 0.24 (SD 0,21). 15-30 minutes after cholecystokinin the bile acid concentration significantly increased. In this time the porto-venous extraction ratio rose to 0.71 while the aorto-venous extraction ratio was different. These results agree with the hemodynamics found in cirrhosis. After cholecystokinin the increase in the extraction ratio account for the blood loss by porto venous shunts which corresponds to an increase of the portal compartment.

[Dilatation of the femoral veins in patients with vertical blood reflux in varicose veins].

The proximal part of the venous system of lower extremities is not always damaged in patients with the varicose disease. The greater the area of the damaged femoral veins by the varicose process, the greater the frequency of insufficient valves appearing against the background of ectasy of the corresponding veins and is of a relative character. The blood reflux may occur in any venous vessel.

[Role of the external saphenous vein in repeat surgery of primary varicose veins of the lower limbs].

Between January 1968 and June 1978, we required to carry out 170 repeat operations for primary varicose veins of the lower limbs. In 34 operations (21.9% of cases) the re-operation involved a surgical procedure on the external saphenous: --in 6 cases, isolated ligature of the arch, --in 28 cases, stripping of the short saphenous. In our practice surgical reoperation is only indicated when there is a substantial point of leakage between deep and superficial systems. Residual varicosities after surgery require simple post-operative sclerosis. Surgery to the short saphenous is carried out in various circumstances; a) Where the initial operation involved an error in technique: Wrongly sited ligature of the arch (5 cases). This occurs less frequently than in the cases of the internal saphenous . b) Where the first operation was defective by reason of a tactical error: The short saphenous had not been recognized as responsible for varicose veins and had been ignored. Where several years after an operation on the long saphenous, insufficiency developed in the short saphenous and required treatment in its turn. Preoperative assessment involved phlebography and a Doppler examination in the majority of cases. The results are difficult to assess since in nearly two thirds of the cases, surgery to the external saphenous was combined with a further surgical procedure on the internal saphenous.

[Analysis of three-dimensional imaging of the right hepatic vein and right portal vein branch using 2D-TOF MR angiography: evaluation of utility of MR angiography in determining puncture course on TIPS].

2D-TOF MR angiographies were performed in seven patients of liver cirrhosis with hepatocellular carcinoma to investigate three-dimensional anatomical relationships of the right hepatic vein and first order of right portal vein branch. The puncture course was set up in three-dimensional rectangular coordinates, and the bend angle and turning angle of the modified Ross needle, and puncture distance were calculated of the data measured on the A-P and L-R projection images of MR angiograms. The utility and limitation of 2 D-TOF MR angiography to determine the puncture course on TIPS were discussed in this study.
