Percutaneous transhepatic obliteration of gastroesophageal varices: some technical aspects.

Two cases of bleeding from gastroesophageal varices treated by variceal obliteration illustrate multiple routes of variceal supply, and alert embolizing angiographers to the presence of spontaneous portosystemic shunts which should be kept open. In one case, variceal obliteration required embolization of the left gastric vein and a transhepatic collateral originating from the left hepatic portal branch and contributing substantially to variceal filling. A second patient with a relatively large spontaneous splenorenal shunt had recurrent variceal bleeding two months after a successful embolization of the coronary vein and a short gastric vein. A repeat study revealed the recurrent varices were supplied by enlarged right gastric and gastroepiploic veins. Superior mesenteric venography was necessary for their visualization.     

Balloon-occluded antegrade transvenous obliteration of rectal varices: A case report

Patients with liver cirrhosis frequently experience rectal variceal bleeding subsequent to portal hypertension. Unlike gastroesophageal variceal bleeding, a well-established guideline does not exist in terms of management of bleeding rectal varices. A 75-year-old male with non-alcoholic-steatohepatitis induced cirrhosis presented with a 3-day history of severe rectorrhagia. Considering patient''s clinical history, TIPS was not performed and thus, a novel endovascular technique termed balloon-occluded antegrade transvenous obliteration was considered. Under conscious sedation, an occlusion was made through balloon catheter by sclerotic agents including air/sodium tetradecyl sulfate/Lipiodol. After the procedure, and in the 6 months follow up period the patient''s hemodynamic status was stable and he recovered without any serious complications. Balloon-occluded antegrade transvenous obliteration is a feasible and safe modality for treating rectal varices bleeding and could be used as an alternative approach in patients with contraindications to traditional treatments.     

Bleeding from esophageal varices exacerbated by splenic arterial-venous fistula: Complete transcatheter obliterative therapy

A cirrhotic patient who had previously undergone both mesocaval shunting and transthoracic esophageal and gastric devascularization with splenectomy (Sugiura procedure) presented with recurring intractable variceal hemorrhage. Diagnostic visceral angiography demonstrated a large splenic arterial-venous fistula and gastroesophageal varices. Transarterial occlusion of the fistula and transhepatic obliteration of the varices successfully done at one sitting prevented further bleeding. Follow-up angiography nine months later revealed persistent occlusion of the previous fistula and no evidence of esophageal varices. This work was supported in part by the George Alfred Cook Memorial Fund through the Medical Research Foundation of Oregon.     

Risk and causes of gastroesophageal bleeding in patients with liver cirrhosis

BACKGROUND/AIM: Variceal bleeding is the most life-threating complication in liver cirrhosis. The aim of this study was to analyze the sources of gastroesophageal bleeding in patients with liver cirrhosis and to ascertain the risk factors of bleeding from esophageal varices. METHODS: This prospective study included 52 patients with liver cirrhosis and portal hypertension. Severity of liver dysfunction according to Child's classification, coagulation parameters, and endoscopic findings were analyzed. In patients with varices we analyzed the size, color, location of varices, and the presence of red signs. The varices were classified as small, medium and large. RESULTS: Esophageal varices were found in 76.9% of the patients. Isolated varices were present in 36.6%, and associated with other findings in 40.3%. Small varices were present in 10%, medium in 25% and large in 65% patients. Of them 55% had variceal bleeding. Variceal bleeding was present in 50% of the patients with medium and in 65.38% of the patients with large varices. There was no bleeding in the patients with small varices. Endoscopy revealed red signs before bleeding in 85% of the patients with large varices. There was a higher incidence of variceal bleeding in the Child's group B. There were no significant differences (p > 0.05) in the coagulation parameters in patients with and without variceal bleeding. Rebleeding was present in 86.36% of the patients. Most of them (52.63%) were rebleeding between 7 weeks and 12 months after the first episode of variceal bleeding. In the patients with the most severe hepatocellular dysfunction (Child's group C) the period between the first bleeding and rebleeding was the shortest (mean, 20.8 days). CONCLUSION: Our study revealed that esophageal varices are the most frequent sources of bleeding in the patients with liver cirrhosis. There is the association between the first bleeding and large varices and the red signs. Coagulation disorders and hepatic dysfunction were not related to the initial episode of variceal bleeding. The risk of early rebleeding was higher in the patients with severe hepatic dysfunction (Child's class C).     

Emergency transhepatic obliteration of bleeding varices

Transhepatic obliteration of gastroesophageal varices was performed in 18 actively bleeding patients. The success of the procedure was related to the complete obliteration of the varices, as demonstrated by their disappearance at angiography. In 13 of the 14 patients in whom obliteration was complete, bleeding did not recur. Three of the 13 died of hepatic insufficiency within 18 days of embolization, and three refused surgery and were lost to follow-up. The remaining seven patients had portacaval or mesocaval shunts, and are doing well at a follow-up of 12 months. Transhepatic obliteration has, therefore, proved to be an effective emergency procedure in patients who will be acceptable surgical candidates at a later date.     

Endovascular obliteration of bleeding duodenal varices in patients with liver cirrhosis

The purpose of this paper is to describe our experience with endovascular obliteration of duodenal varices in patients with liver cirrhosis and portal hypertension. Balloon-occluded transvenous retrograde and percutaneous transhepatic anterograde embolizations were performed for duodenal varices in five patients with liver cirrhosis, portal hypertension, and decreased liver function. All patients had undergone previous endoscopic treatments that failed to stop bleeding and were poor surgical candidates. Temporary balloon occlusion catheters were used to achieve accumulation of an ethanolamine oleate–iopamidol mixture inside the varices. Elimination of the varices was successful in all patients. Retrograde transvenous obliteration via efferent veins to the inferior vena cava was enough to achieve adequate sclerosant accumulation in three patients. A combined anterograde–retrograde embolization was used in one patient with balloon occlusion of afferent and efferent veins. Transhepatic embolization through the afferent vein was performed in one patient under balloon occlusion of both efferent and afferent veins. There was complete variceal thrombosis and no bleeding was observed at follow-up. No major complications were recorded. Endovascular obliteration of duodenal varices is a feasible and safe alternative procedure for managing patients with portal hypertension and hemorrhage from this source.     

急诊TIPSS在控制食管胃底静脉曲张破裂大出血中的应用及意义

目的：观察食管胃底静脉曲张破裂大出血患者行急诊经颈静脉肝内门腔静脉内支架分流术（ＴＩＰＳＳ）的治疗效果，并讨论急诊ＴＩＰＳＳ在方法学方面的特点。材料与方法：２２例患者因食管胃底静脉曲张破裂大出血接受急诊ＴＩＰＳＳ治疗。术中同时行胃冠状静脉和（或）胃短静脉栓塞。３例存在自发脾－肾或胃－肾分流道者，在球囊导管闭塞分流道肾端的前提下，行经分流道逆行胃底静脉曲张栓塞。结果：２２例中，１９例止血成功；１６例建立分流道；术后２４小时再发出血４例，其中２例死亡。结论：急诊ＴＩＰＳＳ是治疗食管胃底静脉曲张破裂大出血的有效方法。在方法学方面，急诊ＴＩＰＳＳ强调尽量通过可能途径栓塞曲张静脉，以获得及时、可靠的止血效果。     

Transportal intravariceal sclerotherapy with N-butyl-2-cyanoacrylate for gastric varices

Four patients with gastric varices without catheterizable draining veins through a systemic vein were treated with transportal intravariceal sclerotherapy with n-butyl-2-cyanoacrylate (NBCA). In all patients, the gastric varices were successfully obliterated with 2-5 mL of NBCA-lipiodol mixture injected via a microcatheter introduced into the varices with transhepatic or transileocolic portal venous access. No complications related to the procedure were encountered. Follow-up gastroendoscopy showed disappearance (n = 3) or marked decrease (n = 1) of the varices. Neither recurrent gastric varices nor variceal bleeding were observed during the follow-up period (6-46 months). Transportal intravariceal sclerotherapy is useful for obliteration of gastric varices in selected cases.     

Application of Balloon-Occluded Retrograde Transvenous Obliteration to Gastric Varices Complicating Refractory Ascites

We report two cases of gastric varices complicated by massive ascites that disappeared after balloon-occluded retrograde transvenous obliteration (B-RTO). The first patient had progressive gastric varices that continued to enlarge even after three episodes of esophagogastric variceal bleeding, and the second patient was admitted to our hospital because of the bleeding from gastric varices. After B-RTO procedures in both patients, significant improvement of the ascites, hepatic function reserve, and hypoalbuminemia was observed. Although further experience is needed, our experience points to the likelihood of the amelioration of ascites after B-RTO.     

Percutaneous transhepatic obliteration of gastroesophageal varices using absolute alcohol

Eleven patients underwent percutaneous transhepatic portography and esophageal variceal sclerosis. Absolute alcohol was used. Only two patients rebled in the follow-up period; both individuals died. Two additional patients died without further bleeding. The remaining seven patients survived from 13 to 19 months without rebleeding. Absolute alcohol is useful as a sclerosing agent for varices and may produce a more permanent and distal occlusion of gastroesophageal varices.     

Transhepatic obliteration of gastroesophageal varices with absolute ethanol

Absolute ethanol was evaluated as a vaso-obliterative agent in 15 patients with bleeding of gastroesophageal varices. Initial control of hemorrhaging was obtained in 13 (87%). Two patients died from unrelated causes within 48 hours of the procedure. Variceal bleeding recurred in seven of the 11 remaining patients (64%) from one week to 13 months after embolization. Four patients did not rebleed; two of them died (4 weeks and 6 months after the procedure), and two are alive (14 and 16 months after the procedure). Significant disadvantages of ethanol for obliteration of gastroesophageal varices (marked prolongation of procedure time and lack of radio-opacity) probably contributed to the high incidence of portal vein thrombosis (3 patients [20%]).     

经皮胃冠状静脉栓塞术联合部分脾栓塞术在门静脉高压症治疗中的应用

An emergency hybrid procedure that combines endoscopic treatment with partial splenic embolization for bleeding esophagogastric varices

Management of splenomegaly is important in the treatment of portal hypertension. We report 2 cases who were treated by an emergency hybrid procedure combining endoscopic treatment and partial splenic embolization (PSE) based on a new concept "splanchnic caput Medusae". Case 1 with refractory esophageal variceal bleeding due to alcoholic liver cirrhosis was treated by endoscopic injection sclerotherapy (EIS) with ligation and PSE at the same time. Case 2 with gastric variceal bleeding due to polycystic liver disease was treated by EIS using n-butyl-2-cyanoacrylate and PSE at the same time. Six days after the hybrid procedure, transjugular retrograde obliteration was added. In both cases, post-treatment 3D-CT reconstruction images revealed that the spleen-portal system reversed to almost normal form. We conclude that an emergency hybrid procedure combining endoscopic treatment and PSE is effective for patients with bleeding esophagogastric varices.KEYWORDS: Emergency hybrid procedure, Splanchnic caput Medusae, Esophagogastric varices, Endoscopic injection sclerotherapy, Partial splenic embolization, Polycystic liver disease     

Should balloon-occluded retrograde transvenous obliteration be the first-line interventional radiologic treatment for bleeding duodenal varices? A case report and review of the literature

We report a 78-year-old woman who presented with repeated tarry stools, and having lower duodenal variceal bleeding caused by portal hypertension. Endoscopic therapy had been attempted, but was impossible because the endoscope could not be inserted into the lower duodenum. Thus, the lower duodenal variceal bleeding was treated with balloon-occluded retrograde transvenous obliteration in combination with embolization using microcoils. Complete hemostasis was achieved without complications, and neither the recurrence of varices nor rebleeding has occurred for the last 3 years. A review of the English-language literature reveals only 11 such cases. The world literature is reviewed.     

双介入栓塞治疗门静脉高压食管、胃底曲张静脉出血及脾功能亢进

作者应用经皮肝穿曲张静脉栓塞术（ＰＴＯ）及部分脾栓塞术（ＰＳＥ）进行双介入栓塞（ＤＩＥ）治疗门静脉高压引起的食管、胃底曲张静脉出血及脾功能亢进１７例。结果显示，短期内（６～１８个月）止血效果良好（８２．３％），双介入栓塞前后门静脉内压力变化无显著差异（Ｐ＞０．０５），脾功能亢进完全缓解（１００％），外周血红、白细胞及血小板较双栓塞前明显回升（Ｐ＜０．０１）。肝功能有一定的恢复。双栓塞后可出现一定的合并症，但较轻微。我们认为此种双栓塞疗法治疗门静脉高压食管、胃底曲张静脉出血及脾功能亢进的病人是安全有效的。     

Iatrogenic intrahepatic arterial-portal fistula

We describe a case of an iatrogenic intrahepatic arterial-portal fistula that developed after percutaneous transhepatic variceal embolization. The fistula led to early recurrent bleeding after embolization and was successfully treated by selective catheter occlusion with the use of a coil spring. The occurrence and management of arterial-portal fistulae in interventional liver procedures and ethanol embolization of gastroesophageal varices are discussed.     

Pitfalls in transhepatic portography.

Difficulties commonly encountered in transhepatic catheterization of the portal vein and interpretation of portograms are discussed. A long-sleeved trocar is recommended. Curved guide wires and deflector assemblies may assist in superselective catheterization of the tributaries of the portal vein. The judicious use of embolic material (small volumes, slowly injected) should guarantee the success and safety of this technique. Transhepatic obliteration of the gastroesophageal veins is a relatively simple and usually successful form of palliative treatment for actively bleeding and stable gastroesophageal varices. Thoroughness of the embolization procedure and of interruption of blood flow in the gastroesophageal veins is necessary to prevent early recurrence of bleeding.
