“…(13), and Kato et al. (37) have reported an alternative technique, which requires neither interruption of portosystemic venous communications nor splenectomy during LTx. To maintain the portal inflow to the graft, they used an end‐to‐end anastomosis between the left renal vein and donor portal vein.…”

“…All patients showed normal portal venous flow as measured by intra‐ and post‐operative Doppler ultrasonography. One patient died because of hepatic artery thrombosis and related complications (15, 37). The authors claim that RPA should be the strategy of choice, if the patient has a pre‐existent spontaneous or surgically constructed splenorenal shunt prior to LTx.…”

“…All these cases demonstrate that portal reperfusion of the liver graft using caval inflow enabled transplantation in patients with diffuse PVT in adult as well as in pediatric LTx. Sheil et al (16), Azoulay et al (13), and Kato et al (37) have reported an alternative technique, which requires neither interruption of portosystemic venous communications nor splenectomy during LTx. To maintain the portal inflow to the graft, they used an end-to-end anastomosis between the left renal vein and donor portal vein.…”

“…It was also pointed out that the coaxiality and congruency between portal and renal vein should allow a better match between left renal and portal vein flow. Finally, it was addressed that the RPA preserves the physiological retrohepatic IVC, which loses only the left renal venous inflow (13, 15, 37).…”

Portal vein thrombosis (PVT), a common complication of end stage liver disease, is no longer considered a definite contraindication for liver transplantation (LTx). The clinical decision to perform an LTx in the case of PVT depends on the degree of PVT and the experience of the surgeon. Eversion thromboendovenectomy was suggested by most authors as the surgical technique of choice for PVT grade 1, 2, and 3. If PVT obstructs more extended parts of the porto-mesenteric venous circulation, surgical options would include different types of venous jump graft reconstructions or arterialization of the portal vein. Combined liver and small bowel transplantation is another possible alternative. Cavoportal hemitransposition (CPHT) and renoportal anastomosis (RPA) were recently particularly advocated as creative surgical strategies in case of diffuse PVT. In this work, we focus on CPHT and RPA surgical techniques during LTx, which attempts to secure the portal flow to the liver graft in case of pre-existent diffuse PVT. We provide a review of all reported clinical experience at international clinical centers using these techniques. According to our meta-analysis a total of 15 studies were published on this topic between 1996 and 2005. In summary, a total of 56 orthotopic LTx have been performed in 53 patients (28 men, 25 women) combined with either CPHT or RPA, for the purpose of providing the donor graft with adequate inflow. Mean age was 44 yr including two patients who were infants, with the youngest recipient being two yr old. Main indications for LTx were liver cirrhosis caused by viral hepatitis, alcoholic cirrhosis and cryptogenic cirrhosis. CPHT was performed in 46 cases, and RPA in 10 cases. Thirty-five of 53 patients (66%) had surgery previous to LTx. Of these, 13 patients (37%) [corrected] presented with a history of other previous surgical procedures for decompression of portal hypertension or treatment of associated complications (portocaval shunts, splenectomy, etc). Ascites, renal dysfunction, lower extremity and torso edema and variceal bleeding were dominant post-operative complications after CPHT or RPA noted in 22 cases (41.5%), 18 cases (34%), 17 cases (32%) and 13 cases (24.5%) respectively. Patients' follow-up ranged from two to 48 months. Thirty nine of 53 patients [corrected] (74%) survived [corrected] and 14 patients died (26%) [corrected] during the course of observation. Based on the literature, we conclude that the ideal technique to overcome PVT during LTx is still controversial. Short-term follow-up results of both methods are promising, however, long-term results are unknown at present. Furthermore, clinical follow-up and basic experimental work is required to evaluate the influence of systemic venous inflow to the liver graft with respect to long-term liver function and liver regeneration.

“…Dismantling a previously constructed shunt increases the complexity of the procedure and carries an additional risk of bleeding [2,3]. Kato et al have reported that anastomosis of the donor PV to the left renal vein without dismantling the shunt is an effective method of PV reconstruction for patients with a patent distal spleno-renal shunt [4,5]. In this case, a large IMV to left renal vein anastomosis was deliberately chosen as a central portal decompressive shunt in a patient thought to be an appropriate candidate for subsequent liver transplantation with the intention of using this approach to graft inflow in the subsequent transplant procedure with total mesenteric flow diverted via this route.…”
