RESUMEN
Nutcracker syndrome (NCS) is a rare condition caused by compression of the left renal vein (LRV) between the aorta and superior mesenteric artery. Surgical treatment is reserved for patients with severe symptoms and failure of conservative treatment. A 31-year-old woman diagnosed in adolescence with NCS has had recurrent pain since age 15. For 30 days, she has had severe left flank pain and microhematuria. The patient underwent extravascular stent placement around the LRV with the Da Vinci Xi. In 30 months of follow-up, the patient has no pain and the LRV remained without compressions or thrombosis.
RESUMEN
Background: Proximal splenorenal shunt (PSRS) is one of the most commonly performed portosystemic shunt (PSS) in extrahepatic portal venous obstruction (EHPVO) for portal decompression. Sometimes various anatomical and surgical factors related to the splenic vein and/or left renal vein may make the construction of a PSRS difficult or impossible. Unconventional shunts are required to tide over such conditions. Methods: From January 2008 to December 2018, 189 patients with EHPVO underwent PSS, of which, the 10 patients who underwent unconventional shunts form the study group of this paper. Results: The ten unconventional shunts included 8 proximal splenoadrenal shunts, one collateral-renal shunt, and one inferior mesenteric vein to inferior vena cava (IMV-Caval) shunt. The mean percentage drop in omental pressure was 34.2% post-shunt with a mean anastomotic diameter of 13.7 ± 3.1 mm. Three patients experienced some form of postoperative complication. With a mean follow-up period of 32.3 months (maximum of 111 months) all patients had patent shunts on follow-up Doppler. None of the patients had variceal bleed, or features of biliopathy and hepatic encephalopathy in follow-up. Conclusion: Unconventional shunts can be used safely and effectively with good postoperative outcomes in EHPVO.
RESUMEN
INTRODUCTION: Due to the complexity of the surgical procedure portal vein thrombosis (PVT) has long been considered an absolute contraindication to liver transplantation (LT). The presence of a large splenorenal shunt (SRS) could make portal anastomosis a valid option. PRESENTATION OF CASE: We report the case of a 37-year-old female patient with Grade III PVT and a large SRS, who underwent orthotopic LT. Liver was implanted using a 1992-Belghiti piggyback technique and portal anastomosis was performed using the large spleno-renal shunt. We observed good graft reperfusion and postoperative Doppler ultrasound showed normal portal vein flow. She was discharged on postoperative day 7, with an excellent graft function. At six months follow-up, patient is alive with normal hepatic vascularization. DISCUSSION: Due to paucity of reports, there is currently no consensus on the indication to LT and/or surgical technique. In the present case, once the transplant benefit was evaluated, the Grade III PVT was not considered a contraindication to LT. CONCLUSION: The presence of a Grade III PVT associated with a large SRS should not be considered a contraindication for LT, and the use of the shunt vein should be considered a feasible option to perform portal anastomosis.
