Impact of Portal Flow on the Prognosis of Children With Congenital Portosystemic Shunt: A Multicentric Observation Study in Japan. J Pediatr Surg 2024:S0022-3468(24)00309-9. [PMID: 38839469 DOI: 10.1016/j.jpedsurg.2024.05.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 04/22/2024] [Accepted: 05/05/2024] [Indexed: 06/07/2024]
Abstract
BACKGROUND Although congenital portosystemic shunts (CPSSs) are increasingly being recognized, the optimal treatment strategies and natural prognosis remain unclear, as individual CPSSs show different phenotypes. METHODS The medical records of 122 patients who were diagnosed with CPSSs at 15 participating hospitals in Japan between 2000 and 2019 were collected for a retrospective analysis based on the state of portal vein (PV) visualization on imaging. RESULTS Among the 122 patients, 75 (61.5%) showed PV on imaging. The median age at the diagnosis was 5 months. The main complications related to CPSS were hyperammonemia (85.2%), liver masses (25.4%), hepatopulmonary shunts (13.9%), and pulmonary hypertension (11.5%). The prevalence of complications was significantly higher in patients without PV visualization than in those with PV visualization (P < 0.001). Overall, 91 patients (74.6%) received treatment, including shunt closure by surgery or interventional radiology (n = 82) and liver transplantation (LT) or liver resection (n = 9). Over the past 20 years, there has been a decrease in the number of patients undergoing LT. Although most patients showed improvement or reduced progression of symptoms, liver masses and pulmonary hypertension were less likely to improve after shunt closure. Complications related to shunt closure were more likely to occur in patients without PV visualization (P = 0.001). In 25 patients (20.5%) without treatment, those without PV visualization were significantly more likely to develop complications related to CPSS than those with PV visualization (P = 0.011). CONCLUSION Patients without PV visualization develop CPSS-related complications and, early treatment using prophylactic approaches should be considered, even if they are asymptomatic.

[PMID: 35194798 DOI: 10.1111/vsu.13785] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/27/2022] [Accepted: 01/31/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVE To describe the technique, complications, and outcome of laparoscopic portosystemic shunt attenuation (LPSSA) in dogs. STUDY DESIGN Retrospective study. ANIMALS Twenty client-owned dogs. METHODS Medical records were searched for dogs with a single congenital extrahepatic portosystemic shunt (CEPSS) that was treated with LPSSA. Signalment, clinical signs, CEPSS location, diagnostic imaging, laparoscopic approach, operative technique, complications, and clinical outcome were reviewed. RESULTS Fourteen dogs with CEPSS located in the epiploic foramen had a right (13/14) or left (1/14) paramedian approach. In 6 dogs a CEPSS was not located in the epiploic foramen, and a left paramedian approach was used. A 3 or 4-port technique was used in 7 and 13 dogs, respectively. A thin film band was used for CEPSS attenuation in all dogs. The median operating time for LPSSA was 62 min (range 27-98 min). Intraoperative complications requiring conversion to an open technique occurred in 5 dogs. Mild perioperative self-limiting portal hypertension occurred in 3 dogs, while severe portal hypertension with surgical revision occurred in 1 case. The complications were resolved, and all dogs had a good outcome. CONCLUSION Laparoscopic portosystemic shunt attenuation can be performed in dogs, in particular for a CEPSS located in the epiploic foramen using a right paramedian approach. For CEPSS not located in the epiploic foramen, a left paramedian approach is recommended. Conversion to open celiotomy was required in around a third of cases. CLINICAL SIGNIFICANCE Laparoscopic attenuation of CEPSSs can be performed in dogs and has a good clinical outcome, particularly for CEPSS located in the epiploic foramen.

Angiographic diagnosis for accurate assessment of congenital porto-systemic shunt and extrahepatic portal vein obstruction in children. Pediatr Int 2022; 64:e14856. [PMID: 34048141 DOI: 10.1111/ped.14856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 04/16/2021] [Accepted: 05/20/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Congenital porto-systemic shunt (CPSS) is a rare disease and can cause fatal complications. Accurate angiographic assessment is mandatory for proper treatment. Although technically difficult, we developed assessment techniques and assessed their accuracy. One technique came from evaluating patients with extrahepatic portal vein obstruction (EHPVO). METHODS We conducted a single center retrospective study to evaluate the efficacy of angiographic diagnostic procedure for the assessment of CPSS and EHPVO, and its impact on patients' subsequent interventions and clinical course. Eight patients with CPSS and two patients with EHPVO who underwent diagnostic angiography were included. Assessment of the intrahepatic portal vein was performed in all patients. The route of the shunt, and portal vein pressure under shunt occlusion, were also evaluated for patients with CPSS. Evaluation was first attempted with a balloon angiographic catheter (standard method). Three additional techniques were performed as needed: (i) direct wedge-catheter injection without balloon inflation, (ii) use of occlusion balloon in two patients, and (iii) hybrid angiography with sheath placement directly into the superior mesenteric vein. RESULTS The standard method was sufficient in four patients. On the other hand, all three techniques were required in two patients each. One lost contact during follow up, but all other patients underwent optimal intervention. There were no complications related to the angiographic procedure. CONCLUSIONS Use of direct wedge-catheter injection without balloon inflation, occlusion balloon, and hybrid catheterization improved the diagnostic yield in patients with CPSS or EHPVO.

Abstract
Liver transplantation has been historically recommended for patients with congenital absence of the portal vein associated with extrahepatic congenital portosystemic shunts. Here, based on a case report of a 2-year-old girl and a thorough review of all published cases from 1974 to 2020, we show that such a diagnosis most often conceals a hypoplastic portal vein, which can be successfully re-permeabilized through the closure of the shunt in order to re-establish a physiological vascular anatomy. This highlights the importance of achieving a detailed anatomical description of extrahepatic congenital portosystemic shunts with a balloon occlusion test in order to plan the best surgical approach and avoid unnecessary liver transplantation.

Efficacy and Safety of Surgical Ligation versus Endovascular Embolization for Type II Congenital Extrahepatic Portosystemic Shunt. BIOMED RESEARCH INTERNATIONAL 2021; 2021:9951393. [PMID: 34159206 PMCID: PMC8187072 DOI: 10.1155/2021/9951393] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 05/20/2021] [Indexed: 11/22/2022]
Abstract
Objective To evaluate the safety and efficacy of surgical ligation and endovascular embolization for the treatment of type II congenital extrahepatic portosystemic shunt (CEPS). Methods In this retrospective study, 23 patients diagnosed with type II CEPS between March 2011 and April 2019 were divided into either a surgical group (n = 13; 41.5 ± 19.9 years) or the interventional group (n = 10; 44.9 ± 19.7 years). The surgical group underwent laparoscopic surgical ligation of the shunt alone or ligation of the shunt and splenic artery and/or vein. The interventional group underwent endovascular embolization using microcoils, detachable coils, and vascular plug. Results All 23 patients received a one-step shunt closure, and their clinical symptoms were significantly improved within 3-month postprocedure and without recurrence during follow-up. The serum ammonia levels in both groups decreased after the procedure and dropped to normal level at 6- to 12-month postprocedure. Compared with baseline, the portal vein diameter in interventional group increased significantly at 3-, 6-, 12-, and 36-month postocclusion (P = 0.01 for all). The procedure time was shorter in the interventional group (127.0 ± 43.2 minutes) than the surgical group (219.8 ± 56.7 minutes; P < 0.001). The intraoperative blood loss in the interventional group (32.0 ± 62.5 mL) was less than that in the surgical group (238.5 ± 396.9 mL; P = 0.001). Conclusion Both surgical ligation and endovascular embolization are effective in the treatment of type II CEPS. Endovascular embolization has the advantages of shorter procedure time and less intraoperative blood loss. The ligation of the portosystemic shunt and splenic artery and vein is feasible with apparent safety, and it could avoid a second surgical treatment.

Radiological and surgical differences between congenital end-to-side (Abernethy malformation) and side-to-side portocaval shunts. J Pediatr Surg 2020; 55:1897-1902.

Abstract
OBJECTIVE Distinguishing retrohepatic end-to-side portocaval shunts (ES-PCS) and side-to-side portocaval shunts (SS-PCS) can be difficult, but it is essential for determining the treatment strategy. Our experience with retrohepatic PCS is analyzed. METHODS Since 2007, 9 children (5/9 ES-PCS and 4/9 SS-PCS) were surgically treated. Radiology studies included Doppler-ultrasound, CT/MRI and angiography/occlusion test (8/9). RESULTS CT in 5/5 ES-PCS revealed the portal vein (PV) entering the left side of the vena cava with a uniform shape. 4/4 SS-PCS showed aneurysmal PV containing the origin of the main intrahepatic portal branches (IHPB) entering the cava anterior aspect or slightly to the right with a variable length (from long to short/wide). ES-PCS anatomy showed caudate lobe absence with the fistula entering the left cava aspect free of parenchyma, but anterior through the caudate lobe in SS-PCS. With the angiography/occlusion test, the IHPB was undeveloped in ES-PCS (portal pressure > 38 mmHg) and hypoplasic in SS-PCS (portal pressure < 25 mmHg). ES-PCS treatment included: 1/5 hepatectomy and 4/5 definitive banding (one by laparoscopy); while in SS-PCS: 1/4 liver transplantation, 2/4 1-step closure (one by laparoscopy), and 1/4 definitive banding. CONCLUSION Fistula shape, cava relationship, IHPB and portal pressures differ between the two shunt types. A question arises regarding the need for secondary complete closure after banding.
