Predictors of portal vein thrombosis after simultaneous hepatectomy and splenectomy: A single-center retrospective study. Asian J Surg 2024:S1015-9584(24)01503-3. [PMID: 39054154 DOI: 10.1016/j.asjsur.2024.07.131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 03/07/2024] [Accepted: 07/12/2024] [Indexed: 07/27/2024] Open
Abstract
BACKGROUND Although postoperative portal vein thrombosis (PVT) is a frequent complication of splenectomy, few studies have examined PVT after simultaneous hepatectomy and splenectomy (HS). The aim of this study was to clarify the risk factors for and characteristics of PVT after HS. METHODS This retrospective observational study included 102 patients, including 76 with liver cirrhosis (LC) and 26 without, who underwent HS between April 2004 and April 2021. The incidence and location of postoperative PVT detected on contrast-enhanced CT 1 week after surgery were analyzed. In addition, pre- and intraoperative parameters were compared between patients with postoperative PVT and those without in order to determine risk factors for PVT after HS. RESULTS Among the 102 patients, 29 (28.4 %), including 32.9 % with LC and 15.4 % without LC, developed PVT after surgery. Among the 29 patients with PVT, 21 (72.4 %), 4 (13.8 %), and 4 (13.8 %) developed thrombus in the intrahepatic portal vein only, extrahepatic portal vein only, and both the extra- and intrahepatic portal veins, respectively. Multivariable analysis showed that preoperative splenic vein dilatation was an independent risk factor for PVT after HS (odds ratio: 1.53, 95 % confidence interval: 1.156-2.026, P = 0.003). CONCLUSION Our results suggest that splenic vein dilatation is an independent risk factor for PVT after simultaneous HS, and that PVT after HS occurs more frequently in the intrahepatic portal vein. After HS for cases with dilated splenic veins, we should pay particular attention to the PVT development in the intrahepatic portal vein regardless of the type of liver resection.

Abstract
BACKGROUND Portal vein thrombosis (PVT) is a commonthsn complication after splenectomy in patients with cirrhosis. However, the predictors of postoperative PVT are not known. AIM To investigate the predictors of PVT after splenectomy in patient with cirrhosis. METHODS A total of 45 patients with cirrhosis who underwent splenectomy were consecutively enrolled from January 2017 to December 2018. The incidence of PVT at 1 months, 3 months, and 12 months after splenectomy in patients with cirrhosis was observed. The hematological indicators, biochemical and coagulation parameters, and imaging features were recorded at baseline and at each observation point. The univariable, multivariable, receiver operating characteristic curve and time-dependent curve analyses were performed. RESULTS The cumulative incidence of PVT was 40.0%, 46.6%, and 48.9% at 1 months, 3 months, and 12 months after splenectomy. Multivariable analysis showed that portal vein diameter (PVD) ≥ 14.5 mm and monthsdel end-stage liver disease (MELD) score > 10 were independent predictors of PVT at 1 months, 3 months, and 12 months after splenectomy (P < 0.05). Time-dependent curve showed that the cumulative incidence of PVT was significantly different between patients with MELD score ≤ 10 and > 10 (P < 0.05). In addition, the cumulative incidence of PVT in the PVD ≥ 14.5 mm group was significantly higher than that in the PVD < 14.5 mm group (P < 0.05). CONCLUSION Wider PVD and MELD score > 10 were independent predictors of PVT at 1 months, 3 months, and 12 months after splenectomy in patient with cirrhosis.

Abstract
BACKGROUND The primary aim of the present study was to explore risk factors for portal vein system thrombosis following splenectomy. METHODS A systematic search of PubMed, Embase and Cochrane libraries was conducted to identify original studies that fulfilled the inclusion criteria. Raw data on potential risk factors for portal vein system thrombosis after splenectomy were extracted for meta-analysis. Subsequently, a sensitivity analysis was conducted to verify the stability of the results. RESULTS Eighteen studies with 626 thrombosis events from 1807 splenectomy met the inclusion criteria. Larger spleen volume (SMD 0.44, P = 0.000), broader splenic vein diameter (WMD 2.30, P = 0.000), broader portal vein diameter (WMD 2.08, P = 0.000), a lower velocity of portal blood flow (WMD -0.91, P = 0.001), decreased platelet count (WMD -5.14, P = 0.007), decreased white blood cell (WMD -0.40, P = 0.027), decreased haemoglobin (WMD -9.14, P = 0.002), ascites (OR 1.81, P = 0.003) and bleeding history before surgery (OR 1.88, P = 0.002) were identified to be factors that exacerbated the risk of portal vein system thrombosis after splenectomy. Sex, age, preoperative prothrombin time, postoperative platelet count, postoperative D-dimer, operation time and intraoperative blood loss, did not increase the risk of thrombosis. CONCLUSION Larger spleen volume, broader splenic vein diameter, broader portal vein diameter, a lower velocity of portal blood flow, ascites, bleeding history before surgery, decreased platelet count, white blood cell and haemoglobin may increase the risk of portal vein system thrombosis.

Abstract
Objective Splenectomy is one crucial solution for hypersplenism with portal hypertension. However, portal vein system thrombosis (PVST) caused by hemodynamic changes affects the prognosis of patients. We analyze the changes in portal vein hemodynamics following splenectomy for Wilson’s disease combined with portal hypertension and the influencing factors that lead to PVST. Methods A retrospective cohort study was conducted, in which 237 Wilson’s disease patients with hypersplenism underwent splenectomy. The hemodynamic indices of the portal vein were monitored before surgery and on the 1st, 7th, and 14th days around surgery. The patients were divided into PVST and non-PVST groups. The clinical factors were identified by univariate and multivariate logistic regression. The Logit P was calculated according to the logistic regression prediction model, and the ROC curve for each independent factor was plotted. Results The portal vein velocity, flow, and inner diameter showed a downward trend around surgery, with statistically significant differences between each time point (P < 0.01). The PVST incidence rate was 55.7%. Univariate analysis revealed that the platelet (PLT) levels on the postoperative 3rd and 7th days (P = 0.001; P < 0.001), D-dimer (D-D) on the postoperative 7th and 14th days (P = 0.002; P < 0.001), preoperative portal vein velocity, flow, diameter (P < 0.001), and splenic vein diameter (P < 0.001) were all statistically and significantly different between the two groups. Multivariate logistic regression revealed a significant increase in PLT on the postoperative 7th day (OR = 1.043, 95% CI, 1.027–1.060, P < 0.001) and D-D on the postoperative 14th day (OR = 1.846, 95% CI, 1.400–2.435, P < 0.001). Preoperative portal and splenic vein diameters (OR = 1.565, 95% CI, 1.213–2.019, P = 0.001; OR = 1.671, 95% CI, 1.305–2.140, P < 0.001) were the risk factors for PVST. However, preoperative portal vein velocity and flow (OR = 0.578, 95% CI, 0.409–0.818, P = 0.002; OR = 0.987, 95% CI, 0.975–0.990, P = 0.046) were protective factors for PVST. Logit P was calculated using a logistic regression prediction model with a cut-off value of −0.32 and an area under receiver operating characteristic curve of 0.952 with 88.61% accuracy. Conclusions Splenectomy relieves portal hypertension by reducing the hemodynamics index. PVST is linked to multiple factors, including preoperative portal vein diameter, velocity, flow, and splenic vein diameter, especially PLT on the postoperative 7th day and D-D on the postoperative 14th day. The predictive model is accurate in predicting PVST.

Abstract
BACKGROUND Portal vein thrombosis (PVT) is a common complication following splenectomy. It affects between 5 and 55% of patients undergoing surgery with no clearly defined pre-operative risk factors. The aim of this study was to determine the pre-operative risk factors of PVT. PATIENTS AND METHOD Single centre, retrospective study of data compiled for every consecutive patient who underwent splenectomy at Toulouse University Hospital between January 2009 and January 2019. Patients with pre- and post-surgical CT scans have been included. RESULTS 149 out of 261 patients were enrolled in the study (59% were males, mean age 52 years). The indications for splenectomy were splenic trauma (30.9%), malignant haemopathy (26.8%) and immune thrombocytopenia (8.0%). Twenty-nine cases of PVT (19.5%) were diagnosed based on a post-operative CT scan performed on post-operative day (POD) 5. Univariate analysis identifies three main risk factors associated with post-operative PVT: estimated splenic weight exceeding 500 g with an OR of 8.72 95% CI (3.3-22.9), splenic vein diameter over 10 mm with an OR of 4.92 95% CI (2.1-11.8) and lymphoma with an OR of 7.39 (2.7-20.1). The role of splenic vein diameter with an OR of 3.03 95% CI (1.1-8.6), and splenic weight with an OR of 5.22 (1.8-15.2), as independent risk factors is confirmed by multivariate analysis. A screening test based on a POD 5 CT scan with one or two of these items present could indicate sensitivity of 86.2% and specificity of 86.7%. CONCLUSION This study suggests that pre-operative CT scan findings could predict post-operative PVT. A CT scan should be performed on POD 5 if a risk factor has been identified prior to surgery.

Abstract
BACKGROUND Minimally invasive splenectomy is now well established for a wide range of pathologies. Portal vein thrombosis (PVT) is increasingly being recognised as a complication of splenectomy. The aim was to determine the incidence and risk factors for PVT after laparoscopic splenectomy. METHODS All cases of elective laparoscopic splenectomy performed from 1993 to 2020 were reviewed. Parameters recorded included demographics, diagnostic criterion and post-operative outcomes. Data were analysed using Minitab V18 with a p < 0.05 considered significant. RESULTS 210 patients (103 female, 107 male) underwent laparoscopic splenectomy (14 to 85 years). A major proportion of cases were performed for ITP (n = 77, p = 0.012) followed by lymphoma (n = 28), indeterminate lesions (n = 21) and myelofibrosis (n = 19). Ten patients developed symptomatic portal vein thrombosis (4.8%). Patients presented most commonly with pain and fever and diagnosis was confirmed by computed tomography (CT) or ultrasonography (USS). There were 10 conversions (4.8%) to open and two postoperative deaths, one from PVT and one from pneumonia. The remaining nine patients were successfully treated with anticoagulation. Of 19 patients with myelofibrosis, six patients developed PVT (p = 0.0002). Patients who developed PVT had significantly greater specimen weights (1773 g vs 348 g, p < 0.001). Forty-three patients had a specimen weight of 1 kg or greater, and of these 9 developed portal vein thrombosis (21%), versus one with PVT of 155 with a specimen weight of less than 1 kg (p < 0.0001). Myelofibrosis (p = 0.0039), specimen weight (p < 0.001) and mean platelet count (p = 0.0049) were predictive of PVT. CONCLUSION A high index of suspicion for this complication should be maintained and prompt treatment with anticoagulation. High-risk patients should be considered for prophylactic anticoagulation and routine imaging of the portal vein.

Abstract
Background The aim of this study was to establish and validate an easy-to-use nomogram to predict portal vein thrombosis (PVT) in patients with cirrhosis after splenectomy and to test its predictive ability. Material/Methods This retrospective study included 315 patients with cirrhosis who underwent splenectomy at 2 high-volume medical centers. The least absolute shrinkage and selection operator (LASSO) regression method was used to select the predictors in the training cohort, and multivariable logistic regression analysis was performed to establish the predictive nomogram model. We determined the prediction value of the nomogram by the area under the receiver operating characteristic curve (AUROC), the calibration curve, and decision curve analysis. Finally, the applicability of the nomogram was internally and independently validated. Results The predictors of PVT included portal vein diameter, splenic vein diameter, body mass index, and platelet count. Based on the clinical and radiomic models, the nomogram had good predictive efficiency for predicting PVT in patients with cirrhosis after splenectomy, with an AUROC of 0.887 (0.856 in internal validation and 0.796 in independent validation). The decision curve analysis revealed that the nomogram had good clinical application value. Conclusions We successfully developed an easy-to-use nomogram to predict the probability of PVT in patients with cirrhosis after splenectomy. The nomogram can help clinicians make timely, individualized clinical decisions for PVT in patients with cirrhosis after splenectomy.
