RESUMO

BACKGROUND: Renal cell carcinomas are the most common form of kidney cancer in adults. In addition to metastasizing in lungs, soft tissues, bones, and the liver, it also spreads locally. In 2-10% of patients, it causes a thrombus in the renal or inferior vena cava vein; in 1% of patients thrombus reaches the right atrium. Surgery is the only curative option, particularly for locally advanced disease. Despite the advancements in laparoscopic, robotic and endovascular techniques, for this group of patients, open surgery continues to be among the best options. CASE REPORT: Here we present a case of successful tumor thrombectomy from the infrahepatic inferior vena cava combined with renal vein amputation and nephrectomy. Our patient, a 58 year old Albanian woman presented to the doctors office with flank pain, weight loss, fever, high blood pressure, night sweats, and malaise. After a comprehensive assessment, which included urine analysis, complete blood count, electrolytes, renal and hepatic function tests, as well as ultrasonography and computed tomography, she was diagnosed with left kidney renal cell carcinoma involving the left renal vein and subhepatic inferior vena cava. After obtaining informed consent from the patient we scheduled her for surgery, which went well and without complications. She was discharged one week after to continue treatment with radiotherapy, chemotherapy, and immunotherapy. CONCLUSION: Open surgery is a safe and efficient way to treat renal cell carcinoma involving the renal vein and inferior vena cava. It is superior to other therapeutic modalities. When properly done it provides acceptable long time survival and good quality of life to patients.

RESUMO

Trousseau syndrome is characterized by cancer-associated systemic thrombosis. We describe the first case of a successfully treated gallbladder adenocarcinoma accompanied by Trousseau syndrome. A 66-year-old woman presented with right hemiplegia. Magnetic resonance imaging identified multiple cerebral infarctions. Her serum carbohydrate antigen 19-9 and D-dimer levels were markedly elevated, and a gallbladder tumor was detected via abdominal computed tomography. Venous ultrasonography of the lower limbs revealed a deep venous thrombus in the right peroneal vein. These findings suggested that the brain infarctions were likely caused by Trousseau syndrome associated with her gallbladder cancer. Radical resection of the gallbladder tumor was performed. The resected gallbladder was filled with mucus and was pathologically diagnosed as an adenocarcinoma. Her postoperative course was uneventful, and she received a one-year course of adjuvant therapy with oral S-1. No cancer recurrence or thrombosis was noted 26 months postoperatively. Despite concurrent Trousseau syndrome, a radical cure of the primary tumor and thrombosis could be achieved with the appropriate treatment.

RESUMO

BACKGROUND AND AIMS: Besides the increased risk of perioperative morbidity, graft failure, and mortality, the majority of PVT are diagnosed at liver transplantation (LT). Improving preoperative management and patient selection may lead to better short-term and long-term outcomes and reduce the risk of a futile LT. The authors aimed to identify predictors of adverse outcomes after LT in patients with nonmalignant portal vein thrombosis (PVT) and improve donor to recipient matching by analyzing the results of the Italian cohort of LT recipients. METHODS: Adult patients who underwent LT in Italy between January 2000 and February 2020 diagnosed with PVT pre-LT or at time of LT were considered eligible for inclusion. Based on a survey encompassing all 26 surgeons participating in the study, a binary composite outcome was defined. Patients were classified as having the composite event if at least one of these conditions occurred: operative time more than 600 min, estimated blood loss greater than 5000 ml, more than 20 ICU days, 90 days mortality, 90 days retransplant. RESULTS: Seven hundred fourteen patients were screened and 698 met the inclusion criteria. The analysis reports the results of 568 patients that fulfilled the criteria to enter the composite outcome analysis.Overall, 156 patients (27.5%) developed the composite outcome. PVT stage 3/4 at transplant and need for any surgical correction of PVT are independent predictors of the composite outcome occurrence. When stratified by PVT grade, overall survival at 1-year ranges from 89.0% with PVT grade 0/1 to 67.4% in patients with PVT grade 3/4 at LT ( P <0.001). Nevertheless, patients with severe PVT can improve their survival when identified risk factors are not present. CONCLUSIONS: Potential LT candidates affected by PVT have a benefit from LT that should be adequately balanced on liver function and type of inflow reconstruction needed to mitigate the incidence of adverse events. Nonetheless, the absence of specific risk factors may improve the outcomes even in patients with PVT grades 3-4.

RESUMO

BACKGROUND: Recently, the outcomes of surgical treatment for advanced hepatocellular carcinoma (HCC) have improved. However, despite the technical advancements in laparoscopic liver resection (LLR), it is still not recommended as the standard treatment for HCC with portal vein tumor thrombosis (PVTT) because of the poor oncological outcomes. This study aims to compare the clinical outcomes of open liver resection (OLR) and LLR in patients with HCC with PVTT. METHODS: A total of 86 patients with PVTT confirmed in the pathological report between January 2014 and December 2018, were enrolled. Short-term, postoperative, and long-term outcomes, including recurrence-free survival and overall survival rates, were evaluated. RESULTS: No difference between the two groups, except for age, was detected. The median age in the laparoscopic group was significantly higher than that in the open group. Regarding the pathological features, the maximal tumor size was significantly larger in the OLR; other pathological factors did not differ. There was no significant difference between overall survival (OS) and recurrence-free survival (RFS). Vp3 PVTT (hazards ratio [HR] 6.1, 95% confidence interval [CI] 1.9-18.5), Edmondson grade IV (HR 4.7, 95% CI 1.7-12.9, p = 0.003), and intrahepatic metastasis (HR 3.9, 95% CI 2.1-7.2, p < 0.001) remained the unique independent predictors of recurrence-free survival according to a multivariate Cox proportional hazard regression analysis. CONCLUSIONS: Laparoscopic liver resection for the management of HCC with PVTT provides the same short- and long-term results as those of the open approach.

RESUMO

BACKGROUND: Portal vein thrombosis is a potentially devastating complication following pediatric liver transplantation. In rare instances of complete portomesenteric thrombosis, cavoportal hemitransposition may provide graft inflow. Here we describe long-term results following a case of pediatric cavoportal hemitransposition during liver transplantation and review the current pediatric literature. METHODS: A 9-month-old female with a history of biliary atresia and failed Kasai portoenterostomy underwent living donor liver transplantation, which was complicated by portomesenteric venous thrombosis. The patient underwent retransplantation with cavoportal hemitransposition on postoperative day 12. OUTCOME: The patient recovered without further complication, and 10 years later, she continues to do well, with normal graft function and no clinical sequelae of portal hypertension. CT scan with 3-D vascular reconstruction demonstrated recanalization of the splanchnic system, with systemic drainage to the inferior vena cava via an inferior mesenteric vein shunt. The cavoportal anastomosis remains patent with hepatopetal flow. Of the 12 previously reported cases of pediatric cavoportal hemitransposition as portal inflow in liver transplantation, this is the longest-known follow-up with a viable allograft. Notably, sequelae of portal hypertension were also rare in the 12 previously reported cases, with no cases of long-term renal dysfunction, lower extremity edema, or ascites. CONCLUSIONS: Long-term survival beyond 10 years with normal graft function is feasible following pediatric cavoportal hemitransposition. Complications related to portal hypertension were generally short-lived, likely due to the development of robust collateral circulation. Additional reports of long-term outcomes are necessary to facilitate informed decision making when considering pediatric cavoportal hemitransposition for liver graft inflow.

RESUMO

PURPOSE: The objective of this study was to evaluate the safety, efficacy, and feasibility of percutaneous mechanical thrombectomy (PMT) through a below-the-knee (BTK) approach for acute lower extremity deep venous thrombosis (DVT). METHODS: A retrospective review of DVT patients treated with PMT by the BTK approach at our center from April 2022 to August 2023 was performed. Their preoperative demographics, intraoperative data, and postoperative outpatient outcomes were analyzed. RESULTS: A total of 12 patients (67% men; mean age, 63 years) met the inclusion criteria. The BTK approach was successfully achieved in all patients through the posterior tibial vein (n = 1), anterior tibial vein (n = 2), and peroneal vein (n = 9). PMTs were achieved in 11 (92%) patients. Successful lysis (grade II and grade III lysis) was achieved in all patients with PMT. Four (33%) patients had residual venous occlusion over the popliteal vein. No intraoperative complications or bleeding events occurred in any of the patients. CONCLUSION: PMT via BTK puncture seems to be a safe and effective approach for treating lower extremity DVT. It is reserved for highly select patients with a low risk of bleeding and is performed at centers that have experience with this procedure.

RESUMO

PURPOSE: Residual or undertreated inflow disease is a major cause of stent occlusion following endovascular thrombectomy for iliofemoral deep venous thrombosis (DVT). The profunda femoral vein (PFV) is an important inflow vessel alongside the femoral vein but is traditionally challenging to treat via an antegrade popliteal approach. This technical note describes a novel approach for PFV clearance in iliofemoral thrombectomy via the popliteal vein. MATERIALS AND METHODS: Eight patients underwent PFV clearance as part of iliofemoral DVT thrombectomy via an antegrade popliteal approach. In seven patients, a popliteal-profunda communicating vessel was identified permitting PFV access and thrombectomy. In one patient, a popliteal-profunda communicator was not identified and an 'up and over' approach via the femoral bifurcation from the same popliteal access was utilised. Thrombectomy was performed using the Inari ClotTriever device or Penumbra's Indigo system. RESULTS: Technical success in PFV thrombectomy was 100%. Six patients (75%) underwent stenting for an iliac stenotic lesion or May Thurner compression point. At the four-week ultrasound follow-up, the pelvic iliofemoral segment was patent in 7 patients (87.5%). The PFV was patent in 7 patients (87.5%) whereas the FV was only patent in 4 patients (50%). One patient underwent reintervention for iliofemoral stent occlusion. No PFV injury occurred and no post-procedure profunda reflux was identified. CONCLUSION: PFV clearance can be achieved via an antegrade popliteal approach in iliofemoral thrombectomy to optimise inflow, negating the need for alternative or additional venous access. PFV may maintain upstream iliofemoral vein patency even with an occluded femoral vein. LEVEL OF EVIDENCE: Level 4, Case Series.

RESUMO

Stenting has become the first line of treatment for symptomatic chronic iliofemoral venous obstruction in patients with quality-of-life impairing clinical manifestations who have failed conservative therapy. Patient selection for such intervention is however dependant on clear identification of relevant clinical manifestations and subsequent testing to confirm the diagnosis. In this regard the physician engaged in management of such patients need to be well aware of symptoms and signs of chronic iliofemoral venous obstruction (CIVO), instruments used to grade chronic venous insufficiency (CVI) and determine quality of life in addition to diagnostic tests available and their individual roles. This review serves to provide an overview of the diagnosis of CIVO and patient selection for stenting.

RESUMO

BACKGROUND: Venous thrombosis (VT) after esophagectomy for esophageal cancer is an important complication, potentially leading to pulmonary embolism. However, there are few available information about the risk for the postsurgical VT. METHODS: This study included 271 patients who underwent esophagectomy for esophageal cancer between 2006 and 2019. Contrast-enhanced computed tomography (CT) was performed for all patients on the seventh postoperative day to survey complications, including VT. RESULTS: VT was radiologically visualized in 48 patients (17.7%), 8 of whom (16.7%) had pulmonary embolism. The thrombus disappeared in 42 patients, the thrombus size was unchanged in 5 patients, and 1 patient died. Multivariate analysis was performed on factors clinically considered to have a significant influence on thrombus formation. The analysis showed that CVC insertion via the femoral vein (odds ratio, 7.67; 95% CI, 2.64-22.27; P < 0.001), retrosternal reconstruction route (odds ratio, 3.94; 95% CI, 1.90-8.17; P < 0.001) and intraoperative fluid balance < 5 ml/kg/hr (odds ratio, 0.38; 95% CI, 0.17-0.85; P = 0.019) were independently related to VT. CONCLUSIONS: Intraoperative fluid balance < 5 ml/kg/hr, along with CVC insertion via the femoral vein and retrosternal reconstruction may be potential risk factors for VT after esophagectomy.

RESUMO

Although the thrombectomy system is very important, there are many other devices and supportive tools that build the foundation for a successful interventional procedure. We suggest a toolbox of acute DVT intervention to aid in all likely strategies to effectively remove thrombus from the deep venous vasculature.

RESUMO

Purpose: To analyze the related factors of portal vein thrombosis (PVT) after hepatectomy. Methods: A retrospective analysis was made on 1029 patients who underwent partial hepatectomy in the first affiliated Hospital of Chongqing Medical University from March 2018 to March 2023, including PVT group (n = 24) and non-PVT group (n = 1005). The general and clinical data of the two groups were collected. Univariate and multivariate logistic regression analysis was used to analyze the clinical information of the two groups. Result: The proportion of preoperative hepatitis B, liver cirrhosis, ascites, intraoperative blood transfusion, postoperative hemostatic drugs, preoperative prothrombin time, intraoperative portal occlusion time, operation time, international standardized ratio of prothrombin time on the first day after operation, D-dimer on the first day after operation, fibrin degradation products on the first day after operation and postoperative hospital stay in the PVT group were all higher than those in the control group (P < .05). The preoperative platelet and albumin in the PVT group were lower than those in the control group. Intraoperative blood transfusion, liver cirrhosis, ascites, international standardized ratio of postoperative prothrombin time, postoperative fibrin degradation products, hilar occlusion time and albumin were independent risk factors for PVT. Conclusion: There are many influencing factors of PVT after hepatectomy. Clinical intervention should be taken to reduce PVT. Clinical Registration Number: K2023-348.

RESUMO

Iliac vein stenting for the treatment of iliac vein compression syndrome (IVCS) has been gradually developed. This article investigated the long-term patency and improvement of clinical symptoms after endovascular stenting for iliac vein obstruction patients. From 2020 to 2022, 83 patients at a single institution with IVCS underwent venous stent implantation and were divided into two groups: non-thrombotic IVCS (n = 55) and thrombotic IVCS (n = 28). The main stent-related outcomes include technical success, long-term patency, and thrombotic events. The technical success rate of all stent implantation was 100%. The mean length of hospital stay and cost were higher in the thrombotic IVCS group than in the non-thrombotic ICVS group, as well as the length of diseased vessel segment and the number of stents implanted were higher than in the control non-thrombotic group. The 1-, 2-, and 3-year patency rates were 85.4%, 80% and 66.7% in the thrombosis group, which were lower than 93.6%, 88.7%, and 87.5% in the control group (P = .0135, hazard ratio = 2.644). In addition, patients in both groups had a foreign body sensation after stent implantation, which resolved spontaneously within 1 year after surgery. Overall, there were statistically significant differences in long-term patency rate outcome between patients with thrombotic and non-thrombotic IVCS, the 1-, 2-, and 3-year patency rates in non-thrombotic IVCS patients were higher than those in thrombotic IVCS patients.

RESUMO

Myeloproliferative neoplasms (MPN) are the most common cause of noncirrhotic, nontumoral portal vein thrombosis (PVT). Over 90 % of MPN patients with PVT carry the JAK2V617F mutation. Compared to other etiologies of PVT, patients with JAK2V617F MPNs are at increased risk of developing significant portal hypertension. However, when these patients develop refractory portal hypertensive complications requiring portosystemic shunt placement, they have limited options. Transjugular intrahepatic portosystemic shunt (TIPS) insertion is often not feasible, as these patients tend to have extensive, occlusive portal thrombus with cavernous transformation. Surgical portosystemic shunt creation can be an alternative; however, this is associated with significant mortality. In this report, we describe the novel use of a percutaneous mesocaval shunt for successful portomesenteric decompression in a patient with portal hypertension from PVT associated with JAK2V617F positive essential thrombocythemia.

RESUMO

BACKGROUND: The prognostic value of splenic vessel involvement in distal pancreatic adenocarcinoma remains controversial. The aim of the study was to assess its prognostic relevance in a large multicenter cohort. METHODS: Patients who underwent pancreatosplenectomy for distal pancreatic adenocarcinoma were identified from 5 pancreatic surgical centers. A pathology review of the surgical specimens was performed to assess splenic vessel involvement, defined as invasion of the vessel's adventitia or deeper, and confirm the presence of splenic vein tumor thrombosis. Prognostic factors associated with overall and relapse-free survival were evaluated. RESULTS: 149 patients underwent upfront surgery. Splenic vascular involvement was observed in 69 of them (46.3%). A parietal infiltration of the splenic artery or splenic vein was observed in 26 (17.5%) and 49 patients (32.8%), respectively. A pathologic tumor thrombosis of the splenic vein was identified in 22 patients (14.8%) and associated with larger tumors (>20 mm) (P = .023), more perineural (P = .017), and lymphovascular (P = .002) invasion, and more positive lymph node (P = .001). After a median follow-up of 50.8 months (95% confidence interval: 44.3-57.3), the cumulative 5-year overall and relapse-free survival were 46.2% and 33%, respectively. In multivariate analysis, in addition to lymph node metastasis (hazard ratio = 1.8; 95% confidence interval [1.1-3.1]; P = .023) and perineural invasion (hazard ratio = 3.5; 95% confidence interval [1.3-9.7]; P = .016), presence of splenic vein tumor thrombosis was the only splenic vascular involvement that affected independently the overall survival (HR = 2.3; 95% confidence interval [ 1.3-4.3]; P = .006). CONCLUSION: In resectable distal pancreatic adenocarcinoma, a pathologic tumor thrombosis of the splenic vein is an independent prognostic factor of overall survival. To define the perioperative oncological strategy, a preoperative evaluation of splenic vessel involvement and thrombosis is needed.

RESUMO

Porto-mesenteric venous thrombosis (PMVT) is a rare complication that is encountered in less than 1% of patients following laparoscopic sleeve gastrectomy (LSG). This condition could be conservatively managed in stable patients with no evidence of peritonitis or bowel wall ischemia. Nonetheless, conservative management may be followed by ischemic small bowel stricture, which is poorly reported in the literature. Herein, we present our experience regarding three patients who presented with manifestations of jejunal stricture after initial successful conservative management of PMVT. Retrospective analysis of patients who developed jejunal stenosis as a sequela after LSG. The three included patients had undergone LSG with an uneventful post-operative course. All of them developed PMVT that was conservatively managed mainly by anticoagulation. After they were discharged, all of them returned with manifestations of upper bowel obstruction. Upper gastrointestinal series and abdominal computed tomography confirmed the diagnosis of jejunal stricture. The three patients were explored via laparoscopy, and resection anastomosis of the stenosed segment was performed. Bariatric surgeons should be aware of the association between PMVT, following LSG, and ischemic bowel strictures. That should help in the rapid diagnosis of the rare and difficult entity.

RESUMO

Renal cell carcinoma accounts for two to three percent of adult malignancies and can lead to inferior vena cava (IVC) thrombosis. This condition can decrease the rate of 5-year survival for patients to 60%. The treatment of choice in such cases is radical nephrectomy and inferior vena cava thrombectomy. This surgery is one of the most challenging due to many perioperative complications. There are many controversial methods reported in the literature. Achieving the free of tumor IVC wall and the possibility of thrombectomy in cases of level III and level IV IVC thrombosis are two essential matters previously advocated open approaches. Nevertheless, open approaches are being replaced by minimally invasive techniques despite the difficulty of the surgical management of IVC thrombectomy. This paper aims to review recent evidence about new surgical methods and a comparison of open, laparoscopic, and robotic approaches. In this review, we present the latest surgical strategies for IVC thrombectomy and compare open and minimally invasive approaches to achieve the optimal surgical technique. Due to the different anatomy of the left and right kidneys and variable extension of venous thrombosis, we investigate surgical methods for left and right kidney cancer and each level of IVC venous thrombosis separately.

RESUMO

Venous thrombosis is a frequent disorder. A distinction is made between an acute phase of the disease and a chronic manifestation, the postthrombotic syndrome. In particular, proximal venous thrombosis/pelvic vein thrombosis can cause a life-threatening pulmonary embolism during the acute phase of the disease. The postthrombotic syndrome is characterized by the remodeling of the affected venous section, which is often caused by inflammation. Locally, the typical clinical finding is caused by scarred stricture of the vein with restricted drainage and peripheral venous hypertension. Acute thrombosis should be primarily treated by therapeutic anticoagulation and compression therapy of the affected extremity. The duration of these measures depends on clinical presentation, cause (provoked, unprovoked) and risk factors for venous thrombosis/recurrent thrombosis. Venous revascularization procedures are important both in the acute phase of the disease and in the treatment of postthrombotic syndrome. The recanalization treatment is mostly carried out as an endovascular or hybrid intervention and venous bypass procedures are reserved for special situations.

RESUMO

BACKGROUND: Endovascular management of portal vein thrombosis (PVT) is challenging. Transsplenic access (TSA) is growing as an access option to the portal system but with higher rates of bleeding complications. The aim of this article is to evaluate the efficacy and safety of transsplenic portal vein recanalization (PVR) using a metallic stent after pediatric liver transplantation. MATERIALS AND METHODS: This is a retrospective review of 15 patients with chronic PVT who underwent PVR via TSA between February 2016 and December 2020. Two children who had undergone catheterization of a mesenteric vein tributary by minilaparotomy were excluded from the patency analysis but included in the splenic access analysis. The technical and clinical success of PVR and complications related to the procedure via TSA were evaluated. RESULTS: Thirteen children with PVT were treated primarily using the TSA. The mean age was 4.1 years (range, 1.5-13.7 years), and the most common clinical presentation was hypersplenism (60%). Technically successful PVR was performed in 11/13 (84.6%) children, and clinical success was achieved in 9/11 (81.8%) children. No major complications were observed, and one child presented moderate pain in the TSA (from a total of 17 TSA). The median follow-up was 48.2 months. The median primary patency was 9.9 months. Primary patency in the first 4 years was 75%, and primary assisted patency was 100% in the follow-up period. CONCLUSIONS: Transsplenic PVR is a safe and effective method for the treatment of PVT after pediatric liver transplantation.

RESUMO

OBJECTIVE: To report our step-by-step technique for 3D laparoscopic radical nephrectomy and thrombectomy for a right renal tumor with level IV venous thrombus. Worldwide experience in minimally-invasive approach for such complex cases is limited. MATERIALS AND METHODS: A 66-year-old male was incidentally diagnosed with a right renal tumor. He had a medical history of hypertension and benign prostatic hyperplasia. Blood test analysis showed a hemoglobin of 11.2 g/dL and creatinine of 0.92 mg/dL. Liver function and bilirubin were within normal limits. Contrast-enhanced abdominal CT scan showed an 90/77/85 mm right renal mass with a level IV inferior vena cava (IVC) tumor thrombus. Cardiac MRI showed that the tumor thrombus was extending into the right atrium, through the tricuspid valve and into the right ventricle. There was no evidence of distant metastases. After a multidisciplinary team reviewed the case, the patient was scheduled for 3D laparoscopic radical nephrectomy and thrombectomy by mini-thoracotomy approach RESULTS: Retroperitoneal laparoscopic approach was used to ensure rapid access on the renal artery, with minimal mobilization of the renal vein, and to better isolate the posterior wall of the IVC. Surgery continued with the transperitoneal approach and the isolation of the infrarenal and infrahepatic IVC and left renal vein. Meanwhile the right femoral artery and vein and right jugular vein were cannulated. Mini-thoracotomy was performed and cardiopulmonary by-pass was started. Blood flow through the IVC and left renal vein was stopped, and the right atrium was opened to control the thrombus. Cavotomy was performed at the level of right renal hilum and the tumor thrombus was identified and sectioned. There were no signs of thrombus adherence to the IVC wall. The thoracic segment of the thrombus was completely extracted by the cardiovascular surgeons. Pringle maneuver was not necessary, as there was no retrograde bleeding. No intraoperative adverse events occurred, according to the Intraoperative Complications Assessment and Reporting with Universal Standards Criteria. The operative time was 7 hours. Blood loss was minimal, with no need of intra- or postoperative transfusions. Hospital length of stay was 8 days. Pathology revealed renal cell carcinoma, International Society of Urological Pathology 3, with negative surgical margins. At 9-months follow-up, the patient is doing well, without signs of local or distant recurrence. CONCLUSION: 3D laparoscopy is a feasible alternative to open surgery for the most complex cases, enabling very precise dissection and suturing. We have shown a case of successful 3D laparoscopic radical nephrectomy with IVC thrombectomy combined with mini-thoracotomy achieving complete intracardiac thrombus removal.
