OBJECTIVE: To evaluate endoluminal occlusion of the inferior vena cava (IVC) during surgical treatment of renal cell carcinoma (RCC) with either retrohepatic (level II) or suprahepatic (level III) caval tumour thrombus. PATIENTS AND METHODS: From January 2000 to February 2005, 31 patients with renal vein/IVC involvement (T3b/c) of 278 who had a radical nephrectomy, were selected for review. Of these 31, 13 consecutive patients with RCC presenting a thrombus level II or III were prospectively treated with endoluminal occlusion of the free IVC cranial to the thrombus, to avoid dissection of the suprahepatic IVC or the subdiaphragmatic IVC. The occlusion balloon was positioned using transoesophageal echocardiography (TEE) control through a cavotomy at the ostium of the renal vein. Thrombectomy and radical nephrectomy were then performed. The operative duration, peri-operative bleeding, and complications during and after surgery were assessed. Overall patient survival time, disease-free survival and development of metastasis were calculated. RESULTS: Caval thrombectomy was successful in all patients. The IVC needed to be replaced with an expanded polytetrafluoroethylene graft in three patients and a patch closure after lateral cavectomy was used in four. There was no case of air embolism. One case of asymptomatic tumour migration was detected during the procedure by TEE. The mean (sd) and median (range) operative duration was 170 (29) and 170 (120-210) min, and the mean number of units of packed red cells transfused during hospitalization was 5 (5) and 3 (0-16). There was no peri-operative mortality. The complications were one splenectomy and one early thrombosis of the IVC. The mean (range) follow-up was 22.1 (2-50) months. Distant metastases occurred in seven patients; there was no local or IVC tumour recurrence. Four patients died from metastatic progression and six are alive with no progression. CONCLUSION: Endoluminal occlusion of the IVC with TEE monitoring for level II and III thrombus avoided a suprahepatic or subdiaphragmatic approach to the IVC. This technique caused no major complications and was very reliable, due to TEE monitoring. Segmental resection and reconstruction of the IVC could also be used for adherent thrombi. 相似文献

BACKGROUND: We investigated the advantages of intraoperative transesophageal echocardiography (TEE) during inferior vena caval tumor thrombectomy in renal cell carcinoma (RCC). METHODS: Five patients with RCC that extended into the inferior vena cava (IVC) underwent radical nephrectomy. To remove the tumor thrombus in the IVC, an inflated Fogarty balloon catheter was used to pull the thrombus below the level of the hepatic veins with real-time TEE monitoring. RESULTS: In all cases, TEE monitoring during surgery provided an accurate and excellent view of the IVC thrombus. TEE was particularly helpful for the thrombectomy to minimize hepatic mobilization by using occlusion balloon catheter in two patients whose thrombus extended to the intrahepatic IVC. CONCLUSIONS: Intraoperative real-time TEE monitoring is a safe, minimally invasive technique that can provide accurate information regarding the presence and extent of IVC involvement, guidance for placement of a vena caval clamp, confirmation of complete removal of the IVC thrombus and intervention using catheters to assist in thrombectomy. 相似文献

BACKGROUND: The surgical management of renal tumours with thrombi in the inferior vena cava (IVC) has become the gold standard treatment. OBJECTIVE: To evaluate endoluminal occlusion of the IVC during radical nephrectomy with either retrohepatic (level II) or suprahepatic (level III) caval tumour thrombus. DESIGN, SETTING, AND PARTICIPANTS: From January 2000 to October 2007, 28 consecutive patients with renal cell carcinoma presenting a thrombus level II or III were treated with endoluminal occlusion of the free IVC cranial. SURGICAL PROCEDURE: The occlusion balloon was positioned under transesophageal echography (TEE) control through a cavotomy performed at the level of the renal vein ostium. Thrombectomy and radical nephrectomy were then performed. MEASUREMENTS: Operative time, perioperative bleeding, and pre- and postoperative complications were assessed. Overall patient survival time, disease-free survival, and development of metastasis were assessed. RESULTS AND LIMITATIONS: Caval thrombectomy was performed successfully in all patients. IVC replacement with an expanded polytetrafluoroethylene graft or patch closure after lateral cavectomy was performed in 10 and 4 patients, respectively. Average operative time was 160min (range: 120-210). There was no perioperative mortality. The complications were one splenectomy and one early thrombosis of the IVC. Mean length of follow-up was 22.1 mo (range: 3-90). There was no local or IVC tumour recurrence. Cause-specific death and metastasis occurred in six (21.4%) and nine patients (32.1%), respectively. Thirteen patients (46.4%) are disease-free. CONCLUSIONS: Endoluminal occlusion of the IVC with TEE monitoring for level II and III thrombus avoided a suprahepatic or subdiaphragmatic approach of the IVC. Segmental resection and reconstruction of the IVC could also be performed in case of adherent thrombi. 相似文献

OBJECTIVE: A surgical strategy for treating malignant renal tumors with thrombus extending into the inferior vena cava (IVC) was assessed. METHODS: We retrospectively reviewed the records for all patients with renal cell carcinoma (RCC; n=30) or Wilms tumor (n=1) with tumor thrombus extending into the IVC who underwent surgical intervention at our institution between January 1980 and December 2001. Tumors were classified preoperatively according to the cephalad extension of thrombus, and intraoperative procedures were selected on the basis of degree of extension. Patients with RCC underwent radical nephrectomy and removal of thrombus with (n=11) or without (n=19) IVC resection. Partial normothermic cardiopulmonary bypass without cardiac arrest was used in 4 patients. The Pringle maneuver was performed in 8 patients. Infrarenal abdominal aortic cross-clamping was used in 8 patients to maintain systemic blood pressure. IVC cross-clamping and the Pringle maneuver were performed in 5 patients with suprahepatic thrombus extension. Temporary placement of a filter in the IVC or plication of the IVC above the hepatic vein was performed before hepatic mobilization, to decrease the risk for pulmonary embolism. RESULTS: One patient died intraoperatively of pulmonary embolism. Postoperative complications occurred in 11 patients; all resolved with conservative therapy. The postoperative duration of survival in patients with RCC was 37 +/- 44 months (range, 4-180 months); the 5-year survival rate was 42%. CONCLUSION: Aortic cross-clamping during IVC occlusion prevented hypotension and maintained hemodynamic stability that has required bypass in other series. This surgical treatment with the less extensive approach could result in long-term survival of patients with RCC in whom tumor thrombus extends into the IVC. We recommend that radical nephrectomy and tumor thrombectomy, with or without caval resection, be performed in these patients, with less invasive additional maneuvers. 相似文献

Renal cell carcinoma has a tendency to extend via the renal vein into the inferior vena cava (IVC), and we describe a novel approach to this situation. A 64-year-old male presented with metastatic right renal cell carcinoma and tumor thrombus extending into the retrohepatic IVC. Preoperative imaging revealed a large hemangioma adjacent to the IVC, potentially complicating hepatic mobilization. Instead, we used a compliant balloon to occlude the suprahepatic IVC, securing the wire in the right hepatic vein. With the infrarenal IVC and left renal vein occluded, the thrombus was extracted via a right renal venotomy/partial cavotomy with minimal bleeding. Balloon occlusion of the suprahepatic IVC offers a safe alternative to surgical control of this vessel in difficult situations. In addition, it allows for nephrectomy through a conventional, small retroperitoneal incision rather than the extended exposure needed for the IVC. Hepatic vein positioning of the wire prevents thrombus manipulation during balloon placement. 相似文献

Endometrial stromal sarcoma (ESS) rarely extends into the inferior vena cava (IVC). Two cases of ESS extending into the IVC
were encountered. In the first case a low-grade sarcoma and cavography revealed the tumor thrombus to extend to just below
the left renal vein from the right internal iliac vein, and the IVC was patent. A tumor thrombectomy was accomplished to prevent
pulmonary embolism (PE) and to achieve a good prognosis. The second case was also a low-grade sarcoma. Abdominal computed
tomography scanning revealed a large thrombus extending into the IVC just below the hepatic vein. A tumor thrombectomy with
an IVC resection was performed. The postoperative course was uneventful for both cases. Aggressive surgical treatment is thus
recommended to excise a tumor thrombus with or without an IVC resection in patients with ESS of low-grade malignancy extending
into the IVC to prevent sudden death due to PE. 相似文献

ObjectivesWe evaluated the clinical outcome and factors affecting survival in patients with renal cell carcinoma (RCC) and tumor thrombus involving inferior vena cava (IVC).MethodsBetween 1990 and 2007, 28 patients with RCC and tumor thrombus extending into IVC underwent radical nephrectomy and thrombectomy. Patient data were reviewed retrospectively to evaluate the demographics, clinical presentation, surgical approach, pathological features, clinical outcomes, and survival.ResultsTwenty-eight patients with a mean age of 52.7 years were operated. Thrombus level was infrahepatic in 15 patients (54%), intrahepatic in 3 patients (10%), suprahepatic in 3 patients (10%), supradiaphragmatic in 2 patients (8%), and intracardiac in 5 patients (18%). All patients with intracardiac thrombi underwent cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA). The mean tumor size was 98.21 mm. Four patients had distant metastases and 3 patients had lymph node involvement. Pathological examination revealed RCC of clear cell type in 26 patients, papillary in 1 and chromophobe in 1 patient. At a mean follow-up of 36.4 months, 16 patients were still alive while 8 patients died due to disease progression and 2 patients died of other causes. Two patients died of pulmonary emboli in the early postoperative period. Lymph node involvement, distant metastases, hypercalcemia, and sarcomatoid component were found to be factors affecting overall survival significantly. Level of tumor thrombus and Fuhrman grade did not affect survival.ConclusionsRadical nephrectomy and tumor thrombectomy is currently known to be the most effective method in patients with RCC and tumor thrombus extending into IVC. Factors affecting survival are the ones related to tumor biology. Tumor thrombus level does not affect the prognosis. 相似文献

BACKGROUND: The successful excision of a renal cell carcinoma (RCC) invading the inferior vena cava (IVC) remains a technical intraoperative challenge and requires a careful preoperative surgical management planning. Although a radical operation remains the mainstay of the therapy for RCC, the optimal management of the patients with RCC causing IVC tumor thrombus remains unresolved. In this study, we reviewed our experience in this group of patients and herein report the results. METHODS: Between July 1990 and August 1998, 11 patients with RCC with IVC tumor thrombus underwent surgical treatment. The mean patient age was 54.2 years and the male to female ratio was 1.75. The cephalad extension of the tumor was suprarenal in all cases, being infrahepatic in 6 patients, intrahepatic in 2, and suprahepatic with right atrial extension in 3 patients. All tumors were resected via inferior vena cava isolation and, when necessary, extended hepatic mobilization and Pringle maneuver, with primary or patch closure of vena cavotomy. Cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA) were used in 3 patients. RESULTS: The mortality rate was 9.1% (1 patient was lost on the 11th postoperative day). Complications occurred in 3 patients. The remaining 10 patients (90.9%) could be successfully discharged from hospital. Two of them were lost during follow-up because of tumor progression at the 43rd and 54th postoperative months. The 10-year Kaplan-Meier survival estimate was 71.4%, with a mean follow-up of 4.6 years. The presence of lymph node metastases and perinephric spread seemed to possess an adverse effect on the survival. Although the groups included small numbers of patients, there was no significant difference in survival in regard to the different levels of tumor thrombus extension into the vena cava. CONCLUSIONS: Surgical treatment is the preferred approach to patients with RCC and IVC tumor thrombi as it provides markedly better results when compared with the other therapeutical modalities. We believe that complete surgical excision of the tumor and the resulting thrombus with appropriate preoperative staging and a well-planned surgical approach, using CPB and DHCA when necessary, provide an acceptable long-term survival with a good quality of life expectation. 相似文献

Surgical management of renal cell carcinoma (RCC) with a tumour thrombus that infiltrates the caval wall or extends above the hepatic veins can be problematic. Total control of the suprahepatic inferior vena cava (IVC) is mandatory in order to prevent thrombus mobilization and minimize blood loss. Pump-driven veno-venous bypass (VVB), modified by adding portal decompression, is a safe and useful procedure and avoids the important risks connected with deep hypothermic circulatory arrest while allowing the normal perfusion of vital organs. 相似文献

The objective of this study is to describe a single-center experience of caval thrombectomy in patients with renal cell carcinoma (RCC) and tumor thrombus extension into the inferior vena cava (IVC). We retrospectively reviewed 23 patients undergoing radical nephrectomy with caval thrombectomy. Follow-up included an office visit and computed tomography scan. Statistical comparisons were made using 2-sample t tests. Patients' ages ranged from 32 to 83 years (mean, 62 years; 18 male, 5 female). Tumor size ranged from 3 to 21 cm (mean, 8.6 cm). Tumor thrombus staging was based on the Nevus classification: level I (2/23), II (6/23), III (13/26), IV (2/23). Tumor thrombi were removed by means of digital extraction (20), Fogarty embolectomy (2), or endarterectomy (1-caval wall invasion). Lateral venorrhaphy was used for IVC repair in all cases. Hepatic mobilization and suprahepatic clamping were necessary in 14 patients. Clamp times were significantly different between the suprahepatic (SH) and infrahepatic (IH) groups (15 vs 9.4 minutes, P < .012). Mean blood loss was also significantly different (3.2 L vs 2 L, P < .045). In the SH group, 2 patients developed postoperative atrial fibrillation and 2 patients died (respiratory failure; missed enterotomy). The IH group had no perioperative morbidity or mortality. Median followup was 15 months (range, 1-54 months). Follow-up imaging was available for 19/23 patients. Ninety-five percent of patients had a patent IVC (18). One SH patient developed an IVC stenosis/thrombosis 12 months postoperatively with successful thrombolysis and stenting. There was a 16% (3/19) recurrence rate in follow-up, with all patients demonstrating renal vascular invasion and high Fuhrman grade upon final pathologic evaluation. Caval thrombectomy can be performed safely during radical nephrectomy for RCC with tumor thrombus extension. The need for suprahepatic clamping is associated with longer clamp times, increased blood loss, and increased morbidity and mortality. Lateral venorrhaphy with primary repair avoids complicated caval reconstructions and results in high patency rates, despite a not insignificant recurrence rate. 相似文献

OBJECTIVE
To evaluate our experience with surgical resection of renal cell carcinoma (RCC) with inferior vena cava (IVC) involvement and examine the relationship between prognosis and tumour extent.PATIENTS AND METHODS
A retrospective review of nephrectomy performed between 1985 and 2005 identified 50 patients presenting with tumour thrombus extension into the IVC. Clinical characteristics and outcome were evaluated.RESULTS
Of the 50 patients evaluated, 7, 26, 10 and 7 presented with level I, II, III and IV thrombus, respectively. Major postoperative complications occurred in 16% of patients. Local or distant failure occurred in 25 (64%) patients. The mean time to recurrence was 10 months. Only supra‐diaphragmatic extension of the tumour thrombus was predictive of disease recurrence.CONCLUSION
Locally advanced RCC with IVC thrombus remains associated with significant local and distant failure rate. The level of thrombus extension is significantly associated with disease recurrence. Effective adjuvant therapy is needed to improve outcome in this patient population. 相似文献18.

Renal cell carcinoma (RCC) develops tumor thrombus in the renal vein and inferior vena cava (IVC) in 10% of cases. Surgical treatment is radical nephrectomy and thrombectomy of the IVC. Local recidive can develop in the lumbar fossa, lymph nodes, and the IVC. We report a 58-year-old patient admitted to the Clinic for Urology at the Military Medical Academy, Belgrade, Serbia, in February 2009 with RCC of the left kidney and tumor thrombus in the IVC. After ultrasonography exam and multislice computed tomography scan, we performed radical nephrectomy and thrombectomy of the IVC (level II). Four months after the operation, ultrasound exam and cavography showed intracaval and paracaval recidive tumor masses in the renal part of the IVC. On operation we removed intraluminal IVC thrombus, which arises from the lumbar vein on the IVC posterior wall, with paracaval thrombus in the lumbar vein. We conclude that RCC tumor thrombus can spread from the kidney to the IVC through the lumbar vein. 相似文献

Tumor resection and caval tumor thrombectomy, with or without cavotomy and inferior vena cava (IVC) replacement are sometimes performed in patients with renal cell carcinoma (RCC) extending into the IVC or liver tumors invading the IVC. Two such cases were treated. Case 1: a 68-year-old female was transferred with a diagnosis of right RCC with tumor thrombus extending into the IVC. A plication was performed to prevent extension into the right atrium before the nephrectomy and cavotomy with removal of the tumor thrombus was accomplished, because the IVC was almost completely obstructed and the hemodynamics were stable during cross-clamping of the IVC. Case 2: a 37-year-old female was transferred with a diagnosis of a giant metastatic liver tumor. A trisegmentectomy with resection of the invaded IVC and IVC replacement was performed while the abdominal aorta was cross-clamped to maintain the hemodynamics. Therefore, abdominal aortic cross-clamping was convenient to maintain the hemodynamics when the IVC replacement was performed during IVC cross-clamping. 相似文献
