Successful management of inferior vena cava thrombus complicating advanced germ cell testicular tumor with temporary inferior vena cava filter

We report a case of right testicular tumor with inferior vena cava (IVC) thrombus. Due to the risk of pulmonary embolization, a temporary IVC filter had been inserted during chemotherapy. There were no complications with the temporary IVC filter during the implantation period. The patient was safely treated with systemic chemotherapy using a temporary IVC filter followed by retroperitoneal lymph node and vena cava dissection.     

Testicular cancer with tumor thrombus extending to the inferior vena cava successfully removed using veno-venous bypass: A case report

A 33-year-old man with a left testicular tumor was referred to Shinshu University Hospital for advanced therapy. Radiographic imaging revealed multiple metastases in the retroperitoneal lymph nodes (RPLN) and bilateral lungs, as well as tumor thrombus that extended from the left renal vein to the inferior vena cava (IVC) adjacent to the right atrium. After orchidectomy, a diagnosis of embryonal carcinoma was made with a clinical stage of T1N2M1bS3, which has a poor prognosis, based on the International Germ Cell Cancer Collaborative Group consensus. After eight courses of chemotherapy, the patient's tumor markers normalized and the lung metastases disappeared, but the RPLN and tumor thrombus remained. Retroperitoneal lymph node dissection and thrombectomy were performed using a veno-venous bypass (VVB). The pathological examination of the thrombus revealed a mature teratoma. The patient has been disease-free since surgery.     

Renal arteriovenous malformation with thrombus in the inferior vena cava

BACKGROUND: Thrombus formation in the inferior vena cava (IVC) is usually seen in cases with malignancy. In contrast, vascular anomalies hardly ever accompany this disorder. Herein, a case of thrombus formation in the IVC associated with renal arteriovenous malformation (AVM) is reported. METHODS/RESULTS: A 50-year-old woman who received transarterial embolization (TAE) for AVM in the right kidney noticed right flank pain with macrohematuria 12 months later. Because radiographic evaluation could not rule out malignancy in the kidney, nephrectomy was performed. During nephrectomy, a palpable thrombus was found in the IVC, so thrombectomy was performed simultaneously. Histopathologic examination revealed an old infarction due to the TAE, circumferential arteriovenous thrombi and a large organized thrombus up to the IVC, but neither renal cell carcinoma nor transitional carcinoma in the kidney. CONCLUSIONS: Careful observation may be required, even after treatment for renal AVM, such as TAE, to avoid the formation of an IVC thrombus.     

En bloc mobilization of the inferior vena cava and large hypervascular right renal tumors with or without inferior vena cava thrombus: Posterior ligation of the renal artery

We describe our approach of posterior ligation of the renal artery during resection of large hypervascular right renal tumors. This technique uses en bloc mobilization of the inferior vena cava and renal tumor to ligate the renal artery at its origin from the aorta. In our experience, the use of this posterior approach for renal artery ligation is safe and effective, even with large renal tumors with multiple collaterals and/or lymph nodes making the identification of the renal artery difficult.     

Liver transplantation in a patient with complex anomaly of the inferior vena cava

Background

After the introduction of noninvasive imaging exams, congenital anomalies of the inferior vena cava (IVC) have become more commonly recognized. We report the first successful orthotopic liver transplantation (OLT) performed in an asymptomatic adult with complex IVC anomaly: duplication of the infrarenal IVC, azygos continuation of the IVC, agenesia of the hepatic portion of the IVC and presence of several anomalous veins communicating the common iliac vein and the IVC of one side with the contralateral side.

Methods

This complex anomaly was diagnosed with a venous abdominal angio CT.

Results

At liver transplantation, the short suprahepatic portion of the IVC was identified and clamped. The right, middle, and left hepatic veins were sectioned and joined in a single, wide cuff, using venoplasty. This single orifice was anastomosed to the suprahepatic IVC of the new liver. No venovenous bypass was employed. The patient had an uneventful postoperative course. A post transplantation venous abdominal angio CT showed normal blood flow at the anastomosis of the hepatic veins of the receptor and the IVC of the new liver.

Conclusions

This report is important to alert liver transplant teams of the possibility of complex IVC in asymptomatic adult individuals. Identification of these anatomical anomalies is vital to reduce the risk of serious hemorrhage and other operative complications during OLT.     

Robotic renal surgery for renal cell carcinoma with inferior vena cava thrombus

Surgical management of renal cell carcinoma (RCC) with inferior vena cava (IVC) thrombus is inherently complex, posing challenges for even the most experienced urologists. Until the mid-2000s, nephrectomy with IVC thrombectomy was exclusively performed using variations of the open technique initially described decades earlier, but since then several institutions have reported their robotic experiences. Robotic IVC thrombectomy was initially reported for level I and II thrombi, and more recently in higher-lever III thrombi. In general, the robotic approach is associated with less blood loss and shorter hospital stays compared to the open approach, low rates of open conversion in reported cases, relatively low rates of high-grade complications, and favorable overall survival on short-term follow-up in limited cohorts. Operative times are longer, costs are significantly higher, and left-sided tumors always require intraoperative repositioning and usually require preoperative embolization. To date, criteria for patient selection or open conversion have not been defined, and long-term oncologic outcomes are lacking. While the early published robotic experience demonstrates feasibility and safety in carefully selected patients, longer-term follow-up remains necessary. Patient selection, indications for open conversion, logistics of conversion particularly in emergent settings, necessity and safety of preoperative embolization, the value proposition, and long-term oncologic outcomes must all be clearly defined before this approach is widely adopted.

Multidisciplinary management of testicular cancer complicated by thrombosis of the inferior vena cava: a case report

Introduction: Testicular cancer is a rare disease, most commonly seen in young adults. It represents 1% of solid cancers in men. Inferior vena cava (IVC) thrombosis remains a rare complication of testicular cancer and is often associated with a high risk of pulmonary embolism (PE).

Case report: The authors report a case of a 26-year-old man presenting with advanced testicular cancer, left-sided retroperitoneal metastasis and parietal infiltration of the IVC complicated with thrombosis of the left iliac vein and the IVC, both responsible for PE.

Discussion: A multidisciplinary management which included curative excision of the lesions, placement of a temporary IVC filter and adjuvant chemotherapy permitted an optimal approach. No complications occurred and the post-operative healing was uneventful. No recurrences were observed on the long-term follow-up.

Conclusions: IVC Thrombosis is a rare complication that should be taken into consideration when diagnosing testicular cancer. Prompt diagnosis is crucial to minimize the risk of PE which can be life-threatening.     

Calcific thrombi of the inferior vena cava in infants and children.

Calcified caval thrombus should be considered in any infant or child where calcifications are noted in the high right retroperitoneal area on plain x-rays of the abdomen. Although typically bullet-shaped in configuration, the calcium distribution in the neonate may be atypical or incompletely developed, suggesting neuroblastoma. Definitive diagnosis can be made by inferior vena cavagram. As no deaths or complications have been attributed to the lesion in the cases thus far reported, no specific treatment is recommended.     

Thymic carcinoma with tumor thrombus into the superior vena cava

Tumor thrombus into the vena cava have been reported in cases with renal cell carcinoma, thyroid tumor and in those with thymoma. These tumors are frequently invasive and continuous from the main tumor that shows direct vessel wall invasion. Here, we report a case of thymic carcinoma with superior vena cava syndrome, which was caused by a tumor thrombus in the superior vena cava without vessel wall invasion. The main mediastinal tumor did not show innominate vein invasion, and the superior vena cava syndrome was a result of separate tumor thrombus that was free of vessel wall invasion. The tumor thrombus could be removed through a simple venotomy. To prevent stenosis in the superior vena cava and the left innominate vein, we used a pericardial patch to close the venotomy site.     

Clinical outcome of surgical management for patients with renal cell carcinoma involving the inferior vena cava

BACKGROUND: The objective of this study was to evaluate the clinical outcome after surgical management of renal cell carcinoma (RCC) extending to the inferior vena cava (IVC). METHODS: This study included a total of 55 patients (41 men and 14 women; mean age, 59.3 years) with RCC (39 right- and 16 left-sided tumors) involving the IVC, who underwent radical nephrectomy and tumor thrombectomy between 1983 and 2005 at a single institution in Japan. The level of thrombus was classified as follows: level I, infrahepatic; level II, intrahepatic; level III, suprahepatic; and level IV, extending to the atrium. Clinicopathological data from these patients were retrospectively reviewed to identify factors associated with survival. RESULTS: There were 11 and 18 patients who were diagnosed as having lymph node and distant metastases, respectively. Twenty-two patients had tumor thrombus in level I, 20 in level II, 10 in level III, and 3 in level IV. Pathological examinations demonstrated that 34 and 21 patients had clear cell carcinoma and non-clear cell carcinoma, respectively, 42, 9 and 4 were pT3b, pT3c and pT4, respectively, and 6, 35 and 14 were Grades 1, 2 and 3, respectively. Cancer-specific 1-, 3- and 5-year survival rates of these 55 patients were 74.5%, 51.4% and 30.3%, respectively. Among several factors examined, clinical stage (P = 0.047), lymph node metastasis (P = 0.016), histological subtype (P = 0.034) and tumor grade (P < 0.001) were significantly associated with cancer-specific survival by univariate analysis. Furthermore, multivariate analysis demonstrated clinical stage (P = 0.037) and tumor grade (P < 0.001) as independent predictors of cancer-specific survival irrespective of other significant factors identified by univariate analysis. CONCLUSIONS: In patients with RCC involving the IVC, biological aggressiveness characterized by tumor grade rather than tumor extension would have more potential prognostic importance; therefore, more intensive multimodal therapy should be considered in patients with high grade RCC with tumor thrombus extending into the IVC.

Resection of the abdominal inferior vena cava for complicated renal cell carcinoma with tumour thrombus

OBJECTIVE: To describe our experience of excising the inferior vena cava (IVC) without a graft; en bloc resection of a renal cell carcinoma (RCC) with the renal vein and vena cava tumour thrombus and a segment of the entire abdominal IVC is technically feasible, but traditionally, after resection, attempts are made to restore continuity with the use of synthetic or homologous venous grafts. PATIENTS AND METHODS: Between May 1997 and September 2004, 60 patients (mean age 62 years) underwent surgical resection of a renal tumour with a thrombus extending into the IVC. To resect the entire evident tumour, excision of the affected portion of the IVC was required in three patients (5%); the IVC was not reconstructed. RESULTS: The three patients were aged 38, 39 and 74 years; the mean operative duration was 5.88 h, the mean (range) estimated blood loss was 833 (500-1000) mL, the mean number of blood units transfused was 3.3 (0-7) units, and the mean follow-up was 24 months. The course after surgery was uneventful; specifically, none of the patients had a venous thrombosis or a pulmonary embolus. CONCLUSIONS: RCC has a propensity to invade the renal vein and IVC. Occasionally the thrombus invades the wall of the IVC and complete removal requires excision of a circumferential portion of the IVC; this can be done safely without a graft.     

Transitional cell carcinoma of the renal pelvis forming tumor thrombus in the vena cava

A 47-year-old man presented with a left renal incidentaloma without hematuria. The tumor was complicated by inferior vena cava (IVC) thrombus extending from Th11 to L4. A temporary IVC filter was introduced prior to surgery. A midline incision was used to perform a left radical nephrectomy and en bloc lymphadenectomy with excision of the inferior vena cava from above the level of the left renal vein to 2.5 cm above the confluence of the common iliac veins. The pathological diagnosis was invasive transitional cell carcinoma. The tumor thrombus consisted of transitional cell carcinoma that histologically invaded the walls of the IVC. He died of cancer 17 months after the operation for the liver metastases. This is the 18th case report of such a presentation in the literature.
