Abstract
Two dogs with anorexia and rapid weight loss were referred to our hospital due to a right renal mass and several pulmonary nodules. Both dogs underwent needle core biopsy of the mass, followed by transarterial chemoembolisation of the renal mass. A catheter was inserted from the femoral artery and advanced into the right renal artery. A suspension of carboplatin (100 mg/m2 ) and equivalent lipiodol was administered via the inserted multipurpose catheter. Immediately after, under fluoroscopic guidance, pulse injections of small amounts of gelatin particles (diameter 1 mm) dissolved in iohexol were administered until complete embolisation of the renal artery. Histopathologic diagnosis was renal cell carcinoma in both dogs. Clinical signs improved for 134 and 358 days after transarterial chemoembolisation. In addition, postoperative radiographs demonstrated a decrease in the tumour size. The dogs died 215 and 525 days after the initial evaluation, respectively. As a palliative treatment, transarterial chemoembolisation might help reduce the tumour volume and improve the quality of life in dogs with renal cell carcinoma and distant metastases.

Adjuvant instant preoperative renal artery embolization facilitates the radical nephrectomy and thrombectomy in locally advanced renal cancer with venous thrombus: a retrospective study of 54 cases. World J Surg Oncol 2020; 18:206. [PMID: 32795311 PMCID: PMC7427865 DOI: 10.1186/s12957-020-01985-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 07/31/2020] [Indexed: 01/31/2023] Open
Abstract
Background The role of renal artery embolization (RAE) in the therapeutic armamentarium is always controversial. The present study aimed to assess the safety and the surgical outcomes of the instant renal artery embolization (I-RAE) prior to nephrectomy and thrombectomy in patients with locally advanced renal cell carcinoma (RCC) with venous thrombus. Methods We performed a retrospective analysis of 54 patients treated with nephrectomy and thrombectomy between January 2012 and January 2019. Twenty-four patients were treated with I-RAE before surgery. Thirty patients received surgery alone (non-RAE group). The patient demographics, operation time, blood loss, transfusion requirements, complications, and other surgical parameters were analyzed between the two groups. Results The mean tumor size in the I-RAE group was significantly larger than that in the non-RAE group (11.1 cm versus 7.9 cm; p = .001). The mean estimated blood loss was significantly lower in the I-RAE group compared to that in the non-RAE group (596 ml versus 827 ml; p = .015), and the patients in the non-RAE group were more likely to receive blood transfusion (red blood cell, RBC units, 4 U versus 6 U, p = .025; plasma volume, 200 ml versus 400 ml, p = .01). No differences were found in operative duration, ICU stay, perioperative complications, and length of postoperative hospitalization. Conclusions Instant preoperative adjuvant renal artery embolization (I-RAE) is a safe technique. It facilitates nephrectomy and thrombectomy by reducing blood loss, transfusion requirements, and complications of delayed operations, providing urologists with a reliable option for treatment of locally advanced RCC with tumor thrombus.

Abstract
The medical reports of 113 patients operated upon for renal tumors were retrospectively reviewed to assess the value of preoperative embolization. Coils or ethanol were used preoperatively in 55 patients while 58 patients underwent nephrectomy without embolization. The tumors were staged according to the TNM and the Robson staging classification. T1 and T2 tumors as well as T3 and T4 tumors were grouped together for statistical evaluation. There was no significant difference in intraoperative blood loss, operation time and survival rate between patients undergoing preoperative embolization and those who had only nephrectomy. Duration of hospital stay was always longer in the preoperatively embolized group. Preoperative embolization of renal tumors neither improved the patients' outcome nor reduced the surgical risk. Robson's classification, stage III/IV, did not show any significant differences for embolized patients or for those nephrectomized without embolization.

Abstract
The diagnosis of renal cell carcinoma is accompanied by intravascular tumor thrombus in up to 10% of cases, of which nearly one-third of patients also have concurrent metastatic disease. Surgical resection in the form of radical nephrectomy and caval thrombectomy represents the only option to obtain local control of the disease and is associated with durable oncologic control in approximately half of these patients. The objective of this clinical review is to outline the preoperative evaluation for, and operative management of patients with locally advanced renal cell carcinoma with venous tumor thrombi involving the inferior vena cava. Cornerstones of the management of these complex patients include obtaining high-quality imaging to characterize the renal mass and tumor thrombus preoperatively, with further intraoperative real-time evaluation using transesophageal echocardiography, careful surgical planning, and a multidisciplinary approach. Operative management of patients with high-level caval thrombi should be undertaken in high-volume centers by surgical teams with capacity for bypass and invasive intraoperative monitoring. In patients with metastatic disease at presentation, cytoreductive nephrectomy and tumor thrombectomy may be safely performed with simultaneous metastasectomy if possible. In the absence of level one evidence, neoadjuvant targeted therapy should continue to be viewed as experimental and should be employed under the auspices of a clinical trial. However, in patients with significant risk factors for postoperative complications and mortality, and especially in those with metastatic disease, consultation with medical oncology and frontline targeted therapy may be considered.

Abstract
Renal arterial embolization (RAE) performed for the treatment of renal masses has been proven to be a safe and effective technique, with several decades of experience. RAE is well tolerated with few complications, particularly if the time interval from embolization to surgery is reduced to less than 48 hours. Review of the literature suggests that RAE is also extremely effective for palliation of symptoms in the setting of nonoperative advanced stage renal cell carcinoma. In addition, this technique plays a large role in the management of angiomyolipomas that are symptomatic or at risk of spontaneous rupture. To date, RAE has not been evaluated in a randomized controlled setting, which has contributed to its underutilization. All of these potential benefits warrant the need for prospective studies for further validation.

Abstract
OBJECTIVE Renal angioinfarction (RAI) has been used for various indications in the management of renal tumors. While historically used for palliation of local symptoms (pain or hematuria), this technique has theoretical use in facilitating radical nephrectomy by allowing early ligation of the renal vein, decreasing blood loss and creating edema in resection planes. A common impediment to embolization is the development of postembolization syndrome (PES), which has been reported to have an incidence as high as 89%. This study reports the authors' experience with RAI as a safe palliative and adjunctive procedure over 4 years. MATERIAL AND METHODS From 2008 to 2011, 113 patients underwent complete RAI at Washington Hospital Center for palliative or adjunctive therapy by an interventional radiologist. Procedures were performed in a radiology suite using mild sedation with vascular access obtained by femoral artery puncture. RAI was performed by subsegmental injection of polyvinyl alcohol particles. RESULTS All 113 patients underwent successful RAI with confirmation of total arterial flow ablation via postprocedure arteriogram: 38 underwent embolization for preoperative adjunctive therapy, 34 for palliation of renal mass, 36 for trauma/hemorrhage and five for symptomatic renal artery pseudoaneurysm after partial nephrectomy. PES occurred in 33 out of 75 patients (44.0%), with symptomatic PES in only two patients (2.6%). No major complications (>Clavien grade III) occurred. Thirty-eight patients were excluded from analysis as they underwent radical nephrectomy within 24 h, preventing accurate assessment of PES. CONCLUSIONS RAI is a safe and reliable procedure for palliation of renal masses, as an adjunctive procedure for radical nephrectomy, and for conservative management of renal hemorrhage or aneurysm. PES occurs in relatively few patients, with no major complications, and should not impede clinical consideration of this procedure.

Abstract
Transcatheter intraarterial therapies have proved valuable in the battle against primary and secondary hepatic malignancies. The unique aspects of all such therapies are their reduced toxicity profiles and highly effective tumor responses. These unique characteristics coupled with their minimally invasive nature provide an attractive therapeutic option in patients who may have previously had few alternatives. The concept of all catheter-based intraarterial therapies is to selectively deliver anticancer treatment to tumor(s). These therapies, which include transarterial embolization, intraarterial chemoinfusion, transarterial chemoembolization with or without drug-eluting beads, and radioembolization with use of yttrium 90, inflict lethal insult to tumors while preserving normal hepatic parenchyma. This is possible because hepatic neoplasms preferentially derive their blood supply from an arterial source while the majority of noncancerous liver is supplied by the portal vein. As part of the interventional oncology review series, in this article we describe the rationale behind each of these transcatheter therapies and provide a review of the existing medical literature.

Abstract
OBJECTIVES To review our experience with radical nephrectomy and inferior vena cava thrombectomy (RNIVCT) to determine the utility of preoperative embolization. Preoperative embolization has been used as an adjunctive procedure to facilitate surgical resection of complex renal tumors. METHODS From 1990 to 2007, 225 patients with renal tumors and inferior vena cava thrombus underwent RNIVCT, including 135 patients who had undergone preoperative renal artery embolization and 90 patients who had not. The effect of embolization on perioperative morbidity and mortality, transfusion requirements, blood loss, and operative time was analyzed by comparing the 2 groups. RESULTS The mean primary tumor size was similar in both groups; however, 67% of the RNIVCT embolization group vs 48% of the nonembolization group had retrohepatic (level III) or supradiaphragmatic (level IV) thrombus extension (P = .032). The RNIVCT embolization patients had a greater median number of perioperative units transfused (8 vs 4; P = .001), a longer operative time (390 vs 313 minutes; P < .001), more postoperative complications (43% vs 29%; P < .001), a longer intensive care unit stay (2 vs 0.5 days), and increased perioperative mortality (13% vs 3%; P = .017). No differences were found in intraoperative complications or length of hospitalization. Multivariate analysis showed a fivefold greater risk of perioperative death (adjusted odds ratio 5.5; P = .029) and a trend toward increased blood transfusion (regression coefficient 3.9; P = .08) with preoperative embolization. CONCLUSIONS The results of our study have shown that routine preoperative renal artery embolization in patients undergoing RNIVCT does not provide any measurable benefit in reducing blood loss or complications and was associated with increased major perioperative complications and mortality.

Abstract
Currently, there is no widespread use of percutaneous renal artery embolisation (PRAE) as a pre-operative treatment in the management of renal cell carcinoma (RCC). There is also a scarcity of studies concerning the potential benefits of this procedure. All patients with RCC who underwent pre-operative PRAE before nephrectomy (n = 227) and all patients solely undergoing surgery (n = 607) at our institution from 1992 to 2006 were included. Information on techniques used, perioperative transfusion requirements, pathological and clinical variables, acute toxicity and complications were obtained from a retrospective review of medical records. Propensity modelling techniques were used to compare cancer-specific survival (CSS) and overall survival (OS) in both groups. Propensity scores were calculated from a logistic matching model including age, gender, clinical tumour size, grading, pN stage, cM stage, pT stage, histology and microvascular invasion. This resulted in 189 matches. The mean follow-up of the entire group of matched patients was 81 months. The 5-year actuarial CSS and OS for the total group of matched patients was 80.8% and 73.9%, respectively. CSS and OS did not show any significant differences between the matched treatment groups. There were no statistical differences in surgical complications between all patients treated with pre-operative PRAE (n = 227) and all patients without PRAE (n = 607), except for blood transfusion (61% vs 24%; p<0.01). Symptoms of post-embolization syndrome, including lumbar pain, fever, nausea, hypertension and macroscopic haematuria, were reported by 202 patients (89%), in most cases being mild and self-limited. There is no conclusive evidence that pre-operative PRAE provides survival benefits in the management of surgically resected RCC.

Abstract
PURPOSE To assess the degree of renal necrosis and the leakage of absolute ethanol by using two methods: transcatheter renal artery embolization (TAE) and TAE performed with a closed renal circuit (CRC) (TAE/CRC), both performed by using ethanol and iodized oil, in a pig model. MATERIALS AND METHODS All animal experiments were conducted in accordance with our university guidelines for animal care and experimentation. Fourteen pigs were classified in two groups: standard TAE and TAE/CRC groups. In the TAE/CRC group, the renal artery and vein were occluded with balloon catheters; in the TAE group, only the renal artery was occluded. An emulsion of absolute ethanol (0.5 mL per kilogram of body weight) and iodized oil (emulsion ratio, 4:1) was injected in the renal artery in both groups. In the TAE/CRC group, we aspirated the blood containing the emulsion via the renal vein during arterial infusion. We measured the ethanol concentrations of the systemic circulation. Four days after embolization, the kidneys in both groups were removed and histopathologic examination was performed and results were compared. RESULTS The mean systemic ethanol concentration was less than 0.1 mg/mL in the TAE/CRC group and 0.28 mg/mL +/- 0.15 (standard deviation) in the TAE group (P < .002). In both groups, about 90% of the kidney was shown histopathologically to have undergone coagulation necrosis (no significant difference). The frequency of venous thrombus formation was significantly lower (P = .009) in the TAE/CRC group. CONCLUSION TAE/CRC dramatically reduces ethanol leakage to the systemic circulation without a decrease in embolization effect in the normal swine kidney, and it also reduces the likelihood of venous thrombus formation.

Abstract
The aim of this study is to review the role and technique of renal artery embolisation (RAE), and assess its effectiveness in the palliative treatment of unresectable or inoperable renal cell carcinoma (RCC) in our institution. The study group consisted of 19 consecutive patients (16 male, 3 female; age range 47-87 years) who underwent palliative RAE for the treatment of renal carcinoma between January 2000 and December 2005. Unresectable disease was present in 11 patients (3 stage IVa, 8 stage IVb). Potentially resectable disease was present in 8 patients (4 stage II, 1 stage IIIa, 1 stage IIIb, 2 stage IIIc); however, these patients were unfit for surgery for other reasons. 13 patients presented with haematuria, which was gross in 7 patients. Nine patients complained of flank pain. RAE was performed using polyvinyl alcohol or embosphere particles, metallic coils and, in some cases, absolute alcohol was necessary. At the time of analysis, 12 patients had died while 7 patients were still alive, with an overall median survival for the study group of 6 months. In the 7 patients with transfusion dependant gross haematuria, there was stabilization of the haemoglobin level post-embolisation. In the 9 patients who presented with flank pain, symptoms improved or resolved in 8 patients. The median length of hospital stay for the 18 patients who were discharged was 5.0 days. RAE is a safe and tolerable management option for patients with inoperable or unresectable renal carcinoma as a means of palliation of local symptoms and improving clinical status, with low morbidity and shorter hospital stay.

Abstract
OBJECTIVE To review current indications and techniques for renal artery embolization (RAE) and more specifically to review cases of RAE before nephrectomy for treating patients with a large renal mass. PATIENTS AND METHODS All RAEs done at our institution between May 1993 and December 2005 were reviewed. Patients were identified using a database assembled by the Division of Cardiovascular Interventional Radiology. Indications, techniques and RAE-related complications were then obtained from a retrospective review of medical records. Additional data for patients undergoing preoperative infarction were acquired, including estimated blood loss (EBL), transfusion requirement, pathological size, subtype, grade, stage, and level of tumour thrombus if present. RESULTS In all, there were 121 RAEs, 69 in males and 52 in females (mean age 57.6 years, range 11-89). Metallic microcoils were the most often used embolization agent, followed by acrylic microspheres (embospheres), polyvinyl alcohol particles, absolute ethanol, and Gelfoam (Pharmacia & Upjohn, USA). The most common indication for RAE was infarction before nephrectomy (54.5%). Other indications included symptomatic angiomyolipomas, palliation of unresectable renal cancer, haemorrhage, perinephric bleeding in end-stage renal disease, vascular lesions, malignant hypertension, and sequelae of end-stage renal disease. RAE-associated complications including coil migration, incomplete embolization, and groin haematoma (in 5.0%). Symptoms of post-infarction syndrome were common, with 74.4% of patients having flank pain, nausea, or vomiting; the vast majority of these symptoms were mild and self-limited. In patients having nephrectomy after RAE the median (range) interval from RAE was 2 (0-78) days. The mean tumour size was 11.2 (3.5-25) cm and 46% of patients had tumour thrombus present in either the renal vein or inferior vena cava (IVC). The mean (median) overall EBL in patients having nephrectomy after RAE was 1048 (725) mL. The mean transfusion requirement over the course of hospitalization was 3.9 units of packed red blood cells. CONCLUSIONS RAE is a safe and effective therapeutic tool for many urological, renal and vascular conditions. Its use has increased at our institution due to improved techniques, embolization materials, and our increasing use of RAE as an adjuvant procedure for patients requiring nephrectomy with or without IVC thrombectomy. There are many potential operative advantages for patients having RAE before surgery, with minimal morbidity. It is likely that the lack of prospective randomized trials is the primary reason why it is underutilized in the preoperative setting.

Abstract
Embolisation has become an accepted modality of cancer treatment in patients with a variety of clinical scenarios. It is commonly used in clinical practice in the treatment of hepatocellular carcinoma, hepatic metastases from colorectal cancer and neuroendocrine tumours, and renal cell carcinoma. This review summarizes the current evidence for the efficacy of embolotherapy in these clinical settings, together with the associated complications.

Abstract
OBJECTIVE To evaluate the efficacy of transcatheter arterial embolization (TAE) in patients with unresectable renal cell carcinoma (RCC) and distant metastasis at the time of diagnosis. PATIENTS AND METHODS The study included 54 patients with histologically defined RCC (by biopsy in 28 and autopsy in 26) who were unable to undergo nephrectomy mainly because their performance status was poor (score > or = 2). The patients were classified into two groups; 24 patients who underwent TAE with ethanol and 30 patients who did not. The two groups were compared for several clinical factors, mainly focusing on the prognosis. RESULTS There were no significant differences in the clinical factors, including performance status, tumour diameter, vascular invasion, lymph node involvement, adjuvant therapy, metastatic organs or the number of metastases between the groups. However, the proportion of patients with para-neoplastic signs in those undergoing TAE was greater than that in those not, and the difference was significant (chi squared 0.35, P < 0.05). The median survival of the two groups was 229 days (TAE) and 116 days (no TAE). The 1-, 2- and 3-year survival rates in the TAE group were 29%, 15% and 10%, respectively, and in those not undergoing TAE were 13%, 7% and 3%, respectively. Those undergoing TAE had a significantly better prognosis than those who did not (P = 0.019). The adverse effects in patients undergoing TAE with ethanol included fever, back pain on the affected side, nausea and vomiting, but all the patients recovered from these adverse effects. CONCLUSION TAE with ethanol is a safe and effective treatment for patients with unresectable disseminated RCC and a poor performance status; TAE with ethanol not only induces ablation of the primary tumour, but also prolongs survival.

Abstract
A series of 474 patients with renal cell carcinoma (RCC), who had radical nephrectomy during a period of 15 years, was studied to assess the prognostic significance of various pathologic parameters (tumor stage [pT], lymph node status, metastasis, tumor grade, venous involvement) and value of preoperative embolization of renal artery. There were: 20 (4%) pT1, 204 (43%) pT2, 245 (52%) pT3, and 5 (1%) pT4 patients. All 474 patients underwent nephrectomy including a group of 118 (25%) patients (24 pT2, 90 pT3, and 4 pT4) who underwent preoperative embolization of the renal artery. To compare treatment outcomes in embolized patients with RCC, a group of 116 (24%) nonembolized patients with RCC was selected. This group was matched for sex, age, stage, tumor size, and tumor grade, with the embolized patients (p<0.01). All important prognostic factors were studied as to their influence on survival by the treatment group. The overall 5- and 10-year survival was 62% and 47%, respectively. The 5- and 10-year survival rates were significantly better (p<0.01) for patients with pT2 than for those with pT3 tumors (79% vs. 50% and 59% vs. 35%, respectively). Involvement of regional lymph nodes (N+) was an important prognostic factor for survival in patients with pT3 tumors. The 5-year survival for pT3 N+ was 39%, compared with 66% in those with pT3N0 (p<0.01). Preoperative embolization was also an important factor influencing survival. The overall 5- and 10-year survival for 118 patients embolized before nephrectomy was 62% and 47%, respectively, and it was 35% and 23%, respectively, for the matched group of 116 patients treated with surgery alone (p = 0.01). The most important finding of this study was an apparent importance of preoperative embolization in improving patients' survival. This finding needs to be interpreted with caution and confirmed in a prospective randomized trial.

Abstract
PURPOSE The authors evaluated the effectiveness of preoperative ethanol renal artery embolization in reducing transfusion requirements during nephrectomy for renal cell carcinoma. PATIENTS AND METHODS Of 93 consecutive patients who underwent nephrectomy for renal cell carcinoma from 1980 to 1990, 24 patients underwent embolization within 24 hours of nephrectomy. Finding in this group were compared with those in 69 control patients who underwent surgery without preoperative embolization. RESULTS Embolized tumors were larger than nonembolized ones (mean volume, 595 vs 257 mL) (P < .05). Patients with large hypervascular tumors (volume over 250 mL) who underwent complete embolization received significantly smaller mean blood transfusion volumes than control patients (250 vs 800 mL; P = .01). The transfusion volume associated with incomplete embolization was higher than that associated with no embolization. CONCLUSION Complete alcohol embolization significantly reduces the volume of blood transfused during nephrectomy for large hypervascular renal cell carcinomas, and incomplete embolization is associated with larger transfusions. Preoperative embolization must be complete and should be performed more widely.

Abstract
Planned delayed nephrectomy after preoperative ethanol infarction was done in 6 patients with renal carcinoma. Three patients had intracaval extension of tumor, 2 had renal vein but no vena caval extension and 1 had no renal vein or vena caval involvement. Nephrectomy was delayed 22 to 44 days after embolization. In the patients with inferior vena caval extension shrinkage of tumor thrombus after embolization allowed for easier surgical resection. Furthermore, delay of nephrectomy after preoperative infarction was of value in improving the clinical status of high risk patients.

Abstract
The literature concerning embolization of the renal artery in patients with renal cell carcinoma is reviewed. Based on this review it is concluded that the method is useful in this patient group as it will facilitate the surgical procedure if nephrectomy is performed afterwards. Used as a palliative method, embolization reduces haematuria. It was not possible to draw conclusions concerning survival rates or eventual immuno-stimulating effects of embolization.

Abstract
The Interventional Radiology Group of the Royal College of Radiologists sent a questionnaire to major hospitals in the United Kingdom in 1982 and 1987 in order to assess the impact of the introduction and growth of interventional procedures on patient management over the 5-year period and to consider the implications of these data for the future staffing and equipment requirements of radiology departments. In the 194 hospitals correctly completing the most recent survey, a total of 30,794 interventional procedures were performed in a 12 month period, representing an overall increase of 116% since the previous survey of 1982.

Abstract
Neoplastic tissue was obtained at operation from 10 renal cell carcinomas, from the adjacent 'normal' kidney in 6 cases and from 1 other normal kidney. The biopsies were snap frozen in liquid nitrogen and sections were subsequently stained with monoclonal antibodies against major histocompatibility complex (MHC) antigens, class I and II, and several types of mononuclear cell, by the indirect immunoperoxidase method. The degree of staining or the number of cells stained was estimated as heavy 4, through moderate 3, few 2, occasional 1, or nil 0. MHC Ag were consistently expressed, grade 2-4, by the glomeruli and proximal convoluted tubules of normal kidney, but were absent in 8 of 10 carcinomas. There was a grade 3-4 mononuclear cell infiltration in the stroma of normal kidney and between the carcinoma cells which was composed principally of macrophages. However in the two carcinomas expressing MHC Ag there was also a grade 2-3 infiltration with T lymphocytes. The absence of MHC Ag on carcinoma cells mitigates against attempts to potentiate the patient's immune response to his tumour, e.g. by renal artery embolisation.

Abstract
Sodium tetradecyl sulfate is a sclerosing agent used currently as therapy for varicose veins. Animal experiments have demonstrated this drug to be a useful agent for renal tissue destruction. We have used sodium tetradecyl sulfate with or without steel coils for preoperative renal devascularization in 6 patients with advanced renal adenocarcinoma. In all patients sodium tetradecyl sulfate effectively caused renal infarction and was tolerated well. No complications were associated with the use of this agent. Sodium tetradecyl sulfate is an efficient fluid embolic agent that can be a useful adjunct to nephrectomy in selected cases.
