Abstract
Vascular interventions are an important and established tool in the management of the oncology patient. The goal of these procedures may be curative, palliative or adjunctive in nature. Some of the common vascular interventions used in oncology include transarterial embolisation or chemoembolisation, selective internal radiation therapy, chemosaturation, venous access lines, superior vena cava stenting and portal vein embolisation. We provide an overview of the principles, technology and approach of vascular techniques for tumour therapy in both the arterial and venous systems. Arterial interventions are currently mainly used in the management of hepatocellular carcinoma. Transarterial embolisation, chemoembolisation and selective internal radiation therapy deliver targeted catheter-delivered treatments with the aim of reducing tumour burden, controlling tumour growth or increasing survival in patients not eligible for transplantation. Chemosaturation is a regional chemotherapy technique that delivers high doses of chemotherapy directly to the liver via the hepatic artery, while reducing the risks of systemic effects. Venous interventions are more adjunctive in nature. Venous access lines are used to provide a means of delivering chemotherapy and other medications directly into the bloodstream. Superior vena cava stenting is a palliative procedure that is used to relieve symptoms of superior vena cava obstruction. Portal vein embolisation is a procedure that allows hypertrophy of a healthy portion of the liver in preparation for liver resection. Interventional radiology-led vascular interventions play an essential part of cancer management. These procedures are minimally invasive and provide a safe and effective adjunct to traditional cancer treatment methods. Appropriate work-up and discussion of each patient-specific problem in a multidisciplinary setting with interventional radiology is essential to provide optimum patient-centred care.

Long-term impact of replaced right hepatic artery resection in pancreaticoduodenectomy. Updates Surg 2024:10.1007/s13304-024-01811-9. [PMID: 38526700 DOI: 10.1007/s13304-024-01811-9] [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: 11/20/2023] [Accepted: 03/04/2024] [Indexed: 03/27/2024]
Abstract
The clinical impact of replaced right hepatic artery (rRHA) resection during pancreaticoduodenectomy (PD) has not been thoroughly investigated. We therefore assessed the short- and long-term effects of rRHA resection during PD, with special reference to alterations in the volumetric profile of the liver. Patients with rRHA were divided into two groups based on the presence (R group) or absence (nR group) of resection. The nR group included cases of rRHA resection and reconstruction. We compared the postoperative short-term complications and detailed liver volume profile by CT volumetry in the long term between the R and nR groups. Forty-seven patients were eligible for the analyses of short-term outcomes (R: n = 7, nR: n = 40), and no marked difference was observed in the incidence of short-term postoperative complications. The patient cohort for the long-term investigations included 34 cases (R: n = 6, nR: n = 28), excluding patients with early recurrence. There was no significant difference in the preoperative liver volume profiles between the two groups. At 12 postoperative months, although the whole liver (WL) volume did not significantly change in either group, the ratio of the volume of the anterior/posterior sections significantly increased in the R group (R: pre- vs. 12 months, 1.01 vs. 1.28, p < 0.05; nR: pre- vs. 12 months, 1.40 vs. 1.33, p = 0.99). Long-term rRHA resection did not significantly affect the WL volume with alteration of the liver volumetric profile of each section.

Compensatory hypertrophy of the liver after external beam radiotherapy for primary liver cancer. Strahlenther Onkol 2018; 194:1017-1029. [PMID: 30105451 DOI: 10.1007/s00066-018-1342-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2017] [Accepted: 07/14/2018] [Indexed: 02/08/2023]
Abstract
PURPOSE We investigated whether external beam radiotherapy (EBRT) could induce compensatory liver hypertrophy in liver cancers and assessed related clinical factors. METHODS A total of 82 consecutive patients receiving EBRT for hepatocellular carcinoma (n = 77) or cholangiocarcinoma (n = 5) from April 2012 to June 2014 were recruited and divided into two subgroups according to tumor location in the right or left lobe. The left lateral and right lobes were considered as unirradiated volumes accordingly. Total liver volume (TLV), nontumor liver volume (NLV), left and right lobe whole volume (LLWV and RLWV, respectively), volume of liver irradiated < 30 Gy (V< 30 Gy), Child-Pugh (CPS) score, future liver remnant (FLR) ratio, and percentage of FLR hypertrophy from baseline (%FLR) were assessed. RESULTS In the right lobe group, %FLR hypertrophy and LLWV increased significantly at all follow-ups (p < 0.001). %FLR hypertrophy steadily increased until the fourth follow-up. Multivariate analysis showed that the factor associated with maximum %FLR hypertrophy was tumor extent (upper or lower lobe vs. both lobes; p = 0.022). Post-RT treatments including transarterial chemoembolization or hepatic arterial infusion chemotherapy were associated with a CPS increase ≥ 2 (p = 0.002). Analysis of the RT only subgroup also showed a significant increase of %FLR until the fourth follow-up (p < 0.001). In the left lobe group, %FLR hypertrophy and RLWV showed no significant changes during follow-up. CONCLUSION Significant compensatory hypertrophy of the liver was observed, with a steady increase of %FLR hypertrophy until the fourth follow-up (median: 396 days). Locally advanced tumors extending across the upper and lower right lobe were a significant factor for compensating hypertrophy after EBRT.

Br J Surg 2016; 103:1768-1782. [PMID: 27633328 DOI: 10.1002/bjs.10290] [Citation(s) in RCA: 103] [Impact Index Per Article: 12.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2016] [Revised: 07/04/2016] [Accepted: 07/06/2016] [Indexed: 12/12/2022]
Abstract
BACKGROUND Discussion is ongoing regarding whether associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) or portal vein occlusion is better in staged hepatectomy. The aim of this study was to compare available strategies using a two-stage approach in extended hepatectomy. METHODS A literature search was performed in MEDLINE, Scopus, the Cochrane Library and Embase, and additional articles were identified by hand searching. Data from the international ALPPS registry were extracted. Clinical studies reporting volumetric changes, mortality, morbidity, feasibility of the second stage and tumour-free resection margins (R0) in two-stage hepatectomy were included. RESULTS Ninety studies involving 4352 patients, including 320 from the ALPPS registry, met the inclusion criteria. Among these, nine studies (357 patients) reported on comparisons with other strategies. In the comparison of ALPPS versus portal vein embolization (PVE), ALPPS was associated with a greater increase in the future liver remnant (76 versus 37 per cent; P < 0·001) and more frequent completion of stage 2 (100 versus 77 per cent; P < 0·001). Compared with PVE, ALPPS had a trend towards higher morbidity (73 versus 59 per cent; P = 0·16) and mortality (14 versus 7 per cent; P = 0·19) after stage 2. In the non-comparative studies, complication rates were 39 per cent in the PVE group, 47 per cent in the portal vein ligation (PVL) group and 70 per cent in the ALPPS group. After stage 2, mortality rates were 5, 7 and 12 per cent respectively. CONCLUSION ALPPS is associated with greater future liver remnant hypertrophy and a higher rate of completion of stage 2, but this may be at the price of greater morbidity and mortality.

Limits of and Complications after Embolization of the Hepatic Artery and Portal Vein to Induce Segmental Hypertrophy of the Liver: A Large Mini-Pig Study. Eur Surg Res 2016; 57:155-170.

Abstract
Background: The aim of this study was to compare arterial embolization (AE) with portal vein embolization (PVE) for the induction of segmental hypertrophy regarding procedural efficacy, safety and outcome. Methods: A total of 29 mini pigs were subjected to PVE, AE or assigned to the sham (SO) group. Correspondingly, 75% of the hepatic artery or portal vein branches were embolized. Growth and atrophy of the liver lobes, calculating the liver-to-body weight index (LBWI), laboratory data, arteriography, portography, Doppler ultrasound (US) and histopathology were analyzed. Results: After PVE, 2 animals had to be excluded due to technical problems. After AE, 4 animals had to be excluded because of technical problems and early sacrifice. Postprocedural US demonstrated effective AE and PVE of the respective lobes. Four weeks after PVE, portography showed a slow refilling of the embolized lobe by collateral portal venous vessels. Four weeks after AE, arteriography revealed a slight revascularization of the embolized lobes by arterial neovascularization. Segmental AE led to extensive necrotic and inflammatory alterations in the liver and bile duct parenchyma. Significant hypertrophy of the non-embolized lobe was only noted in the PVE group (LBWI: 0.91 ± 0.28%; p = 0.001). There was no increase in the non-embolized lobe in the AE (LBWI: 0.45 ± 0.087%) and SO group (LBWI: 0.45 ± 0.13%). Conclusion: PVE is safe and effective to induce segmental hypertrophy. Portal reperfusion by collateral vessels may limit hypertrophy. AE did not increase the segmental hepatic volume but carries the risk of extensive necrotic inflammatory damage.

Abstract
BACKGROUND Primary liver and biliary cancers are very aggressive tumors. Surgical treatment is the main option for cure or long term survival. The main purpose of this systematic review is to underline the indications for portal vein embolization (PVE), in patients with inadequate future liver remnant (FLR) and to analyze other parameters such as resection rate, morbidity, mortality, survival after PVE and hepatectomy for primary hepatobiliary tumors. Also the role of trans-arterial chemoembolization (TACE) before PVE, is investigated. METHODS A systematic search of the literature was performed in Pub Med and the Cochrane Library from 01.01.1990 to 30.09.2015. RESULTS Forty articles were selected, including 2144 patients with a median age of 61 years. The median excision rate was 90% for hepatocellular carcinomas (HCCs) and 86% for hilar cholangiocarcinomas (HCs). The main indications for PVE in patients with HCC and presence of liver fibrosis or cirrhosis was FLR <40% when liver function was good (ICGR15 < 10%) and FLR < 50% when liver function was affected (ICGR15:10-20%). The combination of TACE and PVE increased hypertrophy rate and was associated with better overall survival and disease free survival and should be considered in advanced HCC tumors with inadequate FLR. In patients with HCs PVE was performed, after preoperative biliary drainage, when FLR was <40%, in the majority of studies, with very good post-operative outcome. However indications should be refined. CONCLUSION PVE before major hepatectomy allows resection in a patient group with advanced primary hepato-biliary tumors and inadequate FLR, with good long term survival.

Abstract
In recent decades, there have been numerous advances in the management of liver cancer, cirrhosis, and diabetes mellitus. Although these diseases are wide ranging in their clinical manifestations, each can potentially be treated by exploiting the blood flow dynamics within the portal venous system, and in some cases, adding cellular therapies. To aid in the management of these disease states, minimally invasive transcatheter portal venous interventions have been developed to improve the safety of major hepatic resection, to reduce the untoward effects of sequelae from end-stage liver disease, and to minimize the requirement of exogenously administered insulin for patients with diabetes mellitus. This state of the art review therefore provides an overview of the most recent data and strategies for utilization of preoperative portal vein embolization, transjugular intrahepatic portosystemic shunt placement, balloon retrograde transvenous obliteration, and islet cell transplantation.

Abstract
The currently established standard for planning liver surgery is multistage contrast media-enhanced multidetector computed tomography (CM-CT), which as a rule enables an appropriate resection planning, e.g. a precise identification and localization of primary and secondary liver tumors as well as the anatomical relation to extrahepatic and/or intrahepatic vascular and biliary structures. Furthermore, CM-CT enables the measurement of tumor volume, total liver volume and residual liver volume after resection. Under the condition of normal liver function a residual liver volume of 25 % is nowadays considered sufficient and safe. Recent studies in patients with liver metastases of colorectal cancer showed a clear staging advantage of contrast media-enhanced magnetic resonance imaging (CM-MRI) versus CM-CT. In addition, most recent data showed that the use of liver-specific MRI contrast media further increases the sensitivity and specificity of detection of liver metastases. This imaging technology seems to lead closer to the ideal "one stop shopping" diagnostic tool in preoperative planning of liver resection.

Abstract
Colorectal cancer is a common malignancy and often presents with synchronous or metachronous distant spread. For patients with hepatic metastases, resection is the principal curative option. Liberalization of the indications for hepatic resection has introduced a number of challenges related to the size, distribution, and number of metastases as well as the condition of the future liver remnant. Advances in systemic therapy have solidified its role as both an important adjunct to surgery and also for many patients as a mechanism to facilitate resection. In patients whose disease is marginally resectable as a consequence of the distribution of hepatic lesions that precludes complete resection or out of concern for the future liver remnant, a number of strategies have been advocated, including prehepatectomy systemic therapy, staged surgical approaches, ablative technologies, and preoperative portal vein embolization. It is the purpose of this review to discuss ways in which to optimize the treatment of patients with potentially resectable disease, specifically those who are judged to have "borderline" resectable situations.

Abstract
BACKGROUND The optimal sequence for Gd-EOB-DTPA uptake measurement in the liver with the purpose of liver function measurement is still not defined. PURPOSE To prospectively evaluate the effect of an increased flip angle (FA) of a T1-weighted fat-saturated 3D sequence for the measurement of hepatocyte uptake of Gd-EOB-DTPA magnetic resonance imaging (MRI) after right portal vein embolization (PVE). MATERIAL AND METHODS Ten patients who received a PVE prior to an extended hemihepatectomy were examined 14 days after PVE using Gd-EOB-DTPA enhanced MRI of the liver using the standard FA of 10° and the increased FA of 30°. RESULTS Relative enhancement of the right liver lobe (RLL) was 0.52 ± 0.12 for 10° and 1.41 ± 0.39 for 30°. Relative enhancement of the left liver lobe (LLL) was 0.58 ± 0.11 for 10° and 2.05 ± 0.61 for 30°. Relative enhancement of the RLL was significantly higher for 30° than for 10° (P = 0.009) and significantly higher in the 30° than in the 10° sequences (P = 0.005) for the LLL. CONCLUSION A flip angle of 30° increases the contrast between liver partitions with and without portal venous embolization. Thereby, the sensitivity for differences in uptake intensity is increased. This could be of value for a more exact determination of differences in regional liver function and, consequently, the estimation of the future remnant liver function.

Abstract
PURPOSE To retrospectively analyze efficacy as measured by volume gain of future remnant liver (FRL) after right portal vein embolization (PVE) using particles only versus particles and additional central plug and/or coil (CP/C) embolization. METHODS All patients who underwent PVE between July 2011 and December 2012 were retrospectively analyzed. Right PVE was performed either with particle-only (PO) embolization or additional CP/C embolization. All enrolled patients underwent computed tomography or magnetic resonance imaging before PVE and surgery. The images were used for volumetry of the FRL. RESULTS Of 75 patients, 40 had PO and 35 CP/C embolization. Age, sex, and tumor entities did not differ significantly between the two groups. Tumor entities included cholangiocarcinoma (n = 52), metastasis from colorectal cancer (n = 14), hepatocellular carcinoma (n = 2), and others (n = 7). Time from PVE to preoperative imaging was similar in both groups. FRL volume before PVE was 329 ± 121 ml in the PO group and 333 ± 135 ml in the CP/C group, and 419 ± 135 ml and 492 ± 165 ml before operation. The average percentage volume gain was significantly higher in the CP/C group than in the PO group, with 53.3 ± 34.5 % versus 30.9 ± 28.8 % (p = 0.002). CONCLUSION Right PVE with additional CP/C embolization leads to a significantly higher gain in FRL volume than embolization with particles alone.

Abstract
BACKGROUND Portal vein embolization not only induces hypertrophy of the non-embolized liver, but also enhances tumor growth. The latter could be prevented by embolizing the hepatic arteries supplying the tumor-bearing liver segments. This study aimed to determine the effects of transcatheter arterial embolization (TAE) on tumor volume and liver regeneration in a rabbit VX2 tumor model. METHODS Twenty-three rabbits underwent subcapsular tumor implantation with a VX2 tumor. Two weeks after implantation, 18 rabbits were used for TAE experiments, 5 were for sham controls. Tumor response and liver regeneration response of the embolized cranial and non-embolized caudal liver lobes were assessed by CT volumetry, liver to body weight index, and the amount of proliferating hepatocytes. RESULTS All super-selective arterial tumor embolization procedures were performed successfully. Despite embolization, the tumor volume increased after an initial steady state. The tumor volume after embolization was smaller than that of the sham group, but this difference was not significant. Massive necrosis of the tumor, however, was seen after embolization, without damage of the surrounding liver parenchyma. There was a significant atrophy response of the tumor bearing cranial lobe after super-selective arterial embolization of the tumor with a concomitant hypertrophy response of the non-embolized, caudal lobe. This regeneration response was confirmed histologically by a significantly higher number of proliferating hepatocytes on the Ki-67 stained slides. CONCLUSIONS Super-selective, bland arterial coil embolization causes massive necrosis of the tumor, despite increase of volume on CT scan. Atrophy of the tumor bearing liver lobe is seen after arterial embolization of the tumor with a concomitant hypertrophy response of the non-embolized lobe, despite absence of histological damage of the tumor-surrounding liver parenchyma.

Increase in left liver lobe function after preoperative right portal vein embolisation assessed with gadolinium-EOB-DTPA MRI. Eur Radiol 2013; 23:2555-60.

Abstract
OBJECTIVES To prospectively evaluate the early development of regional liver function after right portal vein embolisation (PVE) with Gd-EOB-DTPA-enhanced MRI in patients scheduled for extended right hemihepatectomy. METHODS Ten patients who received a PVE before an extended hemihepatectomy were examined before and 14 days after PVE using Gd-EOB-DTPA-enhanced MRI of the liver. In these sequences representative region of interest measurements were performed in the embolised right (RLL) and the non-embolised left liver lobe (LLL). The volume as well as hepatic uptake index (HUI) was calculated independently for each lobe. RESULTS Relative enhancement 14 days after PVE decreased in the RLL and increased significantly in the LLL (P < 0.05). Average hepatic uptake index (HUI) for RLL was significantly lower 14 days after PVE than before PVE (P < 0.05) and significantly higher for LLL (P < 0.05). CONCLUSIONS A significant shift of contrast uptake from the right to the left liver lobe can be depicted as early as 14 days after right PVE by using Gd-EOB-DTPA-enhanced MRI, which could reflect the redirected portal venous blood flow and the rapid utilisation of a hepatic functional reserve. KEY POINTS • Preoperative portal vein embolisation (PVE) is widely performed before right-sided hepatic resection. • PVE increases intravenous contrast medium uptake in the left lobe of liver. • The hepatic uptake index for the left liver lobe increases rapidly after PVE. • Left liver lobe function increase may be visualised by Gd-EOB-DTPA-enhanced MRI.

Abstract
Portal vein embolization (PVE) is an established therapy used to redirect portal blood flow away from the tumor-bearing liver to the anticipated future liver remnant (FLR) and usually results in FLR hypertrophy. PVE is indicated when the FLR is considered too small before surgery to support essential function after surgery. When appropriately applied, PVE reduces postoperative morbidity and increases the number of patients eligible for curative hepatic resection. PVE also has been combined with other therapies to improve patient outcomes. This article assesses more recent outcomes data regarding PVE, reviews the existing controversies, and reports on novel strategies currently being investigated.

Abstract
Curative treatment of Klatskin tumors by radical surgical procedures with surgical preparation distant to the tumor region results in 5-year survival rates of 30-50%. This requires mandatory en bloc liver resection and resection of the extrahepatic bile duct often together with vascular resection. Nevertheless, the ideal safety margin of 0.5-1 cm remote from the macroscopic tumor extensions cannot be achieved in all cases. Based on hilar anatomy the probability of an adequate safety margin is higher using extended right hemihepatectomy together with portal vein resection compared to left hemihepatectomy. However, due to severe atrophy of the left liver lobe solely left-sided hepatectomy is feasible in some patients. In cases of eligibility for both procedures right hemihepatectomy is preferentially used due to the higher oncological radicality if sufficient liver function is present. Postoperative hepatic insufficiency and bile leakage after demanding biliary reconstruction, often with several small orifices, contribute to the postoperative complication rate of this complex surgical disease pattern.

Abstract
PURPOSE Alternative methods to optimize the hypertrophy response after portal vein embolization (PVE) are desired. This study assessed the effect of hepatic vein embolization (HVE) in addition to PVE on liver hypertrophy response in a standardized rabbit model. MATERIALS AND METHODS Thirty rabbits were allocated to groups according to intervention: PVE alone, HVE alone, and a combination of HVE and PVE. The liver regeneration response of the nonembolized, caudal liver was assessed by computed tomographic volumetry, liver-to-body weight index, and the amount of proliferating hepatocytes. RESULTS The caudal liver volume (CLV) increased significantly more in the PVE and combined PVE/HVE group than in the HVE group at 3 and 7 days after the procedure (P < .01). There were no significant differences in CLV increase or degree of hypertrophy between the PVE and combined embolization groups. The caudal liver-to-body weight index was significantly higher in the PVE and combined embolization groups than in the HVE group on day 7 (P < .01). The index was also significantly higher in the combined PVE/HVE group compared with the PVE group (P = .008). The caudal liver tissue of the PVE and combined groups contained a significantly higher number of proliferating hepatocytes compared with the HVE group on day 7 (P < .01). CONCLUSIONS Although histologic and additional regenerative changes are seen, HVE in addition to PVE has no additional short-term effect on hypertrophy response. The combination of HVE and PVE may therefore have little use in a clinical setting.
