Supraumbilical Skin Rash and Fat Necrosis after Transcatheter Arterial Chemoembolization: A Case Report

99m Tc-Macroaggregated Albumin Liver Lung Shunt Study With Uptake Indicative of Patent Falciform Artery

ABSTRACT

Intra-arterial injection of radioactive isotope 90-yttrium 90 Y has been used for elective internal radiation therapy for the treatment of localized hepatocellular carcinoma deemed surgically unresectable. It has also been used to treat intrahepatic cholangiocarcinoma and colorectal cancer that has metastasized to the liver. To prepare for 90 Y treatment, preprocedural mapping via hepatic angiography and 99m Tc-macroaggregated albumin liver lung shunt study followed by postprocedural 90 Y SPECT/CT is essential to ensure a targeted therapy. Therapy is contraindicated if lung shunt fraction is greater than 20% for SIR-Spheres. Anatomic variation in hepatic angiography may be present that can lead to complications if unaccounted for.

Rash and subcutaneous fat necrosis after DEB-TACE with doxorubicin

A 73-year-old woman with hepatocellular carcinoma localised to the liver was treated with doxorubicin-loaded drug-eluting beads through transcatheter arterial chemoembolisation (DEB-TACE). She developed subcutaneous, erythematous, tender nodules in her abdomen 3 days after the procedure. PET/CT scan that was done to evaluate for evidence of disease progression showed mild avidity of these nodules. Biopsy showed fatty necrosis. Nodules started to improve spontaneously 2 weeks after onset. At 8 weeks after onset, lesions stabilised in size and the associated tenderness and erythema resolved. This represents a rare side effect of TACE procedure in general. It can happen secondary to non-target embolisation of hepatic falciform artery, planned embolisation of extrahepatic collateral supplies and even when there is no clear cause. Spontaneous resolution of acute symptoms usually occurs over the course of few weeks, though subcutaneous lesions consisting of necrotic fat tissue may persist for longer periods.

Arteries of the falciform ligament on C-arm CT hepatic arteriography: The hepatic falciform artery and the Sappey's superior artery

BACKGROUND AND AIM

To investigate the prevalence, anatomy and distribution of the hepatic falciform artery (HFA) and Sappey's superior artery (SSA) using C-arm CT hepatic arteriography (C-arm CTHA).

MATERIALS AND METHODS

From January 2011 to December 2012, 220 patients who underwent C-arm CTHA during initial transarterial treatment for hepatocellular carcinoma were included in this retrospective study. The HFAs and SSAs prevalence and origin were evaluated using axial images of C-arm CTHA. A 5-point scale for HFAs and a 4-point scale for SSAs were used to designate the radiologically conspicuous arteries.

RESULTS

The prevalences of the total HFAs and SSAs were 95 % (n=209) and 22 % (n=49), while those of radiologically conspicuous HFAs and SSAs were 62 % (n=137) and 10 % (n=22), respectively. Thirty HFAs (22 % of radiologically conspicuous HFAs and 14 % of the total study population) were distributed in the subcutaneous layer of the anterior abdominal wall, while the majority of SSAs ran through the superior part of the falciform ligament in the left-anterior direction and anastomosed with left inferior phrenic artery.

CONCLUSION

Our study using C-arm CTHA revealed that the prevalence of the HFA is higher than the existing knowledge and proved the existence of the SSA radiologically for the first time.

KEY POINTS

• Prevalence of hepatic falciform artery is 95 %, higher than previously known. • 22 % of conspicious hepatic falciform arteries distributed in subcutaneous tissue around umbilicus. • The existence of Sappey's superior artery was proved with a radiological method.

Abdominal Skin Rash After TACE Due to Non-Target Embolization of Hepatic Falciform Artery

Transcatheter arterial chemoembolization (TACE) is a well-recognized procedure for management of hepatocellular carcinoma. We present a 54-year-old man who presented with a periumbilical maculopapular skin rash that developed after an otherwise uneventful TACE procedure. A retrospective review of imaging was consistent with non-target embolization of the hepatic falciform artery (HFA). He was treated with oral non-steroidal antiinflammatory medication for 3 weeks with improvement, but had slight skin induration and an excoriated papule at 6-month follow-up. Non-target embolization of HFA is very rare, but clinicians and interventionalists should be aware of this complication, especially in patients predisposed to enlargement of HFA.

Skin Necrosis Resulting from Nontarget Embolization of the Falciform Artery during Transarterial Chemoembolization with Drug-Eluting Beads

Intra-arterial embolic therapies are a mainstay of liver-directed therapies to palliate symptoms, improve survival, and bridge patients to transplantation. Vascular anatomy and type of embolic used can lead to complications of nontarget embolization with varying clinical consequences. This case report describes a rare, nontarget embolization of the falciform artery leading to supraumbilical skin necrosis.

A case of hepatocellular carcinoma with skin injury of the upper abdominal wall after transcatheter arterial chemoembolization: a case report

INTRODUCTION

Transcatheter arterial chemoembolization has been widely used to treat advanced hepatocellular carcinoma that cannot be treated by local ablation therapies or surgical resection. The effectiveness of transcatheter arterial chemoembolization in prolonging survival has been well established, and approximately one third of newly discovered hepatocellular carcinoma patients were repeatedly treated by transcatheter arterial chemoembolization in Japan. Various kinds of complications have been reported, and many of which are general complications such as hepatic coma, jaundice, fever-up, ascites, and bile duct injury. The hepatic falciform artery is found frequently during postmortem anatomic dissection and the incidence of hepatic falciform artery is reported to be over 60%. Hepatic falciform artery is known to be the responsible artery for supraumbilical skin rash development after arterial chemo infusion therapy; however, skin complications after transcatheter arterial chemoembolization are rare.

CASE PRESENTATION

A 70-year-old female with chronic hepatitis C infection was diagnosed as having hepatocellular carcinoma (S4, 20 mm in diameter). Transcatheter arterial chemoembolization was performed via the left hepatic artery, which was a feeding artery of the hepatocellular carcinoma. Two days after that, supraumbilical skin rash with local tenderness and redness appeared. Retrospective analysis revealed that occlusion of the hepatic falciform artery branching from the left hepatic artery with micromaterials caused the skin lesion.

CONCLUSION

We should keep in mind that anticancer drugs or embolic materials can flow into the HFA and may cause abdominal wall injury after transcatheter arterial chemoembolization.
