Spinal cord injury after conducting transcatheter arterial chemoembolization for costal metastasis of hepatocellular carcinoma

Spinal cord ischemia after transcatheter artery chemoembolization for hepatocellular carcinoma: A case-report

INTRODUCTION

Transarterial hepatic chemoembolization (TACE) has been used to treat unresectable hepatocellular carcinoma and has gained widespread acceptance as a treatment for both primary and secondary hepatic malignancies.

CASE REPORT

We report a case of 78-year-old male patient with chronic hepatitis B, diagnosed with HCC. He underwent the second TACE, and right after the procedure, the patient abruptly developed bilateral lower extremities motor weakness and sensory impairment below the T10 dermatome. Spinal magnetic resonance imaging showed T2-weighted scans showed increased intramedullary signal strength at the T1-T12 level. The patient received supportive care, ongoing rehabilitation, and steroid pulse therapy. The motor strength remained unchanged, but the sensory deficiencies practically disappeared.

CLINICAL DISCUSSION

The hepatic artery injury or decreased flow at the prior TACE site, which causes collateral recruitment, can explain why spinal cord injury following TACE typically happens after the second or third session. It can occasionally result from accidental embolized spinal branches originating from intercostal or lumbar collateral arteries. In our case, we hypothesize the embolism caused the infarction to the spinal cord travel through the connection between the lateral branches of the right inferior phrenic artery and the intercostal arteries, which supply the spinal cord through the anterior spinal artery.

CONCLUSIONS

TACE in rare case can have severe complications. A tailored therapeutic strategy, including consideration of a shunt and selection of the vessels utilized for the Lipiodol infusion prior to TACE, is crucial to achieving an optimal end outcome to avert these significant consequences.

Paraplegia following transarterial chemoembolisation for hepatocellular carcinoma: a case report

BACKGROUND

Transarterial chemoembolisation (TACE) is considered standard treatment for intermediate-stage hepatocellular carcinoma (HCC). Although TACE is viewed as a safe and effective procedure, it may still present with various complications, including spinal cord injury, though very rarely.

METHODS

A 74-year-old male was diagnosed with non-B, non-C HCC, segment 4, cT2N0M0, AJCC stage II, BCLC stage B. Angiography had shown a hypervascular tumour stain indicating that both T10 and T11 were tumour-feeding arteries, TACE then performed. After TACE, loss of sensation and motor functions involving the trunk below the umbilicus and both lower extremities were noted. The patient immediately underwent steroid pulse therapy. However, 100 days after TACE, the symptoms showed no improvement.

DISCUSSION

Because of anatomy and neurological distribution, it is conceivable that the embolic materials originating from the TACE procedure might have led to an embolic event with a serious manifestation, although the blood supply of the spinal cord encompasses multiple anastomoses.

CONCLUSION

Spinal cord injury is an extremely rare but grave complication of TACE. Paraplegia may result from inadvertent embolisation of spinal branches arising from intercostal or lumbar collateral vessels. This case highlights the necessity of evaluating and choosing the vessels before starting TACE to achieve a good outcome.

Paraplegia after transcatheter artery chemoembolization in a child with clear cell sarcoma of the kidney: A case report

BACKGROUND

Transcatheter arterial chemoembolization (TACE) is a common treatment for inoperable malignant renal tumors. However, a series of complications may follow the TACE treatment. Spinal cord injury caused by the embolization of intercostal or lumbar arteries is extremely rare.

CASE SUMMARY

We describe a case with quite uncommon spinal cord injury after TACE in a 3-year-old child with clear cell sarcoma of the kidney. Sensory impairment beneath the T10 dermatomes and paraplegia on the day after TACE were found in this patient. Unfortunately, sustained paraplegia still existed for more than 2 mo after TACE despite the large dose of steroids and supportive therapy.

CONCLUSION

We should draw attention to an uncommon complication of paraplegia after TACE treatment in malignant renal tumors. Although it is rare, the result is disastrous.

Selective Versus Non-selective Transarterial Chemoembolization via the Intercostal Artery for the Treatment of Hepatocellular Carcinoma

PURPOSE

To report the 1-month tumor response and safety of selective transarterial chemoembolization (TACE) via the intercostal artery (ICA) for the treatment of hepatocellular carcinoma (HCC) in comparison with those of non-selective TACE.

METHODS

This retrospective study included 79 HCC patients who underwent TACE via the ICA selectively (selective TACE group; n = 26) or non-selectively (non-selective TACE group; n = 53) between January 2001 and December 2016. Selective TACE was defined when TACE was performed with selective catheterization of the tumor feeding branch of the ICA. TACE performed without selective catheterization of the tumor feeding branch was defined as non-selective TACE. One-month target and overall tumor responses and complications of the two groups were compared. Univariate and multivariate analyses were performed to identify prognostic factors.

RESULTS

Selective TACE group showed better 1-month target and overall tumor responses and lower frequency of complications than non-selective TACE group (P = .007, P = .018, and P < .001, respectively). Performing selective TACE was the only significant favorable factor for better target and overall tumor responses (P = .001 and P = .028, respectively). In univariate analysis for complications, serum α-fetoprotein > 200 ng/mL and non-selective TACE were statistically significant. However, multivariate analysis showed that performing non-selective TACE was the only significant risk factor (odds ratio 13.56; 95% confidence interval 3.51-52.5; P < .001).

CONCLUSION

Compared to non-selective TACE via the ICA, selective TACE via the ICA for the treatment of HCC can achieve better tumor response and safety.

Management of visceral artery embolization using 0.010-inch detachable microcoils

Transcatheter coil embolization is used primarily to treat arterial hemorrhages, tumors, aneurysms, and vascular malformations. However, conventional microcatheter systems cannot always be employed in difficult cases. In this technical note, we describe how small-diameter primary coils and microcatheter tips that are thinner than normal can be used to increase the safety and reliability of coil embolization.

Spinal cord ischemia secondary to transcatheter arterial chemoembolization for hepatocellular carcinoma

Transcatheter arterial chemoembolization (TACE) is accepted worldwide as an effective treatment for patients with unresectable hepatocellular carcinoma. Although considered relatively safe, TACE has been associated with several complications. Spinal cord ischemia secondary to TACE is an extremely rare but disastrous complication. We report a very rare case of spinal cord injuries after TACE, together with a literature review. During the procedure, the patient suddenly experienced sensory impairment below the T10 dermatome and bilateral lower extremity motor weakness. She was given high-dose steroids and supportive therapy. The sensory deficits nearly improved completely, but motor strength remained unchanged. Thereafter, a chest computed tomography scan showed tumor metastasis to the lungs. The patient is now receiving sorafenib and follow-up.
