# Pseudoaneurysm formation after embolization of giant arteriovenous malformation of the lower limb associated with Parkes Weber syndrome: A case report and literature review

## TL;DR

A woman with Parkes Weber syndrome faced complications after treatment for a large blood vessel malformation in her leg, highlighting the challenges in managing this condition.

## Contribution

This case report adds to the literature by detailing a rare complication and long-term management challenges in Parkes Weber syndrome.

## Key findings

- A 63-year-old woman with Parkes Weber syndrome developed a pseudoaneurysm after embolization of a giant AVM.
- Re-embolization initially reduced the pseudoaneurysm, but it expanded again and led to a fatal outcome.
- Review of 15 cases emphasizes the complex and prolonged treatment journey for PWS-associated AVMs.

## Abstract

A 63-year-old woman presented with a giant arteriovenous malformation (AVM) of the lower limbs associated with Parkes Weber syndrome (PWS). The AVM was supplied by 4 branches of the right profunda femoris artery and 4-stage embolization was performed. At 67 years of age, she developed a pseudoaneurysm due to the recanalization of a coiled profunda femoris artery branch arterial aneurysm. We performed re-embolization of the coiled profunda femoris artery and observed its shrinkage, but 2 months later, the pseudoaneurysm began to expand again, having a fatal course. This case indicates that battles against giant AVM-associated PWS follow a long and convoluted path. We present this case with reviewing 15 previously reported cases to improve our management of PWS.
