# Endovascular management of KILT syndrome and COVID-19-related extensive deep vein thrombosis in a pregnant patient: A case report

## TL;DR

A pregnant woman with KILT syndrome and severe blood clots due to COVID-19 was treated with endovascular techniques, showing potential benefits of this approach.

## Contribution

Demonstrates the use of endovascular thromboaspiration/thrombolysis and IVC filter placement in managing KILT syndrome-related thrombosis.

## Key findings

- Endovascular treatment successfully recanalized the inferior vena cava in a pregnant patient with KILT syndrome.
- Thrombotic restenosis occurred at the filter level, necessitating its removal during follow-up.
- The case suggests endovascular techniques may be effective in acute thrombotic events related to KILT syndrome.

## Abstract

We report on a 20-year-old pregnant woman who tested positive for SARS-CoV-2 and was diagnosed with KILT syndrome, a rare condition that increases the risk of thrombotic events. The patient showed signs of deep vein thrombosis that extended from the bilateral iliac vein to the inferior vena cava (IVC), which was treated with placement of an IVC filter and endovascular thromboaspiration/thrombolysis. The IVC was successfully recanalized; however, during follow-up, thrombotic restenosis occurred at the filter level, requiring filter removal. This case highlights the potential benefits of endovascular thromboaspiration/thrombolysis and IVC filter placement in patients with KILT syndrome presenting with acute thrombotic events.
