Guidelines for management of actual or suspected inadvertent intra-arterial injection of sclerosants.

Background: Inadvertent intra-arterial injection of sclerosants is an uncommon adverse event of both ultrasound-guided and direct vision sclerotherapy. This complication can result in significant tissue or limb loss and significant long-term morbidity.

Objectives: To provide recommendations for diagnosis and immediate management of an unintentional intra-arterial injection of sclerosing agents.

Cerebrospinal venous obstruction and breast cancer: A pilot study.

Methods: The venous drainage of the breasts is described and the cerebrospinal venous systems (CSVS) of six patients with treated breast cancer were assessed using duplex ultrasound to measure venous blood volume flows in the neck veins.

Results: All six patients with breast cancer showed evidence of cerebrospinal venous obstruction (CSVO). Further, all six demonstrated collateral flow in the erect position in the internal jugular vein on the same side as the diagnosed breast cancer.

Sclerotherapy of lower limb veins: Indications, contraindications and treatment strategies to prevent complications - A consensus document of the International Union of Phlebology-2023.

Background: Sclerotherapy is a non-invasive procedure commonly used to treat superficial venous disease, vascular malformations and other ectatic vascular lesions. While extremely rare, sclerotherapy may be complicated by serious adverse events.

Objectives: To categorise contraindications to sclerotherapy based on the available scientific evidence.
