Super Selective Embolization and Immediate Resection of a High-flow Arteriovenous Malformation in the Hand.

A significant proportion of high-flow arteriovenous malformations (AVMs) in the hand are complex to treat due to their multicentricity, size, and risk of jeopardizing distal circulation. Therefore, AVMs are frequently considered "inoperable." We present the case of a multifocal recurrent AVM treated in conjunction with the interventional radiology department, with intra-arterial embolization and excision followed by immediate distal revascularization to replace the resulting arterial deficit.

Reversed priapism, thrombosis of the dorsal penile vein: A case report.

Priapism is an unintentional prolonged penile erection, lasting equal to or greater than 4 hours, in the absence of sexual stimulation or after having finished it. It is a rare pathology that can represent a urological emergency. The present report describes the case of a 25-year-old patient who presented priapism after suffering a one-meter fall on the genital area.

Carotid paragangliomas. Alternatives for presurgical endovascular management.

Carotid paragangliomas (CP) are rare tumors, representing 0.6% of the head and neck tumors. These tumors have their origin in the carotid body located in the adventitia of the vascular wall of the carotid bifurcation.

In Situ Pulmonary Thrombolysis and Perfusion Lung Angiography in Severe COVID-19 Respiratory Failure.

Unlabelled: A proof-of-concept study using thrombolysis with catheter-directed tissue plasminogen activator (tPA) and pulmonary angiography imaging was performed to visualize perfusion deficits and reperfusion/therapeutic effects of tPA.

Design: A prospective, open-label, compassionate study. Descriptive statistics were presented for categorical variables and as means with sds for continuous variables.

Scrotal arteriovenous malformation: Case report.

Scrotal arteriovenous malformations (AVM) are extremely rare, making them difficult and complex to diagnose, and a therapeutic challenge; few cases of this type have been reported in the literature. This article reports the case of a male patient, 12 years old, with congenital AVM and background of treatment with sclerotherapy and embolization: it was decided to perform a surgical resection, which was successful. Angiography is obligatory in arteriolar cases, and it was backed up with surgical AVM treatment, taking into account the great importance of pre-surgical embolization.

May-Thurner syndrome with inferior mesenteric vein drainage and porta system - Case report.

We present the case of a 12-year-old girl with a history of vascular anomalies in the lower pelvic limbs and back, who developed unilateral deep vein thrombosis of the left lower limb after her pubertal development, she was diagnosed with May-Thurner syndrome with an abnormal venous drainage of the pelvic structures through the superior hemorrhoidal veins to the inferior mesenteric vein towards the porta system, this being a chronic manifestation. This kind of behavior has not been documented in the reviewed medical literature. Secondarily, balloon angioplasty was performed without breaking the stenotic ring.
