Embolia cerebral como presentación atípica de síndrome de May Thurner

El síndrome de May-Thurner es una anormalidad anatómica que consiste en la comprensión cronica de la vena iliaca común izquierda, entre la arteria ilíaca común derecha y la columna vertebral, que puede predisponer a la trombosis venosa profunda. Es una entidad rara, y es infrecuente que provoque una embolia paradojal cerebral. Se presenta el caso de una isquemia cerebral de origen embólico, en un varón de 30 años, luego de actividad sexual. Los estudios realizados revelaron síndrome de May-Thurner asociado con un foramen oval permeable y una trombofilia por factor V de Leiden. Fue tratado con anticoagulantes orales y no ha presentado recurrencias.

May-Thurner syndrome is an anatomic abnormality that predisposes patients to increase risk of paradoxical embolism and stroke. It consists of chronic compression of the left common iliac vein by the overlying right common iliac artery and lumbar spine. This may lead to deep venous thrombosis and paradoxical embolism that could provoke cerebral ischemia in patients with a cardiac shunt from right-to-left. Embolic cerebral ischemic event is reported in a 30-year-old man after sexual intercourse. Further studies revea led suggestive findings of May-Thurner syndrome coupled with a patent foramen ovale and a factor V Leiden thrombophilia. He was placed on anticoagulation therapy and has not had any recurrent events.

Presentación atípica de síndrome infrecuente: absceso como inicio de síndrome de May-Thurner / Atypical presentation in an uncommon syndrome: abscess as debut of May-Thurner syndrome

Resumen Objetivo Presentar un caso de inicio atípico de síndrome de May-Thurner, enfermedad vascular poco frecuente. Caso clínico Se reporta el caso de una paciente de 23 años con absceso de pie izquierdo y extenso edema de dicha extremidad. El dímero D y la ecotomografía doppler color venosa descartan evento trombótico agudo. El estudio complementario con angioTC objetiva compresión del origen de la vena ilíaca común izquierda, presencia de venas colaterales y diferente grado de insuficiencia venosa en dicha extremidad, hallazgos compatibles con el síndrome de May-Thurner. Conclusión El síndrome de May-Thurner representa una causa inusual y de presentación variable en enfermedad venosa de extremidad inferior izquierda en mujeres jóvenes.

ABSTRACT Aim To present a case of an atypical debut of May-Thurner syndrome, uncommon vascular disease. Case report We report a case of a 23 year old female with an abscess of the left foot and extensive edema of the left lower limb. D-Dimmer test and Venous Doppler ultrasound discards an acute trombotic event. Further studies with CT angiogram concludes the compression in the origin of the left common iliac vein compatible with May-Thurner syndrome. Conclusion May-Thurner syndrome represent an uncommon and variable cause of venous disease of the left lower limb in young female patients.

Síndrome de May Thurner con accidente cerebrovascular isquémico y foramen oval permeable / May Thurner syndrome with ischemic cerebrovascular accident and permeable oval foramen

La asociación de accidente cerebral isquémico con foramen oval permeable, no ha sido extensamente estudiada, y frecuentemente el sitio de origen de la embolia no se detecta a pesar de los estudios de rutina. Se presenta el caso de un paciente joven con accidente cerebral vascular isquémico y foramen oval permeable en el contexto de síndrome de May Thurner. El síndrome de May Thurner es una entidad poco estudiada en la literatura médica y además se lo ha relacionado poco con accidente cerebral vascular isquémico, pero en pacientes con foramen oval permeable sin evidencia de la fuente embolígena, es interesante descartarlo como causa de embolia paradojal.

The association of cerebral ischemic attack with patent foramen ovale has not been extensively studied, and frequently the site of origin of embolism is not detected despite routine studies. We present the case of a young patient with ischemic stroke and permeable oval foramen in the context of May Thurner syndrome. The May Thurner syndrome is an entity scarcely studied in the medical literature and it has also been infrequently related to ischemic vascular cerebral accident, but in patients with permeable oval foramen without evidence of the emboligen source, it is interesting to rule it out as a cause of paradoxical embolism.

Pyoderma gangrenosum associated with left iliac vein compression syndrome: presentation of difficult diagnosis

Abstract: Pyoderma gangrenosum is a rare neutrophilic dermatosis of unknown etiology, of which the most frequent clinical manifestations are ulcers. The diagnosis difficulty is, among other things, to rule out other causes of ulcers, since it is considered a diagnosis of exclusion. Skin ulcerations may also occur in the iliac vein compression syndrome, which, like pyoderma gangrenosum, mainly affects young women. Because they have such similar characteristics, the presence of vascular disease may hinder the diagnosis of concurrent pyoderma gangrenosum. Because of the clinical relevance of ulcerated lesions and scars, the early diagnosis and treatment of this condition is considered extremely important. We report a case in which the two diseases were associated, hampering the diagnosis of pyoderma gangrenosum.
