Large artery occlusive disease

Arterite de Takayasu e gravidez

A arterite de Takayasu é uma doença inflamatória crônica, idiopática que afeta a grandes vasos como a aorta e seus principais ramos. Esta doença é uma causa rara de hipertensão em mulheres em idade fértil. Este artigo discute a abordagem clínica multidisciplinar necessária ao acompanhamento de gestantes com esta síndrome.

Cross-sectional pattern of collateral vessels in patients with superficial femoral artery occlusion

RATIONALE AND OBJECTIVES

The purpose of this study was to identify the cross-sectional location of collateral vessels in patients with peripheral vascular disease on three-dimensional magnetic resonance angiograms (3D MRAs) to suggest sites for intravascular or transcutaneous angiogenesis gene delivery in the lower extremity.

METHODS

The axial locations were measured and categorized by tissue compartments, as well as by radial coordinates with respect to the femur.

RESULTS

Collateral vessels in the thigh were identified in 24 of 93 consecutive patients who underwent peripheral 3D MRA. Ninety-one percent (99/109) of the observed collaterals were located near the adductor canal level of the thigh, with 78% (31/46) of these collaterals located in the fat in or surrounding the posterior muscle.

CONCLUSIONS

The majority of collateral vessels in the thigh are located in the fat or muscle within the posterior compartment near the femur at the level of the adductor canal.
