A persistent sciatic artery is a rare congenital vascular anomaly. The most common complication is aneurysm. Clinical presentation may include symptoms resulting from arterial dilatation and ischemia caused by thrombosis or embolization. There are diverse options for treatment of this rare condition, ranging from ligature of the aneurism to endovascular repair. This report describes the case of a female patient complaining of a pulsating mass in the left buttock. She was referred to a Vascular Service where an angiotomography showed complete bilateral persistence of the sciatic artery, with an aneurysm of the left sciatic artery. The aneurysm was treated with endovascular techniques, via a contralateral approach, with placement of two stent grafts and preservation of distal patency. Patency is particularly important in cases of this anatomical variation in which the persistent sciatic artery is complete. This patient recovered well.

Introduction: The persistent sciatic artery (PSA) is a rare congenital vascular anomaly that arises when the embryonic axial artery fails to regress, potentially leading to serious complications such as limb ischemia.
Case Presentation: We report the case of a 47-year-old woman with a history of essential hypertension and recent hormonal treatment for uterine fibroids. She developed acute limb ischemia due to bilateral PSA thrombosis, which was confirmed through comprehensive imaging.

Unlabelled: Persistent sciatic artery (PSA) is a rare congenital anomaly that may involve aneurysmal formations. During endovascular treatment for PSA aneurysm (PSAA) occlusion, guidewire crossing can be challenging due to complex anatomy. We report successful endovascular intervention for PSAA occlusion using the "direct tip injection in occlusive lesions (DIOL)" fashion, in which hydraulic pressure with contrast facilitates guidewire crossing by visualizing the vessel course and expanding the microchannel and vessel lumen.

Numerous conduits have been developed to improve peripheral nerve regeneration. However, challenges remain, including remote control of conduit function, and programmed cell behaviors like orientation. We synthesized FeO-MnO@Zirconium-based Metal-organic frameworks@Retinoic acid (FMZMR) core-shell and assessed their impact on Schwann cell function and behavior within conduits made from decellularized human umbilical arteries (DHUCA) under magnetic field (MF).

Diabetic peripheral neuropathy (DPN) is a common complication of diabetes, often accompanied by impaired vascular endothelial function in the lower limbs. This dysfunction is characterized by a reduced vasodilatory response, leading to decreased blood flow in the lower limbs and ultimately contributing to the development of diabetic peripheral neuropathy. To delve deeper into this pathological process, the study employed bioinformatics to identify and analyze genes highly active in DPN.
