RESUMEN
Chronic limb-threatening ischemia (CLTI) is an important issue for elderly patients with peripheral artery disease. Here, we present the case of a 91-year-old man with CLTI, residing in a rural district. The onset of CLTI rapidly deprived him of ambulation because of a foot infection. Given that he had difficulty with long-distance transportation, limb salvage for extensive tissue loss was performed at a district facility, based on his and his family's request. Finally, skin grafting on the cutting plane of the right ankle bones resulted in wound healing in six months after incomplete revascularization and multiple minor amputations.
RESUMEN
Post-traumatic arteriovenous fistula (AVF) is a vascular injury complication and can present with vessel dilation, forming pulsatile varices, venous hypertension, distal ischemia, and congestive heart failure. We present a case of only pulsatile mass and leg pain caused by a 60-year-old post-traumatic AVF. Computed tomography angiography showed an AVF between the superficial femoral artery and superficial femoral vein. Surgical repair with AVF ligation was successfully performed. Traumatic AVF caused vascular and heart failure in the future; therefore, post-traumatic AVF is better eliminated as soon as possible.
RESUMEN
Neurofibromatosis type 1 (NF-1) is associated with fatal vascular complications. A 40-year-old woman with NF-1 who had previously undergone left iliac artery ligation and femorofemoral bypass grafting for internal iliac artery (IIA) aneurysm rupture was transported to our hospital for the treatment of a newly developed IIA aneurysm. Although endovascular therapy was difficult owing to the previous surgery, we successfully performed embolization of the aneurysm and its feeding vessels via direct percutaneous puncture under ultrasound guidance. Aneurysm enhancement had completely disappeared at 2 months postoperatively. We have reported a novel approach of direct percutaneous puncture for IIA aneurysm embolization in a patient with NF-1.
