RESUMEN
A 74-year-old man with diabetes and end-stage renal failure on regular dialysis required revascularization for gangrene of multiple toes and a heel ulcer on the right foot with chronic limb-threatening ischemia. However, the anterior tibial artery, posterior tibial artery, and peroneal artery, which are the usual targets below the knee, showed obstruction or calcification and were considered inappropriate bypass targets. Instead, a collateral artery developed along the area of the posterior tibial artery, and bypass surgery was performed with this artery. This is a case report showing successful collateral artery bypass grafting in the distal infrapopliteal segment.
RESUMEN
Immunoglobulin G4-related disease (IgG4-RD) can affect various organs, including the cardiovascular system. In this study, we described the case of a 72-year-old man with periaortitis both in the ascending and terminal aorta related to IgG4-RD. He presented with swelling in the left leg. Computed tomography (CT) showed increased wall thickness of the ascending aorta and retroperitoneal fibrosis, which, in turn, caused deep vein thrombosis. Using positron emission tomography-computed tomography, the patient was diagnosed with IgG4-RD in the aorta. Although it was difficult to distinguish intramural hematoma (IMH) from IgG4-related periaortitis, treatment with steroids has dramatically improved his periaortitis. IgG4-related periaortitis should be differentiated from IMH due to their similar morphologies.
RESUMEN
Ischemic limbs with infected heel ulcers are often difficult to salvage. We present a case of an 82-year-old woman who had bilateral heel ulcers owing to chronic limb-threatening ischemia. She underwent right femoral-terminal posterior tibial artery bypass surgery, but right calcaneus osteomyelitis occurred and inhibited wound healing. She underwent partial calcanectomy (PC), and her right heel healed six months after the bypass surgery. The ulcer on her left foot also healed after distal bypass and PC. We describe our experience with a patient who needed PC to cure her heel ulcers.
RESUMEN
A 51-year-old man with severe comorbidities required redo revascularization due to left chronic limb-threatening ischemia caused by a previous vein graft occlusion. The saphenous veins were not available due to previous surgeries. Femoro-posterior tibial artery bypass surgery was successfully performed using the basilic-cephalic loop vein under peripheral nerve blockades. This anesthesia allowed a series of surgical revascularizations without general anesthesia, and the postoperative courses were uneventful. The patient survived for 4 years with ambulatory status. In conclusion, loop graft can be an alternative single vein material for distal bypass when no saphenous veins are available.
RESUMEN
A man in his 54 was admitted to our hospital owing to progressive postprandial pain for a month. Computed tomography (CT) scan and angiography revealed severe stenosis and calcification of the celiac artery, superior mesenteric artery, and inferior mesenteric artery. Based on the findings of CT scan and angiography, abdominal angina was established and retrograde revascularization was performed only to the superior mesenteric artery using an artificial graft. After the surgery, he remains free of postprandial abdominal pain.
