Endovascular stent-graft implantation technique is a newly developed, effective and less invasive method in treating thoracic aortic dissection (TAD). Our study was designed to further verify the feasibility, the efficacy, and safety of this technique. We present a 4-year follow-up report of endovascular stent-graft treatment over 36 cases of acute TAD patients and 40 cases of chronic TAD patie...

We report a case of emergency endovascular stent-graft repair of a traumatic false aneurysm of the thoracic aorta. Thoracotomy was relatively contraindicated because the patient also sustained incomplete spinal injury, He recovered fully from both chest and spinal injuries, and remains without evidence of complications related to the stent-graft 18 months after the injury.

background the most important surgical complications of renal transplantation are stenosis and obstruction of anastomosis of the ureter to the bladder. hence, routine use of ureteral stents to prevent such complications seems logical; however, the optimal time to remove the ureteral stent is still controversial. objectives the purpose of this study was to compare the benefits and complications ...

We reported a 21-year-old patient with strict descending aorta coarctation and small post-ductal patent ductus arteriosus, complicated with abortion and hypertension. The patient was successfully treated by endovascular stent-graft with a single cardiac catheterization. Endovascular stent-graft is an easy, safe, and reliable intervention for the treatment of strict descending aorta coarctation ...

Whereas buckling can cause type III endoleaks, long-term twisting of a stent-graft was investigated here as a mechanism leading to type V endoleak or endotension. Two experimental device designs supported with Z-stents having strut angles of 35° or 45° were compared to a ringed control under accelerated twisting. Damage to each device was assessed and compared after different durations of twist...

Constitutive law for shape-memory alloys subjected to multi-axial loading, which is based on a semi-micromechanical integrated multi-plane model capable of internal mechanism observations, is generally not available in the literature. The presented numerical results show significant variations in the mechanical response along the multi loading axes. These are attributed to changes in the marten...

Contrast transesophageal echocardiography (cTEE) was superior to both TEE and angiography (ANGIO) alone in the assessment of slow flow and remaining flow in the false lumen/aneurysmal sac after stent-graft implantation and in the detection of incomplete stent-graft apposition. (A) TEE demonstrated the presence of type B dissection with evidence of malperfusion. After stent deployment and true l...

We reported a patient with Buerger's disease who presented with critical limb ischemiawith prior recurrent occlusions after multiple surgical and endovascular treatments. Total occlusion of the whole native femoropopliteal and infrapopliteal arteries was observed. The femoropopliteal bypass graft, as well as a stent that was implanted in the mid-popliteal artery, were also occluded. Because of ...

OBJECTIVES A new surgical technique named triple-branched stent graft was developed and reported to have excellent clinical results for Stanford type A aortic dissection. However, we found some potential risks, in our experience, of this technique. We compared this technique with total arch replacement combined with stented elephant trunk implantation in patients with acute Stanford type A diss...

Correspondence To the Editor: We report two cases of arch replacement combined with frozen elephant trunk implantation procedure using the collared anastomosis technique for giant arch and thoracic aorta dilatation. A 62‑year‑old hypertensive female patient was admitted because of endoleak after thoracic endovascular aortic repair (TEVAR). The patient underwent TEVAR procedure because of Stanfo...
