Type IV thoracoabdominal aneurysm repair: predictors of postoperative mortality, spinal cord injury, and acute intestinal ischemia.

Our purpose was to identify preoperative and intraoperative predictors of early mortality, spinal cord injury, or acute intestinal ischemia after repair of type IV thoracoabdominal aneurysm (TAA IV) as a basis for optimizing surgical indications and techniques. From January 1991 to June 2006 we operated on 171 patients for TAA IV. There were 149 men (87.

Extensive unilateral iliofemoral occlusions: durability of four techniques of arterial reconstructions.

In patients with long unilateral iliofemoral occlusive disease unfit for percutaneous transluminal angioplasty (PTA), most surgeons would choose some type of prosthetic bypass (aortounifemoral, iliofemoral or cross over). All these bypasses would provide excellent early results, but some may not be sufficient in patients with a good life expectancy who also need durable patency. The purpose of the study was to compare the long-term results of four types of arterial reconstructions.

Early transient hydronephrosis after laparoscopic aortobifemoral bypass grafting.

Hydronephrosis early after aorto-bifemoral bypass grafting is probably an underestimated complication. We describe early and transient hydronephrosis that developed in two patients after totally laparoscopic aorto-bifemoral bypass surgery to treat aortoiliac occlusive disease. A conservative approach to treatment was adopted, and both patients recovered.

Totally laparoscopic juxtarenal aortic anastomosis: an experimental study.

The surgical management of juxtarenal aneurysms necessitates suprarenal aortic clamping and control of the renal arteries. We attempted to reproduce this procedure laparoscopically. Five female piglets were submitted to a totally laparoscopic approach of the aortoiliac segment.

Endovascular procedures under near-real-time MRI guidance: present status and future perspectives.

Indications for endoluminal treatment of occlusive aorto-iliac disease are well known. Endovascular grafting is a technique currently being evaluated for its efficacy for treatment of aneurysmal disease. The success of those techniques is due to their favorable results and non-invasive characteristics.
