ABSTRACT
PURPOSE:
To describe the semibranch as new tool to treat patients with thoracoabdominal, para- and juxtarenal aortic pathologies. TECHNIQUE The technique is demonstrated in 2 patients with aortic pathologies. First, a 76-year-old woman with a type Ia endoleak after endovascular repair of abdominal aneurysm (EVAR). Due to the short mainbody of the EVAR and suprarenal extension of the pathology, a 4-branched device with integrated bifurcation was chosen. To realize a branched device in small diameters of the suprarenal aorta, 2 semibranches, for the superior mesenteric artery (SMA) and the celiac trunc (CT), were planned. The second patient, a 75-year-old man, had a juxtarenal aneurysm. Due to small diameters of the aorta, semibranches for the SMA and the CT were planned. In both cases, a total transfemoral approach was used with a steerable sheath. Placement, cannulation of the semibranch, forwarding of the bridging stentgraft, and sealing was uneventful. All 4 semibranches were successful in sealing the aneurysm.CONCLUSION:
The semibranch is another tool in the armamentarium of the endovascular interventionalist, which can expand the range of patients that can be treated. Especially patients with small aortic diameter or short distances between target vessels with the same offspring angle can profit from the semibranch design. CLINICAL IMPACT The semibranch is a new tool to treat thoracoabdominal as well para- and juxtarenal aortic pathologies. Due to its reduced length, packaging density can be higher and diameter of the stentgraft can be larger. It closes the gap in pathologies where fenestration are not suitable (kinked aortas) and there is not enough space for standard inner branches (small diameters).
