We developed an umbilical zigzag skin incision technique to perform abdominal laparoscopic operations using a GelPort, with a minimal number of skin incisions. We consider that our method reduces the technical difficulties associated with laparoscopic surgery and maintains cosmesis.

A 4-year-old male Japanese Shiba Inu presented with recurrent chylothorax. The thoracic duct was successfully imaged using computed tomography after the injection of an iodine contrast agent into the subcutaneous tissue surrounding the anus. The thoracic duct was successfully ligated and pericardectomy performed via an open thoracotomy. Pleural effusion improved but relapsed a week after the surgery. A second lymphography revealed a collateral thoracic duct that was not detected during the first lymphography. The collateral duct was ligated and chylothorax was resolved after the second surgery. The lymphography applied in this study was minimally-invasive and easily provided images of the thoracic duct in a dog with chylothorax.

There was a significant change in the neck angle between the preoperative condition and the immediate postoperative condition. However, there was no clear relationship found between the angle of the neck and the proximal stent-graft migration. Postoperative changes in the proximal neck angle just after EVAR and subsequent temporal changes during a 2-year follow-up period do not appear to predict stent-graft migration, secondary intervention rates, or the occurrence of endoleak.

A 79 year-old female with left buttock and thigh pain was diagnosed as persistent sciatic artery aneurysm (PSAA) by CT. On the following day she had her left lower limb pain caused by embolic ischemia. Distal embolization was treated by transcatheter thrombus suction and thrombolytic therapy. A Viabahn (W.L. Gore, AZ, USA) was deployed to exclude the PSAA. Although the lower limb pain was alleviated, the stent graft occluded in the early postoperative period and caused intermittent claudication. As the long term results of stent graft placement for persistent sciatic artery is unknown, the indication should be carefully considered.
