Cine-viewing of overlapping thin collimation images: an improved diagnostic tool in multislice helical CT of the bowel.

As compared to single slice helical CT, multislice helical CT does not only improve the quality of the individual images (in terms of slice sensitivity profile and image artifacts) and the range of scan coverage, it also enforces the CT postprocessing possibilities. The advantage of post-processing thin collimation bowel CT images with overlap and cine-viewing or paging is reported. The case report illustrates that cine-viewing of overlapping thin collimation images obtained with multislice helical CT, allows an excellent evaluation of the bowel loops resulting in the diagnosis of a perforated sigmoid carcinoma and its complications.

Traumatic pseudo-aneurysm and dissection of the thoracic aorta in the presence of an aberrant right subclavian artery: value of multi-slice helical CT.

A case of traumatic pseudo-aneurysm and dissection of the proximal descending thoracic aorta in association with an aberrant right subclavian artery and a common trunk for both common carotid arteries is presented. The diagnosis of this traumatic pseudo-aneurysm and dissection in association with these congenital anomalies by means of a multi-slice helical CT is discussed. To our knowledge, this is the first such case reported in the literature.

Thoracoscopic assisted lobectomy.

The advances in endoscopic capabilities expanded the potential role of laparoscopic and thoracoscopic surgery. The introduction of safe linear stapling devices made thoracoscopic assisted segmental lung resections possible. Because of the postoperative advantages of a thoracoscopic operation, a technique for thoracoscopic lobectomies was developed. Three case reports are presented using the same technique. The first two cases report a right lower lobectomy and the third case a bilobectomy, right middle and lower lobe.

Endovenous laser treatment for primary varicose veins.

Venous insufficiency of the lower extremities is a highly prevalent condition. Successful treatment of superficial venous insufficiency will most often necessitate treatment of the saphenofemoral junction incompetence with correction of saphenous vein reflux. In the majority of patients it concerns a reflux of the greater saphenous vein. The standard procedure consists of ligation and stripping of the greater saphenous vein combined with with additional phlebectomies or ligation of insufficient perforant veins if necessary. Although the standard procedure is widely known and accepted, the postoperative morbidity and postoperative limitations of activity are high. In this context minimally invasive percutaneous endovenous techniques were developed to improve the patients comfort and faster resumption of work. Among these, endovenous laser ablation of the greater saphenous vein is a relatively new procedure. Percutaneous introduction of a laser fiber into the incompetent vein and ablation with pulsed laser energy is far less invasive than stripping.
