1/2. Anterior perforations in lumbar discectomies. A report of four cases of vascular complications and a CT study of the prevertebral lumbar anatomy.

    Four cases of vascular complications to anterior perforations during discectomy prompted a CT study to measure lumbar disc diameters and to evaluate the prevertebral anatomy. Fifty young adults who had been referred for low-back pain and/or sciatica but had not undergone operation were included. In five additional patients, prone versus supine CT examinations were compared. Six typical configurations of the vascular anatomy could be classified to explain the type of vascular complications occurring at the L3-4 and L4-L5 disc levels. The sagittal diameter of the three lowest lumbar discs varied from 33 to 56 mm, indicating the importance of this parameter as an intraoperative guideline for the spine surgeon. air-filled intestines were observed anterior to the L5-S1 disc predominantly in the prone position. The possible relationship between this finding and postoperative discitis is discussed.

2/2. Potential complications of vascular stapling in thoracoscopic pulmonary resection.

    In a series of 57 patients undergoing thoracoscopic pulmonary lobectomy, 2 required expeditious conversion to open thoracotomy when a stapling device (Endo-GIA 30 V3; Autosuture, Ascot, UK) used on the main right lower pulmonary artery in 1 case and on the left superior pulmonary vein in the other cut but failed to staple the vessel involved. In both instances the vessel was successfully controlled while a thoracotomy was performed and the involved vessel was oversewn. Both patients made an uncomplicated postoperative recovery. As the number of thoracoscopic pulmonary resections increases, it is likely that similar episodes will occur in the future. These cases strongly emphasize the fact that patients undergoing this procedure should do so in a center specializing in thoracic surgery where there is the necessary surgical expertise and equipment to deal with such potentially life-threatening vascular complications.
