Acute Venous Iliofemoral Thrombosis: Early Surgical Thrombectomy Is Effective and Durable.

Background: The first-line recommendation for the treatment of acute iliofemoral deep vein thrombosis (IFDVT) is catheter-directed thrombolysis or pharmacomechanical thrombolysis. Recent analysis of surgical thrombectomy has shown comparable results. However, this procedure is not commonly given as much importance as interventional techniques.

Oncological short-term effects and adverse events of MRI-guided selective neoadjuvant radiochemotherapy for rectal cancer.

Aim: To investigate the oncological short-term effects and acute side-effects of magnetic resonance imaging (MRI)-guided selective neoadjuvant radiochemotherapy (nRCT) for rectal cancer.

Patients And Methods: In a prospective multicenter cohort study of 230 patients with rectal cancer stage II or III, nRCT was applied in the following situations (n=96) only: cT4 tumors, cT3 tumors of the distal rectum or tumors leaving a circumferential resection margin (CRM) of ≤1 mm between the tumor and the mesorectal fascia (mrCRM+). Pre-therapeutical tumor stage and involvement of mesorectal fascia were assessed by MRI and were compared with the pathological findings of the rectal specimens.

Pulmonary vein thrombosis after lower lobectomy of the left lung.

Pulmonary vein thrombosis is a known complication after lung transplantation but has rarely been reported after lobectomy or bilobectomy. We report the case of a left upper pulmonary vein thrombosis following an uneventful left lower lobectomy for bronchial carcinoma. Postoperative arterial blood gas values and chest radiographs were normal.

PPS-PEG surface coating to reduce thrombogenicity of small diameter ePTFE vascular grafts.

Aims: Patency failure of small vascular synthetic grafts is still a major problem for coronary and peripheral revascularization. Thus, three new surface coatings of small synthetic grafts were tested in an acute pig model to evaluate their thrombogenicity (extracorporeal arterio-venous shunt) and in a chronic rat model to evaluate the tissue reaction they induced (subcutaneous implantation).

Methods: In five domestic pigs (25-30 kg) an extracorporeal femoro-femoral arterio-venous shunt model was used.

The role of contrast-enhanced spiral CT imaging versus chest X-rays in surgical therapeutic concepts and thoracic aortic injury: a 29-year Swiss retrospective analysis of aortic surgery.

Background: Blunt chest trauma accounts for 90% of chest trauma in the civilian population in Europe and the United States and causes 20% of trauma-related deaths. Missed aortic injuries can rupture and lead to subsequent death of the patient.

Materials And Methods: This retrospective study compared two different imaging strategies, chest X-rays compared to additional contrast-enhanced spiral CT imaging, in patients suffering from blunt thoracic trauma.

Clinical experience with autologous endothelial cell-seeded polytetrafluoroethylene coronary artery bypass grafts.

Objective: Autologous endothelial cell seeding was used to improve the patency of 4-mm polytetrafluoroethylene vascular prostheses.

Methods: Since 1995, 14 patients with coronary artery disease received 21 autologous endothelial cell-seeded polytetrafluoroethylene vascular bypass grafts for coronary artery revascularization. The polytetrafluoroethylene grafts were seeded with the endothelial cells in a multiple step procedure, including cell culture techniques before coronary bypass operation.

Iron- and ascorbic acid-induced lipid peroxidation in renal microsomes isolated from rats treated with platinum compounds.

Renal microsomes isolated on day 3 from cisplatin (CDDP, single i.p. injection, 4 or 6 mg/kg)-treated rats were monitored for their susceptibility to lipid peroxidation as compared with microsomes from rats treated with carboplatin (CBDCA, 30 mg/kg), transplatin (TDDP, 6 mg/kg) or CDDP hydrolysis products (4 or 6 mg/kg) or from control animals.
