The surgical removal of a transplanted kidney following rejection or failure can be hazardous. A total of 110 grafts were removed consecutively in 84 patients (in 21 cases a second graft and in 5 cases a third graft was removed). Two surgical techniques were applied: extracapsular and intracapsular removal. The extracapsular technique was associated with complications in 11 out of 69 cases (16 per cent) and the intracapsular technique, in 3 out of 36 cases (8 per cent). In 5 cases the operative technique could not be determined from the records. In the 14 cases developing complications, wound infection was observed in 7 cases, wound haematoma in 4 and mycotic aneurysm, pulmonary embolism and clotting in the bladder each in 1 case. One patient (1.2 per cent) died due to late complications after allograft nephrectomy following rupture of a mycotic aortic aneurysm. The technique of kidney transplant removal by either the intra- or extra-capsular route of the exact timing of the operation are important features for safe treatment of patients with end-stage graft failure.

If feasible, the dorsomyocutaneous flap technique seems to be the treatment of choice in KD. Because the wound complication rate of the group with a dorsomyocutaneous flap and the percentage of amputee patients who received prosthesis after KD fell within the same range as TFA amputee patients, KD may be an appropriate alternative when surgeons consider a TFA.

WHAT THIS PAPER ADDS The new 2019 guideline of the European Society for Vascular Surgery recommends consideration for elective iliac artery aneurysm (IAA) repair when the iliac diameter exceeds 35 mm. This nationwide study from the Netherlands demonstrates that elective IAA repair is carried out at a median maximum diameter of 43 mm, and ruptured IAA repair at 68 mm. The findings appear to support the recent raise of the threshold diameter for elective IAA repair. Objective: The new 2019 guideline of the European Society for Vascular Surgery (ESVS) recommends consideration for elective iliac artery aneurysm (eIAA) repair when the iliac diameter exceeds 3.5 cm, as opposed to 3.0 cm previously. The current study assessed diameters at time of eIAA repair and ruptured IAA (rIAA) repair and compared clinical outcomes after open surgical repair (OSR) and endovascular aneurysm repair (EVAR). Methods: This retrospective observational study used the nationwide Dutch Surgical Aneurysm Audit (DSAA) registry that includes all patients who undergo aorto-iliac aneurysm repair in the Netherlands. All patients who underwent primary IAA repair between 1 January 2014 and 1 January 2018 were included. Diameters at time of eIAA and rIAA repair were compared in a descriptive fashion. The anatomical location of the IAA was not registered in the registry. Patient characteristics and outcomes of OSR and EVAR were compared with appropriate statistical tests. Results: The DSAA registry comprised 974 patients who underwent IAA repair. A total of 851 patients were included after exclusion of patients undergoing revision surgery and patients with missing essential variables. eIAA repair was carried out in 713 patients, rIAA repair in 102, and symptomatic IAA repair in 36. OSR was performed in 205, EVAR in 618, and hybrid repairs and conversions in 28. The median maximum IAA diameter at the time of eIAA and rIAA repair was 43 (IQR 38e50) mm and 68 (IQR 58e85) mm, respectively. Mortality was 1.3% (95% CI 0.7e2.4) after eIAA repair and 25.5% (95% CI 18.0e34.7) after rIAA repair. Mortality was not significantly different between the OSR and EVAR subgroups. Elective OSR was associated with significantly more complications than EVAR (intra-operative: 9.8% vs. 3.6%, postoperative: 34.0% vs. 13.8%, respectively). Conclusion: In the Netherlands, most eIAA repairs are performed at diameters larger than recommended by the ESVS guideline. These findings appear to support the recent increase in the threshold diameter for eIAA repair.
