Total laparoscopic abdominal aortic aneurysm repair with reimplantation of the inferior mesenteric artery

AbstractWe performed a total laparoscopic reimplantation of the inferior mesenteric artery (IMA) during laparoscopic infrarenal aortic aneurysm repair. The postoperative course was uneventful, and angiograms showed a patent IMA after reimplantation. To our knowledge, total laparoscopic reimplantation of the IMA in human beings has not previously been described

Total laparoscopic infrarenal aortic aneurysm repair: Preliminary results

ObjectivesWe describe our initial experience of total laparoscopic abdominal aortic aneurysm (AAA) repair.Material and methodsBetween February 2002 and September 2003, we performed 30 total laparoscopic AAA repairs in 27 men and 3 women. Median age was 71.5 years (range, 46-85 years). Median aneurysm size was 51.5 mm (range, 30-79 mm). American Society of Anesthesiologists class of patients was II, III and IV in 10, 19, and 1 cases, respectively. We performed total laparoscopic endoaneurysmorrhaphy and aneurysm exclusion in 27 and 3 patients, respectively. We used the laparoscopic transperitoneal left retrocolic approach in 27 patients. We operated on 2 patients via a tranperitoneal left retrorenal approach and 1 patient via a retroperitoneoscopic approach.ResultsWe implanted tube grafts and bifurcated grafts in 11 and 19 patients, respectively. Two minilaparotomies were performed. In 1 case, exposure via a retroperitoneal approach was difficult and, in another case, distal aorta was extremely calcified. Median operative time was 290 minutes (range, 160-420 minutes). Median aortic clamping time was 78 minutes (range, 35-230 minutes). Median blood loss was 1680 cc (range, 300-6900 cc). In our early experience, 2 patients died of myocardial infarction. Ten major nonlethal postoperative complications were observed in 8 patients: 4 transcient renal insufficiencies, 2 cases of lung atelectasis, 1 bowel obstruction, 1 spleen rupture, 1 external iliac artery dissection, and 1 iliac hematoma. Others patients had an excellent recovery with rapid return to general diet and ambulation. Median hospital stay was 9 days (range, 8-37 days). With a median follow-up of 12 months (range, 0.5-20 months), patients had a complete recovery and all grafts were patent.ConclusionThese preliminary results show that total laparoscopic AAA repair is feasible and worthwhile for patients once the learning curve is overcome. However, prior training and experience in laparoscopic aortic surgery are needed to perform total laparoscopic AAA repair. Despite these encouraging results, a greater experience and further evaluation are required to ensure the real benefit of this technique compared with open AAA repair

Conversion From an Outpatient to an Inpatient Setting After an Endovascular Treatment for Lower Extremity Artery Disease

International audienceBackground: Outpatient endovascular treatment (EVT) for lower extremity artery disease (LEAD) is increasing. Some patients will, nonetheless, unexpectedly stay hospitalized for the night after the procedure. The purpose of this study was to identify the factors associated with a conversion from an outpatient setting (OS) to an inpatient setting (IS). Methods: From April 2017 to August 2019, we performed 745 EVT for LEAD. Patients scheduled for a same-day discharge procedure were retrospectively analyzed. The factors potentially associated with a conversion to an IS were assessed. Results are expressed as odds ratio (OR) with 95% confidence intervals. Results: Among the 198 (26.6%) patients scheduled for outpatient EVT, mean age was 70.8±14.1 years old, 34.3% had an ASA score≥3 and 38.4% presented a chronic limb-threatening ischemia. Twenty-eight patients (14.1%) were converted from an OS to IS. Univariate analysis found that Rutherford stage≥4 (OR = 5.09 [2.11–12.27], P < 0.001), high blood pressure (OR = 3.19 [1.06–9.63], P = 0.040), ASA score≥3 (OR = 3.61 [1.58–8.24], P = 0.002), duration of procedure ≥90 min (OR = 2.36, [1.03–5.39], P = 0.042), anterograde puncture (OR = 2.94, [1.30–6.66], P = 0.009), arrival in the operating room ≥12:00 (OR = 13.05, [5.29–32.17], P < 0.001) and general anesthesia (OR = 3.89, [1.20–12.62], P = 0.024) were associated with a conversion. The multivariate analysis revealed that an arrival in the operative room ≥12:00 (OR = 11.71, [3.85–35.60], P < 0.001) and general anesthesia (OR = 6.76, [1.28–35.82], P = 0.009) were independent factors associated with a conversion. Conclusion: Arrival in the operative room after 12:00 and general anesthesia represent two independent correctible factors associated with the risk of OS failure. No factor directly related to comorbidities or the LEAD severity was identified

Endovascular Repair of Narrow Distal Aortas Using an In Situ Fenestration Technique

International audiencePurpose: To demonstrate that in situ fenestration (ISF) of an aorto-uni-iliac endograft to treat aortoiliac disease with narrow distal aorta (NDA) vessels is effective and safe. Materials and Methods: Data for all patients treated by use of ISF between August 2014 and December 2019 were retrospectively analyzed. The series included 27 patients, aged 70 years ± standard error (SE) 11. The pathologies treated included aortoiliac occlusive disease (n = 16), asymptomatic abdominal aortic aneurysm (n = 8), and a ruptured abdominal aortic aneurysm (n = 3). The technique consisted of deploying an aorto-uni-iliac graft, which was converted into a bifurcated repair through contralateral iliac ISF. The inclusion criteria encompassed the presence of an abdominal aortic aneurysm (diameter of >50 mm, rapid growth, ruptured or symptomatic) associated with NDA or the presence of severe aortoiliac occlusive disease with NDA. NDA is defined as an aortic diameter of <16 mm. Results: The mean aortic bifurcation diameter was 11.9 mm ± SE 1.5. In total, 55% of the fenestrated endografts were performed with a multifilament polyester endograft and 45% with expanded polytetrafluoroethylene endograft. Technical success was 100%. Fluoroscopy time was 28 minutes ± SE 12, and 94 mL ± SE 43 of iodinated contrast medium was used. In the postoperative course, a single minor retroperitoneal hematoma was identified. The mean hospital stay was 5 days ± SE 3. At the mean follow-up of 26 months ± SE 22, overall primary patency was 94% and no endoleak was observed at the ISF site. Conclusions: The ISF technique is safe and effective in the treatment of aortoiliac disease with NDA. Comparisons with alternative techniques are needed to determine the long-term durability

Endovascular Treatment of Long Femoropopliteal Lesions with Contiguous Bare Metal Stents

International audienceObjectives: Recent controversies on the use of drug coated/eluting devices in the arteries of the lower extremities renewed the focus on the evaluation of more conventional techniques. The results of the stenting of short and/or intermediate femoro-popliteal lesions are well known, but little data relate to the endovascular treatment of long femoro-popliteal lesions with contiguous bare metal stents (ETLFBS). The objective of this study was to report our results of ETLFBS. Material and Methods: Between January 2014 and December 2017, 1233 patients had an infrainguinal angioplasty in our center. The files of patients treated for femoropopliteal lesions longer than 250 mm using extensive stenting with contiguous bare metal stents were reviewed and analyzed. The primary outcome was the 12-month primary patency, defined by the absence of restenosis (≥50%) and/or reintervention on the target lesion. Continuous data were expressed as mean and standard deviation. Survival analysis was carried out according to Kaplan-Meier. Results: Overall, 64 patients aged 80 ± 11 years were included, with 49 (76.6%) presenting with critical limb ischemia. Lesions were classified as TASC D in 54.7% of the cases. The length of the lesions was 295 ± 64 mm and 3 ± 1 stents were implanted. The 30-day mortality was null but two patients (3.1%) presented nonvascular major complications. With a follow-up of 27 ± 17 months, 22 patients (34.3%) died including three of vascular causes. The healing of the trophic disorder was obtained in 77.5% of the cases. The rate of amputation was 10.9%. The 6-, 12-, and 24-month primary patency rates were 79.7%, 66.6%, and 60.9%, respectively. The 6-, 12-, and 24-month rates of freedom from target lesion revascularization were 96.3%, 73.9%, and 71.9%, respectively. The 6-, 12-, and 24-month survival rates were 90.3%, 83.6%, and 65.6%, respectively. Conclusions: The 12-month primary patency rate of ETLFBS is acceptable. This strategy constitutes an acceptable alternative in patients presenting with critical limb ischemia and a limited life expectancy
