RESUMEN
PURPOSE: Common femoral artery (CFA)-occlusive disease has traditionally been treated with open surgery, yet nowadays the frailty of patients has induced to find new techniques of revascularisation by endovascular means. So far, intravascular lithotripsy (IVL) has shown promising results in several lower limbs arterial districts. The purpose of this article is to report our experience with IVL for severely calcified peripheral arterial disease (PAD) of the CFA. METHODS: From November 2018 and October 2020, 10 consecutive patients (12 limbs) treated with IVL were prospectively enrolled in a dedicated database. Inclusion criteria were CFA localization of PAD, with a severe degree of calcification, a lesion length ≥10 mm, and a degree of stenosis ≥70% (severe). The only admitted adjunctive treatment was drug-coated balloon (DCB) angioplasty. Primary outcomes were technical and procedural success, clinical success, and target lesion revascularisation (TLR). Secondary outcomes were target extremity revascularisation (TER) and major adverse events (MAEs). RESULTS: All patients underwent IVL with associated DCB angioplasty. The median percentage of achieved stenosis reduction was 55.5% (interquartile range [IQR] 50-60.75), with a technical and procedural success of 100%. Over the study period, TLR only occurred in one limb (8.3%), with a mean upgrade in Rutherford class of 2.7 ± 0.77. No target vessel and access site complications were reported, as well as no distal embolization. One death and one major amputation occurred over the follow-up period, both in the same patient. CONCLUSIONS: Based on our experience, IVL for selected cases of severely calcified CFA disease, associated with DCB angioplasty, may be considered a safe and effective technique. Of course, a long-term follow-up and a larger series of patients are needed to validate our results.

Laparoscopy is a minimally invasive alternative for type II endoleak repair after endovascular aneurysm repair. However, control of lumbar and median sacral arteries is considered technically difficult due to the dense inflammatory tissue surrounding the aorta. We describe a technical tip that avoids close dissection of the aneurysm sac. After the transperitoneal approaches we commonly use during laparoscopic aortic surgery, the aneurysm is drawn rightward to access the plane of the anterior longitudinal ligament. This technique allows a direct exposure of the lumbar and median sacral arteries, which are all methodically dissected and ligated along the anterior wall of the spine without close dissection of the aneurysm sac. In our experience, this technical tip was always feasible and simplified laparoscopic type II endoleak repair.

Herein, we report a 26-year-old patient with lymphangiomatosis of the spleen associated with multiple lymphatic and venous malformations. This patient underwent excision of a large lymphatic malformation of the left abdominal wall during childhood. A venous malformation of her left lower limb was excised during adolescence. Additional lymphatic malformations were found in the soft tissue of her left thigh at the age of 20. During hospitalization for a huge vulvar hemangioma at the age of 26, she was incidentally found to have asymptomatic splenomegaly, for which she underwent splenectomy. Examination of the spleen revealed diffuse involvement by a lymphatic anomaly predominantly forming small cystic spaces. Lymphangiomatosis of the spleen is rare and is classically separated into an isolated or pure form and a generalized form when it is associated with involvement of other viscera and/or multiple soft-tissue planes. This patient was affected by a borderline form of splenic lymphangiomatosis with limited somatic involvement of the superficial soft tissues and blood vessels. Notably, all the additional vascular malformations in this patient were left sided, and at this time there was no additional involvement of internal organ. No hereditary or known syndrome was identified.

Endovascular repair of chronic aortic dissections (CAD) intend to promote false lumen thrombosis (FLT). This article describes a technique using Amplatzer vascular plugs (AVPs) for entry tear closure of CAD. A 70-year-old man presented with a type II dissecting thoracoabdominal aneurysm. Computed tomography scan showed a very tight true lumen, partial FLT, and 2 entry tears at the level of the left subclavian artery and the visceral aorta, respectively. During a first procedure, aortic debranching was performed using the ascending aorta as bypass inflow. In a second intervention entry tears were closed using AVPs protected by short stent grafts. Technical success was achieved. No paraplegia occurred. Eighteen months later, FLT was complete and aortic diameter decreased. Entry tear closure using AVPs is feasible and allows FLT. Further reports are needed to determine if stent-graft protection of AVPs is mandatory, which may simplify technical aspects of the procedure.

BACKGROUND: In the last decade, advances in surgical techniques, and the introduction of adjuncts for organ protection, have modified the approach for thoracoabdominal aortic aneurysm (TAAA) surgical repair. The aim of this study is to determine whether the contemporary approach influenced the outcomes. METHODS: From 1989 to 2022, patients who had received elective open surgical repair (OSR) for TAAA at our institution were retrospectively analyzed. This series has been divided in two groups: Group 1 (1989-2009), and Group 2 (2010-2022). Patients included in Group 1 were those treated with a selective use of adjuncts, and Group 2 included patients treated with the systematic use of adjuncts. RESULTS: A total of 1107 patients were treated (Group 1: 455; Group 2: 652). The surgical management was significantly different between the two groups. The in-hospital mortality was significantly different between the two groups (Group 1: 13.4%, Group 2: 8.1%; p 0.004), as was the rate of permanent spinal cord ischemia (Group 1: 11.9%, Group 2: 7.8%; p 0.023). Renal and respiratory failure were reduced in Group 2, but not significantly. CONCLUSIONS: The use of the adjuncts enabled the achievement of improvement in mortality and SCI prevention in TAAA OSR. Although a refined surgical technique, mortality and morbidity are still noteworthy in this complex aortic field.
RESUMEN
BACKGROUND: Identifying sex-related differences/variables associated with 30 day/1 year mortality in patients with chronic limb-threatening ischemia (CLTI). METHODS: Multicenter/retrospective/observational study. A database was sent to all the Italian vascular surgeries to collect all the patients operated on for CLTI in 2019. Acute lower-limb ischemia and neuropathic-diabetic foot are not included. FOLLOW-UP: One year. Data on demographics/comorbidities, treatments/outcomes, and 30 day/1 year mortality were investigated. RESULTS: Information on 2399 cases (69.8% men) from 36/143 (25.2%) centers. Median (IQR) age: 73 (66-80) and 79 (71-85) years for men/women, respectively (p < 0.0001). Women were more likely to be over 75 (63.2% vs. 40.1%, p = 0.0001). More men smokers (73.7% vs. 42.2%, p < 0.0001), are on hemodialysis (10.1% vs. 6.7%, p = 0.006), affected by diabetes (61.9% vs. 52.8%, p < 0.0001), dyslipidemia (69.3% vs. 61.3%, p < 0.0001), hypertension (91.8% vs. 88.5%, p = 0.011), coronaropathy (43.9% vs. 29.4%, p < 0.0001), bronchopneumopathy (37.1% vs. 25.6%, p < 0.0001), underwent more open/hybrid surgeries (37.9% vs. 28.8%, p < 0.0001), and minor amputations (22% vs. 13.7%, p < 0.0001). More women underwent endovascular revascularizations (61.6% vs. 55.2%, p = 0.004), major amputations (9.6% vs. 6.9%, p = 0.024), and obtained limb-salvage if with limited gangrene (50.8% vs. 44.9%, p = 0.017). Age > 75 (HR = 3.63, p = 0.003) is associated with 30 day mortality. Age > 75 (HR = 2.14, p < 0.0001), nephropathy (HR = 1.54, p < 0.0001), coronaropathy (HR = 1.26, p = 0.036), and infection/necrosis of the foot (dry, HR = 1.42, p = 0.040; wet, HR = 2.04, p < 0.0001) are associated with 1 year mortality. No sex-linked difference in mortality statistics. CONCLUSION: Women exhibit fewer comorbidities but are struck by CLTI when over 75, a factor associated with short- and mid-term mortality, explaining why mortality does not statistically differ between the sexes.
RESUMEN
Background: To investigate the effects of the COVID-19 lockdowns on the vasculopathic population. Methods: The Divisions of Vascular Surgery of the southern Italian peninsula joined this multicenter retrospective study. Each received a 13-point questionnaire investigating the hospitalization rate of vascular patients in the first 11 months of the COVID-19 pandemic and in the preceding 11 months. Results: 27 out of 29 Centers were enrolled. April-December 2020 (7092 patients) vs. 2019 (9161 patients): post-EVAR surveillance, hospitalization for Rutherford category 3 peripheral arterial disease, and asymptomatic carotid stenosis revascularization significantly decreased (1484 (16.2%) vs. 1014 (14.3%), p = 0.0009; 1401 (15.29%) vs. 959 (13.52%), p = 0.0006; and 1558 (17.01%) vs. 934 (13.17%), p < 0.0001, respectively), while admissions for revascularization or major amputations for chronic limb-threatening ischemia and urgent revascularization for symptomatic carotid stenosis significantly increased (1204 (16.98%) vs. 1245 (13.59%), p < 0.0001; 355 (5.01%) vs. 358 (3.91%), p = 0.0007; and 153 (2.16%) vs. 140 (1.53%), p = 0.0009, respectively). Conclusions: The suspension of elective procedures during the COVID-19 pandemic caused a significant reduction in post-EVAR surveillance, and in the hospitalization of asymptomatic carotid stenosis revascularization and Rutherford 3 peripheral arterial disease. Consequentially, we observed a significant increase in admissions for urgent revascularization for symptomatic carotid stenosis, as well as for revascularization or major amputations for chronic limb-threatening ischemia.
RESUMEN
Chimney/snorkel endovascular aneurysm repair (Ch-EVAR) enables the minimally invasive treatment of abdominal aortic aneurysm in anatomically challenging and high-risk surgical cases. Here, we present the case of a 77-year-old man with an abdominal aortic aneurysm associated with crossed fused renal ectopia and an ectopic renal artery arising directly from the aneurysm sac. After successful implementation of Ch-EVAR, computed tomography angiography at 18 months revealed no endoleaks, patency of the parallel graft, and normal renal vascularization and function. This report underscores the feasibility of Ch-EVAR in a case with high anatomic complexity.
RESUMEN
Elective bilateral exposure of iliac arteries during endovascular or laparoscopic aneurysm repair is commonly performed through two retroperitoneal incisions in the iliac fossa. Larger incisions are necessary when simultaneous external and common iliac exposures are needed. We describe a new technique using a single incision for bilateral approach of the iliac arteries. Exposure of iliac arteries through this bilateral anterior paramedian retroperitoneal approach allows the introduction of endografts, crossover ilioiliac bypass, implantation of graft limbs for bifurcated bypass grafting, reconstruction of internal iliac arteries, and ligature of iliac arteries.

OBJECTIVES: This study describes our experience of total laparoscopic juxtarenal abdominal aortic aneurysm (JAAA) repair. METHODS: Between February 2002 and October 2007, we performed 148 total laparoscopic AAA repairs, including a subset of 13 patients who underwent a laparoscopic JAAA repair. Median age was 70 years (range, 50-81years). Median aneurysm size was 55 mm (range, 50-80 mm). Eight patients were in American Society of Anesthesiologist class II, and five were in class III. We used laparoscopic transperitoneal left retrorenal approaches and suprarenal clamping in all patients. RESULTS: We implanted tube grafts in nine patients and bifurcated grafts in four. No conversions to open repair were required. Median operative time was 260 minutes (range, 180-355 minutes). Total median aortic clamping time was 77 minutes (range, 36-105 minutes). Median suprarenal clamping time was 24 minutes (range, 9-37 minutes). Median blood loss was 855 mL (range, 215-2100 mL). No patients died. One patient had a postoperative coagulopathy with hemorrhagic syndrome. Five patients had moderate systemic complications, including four renal insufficiencies without dialysis and one grade I ischemic colitis. Liquid diet was reintroduced after 1 day (range, 1-7 days). Most patients were ambulatory by day 3 (range, 2-17 days). Median lengths of stay were 48 hours (range, 12-336 hours) in the intensive care unit and 10 days (range, 4-30 days) in the hospital. With a median follow-up of 19 months (range, 1-36 months), patients had complete recovery without graft anomalies. CONCLUSION: Total laparoscopic JAAA repair is feasible and worthwhile for patients. Prior experience in laparoscopic aortic surgery is essential to perform these challenging procedures. Despite these encouraging results, a greater experience is required to ensure the benefit of this technique compared with open repair.

An extra-anatomic bypass initiating from the ascending aorta, namely the ventral aorta, is a possible alternative for lower limb revascularization. However, acceptance of this technique is limited by the need of a median sternotomy and clamping of the ascending aorta. We report a new technique for the ventral aorta using a total videoscopic approach of the ascending aorta, which avoids the need for a median sternotomy. We discuss the advantages and perspectives of this new approach.

PURPOSE: This study was designed to identify differences in the per- and postoperative outcomes between total laparoscopic and open surgical repair of abdominal aortic aneurysms (AAA). METHODS: We reviewed 30 patients who underwent total laparoscopic AAA repair between July 2003 and December 2004 (group I). This group was matched in a case-control fashion by AAA morphology and American Society of Anesthesiologists class with a group of 30 patients who underwent conventional AAA repair between April 1997 and May 2004 (group II). Proportions and categoric data were compared with a chi(2) test. Continuous data were compared with a Mann-Whitney test. RESULTS: The two groups had comparable characteristics of age and cardiovascular risk factors. The number of tube and bifurcated grafts was 13 for group I and 17 for group II. Median operative time was 255 minutes (range, 170 to 410 minutes) in group I and 200 minutes (range, 130 to 410) in group II (P <.001). Median aortic clamping time was 80 minutes (range, 35 to 110 minutes) in group I and 50 minutes (range, 24 to 150 minutes) in group II (P < .0001). Total blood loss was 1600 mL (range, 400 to 4000 mL) for group I vd 1000 mL (range, 100 to 2900) for group II (P < .01). The mortality rate was 3.3% for group I (1 patient) vs 6.6% (2 patients) for group II (NS). There were no significant differences between the two groups in terms of postoperative systemic complications (23.3% vs 30%, NS) and local and vascular complications (10% vs 3.3%). Duration of ileus (2 vs 3 days, P < .05), return to normal diet (4 vs 8 days, P < .0001), day of ambulation (3 vs 4 days, P < .05) and dose of narcotics (3.5 mg vs 28.5 mg, P < .05) were significantly lower in group I. Median length of intensive care unit stay was similar between the two groups (48 hours). Median hospital stay was lower in group I but without significant differences with group II (9 vs 11 days, NS). CONCLUSION: This case-control study provides preliminary results that short-term outcomes of total laparoscopic AAA repair are comparable with those of open surgery. Peroperative data demonstrate that laparoscopy is more technically demanding than open repair. However, the technical challenge of laparoscopy does not worsen the postoperative course.

We report our initial experience with total laparoscopic repeat aortic surgery between June 2002 and October 2003. There were 4 patients, 3 men and 1 woman, ages 83, 67, 49, and 61 years, respectively. First operations were performed to treat aortoiliac occlusive disease. Repeat aortic surgery was indicated to treat para-anastomotic aneurysms (n = 2) and graft occlusion (n = 2). All patients underwent total laparoscopic surgery. There were no postoperative deaths. Only 1 patient had postoperative complications that required complementary surgical treatment. All patients were alive with patent revascularization after a mean follow-up of 14, 17, 20, and 12 months, respectively.

OBJECTIVES: We describe our experience with a new technique of total laparoscopic bypass surgery to treat aortoiliac occlusive lesions. MATERIAL AND METHODS: From November 2000 to December 2003, 93 total laparoscopic bypass procedures were performed to treat TASC (TransAtlantic Inter-Society Consensus document) grade C or D aortoiliac occlusive lesions. We also reimplanted 2 inferior mesenteric arteries, and performed 3 prosthesis-superior mesenteric bypasses and 2 suprarenal aorta endarterectomies. Our technique includes a sloping right lateral decubitus installation, which enables a simple transperitoneal left retrocolic or retrorenal approach to the infrarenal abdominal aorta. In patients with a hostile abdomen a retroperitoneal videoscopic approach was used. Aorta-prosthesis laparoscopic anastomoses are performed simply, which averts any trauma to the suture material. RESULTS: Patients included 76 men and 17 women, with median patient age 61 years (range, 38-79 years). The approach to the aorta was always possible, in particular, in obese patients. It enabled stable aortic exposure during performance of the laparoscopic aorta-prosthesis anastomosis. Median operative time was 240 minutes (range, 150-450 minutes). Median aortic clamping time measured to unclamping of the first prosthetic limb was 67.5 minutes (range, 30-135 minutes). Median duration of aorta-prosthesis anastomosis was 30 minutes (range, 12-90 minutes). The longest durations were mainly observed during the learning curve. Thirty-day postoperative mortality was 4% (4 of 93 patients). Two patients died of myocardial infarction. One patient with American Society of Anesthesiologists grade 4 disease operated on to treat critical ischemia died of multiple organ system failure, and 1 patient died of colonic ischemia. Major nonlethal postoperative complications were observed in 4 patients, and included lung atelectasia in 2 patients, graft infection in 1 patient operated on emergently to treat aortic occlusion, and secondary spleen rupture at day 5 in 1 patient. Median hospital stay was 7 days (range, 2-57 days). With a mean follow-up of 19 months (range, 1-37 months), complete recovery was observed in 89 patients, and all grafts were patent. One patient had kinking of a prosthetic limb at the groin, and in 1 patient Staphylococcus epidermidis graft infection developed, which was treated with in situ replacement with a rifampin-bonded graft. CONCLUSION: Total laparoscopic aortic bypass is feasible. In patients with TASC C and D aortoiliac occlusive lesions, short-term outcomes are comparable to those with conventional aortic bypass. After the initial learning curve, laparoscopic technique may reduce the operative trauma of aortic bypass.

OBJECTIVES: We describe our initial experience of total laparoscopic abdominal aortic aneurysm (AAA) repair. MATERIAL AND METHODS: Between 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. RESULTS: We 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. CONCLUSION: These 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.
