RESUMO

OBJECTIVE: The aim of this study was to compare the long term efficacy of lower limb bypass with that of endovascular treatment (EVT) in patients with chronic limb threatening ischaemia (CLTI). METHODS: This retrospective, multicentre study evaluated the outcomes of patients with CLTI who underwent first time infra-inguinal bypass or EVT. The primary outcome was to compare amputation free survival (AFS) rates between the two propensity score matched groups. The secondary outcome was to compare wound healing within the first six months. Major adverse events were compared according to the type of revascularisation. RESULTS: Overall, 793 patients fulfilled the eligibility criteria, from whom 236 propensity score matched pairs were analysed. The mean follow up was 52 months. The 236 bypass procedures included 190 autogenous bypass grafts (80.5%), 151 (64.0%) of which were infrapopliteal. Among the 236 EVT procedures, the target lesion was the femoropopliteal segment in 81 patients (34.3%), the femoropopliteal and infrapopliteal segments in 101 patients (42.8%), and the infrapopliteal segment in 54 patients (22.9%). AFS was significantly better in the bypass group at five years (60.5 ± 3.6%) compared with the EVT group (35.3 ± 3.6%) (p < .001). Major amputation occurred in 61 patients (25.8%) in the bypass group and 85 patients (36.0%) in the EVT group (HR 0.66, 95% CI 0.47 - 0.92; p = .014). The probability of healing was significantly better in the bypass group at six months compared with the EVT group (p = .003). The median length of stay was shorter for the EVT group (4 days) than for the bypass group (8 days) (p = .001). Urgent re-intervention and re-admission rates were high and did not differ significantly between the groups. CONCLUSION: This study has shown that lower limb bypass surgery offered a significantly higher probability of AFS and wound healing compared with EVT in patients with CLTI.

RESUMO

OBJECTIVE: To evaluate the results of carotid endarterectomy (CEA) in patients with a concomitant asymptomatic intracranial aneurysm discovered at preoperative diagnostic imaging. METHODS: From January 2000 to December 2020, 75 consecutive patients admitted for surgical treatment of asymptomatic more than 70% (North American Symptomatic Carotid Endarterectomy Trial) carotid artery stenosis presented at preoperative computed tomography angiography (CTA) with a concomitant, unruptured intracranial aneurysm (UIA). Aneurysm diameter was 5 mm or less in 25 patients (group A), from 6 to 9 mm in 38 patients (group B), and 10 or more mm in 12 patients (group C). Sixty UIAs (80%) were treated before performing CEA, 10 in group A (40%), 38 (100%) in group B, and 12 (100%) in group C. Twenty-five UIAs (42%) were subjected to surgical clipping and 35 (58%) to coiling. The mean time intervals were 48 days (range, 20-55 days) between clipping and CEA, and 8 days (range, 4 -13 days) between coiling and CEA. CEA was standard and performed through eversion of the internal carotid artery in 36 patients (48%) and through longitudinal arteriotomy with systematic patch closure in 39 patients (52%). The primary end points of the study were mortality and morbidity related to each of the two treatments, including any complication occurring during the time interval between the two procedures or within 30 days after the last procedure. Secondary end points were mid-term survival and freedom from ischemic or hemorrhagic stroke and carotid restenosis. RESULTS: One patient died during the 30 days after the clipping of a 11-mm diameter UIA of the basilar artery. No other death or complication was observed after CEA and treatment of the UIA, or during the time interval between the two procedures. During a median follow-up of 26 months (interquartile range, 18-30 months), no late stroke and no carotid restenosis were observed. At 22, 27, 29 and 31 months after CEA, four patients in group A underwent surgical clipping of an enlarging intracranial aneurysm that had not been treated initially owing to its small diameter. The cumulative survival rate at 30 months by Kaplan-Meier plots was 83 ± 5%. CONCLUSIONS: Concomitant asymptomatic carotid artery stenosis and UIA is a rare entity. Our study suggests that in this setting, prior treatment of the UIA followed by CEA is safe.

RESUMO

BACKGROUND: Reducing fluoroscopy times and iodine contrast administration during endovascular repair (EVAR) of infrarenal aortic aneurysms remains a challenge. The purpose of this study is to evaluate the preliminary results of a fully ultrasound-assisted EVAR without iodine contrast administration. METHODS: Twenty-seven consecutive patients underwent an elective intravascular ultrasound (IVUS)-assisted EVAR with final contrast-enhanced ultrasound (CEUS) control of correct aneurysm exclusion. In no case intraprocedural injection of iodine contrast medium was performed. The primary study's end points were the overall duration of the procedure, duration of fluoroscopy, cumulative radiation dose, the length of intraoperative CEUS control, and the comparison of findings between intraoperative CEUS and computed tomography (CT) scan at 1 month. RESULTS: Mean duration of the procedure was 130 ± 35 min. Overall duration of fluoroscopy was 22 ± 18 min. Mean radiation dose was 66 mGy (range 24-82). The mean length of CEUS final control was 8 ± 2 min. No type I or type III endoleak was detected either at CEUS or at angio-CT scan at 1 month from EVAR. CEUS revealed a type II endoleak in 6 patients (22%), compared to 9 type II endoleaks (33%) detected at angio-CT scan 1 month after the procedure (P = 0.5). CONCLUSIONS: Fully ultrasound (IVUS and CEUS)-assisted EVAR is safe, feasible, and reliable, completely eliminating the need for iodine contrast medium and reducing the radiation exposure for both patients and surgeons.

RESUMO

OBJECTIVE: True aneurysms of the peri-pancreatic arcade (PDAA) have been attributed to increased collateral flow related to coeliac axis (CA) occlusion by a median arcuate ligament (MAL). Although PDAA exclusion is currently recommended, simultaneous CA release and the technique to be used are debated. The aim of this retrospective multicentre study was to compare the results of open surgical repair of true non-ruptured PDAA with release or CA bypass (group A) vs. coil embolisation of PDAA and CA stenting or laparoscopic release (group B). METHODS: From January 1994 to February 2019, 57 consecutive patients (group A: 31 patients; group B: 26 patients), including 35 (61%) men (mean age 56 ± 11 years), were treated at three centres. Twenty-six patients (46%) presented with non-specific abdominal pain: 15 (48%) in group A and 11 (42%) in group B (p = .80). RESULTS: No patient died during the post-operative period. At 30 days, all PDAAs following open repair and embolisation had been treated successfully. In group A, all CAs treated by MAL release or bypass were patent. In group B, 2/12 CA stentings failed at < 48 hours, and all MAL released by laparoscopy were successful. Median length of hospital stay was significantly greater in group A than in group B (5 vs. 3 days; p = .001). In group A, all PDAAs remained excluded. In group B, three PDAA recanalisations following embolisation were treated successfully (two redo embolisations and one open surgical resection). At six years, Kaplan-Meier estimates of freedom for PDAA recanalisation were 100% in group A, and 88% ± 6% in group B (p = .082). No PDAA ruptured during follow up. In group A, all 37 CAs treated by MAL release were patent, and one aortohepatic bypass occluded. In group B, five CAs occluded: four after stenting and the other after laparoscopic MAL release with two redo stenting and three aortohepatic bypasses. Estimates of freedom from CA restenosis/occlusion were 95% ± 3% for MAL release or visceral bypass, and 60% ± 9% for CA stenting (p = .001). Two late restenoses following CA stenting were associated with PDAA recanalisation. CONCLUSION: Current data suggest that open and endovascular treatment of PDAA can be performed with excellent post-operative results in both groups. However, PDAA embolisation was associated with few midterm recanalisations and CA stenting with a significant number of early and midterm failures.

RESUMO

BACKGROUND: Penetrating aortic ulcer (PAU) is an atherosclerotic lesion penetrating the elastic lamina and extending into the media of the aorta. It may evolve into intramural hematoma, focal dissection, pseudoaneurysm, and eventually rupture. The purpose of this study was to evaluate the effectiveness of a totally intravascular ultrasound (IVUS)-assisted endovascular exclusion of PAU. METHODS: Thirteen consecutive patients (median age 66 years) underwent IVUS-assisted endovascular exclusion of PAU. The primary end points were fluoroscopy time, radiation dose, and occurrence of type I primary endoleak. Secondary end points were postoperative mortality and morbidity, arterial access complications, postoperative length of stay in the hospital, and occurrence of type II endoleaks. RESULTS: The median fluoroscopy time was 4 min (4-5). The median radiation dose was 4.2 mGy (3.9-4.5). A proximal and distal landing zone of at least 2 cm could be obtained in all the patients. No patient presented a type I endoleak. No postoperative mortality, no morbidity, or arterial access complication was observed. The median length of postoperative stay in the hospital was 2 days (2-3). The median length of follow-up was 25 months (9.2-38.7). One late type II endoleak was observed (7.7%), because of reflux from the intercostal arteries, without the need for additional treatment. CONCLUSIONS: IVUS-assisted endovascular treatment of PAU allows durable exclusion of PAU with a short fluoroscopy time and no need for injection of contrast media. Further series are needed to confirm the results of this preliminary study.

RESUMO

PURPOSE: The double-staple technique, performed as either the standard procedure or after eversion of the rectal stump, is a well-established method of performing low colorectal anastomoses following the resection of rectal cancer. Eversion of the tumor-bearing ano-rectal stump was proposed to allow the linear stapler to be fired at a safe distance of clearance from the tumor. We conducted this study to compare the results of the standard versus the eversion-modified double-staple technique. METHODS: The subjects of this retrospective study were 753 consecutive patients who underwent low stapled colorectal anastomosis after resection of rectal cancer. The patients were divided into two groups according to the method of anastomosis used: Group A comprised 165 patients (22%) treated with the modified eversion technique and group B comprised 588 patients (78%) treated with the standard technique. The primary endpoints of the study were postoperative mortality, surgery-related morbidity, the number of sampled lymph nodes in the mesorectum, and late disease-related survival. RESULTS: Postoperative mortality was 1.2% in group A and 1.7% in group B (p = 0.66). Postoperative morbidity was 12% in group A and 11% in group B (p = 0.75). The mean number of sampled lymph nodes in the mesorectum was 23 (range 17-27) in group A and 24 (range 19-29) in group B (p = 0.06). The 5-year disease-related survival was 73% in group A and 74% in group B (p = 0.75). CONCLUSION: The standard and eversion-modified double-staple techniques yield comparable results.

RESUMO

OBJECTIVE: To compare the results of polytetrafluoroethylene (PTFE) and great saphenous vein (GSV) bypass after resection of a degenerative aneurysm of the carotid artery. METHODS: From January 1994 to November 2017, 37 patients (27 men) with a mean age of 58 years (range, 39-82 years) with a degenerative aneurysm of the carotid artery (median diameter, 28 mm; range, 19-42 mm), underwent resection of the aneurysm followed by a bypass with either a GSV (n = 10) or a PTFE prosthesis (n = 27). Although 31 patients were asymptomatic, 6 patients were symptomatic: transient ischemic attack (n = 4), minor stroke (n = 1), and compression of the hypoglossal nerve (n = 1). The preoperative workup included duplex ultrasound examination of the arteries to the head, and angiography or computed tomography angiography. All patients were operated under general anesthesia and six were intubated through the nose. Sixteen patients were monitored through transcutaneous oximetry. No shunt was used in this series. In 10 patients receiving a PTFE graft, the external carotid artery was implanted in the prosthesis. Mean follow-up was 16.9 ± 2 years (95% confidence interval, 14.5-19.3 years). Primary end points were the 30-day combined stroke/death rate, graft infection, late graft patency, and late stroke-free survival. Secondary end points were cranial nerve injury and length of postoperative hospital stay. RESULTS: Postoperative mortality was nil in both groups. One postoperative stroke was observed in the PTFE group, whereas none occurred in the GSV group (P = .84). No graft infection was observed in either group. At 10 years, survival in the GSV group was 80 ± 12%, and survival in the PTFE group was 76 ± 8% (log-rank [Mantel-Cox], P = .85). In the GSV group, graft patency at 7 and 10 years was 85 ± 13%. In the PTFE group B, graft patency was 100% (log-rank [Mantel-Cox], P = .12). No late stroke was observed. Two transient cranial nerve injuries were observed in the GSV group (20%) and two in the PTFE group (8%) (P = .97). Length of hospital stay was comparable in both groups (GSV group, 6 days; PTFE group, 5 days; P = .12). CONCLUSIONS: This study suggests that, after resection of a degenerative aneurysm of the carotid artery, bypass with a PTFE prosthesis gives comparable results to those obtained with the GSV. We recommend sparing the GSV and instead using a PTFE prosthesis in patients with a degenerative aneurysm of the carotid artery.

RESUMO

BACKGROUND: The aim of this study was to compare intravascular ultrasound (IVUS) assistance for endovascular aortic aneurysm repair (EVAR) to standard assistance by angiography. METHODS: From June 2015 to June 2017, 173 consecutive patients underwent EVAR. In this group, 69 procedures were IVUS-assisted with X-ray exposure limited to completion angiography for safety purposes because an IVUS probe does not yet incorporate a duplex probe (group A), and 104 were angiography-assisted procedures (group B). All IVUS-assisted procedures were performed by vascular surgeons with basic duplex ultrasound (DUS) training. The primary study endpoints were mean radiation dose, duration of fluoroscopy, amount of contrast media administered, procedure-related outcomes, and renal clearance expressed as the glomerular filtration rate (GFR) before and after the procedure. Secondary endpoints were operative mortality, morbidity, and arterial access complications. RESULTS: Mean duration of fluoroscopy time was significantly lower for IVUS-assisted procedures (24 ± 15 min vs. 40 ± 30 min for angiography-assisted procedures, P < 0.01). Moreover, mean radiation dose (Air KERMA) was significantly lower in IVUS-assisted procedures (76m Gy [44-102] vs. 131 mGy [58-494]), P < 0.01. IVUS-assisted procedures required fewer contrast media than standard angiography-assisted procedures (60 ± 20 mL vs. 120 ± 40 mL, P < 0.01). The mean duration of the procedure was comparable in the two groups (120 ± 30 min vs. 140 ± 30 min, P = 0.07). No difference in renal clearance before and after the procedure was observed in either of the two groups (99.0 ± 4/97.8 ± 2 mL/min in group A and 98.0 ± 3/97.6 ± 5 mL/min in group B) (P = 0.28). The mean length of follow-up was nine months (6-30 months). No postoperative mortality, morbidity, or arterial access complications occurred. No type 1 endoleak was observed. Early type II endoleaks were observed in 21 patients (11%), 12 in the angiography-assisted group (11%) and nine in the IVUS-assisted group (12%). They were not associated with sac enlargement ≥5 mm diameter and therefore did not require any additional treatment. CONCLUSIONS: Compared with standard angiography-assisted EVAR, IVUS significantly reduces renal load with contrast media, fluoroscopy time, and radiation dose while preserving endograft deployment efficiency. Confirmation from a large prospective study with improved IVUS probes will be required before IVUS-assisted EVAR alone can become standard practice.

RESUMO

BACKGROUND: No consensus exists on the optimal strategy for treatment of abdominal aortic aneurysm (AAA) associated with colorectal cancer (CRC). The purpose of this study was to evaluate the results of endovascular treatment of AAA with simultaneous resection of CRC. METHODS: Twenty-two consecutive patients presenting with AAA associated with a CRC were treated by endovascular AAA exclusion and simultaneous CRC resection. Median diameter of the aneurysm was 6.5 cm (range, 4.8-8 cm). Two patients (9%) had grade I cancer, 5 patients (23%) grade II, 13 patients (59%) grade III, and 2 patients (9%) grade IV. The 2 surgical procedures were performed under the same general anesthesia. Aneurysm exclusion was achieved using an infrarenal aorto-bi-iliac endoprosthesis (13 patients) and using an aorto-bi-iliac endoprosthesis with suprarenal fixation (9 patients), with 1 patient receiving bilateral renal chimney stent implantation. In all cases, vascularization of the hypogastric arteries was preserved. After AAA exclusion, colic resection was carried out by laparotomy with right colectomy (7 patients) and anterior rectocolic resection (15 patients). In all patients, AAA exclusion was controlled by a computed tomographic angioscan (CTA) at 1 month and duplex ultrasound every 6 months, and at some later stage, it was through inclusion of CTA as part of oncology surveillance. The mean duration of follow-up was 42 months (10-120 months). The primary endpoint was composite and regrouped any death occurring during the first 30 days after procedures, any type I endoleak, any aortic reintervention, and any AAA-related mortality. RESULTS: No patient died during the first 30 postoperative days, and no patient was lost to follow-up. No aortic endoprosthesis infection and no type I endoleak were observed. Five endoleaks arising from the lumbar arteries (n = 4) or from the inferior mesenteric artery (n = 1) were identified. As they were not associated with an increase of the AAA diameter >5 mm, they were not treated. 1 colic anastomotic leak and 2 incisional abscesses were successfully cured by local care only. Nine patients (41%) died of cancer evolution during the follow-up period. CONCLUSIONS: In this series, treatment of AAA and CRC during the same operative session yields results comparable to those observed when surgery is performed in 2 distinct operative sessions. Synchronous treatment reduced waiting time of colic resection. It may also shorten total hospitalization duration, although this last hypothesis is not supported by comparison with a control group.

RESUMO

BACKGROUND: When the common femoral artery is not accessible for infrainguinal bypass grafting, the profunda femoris artery (PFA) can be a valuable alternative inflow source for distal arterial revascularization. The purpose of this retrospective study was to evaluate the results of infrageniculate bypass grafting via the PFA as inflow source for critical limb ischemia. METHODS: Between 1994 and 2016, 68 patients, 51 men of a mean age of 74 years, underwent an infrageniculate arterial bypass grafting for critical limb ischemia, using the PFA as inflow site. PFA was exposed at the Scarpa's triangle in 38 patients (56%) and at its medio-crural segment in 30 patients (44%). The distal anastomosis was performed on the infragenicular popliteal artery in 33 patients (48%), the peroneal artery in 14 patients (20%), the tibioperoneal trunk in 8 patients (12%), the posterior tibial artery in 8 patients (12%), and the dorsalis pedis artery in 5 patients (8%). The graft material consisted of a reversed great saphenous vein (GSV) in 62 patients (91%) and a 6-mm polytetrafluoroethylene graft in 6 patients (9%). The median duration of follow-up was 51 months (range, 6-72 months). As main results, postoperative mortality and morbidity, overall late patients' survival, primary grafts' patency, and limb salvage rate were considered. RESULTS: Operative mortality and morbidity were 3% and 4%, respectively. Overall patients' survival, primary patency and limb salvage rate, at 36 and 60 months were, respectively, 62% and 53%, 66% and 59%, and 92% and 77%. CONCLUSIONS: The PFA, both exposed at the Scarpa's triangle and at mid-thigh, is an excellent inflow source for infrageniculate revascularizations. It should remain an important part of the technical armamentarium of vascular surgeons, even in the endovascular era.

RESUMO

OBJECTIVE: The objective of this study was to evaluate the results of prosthetic carotid bypass (PCB) with polytetrafluoroethylene (PTFE) grafts as an alternative to carotid endarterectomy (CEA) in treatment of restenosis after CEA or carotid artery stenting (CAS). METHODS: From January 2000 to December 2014, 66 patients (57 men and 9 women; mean age, 71 years) presenting with recurrent carotid artery stenosis ≥70% (North American Symptomatic Carotid Endarterectomy Trial [NASCET] criteria) were enrolled in a prospective study in three centers. The study was approved by an Institutional Review Board. Informed consent was obtained from all patients. During the same period, a total of 4321 CEAs were completed in the three centers. In these 66 patients, the primary treatment of the initial carotid artery stenosis was CEA in 57 patients (86%) and CAS in nine patients (14%). The median delay between primary and redo revascularization was 32 months. Carotid restenosis was symptomatic in 38 patients (58%) with transient ischemic attack (n = 20) or stroke (n = 18). In this series, all patients received statins; 28 patients (42%) received dual antiplatelet therapy, and 38 patients (58%) received single antiplatelet therapy. All PCBs were performed under general anesthesia. No shunt was used in this series. Nasal intubation to improve distal control of the internal carotid artery was performed in 33 patients (50%), including those with intrastent restenosis. A PTFE graft of 6 or 7 mm in diameter was used in 6 and 60 patients, respectively. Distal anastomosis was end to end in 22 patients and end to side with a clip distal to the atherosclerotic lesions in 44 patients. Completion angiography was performed in all cases. The patients were discharged under statin and antiplatelet treatment. After discharge, all of the patients underwent clinical and Doppler ultrasound follow-up every 6 months. Median length of follow-up was 5 years. RESULTS: No patient died, sustained a stroke, or presented with a cervical hematoma during the postoperative period. One transient facial nerve palsy and two transient recurrent nerve palsies occurred. Two late strokes in relation to two PCB occlusions occurred at 2 years and 4 years; no other graft stenosis or infection was observed. At 5 years, overall actuarial survival was 81% ± 7%, and the actuarial stroke-free rate was 93% ± 2%. There were no fatal strokes. CONCLUSIONS: PCB with PTFE grafts is a safe and durable alternative to CEA in patients with carotid restenosis after CEA or CAS in situations in which CEA is deemed either hazardous or inadvisable.

RESUMO

BACKGROUND: The purpose of this study was to evaluate the risk of bleeding and other postoperative complications of carotid endarterectomy (CEA) in patients receiving dual antiplatelet therapy (DAPT). METHODS: From January 2005 to December 2015, 188 consecutive patients undergoing CEA and receiving DAPT (aspirin 100 mg + clopidogrel 75 mg) were enrolled in a prospective study. All of them underwent coronary artery stenting with drug-eluting stents during the 6 months preceding CEA. In the entire series, DAPT was continued until the evening before CEA and resumed on the evening of the operation. All patients received intraoperative heparinization (5,000 IU before carotid clamping), which was reversed in 5 patients. In addition, all of them were given 2,000 units of enoxaparin every 12 hr after the operation, beginning 6 hr after completion of the operation, and until discharge. All the patients presented with carotid artery stenosis >70% (North American Symptomatic Carotid Endarterectomy Trial [NASCET] criteria), which was symptomatic in 42 patients (transient ischemic attack, n = 32; minor stroke, n = 10) and asymptomatic in 146. The CEA technique was standard, with prosthetic patch closure in 109 cases (58%) and eversion in 79 (42%). The primary endpoints of the study were occurrence of a postoperative cervical hematoma requiring surgical hemostasis and occurrence of cranial nerve injuries. The secondary endpoint was the combined rate of postoperative mortality, stroke, and myocardial ischemia. RESULTS: No postoperative cervical hematoma requiring surgical evacuation occurred in this series. One hypoglossal nerve palsy, regressive within 2 weeks, was observed. Postoperative mortality and neurologic and cardiac morbidity were nil. CONCLUSIONS: CEA under DAPT yields results comparable with those obtained in patients receiving a single antiplatelet treatment. No hemorrhagic complications were observed in this prospective series.

RESUMO

OBJECTIVE: The management of patients with recurrent neck cancer invading the carotid artery is controversial. The purpose of this study was to evaluate overall survival rate, primary patency of vascular reconstructions, and quality-adjusted life-years (QALYs) after en bloc resection of the carotid artery and tumor with in-line polytetrafluoroethylene (PTFE) carotid grafting, followed by radiotherapy. METHODS: From 2000 to 2014, 31 consecutive patients with recurrent neck cancer invading the carotid artery underwent en bloc resection and simultaneous carotid artery reconstruction with a PTFE graft, which was associated in 18 cases with a myocutaneous flap. The primary tumor was a squamous cell carcinoma of the larynx in 17 patients and of the hypopharynx in 7, an undifferentiated carcinoma of unknown origin in 4, and an anaplastic carcinoma of the thyroid in 3. All of the patients underwent postoperative radiotherapy (50-70 Gy), and 10 of them also underwent chemotherapy (doxorubicin and cisplatin). RESULTS: None of the patients died or sustained a stroke during the first 30 days after the index procedure. Postoperative morbidity consisted of 6 transitory dysphagias, 3 vocal cord palsies, 2 wound dehiscences, 1 transitory mandibular claudication, and 1 partial myocutaneous flap necrosis. No graft infection occurred during follow-up. Fifteen patients (48%) died from metastatic cancer during a mean follow-up of 45.4 months (range, 8-175 months). None of the patients showed evidence of local recurrence, stroke, or thrombosis of the carotid reconstruction. The 5-year survival rate was 49 ± 10%. The overall number of QALYs was 3.12 (95% confidence interval, 1.87-4.37) with a significant difference between patients without metastasis at the time of redo surgery (n = 26; QALYs, 3.74) and those with metastasis (n = 5; QALYs, 0.56; P = .005). QALYs were also significantly improved in patients with cancer of the larynx (n = 17; QALYs, 4.69) compared to patients presenting with other types of tumors (n = 14; QALYs, 1.29; P = .032). CONCLUSIONS: Aggressive en bloc resection of recurrent neck cancer with PTFE grafting can be curative in patients without metastases at the time of redo surgery. In this subset of patients, extensive neck surgery with carotid artery replacement can lead to excellent local control of the disease with improved quality of survival.

RESUMO

BACKGROUND: The purpose of this study was to evaluate the strategy for treatment of patients presenting with asymptomatic diverticular disease of the large bowel associated with an asymptomatic aortoiliac aneurysmal (AAA) disease. METHODS: Sixty-nine patients were included in this retrospective study. The patients were divided into 5 groups according to the type and sequence of the surgical treatment: 32 patients (47%) underwent colectomy followed by a staged open AAA repair (group A); 10 patients (14%) were treated with open AAA repair followed by a staged colectomy (group B); 13 patients (18%) received endovascular aneurysm repair (EVAR) followed by a staged bowel resection (group C); 8 patients (12%) had a bowel resection followed by staged EVAR (group D); and 6 patients (9%) underwent simultaneous open AAA repair and bowel resection (group E). Primary end points were mortality and complications after any of the procedures. Secondary end point was the time interval between the staged procedures. RESULTS: The cumulative death rate for delayed treatment of AAA was 6.5% and 0% for delayed treatment of diverticular disease [P=0.22]. The mean time interval between the staged procedures was 11 days for EVAR/colon resection (group C and group D) and 73 days for open AAA repair/colon resection (group A and group B; P<0.01). CONCLUSIONS: EVAR allows a significant reduction in the time required between AAA repair and colon resection, but no definite rule can be established regarding the sequence of staged procedures. Combined procedures should be reserved for selected cases.

RESUMO

Background/Objectives: Giant splenic artery aneurysms (SAAs) and pseudoaneurysms (SAPs) represent rare conditions, characterized by a diameter greater than or equal to 5 cm. The risk of rupture is increased compared to common SAAs and SAPs, necessitating urgent treatments to prevent it. Methods: This systematic review was conducted through a comprehensive search involving the PubMed, Google Scholar, and Scopus databases. A total of 82 patients and 65 articles were included in the analysis. For each patient, we investigated age, sex, symptoms, comorbidities, the presence of a true or a false aneurysm, the dimensional criteria used to define dilations as giant aneurysms or pseudoaneurysms, the dimension of the two greatest diameters, imaging studies, surgical treatment, post-operative length of stay (LOS), and post-operative follow-up. Results: The results revealed a similar incidence in both genders (43 males vs. 39 females) with a median age of 55.79 years. The most frequently described symptom was pain (59.76%). Thirteen cases were false aneurysms and 69 were true aneurysms. The mean greatest diameter was 9.90 cm. The CT scan was the most utilized imaging study (80.49%). Open, endovascular, and hybrid surgery were performed in 47, 26, and 9 patients, respectively, with complication rates of 14.89%, 23.08%, and 22.22% occurring for each treatment. The post-operative LOS was 12.29 days, 2.36 days, and 5 days, respectively. The median follow-up was 17.28 months overall. No recanalization was observed after endovascular procedures during the follow-up period. Conclusions: The dimensional criterion to define SAAs and SAPs as giant was most frequently that at least one diameter was ≥ 5 cm. The CT scan was the most frequently utilized radiological study to diagnose giant SAAs and SAPs. Finally, endovascular procedures, open surgeries, and hybrid treatments presented similar post-operative complication rates. The post-operative LOS was lower for the endovascular group, and the follow-up period did not show aneurysm recanalization in any patients.

RESUMO

Late type II endoleaks (T2ELs) arising from the internal iliac artery (IIA) may present during follow-up after endovascular aortic repair (EVAR) of aortoiliac aneurysm and may warrant embolization if enlargement of the aneurysmal sac is demonstrated. When coverage of the IIA ostium has been made due to extensive iliac disease, access options can be challenging. Different treatment options have been reported over recent years, and a careful selection of the best one must be made based on the characteristics of each case. The present study reports a simple and reproducible sheathless percutaneous superior gluteal artery (SGA) access and provides a discussion based on a review of the existing literature on this topic.

RESUMO

Background: Cardiovascular and renal diseases represent a major determinant for the morbidity and mortality associated with obesity and type 2 diabetes mellitus (T2DM). Bariatric surgery is considered one of the few treatments with the potential to reverse cardiovascular, renal and metabolic disease. Methods: Prospective study of patients undergoing sleeve gastrectomy collecting pre- and post-surgery creatinine, eGFR, glucose, insulin, total, LDL/HDL cholesterol, triglycerides, parathyroid hormone, vitamin D3, C- Reactive Protein (CRP), blood count, weight, body mass index (BMI), bilateral carotid intima media thickness (IMT), flow-mediated dilation (FMD) and epicardial adipose tissue (EAT). Measurements were compared at 1 year follow up. Results: 24 patients were included in the study. Cardiovascular parameters, as HDL-cholesterol (p = 0.002), IMT (p = 0.003), EAT (p < 0.001) and FMD (p = 0.001) showed significant improvement after surgery. Secondary renal outcomes including Vitamin D3 (p < 0.0001), Calcium (p = 0.006), RBCs (p = 0.007), HCO3- (p = 0.05) also ameliorated as well as BMI (p < 0.001). Conclusions: Sleeve gastrectomy has a positive impact on cardiovascular, renal, and metabolic parameters in patients with morbid obesity, suggesting it may halt the progression of these diseases even in the preclinical stage. Further research is needed to explore the long-term effects underlying these improvements.

RESUMO

Background: Performing percutaneous coronary intervention (PCI) and endovascular aneurysm repair (EVAR) at the same time represents a groundbreaking development in the multidisciplinary treatment of cardiovascular disease. This combined PCI-EVAR approach bridges a critical gap by offering treatment for patients who have both coronary artery disease and aortic aneurysms. This innovative strategy exemplifies the evolving landscape of cardiovascular care, providing a new solution for complex clinical situations that previously required separate procedures. Methods: Six patients with critical coronary artery lesions and asymptomatic infrarenal aortic aneurysms (AAAs) ≥ 6 cm diameter, as well as one patient with critical coronary artery lesions and endoleak type 1A with aneurysms ≥ 6 cm, underwent simultaneous coronary artery revascularization through percutaneous intervention (PCI) and endovascular aneurysm repair (EVAR). The occurrence of any intraoperative or postoperative complication was considered to be the primary endpoint of the study, including the abortion or failure of either PCI or EVAR, bleeding requiring a conversion to open surgical procedures, the failure of local anesthesia, postoperative myocardial or lower limb ischemia, and a postoperative serum creatinine level of >125 mmol/L or of >180 mmol/L in patients affected by chronic renal failure. The overall length of the procedure, X-ray exposure, the quantity of iodine contrast medium administered, and the length of recovery were considered to be secondary endpoints. Results: Postoperative complications included two episodes of acute renal failure in the two patients already affected by chronic renal failure, which were easily resolved with adequate daily hydration and the elimination of nephrotoxic drugs. In no cases did cardiac ischemia or lower limb ischemia occur. The average procedure duration was 198 min (range: 180-240 min), the average fluoroscopy duration was 41.7 min (range: 35-50 min), the average amount of iodinated contrast medium was 34.8 mL (range: 30-40 mL), and the mean length of hospitalization was 2.7 days (range: 2-5 days). Conclusions: In selected patients, this surgical approach has demonstrated safety, reduced hospitalization times, minimized risks associated with complications from the untreated condition if procedures were performed at different times, and facilitated the effective management of intraoperative complications due to the presence of a multidisciplinary team. However, the limited number of patients necessitates further research.

RESUMO

A variety of completion imaging methods can be used during carotid endarterectomy to recognize technical errors or intrinsic abnormalities such as mural thrombus or platelet aggregation, but none of these methods has achieved wide acceptance, and their ability to improve the outcome of the operation remains a matter of controversy. It is unclear if completion imaging is routinely necessary and which abnormalities require re-exploration. Proponents of routine completion imaging argue that identification of these abnormalities will allow their immediate correction and avoid a perioperative stroke. However, much of the evidence in favor of this argument is incidental, and many experienced vascular surgeons who perform carotid endarterectomy do not use any completion imaging technique and report equally good outcomes using a careful surgical protocol. Furthermore, certain postoperative strokes, including intracerebral hemorrhage and hyperperfusion syndrome, are unrelated to the surgical technique and cannot be prevented by completion imaging. This controversial subject is now open to discussion, and our debaters have been given the task to clarify the evidence to justify their preferred option for completion imaging during carotid endarterectomy.
