Symptomatic superficial femoral artery pseudoaneurysm due to late stent fracture
No full textLate formation of pseudoaneurysm related to stent fracture is rarely described in the literature. We describe a case of spontaneous 8-cm femoral superficial artery pseudoaneurysm rupture that had developed from fracture of a stent implanted 3 years previously. Surgical repair was performed with fractured stent removal and reverse saphenous vein bypass
Contained rupture of an aortic arch aneurysm in a patient with syphilitic aortitis. A case report
Full text linkSyphilitic aortitis is a rare complication of tertiary syphilis, which can lead to aortic aneurysm formation, aortic valvular insufficiency, and ostial coronary stenosis. Syphilis has re-emerged worldwide over recent decades and vascular surgeons should be aware of its cardiovascular manifestations. Atypical clinical presentation, such as hemoptysis and a computed tomography angiography pattern of a thicker aneurysmal wall with ulcer-like aneurysm projections, should raise suspicion of syphilitic aortic aneurysm. An early diagnosis and appropriate surgical and medical therapies significantly contribute to successful treatment and favorable prognosis. Herein is reported the case of an 82-year-old male patient, positive for syphilis infection, with impending aortic arch aneurysm rupture treated with a hybrid arch repair. After 7 months, the patient was brought to the emergency room in cardiac arrest. Unsuccessful cardiopulmonary resuscitation maneuvers were performed, and an autopsy showed cardiac tamponade due to rupture of the ascending aorta

Self-occluding Candy-Plug: Implantation Technique to Obtain False Lumen Thrombosis in Chronic Aortic Dissections
Full text linkPurpose: To describe the implantation steps of the latest generation of candy-plug device (third CP generation [CP III]) and to illustrate its possible pitfalls by discussing a case in whom this device was employed to occlude the false lumen (FL) of a chronic type B aortic dissection. Technique: A 69 year-old male patient who underwent a frozen elephant trunk arch repair due to residual type A aortic dissection developed a FL aneurysmal degeneration limited to the descending thoracic aorta. Two thoracic stent-grafts were deployed into the true lumen up to the celiac trunk origin. Then, the FL was occluded with a self-occluding CP III device (Cook Medical, Bloomington, Indiana), placed at the same level as the distal thoracic stent-graft. The distal un-stented sleeve was pushed upward to allow immediate occlusion of its central lumen, avoiding interference with reno-visceral arteries arising from the FL. Both intraoperative transesophageal echocardiography and follow-up computed tomographic angiography scan demonstrated complete FL thrombosis. Conclusion: The introduction of CP III with its self-occluding mechanism helped to shorten and standardize the procedure. However, adjunctive steps may be needed to immediately obtain FL occlusion and avoid hampering the perfusion of vessels arising from the FL
Early Limb Reperfusion Using Routinely Preloaded Fenestrated Stent-graft Designs for Complex Endovascular Aortic Procedures
No full textIntroduction: To evaluate the outcomes of the preloaded stent-graft design (PLD) in the routine treatment of pararenal and thoraco-abdominal aneurysms compared to the standard design (SND). Methods: Patients treated by fenestrated/branched endovascular aneurysm repair from 2013 were collected. Since 2017, PLD (23F delivery system) was implemented in our standard practice and the outcomes are reported. Primary outcome measurements were: technical success, 30-day adverse events, leg ischemia time, procedural time and radiation exposure. Secondary outcome measurements were: intraoperative urinary output, need of bicarbonate supplementation, postoperative biomarkers elevations and need for blood transfusions. A propensity 1:1 matching for graft design and aneurysm extent was performed with the SND (18F delivery system) cohort to highlight possible PLD advantages. Results: A PLD was employed in 32 non-consecutive patients with a technical and clinical success rate of 100% and 81% respectively: no mortality was recorded. The Society for Vascular Surgery grade ≥ 1 adverse event was observed in 10 cases (31%): five temporary paraparesis were observed. Seventeen PLD patients were matched. The procedural time was shorter in PLD group (266 vs. 390 min; p = 0.001) as well as fluoroscopy time (68 vs. 96 min; p = 0.019) and contrast media used (180 vs. 382 ml; p = 0.045). Contralateral limb ischemic time was significantly higher in SND group (0 vs. 70 min; p = 0.042). The need for blood transfusion and the postoperative peak of creatine phosphokinase was lower in PLD group (151 vs. 449 U/l; p < 0.001). Conclusions: Preloaded stent-graft design allows a uni-femoral approach in the majority of the interventions reducing procedural times and the ischemia on the contralateral leg, leading to possible benefits
Comparison of anatomic feasibility of three different multibranched off-the-shelf stent-grafts designed for thoracoabdominal aortic aneurysms
No full textObjective: We compared the theoretical anatomic feasibility of endovascular treatment of thoracoabdominal aortic aneurysms (TAAAs) with three off-the-shelf multibranched stent-grafts: t-Branch (Zenith t-Branch; Cook Medical, Bloomington, Ind), Gore Excluder thoracoabdominal branch endoprosthesis (TAMBE; W. L. Gore & Associates, Flagstaff, Ariz), and E-nside (E-nside multibranch stent graft system; Jotec GmbH, Hechingen, Germany). Methods: Computed tomography scans of patients with degenerative TAAAs treated from 2007 to 2019 were reviewed, and the anatomic feasibility of the multibranched stent-grafts was assessed according to the manufacturer's instructions for use. The anatomic factors determining the overall feasibility were divided into access feasibility, aortic feasibility, and visceral vessel feasibility. Results: Degenerative TAAAs in 268 patients were analyzed. The overall feasibility did not differ significantly (TAMBE, 33%; t-Branch, 39%; E-nside, 43%; P =.271). Access, aortic, and visceral vessel feasibility alone excluded 18% to 22%, 35% to 49% and 21% to 26% of the patients respectively. The only significant difference between the devices was in aortic feasibility (P =.005), which was more frequently limited by the proximal aortic neck diameter in the TAMBE cohort and the inner visceral aortic diameter in the t-Branch cohort. The overall treatment feasibility using any of the three devices would have been 58%. Conclusions: The new investigational off-the-shelf multibranched stent-grafts did not significantly improve the theoretical applicability in an extensive cohort of patients with TAAAs. Improvements are warranted to increase their overall feasibility
A Case of Covid-19 Patient with Acute Limb Ischemia and Heparin Resistance
No full textHeparin resistance is an uncommon phenomenon defined as the need for high-dose unfractionated heparin (UFH) of more than 35,000 IU/day to achieve the target activated partial-thromboplastin time ratio or the failure to achieve the desired activated clotting time after a full UFH dose. This rare phenomenon is being more commonly observed in Covid-19 patients in a hypercoagulable state. We describe a Covid-19 patient confirmed by reverse-transcriptase polymerase chain reaction assay, with acute limb ischemia, who developed heparin resistance. The patient was managed by the departments of vascular surgery, anesthesia and intensive care, and the Coagulation Service and Thrombosis Research from San Raffaele Scientific Institute, Milan, Italy
Early and mid-term outcomes of open popliteal artery aneurysm repair with prosthetic grafts
No full textObjective: The aim of the present study was to assess the early and mid-term outcomes of open surgical repair (OSR) for popliteal artery aneurysms (PAAs) with prosthetic grafts. Methods: The pre-, intra-, and postoperative data for all the patients who had undergone OSR for PAAs with prosthetic grafts at our Institution between January 2009 and July 2019 were included in a prospectively maintained database, which was retrospectively analyzed. Primary patency was defined as uninterrupted flow (<50% stenosis) in the graft with no additional procedures performed. Secondary patency was defined as the restoration of graft patency. Results: A total of 82 patients had undergone OSR for 104 PAAs (median age, 71 years; interquartile range [IQR], 67-78 years; 82 men) with prosthetic grafts. Of the 104 PAAs, 72 (68%) had been asymptomatic. The median diameter was 30 mm (IQR, 24-37 mm). A medial approach was used for 35 PAAs (34%) and a posterior approach for 69 (65%). The repairs consisted of aneurysmectomy or aneurysm ligation without removal with an interposition graft placed and end-to-end anastomoses. The median operative time was 120 minutes (IQR, 103-142 minutes). The estimated blood loss was 281 mL (IQR, 150-281 mL). Only one patient treated with a posterior approach sustained a permanent peroneal nerve lesion. A second patient also treated via the posterior approach had required surgical revision for bleeding on postoperative day 2. No temporary lesions were recorded. No early amputations were required, and no perioperative deaths occurred. The median length of stay was 3 days (IQR, 3-4 days). An expanded polytetrafluoroethylene graft was used in 92 cases (88%) and a Dacron graft in 12 cases (12%). An 8-mm graft was used in 64 cases (62%). The median follow-up was 34.6 months (IQR, 8.5-62.7 months). No related mortality occurred. Of the 104 PAAs, 19 had required reintervention, with primary and secondary patency of 78% and 88% at 3 years, respectively. The median interval to reintervention was 28.3 months. Conclusions: OSR of PAAs with prosthetic grafts is safe and feasible, with good mid-term results and satisfactory primary and secondary patency at 3 years
