查看更多>>摘要：? 2021Background: Prosthetic vascular graft infection (PVGI) in the distal thigh is a rare wound; thus, little is known about which muscle flaps are the most useful and cause less lower extremity morbidity in such cases. Moreover, very few reliable muscle flaps are available around the distal thigh. Case Report: We report the case of a 72-year-old woman suffering from a distal thigh wound with PVGI. The graft was successfully preserved after coverage with a free latissimus dorsi musculocutaneous (LDM) flap. Conclusions: The free LDM flap procedure is more challenging than local muscle flaps; however, a free LDM flap can be a feasible option for a distal thigh wound with PVGI with the advantage of the maintenance of walking capability by preserving the lower-limb muscles.

Case Report: A 78-years-old patient, previously treated for AAA with OR and reimplantation of inferior mesenteric artery (IMA), has presented with 9 cm type-III TAAA and underwent to a multi-stage endovascular procedure. Two thoracic endografts, t-Branch and a straight endograft by Cook Zenith platform were deployed. Renal and superior mesenteric arteries were cannulated and revascularized. Through the left axillary access, a 5F-vertebral catheter was delivered over a 0.035 inch guidewire to selectively catheterize IMA. A post-anastomotic stenosis was stented to advance the sheath and the parallel-graft (Viabahn 7 × 150 mm, Gore) into the artery. Thus, a bifurcated endograft was deployed inside the previous OR. According to the Sandwich-Technique, the stentgraft was deployed parallel and outside the bifurcated device, inside the straight one and 2 cm into the IMA and then reinforced by a bare-metal-stent (Protégé EverFlex? 7 × 120 mm, Medtronic). Finally, a kissing ballooning of iliac endografts and parallel-graft was performed. The procedure was completed five days later, by stenting the celiac trunk. Post-operative course was uneventful. The 36-months CTA showed the patency of the IMA with no complications. Conclusion: The combination of t-Branch and Sandwich-Technique for IMA could be employed to treat extended TAAA with previous OR and reimplanted IMA thus minimizing the risk of colonic and spinal cord ischemia.
查看更多>>摘要：? 2021Background: Celiac artery aneurysm (CAA) is an infrequent aneurysm of the celiac visceral branch and is potentially life-threatening, mainly due to the risk of rupture. CAA is often diagnosed following rupture and rarely diagnosed secondary to a primary manifestation; obstructive jaundice is extremely rare and poorly described. This clinical case report reports a combined endovascular and endoscopic noninvasive treatment. Methods: A 51-year old male was admitted to the emergency department at the Arcispedale Santa Maria Nuova in Reggio Emilia following several days of jaundice. The patient did not have any history of abdominal trauma, chronic pancreatitis, bile duct calculus or alcohol abuse. Cholestatic impairment was demonstrated by blood analyses and abdominal ultrasound revealed a large cephalo-pancreatic mass. Contrast-enhanced computed tomography (CT) showed a 40 mm CAA, causing a common bile duct (CBD) compression and dilatation of the hepatic bile ducts. After a multidisciplinary team consultation, a noninvasive, combined endovascular and endoscopic approach was programmed in a hybrid room. Results: Immediate results confirmed successful exclusion of the CAA, stent graft patency and the absence of endoleak with correct positioning of a plastic stent in the CBD. At 1 month, an abdominal CT-angiography (CTA) evidenced a type II endoleak, successfully treated with an endovascular secondary procedure and an asymptomatic, partial downward dislodgement of the plastic stent in the CBD was correct with the positioning of 2 plastic stents. At 3-months cholangiography showed no dilation of intraepatic biliary ducts. Conclusions: Symptomatic CAA with common bile duct compression could be amenable to a combined endovascular and endoscopic noninvasive treatment.
查看更多>>摘要：? 2021Introduction: Endovascular aneurysm repair (EVAR) has become a standard in the treatment of aneurysms. However, complications still occur. Endoleaks are the most common. Graft infection diagnosis might be challenging. Even uncommon, we describe a case of epithelioid angiosarcoma after EVAR. Case report: A 64-year-old male came to our emergency department with left lumbar and left thigh flexion pain, increasing since a month. Four years before, he had been treated for a left common iliac artery aneurysm extending to the aortic bifurcation by EVAR with a bifurcated unibody aortic (AFX Endologix) endograft. The year before the admission, he was treated twice by percutaneous angioplasty for a symptomatic mural thrombus of the left endograft limb. On admission, CT angiogram showed a recurrence of the aneurysm associated with elevated lab inflammatory markers. FDG-PET-CT showed an abnormal tracer uptake in the endograft limbs and in the left inguinal area. White blood cell scintigraphy did not show any sign of endograft infection. CT angiogram performed 2 months later showed an additional increase of the infrarenal aortic and left common iliac aneurysms. We removed the endograft. Histological analysis showed an epithelioid angiosarcoma. Patient died a few weeks later during chemotherapy. Conclusion: For patients that have undergone EVAR and have subsequently developed morphological changes of the aortic wall and aneurysmal sac, an aortic tumor should be considered. Imaging diagnosis was challenging for this rare case of epithelioid angiosarcoma.
查看更多>>摘要：? 2021Background: Isolated testicular pain is an unusual clinical presentation of symptomatic abdominal aortic aneurysms (AAA). We present two patients hemodynamically stable with an isolated acute testicular pain related to an AAA and a review of the published literature up to present. Methods: Two adult-old males with an acute isolated testicular pain presented to the emergency department. Although both cases had their symptoms for more than 24 hours and were hemodynamically stable, the misdiagnosis of a urological condition in one case and a delay of the intervention in the second resulted in a sudden drop of vital signs and the need of an urgent open surgery. Results: A bibliographic review of the 15 published cases is presented. Most cases occurred without a previous diagnosis of AAA. Aneurysms were characteristically very large (mean 10 cm). The initial diagnosis was frequently wrong, attributing the pain mostly to genito-urinary conditions. The testicular pain presented days and even weeks before rupture, which may offer a convenient window of hemodynamic stability for repair. Conclusions: Acute testicular pain in adult-old patients with aneurysm risk factors and specially with a first urological evaluation discarding a genitourinary disorder should alert clinicians to consider the diagnosis of a symptomatic abdominal aortic aneurysm. The early and accurate recognition of these cases may increase the survival.
查看更多>>摘要：? 2021Objective: Currently, no standard treatment has been established for the total lesion in patient with Marfan Syndrome (MFS). This case report aims to present a total aortic and branches repair with hybrid therapy in a young patient with MFS. Methods: Clinical data including imaging manifestation, surgical document, and follow-up results were retrospectively collected and presented. Results: A young patient with MFS underwent multi-stage endovascular aortic management and open surgical repair. On-the-table fenestration technique was applied to reconstruct the branches of the abdominal aorta. A bypass from superior mesenteric artery to celiac trunk was performed. A Bentall operation was conducted to repair his ascending aorta and aortic valves. Finally, in situ fenestration technique was adopted to recanalize the branches of aortic arch. The 18 month follow-up computed tomography angiography demonstrated patency of all the aorta branches. Conclusion: It may be feasible to perform the total aortic and branches repair with hybrid therapy in patients with MFS.
查看更多>>摘要：? 2021 The Author(s)Background: Loeys-Dietz Syndrome is a rare connective tissue disorder that is associated with arterial pathologies such as aortic dissections, tortuosity and aneurysms.We present a child with Loeys-Dietz Syndrome type 2 that received total aortic and bilateral subclavian artery replacement. Case Report: A 9-year old boy with Loeys-Dietz Syndrome type 2 and acute type B aortic dissection received an urgent complete thoracic and thoraco-abdominal aortic repair within three days. First, the ascending aorta and aortic root were replaced in a Tirone David and Frozen Elephant Trunk procedure. Then, the descending and supramesenteric aorta was replaced by a Dacron interposition graft with direct implantation of the celiac trunk. During the 15 months follow-up, the patient required three more surgical interventions for rapid expanding aneurysms of both subclavian arteries and the infrarenal aorta. No major adverse event nor secondary interventions occurred. Ultrasonographic and magnetic resonance imaging follow-up is continued at 6-months intervals. Conclusion: Children with Loeys-Dietz Syndrome may require extensive aortic repair for aortic dissection and show rapidly expanding aneurysms. Referral to a center with pediatric vascular expertise and long-term follow-up examinations are crucial.
查看更多>>摘要：? 2021Background: Thoracic endovascular aortic repair (TEVAR) is the preferred treatment for different aortic pathologies, because it has reduced mortality and morbidity rates. However, TEVAR is not feasible in all cases due to aortic angulations, the hemodynamics of the aortic arch and narrow or tortuous iliofemoral access. Therefore, different adjuvant techniques, such as iliac percutaneous transluminal angioplasty, iliathrough-and-through guidewires and external transapical guidewires have been previously reported. Herein we describe the Skewer Technique for successful TEVAR delivery, through a right-brachial-femoral through-and-through guidewire and advancement of the delivery system into the innominate artery. Methods: A 38-year-old male presented with a symptomatic 11.5cm thoracic aneurysm with involvement of the left-subclavian artery ostium. The patient underwent left carotid-subclavian bypass and a TEVAR. Due to the huge size of the aneurysm a left-brachial-right femoral artery through-and-through guidewire was established. However, the achievement of a stable position for the deployment of the stentgraft was not possible. Eventually, the exclusion of the aneurysm was done with a right brachio-femoral through-and-through wire, inserting the proximal part of the delivery system into the innominate artery. Conclusions: The use of adjuvant techniques such as a through-and-through right brachial-femoral guidewire with advancement of the endograft delivery system in the innominate artery (Skewer Technique) represents a useful alternative option in cases where the angulations of the aortic arch impede the deployment of the stent graft using conventional techniques.
查看更多>>摘要：? 2021Background: Vascular leiomyosarcoma is a rare type of malignant tumor which arises from the smooth muscle tissue of blood vessel walls; it involves veins five times more frequently than arteries. There are only a few cases published in the literature and consequently there is limited experience regarding treatment and prognosis. Methods: A 66-year-old woman presented with left lower limb swelling and a left inguinal mass. Imaging revealed a seven-by-five cm well-circumscribed oval inguinal mass that incorporated the common femoral artery including its bifurcation and compressed the common femoral vein. Other malignancies or metastatic disease were excluded. The patient underwent en bloc resection of the tumor, including the common femoral artery and its bifurcation and arterial reconstruction, using the inverted contralateral great saphenous vein, was carried out. Histopathological examination of the mass revealed moderately-differentiated leiomyosarcoma arising from the femoral artery wall without invasion of the intima. The postoperative course was uneventful. 12 months after the procedure the patient was in good clinical conditions and a contrast enhanced CT scan showed patency of the arterial reconstruction without local recurrence or metastatic disease. Results: A systematic literature search identified nine cases of femoral artery leiomyosarcoma; in the eight patients for whom follow-up data were reported, recurrent or metastatic disease developed in five and only three were alive and free of disease. Conclusions: As with any soft tissues sarcoma, complete surgical resection is the cornerstone of treatment and any directly involved adjacent structures must be sacrificed, as well as a margin of uninvolved normal tissue; consequently, a vascular reconstruction is almost always necessary.
