Hybrid Repair Combined with Fresh Arterial Allograft Extra-Anatomical Reconstruction: The Treatment of Infrarenal Abdominal Aneurysm above an Aortobifemoral Bypass Complicated by an Infected Pseudoaneurysm in the Left Groin
Introduction. A 72-year-old male patient was admitted into our centre with large infected pseudoaneurysm (PSA) in the left groin. The patient underwent a CT angiography (CTA) that confirmed a large partly thrombosed cm PSA in the left groin arising from the distal anastomosis of the aortobifemoral bypass (ABF). Furthermore, the CTA revealed 11 cm juxtarenal abdominal aortic aneurysm (JAAA) from which the proximal anastomosis of the ABF was arising. Method. Aorto-uni-iliac stent graft Cook was placed from the right groin trough native severely stenotic right iliac arteries with proximal landing zone below the renal arteries, excluding the JAAA and the ABF. The distal landing zone was in the common iliac artery maintaining patent right internal iliac artery. Afterwards, a femoro-femoral crossover bypass from right to left was performed using a fresh arterial allograft. Postprocedurally, the hospital stay was uneventful. The left groin PSA cultures came positive for Staphylococcus epidermidis and Corynebacterium tuberculostearicum, both sensitive to vancomycin and rifampicin. Result. The patient underwent intravenous ATB treatment with vancomycin for two weeks, followed by four weeks of oral rifampicin. The patient was discharged on the 20th postoperative days. Conclusion. Hybrid repair combining aortic stent graft and extra-anatomical bypass in the treatment of infected distal parts of an aortofemoral bypass is an acceptable treatment modality.
Delayed Yet Successful Mechanical Thrombectomy for Phlegmasia Cerulea Dolens in a Limb with Severe Arterial Disease and May-Thurner Syndrome
Phlegmasia cerulea dolens (PCD) is a rare but life-threatening complication of acute deep venous thrombosis that lacks consensus regarding the approach to management. We present a case of PCD developing shortly after a spinal surgery and manifesting as acute swelling and discoloration in a leg with existing severe atherosclerotic arterial disease. The patient’s critical limb ischemia was completely and rapidly reversed by percutaneous mechanical thrombectomy using the ClotTriever device despite a delay in treatment. An underlying iliac vein compression “May-Thurner” syndrome was discovered using intravascular ultrasound and treated with angioplasty. This case identifies mechanical thrombectomy using the ClotTriever system as a possible effective and safe treatment for PCD.
Hybrid Solution for Mycotic Pseudoaneurysm of Carotid Bifurcation
Mycotic pseudoaneurysms of the extracranial carotid artery are rare and need surgical treatment to prevent rupture or embolization. We treated a case of a carotid bifurcation pseudoaneurysm secondary to infection caused by Staphylococcus epidermidis. We successfully treated it using a catheter balloon to obtain carotid bifurcation’s control and replacing the carotid bifurcation with a vein graft. Management involves aneurysmectomy associated with antibiotic therapy and restoration of arterial continuity.
Carotid Thrombosis in a Crack Cocaine Smoker Woman
Introduction. We report a case of stroke in a crack smoker with occlusion of the middle cerebral artery and a large thrombus in the carotid artery. Case Presentation. A 34-year-old female presented with left upper arm weakness, associated with paresthesia with onset of symptoms more than 24 hours before. Angio-RM sequences showed an area of ischemia, with occlusion of the M2 segment of the middle cerebral artery. Carotid ultrasound showed a soft plaque with distal end floating. Anticoagulant treatment was started, and seriated ultrasound evaluations showed its gradual dissolution. Conclusions. In atherothromboembolic stroke from carotid thrombosis, repeated ultrasound studies may be useful for either diagnosis and monitoring the efficacy of anticoagulant therapy.
Bilateral Popliteal Artery Entrapment Syndrome: An Approach to Diagnosis and Salvage
Popliteal artery entrapment syndrome (PAES) is a rare cause of limb-threatening vascular disease. Usually, it arises from aberrant embryological development or acquired dysfunctionality of the popliteal artery and its surrounding musculotendinous structures in the popliteal fossa. Here, we present a case report of a young woman with relatively sudden-onset short-distance claudication and paraesthesia affecting her right leg primarily. She had no recent traumatic history and no atherosclerotic risk factors and was otherwise previously very active. She had a feeble right popliteal artery pulse and no foot pulses. Nerve conduction studies demonstrated no electrophysiological abnormalities. Following computed tomography angiography and magnetic resonance imaging, it was determined she had type 2 PAES. Subsequently, the patient underwent surgical division of a lateralised head of her medial gastrocnemius, resection of her fibrosed popliteal artery, and repair with a reversed long saphenous vein interposition graft. Following surgery, her symptoms resolved, and she remains on aspirin and ultrasound surveillance.
Life-Threatening Rupture of an Idiopathic Left Hepatic Artery Pseudoaneurysm Successfully Treated with Endovascular Coil Embolization
Hepatic artery pseudoaneurysm is a rare condition; they are multifactorial, most of them locating in the extrahepatic vasculature and the mortality associated to its rupture may reach up to 70%. We report a 77 years old female who was admitted due to headache and uncontrolled hypertension and that on her second hospital day developed sudden hemodynamic instability, abdominal pain, fatigue, skin-mucosa pallor, and anemia. Abdominal CT scan with contrast showed a left hepatic artery pseudoaneurysm associated with extensive hemoperitoneum. Patient required emergent hemodynamic stabilization and finally was treated successfully with a superselective endovascular coil embolization. Our patient represents an atypical case of a spontaneous rupture of an idiopathic hepatic artery pseudoaneurysm. Hence, the importance of having a high index of clinical suspicion. Endovascular coil embolization has become the first-line treatment.
