Midterm outcomes of rotational atherectomy-assisted endovascular treatment of severe peripheral arterial disease.

OBJECTIVE: We evaluated the midterm results of atherectomy-assisted angioplasty for the treatment of femoropopliteal lesions and the identification of possible subgroups of patients with superior outcomes. METHODS: We conducted a single-center, physician-initiated, nonindustry-sponsored retrospective analysis of patients with Rutherford category ranging from II to V and de novo occlusive or stenotic lesions of the superficial femoral (SFA) and/or popliteal arteries treated with atherectomy-assisted angioplasty (Jetstream rotational atherectomy + drug-eluting ballooning). In cases of subintimal recanalization or patients without an SFA stamp, with previous ipsilateral bypass surgery, systemic coagulopathy, end-stage renal disease requiring hemodialysis, life expectancy of <12 months, and intolerance to aspirin, clopidogrel, and/or heparin were excluded. RESULTS: In a total of 103 enrolled patients, the median SFA and/or popliteal lesion length was 80 mm (interquartile range, 61.2 mm) with 73 lesions being occlusive (70.9%) and 84 (81.5%) classified as Fanelli calcification score 3 and 4. Technical success was met in 96.1% of cases (n = 99) at a median operative time of 108 minutes. Adjunctive stenting was needed in 10 patients (9.8%). At a median follow-up of 18.0 ± 10.8 months, Rutherford class clinical improvement was present in 77 patients (74.8%), and 7 patients (6.79%) presented target lesion occlusion needing reintervention in 6 cases (5.82%). The primary patency rates were 97% at 12 months and 83% at 24 months with secondary patency rates of 99% at 12 months and 91% at 24 months of follow-up. There were no significant differences when treating differently located lesions, diabetic vs nondiabetic patients, or comparing experienced vs nonexperienced operators. CONCLUSIONS: The use of rotational atherectomy and drug-eluting balloons for the treatment of severe femoropopliteal disease showed relatively low need for bailout stenting and good midterm primary patency rates. The influence of lesion location, diabetes mellitus, or operator experience did not show statistically different results in terms of patency. Longer term outcomes and comparative analysis are needed to consolidate further clinical evidence.

Von Gierke Disease (Glycogen Storage Disease Type I) and Life-Threatening Abdominal Aortic Aneurysm: A Case Report of an Extremely Rare Condition.

Von Gierke disease, also known as glycogen storage disease type I, co-existent with an abdominal aortic aneurysm (AAA), is an extremely rare combination of diseases that requires challenging therapeutic measures. We present, for the first time in literature, the case of a 62-year-old female with von Gierke disease who required open surgical repair of an AAA with challenging neck anatomy outside of instructions for use of endovascular repair. Even though the surgical risks for life-threatening complications, such as pancreatitis, metabolic acidosis, and kidney failure, were high, the 6-month postoperative course was uneventful. Despite the invasiveness of the treatment, surgery to treat the AAA was safe and effective. Further data is needed to draw robust conclusions about the treatment of choice for those patients with diseases in co-existence with AAAs.

Periprocedural Outcomes of Rotational Atherectomy-Assisted Balloon Angioplasty in Isolated Atherosclerotic Popliteal Artery Lesions: The ISO-POP Trial.

BACKGROUND: Treatment of calcified popliteal artery lesions represents an ongoing challenge for vascular specialists. Biomechanical forces of external compression, torsion and elongation that occur with locomotion in the popliteal segment can lead to stent fractures and occlusions. The aim of our study was to assess the procedural success rate of atherectomy in combination with balloon angioplasty for isolated calcified popliteal artery lesions. METHODS: Between January 2020 and December 2022, 62 patients with isolated atherosclerotic lesions of the popliteal artery underwent endovascular treatment by use of rotational atherectomy (Phoenix, Philips USA, (subgroup A) or Jetstream, Boston USA, (subgroup B), atherectomy systems) and additional balloon angioplasty in two vascular centers. The primary outcome measures were: 1. periprocedural clinical and technical success (<30% residual stenosis and no need for bailout stenting due to flow-limiting dissection) and 2. postprocedural increase in the ankle brachial index of more than 0.1. RESULTS: The overall rate of bailout stenting was 4.8%, whereas the procedural success rate was 98.4%. The rate of procedural complications included 3.7% and 5.7% peripheral embolizations in the subgroups A and B, respectively, and no vessel perforations were noted. All embolizations were successfully treated by catheter aspiration or capture in the pre-treatment placed filter system. In addition, 1 (3.7%) pseudoaneurysm in the groin was reported in subgroup A and treated by surgical means. Median ABI of the affected limbs improved from 0.55 (0.2) to 0.70 (0.2) in subgroup A and from 0.50 (0.2) to 0.95 (0.1) in subgroup B (DABI of 0.15 versus 0.45, p < 0.001). CONCLUSIONS: The combination of rotational atherectomy and balloon angioplasty in the popliteal artery showed reproducible outcomes in 2 centers, with low incidence of complications and low rates of bail-out stenting. These findings may contribute to more liberal use of such devices especially in segments with high risk for stent factures and occlusions.

An Enigmatic Case of an Uncommon Syndrome: The Hughes-Stovin Syndrome.

Hughes-Stovin syndrome is a disorder characterized by deep vein thrombosis and pulmonary artery aneurysms with potentially life-threatening complications. The case of a 22-year-old Moroccan male patient, presenting with signs of sepsis of unclear etiology, is presented here. Computed tomography (CT) scan revealed thrombosis of the inferior vena cava up to the hepatic veins, thrombosis of both common iliac veins and a thrombus in the right atrium. Primarily suspecting septic thrombosis, surgical thrombectomy was performed. The patient recovered uneventfully and was discharged with oral anticoagulants. Three weeks later, he was admitted again with acute shortness of breath. A new CT scan showed bilateral pulmonary embolism and multiple pulmonary artery aneurysms. Hughes-Stovin syndrome was diagnosed, and high-dose heparin and an immunosuppressant (prednisolon) were administered. Two weeks later, the patient presented again with massive epistaxis and hemoptysis. A CT scan showed diffuse parenchymal bleeding. After prophylactic intubation and conservative treatment, he recovered rapidly and was again discharged uneventfully. Under immunosuppressants, a rapid reduction in the diameter of the pulmonary aneurysms was observed and the patient remained symptom-free during follow-up.

A Synovial Cyst Originating from the Hip Joint as a Rare Cause of Recurrent Femoral Vein Thrombosis: Case Report and Literature Review.

Thrombosis of the femoral vein may be caused by external obstruction. A 48-year-old female patient presented with leg swelling and a history of recurrent femoral venous thrombosis caused by a ganglion originating from the left hip joint. A computer tomography-guided puncture had also been performed, which was followed by rapid refilling of the cyst. Thereafter, the femoral vein was decompressed, and the ganglion was resected. Pathology confirmed a synovial cyst. After an uneventful stay, the patient was discharged on oral anticoagulation. Follow-up showed no further compression of the femoral vein. This case report describes a rare case of recurrent femoral venous thrombosis caused by a synovial cyst.

Thrombosis of the Inferior Vena Cava after Endovascular Aortic Repair in a Patient with May-Thurner Syndrome: Case Report and Literature Review.

Inferior vena cava (IVC) thrombosis is a rare complication of abdominal aortic aneurysm (AAA). A 70-year-old male patient of Italian origin presented with a 9.3 × 8.4 cm infrarenal AAA, which was treated by endovascular aortic repair (EVAR). He reported a history of ulcerative colitis and was on prednisolone 80 mg daily. Seven weeks postoperatively the patient was readmitted with a deep vein thrombosis including both iliac veins and IVC, and bilateral pulmonary embolism. Venous thrombectomy and decompression of the IVC were performed by partial resection of the aneurysm sac. A covered stent was intraoperatively placed in the left common iliac vein to treat compression of the left iliac vein (May-Thurner Syndrome). Enoxaparin (2 × 0.8 mg) and antiplatelet agent with aspirin were administered, as well as intermittent compression therapy to the left leg. This case report describes vena cava thrombosis as a rare complication after EVAR in a patient with May-Thurner syndrome.
