Project description:Pulmonary artery pseudoaneurysm (PAP) is a rare vascular phenomenon with a high mortality rate, as these entities can enlarge, rupture, and lead to asphyxiation. Pulmonary mucormycosis (PM), an underdiagnosed but an increasingly seen entity in the era of chemotherapy and immunosuppression, is a known cause of PAP, and should be suspected in immunosuppressed patients with hemoptysis. We present a case of PAP due to PM in a patient with recently diagnosed diffuse large B-cell lymphoma of the liver who underwent chemotherapy and developed acute cavitary lung disease and hemoptysis. His diagnosis was delayed due to the withholding of iodinated contrast with computer tomography (CT) imaging in the setting of renal failure. He then underwent embolization of his PAP with resolution of his hemoptysis. PAP is an uncommon cause of hemoptysis that can be diagnosed with CT pulmonary angiography, and mucormycosis is a known but rare cause of PAP in patients with malignancy receiving immunosuppression.

Project description:Literature on COVID-19-associated pulmonary mucormycosis (CAPM) is sparse. Pulmonary artery pseudoaneurysm (PAP) is an uncommon complication of pulmonary mucormycosis (PM), and rarely reported in CAPM. Herein, we report five cases of CAPM with PAP managed at our center and perform a systematic review of the literature. We diagnosed PM in those with clinico-radiological suspicion and confirmed it by microbiology or histopathology. We encountered five cases of CAPM with PAP (size ranged from 1 × 0.8 cm to ~ 4.9 × 4.8 cm). All subjects had diabetes and were aged 55-62 years (75% men). In two cases, COVID-19 and mucormycosis were diagnosed simultaneously, while in three others, COVID-19 preceded PM. One subject who underwent surgery survived, while all others died (80% mortality). From our systematic review, we identified one additional case of CAPM with PAP in a transplant recipient. CAPM with PAP is rare with high mortality. Early diagnosis and multimodality management are imperative to improve outcomes.

Project description:ObjectiveTo demonstrate the feasibility of percutaneous microwave ablation in desmoid fibromatosis with respect to tumor volume control and improvement in the quality of life.Materials and methodsTwelve microwave ablations were performed in 9 patients with a histological diagnosis of desmoid fibromatosis between January 2010 and January 2019. The study population included 6 female and 3 male, with an age range of 21-76 years (mean = 46.6 years; standard deviation [SD] = 19.3 years). The mean major axis of the tumors was 10.9 cm (SD = 5.2 cm) and mean lesion volume was 212.7 cm³ (SD = 213 cm³). Their anatomical distribution was as follows: 3 lesions in the thigh, 2 in the gluteus, 2 in the leg and 2 in the periscapular region. We evaluated the reduction in tumor volume and improvement in the quality of life based on the Eastern Cooperative Oncology Group (ECOG) scale.ResultsAn average tumor volume reduction of 70.4% (SD = 24.9) was achieved, while the quality of life (ECOG scale) improved in 88.9% of patients.ConclusionPercutaneous microwave ablation may potentially be a safe, effective, and promising technique for controlling tumor volume and improving the quality of life in patients with desmoid fibromatosis.

Project description:A 21 year-old male underwent nephrostomy tube insertion for hydronephrosis due to a large para-aortic adenopathy of a testicular tumor. In order to reduce infections during chemotherapy, a ureteral stent was placed. While removing the nephrostomy tube, a pulsatile bleeding was found and a renal angiography was done. A pseudoaneurysm of his first left lumbar (L1) artery communicating with the nephrostomy's access site was found. An embolization was performed with coils in the left L1 artery and one of its subdivisions. Post-embolization controls revealed no bleeding. On the follow-up CT, there were no suspicious retroperitoneal mass.

Project description:Pulmonary artery pseudoaneurysm is a very rare complication of penetrating thoracic trauma. We present a case of a 27-year-old woman who developed a 6.5-cm traumatic pulmonary artery pseudoaneurysm after suffering multiple stab wounds to the chest and the abdomen. The pseudoaneurysm was successfully treated endovascularly with vascular plug occlusion and coil embolization.

Project description:BackgroundCoronary artery pseudoaneurysms (PSAs) are uncommon and have poorly understood natural history. Unlike true aneurysms, PSAs do not have all the three layers of the vessel in the aneurysmal wall. The PSAs are most commonly seen after an overzealous percutaneous coronary intervention (PCI) which causes damage to the vessel wall. They usually develop slowly after PCI and PSAs within a month of a PCI are not so common. The PSA may be asymptomatic or present with recurrent angina.Case summaryHere, we report a case of symptomatic PSA to right coronary artery (RCA). The patient had a myocardial infarction for which a PCI was performed to deploy a drug-eluting stent (DES) in the RCA. The patient had in-stent restenosis (ISR) within a week of PCI for which plain old balloon angioplasty (POBA) was performed. The patient continued to have unstable angina and within a month of POBA was diagnosed as a case of PSA by intravascular ultrasound. A covered stent was deployed which effectively sealed off the PSA and resumed normal blood flow to distal vessel. Patient has been doing well on medication [aspirin 75 mg once daily, atorvastatin 80 mg once daily, and P2Y12 platelet inhibitor (Ticagrelor) 90 mg twice daily].DiscussionThe PSAs usually take 6-9 months to develop. However, PSAs have been reported within 1-2 months of PCI. This case also shows that PSAs can occur within a month of PCI. It is possible that over-aggressive and/or high-pressure dilatation and/or deep engagement during POBA performed to open up the ISR could have damaged the struts of the DES and compressed it against the vascular wall. The resultant vascular wall injury could have been the cause of early PSA formation in this case. Hence, cardiologists should be vigilant enough to suspect PSA, especially in a patient presenting with angina. The case also shows that covered stents are a viable option to treat early presentations of PSA.

Project description:BackgroundThe conventional diagnosis and treatment for highly suspected malignant pulmonary nodules (PNs) can avoid unnecessary treatment to some extent. However, the relatively separate puncture processes may not only increase puncture-related complications, but also increase the patient's radiation exposure and hospitalization costs. The purpose of this study was to retrospectively analyze the effectiveness of simultaneous percutaneous microwave ablation (MWA) and percutaneous biopsy (PB) for PNs.MethodsFrom August 2015 to August 2022, 65 consecutive patients [48 solid nodules, 6 ground glass opacities (GGOs), 11 mixed nodules] with suspected single malignant PN underwent MWA and PB combination treatments at the First Affiliated Hospital of Zhengzhou University. The total of 30 patients in Group A underwent synchronous PB and MWA (strategy: low-power MWA-PB-high-power MWA), whereas 35 patients in Group B underwent asynchronous PB and MWA. The technical success, complete ablation (CA), complications, total procedure time (TPT), patient exposure dose (PED), hospitalization time, and costs were compared. An independent samples t-, χ2, or Fisher's exact tests were used.ResultsThe technical success (100% vs. 100%) and CA (100% vs. 97.1%) rates were not significantly different between Groups A and B. The complications of intrapulmonary hemorrhage (16.7% vs. 41.4%, P=0.02) and hemoptysis (0% vs. 8.6%, P=0.04) were significantly different between Groups A and B. TPT (41.6±7.9 vs. 57.3±8.8 min, P<0.001), PED (12.9±1.4 vs. 19.4±2.3 mSv, P<0.001), hospitalization stay (4.7±1.3 vs. 9.1±2.1 days, P<0.001) and costs (3,768.8±652.9 vs. 4,508.0±514.1 USD, P<0.001) also showed significant differences between Groups A and B.ConclusionsSynchronous PB and MWA for PNs is a safe and effective strategy that can decrease bleeding, PED, the hospitalization stay, and costs.

Project description:Microwave ablation is a developing treatment option for unresectable lung cancer. Early experience suggests that it may have advantages over radiofrequency (RF) ablation with larger ablation zones, shorter heating times, less susceptibility to heat sink, effectiveness in charred lung, synergism with multiple applicators, no need for grounding pads, and similar survival benefit. Newer microwave ablation devices are being developed and as their use becomes more prevalent, a greater understanding of device limitations and complications are important. Herein we describe a microwave lung ablation complicated by bronchocutaneous fistula (BCF) and its treatment. BCF treatment options include close monitoring, surgical closure, percutaneous sealant injection, and endoscopic plug or sealant in those who are not surgical candidates.

Project description:BackgroundPopliteal artery pseudoaneurysm is a state of vascular wall rupture in the popliteal artery. It is generally a rare situation and the most common etiologic factor is iatrogenic causes.Case presentationThis case report presents a successful diagnosis and management of a 31-year-old patient who was presented with a mass behind the knee, three months after femoropopliteal bypass for the treatment of a gunshot to the knee. An endovascular approach using coils was utilized for the patient, which led to complete remission for the patient.DiscussionThe current patient had two primary therapeutic challenges: bleeding and hematoma growth, clot development causing blood flow restriction, and limb ischemia. Pseudoaneurysm also caused internal inflammation, which increased the risk of thrombosis and bypass graft damage during open surgery. Due to the risk of recurrence and graft damage, ultrasound-guided compression was not possible. Thus, endovascular therapy was preferred.ConclusionThe endovascular approach using coils is an option for the management of PAP. However, the endovascular approach should be considered carefully according to the patient's status.
