Coagulation abnormalities and thrombosis have been recently identified as sequelae of severe infection with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We report a case of severe coagulopathy manifesting with right upper limb arterial and deep vein thrombosis in an 80-year-old male patient with severe COVID-19 associated pneumonia. He clinically deteriorated and received care in the intensive care unit where he was intubated. At that point, his coagulation laboratory tests were deranged, and he eventually developed dry gangrene in his right thumb and index finger, as well as a deep venous thromboembolism in his right axillary vein. Despite receiving treatment dose anticoagulation and undergoing arterial embolectomy, revascularization was unsuccessful. Amputation of the right arm at the level of the elbow was considered, but the patient died from respiratory failure.

CT-guided lung biopsy is a widely used procedure for tissue identification. The complications are divided into minor and major with the latter being described as low rate. Hemothorax is reported at a rate of 0.092% and predominantly results from the injury of intercostals or internal mammary arteries. We present the case of 81-year old woman with a right upper lobe mass referred for a CT-guided biopsy. Four hours after the procedure, rapid deterioration of patient's status was observed. A massive hemothorax was reported due to the transection of an intratumoral pulmonary branch. The following management involved successful emergent embolization of the injured branch of the pulmonary artery using a combination of coils and gel foam. One of the theories possibly explaining this extremely rare complication involves the possibility of underlying pulmonary hypertension.

Purpose. To retrospectively evaluate the effectiveness of intra-articular application of Sluijter-Teixera Poisson pulsed radiofrequency (STP PRF) in knee osteoarthritis symptomatic patients with chronic pain refractory to conservative therapies. Materials and Methods. Institutional database research of two centers identified 39 cases of knee osteoarthritis patients treated with intra-articular STP PRF. Pain prior and one-week and one-, three-, six-, and twelve-month post-STP PRF was compared by means of a numeric visual scale (NVS) questionnaire. Cardiovascular and Interventional Radiological Society of Europe (CIRSE) classification system was used for complications reporting. Mean patient age was 71.59 ± 11.99 years, mean body mass index was 30.23 ± 4.69, and male/female ratio was 9/30. Results. Mean baseline pain score was 8.31 ± 1.70 NVS units. This was reduced to a mean value of 0.90 ± 1.50 NVS units one-week post-RF, 1.08 ± 1.53 at one month, 1.54 ± 1.88 at three months, 2.33 ± 2.17 at six months, and 3.23 ± 2.23 at 12 months of follow-up . Pain decrease of more than 4 NVS units was noticed in 35/39 knees (89.7%) at first week, 36/39 knees (92.3%) at first month, 35/39 knees (89.7%) at three months, 32/39 knees (82.1%) at six months, and 25/39 knees (64.1%) at one year. There was no recurrence during the follow-up. No complication was observed. Conclusions. Percutaneous, intra-articular application of STP PRF is an effective and safe technique for chronic pain reduction in patients with knee osteoarthritis. Results seem to be reproducible and long lasting with significant patient satisfaction at 12-month follow-up.

Background/Objectives: Percutaneous kidney biopsy (PKB) is a valuable diagnostic tool for evaluating renal masses and suspected renal cancer but carries a risk of hemorrhagic complications. This study aimed to determine whether injecting a hemostatic Gelfoam mixture into the biopsy tract reduces post-procedural bleeding while maintaining diagnostic accuracy. Methods: This retrospective study included 500 patients who underwent PKB at our hospital between 2019 and 2024. Patients were equally divided into two groups: Group A (n = 250) received Gelfoam injection into the biopsy tract, and Group B (n = 250) underwent standard PKB without Gelfoam. Hemorrhagic complications were categorized as mild, mild–moderate, moderate, or severe based on immediate and 4-h post-procedure CT findings. Management protocols included same-day discharge for mild cases (with next-day re-evaluation) and 24-h observation for mild–moderate cases. Results: Group A had significantly fewer moderate–severe hemorrhages compared to Group B (1.3% vs. 4.0%, p = 0.034) and a higher rate of same-day discharge (84% vs. 40%, p < 0.05). These differences led to a notable reduction in total hospitalization days (43 vs. 167) and decreased overall costs. Diagnostic yield was similarly high in both groups (98.5% vs. 97.8%, p = 0.72). Conclusions: Gelfoam injection during PKB effectively reduces hemorrhagic complications and shortens hospital stay without compromising diagnostic accuracy. Routine use of Gelfoam—especially in high-risk patients—is supported by these findings, and further prospective studies are recommended to validate these results.

The aim of this study is to evaluate the safety and efficacy of the use of the IMACTIS^® CT-Navigation™-electromagnetic navigation system (EMNS) in cryoablation CT-guided procedures under local anesthesia for the treatment of upper kidney pole and adrenal lesions. We conducted a retrospective analysis of patients with upper kidney pole lesions and adrenal metastases who underwent cryoablation using the IMACTIS-CT^®-EMNS between January 2019 and April 2023. The EMNS was used to guide the placement of the cryoprobes with CT guidance under local anesthesia. The primary outcome was technical success, defined as the successful placement of the cryoprobes in the target lesion. A total of 31 patients were studied, of whom, 25 patients were treated with cryoablation for upper pole kidney masses, and 6 patients underwent the cryoablation of adrenal metastases during the study period. The mean age was 60 years (range, 36–82 years), and 21 patients were male. All the upper kidney pole lesions were renal cell carcinomas, and regarding adrenal metastases, the primary cancer sites were the lungs (n = 3), breast (n = 2), and the colon (n = 1). The median size of the lesions was 3,8 cm (range, 1.5–5 cm). All procedures were technically successful, with the cryoprobes accurately placed in the target lesions under CT guidance using the EMNS, avoiding the penetration of any other organs using an oblique trajectory. No major complications were reported, and local tumor control was achieved in all cases. Our initial experience using the EMNS for cryoprobe placement during CT-guided interventional procedures under local anesthesia for the cryoablation treatment of upper pole kidney lesions and adrenal metastases showed that it is safe and effective.

Aortocaval fistulas, typically linked to aortoiliac aneurysms, are rare vascular conditions. Currently, endovascular therapy is preferred treatment approach. However, endovascular therapy requires frequent and extended follow-up evaluations. Herein, we emphasize a noteworthy clinical finding in this disease: the presence of a pulsatile femoral vein. Additionally, we propose a novel, simple, and easily performed radiation-free method for postoperative assessment of fistula presence or resolution: duplex ultrasound of the femoral vein. While duplex ultrasound cannot substitute other diagnostic modalities, this technique offers a quick, cost-effective, and repeatable adjunct for monitoring.
