Vertebroplasty-associated cement leak leading to iatrogenic venous compression and thrombosis

Effect of percutaneous vertebroplasty on the treatment of osteoporotic spinal fractures in elderly patients and risk factors for postoperative lower extremity deep vein thrombosis

OBJECTIVE

To evaluate the effectiveness of PVP (PVP) in treating osteoporotic spinal fractures in the elderly and analyze the risk factors for postoperative deep vein thrombosis (DVT) in the lower extremities.

METHODS

A total of 100 elderly patients with osteoporotic spinal fractures, treated between August 2019 and July 2021, were divided into two groups: PVP (research group, n=50) and conservative treatment (control group, n=50). Outcome measures, including injured vertebrae, pain levels, and treatment outcomes, were retrospectively analyzed. Patients who underwent PVPs were further categorized based on the presence of lower extremity DVT one month post-surgery. Logistic regression analysis was used to identify risk factors for post-surgical lower limb DVT.

RESULTS

PVP resulted in a significantly smaller posterior convexity angle of the injured spine and higher anterior, midline, and posterior edges of the injured spine compared to conservative treatment (P<0.001). Patients in the research group had significantly lower visual analogue scale (VAS) scores and higher treatment efficiency compared to those in the conservative treatment group (all P<0.05). Nine cases of lower extremity DVT were observed after PVP. Logistic regression analysis identified age, body mass, smoking, and diabetes as independent risk factors for post-surgical lower extremity DVT.

CONCLUSION

PVP improves spinal function and relieves pain in elderly patients with osteoporotic fractures. However, age, body mass, smoking, and diabetes are independent risk factors for postoperative lower extremity DVT.

Case report: Shock after percutaneous vertebroplasty of the 5th thoracic vertebra

Background

Percutaneous vertebroplasty (PVP) is a common treatment for osteoporotic vertebral compression fracture (OVCF). Perioperative bleeding is usually rare, so there are few reports of shock. However, we developed shock after treating a case of OVCF of the 5th thoracic vertebra with PVP.

Case presentation

An 80 years old female patient received PVP due to OVCF of the 5th thoracic vertebra. The operation was successfully completed and the patient returned to the ward safely after the operation. At 90 min after operation, she developed shock, which was induced by subcutaneous hemorrhage up to 1500 ml at the puncture site. Before using vascular embolization, transfusion and blood transfusion were used to maintain blood pressure, and local ice bag compression was used to reduce swelling and stop bleeding, which achieved successful hemostasis. She recovered and discharged after 15 days, with the hematoma having absorbed. There was no recurrence during the 17-month follow-up.

Conclusion

Although PVP is considered to be a safe and effective method to treat OVCF, the possible hemorrhagic shock still needs to arouse the vigilance of surgeons.

Society of Interventional Radiology Position Statement on the Endovascular Management of Acute Iliofemoral Deep Vein Thrombosis

PURPOSE

To establish the updated position of the Society of Interventional Radiology (SIR) on the endovascular management of acute iliofemoral deep vein thrombosis (DVT).

MATERIALS AND METHODS

A multidisciplinary writing group with expertise in treating venous diseases was convened by SIR. A comprehensive literature search was conducted to identify studies on the topic of interest. Recommendations were drafted and graded according to the updated SIR evidence grading system. A modified Delphi technique was used to achieve consensus agreement on the recommendation statements.

RESULTS

A total of 84 studies, including randomized trials, systematic reviews and meta-analyses, prospective single-arm studies, and retrospective studies were identified and included in the review. The expert writing group developed 17 recommendations that pertain to the care of patients with acute iliofemoral DVT with the use of endovascular venous interventions.

CONCLUSIONS

SIR considers endovascular thrombus removal to be an acceptable treatment option in selected patients with acute iliofemoral DVT. Careful individualized risk assessment, high-quality general DVT care, and close monitoring during and after procedures should be provided.

A comparative analysis of the efficacy and safety of therapeutic interventions in phlegmasia cerulea dolens

OBJECTIVE

Present an institution's experience in management of phlegmasia cerulea dolens (PCD) with a review of the literature.

METHODS

Beaumont Health's electronic record database was queried between July 2009 and November 2019 for inpatients with PCD. A comprehensive chart review was performed to verify the accuracy of the diagnosis and extract relevant parameters. Medians and proportions are reported.

RESULTS

22 patients met the criteria for PCD. 59% females. Median age 65 years (interquartile range [IQR] 22). Obesity was present in 45% of patients. 18 patients underwent either a single modality (55.5%) or a multimodality therapeutic approach (44.5%). Limb amputation was required in a third of patients who underwent catheter-directed thrombolysis or percutaneous thrombectomy alone. Death was highest after percutaneous thrombectomy alone (66%) followed by pharmacomechanical catheter-directed thrombolysis alone (50%).

CONCLUSION

Percutaneous interventions have become the mainstay in management of PCD as demonstrated in this large retrospective analysis and supported by literature review.

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.
