Rare Complications of Uterine Fibroid Embolization (UFE)

Introduction

Technological progression piloted the blooming of novel and contemporary interventions for disease tackling. Both diagnostic and curative interventions evidenced advent. Newer interventional strategies were devised and phased in to scale down and sidestep the intricacies that conventional treatment could bring out. However, they do project some rare complications. So, irrespective of the interventions, precise post-operative monitoring ought to be instituted to pin down and shut off the gravity for complications.

What Is Uterine Fibroid Embolization?

Uterine fibroid embolization (UFE), otherwise quoted as uterine artery embolization, is a minimally invasive strategy instituted as a stand-in choice to intercept an advancing uterine fibroid. Uterine fibroids are aberrant and anomalous cellular gatherings (tumors) that crop up inside the womb (uterus). These uterine fibroids do not exhibit attributes of cancer or malignancy. Uterine fibroids could evolve or turn up in the womb wall, beneath the womb lining, or deep down the womb lining. Overstated menstrual bleeding, abdominal cramps, spotting midway between periods, painful sex, and lengthy periods are confronted with uterine fibroids. Uterine fibroids that pull off apparent and troubling manifestations call forth surgical extraction. Myomectomy (only the fibroid is extracted) and hysterectomy (entire womb extracted) are distinct surgical modalities advocated for uterine fibroids. Having said that, such surgical procedures are more intensive, mandating a protracted recovery phase.

Uterine fibroid embolization is a stand-in choice to counter the traditional surgical proceeding for uterine fibroids. Contrary to myomectomy and hysterectomy, uterine fibroid embolization does not call for traumatic fibroid extraction. Uterine fibroids dictate blood flow to upkeep and perpetuate their growth. Therefore, upon shutting off the blood supply, the uterine fibroids’ growth gets muted and even grades down. Uterine fibroid embolization institutes this principle to slim down the uterine fibroid. Minute particles are driven into the blood vessels that nourish the uterine fibroids. The catheter (a flexible pipette-like medical equipment) drives those minute particles into the pertinent blood vessel. These particles seed and expedite clot formation. The clot will then fade down the bloodstream that feeds and nurtures the uterine fibroid.

What Are the Rare Complications Precipitated by Uterine Fibroid Embolization?

Uterine fibroid embolization, contrary to standard uterine fibroid surgeries, brings out superior and productive outcomes with the least prospect for complications. However, it rarely brings forth certain intricacies. The following are some of the rare intricacies that uterine fibroid embolization could pull off:

• Arterial Dissection: While wedging and thrusting the catheter down the blood vessel, it could rip up or scratch the blood vessels, instigating arterial dissection. In uterine fibroid embolization, the artery at the groin region (femoral artery) is customarily chosen for wedging the catheter.

• Pseudoaneurysm: The driven catheter may inflict laceration or cut in the artery. Through the cut, blood may seep out and stockpile in proximity to the leak point. Owing to its resemblance with an aneurysm (outpouching of the arterial wall), it is named as pseudoaneurysm.

• Thromboembolic Events: Following uterine fibroid embolization, one ought to be immobilized. Though the period is small, it could deepen the gravity of deep vein thrombosis, where aberrant clots configure within a deeper vessel. These clots may plug in and obturate the bloodstream, warding off oxygen and nutrient dissipation to specific sites. Once the blood vessels that feed the lungs are sealed by such clots, it brings forth pulmonary embolism.

• Uterine Ischemia: In uterine fibroid embolization, the bloodstream that feeds and caters to the fibroids is intentionally sealed off. However, at times, uterine fibroid embolization may mute the uterine blood flow, which in turn prompts uterine ischemia owing to oxygen and nutrient undersupply.

• Uterine Infections: Another infrequently encountered complication prompted by uterine fibroid embolization is uterine infection. Post uterine fibroid embolization one ought to be tracked for infection signs. Upon encountering uterine infection, antibiotic therapy needs to be advocated at the earliest to stamp out the uterine infection. Otherwise, the uterine infection may headway, eventually mandating a hysterectomy. When the uterine infection is delimited with the inside layer (endometrium), it is marked as endometritis.

• Uterine Necrosis: Uterine necrosis, though rare, is an alarming intricacy that uterine fibroid embolization could call forth. In uterine necrosis, the cellular components in the womb turn nonvital and dead. The minute particles instituted purposefully to coke the nutrient for uterine fibroid could also upgrade the proclivity for sealing the uterine bloodstream. The poly-vinyl alcohol agent that is employed in uterine fibroid embolization expedites the blood vessel-blocking owing to its embolizing attributes. Poly-vinyl alcohol agents underscore the threat of uterine necrosis.

• Multiorgan Failures: Instances of multiorgan failure, where many organs collectively and concomitantly bring out troubles in executing and eliciting their functions, are also documented with uterine fibroid embolization. Multiorgan failures derange the way in which normal activities are being accomplished, thereby risking one’s life. Blood infection or embolism could pull off multiorgan failures post-uterine fibroid embolization.

• Ovarian Dysfunction: In uterine fibroid embolization, the clot is intentionally fostered by employing external embolizing agents. At times, these agents that are dispensed through the catheter to mute the fibroid’s blood supply may be wrongly guided onto ovarian blood vessels. It could instigate aberrations in the ovary functions and even call forth ovarian failure (the ovary pauses all its activities).

• Sexual Dysfunctions: Uterine fibroid embolization may, at times, bring forth anorgasmia (failure to bring out orgasm) owing to unintended choking of cervicovaginal arteries through the procedure. However, over time, these sexual dysfunctions projected by uterine fibroid embolization clear up gradually.

• Radiation Injury: Uterine fibroid embolization technique is teamed with imaging modalities like X-ray. Therefore, though rare, it could bring out radiation injuries.

• Contrast Nephropathy: In uterine fibroid embolization, to track and guide the catheter and to underscore the attributes of uterine fibroids, contrast agents are advocated alongside imaging modalities. These contrast agents could inflict kidney harm, which, in turn, downturn the kidney functions.

Conclusion

Uterine fibroid embolization, though a novel and safer modality, also holds up the threat of certain complications. However, complications are not a regular scenario concerning uterine fibroid embolization. Uterine fibroid embolization turns down the hospital stay and expedites the recovery process. It also projects a striking success rate in downgrading uterine fibroids. Understanding and keeping one mindful of the possible intricacies that uterine fibroid embolization strategy could bring out is imperative to gear down such instances. Remedial measures tend to be driven by the type of complication that breaks out. Instituting prompt therapeutics and medicaments are key integrants in downgrading the complications. Uterine fibroid embolization is a harmless and promising standby for those who are reluctant to take up an explorative surgery to ward off their uterine fibroid.
